The invention discloses a PLC-based automatic test device for train air-conditioning control panels. After the automatic test device is installed normally, the upper machine will automatically initialize the monitoring device and the detection device, and the debugging personnel will then adjust the gear position according to the display data returned by the upper computer initialization. The information and communication address information are modified and defined, and the host computer controls and inspects item by item according to the test strategy, and obtains control information and inspection information to complete the inspection. The present invention only needs the debugging personnel to connect the serial port and the interface, install the monitoring device and the detection device, modify and define the gear position information and the communication address information, and can automatically complete the automatic test of the train air-conditioning control panel, which saves a lot of labor with less manual operation The advantages of time and automatic testing are fast and efficient.
Description
technical field [0001] The invention relates to the technical field of control panel testing, in particular to a PLC-based automatic testing device for train air-conditioning control panels. Background technique [0002] As the core equipment of train air-conditioning control, the air-conditioning control panel participates in the functional operation of air-conditioning fans, condensers, compressors and other equipment, and plays a decisive role in the operation of the air-conditioning system. The air conditioner control panel has a large number of components and corresponding wiring. The workload of checking and debugging the control panel is large, which takes up a lot of time in the entire production cycle and brings many uncertain factors to the progress of the project. The purpose of developing an automatic test device is to reduce manpower and time, and complete the work of checking lines and debugging. PLC has been widely used in the industry, and the development of...
