It shows that the self-pumping type and pump-probe types bistable switching can both be realized in the same structure, and the latter can separate the pump and signal in frequency and space.
Be the adoption of redundancy optimization, self-designed adjustable installation structure of loop coder, redundancy switching and fault warning functions of the loop coder were developed.
采用冗余优化，自行设计实施活套编码器可调式的安装结构，开发出活套编码器的冗余切换和故障报警功能。

It can not only be of direct switching function, but self-locking switching function.
