Design of a locomotive air conditioning test bench
According to the working characteristics of TTK3-5.0DD locomotive air conditioning,a touch screen is used as the control and display interface,and Siemens S7-200CPU224 is used as the controller to control it.RS485 communication mode is selected for hardware communication.A locomotive air conditioning test bench is designed and manufactured,which can complete the performance test of TTK3-5.0DD locomotive air conditioning unit and monitor the working current data of the unit.The num-ber of outsourced repairs for faulty air conditioners has plummeted,and the level of self-repair for air conditioners has significantly improved,so it has high practical value.
