Any and all applications for which a foreign or domestic priority claim is identified in the Application Data Sheet as filed with the present application are hereby incorporated by reference under 37 CFR 1.57.
Communication among low-cost devices is useful in many applications. For example, in a home environment, room occupancy sensors, light switches, lamp dimmers, and a gateway to the Internet can all work together if they are in communication. Residents of the home interact with the home-control system for monitoring and control. A user could, through a user-interface, configure the home-control system to illuminate a room in a home when people are present, and sound an alarm, depending on conditions the user sets up, for example.
As the number of controllable devices in the home rises, the possible actions between the devices become increasingly complex. If the user desires to utilize various combinations of device interactions, then the setup of the home-control network also increases in complexity. Thus, it is desirable to simplify the user interaction with the home-control network while utilizing the complex device interactions.
The cloud server downloads sensor information from the Internet, such as traffic patterns, weather information, and utility rates, for example. The cloud server can also receive sensor information from social media, such as Facebook®, and the like, associated with the user or others, and information from the user's smart phone, car, or work computer, for example. Further, the cloud server receives local network actions as well as the network actions from a plurality of home-control networks across a large geographic area, which can be subdivided with increasing granularity. In an embodiment, the cloud server receives the network actions from geographically close or neighboring home-control networks.
The cloud server aggregates the device actions. From the aggregate of the device actions, the cloud server creates snapshot behaviors, learned sequences, scenes, and timers, which can be continuously updated. The cloud server sends commands to the device via the network controller based on the sensor information to implement the snapshots, sequences, scenes, and timers.
For example, if the aggregate actions indicate that the hot tub heater is set to 100° C. fifteen minutes after the front door opens on sunny weekday afternoons, then the cloud server can send commands to the hot tub heater to turn on and set the water temperature to 100° C. when the weather is sunny, it is a weekday, and the user's smartphone is within a specified geo-fencing ring.
In addition, the cloud server can implement load-shedding behavior based on utility rates or a user-set sliding scale between comfort and economy. Further, analysis of network activity of others and broader web data allow learning and adjusting device behaviors based on such things as local neighborhood activity, and broader social connected activity. For example, the cloud server could use the neighbors' overall power usage to adjust the use of power on the user's home-control network. The cloud server could access friends' scenes for suggestions or improvements on the user's scenes.
The user can interface with the cloud server where the cloud server can send the device behavior to the device through the network controller and the network.

For purposes of summarizing the disclosure, certain aspects, advantages, and novel features of the inventions have been described herein. It is to be understood that not necessarily all such advantages may be achieved in accordance with any particular embodiment of the invention. Thus, the invention may be embodied or carried out in a manner that achieves or optimizes one advantage or group of advantages as taught herein without necessarily achieving other advantages as may be taught or suggested herein.
The features of the systems and methods will now be described with reference to the drawings summarized above. Throughout the drawings, reference numbers are re-used to indicate correspondence between referenced elements.

The embodiments described herein may comprise one or more of a sequence, a scene, and a timer. In an embodiment, a snapshot comprises a memorization of functional variables at a specific moment. For example, a user sets a thermostat to 78° C., selects cool mode, and then links the thermostat as part of a scene. The states of 78° C. and cool mode are memorized as part of the scene, then restored upon activation of the scene.
In another embodiment, a sequence comprises a memorized set of steps and variables that are started at a specific point and concluded after a desired number of iterations. There may be conditional logic statements within the steps of the sequence that change the way the sequence performs. For example, a thermostat may react to a network trigger by incrementing one degree, waiting a period of time, then incrementing again in order to reach a desired temperature. The thermostat raises the temperature gradually, over a period of time, instead of at the maximum rate of the HVAC system. The sequence concludes once the desired temperature has been reached.
In a further embodiment, a timer is a type of snapshot or sequence that is triggered by a real time clock reaching a selected time. For example, the thermostat in the previous scene and sequence examples could be triggered to reach the desired temperature at a selected time of day.
The communication system 240 is configured to propagate data and/or commands from the network controller or hub 250 to network devices and to propagate messages from the network devises to the network controller or hub 250. The communication system 240 is further configured to communicate with the cloud server 130 and with a user via a remote intelligent device, such as a smart phone, a personal computer, a laptop, a notebook, a tablet, or the like.
In other embodiments, the network 200 and/or communication system 240 can provide communication between the network controller 250 and one or more network devices in one or more facilities, buildings, residences, factories, stores, commercial facilities, industrial facilities, rooms, offices, zoned areas, subsystems, floors in a building, parking structures, stadiums, theatres, or the like, and is not limited to residences, homes, houses or the like.
The user can interact directly with the network controller 250 through the network controller's user interface, or the user can interface with the cloud server 130 where the cloud server 130 can send the device behavior to the network controller 250 or to the network device through the network controller 250 and the home-control network 200.
