地铁自动售检票设备测试用RS232通信数据监视装置设计

Design of RS232 Communication Data Monitoring Device for Metro Automatic Fare Collection Equipment Testing

在地铁自动售检票设备测试过程中,需要通过监视设备间通信数据状态,判断设备间通信是否正常,快速定位故障设备。为此,研制RS232通信数据监视装置。RS232通信数据监视装置由接口设备、工控机和RS232线缆等组成。装置在查找地铁自动售检票设备故障过程中进行应用。经应用证明,装置能实时接收和显示设备间RS232通信数据,实现对RS232通信数据的监视功能。

During subway automatic fare collection equipment testing, it is necessary to judge whether the communication between equipment is normal by monitoring the communication data status between equipmen, and quickly locate the faulty equipment. Therefore, the RS232 communication data monitoring device composed of interface equipment,industrial personal computers and RS232 cables is developed. The device is applied in the process of troubleshooting metro AFC equipment. The application proves that the device can receive and display the RS232 communication data between devices in real time, and realize the monitoring function to RS232 communication data.
