Description
Technical Field
The invention relates to the technical field of gas metering, in particular to a gas meter metering method and system.
Background
At present, natural gas is widely applied as clean new energy, and almost all households use the natural gas. The diaphragm gas meter is used as a measuring appliance by a natural gas method, and becomes one of the most common household three meters together with a water meter and an electric meter.
The diaphragm gas meter has about 200 years of application history today, and the working principle of the diaphragm gas meter is mainly that gas pushes a diaphragm in a cavity to move so as to drive a mechanical gear to rotate, so that the volume of the gas is measured. The stability and reliability of the device are outstanding, and the fluid metering can be completed only through mechanical transmission without depending on external energy (power supply). In order to improve the meter reading efficiency and reduce the cost caused by manual meter reading, an external main control unit is additionally arranged on a plurality of membrane type gas meters at present, and the functions of remote communication, prepayment, valve control and the like are realized.
In order to realize the above function, the most important task is to read out and process the accumulated gas amount of the base table portion. The most common mode in the market at present is to indirectly calculate the cumulant by reading the pulse number through a reed switch, or directly read the cumulant through a photoelectric direct reading module.
However, both reed switch reading and photoelectric direct reading have poor data real-time performance. The data real-time performance is very poor when the photoelectric direct-reading sampling is carried out for one time in 1 hour, at least dozens of seconds are needed when the reed switch runs out of one sampling period in a household environment, and the real-time performance is very common. When the real-time performance of the data is poor, the problem of safe gas utilization is highlighted. For example, when a pipe section connected to a gas meter is dropped or damaged, natural gas leakage occurs, and if real-time flow cannot be monitored in a short time, a major safety accident is likely to be caused.

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.
An embodiment of the present invention provides a diaphragm gas meter, as shown in fig. 1, including: the first Hall switch U5, the second Hall switch U2, the third Hall switch U3, the fourth Hall switch U4 and install the permanent magnet on the gear, first Hall switch U5, second Hall switch U2, third Hall switch U3, fourth Hall switch U4 are along gear circumference evenly distributed.
In a specific embodiment, as shown in fig. 1, the diaphragm gas meter further includes a single chip microcomputer U1, and the first hall switch U5, the second hall switch U2, the third hall switch U3, and the fourth hall switch U4 are all connected to the single chip microcomputer U1, and are configured to send a generated pulse signal to the single chip microcomputer U1 in an enable state. And then the singlechip U1 calculates according to the two pulse signals to obtain the gas flow. Specifically, the gear rotates to drive the permanent magnet to rotate, and when the permanent magnet passes through the hall switch, the magnetic field of the environment where the hall switch is located changes. Due to the Hall effect, the Hall sensor generates Hall potential with corresponding magnitude, so that a pulse signal is generated and sent to the single chip microcomputer, the single chip microcomputer can obtain the gas volume according to the pulse number, and real-time flow can be obtained according to the time interval between two pulses.
In the embodiment of the invention, the Hall switch has the characteristics of low cost and good stability compared with a reed switch. Even if 4 groups of Hall switches are adopted, the cost is lower than that of a single reed switch and an optoelectronic direct-reading module.
The embodiment of the invention also provides a gas meter metering method, which is applied to the diaphragm gas meter, and as shown in fig. 2, the gas meter metering method comprises the following steps:
step S1: and recording the full-period sampling time of the diaphragm gas meter in a conventional sampling mode.
In a specific embodiment, the full-period sampling time of the membrane gas meter in the conventional sampling mode is recorded by the following steps:
step S11: enabling the first Hall switch U5, and recording the starting time of the first Hall switch U5 for generating a pulse signal when the permanent magnet passes through the first Hall switch U5 for the first time;
step S12: when the permanent magnet passes through the first Hall switch U5 for the second time, recording the termination time of the pulse signal generated by the first Hall switch U5;
step S13: and performing difference calculation on the starting time and the ending time to obtain the full-period sampling time in the conventional sampling mode.
In the embodiment of the invention, the first Hall switch U5 is enabled, and the diaphragm gas meter enters a conventional sampling mode to perform full-period sampling. In the gear rotating process, the gear can simultaneously drive the permanent magnet to rotate when rotating, and when the permanent magnet passes through the first Hall switch U5 for the first time, the singlechip U1 records time t1 when acquiring a first pulse signal; when the permanent magnet passes through the first Hall switch U5 for the second time, the singlechip U1 records time t2 when acquiring the second pulse signal. And calculating the time interval delta T1 between the current sampling and the last sampling, which is T2-T1. At this time, Δ T1 is the full cycle sampling time.
Step S2: and adjusting the sampling mode according to the relation between the full-period sampling time and the preset sampling period threshold value.
