Description
Technical Field
The invention relates to the technical field of gas meters, in particular to an energy-saving gas meter and an implementation method and system thereof.
Background
Since the 21 st century, the development of various energy development and application is more and more advanced, and the development of gas energy supply and use in China is remarkable, and although the starting is late, the development is greatly increased in recent years. The gas is of various types, mainly including natural gas, artificial gas, liquefied petroleum gas, biogas and coal gas, taking natural gas as an example: compared with gasoline and diesel oil, the price of the energy-saving diesel oil is 30% -50% lower, the energy-saving diesel oil has obvious economy, and simultaneously, as the country increasingly pays more attention to environmental protection and the market continuously increases the requirement on clean energy, the energy-saving diesel oil is used as clean, efficient and cheap energy, and the consumption is rapidly developed. In contrast, the development and construction of the urban gas supply system are very rapid, and the gas meter is used as a metering and controlling device for gas used by a gas user, so that the installation and application quantity is very large.
At present, a gas meter installed at a user side mainly has the functions of automatic metering, remote gas data sending, remote cut-off of a built-in valve, interruption of gas supply and the like. The system is mainly powered by a battery, and the working state of the system can be simply summarized into four modes: shutdown mode, power saving mode, metering mode, and special mode. The shutdown mode refers to that the power supply is disconnected, the gas meter cannot work normally, the gas cannot be conveyed and measured, and the battery is in a natural discharge process. The energy-saving mode means that the CPU, the metering module, the communication module, the switch valve circuit and the like are in a sleep state, the gas meter cannot receive communication signals, and the system operation is maintained at the lowest power consumption. The working mode refers to that a metering gauge in the gas meter rotates, and meanwhile, the CPU and the metering module are awakened to carry out electronic metering and store metering data. The special mode is that a built-in program sets a timer/timer clock to count to a preset time (generally 0 point in the morning), and a communication module is automatically started to receive a related notification signal of the gas remote control center, wherein the signal is a valve closing instruction sent by a background when the gas remote control center finds that a user has serious gas utilization hidden trouble, and the valve closing instruction is used for ensuring the life and property safety of the user. And if the gas meter receives a valve closing instruction, starting a switch valve circuit to close the built-in valve of the meter, and closing the gas.
In view of the serious danger of methane and carbon monoxide in the gas, if the gas meter automatically starts the working mode of the communication module according to the preset time (generally 0 point in the morning), the communication has obvious hysteresis. Especially, in the process that a user is using gas, if the gas meter cannot receive a valve closing instruction sent by the background of the gas remote control center as soon as possible, the possibility of safety accidents is high. In contrast, when a communication module in the existing gas meter works, the energy consumption in the gas meter is more than three times that in a metering mode and far exceeds that in an energy-saving mode, so that if the communication module is always started to keep communication connection with a gas remote control center, the working time limit of the gas meter is greatly shortened, a battery needs to be replaced very frequently, and a large amount of electric energy is wasted. In the prior art, no good technical scheme is available for effectively solving the two problems of reducing the safety risk and saving energy.

The embodiment of the invention provides a structural framework of a gas meter, which can reduce the safety risk of household gas of a user, and meanwhile, the gas meter has an energy-saving effect and can continuously work for a long time. The following description is made of a gas meter according to an embodiment of the present invention with reference to fig. 1:
in the embodiment of the present invention, the collection module 101 is configured to detect the usage of the gas and measure the usage of the gas when the gas is used, and a measurement meter commonly used in an existing smart gas meter may be used as a related measurement device in the collection module 101, and the measurement meter may also be generally referred to as a base meter. Specifically, some alternative metrology instrument implementations and principles include, but are not limited to, the following: 1. the turbine flowmeter is characterized in that a turbine is arranged in the center of a gas pipeline, and a rectifier is installed in front of the turbine. When the gas is used, the gas impacts turbine blades in the process of passing through a pipeline to generate driving torque on the turbine, so that the turbine overcomes friction torque and fluid resistance torque to rotate, and the rotation angular speed of the turbine is in direct proportion to the flow speed of fluid in a certain flow range for a certain gas medium. Therefore, the use condition of the gas can be conveniently acquired according to the detected gas flow condition, and the gas can be further acquired through measurement in a mechanical transmission mode, a magnetic coupling mode and the like according to the rotation angular velocity of the turbine, and specifically, when the blades of the turbine flowmeter cut magnetic lines generated by permanent magnet steel in the shell, the magnetic flux change in the sensing coil can be caused. The sensing coil sends the detected magnetic flux periodic variation signal to a preamplifier, amplifies and shapes the signal, generates a pulse signal in direct proportion to the flow velocity, and sends the pulse signal to a unit conversion and flow integrating circuit to obtain an accumulated flow value; meanwhile, the pulse signal is sent to the frequency current conversion circuit, the pulse signal is converted into analog current, an instantaneous working condition flow value is indicated, and the accumulated flow value and the working condition flow value are transmitted to the acquisition module 101 for storage and recording in real time. 2. A Roots flowmeter, a positive displacement flow meter, in which when a gas passes through the Roots flowmeter, a differential pressure generated between an inlet and an outlet acts on a pair of Roots wheels coupled to a high-precision synchronizing gear, thereby driving the Roots wheels to rotate. During this period, the metering chamber, which is the sealed space formed between the Roots wheel and the inner wall of the housing and the gland, is periodically inflated and deflated. The number of roots wheel revolutions is proportional to the volume of gas passing through the roots meter. The rotation of the Roots wheel is transmitted to the mechanical counter (or output flow pulse signals) through the magnetic coupler, so that the volume flowing through the metering cavity is accumulated to achieve the purpose of metering, and the specific magnetic coupling measurement metering principle and the acquired data are similar to those of the turbine flowmeter and are not repeated.
