AI Technical Summary

Technical Problem

Passive nuclear level gauges are susceptible to interference during nuclear radiation testing and cannot accurately detect material levels, leading to false alarms, equipment malfunctions, or level monitoring failures, which affect industrial production safety.

Method used

By determining nuclear radiation interference during flaw detection, output protection operations are performed, including setting the switch status, replacing the material level value, or maintaining the original switch status, and generating a replacement material level signal to ensure reliable material level output during flaw detection.

Benefits of technology

During nuclear radiation flaw detection, a stable material level output is provided to avoid false alarms, ensure safe equipment operation, and improve the stability and safety of the production process.

Abstract

The application discloses a passive nuclear material level meter, a material level output control method thereof during nuclear radiation detection, and a monitoring system. The material level output method comprises the following steps: determining whether there is a nuclear radiation detection interference in a measurement environment of the passive nuclear material level meter; and performing at least one of the following output guarantee operations: setting an output switch of the passive nuclear material level meter to a preset guarantee state, wherein the preset guarantee state is an on state or an off state of the switch; or maintaining the output switch of the passive nuclear material level meter in a switch state before the determination that there is the nuclear radiation detection interference; or replacing a normal material level value of the passive nuclear material level meter with a replacement material level value, or determining a switch state of the output switch of the passive nuclear material level meter based on the replacement material level value, wherein the replacement material level value is used to replace the normal material level value when the detection interference is detected, and the normal material level value is a material level value generated based on real-time measurement data in a state without performing the guarantee operation. The application realizes the guarantee control of the material level output during the nuclear radiation detection.
