Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an address-based repeater and an address-

The present invention relates to an address type repeater and an address type fire detector based on location information included in an automatic fire detection system.

In recent years, the shape of buildings has been increasing in height, underground, and larger due to the improvement of land efficiency and landmark tendency. This tendency is becoming a trend of buildings not only in Korea but also in the whole world. In addition, the complex is being developed as a multiplex type building in which commercial facilities for various purposes such as theaters, restaurants, shopping centers, karaoke rooms,

However, it is clear that the increase in the number of commercial buildings in the building space, the increase in the underground space, the enlargement in the building space, and the increase in the internal division and the use of various interior materials due to the splendid interior, to be.

As a result, the importance of fire fighting systems to prevent, alert, and suppress fires is growing. Among them, the automatic fire detection facility performs fire extinguishing and early suppression through control of fire extinguishing facility and ventilation facility linked with safe evacuation guidance through primary detection and early warning of fire, It is a firefighting facility that plays a pivotal role to play.

Fire safety standards of automatic fire detection equipment (NFSC 203) Article 3 Definition of terminology defines representative devices of automatic fire detection equipment as receiver, repeater, detector, and transmitter as follows. A receiver is a device that directly receives a fire signal from a detector or a transmitter or receives it through a repeater to indicate and alert the occurrence of a fire. A repeater is a device that receives a signal according to the operation of a detector, a transmitter or an electrical contact, and transmits the signal to a control panel of the receiver. Detectors are devices that automatically sense heat, smoke, flame or combustion products that occur during a fire and send it to the receiver. The transmitter is a device that sends a fire signal to a receiver manually.

Currently, the domestic transmitter is a 4-wire type of circuit (input) line, common line, answer line, and telephone line, and thus has a PUSH button switch, a response indicator, and a telephone jack. The operation method is a one-dimensional method of transmitting ON / OFF contact signal by simply pressing the PUSH button switch. The response line is able to confirm the operation of the transmitter even when there is no response line due to the development of the power line communication technology, and to keep the response indicator lamp on and on. In addition, the telephone function using the handset's handset is introduced to the maintenance of the facility in the 1980's, and is a dancing function that is not currently used as a mobile phone, and a handset must be provided for the telephone function, It is virtually unnecessary because it is not available anywhere.

On the other hand, according to the fire position display function of the present automatic fire detection apparatus, most of them display only a wide fire position in the boundary zone unit, but do not indicate the detailed fire position in the detection zone unit. Therefore, there is a problem that it is very difficult to accurately locate a fire when a fire occurs in a complex internal structure, a compartment in a room, and a large space. In other words, conventional repeaters have the problem that adaptability is considerably deteriorated in buildings with a complex internal structure and large-scale buildings, which have a high risk of fire, as in conventional fire receivers and detectors.

FIG. 1 is an illustration of operation characteristics of a conventional repeater and a detector.

As shown in FIG. 1, the fire detectors connected to the repeater are characterized in that, when one detector is operated per one input circuit, the detectors on the same circuit line are not operated. Thus, there is a limit to the operation of the subsequent detectors because the supply voltage drops sharply due to the voltage drop during the operation of the detector. Further, in order to solve the problem of the conventional detector, even if the address type detector is connected to the existing repeater, problems of signal processing may appear.

FIG. 2 is a characteristic view showing a characteristic of a detector operating position indication of a repeater and a receiver in a fire in the related art.

As shown in FIG. 2, in the case of a conventional repeater, only the fire position of the boundary zone unit is received by the receiver, and the accurate fire position of the operated detector can not be confirmed. Therefore, it takes a long time to find the exact fire position in case of a fire, which causes a problem of delaying the initial action in a fire situation in which one minute is one second.

Also, conventionally, in the case of a repeater, a repeater number is set through a dip switch in the field, and there is no display function for confirming a set address. Therefore, there are a lot of difficulties in setting the address in the field, such as an error in the address setting and communication error with the receiver due to the inexperience of the address setting of the beginner. In other words, there are many complaints in terms of maintenance in the field. As an example, the number of DIP switches is set to 1, but the problem of recognizing the pins as zero because they do not raise the pins certainly is on the spot. In order to check the location of the fire in case of fire, The facility manager can not confirm the location of the fire when a fire occurs during the building patrol, which can cause enormous damage due to delayed confirmation of the location of the fire.

In addition, the firefighting facility manager checks the location of the fire and firewalls through the receiver, and looks for the repeater at the place for the initial response. Remembering the number of the repeater operated in the urgent situation depends on the individual's ability Differences can appear, but it is a very difficult reality.

In addition, in order to check the repeater number at the site, there is a problem in that the number of the repeater's DIP switch cover must be checked after opening the cover.
