摘　　要：为了满足农田信息采集与智能水利检测技术的发展,进一步优化现有的智能监测水渠水利系统,设计了一套基于NB-IoT的农业灌溉水渠远程监测系统,系统包含监测节点、NB-IoT通信模块和远程服务器三部分;监测节点采用STM32F103RCT6为微控制器,定点采集所在位置的农田信息与灌溉水渠信息,并通过NB-IoT通信模块发送至远程服务器;远程服务器一方面解析接收的参数信息,实现数据显示与地图定位等功能,另一方面将接收的参数信息保存至TXT文件中,便于后续数据分析与历史查询等操作;在远程服务器设置参数阈值信息,可以反馈至监测节点完成预警判断与远程报警;测试结果表明:监测节点以3小时为时间间隔进行一次参数采集,参数信息到达远程服务器的时间差控制在80 ms以内,地图显示的定位误差在2 m以内,达到了系统设计的参数要求,为水渠水力智能化监测提供了有力保障。In order to meet the technology development of farmland information collection and intelligent water conservancy detection,and further optimize the existing intelligent monitoring system of canal water conservancy,a set of remote monitoring system for agricultural irrigation canals based on the NB-IoT is designed.The system includes three parts:monitoring node,the NB-IoT communication module and remote server.The monitoring node adopts the STM32F103RCT6 as the microcontroller to collect the farmland information and irrigation channel information at the fixed time point,and sent it to the remote server through the NB-IoT communication module.On the one hand,the remote server parses the received parameter information,the functions such as data display and map positioning are realized.On the other hand,the remote server saves the received parameter information to the TXT file,which is convenient for operations of subsequent data analysis and historical query.The parameter threshold information can be set on the remote server,which can be fed back to the monitoring node to complete early warning judgment and remote alarm.The test results show that the monitoring node collects parameters once at an interval of 3 hr,the time difference of parameter information reaching the remote server is controlled within 80 ms,and the positioning error displayed on the map is within 2 m,which meets the parameter requirements of the system design and provides the strong guarantee for the intelligent monitoring of canal hydraulics.
