【摘要】：为实现农田土壤样本采样及管理智能化,设计了基于3S(GIS:geographic information system;GPS:global positioning system;RS:remote sensing)、ZigBee无线通信、射频识别(radio frequency identification,RFID)、4G等技术的土壤采样智能管理系统,该系统由采集节点、协调器网关、移动终端和远程管理软件组成,其中采集节点用来获取土壤样本的地理位置信息、RFID电子标签数据以及土壤环境的温湿度。协调器网关由ZigBee协调器连接4G模块组成,实现ZigBee无线网络转换为4G网络。4G模块经配置软件配置好服务器IP和端口号等信息后,将采集节点获取的数据传输到远程服务器的管理软件中。通过系统稳定性试验测试,丢包率为0.2%,该系统具有较高的可靠性。移动终端采用掌上电脑PDA(personal digital assistant),实现土样采集的现场监测管理。远程管理软件应用Web、SQL Server(structured query language server)、Socket等技术开发了数据接收显示、百度地图、数据自动成图(2D、3D)等功能模块。利用GPS信息在百度地图中可以实现采样点的实时跟踪,调用数据库数据或者本地试验数据可以自动生成有关土壤信息的空间分布图。该系统采集土壤样本信息的同时也可获取相应的土壤样本养分信息,将土壤养分信息数据按照RFID标签导入土壤管理软件中对应的土样信息栏,生成了土壤养分空间分布图,为后续变量施肥提供决策支持。
[Abstract]:In order to realize intelligent sampling and management of farmland soil samples, a soil sampling intelligent management system based on 3s (GIS: geographic information system), GPS: global positioning system and RS: remote sensing (ZigBee wireless communication, radio frequency identification (radio frequency identification / RFID) 4G is designed. The system consists of acquisition nodes and coordinator gateways. Mobile terminal and remote management software are used to collect the geographic location information of soil samples and RFID tag data and the temperature and humidity of soil environment. The coordinator gateway is composed of the 4G module connected by the ZigBee coordinator. After the ZigBee wireless network is converted to 4G network. 4G module is configured with the software to configure the server IP and port number. The data acquired by the acquisition node is transferred to the management software of the remote server. The system stability test shows that the packet loss rate is 0.2 and the system has high reliability. The mobile terminal adopts PDA (personal digital assistant), to realize the field monitoring and management of soil sample collection. The remote management software has developed the function modules such as data receiving and displaying, Baidu map, data automatic mapping (2DX 3D) and so on using Web SQL Server (structured query language server) socket technology. The real-time tracking of sampling points can be realized by using GPS information in Baidu map, and the spatial distribution map of soil information can be automatically generated by calling database data or local test data. The system can also obtain the soil sample nutrient information while collecting soil sample information. The soil nutrient information data can be imported into the soil sample information bar in the soil management software according to RFID tag, and the soil nutrient spatial distribution map is generated. To provide decision support for the follow-up variable fertilization.
