Abstract
Level sensor remote monitoring system based on industrial process control for the design blueprint; experimental device PLC as the core. By means of which students can sensing, detection, control experimental system, to improve students' ability to analyze and solve problems. By design level sensor monitoring system remote monitoring system experiments, the students in the experiment, it is possible to understand the system's real-time information and control methods to master the basic process of industrial control, for students of engineering knowledge and practical ability is important.
This topic through remote monitoring system design level sensor test monitoring system, PLC control system composed understand; learn to use HMI development software development and design Kingview monitoring system;; training S7-200PLC module electrical wiring and other devices to learn use PC software to monitor the health of PLC; learn to put into operation with a PC system monitoring software; learn how to use PC monitoring software for PID control, learn to run the operating method based on configuration content design and development of monitoring and control of the king and the PLC include: landing interface, trend curve interface, report interface.
The experimental monitoring system developed by the actual debugging, results showed that the experimental monitoring system and PLC communication is successful, enter the normal operation mode under PLC View operation, it is possible to manage the experiment, the system can be put into operation experiments, experiments can be performed PID control system, to achieve the development requirements of the corresponding function.
Keywords: liquid level sensor remote monitoring systems; experimental monitoring system; kingview; PID; PLC