In an embodiment, the network 200 comprises a dual-band mesh area networking topology to communicate with network devices located within the network 200. In an embodiment, the network 200 comprises a home-control network. In an embodiment, the network 200 comprises an INSTEON® network utilizing an INSTEON® engine employing a powerline protocol and an RF protocol, which are described below in
The network controller 250 sends messages to and receives messages from the cloud server 130. Each network controller 250 sends network status associated with the corresponding network 200 to the cloud server 130. Further, each network controller 250 sends device status of the devices on the corresponding network 200 to the cloud server. In an embodiment, the device status and/or network status comprises one or more of a state of the network devices, commands sent to the network devices, responses from the network devices, queries from the network devices, and the like.
The cloud server 130 comprises a logical server that is built, hosted, and delivered through a cloud-computing platform over the Internet. In an embodiment, the cloud server 130 comprises a processor and memory. The memory comprises one or more databases and one or more web-based applications or programs where the processor is configured to access the databases and execute the programs to provide communication between the web-based applications and databases and the network controller 250. In an embodiment, the cloud server 130 receives messages and data from the plurality of network controllers 250 and is configured to aggregate the received messages and data. In an embodiment, the cloud server 130 aggregates the received messages and data according to a geographic area. The geographic area can be, for example, a home's neighboring houses, one or more streets, a city, a county, a state, and the like.
Further, the cloud server 130 receives cloud data from one or more websites or Internet accessible services. Examples of cloud data are weather data, traffic data, a celestial calendar such as a solar calendar or a lunar calendar, geographical location data, such as data from a geo-tracking device, social media communications, and the like.
In an embodiment, the cloud server 130 analyzes the aggregated network data from one or more networks 200. In another embodiment, the cloud server 130 accesses and analyzes the cloud data. In yet another embodiment, the cloud server 130 analyzes the aggregated network data and the cloud data. Based at least in part on the analysis, the cloud server 130 determines whether to send a message to the network device on the network 200 via the network controller 250 to control the network device. In an embodiment, the message comprises one of more of commands and data.
At step 2006, the cloud server 130 analyzes the network data and/or the cloud data. At step 2008, the cloud server 130 determines whether to take an action to control a device on the network 200 based at least in part on the analysis. If no action is determined, the process 2000 returns to step 2002.
If an action is determined, the process 2000 moves to step 2010, where a message is sent to the user associated with the network 200. In an embodiment, the user is contacted via one or more of text message, social media message, email, telephone call, voice mail, and the like. In an embodiment, sending a message to the user is optional. In an embodiment, the message requests confirmation from the user before the action is taken. In another embodiment, the message is sent to the user to report the action after the action is taken.
At step 2012, the cloud server 130 sends a message to the network controller 250 and the network controller 250 sends the message to the device on the network 200 to control the device. In an embodiment, the message comprises a command, which is received and acted upon by the device.
For example, a home-control network 200 may be set up such that outdoor lights illuminate at sunset, as determined by a solar calendar. However, the aggregated data for a mountainous geographic area indicates that lights are enabled on others' home-control networks 200 30-minutes earlier than sunset due the shadows cast by the mountains. The cloud server 130 may send the user a message suggesting that the lights illuminate 30 minutes ahead of the sunset or the cloud server 130 may send the lighting modules on the network 200 a command to enable earlier than sunset.
For example, the aggregated data over a plurality of home-control network 200 indicates that the majority of users run the lights at 80% of the full illumination to save on electricity costs. The cloud server sends the user a message asking if the user would like to change the illumination intensity of the lights on the user's home-control network 200.
For example, the aggregated data indicates that the neighbors set their thermostats to 78° C. and the network status indicates that the user sets his thermostat to 74° C. The cloud server 130 sends a message asking if the user would like to change the thermostat setting to 78° C.
For example, the users within a selected geographic area agree to offset the run times of their air conditioning units to avoid energy consumption spikes. The cloud server 130 receives the weather data and keeps track of when the HVAC units within the geographic area are enabled when the outside temperature is greater than 85° C., and automatically sends commands to the HVAC units on the networks 200 to interleave their run times.
For example, the cloud-server 130 receives weather data from the Internet, geo-location data from the homeowner's car via the Internet, and information from neighboring home-control networks 240. The cloud-server 130 analyzes the data which indicates that the temperature outside is predicted to drop below freezing in the next week, others in a similar location as the house have drained their water pipes, and the owner is far away. The cloud server 130 determines that the water sensor system should act to drain the water pipes in the house to prevent the water pipes from bursting.
At step 2104, the cloud server 130 accesses location data associated with the user. In an embodiment, the cloud server 130 accesses a geo-location application associated with the user's car.
At step 2106, the cloud server 130 accesses network messages from neighboring home-control networks 200.
In steps 2108-2114, the cloud server 130 analyzes the weather data, the location data, and the neighbors' network data. At step 2108, the cloud server 130 determines whether a predetermined percentage of neighbors have drained their watering system, based at least in part on the aggregated message data. In an embodiment, the predetermined percentage is 50%. In other embodiments, the predetermined percentage is greater than 50% or less than 50%.
If the predetermined percentage of neighbors have drained their watering system, the process 2100 moves to step 2112, where the cloud server 130 determines if a freeze event is expected in the next 24 hours, based at least in part on the weather data. If the freeze event is expected, the process 2100 moves to step 2114, where the cloud server 130 determines whether the user is far from the user's home-control network 200, based at least in part on the location data.
