Background

The current common use of ultrasonic speed gas meters is sonic nozzle meter calibration equipment, which outputs gas stably according to a set flow and a set accumulation amount, and then compares the output gas with the accumulation amount obtained by meter end measurement, thereby obtaining a measurement error and correcting the flow. The table-side accumulated quantities are typically obtained by table-side LED pulses, each LED pulse representing a certain accumulated quantity. And after the output of the flow is stopped, calculating an error according to the cumulant output by the equipment and the cumulant collected to pass through the meter end to generate a correction parameter, and then correcting the meter end.

When the LED pulse acquisition accumulated quantity is used for flow calibration, each LED pulse represents a certain gas accumulated quantity, and when the gas accumulated quantity accumulated at the meter end is less than the accumulated quantity represented by the LED pulse, the pulse cannot be output, so that the gas is ignored, and the accuracy of flow calibration is reduced.

The embodiment of the application provides a correction method and device of an ultrasonic instrument, electronic equipment and a storage medium. The method provided by the embodiment of the invention can be applied to any required electronic equipment, for example, the electronic equipment can be electronic equipment such as a server and a terminal, and the method is not particularly limited herein, and is hereinafter simply referred to as electronic equipment for convenience in description.

According to an aspect of the embodiments of the present application, there is provided an embodiment of a method for correcting an ultrasonic meter, and fig. 1 is a flowchart of a method for correcting an ultrasonic meter provided in an embodiment of the present application, as shown in fig. 1, the method includes:

in step S11, a first accumulated amount of the target meter to be corrected at the target flow rate value is acquired.

The method provided by the embodiment of the application is applied to a control terminal, and the control terminal is used for controlling the fluid output equipment to output flow of a target instrument to be corrected and acquiring cumulant on the target instrument so as to perform calibration operation according to the cumulant. The specific process is as follows:

in the embodiment of the present application, as shown in fig. 2, the step S11 of obtaining the first accumulated amount of the target meter to be corrected at the target flow rate value includes the following steps a1-a 4:

and step A1, sending a control instruction to the fluid output equipment so that the fluid output equipment outputs the flow according to the target flow value carried by the control instruction.

In the embodiment of the application, the control terminal firstly obtains calibration configuration information, wherein the calibration configuration information includes a target flow value, preset detection time, a preset accumulated amount output by the fluid output device, and an error range, the flow point may be a minimum flow, a boundary flow and a maximum flow, the detection time is related to the size of the flow point, and the larger the value of the flow point is, the shorter the detection time is.

After the control terminal determines the meter calibration configuration information, a first control instruction is generated according to an execution flow point carried by the meter calibration configuration information so as to control the fluid output equipment to output flow according to the target flow value.

Step A2, detecting the flow state of the flow output by the fluid output device.

In the embodiment of the application, the output end of the fluid output equipment is detected, information such as temperature change amplitude, flow rate and the like of the output end is determined, and the flow state is determined according to the temperature change amplitude and the flow rate.

And step A3, sending a first reading instruction to the target instrument under the condition that the flow state is in a stable state, so that the target instrument feeds back the first accumulated amount to the control terminal according to the first reading instruction.

Step a4, a first accumulated amount of target meter feedback is received.

In the embodiment of the present application, it is determined that the flow rate state is in the steady state in the case where both the temperature change service and the flow rate speed reach the steady values. At this moment, the control terminal sends a first reading instruction to the target instrument so that the target instrument sends the currently displayed accumulated quantity on the instrument to the control terminal according to the first reading instruction, and the control terminal determines the received accumulated quantity as the first accumulated quantity.

And step S12, acquiring a second accumulated quantity of the target instrument under the condition that the monitoring index corresponding to the target flow value reaches a preset threshold value.

In the embodiment of the present application, the monitoring index includes: the time of flow detection or cumulative amount of fluid output by the fluid output device.

