The utility model relates to a PWR nuclear power head of a station stick control data collection system, gather the current signal of PWR control rod drive mechanism coil, the outside current signal of being surveyed converts the standard voltage signal into through current -voltage conversion subassembly, signal after the conversion passes through PXI high speed data acquisition card and gathers the PXI controller, the PXI controller carries out the data acquisition and the real time monitoring of measured signal, all historical data that gather store the disk array as the network data server into through network communication UDPFTP mode. The utility model provides a knotty problems of two stick accuse stick position systems, one, the trouble collecting record analysis of feedback current shape information constantly, two, significantly reduced the preceding thread time of cooling the hot test of reactor startup. The utility model discloses can improve accuracy and the rapidity of maintenance personal to failure diagnosis greatly to solve the trouble in the short time, economic benefits also was very obvious when the operation provided and has guaranteed to the long -term safety and stability of PWR nuclear power station.
