Problems solved by technology

For the circuit of the over-temperature and over-power channel, because the circuit contains a dynamic module, the signal fluctuates greatly when the state of the threshold relay XU is reversed, which leads to the distortion of the XU action value collected by the test bench, which leads to the misjudgment of the test result as a failure

Abstract

An SIP test signal recovery and visualization trend tracking method comprises the steps of: for an over-heat and over-power channel, obtaining a voltage of injection signals of the channel at a firstmoment as a motion voltage of a threshold value relay in the test this time, wherein the first moment is a moment corresponding to a moment of state turning of the threshold value relay to preset time, and the preset time is time required by the state turning of the threshold value relay. The SIP test signal recovery and visualization trend tracking method can overcome the defect that the motion value of the threshold value relay collected by the testbed is distorted and can avoid the erroneous judgement that a test result is not qualified; further, the SIP test signal recovery and visualization trend tracking method sets a test criterion and an early warning value and performs visualization processing to provide richer and more visual test conclusions for operators so as to allow the operators to conveniently pre-determine the test variance which can be possibly generated in advance and discover the hidden danger of channel faults which can be possibly caused in advance; and moreover,the SIP test signal recovery and visualization trend tracking method can rapidly provide board card information corresponding to the test channel, can save time for searching the channel informationand can help the operators with rapid location of the board pieces for renew verification or replacement.

Description

technical field [0001] The invention relates to the field of nuclear power, in particular to a SIP test signal acquisition and visualization trend tracking method. Background technique [0002] SIP (Process Instrumentation System), as part of the nuclear island KRG system, is used to perform necessary processing on the process variables (pressure, water level, flow, temperature, rotational speed, etc.) signals measured by the transmitter, and finally form logic through threshold processing. The protection signal is sent to the RPR (Reactor Protection System) for logical operation (3 out of 2 or 4 out of 2) to form a protection instruction. The SIP system, together with the RPN (nuclear instrumentation system), the RPR system and all the special safety systems (such as RIS, EAS, ETY, etc.), constitute a generalized reactor protection system. [0003] SIP is an important part of the generalized protection system of the reactor, and its failure will directly threaten the safet...