If the user is far from his home-control network 200, the cloud server 130, at step 2116, informs the user that the outside watering system will be drained to prevent damage to the pipes and the cloud server 130 at step 2118 sends a command to the water valve on the user's home-control network 200 to open to drain the water from the pipes.
If any of the conditions do not occur, such as neighbors have not drained their watering systems, a freeze event is not expected, or the user is close to the user's home-control network 200, the cloud server 130 performs a different analysis or rule set at step 2110.
The above scenarios comprise examples of cloud server adaptive learning and are not limiting.
In an embodiment, the network controller 250 receives sensor information from the cloud server 130 and/or the network controller 250 could have its own sensors, such as a clock, calendar, or light sensor. The network controller 250 sends commands to the network device 220 based on the sensor information to implement learned behavior.
In another embodiment, the network controller 250 also receives from the cloud server 130 stimulus data, such as information from Facebook®, information from the user's smart phone, car, or work computer, traffic patterns, weather, or utility rates. The network controller 250 sends commands to the network device 220 based on the sensor information and stimulus data to implement learned behavior.
In the illustrated embodiment, the home-control network 200 comprises exemplary network devices 220, such as one or more of a door controller 220DOOR, a window-blind controller 220WIN, a water valve controller 220WATER, a leak sensor 220LEAK, a motion sensor 220MOTION, an alarm 220ALARM, a thermostat 220THERM, a lighting module 220LED, a ceiling fan 220FAN, and the like.

The plurality of sensors 260 are configured to provide sensor data to the network controller 250. In an embodiment, the sensors 260 provide sensor data to a sensor input of the network controller 250, independent from the message data on the network 200. Examples of sensors 260 are one or more of a temperature sensor, a motion sensor, a light detector, a soil moisture sensor, a rain gauge, a snow gauge, a gas sensor, a flow meter, a wind meter, and the like.

The processor 1815 provides program logic and memory 1820 in support of programs 1825 and intelligence within the network controller 250. In an embodiment, the processor 1815 comprises a computer and the associated memory 1820. The computers comprise, by way of example, processors, program logic, or other substrate configurations representing data and instructions, which operate as described herein.

The memory 1820 can comprise one or more logical and/or physical data storage systems for storing data and applications used by the processor 1815 and the program logic 1825. The program logic 1825 may advantageously be implemented as one or more modules. The modules may advantageously be configured to execute on one or more processors.

In an embodiment, the processor 1815 executes the programs or rule sets 1825 stored in the memory 1820 to process cloud data, sensor data, and network messages. The processor 1815 receives sensor data from at least one of the sensors 260 and cloud data from the cloud server 130 via the cloud server interface 262. The processor 1815 receives data and/or commands from messages received from one or more of network devices 220, a user through an intelligent device, and the cloud server 130. Further, the processor 1815 composes messages to one or more of the user through the intelligent device, the user computer, the cloud server 130, and the network devices 220, where the messages are based at least in part on at least one of the sensor data, the cloud data, and the decoded messages.
The network controller 250 is further configured to transmit and receive messages via the network 200 using one or more of radio frequency (RF) communications and powerline communications.
In an embodiment, the processor 1815 sends the message to the RF transmit circuitry 1500, where the message is encoded using FSK, for example, onto a baseband signal, which is up converted and transmitted from antenna 1835 to other devices 220, 250 on the network 200. The operation of the RF transmit circuitry 1500 is described in further detail below with respect to
In addition, the antenna 1835 receives RF signals from at least one network device 220 on the network 200, which are down converted to a baseband FSK encoded signal and decoded by the RF receive circuitry 1600. The operation of the RF receive circuitry 1600 is described in further detail below with respect to
Network messages are sent over the powerline by modulating the data onto a carrier signal, which is added to the powerline signal. In an embodiment, the carrier signal is approximately 131.65 kHz. In an embodiment, the processor 1815 sends messages to the powerline transmit circuitry 800 for transmission over the network 200 via the powerline and receives data and/or commands from the network devices 220 via the powerline from the powerline receive circuitry 900. The overall flow of information related to sending and receiving messages over the network 200 via the powerline is described in further detail below with respect to
In an embodiment, the power source 1850 comprises the powerline, an AC/DC converter, and a regulator to convert and regulate the powerline voltage to approximately 5 volts to power the circuitry 262, 800, 900, 1500, 1600, 1815, 1820, and 1830. In another embodiment, the power source 1850 comprises a battery and a regulator to regulate the battery voltage to approximately 5 volts to power the circuitry 262, 800, 900, 1500, 1600, 1815, 1820, and 1830. Embodiments of the battery can be rechargeable or disposable. In other embodiments, the power source 1850 comprises other voltage sources, AC/DC converters, photovoltaic cells, electro-mechanical batteries, standard on-time use batteries, and the like.
At step 2205, the network controller stores at least one of the received and decoded messages from the network devices 220 on the network 200. The stored messages comprise past messages.
