摘要
速度信号是电力机车运行中的重要数据,电力机车闭环调速系统要利用速度信号来构成闭环控制系统,司机控制室的列车运行监控记录装置要以速度信号为工作基准。速度记录仪以MCS51单片机为控制和处理核心,加以相应的外围电路,将机车在行驶过程中的速度信息记录下来,供工作人员分析查询以及维护速度传感器,从而降低故障率,保障行车安全。
The speed signal is an important datum when electric locomotive going, it is used by the closed loop timing system of electric locomotive to compose the closed loop control system, and it is regarded as the working datum by running monitor recorder in locomotive cab. The speed information of locomotive is registered by a speed recorder with MCSSI, in addition with the corresponding peripheral circuits, it is used for staff members to analyze and maintenance of the speed sensor in order to ensure the traffic safety.
