The technology of rail transit is developing fast, as more and more auto-control systems are applied to the rail transit system, the operation efficiency and speed is well improved.

Along with the technology development, lots of high-precision and high-speed processing systems are used, the working voltage is getting lower, the anti-interference ability of the system is greatly reduced, and the system security becomes fragile. In operation, due to lightning invasion, power system failure, the over-voltage caused by the complex electromagnetic environment, the systems might be working in risks.