At step 2206, the network controller 250 analyzes the sensor data and the past messages. In another embodiment, the network controller 250 analyzes at least one of the sensor data, the past messages, and the cloud data. In an embodiment, the network controller 250 determines repetitive patterns, user patterns, historical patterns from one or more of the past messages. In an embodiment, the network controller 250 determines repetitive patterns, user patterns, historical patterns from one or more of the past messages in view of the sensor data and/or the cloud data. For example, the analyzed data could indicate that the user activates the network device 250 when a specific temperature or temperature range is reached, at a specific time of day, when another network device 250 attains a state or condition, or the like.
At step 2208, the network controller 250 determines whether to take an action to control a device on the network 200 based at least in part on the analysis. In an embodiment, the analysis comprises an adaptive learning process based at least in part on one or more of the sensor data, the past messages, and the cloud data. In another embodiment, based at least on the past message data, a past or historical user input to one network device 250 can be used to control another network device 250 on the home-control network 200. If no action is determined, the process 2200 returns to step 2202.
If an action is determined, the process 2200 moves to step 2210, where a message is sent to the user associated with the network 200. In an embodiment, the user is contacted via one or more of text message, social media message, email, telephone call, voice mail, and the like. In an embodiment, sending a message to the user is optional. In an embodiment, the message requests confirmation from the user before the action is taken. In another embodiment, the message is sent to the user after the action is taken to report the action.
At step 2212, the network controller 250 sends the message to the network device 220 on the network 200 to control the network device 220. In an embodiment, the message comprises a command, which is received and acted upon by the network device 220.
In an embodiment, the network controller 250 receives user actions performed on the local network 200 and continuously aggregates the network device actions. From the aggregate of the device actions, the network controller 250 creates snapshot behaviors and continuously updates the snapshots. Also, from the aggregate of the actions, the network controller 250 creates learned sequences and continuously updates the sequences.
For example, if aggregate actions indicate that the hot tub heater is set to 100° C. fifteen minutes after the front door opens on sunny weekday afternoons, then the network controller 250 can send commands to the hot tub heater to turn on and set the water temperature to 100° C. when the weather is sunny, it is a weekday, and the user's smartphone is within a specified geo-fencing ring. In addition, the network controller 250 can implement load-shedding behavior based on utility rates or a user set sliding scale between comfort and economy.
In a further embodiment, the network controller 250 receives the outside temperature from the temperature sensor 260 and determines that due to the outside air temperature, it will take longer to heat the hot tub to 100° C. The network controller 250 considers the additional heating time and sends commands to the hot-tub heater to turn on when the user's smartphone is within a different geo-fencing ring.
For example, the network controller 250 receives messages from the thermostat 220THERM, the temperature sensor 260, and the leak detector 220LEAK indicating that the house temperature setting is 35° C., the outside temperature is 27° C. and dropping, but no leaks are detected. The network controller 250 analyzes the sensor and device data and determines that the pipes are in danger of freezing and bursting.
For example, the network controller 250 receives messages from the alarm system 220ALARM, and the door lock controller 220DOOR, in addition to the thermostat 220THERM, the leak detector 220LEAK, and the temperature sensor 260. The alarm system 220ALARM and the door lock controller 220DOOR indicate that the alarm is set and the door is locked. The network controller 250 analyzes the sensor and device data and determines that the pipes are in danger of freezing and bursting, and that the homeowner has left. The network controller 250 notifies the homeowner that the home-control network 200 will drain the pipes within 2 hours unless the homeowner instructs otherwise. The network controller 250 may actively send a message to the homeowner via email, text message, or voice mail, or may passively update the status of the home-control network 250.
At step 2308, the network controller 250 determines whether the water valve is open, based at least in part on the received water valve status from the water valve controller 220WATER. If the water valve is open, the process 2300 moves to step 2310, where the network controller 250 determines whether a leak is detected based at least in part on the status of the leak detector 220LEAK.
If a leak is detected, the process moves to step 2314, where the network controller 250 determines whether the temperature is below freezing based at least in part on the received temperature sensor data. If the temperature is below freezing, the process moves to step 2316.
At step 2316, the network controller 250 sends a message to the user associated with the network 200. In an embodiment, the user is contacted via one or more of text message, social media message, email, telephone call, voice mail, and the like. In an embodiment, sending a message to the user is optional. In an embodiment, the message requests confirmation from the user before the action is taken. In another embodiment, the message is sent to the user to report the action after the action is taken.
At step 2318, the network controller 250 sends the message to the water valve controller 220WATER on the network 200 to open the water valve, such that the water pipes drain and are prevented from freezing and bursting. In an embodiment, the message comprises a command, which is received and acted upon by the water valve controller 220WATER.
If any of the conditions do not occur, such as the water valve is already open, a leak is not detected, and the temperature is above freezing, the network controller 250 performs a different analysis or rule set at step 2312.
The above scenarios comprise examples of network controller adaptive learning and are not limiting.
Typically, the network devices 220 are configured to perform an operation that affects the state of a mechanism. These operations can also be performed by the user. For example, the door lock controller 220DOOR locks and unlocks a door and the thermostat 220THERM sets the temperature on the thermostat. The user can override the action of the network device 220. For example, the user can manually unlock a door recently locked by the door controller 220DOOR and the user can manually set the thermostat to a desired temperature, overriding any temperature commands received by the thermostat 220THERM.
