Metering instrument verification and calibration electronic certificate management platform and method

Abstract

The invention provides a measuring instrument verification and calibration electronic certificate management method, which comprises the following steps of: importing first measuring instrument information on a management platform, and uploading and archiving an external measuring instrument verification certificate scanning copy; second measuring instrument information is imported into the management platform, and an internal measuring instrument verification or calibration electronic certificate is made and issued; electronic certificates can be inquired in real time in each level, and the electronic certificates can be downloaded and printed; the management platform dynamically records the state of the measuring instrument to realize full-life-cycle management and control; the management platform establishes an electronic information file, carries out data analysis and validity period early warning and alarming, and prevents the risk of certificate expiration. The invention further provides a measuring instrument verification and calibration electronic certificate management platform. The method has the advantages that a paperless certificate making and issuing technology is developed, the overdue risk of verification and calibration certificates of the measuring instrument can be effectively controlled, and dynamic control over the whole life cycle of the measuring instrument is achieved.

Description

technical field [0001] The invention relates to the technical field of metrology verification and calibration, in particular to a management platform and method for electronic certificates of verification and calibration of measuring instruments. Background technique [0002] As the terminal platform of refined oil sales companies, gas (gas) stations need to use fuel dispensers, gas dispensers, hydrogen dispensers, diesel vehicle exhaust treatment fluid dispensers, and other Measuring instruments such as fuel filling machines, thermometers, density meters, oil dipsticks, standard metal barrels and horizontal tanks can be measured by external or internal verification or calibration methods according to the different scope of measurement transfer and relevant measurement laws and regulations. Transfer or value traceability, and obtain external and internal measuring instrument verification or calibration certificates. The traditional certificate issuance and management methods...

AI Technical Summary

Problems solved by technology

[0005] According to the quality management requirements for the number of refueling (gas) stations, it is necessary to use refueling machines, gas refilling machines, hydrogenation machines, diesel vehicle exhaust treatment fluid filling machines, other fuel filling machines, thermometers, density meters, dipsticks, standard metal Measuring instruments such as measuring instruments and horizontal tanks, according to the different scope of measurement transfer and relevant measurement laws and regulations, can adopt internal and external verification or calibration methods to realize value transfer or traceability, and obtain internal and external measuring instruments verification and calibration Certificates, each station usually has 4~20 fuel (air) gun external verification certificates, 1~2 thermometer internal verification certificates, 1~2 density meter internal verification certificates, 1~2 oil dipstick internal verification certificates, 1 internal or external verification certificate for a standard metal measuring instrument, 4 to 6 internal calibration certificates for the volume of horizontal tanks, and a provincial large-scale refined oil sales enterprise routinely uses and manages nearly 30,000 measuring instruments, which is very large and difficult to manage Large, especially in the period of 1 to 4 years for the above-mentioned internal verification or calibration of measuring instruments, about 5,000 measuring instrument certificates are issued annually, and the production and use of a large number of paper certificates cause a large amount of resource consumption, which is different from the current state-advocated The concept of green and low-carbon development is incompatible

[0006] (2) The cost of certificate issuance is high

[0007] According to the relevant quantity quality management regulations, non-compulsory verification measuring instruments used in gas (gas) stations must first be submitted for inspection. After verification or calibration meets the standards, a verification or calibration certificate for the corresponding measuring instruments will be issued and received. For inspection units, the traditional method is to issue paper certificates, which consume a lot of manpower, material and financial resources, and have to go through mailing or collection procedures, which is inconvenient

At the same time, certificates of measuring instruments need periodic review and long-term storage. In reality, certificates are often lost due to improper storage, adjustment of management personnel, or change of location. Paper certificates can only be verified on-site, which is not conducive to real-time inspection and filing.

[0008] (3) Poor timeliness of license monitoring

[0009] The verification certificate of external mandatory verification measuring instruments of gas (gas) stations (such as: fuel dispensers, gas dispensers, diesel vehicle exhaust treatment fluid filling machines, and other fuel filling machines) is generally valid for half a year, and the verification period is short. ) Station internal verification or calibration measuring instruments (such as thermometers, density meters, oil dipsticks, standard metal gauges and horizontal tanks) The normal validity period of the verification or calibration certificates ranges from 1 to 4 years, and management personnel need to always pay attention to measuring instruments The status and validity of the certificate, because the base of measuring instruments in the current period is very large, and it is more subject to the time limit of the management personnel's information control, there are problems that the certificate is not found in time, the management time lags, and the certificate is prone to expire, resulting in the risk of illegal use of measuring instruments. Finding a dynamic real-time monitoring method becomes the key to solving the problem

[0010] (4) The life cycle is difficult to track

[0011] According to the relevant data quality management requirements, the measuring instruments used in refueling (gas) stations should be tracked and controlled throughout the life cycle. Check the status of purchasing, warehousing, inspection, use, deactivation, and scrapping of measuring instruments, and check the physical and paper registration information to find out whether there are any abnormalities. It is difficult to quickly retrieve, query, and track information throughout the life cycle

[0012] (5) Lack of support for data analysis

[0016] Problem 1: The refueling (gas) stations of refined oil sales companies use a large number of measuring instruments, the cost of producing and issuing paper certificates is high, it is inconvenient to obtain and use, and consumes a lot of resources, which is contrary to the current green and low-carbon development mode

[0017] Problem 2: The traditional gas (gas) station metering instrument full life cycle management and control adopts a cumbersome way to report layer by layer statistics, lacks timeliness and effectiveness, and is not conducive to dynamic adjustment and monitoring

[0018] Problem 3: Gas (gas) station measuring instruments lack effective informatization and digital supervision methods due to different verification periods, making it difficult to prevent the risk of certificate expiration and rapid statistical analysis of data
