BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gas supply device, and more particularly, to an apparatus and method for generating a gas remote meter reading alarm for detecting a gas supply state, a usage amount, and a gas leak and generating the value remotely.

Unlike households and businesses that use city gas, LP gas is purchased and used by LPG in homes and businesses, and when gas is used, gas is required to be delivered to the gas supplier. Paid.

Recently, however, as the number of homes and businesses that use LP gas has increased, the probability of gas accidents has increased, and the method of measuring the amount of gas filled in the canisters is not easy, so users and suppliers have to change the gas cylinders. There was a fight between the livers.

Therefore, in order to more efficiently manage and prevent such a problem, two or more LP gas cylinders are provided with an automatic switching machine to supply gas from another gas cylinder when the gas filled in one gas cylinder is completely consumed in the two gas cylinders, Has a gas detection sensor that detects a leak and generates an alarm sound, and a meta device indicating the amount of gas used by the user. All gas connection pipes are made of metal pipes.

And the gas use price was also to be paid according to the gas usage amount displayed on the meta machine.

Referring to the conventional LP gas supply device as described above with reference to the accompanying drawings as follows.

1 is a configuration diagram of a conventional LP gas supply device.

In the conventional LP gas supply device, two gas cylinders 1 filled with gas and two gas cylinders 1 connected to the two gas cylinders 1 are filled with one of the two gas cylinders 1 filled in one of the gas cylinders 1. When used, it detects this and selects one of the two gas cylinders to supply gas from the remaining gas cylinders 1, and an automatic switcher 2 for supplying gas, and a meta device 3 for displaying the amount of gas used by the user. And a gas supply pipe (4) for supplying gas from the automatic transfer machine (2) to the gas combustion device (6) through the meta device (3), and attached to a predetermined position of the gas supply pipe (4). It is configured with a gas detection sensor (5) for detecting a gas leak to generate an alarm sound when a gas leak is detected.

The conventional gas supply device configured as described above is installed to be more convenient for the user than the previous gas supply device, but there is still inconvenience in using the gas because it is not possible to accurately grasp the replacement time of the gas container.

That is, when the gas filled in one gas cylinder is exhausted, the gas is automatically supplied from the other gas cylinder, so that the user can eliminate the inconvenience of running out of gas during cooking and check the gas usage, but the empty gas cylinder can be checked. You have to replace it quickly, but you may not recognize it.

Such a conventional gas supply device has the following problems.

First, the gas supplier must read the meta-devices on a regular basis every month and bill the user for the gas usage cost corresponding to the gas consumption. Thus, labor costs are increased.

Second, when the gas in one gas cylinder is exhausted by the automatic transfer machine, the gas is automatically supplied from the other gas cylinder. However, the gas supplier does not know that one of the two gas cylinders is empty, so the gas cylinder is frequently used for smooth gas supply. There is a hassle to check for being empty.

Third, a crime pretending to be a gas meter may occur.

The present invention has been made to solve the above problems, the object of the present invention is to provide a gas remote meter reading alarm generating device and method to automatically notify the gas supplier by detecting the gas consumption, gas replacement time, gas leakage, etc. .

2 is a configuration diagram of a gas remote meter reading alarm generating apparatus of the present invention.

The gas remote meter reading alarm generating device of the present invention is connected to two gas cylinders (1) filled with gas, and the two gas cylinders (1) to one gas cylinder (1) of the two gas cylinders (1) When all the filled gas is discharged, it detects this and selects one of the two gas cylinders to supply gas to supply the gas from the remaining gas cylinder 1, and simultaneously generates a corresponding signal when the gas cylinder is selected.

It is comprised with the generator 7.

Detailed configuration of the remote metering alarm generator in the present invention LP gas remote metering alarm generating device configured as described above is as follows.

3 is a detailed configuration diagram of a remote meter reading alarm generator according to the present invention.

A power supply 11 for rectifying and smoothing commercial power and supplying operating power to each part, a counter 12 for counting real time, and whether or not power is supplied from the power supply 11 and the current data is transmitted. From the display unit 14 for indicating whether the user is operating the telephone number of the gas supplier, its ID, meter reading date, time, initial value of the meta device, etc., and the user's telephone line. When a signal is input from the telephone usage detector 18 for detecting the use of the telephone and the automatic switch 3, the gas sensor 5, and the meta 3, the current telephone is detected from the telephone usage detector 18. The control unit 19 checks whether a call is in progress and dials the set phone number when the phone is not in use, and outputs the corresponding data, and corresponds to the phone number of the gas provider set according to the control signal of the control unit 19. DTMF 16 which generates a signal and oscillates and outputs data generated when an event occurs, and connects a telephone line to a user's telephone or a telephone line to the DTMF 16 according to a control signal of the controller 19. And a relay unit 17 and a memory unit 15 for storing data input from the setting unit 13.

