摘要(Abstract):

介绍了涡旋压缩机组供气系统的组成及其工作原理。采用上位PC机和变频器成功实现了对该供气系统的控制,通过调节各压缩机的运行状态实现机组流量在一定范围内动态变化以更好地满足用户需求。利用VB本身的通信控件MSComm开发的通信软件实现上位PC机与变频器的串口通信,利用PC机可视化控制系统监控软件可实现供气系统的实时监控、控制信号的产生与传输,实现了智能化控制和管理。该控制系统可以提高系统的性能,是一种简单、实用的供气控制系统。
The makeup and work principium of the group of scroll compressor' gas supply system were introduced and the control system of gas supply was realized with super PC and frequency converter.Scroll compressor dynamic change of flux was realized by changing the running state of scroll compressor in order to satisfy the need of consumer more well.Utilizing communication controlling of MSComm of VB to develop communication software that is realized serial communication of super PC and frequency converter,it can through visual monitoring software to control the gas supply system directly by real-time monitoring and producing or transmitting the control signals.We can realize intelligent contorol and management.This kind of control system of gas supply can improve the properties of system.It is also simple and practical.
