Radiation Resistance Experiments of Image Sensor and Acoustic Sensor
With the development of the nuclear power and the requirement of the nuclear power equipments automation,the fault diagnosis system needs to vibration,noise,temperature and other signals generated by the sensor acquisition system under test.Monitoring technology in high radiation environment is very different from traditional monitoring technology,there is a high radiation resistant performance to sensors,amplifying circuit and transmission cable.The project group preliminary study results show that using sound detection method for real-time video monitoring to get more equipment operating information.According to the research in radiation effect of semiconductor devices and comparison experiment,radiation resistant performance of moving-coil acoustic sensor is above CMOS image sensor several orders of magnitude.This provides a powerful hardware support to it that fault diagnosis method based on capturing the audio signal while the nuclear facilities are operating is proposed.
