一线网络是一种基于PC或者微控制器的,通过双绞线与一线元件进行数字通信的低成本的总线。机车定置试验台可以模拟再现机车车辆在铁路线上运行的各种工况环境,测试机车车辆的各种性能参数,完成在现有铁路线上行驶所难以达到的试验研究。文章介绍了一线网络在机车试验台温度采集系统中的特殊应用及注意事项。
The first-line network is a PC or microcontroller-based, low-cost bus that digitally communicates with first-line components over twisted pair wires. The locomotive test rig can simulate various working conditions of the locomotive running on the railway line, test various performance parameters of the locomotive and vehicle, and accomplish the test research that is difficult to reach on the existing railway line. The article introduces the special application and precautions of the first-line network in the locomotive test bed temperature acquisition system.
