Design of interactive electronic technical manual for the thermohydraulic measuring instruments of nuclear power plant

The interactive electronic technical manual of thermohydraulic measuring instruments of nuclear power plant(NPP) was designed to improve the capacity of the fault detection and maintenance technical support by integrating the technique of visual, fault tree analysis, fault recognition, database management and fuzzy query. The general method and procedure for fault detection of thermohydraulic measuring instruments are provided, and the fault mechanism of thermohydraulic measuring instruments is included in this manual. The schematic circuit diagram of thermohydraulic measuring instruments and its frequent faulty phenomena and faulty part are also included. The approach of fault detection and maintenance that is most important in the fault detection and maintenance process is presented in visual and interactive way. The manual is of functions of teaching, fuzzy inquire, add data, noting and print. The interface of man-machine is favorable. The results reveal that employing the designed manual can improve the capacity of fault detection and maintenance technical support of thermohydraulic measuring instruments of nuclear power plant.