In an embodiment, the network device 220 on the home-control network 200 receives inputs from sensors and physical actions from the user and determines whether to change the state of the operational mechanism associated with the network device 220.
In an embodiment, the network device 220 receives user actions performed on the network device 220 and continuously aggregates the network device's actions.

The sensors 266 are configured to provide sensor data to the network device 220. In an embodiment, the sensors 266 provide sensor data to a sensor input of the network device 220. Examples of sensors 266 are one or more of a temperature sensor, a motion sensor, a light detector, a soil moisture sensor, a rain gauges, a snow gauge, a gas sensor, a flow meter, a wind meter, and the like.

At step 2403, the network device 220 receives messages from network devices 250 on the home-control network 250. In an embodiment, the network device stores at least one of the received messages from the other network devices 250. The stored messages comprise past messages. In an embodiment, the network device 250 aggregates the past messages to determine repetitive patterns, historical patterns, user patterns, or the like.
At step 2404, the network device 220 receives manual actions performed by the user. In an embodiment, the network device 220 aggregates the user's actions.

In an embodiment, the network device 220 determines repetitive patterns, user patterns, historical patterns from the past user actions. In another embodiment, the network device 220 determines repetitive patterns, user patterns, historical patterns from one or more of the past user actions and the past messages, in view of the sensor data. For example, the analyzed data could indicate that the user activates the network device 250 when a specific temperature or temperature range is reached, at a specific time of day, when another network device 250 attains a state or condition, or the like.
At step 2408, the network device 220 determines whether to take an action based at least in part on the analysis. In an embodiment, the analysis comprises an adaptive learning process based at least in part on one or more of the sensor data, the past messages, and the past user actions. In another embodiment, based at least on the past message data, a past or historical user input to one network device 250 can be used to control another network device 250 on the home-control network 200. If no action is determined, the process 2400 returns to step 2402.
If an action is determined, the process 2400 moves to step 2410, where the network device 220 performs the action to the operational mechanism 266. In an embodiment, the network device 220 reports the action to the network controller 250, which may in turn report the action to the cloud server 130 and to the user via the cloud server 130.
For example, a water valve controller 220WATER on the home-control network 200 receives sensor input and manual actions by the user and learns that Sunday evenings when the outside temperature is below 35° C., the water valve is manually closed. The water valve controller 220WATER determines based on past actions and input from a temperature sensor whether the valve should be automatically closed.
For example, in an embodiment where the leak sensor 220LEAK comprises a water valve, when the leak sensor 220LEAK detects a leak, the leak sensor 220LEAK closes the water valve.
For example, the water valve controller 220WATER on the home-control network 200 receives messages over the home-control network 200 from the leak detector 220LEAK and sensor input from a flow rate sensor. Once a leak is detected, the water valve controller 220WATER determines whether to shut the water valve immediately or to notify the user based at least in part on the flow rate sensor data.

At step 2510, the water valve controller 220WATER analyzes the past occurrences with respect to day of the week and temperature. In an embodiment, the analysis determines repetitive patterns or historical patterns with respect the day of the week and temperature, for example.
At step 2512, the water valve controller 220WATER determines whether the current day from the internal calendar is the same as the day of the past water valve closures. If the current day is the same day as the past water valve closures, the process 2500 moves to step 2516.
At step 2516, the water valve controller 220WATER determines whether the current temperature from the temperature sensor 296 is the same as the temperature during past water valve closures. If the temperature is the same as the temperature from the past water valve closures, the process 2500 moves to step 2518, where the water valve controller 220WATER determines whether the water valve 294 is open based at least in part on the valve state sensor 296. If the water valve 294 is open, the process 2500 moves to step 2520, where the water valve controller 220WATER closes the water valve 294.
If any of the conditions do not occur, such as the water valve 294 is already closed, the temperature is not approximately the same as the manual valve closure temperature, and the day is not the same as the manual valve closure day, the water valve controller 220WATER performs a different analysis or rule set 1829 at step 2514.

In an embodiment, the network 200 comprises a dual-band mesh area networking topology to communicate with devices 220 located within the network 200. In an embodiment, the network 200 comprises an INSTEON® network utilizing an INSTEON® engine employing a powerline protocol and an RF protocol. The network devices 220 can comprise, for example, light switches, thermostats, motion sensors, and the like.

Electrical power is most commonly distributed to buildings and homes in North America as single split-phase alternating current. At the main junction box to the building, the three-wire single-phase distribution system is split into two two-wire 110 VAC powerlines, known as Phase 1 and Phase 2. Phase 1 wiring is typically used for half the circuits in the building and Phase 2 is used for the other half. In the exemplary network 200, network devices 220a-220e are connected to a Phase 1 powerline 210 and network devices 220f-220h are connected to a Phase 2 powerline 228.
In the network 200, network device 220a is configured to communicate over the powerline; network device 220h is configured to communicate via RF; and network devices 220b-220g are configured to communicate over the powerline and via RF. Additionally network device 220b can be configured to communicate to the network controller or hub 250 and the network controller or hub 250 can be configured to communicate with the computer 230 and other digital equipment using, for example, RS232, USB, IEEE 802.3, or Ethernet protocols and communication hardware. The network controller or hub 250 on the network 200 communicating with the computer 230 and other digital devices can, for example, bridge to networks of otherwise incompatible devices in a building, connect to computers, act as nodes on a local-area network (LAN), or get onto the global Internet. In an embodiment, the computer 230 comprises a personal computer, a laptop, a tablet, a smartphone, or the like, and interfaces with a user. The network controller or hub 250 can further be configured to provide information to a user through the computer 230.
