Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic fire detection system using an isolator and a loopback type signal line,

The present invention relates to an automatic fire detection system using an isolator and a loopback type signal line

More specifically, a loopback path is applied to a signal line circuit, and an isolator is disposed on a signal line, so that a short failure occurs as well as an open failure. The present invention relates to an automatic fire detection system using an isolator and a loopback type signal line that can minimize the inoperable period due to breakage of a line and a short circuit by blocking a signal line adjacent to a fault even in a situation where the fault occurs.

An automatic fire detection system is an alarm system that detects heat, smoke and flame generated in the early stage of a fire to notify personnel and residents of the fire control object to acoustic devices in order to prevent human and material disasters caused by fire. In addition, in cooperation with the fire extinguishing system, the fire extinguishing system enables the person concerned to initiate the fire extinguishing system, induces residents to escape to a safe place, and provides an electrical system necessary for fire fighting and fire fighting activities.

Korea and Japan classify automatic fire detection systems according to the signaling system. The P-type system is a system in which the transmitter and receiver of each boundary area are connected to the receiver by hard wire wiring to exchange the fire signal with the contact signal. The signaling line is multiplexed through a repeater The way in which fire signals are exchanged is called the R type system.

On the other hand, as the demand for large structures increases, the number of high-rise large-scale buildings and various facilities is increasing. In such a large structure, the automatic fire detection system should not only detect the fire, but also be able to confirm the exact point of occurrence and the change of situation. Recently, as new communication technologies such as Lan, internet, optical fiber and mobile devices become popular, various communication system types are applied to automatic fire detection system, so a standard that can be applied to any kind of system is presented .

In the 2010 edition of the National Fire Alarm Code (NFPA) 72, which was enacted by the National Fire Protection Association (NFPA) and is affecting fire safety standards around the world, the automatic fire detection system Assuming that various communication systems can be applied, Class X is specified for signaling line circuits.

Class X, as defined by NFPA 72 (2010 revision), refers to the Class A Style 7 pathway in the previous 2007 edition.

Figure 1 shows the performance of SLCs (Signaling Line Circuits) specified in NFPA 72 (2010 revision).

As can be seen from FIG. 1, Class X is designed to enable the function of receiving a fire alarm signal even in the event of a short circuit (wire-to-wire short) between signal lines, and the remaining performance is the same as Class A Do.

The main performance of Class A stipulates that it is possible to receive fire alarm signal even in case of single failure or simultaneous failure of open and ground. ) Can be implemented by constructing a loopback pathway.

FIG. 2A shows a conceptual diagram of an automatic fire detection system to which a general radial path type of a signal line satisfying Class B is applied.

2A, one side of the signal line 500 is connected to a receiver 100, and a plurality of detectors 200-1, 200-2, 200-3 and 200 are connected, When a fire occurs, a fire signal is generated and the receiver can detect a fire situation.

FIG. 2B is a conceptual diagram of a situation where an open failure and a short failure occur in the automatic fire detection system of FIG. 2A.

Referring to FIG. 2B, if an open failure and a short failure occur in the signal line 500, the line is not operated normally, and communication with the detector 200 is interrupted.

If an open fault only occurs, the connection to the detector 200-4 located after the fault location is disconnected based on the arrangement order on the signal line, and the closer the fault occurrence point is from the receiver 100 The number of detectors that are disconnected can increase.

Short faults are much more fatal than single faults. A short circuit failure is a kind of failure that makes the entire signal line to a state of communication disconnection even if only one fault occurs and also it is difficult to find a fault position as compared with a short circuit failure.

FIG. 3 is a conceptual diagram of a situation where an open fault and a short fault occur in an automatic fire detection system of FIG. 2A in a state where an isolator 400 is applied.

Referring to FIG. 3, a plurality of isolators 400 are disposed between the detectors on the signal line, thereby separating the signal line after the fault point in the case of a breakdown fault and a short circuit fault, The detector and the receiver itself, and the operation of the detector can be maintained in a normal state. Particularly, when an isolator is not used, the alarm system of the entire signal line stops when a short fault occurs. By operating the isolator as shown in Fig. 3, the signal line after the short fault location is separated, The function of the detector can be operated normally.

