Problems solved by technology

In the prior art, a fixed integration period (that is, a fixed frequency) is often used to measure the measurand. If the integration period is shorter, although the measured value obtained by integration is closer to the real value, it will cause a problem of high power consumption; The integration period is long, although it will not cause a burden on power consumption, but it will lead to low accuracy of the measured value obtained by integration

Embodiment 1

[0023] Such as Figure 1a As shown, it is a schematic flow chart of the method for dynamically adjusting the meter measurement frequency provided by Embodiment 1 of the present invention, which may include the following steps:

[0024] S11. When using a meter to measure the object to be measured, acquire a meter indication of the meter at a current measurement frequency.

[0025] During specific implementation, the measurement indication of the meter can be obtained through wireless transmission. For example, the billing platform and the meter agree on the reporting time in advance. For example, the meter needs to report the measurement indication of the meter to the billing platform every 5 minutes. Therefore, when the time preset time arrives, the meter will report the metering number of the meter to the billing platform in a wireless manner, or the meter can also report the metering number of the meter in other ways, which is not covered by the present invention. To limit. ...

Embodiment 2

[0076] Based on the same inventive concept, the embodiment of the present invention also provides a device for dynamically adjusting the measurement frequency of meters. Since the problem-solving principle of the above-mentioned device is similar to the method for dynamically adjusting the measurement frequency of meters, the implementation of the above-mentioned device can be found in the method The implementation of this method will not be repeated here.

[0077] Such as figure 2 As shown, it is a schematic structural diagram of a device for dynamically adjusting meter measurement frequency provided by Embodiment 2 of the present invention, including an acquisition unit 21, a determination unit 22, and an adjustment unit 23, wherein:

[0078] The acquiring unit 21 is configured to acquire the measurement indication of the meter at the current measurement frequency when the meter is used to measure the measured object;

[0079] A determining unit 22, configured to determine...

Abstract

The invention discloses a method and device for measuring frequency by dynamically adjusting a gauge table. The method comprises the steps of when using the gauge table to measure an object to be measured, acquiring a measurement display value of the gauge table at the current measurement frequency; determining a difference value between the measurement display value of this measurement and a historical weighted average value before this measurement; according to the difference value, adjusting the measurement frequency of the gauge table. By the adoption of the method, the measurement frequency of the gauge table can be adjusted in real time according to a current measurement result, not only can the measurement precision of the gauge table be guaranteed, but also the power consumption generated by the gauge table can be effectively reduced.

Description

technical field [0001] The invention relates to the technical field of instruments and meters, in particular to a method and a device for dynamically adjusting the measurement frequency of a meter. Background technique [0002] With the development of meter technology, meter intelligence is getting higher and higher. Taking ultrasonic flowmeter as an example, ultrasonic flowmeter has been widely used in the measurement of natural gas, petroleum gas and coal gas, and is also widely used in various Measurement of liquids. The essence of ultrasonic flowmeter measurement is to integrate the measured value, so the integration period needs to be considered. In the prior art, a fixed integration period (that is, a fixed frequency) is often used to measure the measurand. If the integration period is shorter, although the measured value obtained by integration is closer to the real value, it will cause a problem of high power consumption; The integration period is long, although it...
