Although the existing bus energization monitor can provide convenience for the control of bus cables, it also has some shortcomings in daily use, and the specific shortcomings are as follows:

1. The data line between the main electronic control switch and the remote computer is often very long, which is very susceptible to external interference; once the data line is broken, the remote computer will lose control;

2. Once the bus power-in interface is powered off, the electric control master switch cannot work normally, and the remote computer cannot continue to realize control;

3. When the voltage on the bus input interface is unstable, neither the electric control master switch nor the remote computer can solve this problem;

4. Its function is relatively single, and it can only realize simple one-way control, and cannot provide more convenience and safety guarantee for powering on the bus.
