Description

IOT-based voice recognition gas safety cut-off system {IOT-BASED VOICE RECOGNITION GAS SAFETY CUT-OFF SYSTEM}

The present invention relates to a gas safety blocking system, and more particularly, to an IOT-based voice recognition gas safety blocking system.

In general, in the home, a gas range or induction is frequently used.

A gas stove or induction can be very cautious and dangerous in that it provides convenience for life, but acts as a major cause of fire.

In the past, as shown in the registration utility model 20-0329025, fire was recognized mainly by detecting smoke from cooked foods. As a more advanced form, there is a method of automatically shutting off a gas valve by measuring the temperature of cooked food in Korean Patent Publication No. 10-1583193 and detecting whether there is a user nearby.

This method is very encouraging in that it can prevent fire in advance before smoke is emitted, and it is very practical and efficient in that it adjusts an alarm or shut-off of a gas valve depending on whether the user is cooking or not.

However, this configuration only blocks the gas supply by itself without the user, and when the user is in a remote location, the gas is blocked or the danger thereof is not recognized at all.

Depending on the cooked food, it may be heated or boiled for a long time. For example, if you are brewing beef bones or making broth for a long time, you may have to stay away from home 24 hours a day. Even in the case of restaurants, if you brew broth for a long time, you may get stuck in cooking and do not see any other business.

Accordingly, there is a need for a means to more efficiently control and monitor cooking heating appliances such as a gas stove or induction even at a remote location in a home or restaurant.

Meanwhile, among gas accidents that occur every year, the number of gas accidents caused by user carelessness in houses occupies the first place, and due to such a fire, many lives and property damages have occurred due to the expansion of fire to the surrounding area as well as the location of the fire. I'm doing it.

In order to prevent this, the installation of an overheating prevention device on the gas stove has been mandatory since 2013, but the implementation is still insignificant.

In order to prepare for this, social welfare institutions are distributing gas safety breakers free of charge to disabled households and aging households, but the use of the vulnerable groups, including the visually impaired, was very limited because the equipment was customized only for normal people.

In addition, the second knob detection sensor 81 is formed of a proximity switch, etc. and is installed on one side of the operation knob 7 to detect the fire extinguishing operation state of the operation knob 7. The operation knob 7 rotates clockwise so that the operation knob 7 returns to its original position while the gas stove is ignited, and the second knob detection sensor 81 is a state in which the operation knob 7 returns to its original position. It is configured to be able to detect.

In the above, the first knob sensing sensor 81 and the second knob sensing sensor 83 of the present invention have been described as being made in the form of a proximity switch, but are not limited thereto, and the ignition start operation and fire extinguishing operation of the operation knob 7 It goes without saying that if it is a configuration capable of detecting the state, it may be composed of other sensors such as an optical sensor.

The control unit 51 of the present invention opens the gas valve 40 when a detection signal is received from the first knob detection sensor 81, and when a detection signal is received from the second knob detection sensor 83, the gas valve ( 40) is configured to block.

Therefore, compared to a method in which the user manually rotates the gas valve as in the past, the present invention automatically opens the gas valve 40 when the user presses the operation knob 7 to rotate the gas. The gas stove is supplied and ignited, and the gas valve 40 can be automatically shut off by simply turning the operation knob 7 to its original position after the gas stove is used up.

Hereinafter, an IOT-based voice recognition gas safety blocking system according to a second embodiment of the present invention will be described with reference to FIGS. 6 and 7.

The second embodiment differs from the first embodiment in that the configuration of the beacon 80 is added and the remote controller 70 further includes an additional function.

Compared to the first embodiment, the remote controller 70 of the second embodiment includes the number of transmissions 71, the position recognition sensor 72, the voice guide 73, the speaker 74, the recipe DB 74, and the valve control information. It is configured to further include (DB), and the remote controller 70 of the second embodiment includes a transmission unit 71, a position recognition sensor 72, a voice guide unit 73, a speaker 74, a recipe DB 74, It may be configured to include a microprocessor for controlling the valve control information DB. The transmission unit 71, the position recognition sensor 72, the voice guide unit 73, the speaker 74, the recipe DB 74, and the valve control information DB are implemented in hardware, software, or an integrated form of hardware and software. Can be.

In this embodiment, the voice recognition sensor 9 is configured to be provided in the remote controller 70, so that the elderly or the disabled who have difficulty in movement input a voice command to the voice recognition sensor 9 through the remote controller 70, and voice recognition The sensor 9 outputs gas valve control signals, such as a gas valve shutoff signal, a gas valve open signal, and a gas valve shutoff reservation signal, to the control unit 51 through the wireless transmission unit 71 according to the received voice command. 51) is configured to control the gas valve 40 by receiving this gas valve control signal.

