Problems solved by technology
In the past, the microcomputer excitation systems of generators used serial interfaces or some networks to complete these tasks. Due to the shortcomings of high bit error rate, slow transmission speed, and low anti-interference ability in the serial interface or the network itself, and when several Collisions are likely to occur when the stations send data at the same time, or the system may collapse due to overload, resulting in failure of the generator excitation system, the generator is forced to stop, and the power system is greatly impacted