In an embodiment, network devices 220a-220g that send and receive messages over the powerline use the INSTEON® Powerline protocol, and network devices 220b-220h that send and receive radio frequency (RF) messages use the INSTEON® RF protocol, as defined in U.S. Pat. Nos. 7,345,998 and 8,081,649 which are hereby incorporated by reference herein in their entireties. INSTEON® is a trademark of the applicant.
Network devices 220b-220h that use multiple media or layers solve a significant problem experienced by devices that only communicate via the powerline, such as network device 220a, or by devices that only communicate via RF, such as network device 220h. Powerline signals on opposite powerline phases 210 and 228 are severely attenuated because there is no direct circuit connection for them to travel. RF barriers can prevent direct RF communication between devices RF only devices. Using devices capable of communicating over two or more of the communication layers solves the powerline phase coupling problem whenever such devices are connected on opposite powerline phases and solves problems with RF barriers between RF devices. Thus, within the network 200, the powerline layer assists the RF layer, and the RF layer assists the powerline layer.
As shown in
Each network device 220a-220h is configured to repeat messages to others of the network devices 220a-220h on the network 200. In an embodiment, each network device 220a-220h is capable of repeating messages, using the protocols as described herein. Further, the network devices 220a-220h are peers, meaning that any device can act as a master (sending messages), slave (receiving messages), or repeater (relaying messages). Adding more devices configured to communicate over more than one physical layer increases the number of available pathways for messages to travel. Path diversity results in a higher probability that a message will arrive at its intended destination.
For example, RF network device 220d desires to send a message to network device 220e, but network device 220e is out of range. The message will still get through, however, because devices within range of network device 220d, such as network devices 220a-220c will receive the message and repeat it to other devices within their respective ranges. There are many ways for a message to travel: network device 220d to 220c to 220e (2 hops), network device 220d to 220a to 220c to 220e (3 hops), network device 220d to 220b to 220a to 220c to 220e (4 hops) are some examples.
Unless there is a limit on the number of hops that a message may take to reach its final destination, messages might propagate forever within the network 200 in a nested series of recurring loops. Network saturation by repeating messages is known as a “data storm.” The message protocol avoids this problem by limiting the maximum number of hops an individual message may take to some small number. In an embodiment, messages can be retransmitted a maximum of three times. In other embodiments, the number of times a message can be retransmitted is less than 3. In further embodiments, the number of times a message can be retransmitted is greater than 3. The larger the number of retransmissions, however, the longer the message will take to complete.
Embodiments comprise a pattern of transmissions, retransmissions, and acknowledgements that occurs when messages are sent. Message fields, such as Max Hops and Hops Left manage message retransmission. In an embodiment, messages originate with the 2-bit Max Hops field set to a value of 0, 1, 2, or 3, and the 2-bit Hops Left field set to the same value. A Max Hops value of zero tells other network devices 220 within range not to retransmit the message. A higher Max Hops value tells network devices 220 receiving the message to retransmit it depending on the Hops Left field. If the Hops Left value is one or more, the receiving device 220 decrements the Hops Left value by one and retransmits the message with the new Hops Left value. Network devices 220 that receive a message with a Hops Left value of zero will not retransmit that message. Also, the network device 220 that is the intended recipient of a message will not retransmit the message, regardless of the Hops Left value.
In other words, Max Hops is the maximum retransmissions allowed. All messages “hop” at least once, so the value in the Max Hops field is one less than the number of times a message actually hops from one device to another. In embodiments where the maximum value in this field is three, there can be four actual hops, comprising the original transmission and three retransmissions. Four hops can span a chain of five devices. This situation is shown schematically in
At step 415, the process 400 determines whether the network device 220 needs to process the received message. The network device 220 processes Direct messages when the network device 220 is the addressee, processes Group Broadcast messages when the network device 220 is a member of the group, and processes all Broadcast messages.
If the received message is a Direct message intended for the network device 220, a Group Broadcast message where the network device 220 is a group member, or a Broadcast message, the process 400 moves to step 440. At step 440, the network device 220 processes the received message.
At step 445, the process 400 determines whether the received message is a Group Broadcast message or one of a Direct message and Direct group-cleanup message. If the message is a Direct or Direct Group-cleanup message, the process moves to step 450. At step 450, the device sends an acknowledge (ACK) or a negative acknowledge (NAK) message back to the message originator in step 450 and ends the task at step 455.
In an embodiment, the process 400 simultaneously sends the ACK/NAK message over the powerline and via RF. In another embodiment, the process 400 intelligently selects which physical layer (powerline, RF) to use for ACK/NAK message transmission. In a further embodiment, the process 400 sequentially sends the ACK/NAK message using a different physical layer for each subsequent retransmission.