Based on this, in the case that the monitoring index is the flow detection time, and in the case that the monitoring index corresponding to the target flow value reaches the preset threshold, obtaining a second cumulative amount of the target meter, includes: and under the condition that the flow detection time corresponding to the target flow value reaches the preset detection time, determining the cumulant displayed by the target instrument in the preset detection time as a second cumulant.

As an example, when the monitoring indicator is the flow detection time, the control terminal may use a time when the flow state is in the stable state as a start time, and at this time, the control terminal may start timing until the preset detection time is reached. And when the preset detection time is reached, the target instrument sends the cumulant displayed during the preset detection time to the control terminal, and the control terminal determines the cumulant as a second cumulant.

In this embodiment of the present application, in a case that the monitoring index is an accumulated amount, and in a case that the monitoring index corresponding to the target flow rate value reaches a preset threshold, obtaining a second accumulated amount of the target meter includes: and determining the currently displayed accumulated amount of the target meter as a second accumulated amount when the accumulated amount output by the fluid output device reaches a preset accumulated amount.

As an example, when the monitoring index is an accumulation amount, the control terminal monitors the accumulation amount of the fluid output device, and when the accumulation amount output by the fluid output device reaches a preset accumulation amount, the control terminal sends a reading instruction to the target meter to obtain the accumulation amount displayed by the target meter when the accumulation amount reaches the preset accumulation amount, and determines the accumulation amount as a second accumulation amount.

In step S13, a calculation is performed based on the first accumulation amount and the second accumulation amount to obtain correction data.

In the embodiment of the present application, as shown in fig. 3, when the monitoring index is the flow rate detection time, the step S13 of calculating based on the first accumulated amount and the second accumulated amount to obtain the correction data includes the following steps B1-B4:

and step B1, sending a second reading instruction to the target instrument, so that the target instrument feeds back a third accumulation amount displayed by the target instrument at the final time to the control terminal according to the second reading instruction, wherein the final time is the time when the target instrument data receives the second reading instruction.

In the embodiment of the application, when the control terminal determines that the monitoring index reaches the preset threshold, a second reading instruction is generated and sent to the target instrument, after the target instrument receives the second reading instruction, the final time for receiving the second reading instruction is determined, the cumulant displayed by the target instrument in the final time is sent to the control terminal, and the cumulant is determined as a third cumulant by the control terminal.

It should be noted that there is a delay from the generation of the second read command by the control terminal to the reception of the second read command by the target meter, or a delay in reading may be caused by other accidents. Therefore, the embodiment of the application can subsequently correct the target meter by utilizing the accumulated quantity generated in the delay process.

Step B2, a first difference between the first accumulation amount and the second accumulation amount, and a second difference between the third accumulation amount and the first accumulation amount are determined.

In the embodiment of the present application, the first accumulation amount is taken as V1, the second accumulation amount is taken as V2, the third accumulation amount is taken as V3, the first difference V4 between the second accumulation amount V2 and the first accumulation amount V1 is calculated, and the second difference V5 between the third accumulation amount V3 and the first accumulation amount V1 is calculated.

And step B3, calculating the ratio of the first difference to the second difference to obtain a correction parameter.

In the embodiment of the present application, the ratio between the second difference V5 and the first difference V4 is calculated, and the ratio is used as the correction parameter.

And step B4, calculating the ratio of the second difference to the final time to obtain the corrected flow.

And step B5, determining the correction parameters and the correction flow as correction data.

In the embodiment of the present application, the final time is denoted as T1, and the ratio of the second difference V5 to the final time T1 is determined as the corrected flow rate. After the corrected flow rate is obtained, the correction parameter and the corrected flow rate are determined as correction data.

