The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.

In addition, the technical features involved in the different embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

The embodiment of the invention provides a gas meter matching method, as shown in fig. 1, comprising the following steps:

step S10: and acquiring the gas flow used by the target user.

In one embodiment, the gas flow is typically obtained by a metering unit of the gas meter itself. The method comprises the following specific steps:

step S101: acquiring a first pulse signal triggered by a first Hall switch and a second pulse signal triggered by a second Hall switch in a current gas meter of a target user;

step S102: and calculating the gas flow passing through the gas meter according to the time difference between the first pulse signal and the second pulse signal.

In the embodiment of the invention, as shown in fig. 2, the metering unit of the gas meter itself is composed of a gear S1, a magnet S2, a first hall switch U2, a second hall switch U3 and a main control unit U1 which is composed of a single chip microcomputer. When the gas meter is in the ventilation process, the gear S1 drives the magnet S2 to do circular motion (10 liters in one circle), the magnet S2 is sequentially close to the first Hall switch U2 and the second Hall switch U3 in the rotation process, so that pulse signals (HALF and WHOLE) are respectively triggered to the single chip microcomputer, and the single chip microcomputer calculates the gas flow passing through the gas meter according to the time difference of 2 pulses.

Step S20: and analyzing the air consumption ratio of the target user in different flow areas according to the gas flow.

In a specific embodiment, analyzing the gas consumption ratio of the target user in different flow areas according to the gas flow specifically comprises the following steps:

step S201: setting a first flow threshold and a second flow threshold corresponding to the current gas meter of the target user according to the phenotype of the current gas meter of the target user, wherein the first flow threshold is larger than the second flow threshold;

step S202: setting a gas flow analysis and statistics period according to the target statistics period;

step S203: and calculating a first flow ratio, a normal flow ratio and a second flow ratio according to the gas flow exceeding the first flow threshold accumulated amount, the gas flow lower than the second flow threshold accumulated amount and the cycle total amount.

In the embodiment of the invention, 5 parameters are stored in a single chip microcomputer: large flow threshold, accumulated amount above large flow threshold, small flow threshold, accumulated amount below small flow threshold, calculation period, and total period usage. The first flow threshold is a large flow threshold, and the second flow threshold is a small flow threshold. The accumulated gas usage amount exceeding the large flow threshold value exceeds the first flow threshold value, and the accumulated gas usage amount below the small flow threshold value is lower than the second flow threshold value. The total consumption of the cycle is the accumulated amount of the gas in one calculation cycle.

The second flow rate is a ratio of the accumulated amount of air below the second flow rate threshold to the accumulated amount of air in a calculation cycle. The first flow rate is a ratio of the accumulated air amount exceeding the first flow rate threshold to the accumulated air amount in one calculation cycle. The normal flow rate is the proportion of the accumulated air quantity between the large flow rate threshold value and the small flow rate threshold value in a calculation period.

Specifically, different large flow thresholds and small flow thresholds are set according to different phenotypes. Different calculation periods are set according to the requirement of the statistical period. And then the single chip microcomputer calculates the ratio of the ultra-small flow, the normal flow and the ultra-large flow according to the accumulated quantity exceeding the large flow threshold, the accumulated quantity below the small flow threshold and the total periodic consumption, so as to analyze whether the table is adaptive or not.

Step S30: and selecting and matching corresponding gas meters according to the gas consumption ratios of the users in different flow areas.

In a specific embodiment, the method for selecting and allocating the corresponding gas meters according to the gas consumption of the user in different flow areas specifically comprises the following steps:

step S301: and selecting and matching corresponding gas meters according to the first flow ratio, the normal flow ratio and the second flow ratio.

In the embodiment of the present invention, selecting and matching corresponding gas meters according to the first flow rate ratio, the normal flow rate ratio, and the second flow rate ratio specifically includes the following steps:

step S3011: when the first flow rate ratio is larger than the normal flow rate ratio, adjusting the current gas meter into a gas meter with the precision larger than the preset multiple precision of the current gas meter;

and S3012, when the second flow rate is greater than the normal flow rate, adjusting the current gas meter to a gas meter with the precision smaller than the precision of the current gas meter by a preset multiple.

Specifically, when the first flow rate ratio is larger than the normal flow rate ratio or the second flow rate ratio is larger than the normal flow rate ratio, the metering error is in a negative error. This is unfair to both the consumer and the gas company, so it is necessary to reasonably analyze the range in which the consumer's gas flow is located. And when the first flow rate ratio is larger than the normal flow rate ratio, the current gas meter is considered to be undersize, and the current gas meter is adjusted to be the gas meter with the precision larger than the preset multiple precision. And when the second flow rate is larger than the normal flow rate, the current gas meter is considered to be overlarge, and the current gas meter is adjusted to be the gas meter with the precision smaller than the precision of the current gas meter by a preset multiple. In the embodiment of the invention, the preset times are determined according to the gas meter phenotype.

In one embodiment, as shown in fig. 3, zone a is below a low flow threshold, zone B is a normal flow threshold, and zone C is above a high flow threshold. When the gas consumption of the user is always in the area A or the area C, the metering error is in a negative error. And when the error is in the B area, the metering error is in a positive error. This is unfair to both the consumer and the gas company, so it is necessary to reasonably analyze the range in which the consumer's gas flow is located.

Therefore, the concepts of a low flow area and a high flow area are introduced, the accumulated use amount of ABC3 areas is respectively calculated by calculating the real-time flow of the gas meter, when the area C is far larger than the area B, the current distribution meter is considered to be too small, and the current gas meter is adjusted to be a gas meter which is one-meter larger than the current gas meter; when the area A is far larger than the area B, the current gas meter is considered to be too large, and the current gas meter is adjusted to be a gas meter which is smaller than the current gas meter by one meter.
