The present disclosure relates generally to light-emitting diode (LED) lamps, and more particularly to a smart lamp system and method for monitoring a status of LEDs in flasher lamps.
Railway crossings are instrumental for interfacing railroads and vehicle crossings. The railway crossings provide safety for all parties involved by signaling to any motorists or pedestrians when a train is approaching the railway crossing. The Federal Railway Act (FRA) governs the minimum requirements for the railway crossing to be considered safe for the public. For example, the FRA requires the railway crossing to include greater than 50% of the lights on a mast at the railway crossing to be operational, otherwise the railway crossing fails the FRA requirements and the railway organization may be subject to any applicable fines. Several approaches exist for managing the lights along the railway crossings. For example, a current method is to use incandescent lights to illuminate the crossing. While the incandescent light can allow a technician to remotely monitor the status of the light operations, the incandescent lights are inefficient and consume vast power. Alternatively, another current method is to use LEDs. The LEDs are more energy efficient, but the limiting effect of the marginal power consumption impede the technician's ability to identify when a strip of LEDs is non-operational.
Regarding incandescent lights, the traditional incandescent crossing flashers utilize a light-out detection device (LOD) equipped with an amperage clamp that effectively measures current draw upon activation. The LOD devices available today are ineffective with LED lamps as the current draw needed to illuminate the LED nodes is much lower than the current draw needed to illuminate an incandescent bulb. Various attempts have been made to retrofit LOD devices with LED flashers with unfavorable results.
While incandescent bulbs when paired with an LOD device provide increased monitoring of a railway crossing's operation, LED lamps provide greater visibility to motorists and pedestrians approaching a highway-rail grade crossing and are favorable to use for railway crossings. Additionally, LED lamps do not utilize a filament for operation effectively providing greater lifecycles versus traditional incandescent flasher bulbs. LED lamps are a long-term solution that provide superior lumen output over a broader focal point. Unfortunately, accurate and dependable light-out detection for LED units has not been realized.
The present disclosure achieves technical advantages as a smart lamp system and method for monitoring a status of LEDs. The system can provide LED status monitoring using a logic controller communicating with at least one strip of LEDs. The system can utilize the logic controller to assign a unique identifier (ID) to the at least one strip of LEDs based on a physical position of a plurality of dual-inline package (DIP) switches incorporated within a smart lamp housing. The system can provide a hardware architecture to interface the logic controller with a transceiver. The transceiver can provide receipt and transmission of data signals. In one embodiment, the transceiver can be a power-line communication (PLC) transceiver. In another embodiment, the same electrical wires used to power the smart lamp are used for communicating the statuses of the LEDs between the logic controller and the PLC transceiver. The system can establish a communication protocol between the PLC transceiver and a PLC receiver to efficiently communicate the statuses of the LEDs. For example, in response to a triggering event, the PLC transceiver can activate the logic controller to provide power to the strip of LEDs. The logic controller can generate a payload including a binary representation of the unique ID of the smart lamp and the statuses of the LEDs and transmit the payload to the PLC transceiver. The PLC transceiver can generate a message frame corresponding to the communication protocol including the payload, where the timing of the message frame can be based on a delay corresponding to the position of the DIP switches.
The present disclosure can allow the rail industry to effectively monitor the status of LED flashers without costly infrastructure changes as it will negate the need to run separate conductors from the bungalow to each crossing mast. By monitoring each flasher state, greater visibility and reduced crossing activation failures and partial activations can be achieved by proactively deploying maintenance personnel to correct any deficiencies reported by the CFMW rather than discovering issues during scheduled maintenance. The system can include a monitoring component capable of identifying whether each flasher flashes as intended, a communications component that reports status via communications over power, and a processing component that evaluates crossing flasher status and generates alarms as needed. The system will help reduce the occurrence of crossing activation failures by identifying some flasher malfunctions before multiple malfunctions combine to create an activation failure.
The present disclosure can maintain the same operating value requirements as the current options available (e.g., 9-16 VDC/VAC) which should be standardized for the internal componentry to consistently capture and report various statuses. The present disclosure can include a micro-processor-based controller (processor) installed either, within the housing of the LED flasher, or installed externally. For example, within a discreet, ruggedized housing (e.g., IP68 rated) that can attach to the two (2) non-polarity sensitive power wires, small enough to fit into the crossing flasher enclosure behind the system. In one embodiment, the micro-processor-based device can be operably coupled to a plurality of dual-inline package (DIP) switches and a micro-controller capable of various functions. In another embodiment, at least seven (7) DIP switches. The micro-controller can monitor voltage, current, and DIP switch arrangement which can establish a delay in reporting and will also relay at least the following information to a PLC device mounted within the Crossing Control House (“CCH”—hereby referred to as bungalow): DIP Switch configuration and status of 0, 1, 2, or 3. Where the statuses can indicate:
0—Both strings of LEDs inoperable (undesired state);
1—LED string A inoperable, LED string B operable (permissible state);
2—LED string A operable, LED string B inoperable (permissible state); and
3—Unit fully operational (desired state).
