Abstract

Abstract:

Farm information management system is an important content to realize efficient farm production management. Solving the information management of farm monitoring equipment and agricultural machinery equipment is the key to build farm information management system. In order to solve the problem that the current information management platform is generally difficult to quickly realize the rapid network monitoring and dynamic data analysis of agricultural machinery with different types or different monitoring parameter structures, a digital model synchronization method is proposed based on the distributed architecture idea of "cloud-end", that is, the digital modeling of each different equipment is carried out through the information platform. Relying on specific communication protocols and model update mechanism based on the latest model identification, the vehicle data transmission terminal and platform model synchronization are realized. The vehicle data transmission terminal designed based on the Linux operating system and MQTT protocol provides a general data collector for different types of equipment with different monitoring parameter structures. Analysis of monitoring parameters, local visual monitoring and 4G wireless transmission were carried out. The farm information management platform based on cloud services completed the rapid matching of monitoring equipment parameters and reliable monitoring and analysis of parameter data through digital model update and loading. The integrated data transmission terminal of farming, planting, managing and harvesting equipment was tested. The test shows that the success rate of sending and receiving messages reaches 99.90%, and the monitoring analysis of parameter trend, operation trajectory, and thermal distribution of operation parameters is consistent with the actual operation. The network connection of the system is stable, and it has good stability and scalability.

摘要： 农场信息管理系统是实现农场高效生产管理的重要内容，解决农情监测设备及农机装备的信息管理是构建农场信息管理系统的关键。为解决目前信息管理平台普遍难以快速实现不同类型或不同监测参数结构的农机快速网联监测和动态数据解析问题，基于“云-端”分布式架构思想，提出数字模型同步方法，即通过信息平台对每个不同装备进行数字化建模，依靠特定的通讯规约和基于最新模型标识的模型更新机制，实现车载数据传输终端和平台的模型同步，基于Linux操作系统和MQTT协议设计的车载数据传输终端，提供面向不同类型、不同监测参数结构装备的通用数据采集器，根据平台获取的装备数字模型，进行监测参数解析、本地可视化监测和4G无线传输，基于云服务的农场信息管理平台通过数字模型更新与加载完成监测装备参数的快速匹配和参数数据的可靠监测分析。并对耕、种、管、收4套农机装备集成数据传输终端进行系统测试。试验表明，报文收发成功率达99.90%，参数趋势、作业轨迹、作业参数热力分布等监控分析与实际作业情况一致，系统网络连接稳定，具有较好的稳定性和扩展性较好。
