Online monitoring and early warning system and method for production line

The invention provides a production line on-line monitoring and early warning system and method, and the system comprises sensor modules which are arranged at preset point inspection parts and are used for carrying out the state detection of the point inspection parts; the production line PLC control system is connected with the sensor module and is used for analyzing the state data, collected by the sensor module, of the point inspection parts and giving an early warning prompt when it is judged that the state data exceed a normal range; and the WINCC human-computer interface exchange system is in Ethernet communication with the production line PLC control system and monitors the state data of each point inspection part in real time. The system can realize real-time online monitoring and intelligent early warning of the production line. 本发明提出一种生产线在线监测预警系统及方法，所述系统包括：传感器模块，布置于预设的各个点检部位，用于对各个点检部位进行状态检测；产线PLC控制系统，与所述传感器模块连接，用于对所述传感器模块采集的各个点检部位的状态数据进行分析，在判定超过正常范围时，进行预警提示；WINCC人机界面交换系统，与所述产线PLC控制系统进行以太网通讯，对各个点检部位的