Accordingly, the present disclosure discloses concepts inextricably tied to computer technology such that the present disclosure provides the technological benefit of implementing power-line communications to monitor statuses of LEDs using a logic controller to generate a payload compliant with a communication protocol. The firmware of the logic controller can include custom designed firmware applications to instantiate the logic controller, control the LEDs, and efficiently time the communication between the various hardware components.
The present disclosure provides a technological solution missing from conventional systems by at least providing a method using power-line communications able to detect functionality of LEDs unseen in conventional approaches. The present disclosure transforms a physical state of the LEDs to logical values based on a state machine programmed within the logic controller corresponding to the statuses of the LEDs. The present disclosure surpasses the conventional approaches by providing an ability to monitor the statuses of LEDs previously undetectable and by providing a power consumption efficient for modern lighting solutions.

In this way, the LE circuit changes polarity, the PLC receiver 140 can include terminal connections that are not polarity sensitive.
In another example, the PLC receiver 140 can correspond to a web-based graphical user interface (web GUI) allowing a technician to configure and customize the system 100 to match the application. For example, the system 100 is exemplary and can extrapolate to any number of PLC transceivers and LED strips. For example, the system 100 can illuminate a railway crossing with two smart lamps (e.g., the system 100) and the web GUI can allocate the unique IDs of the DIP switches to the PLC receiver 140 such that the PLC receiver 140 can communicate with the PLC transceivers. In an example, the web GUI can include both configurable labels (i.e. left/right) and fixed objects that are non-configurable, that can be selected (i.e. front/rear). In an example, if an object is selected, a label should be attached. In an example, the PLC receiver 140 can include the mast inputs 142a-142b. The mast inputs 142a-142b, in an embodiment, can interface the terminals 138a-138c to the PLC receiver 140.

The LED identification module 210, in an embodiment, can identify a particular LED strip of the smart lamp. For example, the LED identification module 210 can identify the LED strip based on an LED ID corresponding to each of the LED strips. In an example, the LED identification module 210 can include LED information corresponding to the LEDs present in the smart lamp. The LED identification module 210 can compare input signals from the LEDs to the LED information to identify the LED strips.

In one embodiment, the DIP switch system 304 can include the switch identification module 216, the switch update module 218, and the switch reset module 220. The LED reset module 214, the switch identification module 216, and the switch update module 218 can implement one or more algorithms to determine a state of a plurality of DIP switches in response to communicating information between the smart lamp system 300 and a PLC receiver. The algorithms and their associated thresholds and/or signatures can be programmable to uniquely suit a particular application for a plurality of smart lamps. The DIP switch system 304 can be configured to transmit and receive messages related to DIP switch positions, updates, and states from the PLC interface system 306.
The switch identification module 216, in an embodiment, can identify a current state of the DIP switches. For example, the DIP switches can correspond to various states relating to a position of the smart lamp system 300. In an example, the DIP switches can generate an electrical signal based on a mechanical position of the DIP switches, relating to the position of the smart lamp system 300. For example, when the smart lamp system 300 is positioned adjacent to another smart lamp system, the DIP switches can include a configuration representing the relative positions of the DIP switches. In an example, the DIP switches can indicate whether the smart lamp system 300 is to the left or to the right of a common reference position. The DIP switches can represent the position of the smart lamp system 300 by a position of one of the DIP switches. For example, when the smart lamp system 300 is on the left of the common reference position, one of the DIP switches can be in an up state, represented as a binary “1” in the corresponding electrical signal.
The switch update module 218, in an embodiment, can identify when an update to an arrangement of the DIP switches occurs. For example, the DIP switches can change based on an external input, such as a technician physically flipping the DIP switch. In this way, the switch update module 218 can identify when the change occurs to the DIP switches by comparing a prior state of the DIP switches with a current state of the DIP switches. In an example, the prior state of the DIP switches can be included in local memory such that it can be stored indefinitely. For example, when the smart lamp system 300 resets, compatibility between the DIP switches and the prior state can be maintained. Alternatively, when the DIP switches change, the prior state can update to a new configuration and store the current state in local memory.
The switch reset module 220, in an embodiment, can reset any stored DIP switch arrangement. For example, when the DIP switches shift the mechanical positions causing the electrical signal to include inconsistent values, the switch reset module 220 can clear any stored DIP switch arrangement such that there is no ambiguity.

