Cross Comparison Design Analysis of Analog Input Signals of TXS System in Tianwan Nuclear Power Plant

The paper describes and analyzes the mathematical model and structural design of analog signal input redundant channel cross comparison of TXS system in Tianwan Nuclear Power Plant. The operation practice proves that the design of analog signal input redundant channel cross comparison of TXS system can complete well the task of analog signal channel test and channel breakdown tendency monitoring, and it meets the needs of nuclear safety rules and standards.