FIG. 4 shows a conceptual diagram of a situation where an open fault and a short fault occur in an automatic fire detection system constituting a loopback pathway.

As shown in FIG. 4, when the loopback path is applied, since the detector is bi-directionally connected, in the case of a single wire failure, all detectors operate normally and communication is possible. However, in the event of a short-circuit failure, the entire signal line is still affected, and the situation in which the entire signal line can not be used is not improved.

As described above, since communication devices, which are various types of wired / wireless communication devices, can be applied to an automotive person detection system due to the development of communication systems and devices, NFPA 72, which is the most influential fire safety standard, Also defines Class X that normally operates as an alarm. Therefore, a loopback path is applied to the signaling line circuit, and an isolator is disposed on the signal line to cause a fault even in the case of a short failure as well as an open failure. It is required to develop an automatic fire detection system using an isolator and a loopback type signal line that can minimize the inoperable period due to breakage of a line and a short circuit by blocking an adjacent signal line.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. However, the detailed description of known functions and configurations incorporated herein will be omitted when it may unnecessarily obscure the subject matter of the present invention.

The same reference numerals are used for portions having similar functions and functions throughout the drawings. Throughout the specification, when a part is connected to another part, it includes not only a case where it is directly connected but also a case where the other part is indirectly connected with another part in between. In addition, the inclusion of an element does not exclude other elements, but may include other elements, unless specifically stated otherwise.

Hereinafter, the configuration and functions of an automatic fire detection system using an isolator and a loopback type signal line according to an embodiment of the present invention will be described.

FIG. 5 is a conceptual diagram of an automatic fire detection system using an isolator and a loopback type signal line according to an embodiment of the present invention.

Referring to FIG. 5, an automatic fire detection system according to an embodiment of the present invention includes a signal path 500 as a loobpack pathway, an isolator 400 arranged in series with the detector 200, ). ≪ / RTI >

Since the isolator 400 is disposed in the signal line 500 formed by the loopback path, the signal line outside the section where the short circuit or the single wire failure occurs and the detector disposed in the section can operate normally. That is, two isolators adjacent to the area where a short fault or open fault occurs isolate the fault line and the signal line of the stationary area to form an isolation zone.

As shown in FIG. 5, the isolation zone A includes a fault zone, which is isolated from the normal zones B and C, so that the zones B and C are protected from overcurrents due to faults occurring in the isolation zone A, So that circuit breakage can be prevented. In addition, it can be confirmed that both Zone B and Zone C are capable of normal communication with the receiver in the bidirectional connection with the receiver based on the isolation zone A.

Therefore, in the automatic fire detection system according to one embodiment of the present invention, even if an open failure or a short failure occurs in the signal line 500, the isolator 400 disposed near the failure operates By separating part of the faulty line from the normal line area, it is possible to minimize the incommunicable section between the receiver and the detector due to the fault, and to use the isolator and loopback type signal line A fire detection system is provided. In addition, it is possible to protect the detector and the receiver of the normal line area in a circuit by preventing the occurrence of an overcurrent or a short-circuit current in the event of a short fault.

The isolator 400 includes a current sensor 430 for sensing an overcurrent or a shortcircuit current and detects whether an overcurrent is generated and transmits an operation signal to the isolator relay 440 to be connected to the isolator relay Both sides of the signal line are cut off.

Also, it is possible to isolate the signal line by receiving a fire generation signal including the contact signal from the detector 200. The sensor 200 or the signal line at the fire occurrence position is not only damaged but also can be expected to suffer from a short circuit failure or a short circuit due to the breakage. Therefore, if a fire is detected in the detector, the detector position can be isolated in advance.

