工矿内燃机车节能自动换挡控制系统设计

Design of energy-saving automatic shift control system for industrial and mining diesel locomotives

在对工矿内燃机车的动力传动系统和手动换挡过程进行深入解析后,设计了机车的两参数节能自动换挡控制系统。应用转速传感器采集机车的泵轮及涡轮转速信号,再将这两个信号输入到PLC控制器中,经运算处理后,由控制器输出换档控制信号给相应的电磁阀。该节能自动换挡控制系统对工矿内燃机车的自动换挡具有一定工程应用价值。

After deeply analyzing the power transmission system of the industrial and mining diesel locomotive and manual shift process, the paper designed the energy-saving automatic shift control system bearing two parameters. In the system, the rotary speed sensor was applied to acquire the rotary speed signal of the pump and the turbine, and then the two signals were input to PLC and processed by calculation. After that, the PLC output the shift control signal to corresponding electro-magnetic valve. The energy-saving automatic shift control system possessed some engineering application values for automatic shift of the industrial and mining diesel locomotive.
