Urban rail vehicle brake monitoring system and method

Abstract

Disclosed is an urban rail vehicle brake monitoring system and method. The urban rail vehicle brake monitoring system comprises upper-computer monitor systems, brake monitoring devices arranged on carriages and CAN interface cards; the brake monitoring devices are in communication with a double-circuit CAN bus with the CAN interface cards, and the CAN interface cards are in communication with the upper-computer monitor systems through USBs (universal serial bus); the upper-computer monitor systems transmit control signals to the brake monitoring systems via the CAN interface cards, the brake monitoring devices forwards the control signals to a train brake monitoring device, the brake monitoring devices collect status information of the train brake device, and the status information is fed back to the upper-computer monitor systems via the CAN interface cards.

Description

technical field [0001] The invention belongs to the technical field of railway electronics, and in particular relates to a brake monitoring system for urban rail vehicles. Background technique [0002] In recent years, the rapid development of transportation forms based on rail vehicles such as high-speed railways, bullet trains, and light rails at home and abroad has put forward higher requirements for the reliability and safety of the vehicle braking system, and then the debugging and operation monitoring of the braking system Technology also places higher demands. [0003] The brake monitoring system is connected to the external CAN interface of the brake control device, receives the status information, control information and fault information sent by the vehicle brake control device, and sends these data information to the host computer (such as a laptop computer) through Ethernet or USB ), in the form of indicator lights, data lists and dynamic curves, to monitor the ...

AI Technical Summary

Problems solved by technology

The disadvantage is that only a single brake control device can be monitored, and the information of one unit cannot be monitored

[0006] 2. The other is to connect the braking control device of a unit together through the CAN bus, and then transfer all the data of the unit into RS232 form and interact with the host computer through a device, so as to achieve the purpose of common monitoring, so that the host computer It can truly reflect the operation of a unit, but with the development of technology, the composition of the braking system unit is constantly changing, and some of them are composed of three or four vehicles as a unit. Quickly exchange all data to the host computer, which affects the monitoring of braking performance

[0007] 3. The current brake monitoring system only plays the role of monitoring, and has not yet participated in the control

[0008] 4. The recording of all data on site can only be carried out after connecting with the notebook, and the recording of big data in the operation of the vehicle without the notebook has not been well resolved

[0010] 1. Hardware: It is the board inside the brake control device that completes the information interaction between the brake control device and the host computer. This board is generally the main control board to take care of this function, which may affect the main control board. work, and cannot complete information interaction efficiently, and cannot complete SD card storage

[0011] 2. In terms of software: the existing host computer software only presents the information processing in the form of lists, indicator lights, and text boxes, and cannot dynamically express the coordination between various signals, such as braking commands, braking The cooperation between the cylinder pressure and the electric brake pressure; the storage of on-site data, and the offline data playback processing are not well realized
