DETAILED DESCRIPTION OF THE INVENTION

The following will describe embodiments of the invention together with the accompanying drawings and each embodiment can be implemented. Besides, the well known details will not be given hereinafter to prevent from blurring the key of the invention. Each embodiment does not need to be excluded from others and can combine with other embodiment(s) to comprise one embodiment of the invention. The following will describe a number of embodiments of the invention and various modifications or changes can be made by those who are skilled in the art without deviating from the spirit of the invention. The invention should not be restricted into the following embodiments or the characteristics described in the following.

The present invention discloses a device and method for appliance usage scheduling and control using an on-line calendar service with an open API. The following embodiments use a google on-line calendar with open API as examples but the present invention is not limited to these examples. Various current on-line calendars with open APIs or on-line calendars with open APIs to be developed in the future are applicable to the techniques of the invention.

FIG. 1 shows a schematic diagram illustrating a device for appliance usage scheduling and control using an on-line calendar service with an open API according to one embodiment of the invention. The device 100 includes a calculator 102, a google calendar 101 with an open API, a home automation server 103, and a local network 104.

The calculator 102 includes a user interface and a checking procedure. A user may set data of a schedule as an event E in the google calendar to control electronic appliances. The event E may comprise one of the following or combination thereof: date, time, which device to be controlled, setting data of a signal.

The checking procedure may generate an inquiry data AE to ask the google calendar for events of home automation control. The checking procedure may receive an event data packet D from the google calendar. It should be noted that in one embodiment, the user interface can simultaneously operate with two or more than two calendars with open APIs.

A user may operate the calculator 102 to set a schedule including at least an event for home automation. The calculator 102 then generates an event E to the google calendar 101 with an open API. Further, the google calendar 101 generates the event data packet D according to the event E corresponding to the request of the user.

In one embodiment, the home automation server 103 receives at least a control signal C event data packet via a network event data packet. In one embodiment, the checking procedure of calculator 102 generates the control signal C according to the event data packet D. Then the home automation server 103 transmits the control signal C to the local network 104. In another embodiment, the home automation server 103 may receive and process the event data packet D to generate the control signal Cevent data packet directly through the google calendar 101.

The local network 104 may communicate with at least an electronic appliance 105 (105a˜105b) or control the operation of the device (electronic appliance) 105 (105a˜105b) according to the control signal C by a wired or wireless method. For example, the devices may be examples: the light source 105a, the TV set 105b and the fan 105c as shown in FIG. 1. The network 104 may communicate with or control at least an electronic appliance 105 through RF (radio frequency) transmission channel as shown in FIG. 1. As shown in FIG. 2A, the local network 104 may be a sensor network, such as an ECO sensor network (it should be noted that ECO is a wireless sensor platform developed by the applicant himself where ECO is the exact word but not abbreviation). The sensor network 104 includes a plurality of sensors. The sensors, coupled the electronic appliances, communicates with the home automation server through RF channel. The sensors provide the operation state of the electronic appliances to the home automation server 103 or receive signals from the home automation server 103 to execute operations in the schedule, such as turning on/off or controlling the electronic appliance (for example, various operations like adjusting the magnitude of the electric energy, controlling the fan to rotate slower or faster, etc.).

The home automation server may be a e butler server. In one embodiment, the home automation server may be implemented on a microcontroller evaluation board having a serial peripheral interface (SPI), such as Freescale M52259DEMOKIT, shown in FIG. 2B. The home automation server is not limited to be the microcontroller evaluation board having a serial peripheral interface (SPI) from Freescale. The home automation server may also be an embedded system development kit from other companies. As long as the embedded system development kit has a serial peripheral interface (SPI) and supports a network function, the system of the invention can be implemented thereon. That is, the invention can be implemented on any current embedded system or any embedded system to be developed in the future.

The e butler server uses a polling mechanism to constantly check if any event is triggered in the schedule of google calendar. If the e butler server receives the event data packet D from the network, it indicates an event is triggered and then the control module of the e butler server is initiated according to the event data packet D. Further, the e butler server generates at least a control signal C to communicate with or control the sensor through RF, thereby controlling functions of the electronic appliance. Thus the operation of each electronic appliance can be controlled according to the schedule on the on-line calendar.

As shown in FIG. 2B, the e butler server includes a network connector 103a and a signal transmission connector 103b. The network connector may be an Ethernet connector RJ45, . . . any current or future developed data transmission connector. The signal transmission connector 103b, coupled to the calculator 102, may be a universal serial bus RS232, any current or future developed signal transmission connector.

It should be noted that the home automation server 103 and the sensor network 104 may be integrated into a product. Further, the event data packet D may be transmitted to the home automation server 103 through one of the following or combination thereof: personal computer PC and google calendar 101.

Please refer to FIG. 3A and FIG. 3B. FIG. 3A shows a schematic diagram illustrating an application example for appliance usage scheduling using an on-line calendar service with an open API. FIG. 3B shows a schematic diagram illustrating an example schedule Sc set by a user.

At first, it is assumed that “schedule start time” is the time turning on an electronic appliance and “schedule end time” is the time turning off the electronic appliance. A user may be informed of and control the setting of each electronic appliance by the display of the schedule Sc. Thus a user may remotely control the current state of each electronic appliance.

For example, as shown in FIG. 3A, users P1 and P2 separately use a calculator (such as a personal computer or a laptop computer) and a portable device C1 to communicate with the access point AP (such as IP sharing device, router, etc.) in a local network via a wired or wireless path. Then, the users P1 and P2 communicate with the home automation server 103 (e butler server) through an internet network In. Users P3 and P4 separately use the portable devices C2, C3 of different systems (such as Android system or Apple platform) to communicate with the mobile base station B in a mobile network (such as 3G network, etc.) to thereby connect to the internet network In. Thus portable devices C2, C3 may communicate with the home automation server 103. As shown in FIG. 3A, the sensors 104a, 104b, 104f are coupled to the electronic appliances 105d, 105e, 105f. Then the home automation server 103 may turn on/off the electronic appliances 105d 105e, 105f through the interior transmission base station A1 or A2 (such as wireless broadcasting base station, . . . , etc.). It should be noted that in one embodiment each of the above sensors may be a switch to control electrical power or may be other form to adjust the operation of the electronic appliance.

A scene is assumed. In a hot summer, a user comes home at 7 p.m. every day and then turns on an air conditioner and a lamp in the living room. At 9 p.m., the air conditioner is turned off and at 11 p.m. the lamp in the living room is turned off and a table lamp is turned on. At the time, the user may input data of a schedule Sc (such as set “schedule start time” of the lamp to 3:30 pm and “the schedule end time” to 7:00 pm) into the google calendar 101. Then the home automation server 103 will automatically control the switches of the electronic appliances to let the air conditioner and the lamp already turned on at the time before user arrives home. If the user has to work overtime one day and will be home very late, the user only needs to use his mobile phone to connect to internet to delete the schedule of turning on the air conditioner and the lamp or to postpone the schedule.

It should be noted that according to one embodiment of the invention the user may set a schedule of any day or days within one year and the format of the schedule Sc may be adjusted according to the designer or needs of the user.
