物联网GPRS通信在电能量采控终端中的应用

Application of Internet of Things(GPRS) Communication in Power Acquisition Terminal

为解决传统电能量采集过程中GPRS(通用分组无线业务)无线通信不稳定、数据传输慢的问题,提出在电能量采控终端中应用物联网GPRS通信技术。以内蒙古电力(集团)有限责任公司电能量信息采集与监控系统为例,介绍了电能量数据采集系统原理、构成和通信过程,通过将所采集的电能量信号按固定的报文规约格式制成数据包,利用用户身份识别卡分配的互联网协议地址进行拨号,与基站形成通信传输,并连接相应的网络服务支持节点,再经过物联网GPRS的APN(接入点名称)及端口号通过网关支持节点,连接至电能量信息采集与监控系统上位机,进而完成对数据包的传输,并对该系统的数据传输稳定性和安全可靠性进行了说明。

GPRS data wireless communication is unstable and the speed of data transmission is slow in the electric energy collection process. So Internet of things GPRS wireless communication technology is presented in the power acquisition terminal. The principle of electric energy data acquisition system, composition and the communication process of the electric energy information acquisition and monitoring system in Inner Mongolia Power (Group) Co.,Ltd. is illustrated. Data packet is made from the collected electric energy according to the message protocol and Internet protocol address is assigned using user identification. The system communicates with the base station. Internet of things GPRS APN communicates to the host computer of the electric energy information acquisition and monitoring system through gateway supporting node, and the data packet transmission is accomplished. Results show the stability, the security and the reliability of the data transmission.
