Description

FIELD OF THE INVENTION [0001] The present invention relates to a fire detector having a warning display function and a fire-

In particular, the present invention relates to a fire prevention and disaster prevention system, and more particularly, to a fire prevention and fire prevention system, in which a fire detector having a warning display function and a fire detection function is installed to visually warn the occurrence of a fire and guide the escape route, FIELD OF THE INVENTION The present invention relates to a fire detector and a fire detection system.

Generally, an induction lamp for evacuating a person in an emergency can be divided into an evacuation guidance light and a pathway guidance light. An evacuation guidance light is installed to easily grasp the escape door in an emergency. The passageway guide light is provided to pass through a hallway, And is installed to be able to inform the direction of evacuation in an emergency.

In this way, the guide light is a device that easily tells the direction and evacuation location to the pizza player in case of a disaster such as a fire, and guides the pizza player in that direction. That is, the guide light is required to have high visibility so that the evacuee can easily recognize the position of the emergency exit or the evacuation site, and low power consumption is required so that the emergency battery can be lit by the emergency battery for a long time.

These guide lights are installed on the wall, installed on the floor, and installed on the ceiling, so that people can quickly escape to a safe place in the event of a fire in a building, a subway, or in an emergency.

1 is a block diagram for explaining an operation system and principle of a fire prevention system according to the prior art.

The prior art fire fighting / disinfection system is composed of a detector 10, a transmitter 20, a receiver 30, an alarm / firefighting facility 40, and a fire / location indicating facility 50, as shown in FIG. The fire alarm device 40 and the fire / location display device 50 are operated to apply a fire signal to the fire alarm device 40 and the fire / do. That is, the detector 10 automatically generates a fire signal in the event of a fire, and the transmitter 20 transmits a fire signal when the button is pressed. When the receiver 30 receives a fire signal from the detector 10 and the transmitter 20, the receiver 30 applies an operation signal to the alarm / fire-fighting facility 40 to activate the fire-fighting facility along with the alarm, 50 to indicate fire and location.

On the other hand, the fire fighting and disinfection system according to the prior art monitors the fire in real time and operates the equipment to operate automatically when a fire occurs. These facilities include emergency broadcasting equipment, automatic fire alarm equipment, and three-wire lighting equipment.

Fig. 2 is a schematic diagram showing a fire prevention / disaster prevention system according to the prior art.

As shown in FIG. 2, the conventional fire fighting / disinfection system comprises a plurality of detectors 10, a transmitter 20, and a receiver 30 for each boundary region. Here, the receiver 30 includes a relay 31, which is connected to a fire indicator 32, a globe indicator 33, an alarm facility 34 and a fire station 35, .

A resistor 21 is provided at the end of the transmitter 20 so that only a small amount of current flows. However, when a current equal to or greater than a predetermined value flows through the circuit, the relay 31 operates to operate the fire indicator 32, the earth indicator 33, the alarm facility 34, and the associated fire fighting facility 35 .

The detector 10 functions as a switch 11 in a circuit, and functions to cause a current exceeding a predetermined value to flow. That is, when a fire occurs, the switch 11 is automatically closed to allow a current equal to or greater than a predetermined value to flow. When the person presses the push switch 22, the switch is closed so that a current of more than a certain value can flow.

In the R type system, when the detector 10 or the transmitter 20 operates, a specific communication signal is transmitted to the receiver 30 and the relay 31 is connected to the relay 30, .

Meanwhile, the detector 10 should include a sensor function for detecting a physical or chemical change amount generated when a fire occurs, a determination function for determining whether or not it is a fire, and a transmission function for transmitting a fire signal to a receiver.

Here, the sensor function of the sensor 10 causes physicochemical changes of heat, smoke, and flame (flame). At this time, the detector 10 senses one or two of the physicochemical changes. The sensor 10 senses heat according to an object to be sensed, a smoke detector that detects smoke, a flame sensor that detects a flame, And a hot-melt detector for detecting the temperature.

The determination function of the detector 10 determines that the fire is a fire if the amount of physico-chemical change due to the fire lasts more than a predetermined amount of time. The amount of physicochemical change, which is a criterion for determining that the detector 10 is a fire, is defined in the sensor type approval and verification technical standard rule and is referred to as sensitivity. The sensitivity is classified into scoop, 1, 2, and 3 types, and responds to small changes as the scoop increases. The determination function is generally performed by the sensor 10 itself, but the analog type sensor transmits only the amount of physicochemical change around the sensor to the receiver, and the determination of the fire is made in the receiver.

The originating function of the detector 10 is a fire signal sent to the receiver 30, and includes a contact signaling method and a communication signaling method.

The contact signaling system is a method of establishing a contact point to a wire connected to a sensor from a receiver, and when a current flows, it is a fire.

The communication signal system is a system in which a communication device is built in a detector and a receiver to exchange communication signals with each other. However, since the detector incorporating the communication device is disadvantageous in that it is economically burdensome, the receiver incorporates a communication device and constitutes a signal conversion device for converting a contact signal into a communication signal between the sensor 10 and the receiver. In addition, a sensor having a built-in communication device can send not only a fire signal but also an address of the sensor 10 together. Such a sensor is called an address type sensor.

The principle of automatically closing the switch 11 of the detector 10 is to utilize the expansion force of the air generated by the fire and to change the physicochemical change occurring during the fire into the current flow to close the circuit.

First, the method using the inflation force of air is called a differential type air-type heat sensor. However, when the temperature rises due to the occurrence of a fire, the air in the air chamber expands and pushes up the thin film to close the contact.

A method of converting the current into a current flow is a method of converting the amount of heat, smoke, and flame generated in a fire into an electric current to close the contact by using the electromagnetic force.

In addition, the smoke detector-photoelectric sensor uses the principle that smoke blocks or reflects light, and uses a light emitting element that emits light and a photoelectric element that converts light into electricity. The photoelectric sensor can be of the spot type, the separable type, and the air suction type.

A relay or relay is a device that generates electromagnetic force when a coil is energized by using the principle of an electromagnet to form a contact. A relay is formed inside the detector to convert heat, smoke, and flame generated in a fire into a current flow so that the relay operates to transmit a signal to the receiver.

However, the fire detector of the fire-fighting system according to the prior art has a disadvantage that a separate indicator lamp must be installed as a fire indicator because it includes only a sensor function for detecting a fire, a judgment function, and a calling function.
