一种终端接入网络的方法及系统
By using a visible light communication processor to determine the consistency of array positioning, imaging positioning, and network positioning results of industrial control network terminals, a key exchange mechanism is established. This solves the problem of difficulty in identifying illegal terminals caused by the uncertainty of terminal positions in industrial control networks, and achieves secure and reliable authentication and control.

AI Technical Summary
In industrial control networks, the uncertainty and scalability of terminal network locations make it impossible to accurately identify illegal terminals and effectively utilize location and motion information for authentication negotiation and security control.
The visible light communication processor obtains the array positioning results, imaging positioning results, and network positioning results of the terminal, establishes the first valid point set using consistency judgment, obtains the key, and performs encrypted information verification to ensure that the legitimate terminal communicates with the visible light communication network.
It improves the accuracy of identifying unauthorized terminals, enables effective authentication negotiation and security control, and enhances the security of industrial control networks.