The switching valve module 102 in the gas meter mainly aims at the safety requirement of emergency cut-off of gas source on the medium-low pressure pipeline (namely, the user side) of urban gas. Certainly, compared with the conventional diaphragm gas meter, the prepayment function of "first payment and second consumption" which can be realized by the intelligent gas meter is also realized based on the switch valve and the related control module 105, and in the embodiment of the invention, the switch valve module 102 is mainly controlled based on the safety requirement.

The timer module 103 is controlled by the control module 105 to perform timing, and the timer module 103 may be set as a hardware timer according to specific precision requirements, or may adopt a simulated software timer to meet timing application requirements. The control module 105 is configured to control the working states of the switching valve module 102, the timer module 103, and the communication module 104, and specifically includes: in addition to the turn-off operation of the on-off valve module 102, the timing of the timer module 103, the communication connection and information transmission and reception of the communication module 104, the control module 105 also controls the on-off valve module 102, the timer module 103 and the communication module 104 to enter a working mode or a sleep mode.

Referring to fig. 3, the following detailed description is made of an operation logic flow of the energy-saving gas meter according to an embodiment of the present invention, where the operation logic flow is specifically as follows:
step S101: the acquisition module detects that a user starts to use the fuel gas, and executes the step S102 and the step S103;
step S102: the metering gauge in the acquisition module starts to meter the usage amount of the fuel gas;
step S103: the acquisition module sends a fourth interrupt request signal to the control module, the control module is awakened to enter a working mode after receiving the fourth interrupt request signal, and step S104 is executed;
step S104: the control module sends a second interrupt request signal to the timer module, the timer module is awakened to enter a working mode after receiving the second interrupt request signal, starts to time the service time of the gas, and executes the step S105;
step S105: judging whether the timing time of the timer module reaches a first time threshold value, if so, executing a step S106, otherwise, executing a step S113;
step S106: the control module sends a first interrupt request signal to the communication module, the communication module is awakened to enter a working mode after receiving the first interrupt request signal, starts to receive and/or acquire instruction information (the instruction information is used for informing the control module to control the switching valve module to act so as to realize gas shutoff), and step S107 is executed;
step S107: judging whether the communication module receives or acquires the instruction information, if so, sending the instruction information to the control module, and executing the step S108, otherwise, executing the step S111;
step S108: the control module sends a third interrupt request signal to the switch valve module, and the switch valve module is awakened to act after receiving the third interrupt request signal, so that gas shutoff is realized, and step S109 is executed;
step S109: the gas is turned off, the acquisition module finishes metering, and step S110 is executed;
step S110: the control module sends a first sleep signal to the switch valve module and the communication module, the switch valve module and the communication module enter a sleep mode after receiving the first sleep signal, and step S112 is executed;
step S111: the control module sends a first sleep signal to the communication module, the communication module enters a sleep mode after receiving the first sleep signal, and step S112 is executed;
step S112: the control module sends a reset signal to the timer module, and the timer module clears the timing time after receiving the reset signal;
step S113: judging whether the timer module receives the first sleep signal, if so, executing step S114, otherwise, executing step S105;
step S114: the timer module enters the sleep mode, performs step S115,
step S115: the acquisition module sends a second sleep signal to the control module, and the control module enters a sleep mode after receiving the second sleep signal.
It should be added that, in the above flow, the user may stop using the gas at any time, at this time, the control module will send the first sleep signal to the timer module, and the gas meter will sequentially execute step S109, step S112, step S113, step S114, and step 115.
The logic and the principle of a specific application example of the energy-saving gas meter according to the embodiment of the present invention are explained with reference to the above operation logic, wherein the first time threshold is set to 10 minutes.