If at step 445, the process 400 determines that the message is a Broadcast or Group Broadcast message, the process 400 moves to step 420. If, at step 415, the process 400 determines that the network device 220 does not need to process the received message, the process 400 also moves to step 420. At step 420, the process 400 determines whether the message should be retransmitted.
At step 420, the Max Hops bit field of the Message Flags byte is tested. If the Max Hops value is zero, process 400 moves to step 455, where it is finished. If the Max Hops filed is not zero, the process 400 moves to step 425, where the Hops Left filed is tested.
If there are zero Hops Left, the process 400 moves to step 455, where it is finished. If the Hops Left field is not zero, the process 400 moves to step 430, where the process 400 decrements the Hops Left value by one.
At step 435, the process 400 retransmits the message. In an embodiment, the process 400 simultaneously retransmits the message over the powerline and via RF. In another embodiment, the process 400 intelligently selects which physical layer (PL, RF) to use for message retransmission. In a further embodiment, the process 400 sequentially retransmits the message using a different physical layer for each subsequent retransmission.
Following the Group Broadcast message, the transmitting device 220 sends a Direct Group-cleanup message individually to each member of the group in its database. At step 515, the network device 220 first sets the message To Address to that of the first member of the group, then it sends a Direct Group-cleanup message to that addressee at step 520. If Group-cleanup messages have been sent to every member of the group, as determined at step 525, transmission is finished at step 535. Otherwise, the network device 220 sets the message To Address to that of the next member of the group and sends the next Group-cleanup message to that addressee at step 520.
At step 615, the network device 220 sends a Direct or a Direct Group-cleanup message to an addressee. At step 620, the network device 220 waits for an Acknowledge message from the addressee. If, at step 625, an Acknowledge message is received and it contains an ACK with the expected status, the process 600 is finished at step 645.
If, at step 625, an Acknowledge message is not received, or if it is not satisfactory, a Retry Counter is tested at step 630. If the maximum number of retries has already been attempted, the process 600 fails at step 645. In an embodiment, network devices 220 default to a maximum number of retries of five. If fewer than five retries have been tried at step 630, the network device 220 increments its Retry Counter at step 635. At step 640, the network device 220 will also increment the Max Hops field in the Message Flags byte, up to a maximum of three, in an attempt to achieve greater range for the message by retransmitting it more times by more network devices 220. The message is sent again at step 615.
The network devices 220 comprise hardware and firmware that enable the network devices 220 to send and receive messages.
To send a message, the application places message data in a buffer 745, then tells the message controller 750 to send the message using the control flags 755. Message transmitter 740 processes the message into a raw bitstream, which it feeds to a modem transmitter 735. The modem transmitter 735 sends the bitstream as a powerline signal, a radio frequency signal, or both.
As the message data is shifted out of FIFO transmit buffer 815, the CRC generator 830 calculates the CRC byte, which is appended to the bitstream by the multiplexer 835 as the last byte in the last packet of the message. The bitstream is buffered in a shift register 840 and clocked out in phase with the powerline zero crossings detected by zero crossing detector 845. The phase shift keying (PSK) modulator 855 shifts the phase of an approximately 131.65 kHz carrier signal from carrier generator 850 by approximately 180 degrees for zero-bits, and leaves the carrier signal unmodulated for one-bits. In other embodiments, the carrier signal can be greater than or less than approximately 131.65 kHz. Note that the phase is shifted gradually over one carrier period as disclosed in conjunction with
Whether it is phase-locked or not, the Costas PLL 920 sends data to the bit sync detector 930. When the sync bits of alternating ones and zeroes at the beginning of a packet arrive, the bit sync detector 930 will be able to recover a bit clock, which it uses to shift data into data shift register 935. The start code detector 940 looks for the start code following the sync bits and outputs a detect signal to the window timer 945 after it has found one. The window timer 945 determines that a valid packet is being received when the data stream begins approximately 800 microseconds before the powerline zero crossing, the phase lock detector 925 indicates lock, and detector 940 has found a valid start code. At that point the window timer 945 sets a start detect flag 990 and enables the receive buffer controller 955 to begin accumulating packet data from shift register 935 into the FIFO receive buffer 960. The storage controller 955 insures that the FIFO 960 builds up the data bytes in a message, and not sync bits or start codes. It stores the correct number of bytes, 10 for a standard message and 24 for an extended message, for example, by inspecting the Extended Message bit in the Message Flags byte. When the correct number of bytes has been accumulated, a HaveMsg flag 965 is set to indicate a message has been received.
Costas PLLs have a phase ambiguity of 180 degrees, since they can lock to a signal equally well in phase or anti-phase. Therefore, the detected data from PLL 920 may be inverted from its true sense. The start code detector 940 resolves the ambiguity by looking for the true start code, C3 hexadecimal, and its complement, 3C hexadecimal. If it finds the complement, the PLL is locked in antiphase and the data bits are inverted. A signal from the start code detector 940 tells the data complementer 970 whether to un-invert the data or not. The CRC checker 975 computes a CRC on the received data and compares it to the CRC in the received message. If they match, the CRC OK flag 980 is set.
Data from the complementer 970 flows into an application buffer, not shown, via path 985. The application will have received a valid message when the HaveMsg flag 965 and the CRC OK flag 980 are both set.
