[0013] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention. Example

[0014] like Figures 1 to 6 As shown, an automatic lane indicator maintenance system includes: The detection module 1 is used to detect faults in the control card / power supply 4. When a fault is detected in the control card / power supply 4, a fault signal is generated. Control module 2 is used to receive the fault signal from detection module 1, identify the control card 401 or power supply 403 as a faulty control card or faulty power supply, and generate a control signal based on the fault signal. Maintenance module 3 performs maintenance on fault control card 401 or power supply 403 according to control signals, automatically disconnects the power supply of control card 401 or power supply 403, and switches the power supply to backup control card 402 or backup power supply 404 for automatic maintenance.

[0015] The detection module 1 continues to continuously detect the switched backup control card 402 or backup power supply 404, and at the same time uploads the log text of the production and maintenance process to the host computer.

[0016] In practical applications, the entire system operates automatically. Detection module 1 continuously monitors the data from the control card / power supply 4. It continuously monitors the output signal from the control card to the light board through the control card detection port 101; it continuously monitors the 5V output current and voltage of the control card through the power supply detection port 102; and it detects the temperature and humidity of the control card through the temperature and humidity sensor 405. When any data is abnormal, detection module 1 automatically generates a log text, records the fault information, and simultaneously sends a corresponding fault signal to control module 2. Detection module 1 also continuously monitors the data from the control card 401 and power supply 403, continuously monitoring the output current and voltage of the power supply through electrical signals; and it detects the temperature and humidity of the power supply through the temperature and humidity sensor. When any data is abnormal, detection module 1 automatically generates a log text, records the fault information, and simultaneously sends a corresponding fault signal to control module 2.

[0017] After receiving a fault signal, control module 2 identifies the faulty control card or power supply by recognizing the fault information and then sends a command to maintenance module 3. Simultaneously, the command sent by control module 2 is automatically recorded in the log file.

[0018] Maintenance module 3 executes actions according to instructions. If it receives a current or voltage fault instruction for control card 401, it automatically disconnects the input power of the faulty control card 401, switches the power supply to the backup control card 402, and activates the backup control card 402. If it receives a power fault instruction for power supply 403, it automatically disconnects the input power of the faulty power supply 403, switches the power supply to the backup power supply 404, and activates the backup power supply 404.

[0019] The detection module 1 continues to continuously detect the switched backup control card 402 and backup power supply 404. At the same time, the log texts of the detection module 1, control module 2, and maintenance module 3 can be viewed remotely to trace fault information and executed instructions.

[0020] In this embodiment, the detection module 1, control module 2, and maintenance module 3 work together to automatically detect, maintain, and provide early warnings for common control card and power supply failures in lane indicators. This significantly reduces the failure rate of lane indicators and lowers the difficulty and cost of long-term operation and maintenance. The early warning function provides customers with the option to choose maintenance times, such as during road maintenance periods or when the weather is good, saving administrative road closure costs and avoiding high-risk operations in inclement weather. The system can view fault details, and for some temperature and humidity-related faults, it may discover problems with the enclosure, such as water leakage, allowing for timely handling and preventing the problem from escalating. Differentiating between control card and power supply faults facilitates accurate procurement of spare parts and reduces additional costs. The automatic switching mechanism of the maintenance module ensures that idle equipment is not powered, avoiding dual power supply, reducing energy consumption, and effectively extending the service life of the control card, power supply, and system. In the above embodiments, the control card / power supply 4 includes: The housing 406 has a lamp panel on its front and an installation plate 407 inside.

[0021] Mounting plate 407 is provided with mounting holes for control card 401, spare control card 402, power supply 403, spare power supply 404, and automatic maintenance motherboard 5. Each mounting hole is used to install a corresponding card and power supply.

[0022] Control card 401, the working control card 401 is vertically arranged on the upper left side of the mounting plate 407, the signal output terminal of the control card 401 is connected to the display panel, and the input power is connected to the 5V output interface 301 of the automatic maintenance motherboard 5; The backup control card 402 is vertically arranged on the lower left side of the mounting plate 407. The signal output terminal of the backup control card 402 is connected to the display panel, and the 5V input power supply is connected to the 5V output interface 301 of the automatic maintenance motherboard 5. Power supply 403, the working power supply 403 is vertically arranged on the upper right side of the mounting plate 407, the 5V output terminal of power supply 403 is connected to the 5V input interface 201 of the automatic maintenance motherboard 5, and the 220V input terminal of power supply 403 is connected to the 220V output interface 302 of the automatic maintenance motherboard 5. Backup power supply 404 is vertically arranged on the upper right side of the mounting plate 407. The 5V output terminal of the backup power supply 404 is connected to the 5V input interface 201 of the automatic maintenance main board 5, and the 220V input terminal of the backup power supply 404 is connected to the 220V output interface 302 of the automatic maintenance main board 5. Automatic maintenance motherboard 5, which is vertically arranged in the center of the mounting plate 407; In the above embodiments, the automatic maintenance motherboard 5 includes: The barrier-type terminal block 501 serves as a connection port on the maintenance module. It secures the power cord to other modules using screws and detects electrical signals via the power cord. A normal power supply is detected, indicating normal operation; no electrical signal is detected, or multiple electrical signals are detected, indicating an anomaly. The control card detection interfaces 101 and 102, power detection interface 102, 5V output interface 301, and 220V output interface 302 are all equipped with barrier-type terminal blocks 301. The control module 2 consists of a control chip 503 and multiple relays 502. The control chip receives detection signals and feeds them back to the relays to switch the power supply to the control card and the power source.