Specific application example 1: if the time period for the user to use the gas is 5 minutes, the gas meter provided by the embodiment of the invention firstly executes the step S101 and the step S102, the detection module detects the situation after the user starts to use the gas, and the metering meter in the gas meter is started to meter the usage amount of the gas. Meanwhile, the acquisition module also wakes up the control module, and the control module further wakes up the timer module to start timing the service time of the fuel gas, and the process is very short, so that the metering of the metering gauge and the timing of the timer module can be roughly considered to be synchronous. In the process of timing by the timer, the control module compares the timing time with the preset 10 minutes in real time, if the time does not reach 10 minutes and the user does not stop using the gas, the judgment results of the step S105 and the step S113 are negative, at this time, the step S104 is returned, and the timer is still in the working state, so that the step of waking up can be omitted, and the gas use time is continuously timed. In this specific application example 1, the user stops using the gas after 5 minutes, so that the determination result of step S113 is yes after 5 minutes, and the gas meter enters the energy saving state (i.e., the control module, the timer module, the communication module, and the switch valve module all enter the sleep mode state) after steps S114 and S115 are executed.
In the specific application example 2, the time for the user to use the gas is 15 minutes, and during or before the time, the gas remote control center does not find potential safety hazards and does not send instruction information for closing the valve. In this example, unlike application example 1, when the gas usage time of the user reaches the 10 th minute, the determination result in step S105 is yes, and therefore, step S106 and step S107 are continuously executed. In step S107, since the remote gas control center does not find any potential safety hazard during or before this period, and does not send the instruction information for closing the valve, if the determination result is no, the gas meter will continue to execute step S111 and step S112, the communication module enters the sleep mode, and the counted time of the current timer is cleared. The subsequent 5 minutes of gas usage by the user is similar to the above specific application example 1 and will not be described again here.
In a specific application example 3, the gas using time of the user is 15 minutes, and during or before the time, the gas remote control center finds potential safety hazards and sends command information of closing the valve. In this example, different from the specific application example 2, when the step S107 is executed, since the gas remote control center finds a potential safety hazard during or before the period, and sends the instruction information for closing the valve, the gas meter will continue to execute the steps S108, S109, S110, and S112 as a result of the determination, that is, the control module controls the switching valve module to execute the valve closing operation, so as to eliminate the risk of the potential safety hazard, and ensure the personal safety and property safety of the user, and then the gas will automatically stop inputting at this time due to the turn-off of the gas valve, and the control module will send the first sleep signal to the timer module. In a specific application operation, the user can be informed of the reason for the shutdown and the existing security risk at this time. Meanwhile, the subsequent step of the gas meter entering the energy-saving state (i.e., the state that the control module, the timer module, the communication module and the switch valve module all enter the sleep mode) is similar to that of the specific application examples 1 and 2, and is not described herein.
The following can be known from the above operation logic flow and specific application example: the energy-saving gas meter provided by the embodiment of the invention can effectively and timely establish communication connection with a gas remote control center in the process of using gas by a user, and timely acquire potential safety hazard information and corresponding control indication information which may exist in the process of using gas by the user, so that the safety of using gas by the user and the timeliness of information notification are guaranteed. Meanwhile, each module in the gas meter can be used as best as possible, and the gas meter can quickly enter a sleep mode after entering a working mode for completing required work, so that the consumption of electric energy is greatly saved, and the reliability and the durability of the use of the gas meter are ensured. In addition, it should be understood that, in a practical application, the setting of the first time threshold is very flexible, and may be set according to practical considerations of actual gas usage, safety and energy saving, and the above specific application example does not represent a fixed limitation on the value thereof.
Referring to fig. 4, an embodiment of the present invention provides a gas meter control method, which is used for controlling the gas meter, and includes the following steps:
s1: timing the use time of the fuel gas to obtain timing time;
s2: when the timing time reaches a preset first time threshold, waking up the communication module in a sleep mode;
s3: when the communication module receives instruction information, the switching valve module of the gas meter is controlled to act to realize gas shutoff, and the instruction information is control notification information sent by a remote control center.
Further, as a preferred implementation, an embodiment of the present invention provides another gas meter control method, configured to control the gas meter, including the following steps:
s4: timing the use time of the fuel gas to obtain timing time;
s5: when the timing time reaches a preset first time threshold, waking up the communication module in a sleep mode;
s6: when the communication module obtains instruction information, the switching valve module of the gas meter is controlled to act to realize gas shutoff, and the instruction information is control notification information stored in a remote control center.
Two gas meter control method embodiments in the embodiments of the present invention are provided based on the energy-saving gas meter, and are used for controlling the energy-saving gas meter to realize specific functions thereof, and the specific difference of the two gas meter control method embodiments is only in step S3 and step S6, which are two specific limitations on the communication connection manner of the communication module and the remote control center, respectively, and when the communication module enters a working mode, the communication module can be used to receive instruction information sent by the remote control center, and can also be set to be a manner of actively acquiring the instruction information.