As an example, the control terminal sends a control command to the fluid output equipment, and the flow point carried in the control command is 0.04m³H, after the fluid output equipment reaches the stable state, the control terminal sends the fluid output equipment to the target instrumentThe first reading command is used for obtaining a first accumulated amount V1, at which time V1=1.275m, and during the beginning of the flow output timing, when the flow output time reaches the preset output time (900 s), the second accumulated amount V2 displayed by the target meter when the preset output time is reached is carried out, at which time V2=1.284 m. And the control terminal sends a second reading instruction to the target instrument, and if the first sending of the second reading instruction fails, the second reading instruction is sent again. After receiving the second read command, the target instrument determines a final time (901 s) for receiving the second read command, and sends the accumulated amount displayed by the target instrument in 901s to the control terminal, and the control terminal takes the accumulated amount as a third accumulated amount V3, at this time, V3=1.285m for cultivation, and the correction parameter is 1.111, and the correction flow is 0.0399m for cultivation/h, and the correction parameter is: 1.111 and correction flow: 0.0399 m/h are determined as corrected data.

In another embodiment of the present application, when the monitoring index is an accumulated amount, the step S13 of calculating based on the first accumulated amount and the second accumulated amount to obtain the corrected data further includes the following steps C1-C5:

step C1, obtaining an actual output time required for the cumulative amount of fluid output by the fluid output device to reach a preset cumulative amount.

And step C2, calculating the average flow rate in the actual output time, and determining the average flow rate as the corrected flow rate.

Step C3, calculating the product of the corrected flow rate and the actual output time, and the difference between the first accumulated amount and the second accumulated amount.

Step C4, calculating the ratio between the product and the difference, and determining the ratio as the correction parameter.

Step C5, determining the correction parameters and the correction flow rate as the correction data.

As an example, the control terminal sends a control command to the fluid output device, the flow rate point carried by the control command is 0.04m for cultivation/h, after the flow rate output by the device is stabilized, the control terminal reads the first accumulated amount V1 of the target instrument, where the first accumulated amount V1 is 0.998531m for cultivation, and sends a command to the calibrated instrument to read the accumulated amount V2 of the meter when the accumulated amount output by the device reaches 10L, where V2 is 1.009118m for cultivation, and when the actual output time of the flow rate output is 900s, the average flow rate within 900s is 0.04002m for cultivation/h, and the average flow rate is determined to be 0.04002m for cultivation/h.

Then calculation of 0.04002 m/h × (900 ÷ 3600) h ÷ (1.009118-0.998531 m) thin plant

0.94503 is obtained as a correction parameter.

In step S14, the correction data is written into the target meter so that the target meter is corrected in accordance with the correction data.

In the embodiment of the application, the correction data is written into the target meter, so that the target meter completes flow correction according to the correction data. Wherein the correction data includes: correction point 1, correction flow q1 and correction parameter F1; correction point 2, correction flow q2, correction parameter F2; correction point 3, correction flow q3, correction parameter F3, and so on.

According to the method and the device for calibrating the flow, the flow calibration is carried out by a method of reading the first cumulant and the second cumulant through the monitoring indexes, so that the problem that the gas cumulant of the LED pulse meter calibration is neglected is solved, and the flow calibration efficiency can be improved.

In the embodiment of the present application, as shown in fig. 4, after the correction data is written into the target meter, the method further includes the steps of:

in step S21, the corrected target meter is checked, and the error of the corrected target meter is calculated.

And step S22, confirming that the target instrument is corrected to pass under the condition that the error falls into the preset error range.

In the embodiment of the present application, after the correction list is written into the meter to be corrected, the corrected meter needs to be checked to ensure that the error of the corrected meter is within the specified range. The operation flow during the test is consistent with the operation flow for generating the correction parameters, except that the test of the instrument needs to calculate errors instead of the correction parameters, and the calculation process of the errors is as follows:

a first difference V4 between the second accumulated amount V2 and the first accumulated amount V1 and a second difference V5 between the third accumulated amount V3 and the first accumulated amount V1 are obtained, a difference between V4 and V5 is calculated, and a ratio between the difference and V5 is calculated, which is determined as an error.

And then, comparing the calculated error with an error range (such as +/-3%, +/-2% and the like) required by the flow calibration scheme table, and if the error is within the error range, checking to be qualified, and if the calculated error does not belong to the error range, checking to be unqualified. And clearing the correction list in the table to execute the correction process again for the table which is not qualified by the inspection until the inspection is qualified.
