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.
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 operation, LED lamps provide greater visibility to motorists and pedestrians. Additionally, LED lamps do not utilize a filament for operation effectively providing greater lifecycles versus traditional incandescent 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 be 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.
Accordingly, the present disclosure provides the technological benefit of monitoring statuses of LEDs using a logic controller to generate a payload compliant with a plurality of communication protocols. 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 can be implemented anywhere LED lamps can be utilized, including, vehicle headlights, signaling devices, and lighting components, among others.

In another example, the label can include the IDs corresponding to each of the lamps. For example, when a mast includes four lamps (two front, two rear) and one of the lamps is inoperable (transmitting a “0” state). If the same mast is transmitting two “0” states for the front pair of flashers, the PLC receiver can generate an alarm or an alert indicating an activation failure is in effect. The alarm or alert can correspond to the level of response needed from a technician. The alarm and alert conditions can include the following information.
The master crossing relay can include a structure blocking an accessibility to a railway crossing. In an example, the status report from the lamps can correspond to a status of the operability of the lamps, in no way is the example above meant to limit the breadth of the statuses used for a particular application. Rather, the example above is meant to be explanatory in nature. In another example, the alert can correspond to the activation failure, indicating more than 50% of the lamps are inoperable. In an example, the alarm can correspond to a general alarm indicating greater than 50% but less than 100% of the lamps are operational.

All the DIP switches can be configured as a binary 7-digit ID to ensure that the PLC receiver understands when to receive a message from each of the smart lamps. For example, in the situation when two lamps have been assigned to a first label path of a front pair, the web GUI can generate a front left label and a front right label. In an example, the first front-facing lamp 302 can have an ID of “1111110,” where the first digit denoting left side, remaining digits denoting delay. In another example, the second front-facing lamp 304 can have an ID of “0111110,” where the first digit denoting right, remaining digits denoting delay. When the 7-digit ID can be configured within the web GUI, the PLC receiver can understand two lamps can be transmitting statuses at certain time slots. In an example, the lamps can transmit a message every 1-second cycle.

In another example, the lamps can perform a variety of actions for the window of activation. For example, each of the lamps can perform four actions during a corresponding 1-second window of activation. The protocol actions can include wakeup, delay, transmission, and silence. The wakeup action can include the system receives power, performs self-diagnostic checks, and prepares the system 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 system transmits the 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.
In another example, the PLC receiver can have a similar set of actions for each of the messages received from the lamps. In an example, the PLC receiver can always have power and can trigger receiving messages in response to an input from the main crossing relay. In an example, the PLC receiver can perform a variety of actions when triggered. For example, the actions can include a crossing relay down action, a message receipt action, a message transmission action, and a crossing relay up action. The crossing relay down action can trigger the PLC receiver to begin receiving messages from the lamps. The message receipt action can indication when the PLC receiver is to receive a message from the lamps. The message transmission action can trigger the PLC receiver to transmit lamp IDs and statuses. The crossing relay up can trigger the PLC receiver to stop performing any actions and to standby for further instructions.

In an embodiment, the PLC interface system 606 can monitor when the LEDs are in an inoperable state and communicate the statuses of the LEDs and DIP switch positions to the PLC receiver to identify whether action is needed for the LEDs (i.e., to repair or replace any LEDs or the smart lamp).
The PLC status module 522, in an embodiment, can identify a status of a PLC receiver. For example, the PLC receiver can be disconnected from the smart lamp system 600, resulting in no power-line communications transmitted to the smart lamp system 600. In this way, the PLC status module 522 can identify the PLC receiver is inoperable. In another example, the PLC status module 522 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 522 to enable communications between the two components. The PLC status module 522 can receive the notification from the PLC receiver and begin the data communication process.
The characteristics monitoring module 524, in an embodiment, can monitor various characteristics of the smart lamp system 600. For example, the characteristics monitoring module 524 can monitor voltage, current, and DIP switch arrangement of the smart lamp system 600. In an example, the characteristics monitoring module 524 can identify a value of the voltage based on power-line transmission between the PLC interface system 606 and the PLC receiver. In an example, the characteristics monitoring module 524 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 600 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 524 can identify a value of the current based on power-line transmission between the PLC interface system 606 and the PLC receiver. The characteristics monitoring module 524 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 524 can detect an activation failure. For example, the characteristics monitoring module 524 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 526, in an embodiment, can transmit data between the PLC interface system 606 and the PLC receiver. For example, the communication module 526 can generate a communication payload organizing the DIP switch positions and the statuses of the LED strips in a binary format. The communication module 526 can transmit the data in a time duration corresponding to a particular application. For example, the communication module 526 can transmit the data in a 1-second time window. In an example, the communication module 526 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 700 can include a plurality of DIP switches for representing an identifier of at least one LED strip. The smart lamp control logic 700 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 700 can further include a memory for storing the DIP switch positions, the statuses, and configuration enabling information. Additionally, the smart lamp control logic 700 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 700 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 700 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 700 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 700 can also be distributed amongst a plurality of networked computer processors. The smart lamp control logic 700 of the present embodiment begins at step 702.
At step 702, in an embodiment, the control logic 700 can represent an identifier of at least one LED strip. For example, the control logic 700 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 700 can identify the LED strip based on an LED ID corresponding to each of the LED strips. In an example, the control logic 700 can include LED information corresponding to the LEDs present in the smart lamp. The control logic 700 can compare input signals from the LEDs to the LED information to identify the LED strips. The control logic 700 then proceeds to step 704.
At step 704, in an embodiment, the control logic 700 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 700 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 700 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 700 then proceeds to step 706.
At step 706, in an embodiment, the control logic 700 can monitor the voltage, current, and DIP switch arrangement. For example, the control logic 700 can monitor voltage, current, and DIP switch arrangement of the smart lamp. In an example, the control logic 700 can identify a value of the voltage based on power-line transmission between the P control logic 700 and a PLC receiver. The control logic 700 can identify a value of the current based on power-line transmission between the control logic 700 and the PLC receiver. The control logic 700 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 700 then proceeds to step 708.
At step 708, in an embodiment, the control logic 700 can transmit lamp information to the power-line transceiver. For example, the lamp information can include the DIP switch positions and statuses of the LED strips. The control logic 700 then proceeds to step 710.
At step 710, in an embodiment, the control logic 700 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 700 then proceeds to step 712.
At step 712, in an embodiment, the control logic 700 can identify a status of the at least one LED strip. For example, the control logic 700 can identify which of the LED strips is operational. For example, the control logic 700 can receive inputs from each of the LED strips indicating an ID and a status of the LEDs. In an example, the control logic 700 can identify whether the LED strip is in an inoperable state based on the inputs from the LED strips. Alternatively, the control logic 700 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 700 can receive the inputs and classify the LED strips based on the states of the LED strips. In an example, the control logic 700 can identify which particular LEDs of the LED strips are inoperable. The control logic 700 then proceeds to step 714.
At step 712, in an embodiment, the control logic 700 can detect an activation failure. For example, the control logic 700 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.

1. Providing a lighting system with the ability to monitor various states of LEDs using a combination of power-line communications and electrical hardware.
2. Enabling efficient communications between the lighting system and a network using a communication protocol to monitor the states of LEDs.
3. Minimizing light failures by generating an alert in response to a state of the LEDs indicating LED inoperability.
