2 is a block diagram of a fire alarm system equipped with a self-diagnosis system according to an embodiment of the present invention.

The term used in the present invention is a general term that is widely used at present. However, in some cases, there is a term selected arbitrarily by the applicant. In this case, the term used in the present invention It is necessary to understand the meaning.

Hereinafter, the technical structure of the present invention will be described in detail with reference to preferred embodiments shown in the accompanying drawings.

FIG. 1 is a block diagram of a fire alarm system according to an embodiment of the present invention. FIG. 2 is a block diagram of a fire alarm system having a self-diagnosis system according to an embodiment of the present invention .

Referring to FIGS. 1 and 2, a fire alarm provided with a self-diagnosis system according to an embodiment of the present invention includes a main body 110 having a main contact 111.

At this time, the main body 110 may have various materials and shapes, and therefore, the present invention is not limited thereto.

A general fire alarm is fixed to a wall or a ceiling of a home, an office or a factory. To this end, the fire alarm is detached from the main body 110 at the other side of the main body 110, The bracket 150 is connected.

That is, the main body 110 is fixed to the wall surface or the ceiling of the room where the fire is likely to be generated by the bracket 150 detached from the main body 110.

Meanwhile, the fire alarm provided with the self-diagnosis system according to an embodiment of the present invention includes a thermal unit 120 coupled to one side of the main body 110.

At this time, the thermosensitive part 120 is formed of a thermosensitive room in which the internal air of the thermosypheric part 120 expands and the internal pressure increases when the external temperature rises due to fire.

At this time, a leak hole 133 for preventing the thermally conductive portion 150 from being exploded by the expanded air is provided in the thermally conductive portion 120 as shown in FIG.

Meanwhile, an alarm generating unit 130 for generating a fire alarm when the internal pressure of the thermosensitive part 120 rises is provided in the thermosensitive part 120.

The alarm generating unit 130 includes a diaphragm 132 having an auxiliary contact 131 that is grounded with the main contact 111 when the internal pressure of the thermosensitive unit 120 rises.

The diaphragm 132 refers to a partition plate of an elastic thin film and may be formed of various materials such as natural rubber, synthetic rubber, and metal plate.

That is, in the fire alarm system equipped with the self-diagnosis system according to the embodiment of the present invention, heat is generated due to the occurrence of fire, and the internal air of the thermosensitive part 120 is expanded by the generated external heat. The internal air of the diaphragm 132 is pressurized to raise the diaphragm 132 so that the auxiliary contact 131 formed on the diaphragm 132 is grounded with the main contact 111 to operate the alarm generating unit 130 .

Meanwhile, the conventional fire alarm has a problem in that the fire alarm is operated only when a fire actually occurs, so that damage is incurred due to the incapacity of the fire alarm even though the actual fire occurred.

Accordingly, the fire alarm provided with the self-diagnosis system according to an embodiment of the present invention generates heat for self-diagnosis by a power source provided inside the thermosensitive part 120, And a heat generator 140 for raising the internal pressure of the alarm generator 120 to operate the alarm generator 130.

That is, the fire alarm provided with the self-diagnosis system according to an embodiment of the present invention applies power to the heat generator 140 to heat and expand the internal air of the heat generator 120, And the main contact point 111 are artificially grounded, it is possible to confirm whether the alarm generator 130 is operating.

In this case, the operation of the alarm generating unit 130 means that the smoke alarm is normally operating. If the alarm generating unit 130 is not operated, it means that an unspecified error has occurred in the smoke alarm. It can be seen that replacement is necessary.

The heat generating unit 140 may include various heat generating units capable of raising the internal temperature of the thermosensitive part 120. In an exemplary embodiment of the present invention, Is used as the heating element.

Meanwhile, the fire alarm provided with the self-diagnosis system according to an embodiment of the present invention includes a server for controlling and detecting the operation of the heat generator 140 and the alarm generator 130, And a first communication unit for transmitting the operation state of the alarm generating unit 130 to the server according to the operation of the alarm generating unit 140.

In addition, the fire alarm provided with the self-diagnosis system according to an embodiment of the present invention includes a second communication unit for transmitting the operating state of the alarm generating unit 130 transmitted to the server to the manager's computer or the portable terminal do.

At this time, the second communication unit can use various means, but in the embodiment of the present invention, Wi-Fi or Bluetooth is used.

Hereinafter, the principle of operation of a fire alarm provided with the self-diagnosis system according to one embodiment of the present invention will be described in detail with reference to FIG.

First, in the case of a fire alarm provided with a self-diagnosis system according to an embodiment of the present invention, a self-diagnosis test command is executed through a server for self-diagnosis to determine whether the fire alarm operates normally.

The heat generating part 140 provided inside the thermosensitive part 120 is operated through the self test test command.

At this time, when the alarm generator 130 operates normally, the server which received the notification that the alarm generator 130 has been operated normally through the first communication unit records in the server that there is no abnormality in the alarm generator 130.

On the contrary, the server receiving the notification that the alarm generator 130 is not operated normally records the inability of the alarm generator 130 to operate, and the administrator can not operate the alarm generator 130 State.

In addition, the server records the operation of the alarm generator 130 according to actual fire occurrence, and informs the administrator of the occurrence of the fire through the second communication unit.

At this time, when the actual fire occurs, the server also transmits a fire occurrence to the nearest fire department.

As a result, the fire alarm provided with the self-diagnosis system according to an embodiment of the present invention can automatically diagnose the error and normal operation of the fire alarm through the above-described technical constructions, so that malfunction or malfunction of the fire alarm And the time, manpower and cost for maintenance and repair of the fire alarm are greatly reduced.