In one embodiment, the method for adjusting the sampling mode according to the relationship between the full-period sampling time and the preset sampling period threshold comprises the following steps:
step S21: and when the full-period sampling time is less than the preset sampling period threshold value, adjusting the conventional sampling mode into a fast sampling mode.
Step S22: and when the full-period sampling time is not less than the preset sampling period threshold value, keeping the normal sampling mode.
In the embodiment of the present invention, a preset sampling period threshold T is defined for determining whether to enter the fast sampling mode. For example at 1m3The flow rate is taken as the corresponding flow rate in the process of rapid sampling, the gear rotates for one circle, and the precision is 0.01m3Then rotate a circle by 0.01m3The required time is 0.01/1-0.01 h 3600 s-36 s, and the 36 seconds are used as a preset sampling period threshold.
Further, the setting of the preset sampling period threshold T needs to be fitted to an actual application scene. For example, in a scene with small gas consumption, the threshold flow can be set to be smaller, so that T becomes larger; in a scenario where the gas usage is large, the threshold flow rate may be set large, and T may be set small.
Further, if Δ T1 is smaller than the preset sampling period threshold T, the fast sampling mode is entered, otherwise the normal sampling mode is continued.
Step S3: and calculating the real-time gas flow in the adjusted sampling mode.
In a specific embodiment, calculating the real-time gas flow in the adjusted sampling mode includes two ways: and calculating the real-time gas flow in a rapid sampling mode or calculating the real-time gas flow in a conventional sampling mode.
In the embodiment of the invention, the calculation of the real-time gas flow in the fast sampling mode comprises the following steps:
step S311: the first hall switch U5, the second hall switch U2, the third hall switch U3, and the fourth hall switch U4 are enabled.
Step S312: when the permanent magnet passes through the first hall switch U5, the second hall switch U2, the third hall switch U3 and the fourth hall switch U4, the first time when the first hall switch U5 generates the pulse signal, the second time when the second hall switch U2 generates the pulse signal, the third time when the third hall switch U3 generates the pulse signal and the fourth time when the fourth hall switch U4 generates the pulse signal are recorded respectively.
Step S313: and respectively calculating a first time difference between the second time and the first time, a second time difference between the third time and the second time, and a third time difference between the fourth time and the third time.
Step S314: and calculating the gas flow in real time according to the first time difference, the second time difference, the third time difference and the precision of the diaphragm gas meter.
Specifically, if the fast sampling mode is entered, the three hall switches U2, U3, U4 are enabled. In the fast sampling mode, two pulse signals can be generated by one quarter of gear rotation, and the time difference delta T2 of the two pulse signals is recorded. The precision is 0.01m due to one rotation of the gear3Then the actual volume corresponding to one quarter turn of gear rotation is 0.01m3One quarter of (1), i.e. 0.0025m3. Finally, the real-time flow rate V is 0.0025/. DELTA.T 2.
In the embodiment of the invention, the calculation of the real-time gas flow in the conventional sampling mode comprises the following steps:
step S321: the first hall switch U5 is enabled, recording the start time of the pulse signal generated by the first hall switch U5 when the permanent magnet passes the first hall switch U5 for the first time.
Step S322: the end time of the pulse signal generated by the first hall switch U5 is recorded when the permanent magnet passes the first hall switch U5 a second time.
Step S323: performing difference calculation on the starting time and the ending time to obtain a fourth time difference;
step S324: and calculating the gas flow according to the fourth time difference and the precision of the diaphragm gas meter.
Specifically, if the normal sampling mode is entered, the first hall switch U5 is enabled. In the normal sampling mode, two pulse signals are generated by one complete rotation of the gear, and the time difference Delta T1 of the two pulse signals is recorded. The precision is 0.01m due to one rotation of the gear3The actual volume corresponding to a complete revolution of the gear is then 0.01m3. Finally, the real-time flow rate V is 0.01/. DELTA.T 1.
In the embodiment of the invention, two different sampling modes, namely a conventional sampling mode and a quick sampling mode, are established through reasonable linkage of the four Hall switches. And reasonably switching between the two sampling modes according to the relation between the current full-period sampling time and a preset sampling period threshold value. When the sampling circuit is in a conventional sampling mode, the real-time requirement of data is low, and the requirement can be met only through the action of one Hall switch, so that the power consumption is reduced; after the rapid sampling mode is entered, the four Hall switches act together, two pulses can be captured by a quarter of a circle, the real-time performance of data is improved by 4 times, and the real-time flow with high precision and high real-time performance can be obtained.
Furthermore, according to the real-time flow with high precision and high real-time property acquired in the rapid sampling mode, various alarm functions and valve control functions can be linked. If abnormal real-time flow occurs, such as overload flow, leakage flow (relatively constant medium-high flow) and the like, the abnormal real-time flow can be identified in a short time, and alarm and valve closing operations can be carried out, so that the safety performance of the diaphragm gas meter is greatly improved, and the safe gas use of a user is ensured.
