传感器交叉比较存在同向漂移现象的解决方案

The Solution for the Phenomenon of Same Direction Drift in the Cross Comparison of the Sensor

模拟量传感器交叉比较不能检查出传感器同向漂移故障。论文提出三种解决方案,趋势跟踪、不同型号变送器交叉比较、新旧传感器交叉比较,并结合某核电站经验案例进行效果验证。

The same direction drift fault of the sensor can not be detected by simulating the cross comparison of analog sensors. This paper proposes three solutions,trend-following, cross comparison of different types of transmitters, cross comparison between old and new sensors, and combined with the experience cases of a nuclear power plant to verify the effect.
