More particularly, the present invention relates to an electronic gas meter for checking a gas leakage, and more particularly, to an electronic gas meter for checking a gas leak rate, a flow rate and a direction in real time, The present invention relates to an electronic gas meter for gas leakage checking, which enables quick identification and maintenance of a safety accident and a meter trouble.

Generally, gas used for heating or cooking in a home or commercial location is a highly explosive hazardous substance. In particular, the risk of gas leaking in an enclosed space for a long period of time is directly related to the life of a person, so it requires a careful attention to its use.

In most homes, however, there is no special method of shutting off except in the case of the user simply forgetting to turn off the gas-using product or turn off the shut-off valve in the gas-feeding path.

Therefore, the user is exposed to the unprotected state by not turning off the shutoff valve, by damaging the gas used product, by damaging the gas supply path, or by going out while using the gas using product. In addition, the amount of city gas currently used in most households is measured by a method in which a person employed by a city gas supplier visits each household and checks the gas meter.

As a result, the city gas supply company is forced to pay an increase in labor costs due to the hiring of employees and an increase in operating costs due to ineffective work practices.

To solve this problem, a gas meter equipped with an LC resonance sensor has been proposed. Specifically, the volume of the gas passing through the pipe is measured, and the accumulated value is accumulated and divided into a dry type and a wet type.

The dry gas meter utilizes the differential pressure between the inlet and the outlet. There is a diaphragm in the metering chamber. The membrane moves forward and backward by differential pressure on the front and rear sides of the membrane. Actual usage will be displayed.

In addition, the wet gas meter is accurate in weighing and there is almost no fluctuation of the train during use. However, since the water level adjustment is necessary during use, the installation area is wide and expensive, dry gas meter is mainly used in domestic and commercial.

However, the above-mentioned gas meters merely have a function of generating a warning when the flow rate of the gas is changed, but the gas leakage situation is not transmitted to the meter management companies, And the like.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an electronic gas meter for checking gas leakage according to the present invention will be described in detail with reference to the preferred embodiments of the present invention with reference to the accompanying drawings.

FIG. 1 is an enlarged view of an electronic gas meter for checking the gas leakage of the present invention, FIG. 2 is an enlarged view of an enlarged view of the flow measuring gear of FIG. 1, 1 is a block diagram schematically showing a configuration of a gas meter.

1 to 3, an electronic gas meter for checking a gas leakage according to the present invention is provided with an LC resonance element 141 and a flow rate measuring gear 142 to measure a flow of a gas, And notifies the user of the occurrence of a failure. Specifically, the flow rate measuring gear 142 is provided with a second gear 144 coaxially coupled to the rear, and the flow rate measuring gear 142 is connected to the second gear 144 by a power transmitted from the first gear 143, The first gear 142 and the second gear 144 are simultaneously rotated.

The flow rate measuring gear 142 is formed in a disk shape and includes a conductor portion 142a and a non-conductor portion 142b. The axis of the flow rate measuring gear 142 is received in the upper case of the meter body 100, . It is preferable that the conductor portion 142a is formed of a plate member of a fan shape and that the conductor portion 142a is formed of a non-magnetic metal material, and the non-conductor portion 142b It does not matter. Further, although the figure shows that the conductor portion 142a and the non-conductor portion 142b occupy approximately half of each other, it is also possible that one is formed to have a larger size and the other one to have a smaller size.

The flow rate measuring gear 142 is provided with a substrate 145 on its front surface and a display unit (LCD) 110 to be described later is coupled to the substrate 145. The display unit (LCD) 110 includes an LCD window 111 and a speaker 112.

Here, the structure of the electronic gas meter for checking the gas leakage relates to a generally used gas leak check meter, and a detailed description thereof will be omitted.

The flow rate measuring gear 142 includes a meter main body 100 for measuring a rotation amount, a rotation speed and a rotation direction of the flow rate measuring gear 142. The flow rate measuring gear 142 measures the time required for one rotation of the flow rate measuring gear 142, And a display unit (LCD) 110 provided in the meter main body 100 so as to display a converted volume. The display unit (LCD) 110 may include a display unit 111 electrically connected to the board 145 and displaying characters or the like, and a speaker 112 emitting a warning sound. The display unit 110 may be configured by various means including an LCD, and an LCD may be exemplified. For convenience of explanation, the LCD will be described as an example in the present invention.

Alternatively, the flow rate measuring gear 142 may sense the direction of the gas flowing through the pipe and detect the flow of the gas in an abnormal direction so that it can be noticed. For example, when the gas flows in the forward direction, there is no warning, but when the gas flows in the reverse direction, such a situation can be detected and displayed on the LCD 110. In addition, the server 600 transmits such a situation to a later-described server 600, and the server receiving the transmission signal transmits the same to a terminal of the meter managment company or a resident of the resident.

