Research on the design of data acquisition software for ZD6-E/J switch machine

The switch machine is an important piece of equipment on the railway site. Mastering the working parameters of the switch machine is not only of great significance for the maintenance and upkeep of the equipment, but also provides data support for the prediction and analysis of switch machine faults in the later stage. This paper designs a software that can not only control the lower computer to set faults but also collect the action current, indication voltage and relay status information of ZD6-E/J switch machine. This software includes six modules: working principle, fault setting, real-time status, action current, indication voltage and system setting. The working principle is used to explain the working principle of the turnout, the fault setting is used to set the switch machine fault, the relay status is used to display the status of the signal relay in the combination, the action current is used to display the current value during the turnout action process, the indication voltage is used to display the current working voltage value, the system setting is used to set the communication parameters. The software and the lower computer adopt the Modbus TCP communication protocol. The software can help researchers obtain experimental data for fault prediction research and also provide research cases for railway signal workers to analyze faults.
