Abstract:

The remote control of the traditional servo ground energy is realized by the simulation. It has a low degree of automation and poor anti-interference ability.In order to solve the above problems,it proposes a remote control solution based on PLC for ground energy.It uses a distributed PLC control technology based on Profibus fieldbus,a closed-loop control technology based on high-voltage output feedback,an OPC Server and PLC telematics technology. This realizes the remote automatic control function. It also uses a virtual instrument technology based on the man-machine interface to replace the analog interface,a digital network sensor based on the Modbus protocol instead of an analog sensor. This realizes the digital servo ground energy system and improves the anti-interference ability of servo ground energy control.
