Pressure vessel monitoring system and monitoring method thereof

Abstract

The present invention relates to a pressure vessel monitoring system and a monitoring method thereof. The system includes a fiber grating sensing device, a data collection device, a remote server, andan alarm device which are connected in sequence. The fiber grating sensing device is installed in a pressure vessel, and detects temperature and pressure of the pressure vessel to generate detectionresults, the results are sent to the data collection device and summarized, then the results are sent to the remote server for analysis to obtain an analysis result, and when the analysis result meetspreset alarm conditions, an alarm command is sent to the alarm device to give an alarm. No electrical interference is caused during detection. The data collection device improves the data transmission efficiency. The remote server implements remote data processing. When the analysis result meets the preset alarm condition, the alarm command is sent to the alarm device to alert the operator to deal with the abnormal situation in time. The operator can remotely receive data and alarm information to avoid the pressure vessel itself or the environment from adversely affecting the operator. The system and the method are convenient to use and highly reliable.

Description

technical field [0001] The present application relates to the technical field of monitoring and early warning systems, in particular to a pressure vessel monitoring system and a monitoring method thereof. Background technique [0002] A pressure vessel refers to a closed device that holds gas or liquid and carries a certain pressure, and is widely used in various industrial equipment. In the field of nuclear power, pressure vessels include reactor pressure vessels, main steam generators, main pipelines, and pressurizers. These pressure vessels are an important part of nuclear power generation. The state is the basis for ensuring the normal operation of nuclear power equipment, so the monitoring of its working state is very important. [0003] Traditional pressure vessel monitoring methods mainly use piezoelectric sensors to detect pressure and temperature sensors to detect vessel temperature, and then process the detected pressure and temperature information and display the...
