摘要
目前现有的农作物生长环境检测仪表功能单一,当需要同时测量多个参数时,仪表之间无法联机,采集数据的记录处理非常麻烦。针对以上问题,设计了基于Zigbee的土壤水分测量系统,可同时测量土壤水分、土壤温度、环境温度、环境湿度及光照强度。终端节点采用电池供电,可以很方便的进行传感器的部署。终端节点采到各类传感器的数据后通过Zigbee网络发送到协调器,协调器再通过ModBus协议将各个终端的数据发送到电脑,再通过利用Labview编写的上位机软件对数据进行分析处理。系统采用Zigbee无线组网,可以很方便地加入其他如二氧化碳浓度、土壤盐分含量等参数的测量功能。测试结果表明,开发的系统测量精度高,成本低,可满足对农作物生长环境的监测。
At present,the existing crop growth environment detection instruments have single function.When multiple parameters need to be measured at the same time,the instruments can not be online,so the recording and processing of collected data is very troublesome.Aiming at the above problems,a soil moisture measurement system based on ZigBee is designed,which can measure soil moisture,soil temperature,environmental temperature,environmental humidity and light intensity at the same time.The terminal node is powered by battery,which is convenient for sensor deployment.The terminal node collects the data of various sensors and sends them to the coordinator through ZigBee network.The coordinator sends the data of each sendpoint to the computer through the Modbus protocol,and then analyzes and processes the data through the host computer software written by LabVIEW.ZigBee wireless network is adopted in the system,and other parameters such as carbon dioxide concentration and soil salt content can be easily added into the system.The test results show that the developed system has high measurement accuracy and low cost,and can meet the monitoring of crop growth environment.
