[0039] The specific embodiments of the present disclosure have been shown through the above-described drawings, and will be described in more detail hereinafter. These drawings and the written description are not intended to restrict the scope of the concept of the present disclosure by any means, but to illustrate the concept of the present disclosure to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0040] The exemplary embodiments will be described in detail herein with reference to the attached drawings. In the following description, the same numbers are used to indicate the same or similar components. The embodiments described in the following exemplary embodiments do not represent all the embodiments consistent with the present disclosure. Rather, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0041] The intelligent gas meter is a new type of gas meter that automatically completes meter reading, charging, report generation and other businesses through an intelligent system. With the rapid development of the gas metering industry, intelligent gas meters are increasingly widely used.

[0042] In the conventional intelligent gas meter, a fixed metering time is set for monitoring the gas flow in the gas and whether the gas leaks or not. This is beneficial to metering at a small flow rate, but when the flow rate changes rapidly, the fixed-time metering method has the problem of not responding in time. The gas flow monitoring is not timely enough, and the displayed flow rate is updated slowly, which may cause the user and the gas management center to be unable to grasp the gas state in time, thereby causing the problem of poor gas flow monitoring effect. In addition, when the gas volume changes rapidly, only obtaining a preset number of gas flow rates may cause the problem of insufficient accuracy of the displayed gas flow rate.

[0043] Therefore, the traditional intelligent gas meter has the problems of slow calculation speed and poor monitoring effect when monitoring the gas flow and gas leakage in the gas.

[0044] Based on this, the application provides a gas flow monitoring method, which obtains less gas flow to calculate the indicated gas flow when the gas volume changes slowly. In this way, the update speed of the indicated gas flow is improved. Moreover, more gas flow is obtained to calculate the indicated gas flow when the gas volume changes faster, so as to improve the calculation accuracy of the indicated gas flow, and make the indicated gas flow more objectively reflect the gas volume change state.

[0045] The gas flow monitoring method provided by the application is applied to an electronic device, such as an intelligent gas meter or other electronic device for monitoring gas changes. Figure 1 For the application of the gas flow monitoring method provided by the application, the electronic device monitors the gas changes and records a change time when the gas volume reaches Vc. Then, the period gas flow corresponding to the time (the average change value of the gas volume in the time period from the last time to the current time) is determined according to the recorded change time. Then, the number of period gas flows used in the calculation of the indicated gas flow is determined based on the period gas flow and the period gas flow range, and the value N of the period gas flow is determined to calculate the indicated gas flow at this time. Finally, the indicated gas flow at this time is calculated by taking the corresponding indicated gas flow.

[0046] Please refer to Figure 2 One of the embodiments of the application provides a gas flow monitoring method, comprising:

[0047] S210, record adjacent first change time and second change time, the first change time and the second change time are the time when the gas volume reaches the preset volume.

[0048] A change time is recorded each time the gas volume changes by a preset volume. After the electronic device is started, the first time the gas volume changes by the preset volume, the time t1 is recorded, and the second time the gas volume changes by the preset volume, the time t2 is recorded, and so on. The first change time and the second change time are adjacent change times, the first change time is t i , the second change time is t i+1 , and i represents the i-th recorded change time.

[0049] Optionally, in order to ensure the smoothness of the operation, only a preset number of change moments can be recorded, and the number of change moments corresponding to the latest n times (n is equal to the preset number) of volume changes reaching the preset volume is always maintained as the preset number. When the number of recorded change moments is greater than the preset number, the earliest M change moments can be erased from the recorded multiple change moments, so that the number of recorded change moments is less than or equal to the preset number, and M is an integer greater than zero. For example, the preset number is 10, that is, only 10 change moments t1 to t 10 When the 11th change moment is to be recorded, the earliest recorded change moment or moments are erased from the recorded 10 change moments. For example, t1 is erased from t1 to t 10 , or t1 and t2 are erased from t1 to t 10 .

[0050] When the number of recorded change moments is greater than the preset number, the time of erasing the earliest M change moments from the recorded multiple change moments can be when a new change moment is to be recorded, or at any time, or after a new change moment has been recorded. When recording the second change moment, the first thing to ensure is that the second change moment is recorded, and the second change moment cannot be recorded because the number of recorded change moments is greater than the preset number.

[0051] S220, determining the periodic gas flow corresponding to the second change moment according to the first change moment, the second change moment, and the preset volume.

[0052] Optionally, the periodic gas flow corresponding to the second change moment is calculated according to the first change moment and the second change moment, and then the value obtained by dividing the preset volume by the gas change duration is the periodic gas flow corresponding to the second change moment. For example, the first change moment is t i , the second change moment is t i+1 , and the preset volume is Vc, then the periodic gas flow Q i = Vc / (t i+1 -t i ).

[0053] S230, obtaining the number N of periodic gas flows used when calculating the apparent gas flow of the second change moment according to the periodic gas flow corresponding to the second change moment and the number of periodic gas flows used when calculating the apparent gas flow according to the preset periodic gas flow range, N is an integer greater than zero; the larger the periodic gas flow range, the larger the number of periodic gas flows used when calculating the gas apparent flow.

