【摘要】 针对目前自动导航插秧机通过车载终端进行路径规划,不能灵活、实时调整路径的不足,基于云技术和移动物联网技术,构建无人驾驶插秧机远程路径规划系统。该系统由云服务器、远程规划终端和本地终端3部分组成,云服务器和远程规划终端构成云平台,本地终端包括无人驾驶控制器、手持终端和智能手机,服务端与客户端之间通信基于TCP/IP协议。为减少对网络资源的占用时间,对需要实时通信的网络节点采用MQTT协议,采用查询方式即可访问的网络节点则采用HTTP协议。搭建快速测试系统对基于云平台的远程路径规划系统进行验证,测试结果表明:该系统信息传输稳定,操作方便灵活,能够实时、动态地对路径进行规划和调整。更多还原

【Abstract】 Aiming at the problem that the automatic navigation rice transplanter cannot adjust the path flexibly and in real-time through the vehicle terminal, the remote path planning system of the unmanned rice transplanter is constructed based on cloud technology and mobile Internet of Things technology. The system consists of three parts, including cloud server, remote planning terminal and local terminal. The cloud server and remote planning terminal constitute the cloud platform. The local terminal includes unmanned driving controller, handheld terminal and smart phone. The communication between server and client is based on TCP/IP protocol. In order to reduce the time of using network resources, MQTT protocol is used for network nodes that need real-time communication, and HTTP protocol is used for network nodes that can be accessed by query. A quick test system is built to verify the remote path planning system based on cloud platform. The test results show that the system has stable information transmission, convenient and flexible operation, and can plan and adjust the path in real-time and dynamically.更多还原
