一种配电站通信故障自动监控系统和方法
摘要：
本发明公开了一种配电站通信故障自动监控系统，包括装载在配电站内的串行通信设备，以及与所述串行通信设备并联的PLC控制器，所述串行通信设备和所述PLC控制器之间通过继电器电连接；所述PLC控制器包括：通信数据采集模块、关键字自学习模块、关键字计数模块、波特率计数模块和重启模块；重启模块在关键字计数模块的关键字计数或波特率计数模块的波特率计数中任意一个大于设定值时，通过所述继电器，重启所述串行通信设备，并记录重启的时间。本发明还公开了一种配电站通信故障自动监控方法，包括数据表建立步骤、关键字自学习步骤、关键字计数步骤、波特率计数步骤和重启步骤。
摘要（英）：

The invention discloses an automatic communication fault monitoring system for a substation. The system comprises a serial communication device loaded in the substation and a PLC controller connectedin parallel with the serial communication device, wherein the serial communication device and the PLC controller are electrically connected by a relay; the PLC controller comprises a communication data acquisition module, a keyword self-learning module, a keyword counting module, a baud rate counting module and a restart module; and the restart module restarts the serial communication device through the relay and records the restart time when any one of the keyword count of the keyword counting module or the baud rate count of the baud rate counting module is greater than the set value. The invention also discloses an automatic communication fault monitoring method for a substation, and the method comprises a data table establishing step, a keyword self-learning step, a keyword counting step, a baud rate counting step and a restarting step.
