基于VS.NET及串口通讯的线控制动操控系统开发与验证

线控制动系统中信号传输处理的速度及稳定性会对整个制动操控效率产生决定性的影响，是影响制动距离及其恒定性的主要因素之一。选择不同的开发平台和通讯类型，其效果也不一样。本研究基于VS.NET平台及串口通讯方式，设计开发线控制动的操控系统，围绕制动操控效率和可靠性两个目标元素，从生效速度、操控效率的稳定性两个方面对线控制动操控系统进行性能验证，包括制动需求分析、开发背景介绍、系统设计以及基于紧急持续制动、点动缓刹、常规持续限速三种典型工况下的性能验证。

DEVELOPMENT AND VERIFICATION OF BRAKE-BY-WIRE CONTROL SYSTEM BASED ON VS.NET AND SERIAL COMMUNICATION

The speed and stability of signal transmission and processing in the brake-by-wire control system has a decisive impact on the whole braking control efficiency, also is one of the main factors affecting the braking distance and constancy. Different development platforms and communication types have different effects. Based on VS.NET platform and serial port communication mode, the brake-by-wire control system was designed and developed, focusing on the two objective elements of braking control efficiency and reliability, the performance verification of the line control brake control system was carried out, including braking demand analysis, development background introduction, system design, and performance verification under three typical working conditions as emergency continuous braking, inching braking and conventional continuous speed limit.