Here, a signal line for detecting a cutting line is connected to an input terminal of the control unit 19 for receiving a signal from the automatic changer 2, the meta device 3, and the gas detection sensor 5. That is, in addition to the signal lines of the automatic transfer device 2, the meta device 3, and the gas detection sensor 5, separate ground and constant voltage signal lines are connected to the input terminal of the controller 19. Accordingly, the controller 19 recognizes that the ground and the constant voltage are disconnected from the ground and the constant voltage signal line.

Operation of the gas remote meter reading alarm generator of the present invention configured as described above is as follows.

4 is a flowchart illustrating a method of generating an LP gas remote meter reading alarm generator according to the present invention.

First, the installation method, as shown in Figure 2, the gas supply from the gas cylinder (1) to the combustion device 6 is made through the gas supply pipe (4) and the automatic transfer machine (2), meta-device (3) gas detection Each signal from the sensor 5 is connected to the input terminal of the remote meter reading alarm generator 7, and the telephone line of the home or business where the LP gas supply device is installed is connected to the telephone of the meter reading alarm generator 7. Connect to the port.

Then, the gas consumption recorded in the current meta device 3, the desired date of the meter reading, the current time, the telephone number of the gas supplier and the ID of the remote meter alarm generator 7 are set through the setting unit 13 ( 1S).

Regardless of whether a signal is input to the input terminal, the counter 12 of the remote meter reading alarm generator 7 counts the real time (2S).

As such, in the state where the gas supply device is installed, the meter 3 which reads and displays the gas use outputs a pulse signal corresponding to the amount of gas used, and the control unit 19 counts the pulse signal to be actually used. The amount of gas is calculated and accumulated (3S).

The gas detection sensor 5 outputs a "low" signal when there is no leaked gas, and outputs a "high" signal when the leaked gas is detected.

Similarly, the automatic changer 2 generates a signal each time the gas supply is switched from one of the two cylinders to the other. That is, when the gas is currently being supplied from the gas cylinder A, when the gas of the gas cylinder A is used up, the automatic switching machine 2 changes the gas supply path so that the gas is supplied from the gas cylinder B. At this time, when gas is being supplied from the gas cylinder A, a "low" signal is output. When the gas supply path changes from the gas cylinder A to the gas cylinder B, the automatic switcher 2 sends a "high" signal. If the gas supplier receives this signal, replaces the gas cylinder (A), and initializes the auto changeover device again, it outputs a "low" signal again.

On the other hand, signal lines (ground and constant voltage signal lines) for detecting a disconnection line are connected to an input terminal input from the automatic transfer device 2, the meta device 3, and the gas detection sensor 5 to the controller 19. Since the ground and the constant voltage signals are not input from these signal lines, the control unit 19 recognizes that they are disconnected.

Then, the signal input from the meta device 3 is counted to continuously accumulate gas usage. When the set date is reached, the currently accumulated value is output (4S).

If a signal indicating that the gas supply is switched from an automatic changer is input (5S), or a gas leaks (6S) or is cut off (7S), the event is notified to the gas supplier regardless of the set date (8S). ).

That is, when an event occurs from the automatic transfer machine 2 or the gas detection sensor 5 or a disconnection event occurs, a data transmission format is immediately established to start transmission, and the event from the meta device 3 is transmitted on a specified date. do.

When the event occurs as described above, it is determined whether or not the connected telephone line is in use (9S), and when the telephone line is not in use, dialing the preset telephone number to start communication with the computer of the gas supplier (11S). Then, the data is transmitted according to the event and the corresponding data is notified to the gas provider's computer or pager (12S).

This process is repeated, so that gas usage and events can be read and transmitted remotely, or an alarm will sound when a gas leaks.

On the other hand, although not shown in the drawings, not only the present invention can be applied to the LP gas supply device, but the present invention can be applied to the existing city gas supply device.

That is, in FIG. 2, the city gas does not need a gas cylinder, and thus does not need an automatic changer. Therefore, the meter displays the gas usage and outputs the corresponding signal, and the alarm that detects the gas leak generates an alarm sound when the gas leaks and outputs the corresponding signal to generate the remote meter reading alarm. You can dial the additional phone number.

As described above, the apparatus and method for generating a gas remote meter changeover alarm according to the present invention has the following effects.

First, since the changeover of the gas cylinder is automatically checked remotely, since only the gas cylinder in the required place can be replaced, the actual logistics cost can be reduced.

Second, the conventional meter readers visited each use place to read gas usage, but the present invention can automatically read gas usage, thereby maximizing labor cost reduction.

Third, it is possible to shorten the meter reading time and obtain accurate meter reading data, thereby improving reliability with customers.

Fourth, crimes disguised as meter readers can be prevented.
