Thermal meter verification management system and method based on WLAN (wireless local area network)

Abstract

The invention discloses a thermal meter verification management system and method based on a WLAN (wireless local area network). The method comprises the steps as follows: acquiring a unique bar code of a verified thermal meter to call meter information for storage, acquiring key words according to the acquired meter information, matching standard information, an original record and a verification report format, producing corresponding standard values to calculate various error indexes of the meter, generating verification conclusions, and completing management of each verification site. An artificial intelligence based verification management system is constructed by use of the WLAN and wireless equipment, meter verification automation, automatic alarming in case of verification overtime, meter out-of-tolerance alarming management and other functions are realized, the meter verification process is greatly simplified, and the thermal meter verification management system and method have the characteristics that the working efficiency is improved, the labor intensity is reduced and misoperation is reduced.

Description

technical field [0001] The invention relates to the field of measurement verification, in particular to a thermal instrument verification management system and method based on a wireless local area network. Background technique [0002] Thermal instruments (hereinafter referred to as instruments) are commonly used measuring instruments in energy, chemical, steel and other industries. They are classified according to different physical parameters. Common instruments include pressure, temperature, flow, vibration, speed, displacement, etc. In order to ensure the accuracy and reliability of this type of instrument, it is necessary to carry out initial verification and follow-up verification of newly purchased and in-use thermal instruments according to the corresponding verification regulations. [0003] In addition to the necessary technical operations, the work of thermal instruments according to the national verification regulations also requires a large number of data recor...

AI Technical Summary

Problems solved by technology

The original data of instrument verification is manually recorded, the error calculation is performed manually, the verification report is entered and printed manually, and the verification and approval process is manually circulated. All the information of the standard device and the historical data of the device under test need to be checked manually, which is prone to errors, low work efficiency, and labor-intensive. ;

[0006] 2) Low level of management

In the case of many instruments to be inspected, it is impossible to grasp the verification process of the instrument sent by the customer in time, which may easily cause missed or delayed inspection of the customer's instrument and affect the normal production of the customer;

[0007] 3) It is difficult to control the actual operation of the meter under test, which may cause some meters to be used out of tolerance during the verification period. During normal use, the meter will definitely fail to meet the error requirements of the verification regulations for a certain period of time, and the stability is unqualified. To eliminate this type of meter, it is necessary to manually check the data of the previous verification cycle. Obviously, this is extremely inefficient. a job of

[0008] 4) The verification data management is not rigorous enough, and there is a possibility that data entry, error calculation, data modification, etc. do not meet the verification management requirements
