System for monitoring locomotive brake

Abstract

The invention provides a system for monitoring a locomotive brake. The system comprises a locomotive monitoring terminal, a GPRS module, a USB converting CAN module, wireless transmitting and receiving modules, a central control module, a wireless transmitting and receiving module and a pressure sensor, wherein the locomotive monitoring terminal, the GPRS module, the USB converting CAN module andthe wireless transmitting and receiving modules are arranged on a locomotive module; the central control module, the wireless transmitting and receiving module and the pressure sensor are arranged oneach locomotive module; the locomotive monitoring terminal communicates with the GPRS module and the USB converting CAN module and the USB converting CAN module, and the wireless transmitting and receiving module perform data transmission; on the locomotive module, the pressure sensor and the wireless transmitting and receiving modules can both perform data transmission with the central control module through a CAN bus; the data are transmitted between the locomotive modules and between the locomotive modules and the locomotive monitoring modules by the wireless transmitting and receiving modules; and each locomotive module comprises two wireless transmitting and receiving modules which are arranged on the end parts of both sides of the locomotive module. The system for monitoring the locomotive brake has the advantages of enhancing the security of railway transportation, realizing the automatic test on the braking performance of the locomotive in a locomotive test, lowering labor intensity of workers, improving working efficiency, and finally canceling the artificial air testing operation mode.

Description

【Technical field】 [0001] The invention relates to a railway automatic control system, in particular to a train brake monitoring system which automatically detects and analyzes the technical state of each train brake. 【Background technique】 [0002] The train brake is the core component of the vehicle, which is related to the safety of the train. The performance test of the train brake is an important part of the maintenance work of the train inspection station, but the existing train inspection station does not have a special test for the performance of the train brake. The equipment stays in the manual "running wind" check gate state. Simultaneously, when the train is in operation, the vehicle braking machine cannot be monitored throughout the process. [0003] At present, the performance test of the whole train brake is only a simple data record of the train air duct pressure, and it is difficult to detect the technical state of the brake of each car in detail. It is diff...

Problems solved by technology

[0003] At present, the performance test of the brakes of the whole train is only a simple data of the train air pipe pressure record, and it is difficult to detect the technical status of the brakes of each car in detail. This manual operation method is difficult to find early or minor faults of the brakes , the existing technology mainly relies on manual wind testing, which is inefficient and labor-intensive, and there is a lack of brake pressure change data during train operation, which poses certain hidden dangers to the safe operation of the train
