Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a gas security system that measures a gas flow rate and shuts off a gas passage when an abnormal flow rate is measured to ensure safety in using the gas.
[0002]
[Prior art]
In recent years, if a gas meter that measures the amount of gas used has been measured for a large flow rate or if it has been used for a long period of time that is not normal, it is judged as abnormal and the gas passage is shut off. The one with a built-in security device to ensure the safety is widespread.
[0003]
And the apparatus which transmits the information in this gas meter as wireless data to the center which manages gas is put into practical use.
[0004]
In addition, water heaters that control the water heater body wirelessly from a remote controller have been commercialized.
[0005]
However, even though the same gas is used, these products operate individually and are considered to be linked by centralized control of terminals, but they are operated as systems that have direct linkage to each other. It wasn't. Moreover, the communication information of cooperation was only the measured value of the gas usage and the associated fee.
[0006]
[Problems to be solved by the invention]
However, for example, when the gas is shut off, the user of the gas cannot easily know that the gas has been shut off, and has to bother to go to the place where the microcomputer meter is installed. In addition, there is a problem that it is difficult to know the state of the microcomputer meter from time to time, such as not knowing when and why the gas has stopped.
[0007]
[Means for Solving the Problems]
In order to solve the above problems, in the present invention, the gas user can easily know the state of the gas meter by notifying the state information of the gas meter from the remote controller of the water heater installed in the house. is there.
[0008]
DETAILED DESCRIPTION OF THE INVENTION
The gas security system according to the first means of the present invention includes a microcomputer meter, a wireless unit that transmits state information of the microcomputer meter as wireless data, a water heater that can receive the wireless data, and controls the water heater. The remote control is provided with a notification unit, and the state information of the microcomputer meter is notified by the notification unit of the remote controller for the water heater, and the microcomputer meter is in a state of shutting off the gas supply to the water heater. Thus, the operation of the water heater is stopped, and the operation of the water heater is resumed in conjunction with the state in which the microcomputer meter starts to supply gas to the water heater .
[0009]
Thereby, a water heater can change operation | movement instantaneously according to gas supply. For example, the status information of the microcomputer meter is taken into the water heater periodically or when the state changes, and the operation of the water heater is changed according to the state of the microcomputer meter, so that the gas is shut off during automatic operation. In such a case, it is possible to stop the hot water heater from burning even if a misfire error occurs normally, and to automatically burn when the gas supply is started.
[0016]
【Example】
Embodiments of the present invention will be described below with reference to the drawings.
[0017]
Example 1
FIG. 1 is a block diagram showing a gas security system according to the means of the present invention.
[0018]
Reference numeral 1 denotes a microcomputer meter mainly composed of a gas flow rate measuring unit, a gas passage blocking device, and a control unit. A wireless unit 2 transmits and receives various state information of the microcomputer meter as wireless data. 3 is a water heater with a built-in device capable of transmitting and receiving wireless data. Reference numeral 4 denotes a remote controller for controlling the water heater 3, and 5 is a notification unit provided in the remote controller 4.
[0019]
According to the first means of the present invention, when the microcomputer meter 1 stops the gas by the built-in shut-off device due to abnormal gas flow, etc., the shut-off information of the micro-meter 1 is transmitted as wireless data by the connected radio unit 2 Is done. The water heater 3 that has received the wireless data notifies the state of the microcomputer meter through the notification unit 5 of the connected remote controller 4 and the reason why the microcomputer meter is shut off as a signal or sound.
[0020]
As a result, the gas user can know that the gas has stopped without having to bother operating the gas device or checking the display of the microcomputer meter. You can also know if it has stopped, making it easier to deal with.
[0021]
Gas shutoff information is also distinguished by the reason of shutoff such as gas flow rate, time, alarm, seismic detector, center, etc., gas leak controlled by microcomputer meter, built-in battery voltage drop, gas pressure drop, etc. Any information such as various warnings and meter reading values may be notified as necessary, or a display unit may be provided on the remote controller 4 for display.
[0022]
(Example 2)
According to the second means of the present invention, when the water heater 3 is wirelessly controlled by the remote controller 4, the wireless data having the information of the microcomputer meter 1 transmitted by the wireless unit 2 is directly transmitted to the remote controller 4. Receive and broadcast.
[0023]
Thereby, since the remote control can directly receive the wireless data of the microcomputer meter without going through the water heater main body, the gas user can know the state information of the microcomputer meter without more time loss.
[0024]
(Example 3)
According to the third means of the present invention, the state information request switch 6 of the microcomputer meter 1 is provided on the remote controller 4, and when this is pressed, a state information request command is sent to the microcomputer meter 1, and the microcomputer meter is wireless data. By returning state information in response to this, the state at that time is notified by the notification unit 5 of the remote controller.
[0025]
As a result, the gas user can check the abnormality of the gas meter located at the source of the gas supply by simply pressing a switch when there is an abnormality in the gas equipment. It becomes easy to identify whether it is in the equipment or the gas meter.
[0026]
Even if the notification of the microcomputer meter status information in the first and second embodiments cannot be received, it can be heard again by pressing the status information request switch.
[0027]
Example 4
According to the fourth means of the present invention, the state information of the microcomputer meter 1 is periodically or when the state is changed, wirelessly communicated and taken into the water heater 3 to change the operation of the water heater into the state of the microcomputer meter. Change it to match.
[0028]
As a result, even if the gas is shut off during automatic hot water filling operation or otherwise, a misfire error will occur and the hot water filling will not be completed, the water heater will stop burning and the gas supply will stop. When started, it can automatically burn and resume hot water filling.
[0029]
In this embodiment, the state information requesting switch is described as the state information requesting unit, but the present invention is not limited to this. For example, the status information requesting unit may make a status information request periodically, or may make a status information request when a person approaches in conjunction with a human detection sensor without being limited to a switch.
[0030]
【The invention's effect】
As is apparent from the above description, according to the gas security system of the present invention, the status of the microcomputer meter is sent to the water heater as wireless data, and the received water heater notifies the connected indoor remote controller as a signal or sound. So, even if the gas stops, the gas user does not have to check the operation of the gas equipment or go to the place where the microcomputer meter is installed, and can know why the gas has stopped. So it becomes easier to deal with.
