Description

GAS IMFORMATION OUTPUT APPARATUS AND METHOD OF A ELECTRONIC DOOR LOCK}

The present invention relates to a gas information output device and method for an electronic door lock, and more particularly to an electronic door lock which detects a gas state at a corresponding point in time when a resident's door lock is operated and outputs various voice messages regarding gas information to the resident. The present invention relates to a gas information output apparatus and a method thereof.

As is well known, conventional electronic door locks and general door locks can perform only functions related to opening and closing of a door and security. These door locks are mechanical and electronic, and the electronic mechanical door lock is composed of a lock and a key and has a function of locking or unlocking the door. These mechanical door locks have many security risks because they can lose keys or facilitate key cloning.

In the case of the electronic door lock, a key input unit comprising a plurality of key buttons, a control unit for determining an input signal of the key input unit and outputting a control signal, and driving a solenoid with the control signal of the control unit to lock or unlock the door. Door opening and closing means. In addition, the electronic door lock is configured with a bell button such as an interphone to be used when a visitor calls a person in the house.

However, in the case of the conventional electronic door lock, only the function of locking or releasing the door as described above and the function of calling a person in the house guide unit are configured. Therefore, there is a problem that a resident who returns after going out cannot check the status of the house. In particular, in the case of gas leakage, if there is a gas leak while the occupant is out, there is a problem that the occupant may enter the house without knowing it at all, and thus may be easily exposed to danger. Even in the case of the prior art, there is a problem in that it is not possible to recognize whether the gas leaks or whether the gas pressure is unstable at all, since the state of gas leakage and the presence of pressure abnormality of the gas cannot be confirmed.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-described state of the art. An electronic door lock gas information output device for detecting a gas state at a corresponding point in time during a door lock operation of a resident and outputting various voice messages for gas information to the resident. And to provide a method thereof.

3 is a flowchart illustrating a signal flow of a gas information output apparatus of an electronic door lock according to an embodiment of the present invention.

First, the user sets the reference pressure of the gas through the gas reference pressure setting unit 104 provided in the indoor unit 100 (first step: ST-1). When the gas pressure data detected through the gas pressure detector 102 is applied to the controller 216 (second step: ST-2), the controller 216 compares the gas pressure with a preset reference pressure. It is determined whether the gas leaks (step 3: ST-3).

If the gas pressure is less than the reference pressure, the controller 216 determines that the gas is leaking and issues a warning about the gas leakage through the bell 112 (fourth step: ST-4).

In addition, the open state of the intermediate valve 52 is detected through the valve state detecting unit 106 (step 5: ST-5), and at this time, the user wants to go out to generate an operation signal through the door lock device 210. (Step 6: ST-6), the controller 216 determines whether the intermediate valve 52 is open (step 7: ST-7).

If the intermediate valve 52 is open, the controller 216 drives the speaker 214 to warn that the intermediate valve 52 is open (step 8: ST-8).

First, even when the user goes out, the control unit 216 receives and compares the gas pressure data continuously from the gas pressure detection unit 102. As a result of comparing the reference pressure and the detected pressure in the control unit 216, the gas pressure is increased. If it is less than the standard pressure, it is determined that the gas leaked.

In this state, when the control unit 216 determines whether the user wants to release the door by using the door lock device 210 and the signal for door release is detected, the control unit 216 reads the gas leak information. The voice is output through the speaker 214.

In addition, the present invention may display the current gas pressure information through a screen (not shown).
