To solve the actual problems of accurate control of flow and quality during the verification of natural gas, an intelligent metrological verification system applicable to the medium-high pressure gas under the condition of multiple sources was researched and developed, so that the communication barriers between industrial control and data processing system during the original verification process were broken, with the data of multiple systems fused and interconnected with the instructions and interacted in real time, realizing the full intelligent control of verification equipment. With the system, a quality control system platform for standard equipment was established, the variation trend and impact of the deviation of standard equipment were assessed in real time through risk prediction, the performance evaluation business of flow meters was expanded, the operation status of flow meters in the full life cycle was analyzed and evaluated by establishing a multi-dimensional mathematical analysis model, the whole-process remote operation of the operation station control system of the data center was realized by reconstructing the operation mode of verification, and the intelligent assembling and disassembling of instruments with explosion-proof AGV vehicles, explosion-proof mechanical arms, and a customized vision measurement system was explored. Moreover, the prospect was made to the intelligent metrological verification technology of natural gas in the 3 aspects of the online verification and calibration technology, the intelligent upgrading of metering technology, and the industrialized metrological platform.
