- Abstract
During the operation process, the performance status of railway freight car braking system is mainly checked by train inspection. At present, there is no mature online monitoring solution in the world. In order to realize real-time monitoring of vehicle braking system, it is necessary to have on-board devices for data acquisition and transmission functions of the braking system. The acquisition and transmission of data require power consumption. There is neither communication cable nor power supply cable for freight cars. Therefore, in order to achieve online braking monitoring, it is necessary to solve the wireless communication problem of on-board vehicle under the condition of low power consumption.This paper introduces a solution for data transmission of brake monitoring of on-board low power consumption. In this paper, the technology of node clustering and networking, communication path optimization and self-healing and other network stabilizing technologies, as well as power management and energy saving technologies such as automatic sleep and intelligent wake-up are used to make it suitable for the existing wireless communication cables of railway freight cars. The line has special application environments such as tunnels and bridges, so as to help the railway freight car braking system achieve online monitoring.