In an embodiment, the powerline packets comprise 24 bits. Since a bit takes ten cycles of 131.65 kHz carrier, there are 240 cycles of carrier in a packet, meaning that a packet lasts approximately 1.823 milliseconds. The powerline environment is notorious for uncontrolled noise, especially high-amplitude spikes caused by motors, dimmers, and compact fluorescent lighting. This noise is minimal during the time that the current on the powerline reverses direction, a time known as the powerline zero crossing. Therefore, the packets are transmitted near the zero crossing.
In some embodiments, the powerline transmission process waits for one or two additional zero crossings after sending a message to allow time for potential RF retransmission of the message by network devices 220.
In some embodiments, standard messages contain 120 raw data bits and use six zero crossings, and take approximately 50 milliseconds to send. In some embodiments, extended messages contain 264 raw data bits and use thirteen zero crossings, and take approximately 108.33 milliseconds to send. Therefore, the actual raw bitrate is approximately 2,400 bits per second for standard messages 1310, and approximately 2,437 bits per second for extended messages 1430, instead of the 2880 bits per second the bitrate would be without waiting for the extra zero crossings 1320, 1440.
In some embodiments, standard messages contain 9 bytes (72 bits) of usable data, not counting packet sync and start code bytes, and not counting the message CRC byte. In some embodiments, extended messages contain 23 bytes (184 bits) of usable data using the same criteria. Therefore, the bitrates for usable data are further reduced to 1440 bits per second for standard messages 1310 and 1698 bits per second for extended messages 1430. Counting only the 14 bytes (112 bits) of User Data in extended messages, the User Data bitrate is 1034 bits per second.
The network devices 220 can send and receive the same messages that appear on the powerline using radio frequency signaling. Unlike powerline messages, however, messages sent by radio frequency are not broken up into smaller packets sent at powerline zero crossings, but instead are sent whole. As with powerline, in an embodiment, there are two radio frequency message lengths: standard 10-byte messages and extended 24-byte messages.
The steps are similar to those for sending powerline messages in
As the message data is shifted out of FIFO 1515, the CRC generator 1530 calculates the CRC byte, which is appended to the bitstream by the multiplexer 1535 as the last byte of the message. The bitstream is buffered in the shift register 1540 and clocked out to the RF transceiver 1555. The RF transceiver 1555 generates an RF carrier, translates the bits in the message into Manchester-encoded symbols, frequency modulates the carrier with the symbol stream, and transmits the resulting RF signal using antenna 1560. In an embodiment, the RF transceiver 1555 is a single-chip hardware device and the other steps in
The steps are similar to those for receiving powerline messages given in
The start code detector 1625 looks for the start code following the sync bits at the beginning of the message and outputs a detect signal 1660 to the processor 1665 after it has found one. The start detect flag 1660 enables the receive buffer controller 1630 to begin accumulating message data from shift register 1620 into the FIFO receive buffer 1635. The storage controller 1630 insures that the FIFO receive buffer 1635 stores the data bytes in a message, and not the sync bits or start code. In an embodiment, the storage controller 1630 stores 10 bytes for a standard message and 24 for an extended message, by inspecting the Extended Message bit in the Message Flags byte.
When the correct number of bytes has been accumulated, a HaveMsg flag 1655 is set to indicate a message has been received. The CRC checker 1640 computes a CRC on the received data and compares it to the CRC in the received message. If they match, the CRC OK flag 1645 is set. When the HaveMsg flag 1655 and the CRC OK flag 1645 are both set, the message data is ready to be sent to processor 1665. In an embodiment, the RF transceiver 1615 is a single-chip hardware device and the other steps in
Symbols are modulated onto the carrier using frequency-shift keying (FSK), where a zero-symbol modulates the carrier by half of the FSK deviation frequency downward and a one-symbol modulates the carrier by half of the FSK deviation frequency upward.

Thus, such conditional language is not generally intended to imply that features, elements and/or states are in any way required for one or more embodiments or that one or more embodiments necessarily include logic for deciding, with or without author input or prompting, whether these features, elements and/or states are included or are to be performed in any particular embodiment.
The above detailed description of certain embodiments is not intended to be exhaustive or to limit the invention to the precise form disclosed above. While specific embodiments of, and examples for, the invention are described above for illustrative purposes, various equivalent modifications are possible within the scope of the invention, as those ordinary skilled in the relevant art will recognize. For example, while processes, steps, or blocks are presented in a given order, alternative embodiments may perform routines having steps, or employ systems having blocks, in a different order, and some processes, steps, or blocks may be deleted, moved, added, subdivided, combined, and/or modified. Each of these processes, steps, or blocks may be implemented in a variety of different ways. Also, while processes, steps, or blocks are at times shown as being performed in series, these processes, steps, or blocks may instead be performed in parallel, or may be performed at different times.
The teachings of the invention provided herein can be applied to other systems, not necessarily the systems described above. The elements and acts of the various embodiments described above can be combined to provide further embodiments.
While certain embodiments of the inventions have been described, these embodiments have been presented by way of example only, and are not intended to limit the scope of the disclosure.
