Abstract: An electro-optical monitoring system based on PLC and wireless sensor networks was built to overcome the deficiencies of traditional monitoring system. We analyzed the components of the optical monitoring system and its working principle，discussed the implementation of optical wireless sensor-networks based on remote sensing technology and investigated the feasibility of the software and hardware implementation of the ABB PLC as well as the development risk of Fame View software．This paper takes AC500 PLC produced by the ABB Company as the main control device, polling the wireless sensor nodes by the order address through the Modbus protocol to collect the data and dealing with the data accordingly, and the final result is passed to the host computer. The received data is used to generate monitor screen by FameView configuration software for real-time detection and monitoring of the operation site．The Monitoring is flexible and effective, and data collection is more efficient, and the system can be upgraded easily. The new optical monitoring system can find its application in production, the battlefield environment, and many other military and civilian fields.-
