This paper proposes a queue loop optimization algorithm to remove explicit redundancy completely which decreases the circuit area and improves the testability.
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。

A distributive configuration PLC system was used as control terminal of the detection device, while a relay loop as a redundancy control system.
