摘　　要：基于ZigBee技术的低功耗水文遥测系统,利用感知层内的遥测雨量计、管道流量计、浮子水位计获取当前流域水文信息后,经由RS485总线将其传输到控制层内的遥测数传仪内,再将水文RS485总线信息转换成报文后,将其发送到传输层内ZigBee收发器内;传输层按照水文报文信息属性利用ZigBee无线网络和5G通信传输技术将其传输到相对应的组网内,并传输到服务层内;服务层利用防护墙过滤水文报文信息后,经由服务器将其存储于数据库内,用户通过调取数据库内水文报文信息,对流域水文异常情况进行识别并使用水文地图展示功能呈现当前水文异常状态,完成遥测。实验表明,该系统稳定性好,应用效果显著。A low power hydrological telemetry system based on ZigBee technology is studied. After the current hydrological information of basin is obtained by using the telemetry rain gauge, pipeline flowmeter and float water level gauge in the sensing layer, it is transmitted to the telemetry data transmitter in control layer through RS485 bus, and after the telemetry data transmitter converts the hydrological RS485 bus information into the tipping pulse GPRS300 to compile the message, the hydrological message information is sent to the ZigBee transceiver in the transmission layer. According to the hydrological message information attribute, the transmission layer uses ZigBee wireless network and 5 G communication transmission technology to transmit it to the corresponding network, and then transmits the hydrological message information to the service layer. The service layer uses the protective wall to filter the hydrological message information, and stores it in the database through the server. The user can identify the hydrological anomaly of the basin by retrieving the hydrological message information in the database, and use the hydrological map display function to present current hydrological anomaly status, so as to complete the hydrological telemetry process. The experiment shows that the system has good stability, and the application effect is remarkable.
