In order to realize the unattended measurement of the whole process of the whole-body counter of Nuclear Power Station, a complete set of automatic measurement system is designed. The automatic measurement system of the whole-body counter (WBC) covers important functions such as automatic information recognition, management, measurement and analysis. It detects the authority and position of the personnel through the relevant sensors, and controls the speaker and display screen through the personnel identity data and measurement data to guide the personnel to measure orderly and independently. The internal program of the server automatically manages and analyzes the information of the whole system, and finally realizes the storage of effective data and the processing of abnormal state. The results show that the system effectively reduces the cost and human error of the individual dose detection process, improves the work efficiency and measurement accuracy, and successfully realizes the internal pollution detection process of personnel autonomy and equipment automation.
