摘　　要：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 1-wire net is a low-cost bus based on a PC or microcontroUer communicating digitally over twisted-pair cable with 1-wire components. Fixed test stand is able to simulate various kinds of working conditions of locomotive running on the railway, measure parameters of the loco motive and perform some test and research that can never achieve in on-line test.The special application of 1-wire network in the temperature gathering system of locomotive test bed and some precautions are discussed.
