In response to the rapid iteration requirements of the unmanned intelligent cleaning vehicle system software,a set of remote over-the-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.