The meter main body 100 and the communication terminal 200 are communicated with each other by a DC-PLC (DC power line communication) and are connected to a watt-hour meter 400 And the communication terminal block 200 are electrically connected to each other.

The communication terminal 200 and the controller 300 transmit the flow rate measurement values transmitted from the communication terminal 200 between the communication terminal 200 and the controller 300 and are connected to the plurality of meter main bodies 100, The dispersion processing unit 500 may further include a dispersion processing unit 500 that receives the flow measurement value transmitted from the main body 100 and distributes the flow measurement value to the control unit 300 and transmits the dispersion measurement result. That is, the flow rate measurement values measured by the plurality of meter main bodies 100 are collected into one unit, and the flow rate measurement values of the respective meter main bodies 100 are transmitted to the respective controllers 300, 300-1, 300-2, It will be a role.

The meter main body 100 and the control unit 300 are configured to wirelessly communicate with each other. When there is an abnormality in the rotation amount, the rotational speed, and the rotational direction of the flow rate measuring gear of the meter main body 100, The control unit 300 transmits the data to the meter main body 100 and the server 600 so that the terminal 700 of the meter managment company can connect to the server 600 wirelessly or by wire. Accordingly, when an abnormal symptom occurs in the main body 100 of the meter, it is detected and transmitted to the control unit 300, and the signal of the abnormal symptom is transmitted to the terminal 700 of the meter reading management company. The terminal 700 may be a PC 710, a laptop computer 720, a smart phone 730, or a tablet PC. The server 600 may be a home network server among various types of servers. Accordingly, when the electronic gas meter for gas leakage check in use in the home is in use, the home network server installed in the room transmits an abnormal symptom to the meter main body 100, and the abnormal symptom is transmitted to the terminal 700 of the meter reading management company . Or to a terminal of an occupant of the residence. That is, the control unit 300 determines that the flow of the gas is abnormal when at least one of the rotation amount, the rotation speed, and the rotation direction of the flow measuring gear 142 is abnormal.

The meter main body 100 is electrically connected to the rechargeable battery 120 so that the main body 100 can be driven by the rechargeable battery 120 when the power is cut off. The meter main body 100 is continuously driven by the rechargeable battery 120 even if the power meter 400 is powered off, that is, a power failure occurs. Therefore, the meter main body 100 is continuously driven by the rechargeable battery 120, The flow rate measurement of the gas can be continuously maintained. In addition, the rechargeable battery 120 is configured so that the remaining power of the rechargeable battery can be displayed through the display unit 111 of the LCD 110. [

The communication terminal 200 may be configured to transmit an abnormal signal to the LCD 110 and the server 600 of the meter body 100 when communication with the meter main body 100 is not smooth. Accordingly, when the electric power is not smoothly supplied to the main body 100 of the meter or the flow of the gas flow rate of the main body 100 is not smoothly detected, it is detected and transmitted to the server 600, .

The meter main body 100 includes a gas leakage detection unit 130 to display a gas leak through the display unit 111 of the LCD 110 or to generate a warning sound through the speaker 112 . ≪ / RTI > Alternatively, it may be configured to send a situation for a gas leak to the server 600. Although it has been described that the detection of the gas leakage is selectively transmitted to the LCD 110 or the server 600, it is possible to display the situation of the gas leakage in addition to the transmission method described above on the LCD 110, 600). ≪ / RTI > Therefore, when the gas is leaked, it is possible to notify such a situation through the terminal to the meter managment company or the resident. Since it is a fact that the gas leakage sensor is used by installing a gas detection sensor (not shown), a detailed description thereof will be omitted.

On the other hand, the meter main body 100 may be configured to recognize that the meter is unused when a certain period of time has elapsed after the gas is not used, and to display it on the LCD 110. For example, when the gas is not used on a closed day or at home in the industrial field, it is displayed on the LCD 110. In addition, since such a situation is possible between the meter main body 100 and the server 600 through wired / wireless communication, it can be implemented to be transmitted to the terminal of the meter managment company or the terminal of the user.

Hereinafter, an operation state of the gas leakage check electronic gas meter of the present invention will be described.

First, the meter main body 100 senses the rotational speed and the rotational direction of the flow measuring gear 142 when using gas in an industrial field or a home. At this time, if the rotation speed is below the minimum speed or above the predetermined speed, the detection signal is transmitted to the controller 300 via the communication terminal 200. The transmitted detection signal is transmitted to the server 600, Or to a resident's terminal. Or between the meter main body 100 and the server 600, this situation is configured to be transmitted to the server 600. That is, when an abnormality occurs in the flow of gas, this abnormal situation is transmitted to the communication terminal 200 or the server 600.

Therefore, according to the gas leakage check electronic gas meter of the present invention configured as described above, when the gas flow is detected in real time and an abnormality occurs, it is detected in real time and informed to the meter managment company or residents. Safety accidents can be prevented, and a malfunction or failure of a meter can be quickly detected and maintained.
