Intelligent multi-channel verification system and verification method

Abstract

The invention relates to an intelligent multi-channel verification system, which comprises at least one gas path for providing a gas pressure source and a working medium for verification. The gas pressure source provides pressure for the working medium. The intelligent multi-channel verification system is characterized in that the system further includes at least one standard pressure gauge whichis connected with an automatic switching range group valve and at least one verified pressure gauge, and a corresponding image collection element is arranged for each verified pressure gauge; pressuresignals representing the indicating values of the standard pressure gauges are converted by a pressure controlled into signals which can be read by a control system; and the image collection elementscollect the dial images of the verified pressure gauges and transmit the dial images to the control system for processing, so as to calibrate the verified pressure gauges. The invention further discloses a verification method. A series of work, such as intelligent verification, automatic collection of data through images, automatic report generation, network barrier-free verification certificateand management of a data transmission system, can be completed. An important contribution is made to more efficient verification of pressure gauges.

Description

technical field [0001] The invention relates to a verification system and method, in particular to an intelligent multi-channel verification system and a verification method. Background technique [0002] The pressure gauge is a measuring instrument widely used in safety protection. Among them, the elastic element type general pressure gauge is a compulsory verification measuring instrument that can be directly used in safety protection and listed in the national compulsory verification catalog. Calibration of a pressure gauge, that is, the method of calibrating a pressure gauge through a pressure source and a single standard. This method is slow in verification and low in efficiency. A single verification unit is mostly used to trace the source of the value. The structure of the measurement standard is simple, the operation method is primitive, and the verification efficiency is extremely low. [0003] Therefore, it is urgent to research and develop a multi-channel pressur...

[0002] The pressure gauge is a measuring instrument widely used in safety protection. Among them, the elastic element type general pressure gauge is a compulsory verification measuring instrument that can be directly used in safety protection and listed in the national compulsory verification catalog. Calibration and calibration of a pressure gauge, that is, a method of calibrating a pressure gauge through a pressure source and a single standard calibration. This method is slow in verification speed and low in efficiency. It relies heavily on manpower in terms of pressure creation and reading, and there is almost no intelligence at all. A single verification unit is mostly used to trace the source of the value. The structure of the measurement standard is simple, the operation method is original, and the verification efficiency is extremely low.