[0023] In practical applications, when the control chip 503 detects an abnormal signal from the control card 401 through the control card detection interface 101, the control chip 503 feeds back to the relay 502, which disconnects the power supply to the control card 401 and connects to the power supply of the backup control card 402; when the control chip 503 detects an abnormal power signal from the 403 through the power detection interface 102, the control chip 503 feeds back to the relay 502, which disconnects the 220V input power supply to the power supply 403 and connects to the power supply of the backup power supply 404. This embodiment uses a power relay, which has a long lifespan with unlimited mechanical and electrical lifespan; high withstand voltage, with a maximum switching voltage of 250V@AC / 110V@DC and a maximum switching current of 5A; and multiplexing in the maintenance module to fully meet the requirements of the lane indicator, ensuring long-term stable operation and achieving zero failures and no damage throughout the entire service life.

[0024] The above embodiments also include: Temperature and humidity sensor 504 is integrated into the control module through chip-level packaging. When the control chip detects that the temperature and humidity of the sensor exceeds the preset temperature range, it immediately sends an early warning message to the host computer and records it in a log file. When the temperature exceeds the preset critical line, the control chip sends a control card and power-off command.

[0025] The control card detection interface 101 is connected to the output signals of the control card 401 and the backup control card 402 respectively through the fence-type terminal block 501, and the other end is connected to the control chip detection pin of the control chip through the internal circuit of the circuit board.

[0026] In practical applications, when the output signal of the control card 401 is normal and the control chip is recognized normally, the 5V output interface 301 of the automatic maintenance motherboard 5 is normally connected to the control card 401; when the output signal of the control card 401 is abnormal and the control chip is recognized abnormally, the 5V output interface 301 of the automatic maintenance motherboard 5 is disconnected from the control card 401 and the power supply of the backup control card 402 is switched. Power detection interface 102, the power detection interface 102 is connected via a fence-type terminal block. It is connected to the output signals of power supply 403 and backup power supply 404 respectively, and the other end is connected to the power detection pin of the control chip through the internal circuit of the circuit board.

[0027] In practical applications, when the power supply 403 outputs a normal signal and the control chip recognizes it normally, the 220V output interface 302 of the automatic maintenance motherboard 5 is normally connected to the power supply 403; when the power supply 403 outputs an abnormal signal and the control chip recognizes it abnormally, the 220V output interface 302 of the automatic maintenance motherboard 5 is disconnected from the 220V power supply of the power supply 403, and the power supply connected to the backup power supply 404 is switched. This embodiment uses a detection module, a control module, and a maintenance module as the core to form an automatic maintenance system. Through coordinated operation, it realizes automatic maintenance of lane indicators, reduces the frequency of manual maintenance of control cards and power supplies, and is suitable for outdoor long-term operation scenarios. Example

[0028] like Figure 7 As shown, an automatic maintenance method for lane indicators includes the following steps: The detection module 1 performs fault detection on the control card / power supply 4. When a fault is detected in the control card / power supply 4, a fault signal is generated. The control module 2 receives the fault signal from the detection module 1, identifies the control card / power supply 4 as a faulty control card / power supply 4, and generates a control signal based on the fault signal. Maintenance module 3 performs automatic maintenance on the fault control card / power supply 4 based on control signals.

[0029] The detection module 1 continues to perform fault detection on the backup control card / power supply. When a fault is detected in the backup control card / power supply, an alarm message is sent. In practical applications, the detection module 1 continuously detects the data of the control card / power supply 4: the feedback signal detects the output signal of the control card to the lamp board; the electrical signal continuously monitors the output current and voltage of the control card and power supply; the temperature and humidity sensor detects the temperature and humidity of the control card and power supply; when one of the data is abnormal, the detection module 1 automatically generates a log text, records the fault information, and sends the corresponding fault signal to the control module 2. After receiving a fault signal, control module 2 identifies the type of fault by recognizing the fault information, such as control card failure, power supply failure, or temperature and humidity failure. Then, it sends the corresponding control command to maintenance module 3. At the same time, the commands sent by control module 2 are automatically recorded in the log text.

[0030] Maintenance module 3 executes actions according to instructions. If it receives a warning control message, such as a temperature and humidity fault, it sends a warning message. If it receives a current and voltage fault instruction for the highest-level control card, it automatically disconnects the input power of the faulty control card 401, switches the power supply to the backup control card 402, and activates the backup control card 402. If it receives a power fault instruction for the power supply 403, it automatically disconnects the input power of the faulty power supply 403, switches the power supply to the backup power supply 404, and activates the backup power supply 404.

[0031] The detection module 1 continues to continuously detect the switched backup control card and backup power supply. At the same time, the log texts of the detection module 1, control module 2, and maintenance module 3 can be viewed remotely to trace fault information and executed instructions.

[0032] In this embodiment, the detection module 1, control module 2, and maintenance module 3 work together to automatically detect, maintain, and provide early warnings for common control card and power supply failures in lane indicators. This significantly reduces the failure rate of lane indicators and lowers the difficulty and cost of long-term operation and maintenance. The early warning function provides customers with the option to choose maintenance times, such as during road maintenance periods or when the weather is good, saving administrative road closure costs and avoiding high-risk operations in inclement weather. The system can view fault details, and for some temperature and humidity-related faults, it may discover problems with the enclosure, such as water leakage, allowing for timely handling and preventing the problem from escalating. Differentiating between control card and power supply faults facilitates accurate procurement of spare parts and reduces additional costs. The automatic switching mechanism of the maintenance module ensures that idle equipment is not powered, avoiding dual power supply, reducing energy consumption, and effectively extending the service life of the control card, power supply, and system.