[0054] Optionally, the number of periodic gas flow used in calculating the displayed gas flow in each preset periodic gas flow range can be stored in the electronic device in the form of a storage table. As shown in Table 1, assuming the periodic gas flow Q 10 = 0.9, the corresponding K value (the number of periodic gas flow used in calculating the displayed gas flow) is equal to 3.

[0055] Table 1:

[0056]

[0057] In order to make the calculation of the displayed gas flow faster, the larger the periodic gas flow, the larger the number of periodic gas flow used in calculating the displayed gas flow, and the smaller the periodic gas flow, the smaller the number of periodic gas flow used in calculating the displayed gas flow. That is, when the gas volume changes more slowly, only one or two recent change times before the second change time can be used to calculate the displayed gas flow at the second change time, which can improve the calculation speed of the displayed gas flow when the gas volume changes slowly. When the gas volume changes quickly, seven or nine recent change times before the second change time are obtained to calculate the displayed gas flow at the second change time, which can improve the calculation accuracy and precision of the displayed gas flow when the gas volume changes quickly, so that the calculated displayed gas flow can more truly reflect the gas change.

[0058] S240, obtaining the periodic gas flow corresponding to the N-1 change times before the second change time, and determining the displayed gas flow at the second change time according to the periodic gas flow corresponding to the N-1 change times and the periodic gas flow corresponding to the second change time.

[0059] As described in step S230, for example, the periodic gas flow Q 10 = 0.9, the corresponding K value (the number of periodic gas flow used in calculating the displayed gas flow) is equal to 3, and the displayed gas flow Q at the second change time is Q = (Q 10 + Q9+ Q8) / 3.

[0060] As described in step S210, a change time is recorded each time the gas volume changes by a preset volume. Optionally, if the number of recorded change times is greater than or equal to N by the second change time, the periodic gas flow corresponding to the N-1 change times before the second change time can be obtained, and the displayed gas flow at the second change time can be determined according to the periodic gas flow corresponding to the N-1 change times and the periodic gas flow corresponding to the second change time.

[0061] For example, as shown in Table 1, when Q = 0.9, the corresponding calculated value number K of the apparent gas flow is 3, and at this time, 10 change moments have been recorded, so the apparent gas flow corresponding to Q8 to Q 10 10 respectively, and the corresponding calculated value number K of the apparent gas flow is 7. At this time, only 5 change moments have been recorded, and there are only 4 change moments before Q5, so the apparent gas flow corresponding to Q5 is calculated according to the periodic gas flow corresponding to Q1 to Q5 respectively. At this time, Q = (Q5 + Q4 + Q3 + Q2 + Q1) / 5. 10 10 respectively, and the corresponding calculated value number K of the apparent gas flow is 7. At this time, only 5 change moments have been recorded, and there are only 4 change moments before Q5, so the apparent gas flow corresponding to Q5 is calculated according to the periodic gas flow corresponding to Q1 to Q5 respectively. At this time, Q = (Q5 + Q4 + Q3 + Q2 + Q1) / 5.

[0062] For example, as shown in Table 1, when Q = 0.9, the corresponding calculated value number K of the apparent gas flow is 3, and at this time, 10 change moments have been recorded, so the apparent gas flow corresponding to Q8 to Q

[0063] For example, as shown in Table 1, when Q = 0.9, the corresponding calculated value number K of the apparent gas flow is 3, and at this time, 10 change moments have been recorded, so the apparent gas flow corresponding to Q8 to Q

[0064] In addition, as described in step S210, in order to ensure the smoothness of the operation, only a preset number of change moments can be recorded, and the number of change moments corresponding to the last n times (n is equal to the preset number) of volume changes reaching the preset volume is always maintained to be the preset number. Alternatively, in the corresponding relationship between the periodic gas flow and the calculated value number of the apparent gas flow, the calculated value number of the apparent gas flow should be less than the preset number. For example, if the electronic device only records the last 10 change moments, then in the corresponding relationship between the periodic gas flow and the calculated value number of the apparent gas flow, the maximum value of the calculated value number (K) of the apparent gas flow is 9.

[0065] Alternatively, when the apparent gas flow corresponding to the second change moment is less than or equal to the warning flow value, an alarm signal can be sent out, which can be an audible alarm signal. If, for example, a gas leak is found or a valve is forgotten to be closed during gas use, the apparent gas flow will become smaller, so when the apparent gas flow is less than or equal to the warning flow value, an alarm signal can be sent out to remind the user to pay attention to gas safety. Compared with the traditional alarm method of the intelligent gas meter, the method provided in the embodiment has a faster monitoring speed and more accurate results when monitoring the volume change of the gas, so it can improve the accuracy and timeliness of the alarm to ensure gas safety.​​

[0066] In summary, the method provided by the embodiment obtains less gas flow when the gas volume changes slowly to calculate the indicated gas flow. In this way, the updating speed of the indicated gas flow is improved. Moreover, more gas flow is obtained when the gas volume changes faster to calculate the indicated gas flow, so as to improve the calculation accuracy of the indicated gas flow, and make the indicated gas flow more objectively reflect the gas volume change state.
