摘要
针对无人智能清扫车系统软件的快速迭代需求,设计了一套车载智能终端软件远程空中下载(OTA)升级方案。该方案涵盖车云通信、车辆升级管理、升级刷写和车辆状态管理等关键模块,采用双向身份验证和超文本传输安全协议(HTTPS)确保通信安全,引入签名验证机制和混合加密技术确保升级数据包的完整可靠。通过搭建试验测试平台,验证了所提方案的有效性。试验结果表明:该系统不仅能够灵活适应不同控制器的升级需求,同时也保证了远程OTA升级过程的安全性与稳定性。
In response to the rapid iteration requirements of the unmanned intelligent cleaning vehicle system software,a set of remote overthe-air(OTA)upgrade solutions for on-board intelligent terminal software has been designed.The solution covers key modules such as vehicle-cloud communication,vehicle upgrade management,upgrade flashing,and vehicle status management.It uses two-way authentication and hypertext transfer protocol secure(HTTPS)to ensure communication security,and introduces signature verification mechanism and hybrid encryption technology to ensure the integrity and reliability of the upgrade data packets.By building an experimental testing platform,the effectiveness of the proposed solution has been verified.The experimental results show that the system can not only flexibly adapt to the upgrade requirements of different controllers,but also ensure the security and stability of the remote over-the-air upgrade process.
