Problems solved by technology

[0002] Referring to the Chinese patent document CN201310648117.6, a control rod position linear measurement system and method are disclosed. The hardware circuit is used to measure the position of the control rod, and its accuracy and stability completely depend on the electronic components of the hardware circuit, so that the control rod The accuracy of the position measurement is not enough, affecting the linear measurement of the control rod position
[0003] On the other hand, when measuring the rod position of the control rod, if the signal of the given rod position is wrong, the actual rod position of the control rod will be affected by fluctuations. When the error occurs, the abnormality may be treated as normal, or the normal signal may be mistaken for abnormality, and the accuracy of the measurement result is poor.

Abstract

The invention discloses a static rod position linearity measurement method for a control rod of a nuclear power plant. The method comprises following steps: measured rod position signals and given rodposition signals of the control rod of a reactor are collected in real time; the collected measured rod position signals and given rod position signals are processed, the processing comprises steps as follows: whether the measured rod position signals have directional jump or not is judged, if yes, the measured rod position signals and the given rod position signals with jump are removed by filtering, rod position difference between the measured rod position signals and the given rod position signals after filter processing is calculated, so that a linearity table of the whole control rod movement process is obtained, and the measurement is accurate. The invention further discloses corresponding electronic equipment and readable storage media.

Description

technical field [0001] The invention relates to a static rod position linearity measurement technology, in particular to measuring the rod position linearity in the entire moving rod period of the control rods in a nuclear power plant reactor, and automatically giving the linearity judgment result of each group of control rods. Background technique [0002] Referring to the Chinese patent document CN201310648117.6, a control rod position linear measurement system and method are disclosed. The hardware circuit is used to measure the position of the control rod. The accuracy and stability of the control rod completely depend on the electronic components of the hardware circuit, so that the control rod The accuracy of the position measurement is not enough, which affects the linear measurement of the control rod position. [0003] On the other hand, when measuring the rod position of the control rod, if the signal of the given rod position is wrong, the actual rod position of t...
