摘要
研究一种Zigbee通信技术和GPRS通信技术相结合的气象应急监测系统,通过Zigbee技术完成传感器局域组网,实现短距离数据传输;利用GPRS或以太网口接入Internet技术,实现超长距离的通信。鉴于应急监测系统有实时采集参数、移动通信等特点,本系统组建了三层通信结构:1.利用Zigbee技术实现传感器组网的终端;2.接收和处理气象数据的基站;3.远程监测中心。分布在环境中的各个终端设备实时采集由传感器获得的气象数据并通过Zigbee通信技术实时传送数据给基站。便携式基站接受数据并处理数据之后,由基站选择是通过以太网口或是GPRS技术接入Internet,并将数据传送给监测中心。
A meteorological emergency monitoring system is researched, based on combination of the Zigbee and GPRS communications technology. Sensors complete the locality networking by Zigbee technology to achieve shortdistance data transmission, and use the GPRS or the Ethernet connecting the internet to realize ultra-long-distance communication. Emergency monitoring system has real-time acquisition parameters and mobile communication features, the system is set up a three-tier communication structure ： 1. The terminal contains a Zigbee module, so that the sensor builds a local network; 2. The base station collects and real-time processes meteorological data; 3. Center of remote monitor. The terminal located in the environment acquires data is obtained by the sensor and the data are sended to the base station by Zigbee technology. The portable base station receives data by Zigbee module and processes data, then accesses to internet through the Ethernet or GPRS for sending the data to the center of monitor.
