Description

A traffic light sensor system for underground inclined ramps Technical Field

[0001] This utility model relates to the field of underground mining operation technology and equipment, specifically an underground inclined ramp traffic light sensing system. Background Technology

[0002] In underground mining operations, ramps serve as the primary transportation routes for vehicles, and their safe operation is crucial. Due to the complex and ever-changing underground environment, vehicles may face numerous risks during operation, among which vehicle stalling is extremely dangerous. Once a vehicle stalls, it can not only cause vehicle damage but also lead to serious accidents resulting in casualties. Therefore, effectively monitoring and controlling vehicle speeds on underground ramps has become an important issue in mine safety management.

[0003] Traditional methods for controlling the speed of underground ramps often rely on manual monitoring or simple mechanical speed limiting devices, which have many shortcomings. Manual monitoring depends on the experience and responsibility of the monitoring personnel, is easily affected by human factors, and is difficult to achieve all-weather, all-round monitoring. Mechanical speed limiting devices may become ineffective or even fail due to wear, malfunction, or other reasons. Summary of the Invention

[0008] The vehicle-mounted terminal is configured to receive signals sent by the card reader and calculate the physical distance between the vehicle and the card reader through a bilateral ranging algorithm. The vehicle-mounted terminal transmits signals to the card reader through a wireless communication module.

[0009] A speed calculation module, located in the vehicle terminal, is used to compare the distance difference between two distance measurement results to obtain the real-time physical speed of the vehicle.

[0011] The card reader is also configured to trigger the vehicle-mounted smart terminal to broadcast an overspeed reminder to the driver via wireless signal. In the emergency state, the vehicle-mounted terminal can receive a reply from the driver confirming the abnormal speed loss. The system will release the vehicle-stopping device to stop the vehicle in an emergency based on the driver's reply or the change in vehicle speed.

[0015] The speed monitoring unit calculates the vehicle's real-time speed by comparing continuously calculated physical distances and determines whether the speed change exceeds the stall anomaly setting value.

[0016] The reminder broadcast unit notifies the driver of an overspeed warning via the in-vehicle intelligent terminal when the speed change exceeds the stall anomaly setting value. The reminder broadcast unit is connected to the audio output device of the in-vehicle intelligent terminal.

[0017] Optional, also includes:

[0018] The driver confirmation module is configured to receive confirmation of the stalling abnormal state from the driver via voice response after the vehicle terminal broadcasts an overspeed warning.

[0022] When the emergency protection trigger module is activated, the traffic light control module will control the traffic lights to display a no-passing state until the system confirms that the vehicle has returned to a safe speed or the emergency has been resolved.

[0023] Optionally, the vehicle-mounted terminal further includes:

[0024] The self-test module is configured to periodically perform self-tests on each functional unit of the vehicle terminal to ensure that each unit is working properly.

[0061] This system uses wireless communication technology to achieve real-time communication between the card reader 1 and the vehicle terminal 2. The card reader 1 is deployed in the underground tunnel to send wireless signals to the vehicle terminal 2. After receiving the signal, the vehicle terminal 2 calculates the physical distance between the vehicle and the card reader 1 using a bilateral ranging algorithm. Then, by comparing the distance difference between the two ranging results, the real-time speed of the vehicle is obtained.

If the vehicle is speeding, the reminder broadcast unit 8 broadcasts an overspeed reminder to notify the driver through the vehicle intelligent terminal, the driver confirmation module 9 receives the driver's voice reply and confirms the stall anomaly state, if the vehicle stalls and the driver does not reply or confirms the stall anomaly, and the vehicle is not in an effective braking state, the automatic execution module 10 performs the stall emergency disconnection and vehicle blocking release work. At the same time, the traffic light control module 12 controls the traffic lights to display the prohibition state until the system confirms that the vehicle has returned to a safe speed or the emergency is completed. The self-test module 13 periodically performs self-tests on each functional unit of the vehicle terminal 2, and the fault alarm unit 14 issues an alarm message when a fault is detected.

[0063] The self-test module 13 and the fault alarm unit 14 of this application are integrated in the vehicle terminal 2. The self-test and fault alarm functions are realized through software algorithms and hardware circuits. The system calculates the physical distance between the vehicle and the card reader 1 in real time through wireless communication between the vehicle terminal 2 and the card reader 1, and then obtains the real-time speed of the vehicle. When the vehicle speed exceeds the preset limit, the system broadcasts an overspeed warning to the driver through the vehicle intelligent terminal, effectively preventing the safety hazards caused by speeding.

[0064] When the vehicle speed change exceeds the stall anomaly setting value, the system triggers emergency protection, such as automatically executing the stall emergency disconnection and release of the vehicle blocking device 11 to prevent the vehicle from going out of control and causing an accident. The emergency protection trigger module 4 is electrically connected to the vehicle terminal 2 to ensure the timeliness and effectiveness of the emergency measures.
