摘　　要：传统伺服地面能源系统的远程控制主要通过模拟量来实现,其自动化程度低、抗干扰能力差;为了解决以上问题,提出了一种基于PLC的地面能源远程控制方案,其分别采用了基于Profibus现场总线的分布式PLC控制技术、基于高压输出反馈的闭环控制技术、OPC Server与PLC远程通讯技术,实现了伺服地面能源系统的远程自动化控制功能,用基于虚拟仪器技术的人机交互界面取代模拟器件,用基于MODBUS协议的数字式网络传感器取代模拟传感器,实现了伺服地面能源系统数字化,提高了伺服地面能源系统的抗干扰能力。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 instru ment 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.
