摘要
利用通用分组无线电业务(GPRS)通信技术、可编程逻辑控制器(PLC)和RS-485总线设计了稳定、经济的分布式闸门监控系统。该系统采用Internet/数字数据网(DDN)和GPRS Modem方式接入无线通信网络,并根据闸门监控系统的运行特点,采用GPRS实时通信与短信服务(SMS)通信相结合的方式,不仅保证了系统通信的稳定性和平衡性,且优化了系统的运行成本。最后,对基于GPRS的闸门监控系统的经济性和适用性进行了讨论。
Based on GPRS,PLC and RS-485 Fieldbus,a stable and economical distributed supervisory and control system for sluices is designed.This system is connected to the wireless communication network by GPRS modem and Internet/DDN.Based on the operation characteristics of the system,GPRS real-time communication and SMS communication are used to ensure the stability and equilibrium of the system communication and optimize the operation cost.The economy and applicability of the system are also discussed.
