Description

[0001] The present invention relates to a P-type fire alarm control system using a repeater,

Most buildings, such as apartments, houses, houses, schools, etc., should be promptly informed to the control or control room when a fire occurs, and fire alarm receivers should be installed to protect persons and property and reduce damage caused by fire.

There are various kinds of fire receivers, but analog type P type and digital type R type are mainstream. P type fire receivers are applied to buildings with few circuits and most old buildings. R type fire receivers have many circuits New buildings and various functions.

The present invention is to provide a P-type fire alarm integrated control system using a repeater, which can realize various functions such as an R-type fire receiver by installing a repeater in the P-type fire receiver among the above receivers.

As the number of fires increases over the years, the number of applications for intellectual property rights to prevent and early suppress fire accidents that increase in size is increasing rapidly, and the related technology is gradually developing in connection with computer and communication technology.

In this regard, the prior-filed technology is disclosed in Patent Registration No. 100761234 entitled "Integrated control system, server and method using linkage between control services", "Automatic fire breaking system and method using wireless image and integrated method for this" Hundreds of applications can be found, and the number of overseas papers and patent applications is considerable.

However, although the above-described technology is not applicable to hundreds of millions of P-type fire receivers installed in conventional buildings, even if the fire detection and control system is advanced, the existing P- It will be meaningless before the technology is applied.

The present invention is intended to enable efficient and various control functions such as an R-type fire receiver without demolishing a P-type fire receiver having already installed several hundreds of thousands of existing buildings.

P-type fire receivers are unidirectional communication, and fire information is transmitted along a corresponding one-to-one line from a fire detector. Typical fire information is a voltage drop of current flowing in a wire.

P-type fire receivers are installed in a safe place from fire. Generally, they are gathered in a terminal in a receiver so as to be gathered along a wire from a fire detector installed at various points, and a fire receiver is visually observed by a manager.

However, it is not an exaggeration to say that the risk of fire is increasing as the management of the P type receiver becomes poor due to the fact that the manager is lacking and the sensor is getting old as the age changes.

In order to solve the above problems, it is possible to install a repeater as shown in the present invention inside the P-type fire receiver to instantly detect whether there is an abnormality in the fire detector or not. So that the same effect as that of the R type receiver can be obtained.

By installing the repeater in the P-type receiver, it is possible to manage the fire detector information and fire information in the control room without replacing the existing P-type fire receiver, and effectively manage a large number of buildings with low cost and low manpower can do.

In the present invention, a repeater is installed inside a P-type fire receiver to establish an integrated control system capable of checking and controlling a fire detector in the control room to determine whether there is an abnormality or a fire.

As a means for achieving the above object, a repeater installed inside a P-type fire receiver will be described with reference to the drawings.

1 is a front view and a perspective view of a repeater installed in a P-type fire receiver.

The P-type fire receiver is a terminal terminal box that collects fire information transmitted along a wire from a fire detector installed at each point of the building. It serves to transmit position information, fire information, and alarm means of the detector to an administrator or an official .

A repeater 10 is installed inside a P-type fire receiver composed of the above terminal terminal box. The repeater has a substrate 20 constituting an electric circuit in the upper and lower housings.

The relay housing is made of plastic of a flame retardant material and constitutes opening / closing means 10-1 for checking and protecting the substrate from the outside.

In addition, the concave joint 10-2 and the convex joint 10-3 are formed on the side wall of the housing so that the plurality of repeaters are arranged in a line.

A substrate 20 constituting an electric circuit is built in the repeater. The substrate is composed of an ID switch 20-1, an input / output terminal 20-2 composed of a plurality of pins, a display lamp 20-3 Other MCUs and communication input / output terminals.

The ID switch assigns an address to each repeater, and the MCU of the repeater converts the information from the fire detector into a digital signal and sends it to the central monitoring device via the communication line, thereby realizing accurate position and state of the fire information.

In the input terminal, the wires connected from the fire detector are connected to each end like the P type fire detector, and the MCU configured on the board checks the voltage of each terminal and checks whether the fire detector is abnormal or not.

For example, the normal voltage of a fire detector is maintained at 20 ~ 24V, and when a fire occurs, the voltage drops to 2 ~ 7V and the fire receiver recognizes the voltage drop as a fire. The repeater periodically checks the voltage, It is also possible to transmit a signal indicating that an abnormality has occurred to the sensor and the electric wire by transmitting a voltage state gradually lowered according to the influence of the short circuit or noise of the electric wire and the electric wire to the central monitoring apparatus and checking the signal for a predetermined period.

2 is a front view of a connection joint structure of a repeater.

As described above, since the concave joint 10-2 and the convex joint 10-3 are formed on the side wall of the repeater housing, when a plurality of repeaters are installed, they are interlocked with each other to be easily aligned with each other.

3 is a front view of an embodiment of a repeater attached to a P-type fire receiver.

In this figure, two repeaters are connected in series so as to have an input terminal sufficient to accommodate the number of wires that are drawn into the P-type fire receiver 30 from the fire detector It is an installed picture.

4 is a system diagram of a P-type fire alarm integrated control system using a repeater.

In this figure, the repeater is shown outside the P-type fire receiver to help understanding, and the repeater will be installed inside and outside of the P-type fire receiver as needed.

The P-type fire alarm receiver integrated system using the repeater will be described as follows.

A repeater having a terminal that can correspond to one to one as many as the number of wires entering the P-type fire receiver from the detectors S-1, S-2, S-3, Or installed outside.

The input terminal of the repeater is checked by the MCU to check whether the detector is abnormal or not, and it is transmitted to the central monitoring unit of the integrated control room through the communication line connected to the inside of the repeater.

If a P-type fire alarm receiver integrated control system is constructed without the repeater as described above, it is necessary to connect dozens to hundreds of wires as many as the fire detectors through the P-type fire receiver to the integrated control room. This not only saves these costs, but also makes it easier and quicker to build an integrated control system.

In the event of a fire, the central monitoring device signals the alarm connected to the place where the fire occurred, and the fire alarm is transmitted to the central monitoring device of the integrated control room. It makes an audible alarm, and sends the situation to the fire department and the manager by wire or wireless communication.

In addition, in the figure, the output stage displayed on the repeater is configured to utilize the fire detector in addition to fire information and various other data of the repeater to the central monitor device for inspection and remote control of the device.

Hereinafter, the central monitoring unit of the integrated control room can be configured to be linked with the web-based Internet communication, or an advanced integrated control system such as a method system and an R-type fire receiver, , It is possible to monitor the inside of the building in real time or to be notified of crime prevention information and fire information with SMS text.
