Title:
CONTROL ROD OPERATION MONITORING CONTROL SYSTEM
Document Type and Number:
Japanese Patent JP3957869
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To simplify adjusting work for synchro converter by forming a software for the adjusting circuit of the synchro converter which is manually operated.
SOLUTION: Between a control rod drive mechanism 1 inserting and withdrawing control rods by motor drive and having a circuit detecting the position of the control rod from the driven length of the motor and a digital controller 2 controlling the control rod drive mechanism 1, a synchro converter 3 and a control rod position signal adjusting circuit 21 are provided. The control rod position signal adjusting circuit 21 has an input data processor 17, an operating processor 15 and an output data processor 18 connected in series, an automatic data adjusting part 10 connected to the input data processor 17 in series and a synchro conversion reference value preserver 8 connected to the operating processor 15. By this, the adjusting circuit of the synchro converter 3 is formed in software and the adjusting work can be simplified.
