Description

Fire-prevention system capable of earthquake detection {fire-prevention system possible earthquake observation}

The present invention relates to a fire prevention and disaster prevention system, and more particularly, to a fire prevention and disaster prevention system, in which a differential analysis of a shaking motion in a building is performed in real time to notify an earthquake warning notification when an earthquake occurs and to switch a normal power state to an emergency power state, And a fire fighting system capable of detecting an earthquake.

Currently, disaster prevention systems are designed to enable disaster management at large buildings and subway stations in the event of a disaster. In addition, the facility uses sensor detection signals such as fire sensors to identify disaster situations and actively cope with them. .

However, since such a station is located within the building or the history of the disaster, it can not be free from the disaster, and when the disaster is intensified, the disaster may reach the station and the station may lose control.

In this case, since the internal countermeasures become impossible, there arises a problem that the disaster prevention center such as the firefighting disaster headquarters can not but depend on external disaster prevention activities.

On the other hand, the alarm system is used when it is necessary to prevent damage by alarming the person when an alarm situation occurs in case of fire, security or safety.

Conventionally, when a dangerous situation such as a fire, an earthquake, or a gas leak occurs in a house or a building, a certain detector notifies an occupant or a building user of a dangerous situation by making an alarm sound. That is, if a fire or gas leakage occurs in a certain place such as a house or an office, a sensing device operates to activate a visual or audible alarm to confirm to the user. In addition, there may be a case where a danger warning service is provided in order to prepare for a dangerous situation by providing an automatic communication for contacting a relief facility such as a fire department or a police station for requesting assistance according to the operation of the alarm device.

Such a conventional emergency alarm system continuously provides a warning sound or a visual warning light to the user, but it is difficult for the user to know the exact position of the area where the disaster occurred and the dangerous situation.

Even if there is an automatic communication system with a fire department or a police station, it is only communicated to some system connected by a private line.

Therefore, in a case where a user does not know the structure of the building, for example, a case where the user can not quickly cope with a dangerous situation may cause a great damage. In addition, in the conventional automatic liaison system, users are unconditionally connected to the relief management system without being able to confirm them, so that when the relief management system is slightly delayed, it may be difficult to quickly cope with a dangerous situation.

In order to solve the above problem, the present invention provides a differential analysis of the shaking motion in a building in real time to notify an earthquake warning when an earthquake occurs, and to switch a normal power state to an emergency power state to increase a safe effective operation time And an object of the present invention is to provide a fire prevention system capable of detecting an earthquake.

According to an aspect of the present invention, there is provided a fire prevention system capable of detecting an earthquake, the fire detection system being attached to a ceiling or a wall of a building to detect a fire occurrence signal of at least one of heat, smoke, A fire receiver for controlling the fire fighting equipment in the building by receiving a fire signal from the fire detector to determine whether the fire is present or not and outputting a control signal to the fire detector, A fire detector for detecting a fire occurrence signal detected from the fire detector to amplify and transmit the fire occurrence signal to the fire receiver to receive and process the fire occurrence signal; To the fire receiver; And a terminal for wirelessly receiving the fire or seismic information and transmitting the fire or seismic information to an upper manager when a fire or an earthquake occurs in the fire alarm receiver and the control signal is output to the fire alarm detector.

The fire fighting system capable of detecting an earthquake according to the embodiment of the present invention has the following effects.

First, differential analysis of shaking in buildings can be performed in real time to notify an earthquake warning when an earthquake occurs, and to switch the normal power state to the emergency power state to increase the safe effective operation time.

Second, by analyzing vibration caused by earthquake and general vibration, seismic alarm can be detected by converting the color of fire detector and guidance light so that people in the building can evacuate through visual alarm.
