摘要
根据现代邮政物流需求,建立了一个邮件变频供件智能控制系统。系统采用OMRON可编程序控制器(PLC)与触摸屏为下位机,IFIX和数据服务程序为上位机。分析了变频供件功能需求,采用Modbus的远程终端(RTU)协议实现PLC与变频器的通信,采用过程控制的OLE(OPC)实现与数据服务程序的数据交互。应用表明,系统实现了邮件变频输送控制自动化和智能化,它的设计方案合理,运行可靠,智能控制效果好。
According to the requirement of modem postal logistics, a kind of intelligent control system for post parcel servo was established. This system was structured by integrated OMRON Programmable Logic Controller （PLC）, touch panel and IFIX supervisory control and data acquisition software. The function of variable-frequency driver for post parcel delivery was analyzed. The communication between PLC and variable-frequency driver was realized by Modbus Remote-Terminal-Unit （RTU） protocol. And the data exchange process was implemented by OLE for Process Control （OPC） and data services program. Application shows that automatic and intelligent control of post parcel delivery has been achieved with variable frequency technology, and the design of control system is reasonable and reliable.
