Problems solved by technology

However, the detection results output by the detection platform do not match the real detection performance of the rod position system. When the rod position system is officially put into use to detect the rod position, there will be some factors that are difficult to detect by the detection platform. The output bar position information is inaccurate

Abstract

The invention relates to the technical field of nuclear power instrument control, in particular to a detection system of a rod position system, which comprises a rod position table for fixing a rod position detector and a rod position table for mounting a simulation driving rod, the rod position table comprises a support frame and a sliding plate connected to the support frame in a sliding manner, and the simulation driving rod is mounted on the sliding plate. The rack is installed on the supporting frame, the driving device is fixed to the sliding plate, the gear is connected to the driving end of the driving device, and the gear is meshed with the rack. The detection system can simulate the real movement of the driving rod relative to the rod position detector, the rod position system detects the position information of the driving rod, and then the whole process of processing and transmission is carried out. During detection, the gear rotates to drive the movement distance of the simulation driving rod to be compared with rod position information output by the rod position system, so that a more visual, real and comprehensive rod position system detection result compared with the prior art is obtained, and the problems which are difficult to detect in the prior art can be detected easily.

Description

technical field [0001] The invention relates to the technical field of nuclear power instrumentation and control, in particular to a detection system of a rod position system. Background technique [0002] The digital control rod control system and the digital control rod position indication system are both components of the important instrument control system of the nuclear power plant. [0003] Digital control rod control system, referred to as rod control system, its main function is to control the insertion and movement of control rods in the core, so as to realize the start-up, shutdown and power regulation of the reactor. [0004] The digital control rod position indication system, referred to as the rod position system, its main function is to use the rod position detector to detect and obtain the position information of the driving rod connected to the control rod through non-contact electromagnetic induction technology, and the position information of the driving ro...
