The speed sensor C is installed on the tire drive axle housing on the right side of the vehicle, the temperature sensor B is installed on the surface of the engine, the liquid level sensor A is installed in the vehicle water tank, the liquid level sensor B is installed in the vehicle fuel tank, the hydraulic sensor is installed in the vehicle main oil channel, the temperature sensor A is installed on the end surface of the vehicle exhaust pipe, the carbon monoxide sensor is installed on the left side frame of the vehicle, the methane concentration sensor is installed at the end of the vehicle exhaust pipe, the temperature sensor C is installed on the water jacket of the engine cylinder head, the programmable logic controller is installed in the cab, the switch is installed in the vehicle cab, the gateway is installed on the top of the vehicle cab, the camera is installed on the top of the vehicle cab, and the MCGS touch screen is installed in the cab.

[0005] The programmable logic controller in the vehicle-mounted subsystem is used to receive signals from each sensor and transmit them to the switch through a network cable. The switch completes the network port expansion. On the one hand, it sends the signal to the MCGS touch screen to display the measured relevant physical quantities to the driver. On the other hand, it sends the signal to the gateway. The gateway transmits the signal wirelessly to the lane base station near the vehicle.

[0006] The MCGS touch screen in the vehicle-mounted subsystem is used to display the measured relevant physical quantities to the driver and provide the driver with vehicle status and environmental information.

[0007] In the vehicle-mounted subsystem, a camera is installed on the top of the cab of the trackless rubber-tyred vehicle to capture the environment in front of the vehicle. The camera is connected to the gateway, and the captured video signal can be transmitted wirelessly to a lane base station adjacent to the vehicle.

[0013] The programmable logic controller (PLC) and camera transmit data to the gateway via an Ethernet cable. The gateway transmits the data wirelessly to the tunnel base station. The administrators of the tunnel monitoring end and the ground monitoring end open the local service port to determine whether the local service port has been connected. After the connection is successful, the tunnel monitoring end and the ground monitoring end read the data and determine whether the data exceeds the threshold. If the threshold is exceeded, an alarm is issued and the alarm information is recorded; if the threshold is not exceeded, the tunnel monitoring end and the ground monitoring host computer display and record the corresponding analog information, digital information and video information. If the monitoring process needs to be stopped, the monitoring program is stopped; if the monitoring needs to continue, the monitoring program is continued according to the above process.

[0014] The parts not involved in the device are the same as the existing technology or can be implemented by using the existing technology. The utility model is conducive to timely discovery of faults of mining trackless rubber-tyred vehicles and hidden dangers in their driving environment. When there is an abnormal situation, the system will automatically alarm and prompt the management personnel to conduct an investigation, providing necessary guarantees for timely elimination of related faults and hidden dangers.
