摘要
针对传统的移动测控系统的监控实时性差、成本高等问题,结合ZigBee技术和GPRS技术,设计了一种基于ZigBee和GPRS的多通讯功能无线测控系统.该系统由实现就地采集和控制的传感器节点、路由器和ZigBee协调器等组成,传感器节点采用MC56F8037 DSP芯片进行数据采集和控制,采用JN5139芯片实现ZigBee通讯,两芯片之间采用串行通讯交换数据;协调器节点主要由JN5139芯片、以太网芯片CP2200和SIM900A模块组成.协调器除管理ZigBee网络外,实现了与以太网控制芯片CP2200通讯,嵌入了GPRS通讯协议、以太网协议和TCP/IP协议,使之成为具有多种接口的多功能网关,实现了基于Internet的远程控制.研究结果表明,该系统减少了多种通讯方式下的转发设备,降低了成本投入,为基于无线通讯的远程监控系统提供了实用和高效的解决方案,具有广阔的市场前景.
Abstract
Aiming at the shortcomings existing in traditional mobile measurement and control system,such as real-time problem and high cost,a multifunctional wireless measurement and control system based on ZigBee and GPRS was designed combining the ZigBee and GPRS technology..The system is compose of sensor node with local measurement and control function,router and coordinator.In the sensor node MC56F8037 was adopted for measurement and control,JN5139 was adopted for ZigBee communication,and series communication was used to exchange data between two components.The coordinator is composed of JN5139,CP2200 and SIM900A module.The multi-interface was implemented in the coordinator besides management of ZiBee network with embedded Ethernet protocol,GPRS protocol and TCP/IP protocol for control based on Internet.The results indicate that the system provides the practical and effective solution for remote monitoring and control with low price and broad market prospects.
