Background
Along with the scale of the ultrasonic gas meter market is larger and larger, orders of the ultrasonic gas meter are more and more, the pressure of a supply chain for the production and delivery of the ultrasonic gas meter on a larger scale is larger, and due to the structural characteristics of electronic metering of the ultrasonic gas meter, each ultrasonic meter needs to be metered and calibrated before leaving a factory. And sampling the instantaneous flow of each section of flow point in real time through a sonic nozzle metering table, then calculating by comparing the flow of the nozzle to obtain the calibration parameters of the meter, and writing the calibration parameters into the meter so that the metering error of the meter is in an allowable range. However, for the measurement and calibration of the finished product meter used for measurement and calibration at the present stage, the method has the defects that the measurement and calibration parameters are not easy to trace and inquire, the operation process is complicated, the working hours are wasted and the like, and the production and delivery capacity of a manufacturer on a larger scale is limited.
The patent provides a method for metering a base table, calibration parameters can be traced and inquired, the operation is convenient, and the production working hours are simplified.
Disclosure of Invention
Aiming at the defects in the prior art, the invention provides a base meter metering calibration method based on a sonic nozzle metering table.
A base meter measurement calibration method based on a sonic nozzle measurement table comprises the following steps:
step (1), fixedly installing a data acquisition board on a sonic nozzle metering table;
step (2), because the ultrasonic wave base meter is internally provided with the ultrasonic sensor, the processed ultrasonic wave base meter is directly subjected to air leakage measurement without assembling a circuit board and a shell, the base meter number on the label of the base meter is recorded through a scanning gun, and corresponding testing stations are tested;
step (3) supplying power to the ultrasonic sensor of the base meter through the data acquisition board, enabling the ultrasonic sensor of the base meter to work smoothly, starting the metering table of the sonic nozzle, and acquiring instantaneous flow data of the ultrasonic sensor of the base meter through the data acquisition board;
and (4) reading the instantaneous flow on the acquisition board by the sonic nozzle metering table through the photoelectric interface, comparing the instantaneous flow with the gas flow actually sprayed by the sonic nozzle, and then obtaining an error correction parameter of the ultrasonic base meter so that the indication error of the gas meter is within a standard allowable range.
Step (5), uploading the obtained error correction parameters of the corresponding base table numbers to a supply chain MES database system through a sonic nozzle metering table, and writing the metering calibration parameters of the corresponding base table numbers into a meter master control board through a photoelectric instruction after the base tables are made into finished products;
the invention has the following beneficial effects:
1) the existing finished product metering calibration is still unqualified, the finished product metering calibration needs to be scrapped, the metering calibration is carried out in the stage of the base table in advance, the unqualified product metering calibration can be clamped and controlled in the stage, the unqualified base table is prevented from flowing into the next procedure, the metering is found to be unqualified in the stage of the finished product, and labor hour cost and material cost are saved.
2) Compared with the conventional finished product meter integral meter, the base meter metering can improve the production efficiency, does not need to wait for a client to place an order, and can carry out the base meter metering in advance. The whole finished product table cannot be fully utilized due to seasonal changes of production batches and order numbers.
3) And the metering parameters of the base meter metering system in the metering process are convenient to inquire and trace the testing time and the metering data of the base meter through the database connected with the supply chain.