Short-circuit current or overcurrent due to short-circuit failure is a very large current value, and the related equipment may be damaged. A short circuit failure is a circuit in which the load resistance at both ends of a signal line becomes zero in a circuit concept, and is generally expressed by a short circuit or a short circuit.

However, when the wire is very thin, the wire heated to a high temperature may melt to short-circuit the wire at the moment of shorting. In contrast, when the wire is melted, both ends of the wire are continuously It is possible to maintain the short-circuited state. In this case, the overcurrent or the short-circuit current is broken and various devices connected to the signal line are broken, so that the short-circuited state of the signal line can be solved.

The short-circuit failure and the resulting overcurrent or short-circuit current refer to a current flowing during a very short period of time. From the point of time when the overcurrent is sensed by the internal current sensor 430 of the isolator applied in the embodiment of the present invention, The devices exposed to the overcurrent may be damaged during a period of time until the relay 440 operates and blocks the signal line. Thus, the maximum allowable current of the electrical components used in the isolator is preferably set based on an overcurrent or short-circuit current estimate.

There is also an effect of previously preventing the device breakdown caused by the overcurrent or the short-circuit current by receiving the fire occurrence signal from the detector and isolating the signal line including the detector in advance.

In addition, the isolator includes a sensor connection check section for checking whether the detection is normally connected, so that the detector connection state is checked to generate a sensor connection normal signal to check whether the detector is abnormal due to factors other than a wire breakage or short- It is possible. In particular, it is possible to repeat the occurrence of the sensor connection normal signal at a specific time interval, transmit it to the receiver, and store it so that it can be confirmed by the administrator, thereby making it possible to identify a change in an abnormal situation and establish the most appropriate measure.

Also, as shown in FIG. 5, an automatic fire detection system using an isolator and a loopback type signal line according to an embodiment of the present invention may further include a repeater. In general, a repeater is used to switch a communication signal by receiving a contact signal from an analog detector used with an R-type receiver, or to be used with a P-type receiver and to maintain the voltage of a hard wire wiring.

6A is a conceptual diagram of a sensor built-in isolator applied to an automatic fire detection system using an isolator and a loopback type signal line according to an embodiment of the present invention. In FIG. 6B, FIG. 2 is a conceptual diagram of a repeater embedded type isolator applied to an automatic fire detection system using an isolator and a loopback type signal line according to the present invention.

6A and 6B, the function of the isolator 400 may be installed in the detector and the repeater. That is, when an additional isolator is installed in an automatic fire detection system having a conventional detector and a repeater installed in a certain interval, it is necessary to remove an already installed detector or repeater and install an isolator, It may be troublesome to install a device, and installation space of a device having a different function may be insufficient.

By using the detector or repeater built-in isolator shown in FIGS. 6A and 6B, it is possible to detach and replace the existing detector and the repeater so that the convenience of installation can be realized, and an additional space for installing the isolator is not required Therefore, space utilization can be efficient.

When an overcurrent is detected from the current sensor, the sensed signal is transmitted to the isolator control unit, which transmits an operation signal to the isolator relay to operate the isolator.

When a fire occurrence signal including a contact signal from the detector received at the detector signal receiving unit is received, the isolator control unit can operate the isolator relay and transmit it to the receiver through the isolator communication unit.

The unique number setting unit sets a unique number to each isolator, and assigns different unique numbers to each of the isolators installed in one signal line, and all the isolator information transmitted through the isolator communication unit By including the unique number, the information of each of the quarantine devices can be discriminated and confirmed as a receiver or an administrator. It is also possible to call individual isolators or transmit various control commands at the receiver based on the unique number.

The detector power recovery unit 460 may be used to restore the operating state of the detector to an initial state by turning the detector off and then on again.

The isolator control controls the operation of all components of the isolator and controls the flow of information transmitted from all components that are responsible for the fire signal and the overcurrent signal.

The isolator communication unit may transmit the internal information of the isolator including the operation state of the isolator control unit itself and the operation state of the component controlled by the isolation control unit to the receiver and receive the control command from the receiver.
