Problems solved by technology
The bearing temperature of the rail transit vehicle is detected by the infrared sensor installed on the rail transit vehicle. Although the problem that the cable of the sensor is easily damaged due to the use of the axle temperature sensor with its own cable is avoided, the system uses non-contact The infrared shaft temperature detection device detects the bearing temperature, the detection accuracy is low, and the response speed is slow
Moreover, it is necessary to manually guard the monitoring system. When there is an axle temperature alarm, it is necessary to manually notify the train driver and passengers to deal with it in time. It cannot be connected with the train control system to achieve linkage and automatic protection with the train. For rail transit vehicles Protection lacks real-time and effectiveness

The invention provides an on-board monitoring system for wireless transmission of sensors of a bogie of a rail transit vehicle, which comprises sensors, a signal acquisition device, a signal receivingdevice, and an on-board train control device. The sensors and the signal acquisition device are arranged on the bogie of the vehicle; the signal receiving device is arranged on the vehicle body of the vehicle; the on-board train control device is arranged inside a carriage of the vehicle; the bogie is connected to the vehicle body through a connecting piece; the sensors are connected to the signal acquisition device; the signal acquisition device is wirelessly connected to the signal receiving device; the signal receiving device is connected to the on-board train control device. According tothe on-board monitoring system for the wireless transmission of sensors of the bogie of the rail transit vehicle, the sensors detects a bearing temperature, a rotational speed, and acceleration information in the bogie area in real-time; the signal acquisition device transmits the information in real-time to the signal receiving device located on the vehicle body by the method of wireless; and thesignal receiving device transmits the information to the on-board train control device; so that the high-precision real-time detection is achieved, the reliability and the safety of the rail transitvehicle are improved, and the maintenance cost is remarkably reduced.
Description
technical field [0001] The invention belongs to the technical field of vehicle signal detection, and relates to a wireless transmission monitoring system of a bogie sensor of a vehicle-mounted rail transit vehicle. Background technique [0002] A notable feature of rail transit vehicles is "self-guiding", that is, the train does not need the driver to control the direction, but is guided by the track on the line to run. This guiding function is realized by the bogie of the rail transit vehicle. figure 1 A schematic diagram of the position of the bogie provided by the present invention in a rail transit vehicle, Figure 2a For the front view of the bogie provided by the present invention, Figure 2b A top view of the bogie provided by the present invention. Such as figure 1 As shown, the function of the bogie 1 is to bear the weight of the train carriage 2 and at the same time guide the running direction of the train, that is, the bogie 1 moves and turns along the track un...