In the second embodiment, the gas safety blocking system may be configured such that beacons 80 that transmit beacon signals are installed in each area (kitchen, bedroom, living room, etc.) of the home, and the remote controller 70 It is configured to be provided with a position recognition sensor 72 for receiving a beacon signal output from the beacon (80).

When the location recognition sensor 72 does not receive the beacon signal output from the beacons 80, the remote controller 70 determines that the remote controller 70 is not indoors of the home but is outdoors, Even if the user inputs a voice command through the remote controller 70 and the voice command is input to the voice recognition sensor 9, the gas valve control signal is not output to the control unit 51.

This makes it possible to block the case where children take the remote controller 70 out of the house as a joke and unnecessarily perform a voice command for gas control.

That is, only when the remote controller 70 is located indoors of the home, by limiting the use area to output the gas valve control signal to the controller 51 according to the user's voice command, the voice of the remote controller 70 Gas valve control through recognition can be made more safely.

The remote controller 70 of the present invention may further include a voice guide unit 73.

The voice guidance unit 73 detects whether the gas valve 40 is open through the control unit 51, and when the gas valve 40 is open, the remote controller 70 is provided at predetermined intervals. It is configured to broadcast a request for shutting off the gas valve 40 through the speaker 74.

For example, when the gas valve 40 is open through the control unit 51, the voice guidance unit 73 sends a voice message “Do you want to shut off the gas valve” through the speaker 74 every hour. Configure it to print.

Accordingly, the user checks the shut-off request output from the remote controller 70, recognizes that the gas valve has not been shut off insane, and then inputs a voice command for gas shut-off through the remote controller 70. The voice recognition sensor 9 of the controller 70 recognizes this voice command and outputs a valve shut-off signal to the control unit 51 to block the gas valve 40 to prevent a safety accident.

As described above, the present invention is in a state where the gas valve is unintentionally opened by the user, and when the user is with the remote controller 70 in a living room or in a bedroom away from the kitchen, periodically from the remote controller 70 every predetermined time, Since the gas valve shut-off request is broadcasted, the user can recognize it and manage the gas valve more safely.

In addition, the remote controller 70 of the present invention may be configured to further include a recipe DB 75 and a valve control information DB 75.

The recipe DB 75 may be configured to store and manage recipe information including gas-fired power information for various dishes.

The valve control information DB 76 may be configured to include valve control signal information for gas-fired power information for a corresponding dish stored in the recipe DB 75.

For example, the recipe DB 75 may be configured to include gas-fired power information for beef bone cooking such as strong fire for the initial 3 hours, medium heat for 5 hours after, and weak fire for 7 hours after the bone bone. The DB 76 may be configured to include valve control signal information such as gas supply amount for 3 hours corresponding to gas-fired power information for this bone bone -> 5 hours for gas supply for -> 7 hours for gas supply amount small. .

In the remote controller 70 of the present invention, when a voice command for a cooking menu name is input from a user, the voice recognition sensor 9 recognizes the voice command, and the gas fire power for the dishes voice recognized by the recipe DB 75 The recipe information including information is extracted, and valve control signal information corresponding to the recipe information including the gas-fired power information extracted from the recipe DB 75 is extracted from the valve control information DB 76 to the control unit 51. Print it out.

The control unit 51 controls the gas valve 40 to control the gas supply amount for each time of the corresponding dish based on the valve control signal information output from the remote controller 70, so that the gas stove 1 The firepower can be automatically adjusted for each time zone according to the recipe.

In other words, when the user inputs a voice command of'beet bone' through the remote controller 70, valve control signal information for this beef bone dish (3 hours is the gas supply amount vs. 5 hours is the gas supply amount -> 7 hours) Is output to the control unit 51, and the control unit 51 receives this valve control signal information, and based on the valve control signal information, the gas stove 1 has high heat power for 3 hours, and heat power for 5 hours thereafter. In the middle and subsequent 7 hours, the gas supply amount of the gas valve 40 is automatically controlled so that the thermal power becomes small, and then the gas valve 40 is automatically shut off.

Therefore, the user does not need to manually adjust the operation knob of the gas stove (1) for the corresponding dish (bone), and the fire power is automatically adjusted so that the corresponding dish can be cooked more conveniently and safely, which is convenient for the user. This can be improved.