The PLC status module 222, in an embodiment, can identify a status of a PLC receiver. For example, the PLC receiver can be disconnected from the smart lamp system 300, resulting in no power-line communications transmitted to the smart lamp system 300. In this way, the PLC status module 222 can identify the PLC receiver is inoperable. In another example, the PLC status module 222 can identify when the PLC receiver is capable of receiving a data transmission. For example, the PLC receiver can receive data transmission when the crossing relay is active. The PLC receiver can generate a notification to the PLC status module 222 to enable communications between the two components. The PLC status module 222 can receive the notification from the PLC receiver and begin the data communication process.
The characteristics monitoring module 224, in an embodiment, can monitor various characteristics of the smart lamp system 300. For example, the characteristics monitoring module 224 can monitor voltage, current, and DIP switch arrangement of the smart lamp system 300. In an example, the characteristics monitoring module 224 can identify a value of the voltage based on power-line transmission between the PLC interface system 306 and the PLC receiver. In an example, the characteristics monitoring module 224 can assign a smart lamp configuration based on the DIP switch arrangement. For example, the DIP switch arrangement can correspond with a physical position of the smart lamp system 300 in relation to other smart lamps. In an example, the DIP switch arrangement can include a DIP switch position indicating a position of the smart lamp relative to a reference point. For example, the DIP switch position can indicate the smart lamp is to the left of the reference point, or to the right of the reference point based on the DIP switch position being up or down, respectively. The characteristics monitoring module 224 can identify a value of the current based on power-line transmission between the PLC interface system 306 and the PLC receiver. The characteristics monitoring module 224 can identify positions of the DIP switches based on the electrical signal from the DIP switches. The electrical signal can include binary representation of the positions of the DIP switches.
In another example, the characteristics monitoring module 224 can detect an activation failure. For example, the characteristics monitoring module 224 can identify a number of operational LED strips. In an example, when the number of the operational LED strips is below a threshold the characteristics monitoring can generate an alert as the activation failure. The threshold can include a ratio of the operational LED strips to a total number of LED strips. In an example, the threshold can include the ratio to be 50% of the total number of LED strips are operational. The activation failure can correspond to legal compliance with regulations for public safety. For example, the activation failure can correspond to a number of operational LED strips at a railway crossing.
The communication module 226, in an embodiment, can transmit data between the PLC interface system 306 and the PLC receiver. For example, the communication module 226 can generate a communication payload organizing the DIP switch positions and the statuses of the LED strips in a binary format. The communication module 226 can transmit the data in a time duration corresponding to a particular application. For example, the communication module 226 can transmit the data in a 1-second time window. In an example, the communication module 226 can transmit lamp information. The lamp information can include the DIP switch positions and statuses of the LED strips.
In an embodiment, the smart lamp control logic 400 can include a plurality of DIP switches for representing an identifier of at least one LED strip. The smart lamp control logic 400 can interface the DIP switches with a power-line transceiver configured to transmit statuses of the at least one LED strip and DIP switch positions via power-line communications utilizing voltage feed lines powering the smart lamp. The smart lamp control logic 400 can further include a memory for storing the DIP switch positions, the statuses, and configuration enabling information. Additionally, the smart lamp control logic 400 can interface the memory with a processor that is configured to configured to monitor the statuses of the at least one LED strip. The smart lamp control logic 400 implementing hardware components (e.g., computer processor) can be capable of executing machine-readable instructions to perform program steps and operably coupled to a memory for storing the DIP switch positions, the statuses, and configuration enabling information.
The smart lamp control logic 400 can leverage the ability of a computer platform to spawn multiple processes and threads by processing data simultaneously. The speed and efficiency of the smart lamp control logic 400 can be greatly improved by instantiating more than one process for monitoring a status of LEDs. However, one skilled in the art of programming will appreciate that use of a single processing thread may also be utilized and is within the scope of the present disclosure. The smart lamp control logic 400 can also be distributed amongst a plurality of networked computer processors. The smart lamp control logic 400 of the present embodiment begins at step 402.
At step 402, in an embodiment, the control logic 400 can represent an identifier of at least one LED strip. For example, the control logic 400 can receive electrical signals corresponding to the LED strips for a smart lamp. In an example, the LEDs can correspond to a collective electrical signal transmitted to the processor at a particular voltage. The particular voltage can correspond with a manufacturer of the LEDs. For example, a first manufacturer can provide LEDs with a threshold voltage lower than LEDs from a second manufacturer. For example, the control logic 400 can identify the LED strip based on an LED ID corresponding to each of the LED strips. In an example, the control logic 400 can include LED information corresponding to the LEDs present in the smart lamp. The control logic 400 can compare input signals from the LEDs to the LED information to identify the LED strips. The control logic 400 then proceeds to step 404.
