一种基于GPS和GIS农业装备田间位置的监控系统

对田间车辆的实时监控和导航，是实施精细农业变量作业技术的基础。该文结合中国国情和旱作农业的实际，将GPS、GIS技术相结合，采用MapInfo公司生产的MapX4.5控件内嵌可视化编程语言Visual Basic 6.0，研制开发了一种基于GPS和GIS的田间农业装备实时监控和信息管理系统。系统完成了地图常用功能和各种GIS工具模块的设计,包括串口通讯、地图编辑、网络通讯3个子系统，共17个模块，本系统采用控件技术设计了串口和网络的数据传输和传输数据的保存；以旱作农业机械为例，建立了动态田间农业机械装备数

Field vehicle position monitoring system based on GPS and GIS

In order to implement variable-rate technology in precision agriculture, it is essential to monitor and guide field vehicles in real time. In this paper, according to the actual conditions and the characteristics of dryland farming in China, a real time monitoring and management system based on GPS and GIS was developed using MapInfo Company's MapX4.5 ActiveX Control with Visual Basic 6.0. Common electronic map functions and various GIS tool modules were designed, including serial interface communication, map edition and network communication, a total of 17 modules. Control technology was used to design the serial interface and network to realize data transmitting and saving. Using dryland farm equipment as an example, a dynamic database and a query system for farm machinery were established. With the electronic map editing and real time monitoring, the system can determine and display the equipment location in the field, and can also perform data processing and management. Results from PC-PC testing show that the system has powerful functionality, good expandability and high practicability, and succeeds in combining dynamic monitoring with static analysis. This system provides a platform for further research on variable-rate application of intelligent agricultural equipment.