At step 404, in an embodiment, the control logic 400 can monitor the voltage, current, and DIP switch arrangement. For example, the control logic 400 can monitor voltage, current, and DIP switch arrangement of the smart lamp. In an example, the control logic 400 can identify a value of the voltage based on power-line transmission between the P control logic 400 and a PLC receiver. The control logic 400 can identify a value of the current based on power-line transmission between the control logic 400 and the PLC receiver. The control logic 400 can identify positions of the DIP switches based on the electrical signal from the DIP switches. The electrical signal can include binary representation of the positions of the DIP switches. The control logic 400 then proceeds to step 406.
At step 406, in an embodiment, the control logic 400 can generate a communications payload based on the statuses and the DIP switch positions. For example, the statuses can indicate whether a first LED strip and a second LED strip are operating normally. In an example, the statuses can indicate whether the first LED strip or the second LED strip are inoperable. In an example, the statuses can indicate whether the first LED strip and the second LED strip are inoperable. The control logic 400 can generate a communication payload based on the statuses of the first LED strip and the second LED strip. For example, the control logic 400 can include a state machine to convert the statuses to binary representation. In an example, the binary representation can be as follows.
In another example, the control logic 400 can generate a communication payload corresponding to the statuses. For example, the control logic 400 can perform various protocol actions across a time window. The protocol actions can include wakeup, delay, transmission, and silence. The wakeup action can include the control logic 400 receives power, performs self-diagnostic checks, and prepares the control logic 400 for transmitting over the power line. The delay can include activation of a communication timing delay based on a position of the DIP switches and standby to transmit a message. The transmission can include an end to the delay and the control logic 400 transmits the unique ID and the statuses. The silence can include a standby to lose power when the time window ends. The time window can include a 1 second duration. The control logic 400 then proceeds to step 408.
At step 408, in an embodiment, the control logic 400 can transmit the communications payload to the power-line transceiver. For example, the communications payload can include the unique ID, DIP switch positions, and statuses of the LED strips. The control logic 400 then proceeds to step 410.
At step 410, in an embodiment, the control logic 400 can transmit statuses of the at least one LED strip and DIP switch positions via power-line communications utilizing voltage feed lines powering a smart lamp. For example, the control logic 400 can identify the status of the LED strip based on an input from the LED strip including a binary representation of the status of the LED strip. In another example, the control logic 400 can identify a current state of the DIP switches. For example, the DIP switches can correspond to various states relating to a position of the smart lamp. In an example, the DIP switches can generate an electrical signal based on a mechanical position of the DIP switches, relating to the position of the smart lamp. For example, when the smart lamp is adjacent to another smart lamp system, the DIP switches can include a configuration representing the relative positions of the DIP switches. In an example, the DIP switches can indicate whether the smart lamp is to the left or to the right of a common reference position. The DIP switches can represent the position of the smart lamp by a position of one of the DIP switches. For example, when the smart lamp is on the left of the common reference position, one of the DIP switches can be in an up state, represented as a binary “1” in the corresponding electrical signal. The control logic 400 then proceeds to step 412.
At step 412, in an embodiment, the control logic 400 can assign a smart lamp configuration based on the DIP switch arrangement. For example, the DIP switch arrangement can correspond with a physical position of the smart lamp in relation to other smart lamps. The control logic 400 then proceeds to step 414.
At step 414, in an embodiment, the control logic 400 can identify a status of the at least one LED strip. For example, the control logic 400 can identify which of the LED strips is operational. For example, the control logic 400 can receive inputs from each of the LED strips indicating an ID and a status of the LEDs. In an example, the control logic 400 can identify whether the LED strip is in an inoperable state based on the inputs from the LED strips. Alternatively, the control logic 400 can determine whether the LED strips are in an operable state. For example, the LED strips can transmit the inputs including a binary representation of the state of the LEDs. The control logic 400 can receive the inputs and classify the LED strips based on the states of the LED strips. In an example, the control logic 400 can identify which particular LEDs of the LED strips are inoperable. The control logic 400 then proceeds to step 416.
At step 416, in an embodiment, the control logic 400 can detect an activation failure. For example, the control logic 400 can identify a number of operational LED strips. In an example, when the number of the operational LED strips is below a threshold the characteristics monitoring can generate an alert as the activation failure. The threshold can include a ratio of the operational LED strips to a total number of LED strips. In an example, the threshold can include the ratio to be 50% of the total number of LED strips are operational. The activation failure can correspond to legal compliance with regulations for public safety. For example, the activation failure can correspond to a number of operational LED strips at a railway crossing.
