Description

{A automatic fire alarm system using an optimized analog detector based on a P-type receiver to reduce non-fire alarms}

The present invention relates to a fire alarm system, and more specifically, to a fire alarm system that provides a more precise fire alarm system and can reduce the incidence of non-fire alarms.

As building spaces become higher-rise, underground, larger, and the number of commercial facilities within buildings increases, internal divisions increase and various interior materials are used for extravagant interiors. In the event of a fire, the scale of damage to life and property is bound to be so great that it is unimaginable.

As a result, the importance of firefighting systems that can prevent, warn, and extinguish fires is increasing. Among them, automatic fire detection equipment induces safe evacuation through primary detection and early warning of fire, and carries out initial fire extinguishment and early suppression of fire through control of linked fire extinguishing and smoke control equipment, and determines the extent of fire damage. It is a firefighting equipment that plays a central role in

Meanwhile, in recent years, smoke detectors characterized by rapid fire detection are mainly used as fire detectors, and among smoke detectors, the photoelectric type, which is simple in construction but has excellent sensitivity, is generally used. However, photoelectric fire detectors that use the scattering phenomenon of light by smoke particles have sensitive detection sensitivity, so false fire reports may be a problem. Here, non-fire alarm means that the fire detection device operates due to factors other than heat, smoke, or flame caused by a fire and issues a fire alarm. In other words, when a fire detector is operating normally, it incorrectly detects a fire due to a cause other than fire. The main causes of these non-fire alarms include malfunctions due to increased humidity in the air during the rainy season, and smoke detector operation due to cigarette smoke or automobile exhaust.

According to the National Fire Information Center of the National Fire Agency, the number of dispatches due to non-fire reports (misidentifications) occurred significantly in July, August, and December. This is greatly affected by moisture in the summer because there is more precipitation than other seasons, and as December enters the winter season, it often occurs due to increased heating demand and condensation due to external temperature differences.

Costs such as dispatching a fire truck due to a non-fire warning and confirming the cause by the relevant person are incurred, and there is a problem that a large loss is incurred due to the inability to quickly respond to a real fire due to the dispatch of a fire truck due to a non-fire warning.

In addition, such a fire detection system is composed of a fire detector, a repeater, a receiver, and a transmitter. Generally, the receiver is divided into a P-type receiver and an R-type receiver, the P-type receiver is used with a general detector, and the R-type receiver is It is commonly used with analog detectors.

In other words, the configuration of the P-type receiver and a general fire detector generates a simple switching function detection signal when the set temperature for detecting fire is measured by the general fire detector, and when a detection signal is generated, the P-type receiver unconditionally sounds a fire alarm. As a system, the latest system consists of an R-type receiver and an analog fire detector. The system directly measures temperature, etc. from the analog fire detector and transmits an analog signal for the measured value to the receiver. The receiver determines whether a fire is detected and issues a fire alarm. In that it rings, it has the advantage that fire detection is more precise and the incidence of non-fire alarms is much lower than that of the P-type receiver system.

However, such an R-type receiver-based system has very high installation costs and a long installation time in that all P-type receivers of the already installed fire protection system must be replaced and used, and the conventional P-type receiver-based system It has the disadvantage of having a high probability of generating a non-fire report due to low measurement precision.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.

Figure 1 is a diagram showing the block configuration of a fire alarm system applying an analog detector based on a P-type receiver 400 according to an embodiment of the present invention.

As shown in Figure 1, the P-based fire alarm system according to an embodiment of the present invention includes a plurality of analog fire detectors 100, a detection signal repeater 200, and a preliminary alarm unit 300 disposed in the fire surveillance area. , It may be configured to include a P-type receiver 400 and an output transmitter 500.

More specifically, the P-based fire alarm system according to an embodiment of the present invention includes a plurality of analog fire detectors 100 that are distributed and deployed in the fire surveillance area and generate and transmit analog detection signals for fire detection in real time. , a detection signal repeater 200 that converts and transmits the signal received from the analog fire detector 100, a P-type receiver 400 that receives and transmits the signal received from the detection signal repeater 200, and Determines whether the signal received from the P-type receiver 400 is a fire signal or a non-fire alarm signal according to a preset fire detection method and generates at least one of a fire alarm signal, a preliminary alarm signal, and a failure signal. The preliminary alarm unit 300 and the P-type receiver 400 or the preliminary alarm unit 300 output a fire alarm or preliminary alarm through an output device, or provide a transmitter 550 to manually output a fire alarm. It may be configured to include an output transmitting unit 500.

As such, the embodiment of the present invention, unlike the conventional P-based fire alarm system, uses an analog fire detector 100 and includes a detection signal repeater 200 for connecting the analog fire detector 100 signal to the receiver. By providing a preliminary alarm unit 300 that detects signals such as fire alarm, non-fire alarm, and malfunction precisely according to a preset detection method when detecting a fire and outputs an appropriate alarm, it is similar to the conventional P type. Not only can it be installed quickly and at low cost using system-based system wiring, but it also provides a high-performance fire alarm system that can reduce the occurrence of non-fire alarms.

More specifically, looking at the components, as shown in FIG. 1, the analog fire detector 100 refers to a device that automatically detects heat, smoke, flame, or combustion products generated during a fire and transmits it to the receiver, It may include a temperature sensor 110 that measures measured values such as heat temperature in real time, a smoke detector 130 that measures the concentration of smoke in real time, and the like.

Fire detectors can be classified into single-signal and multi-signal types depending on how the fire signal is generated. A multi-signal detector is one that has different types or functions such as sensitivity within one detector, and two or more different signals are activated at regular intervals. A detector that emits a fire signal.

In other words, the analog fire detector 100 refers to a detector that emits different outputs such as current or voltage values depending on changes in surrounding temperature or amount of smoke. Conventional general detectors have two types: normal state and fire alarm state. Although it is only an indication of two states, the analog detector has the advantage of increasing the precision of fire detection and reducing the occurrence of non-fire alarms in that it identifies and transmits four states, including contamination alarm and low sensitivity alarm, from each detector.

In addition, the fire alarm system using conventional general detectors maintains its function by having a person directly inspect the detector using the five senses, so if it breaks down after calibration inspection, it cannot be detected through normal surveillance, and there is a risk of false alarm in the event of a fire.

However, the analog fire detector 100 applied to the embodiment of the present invention is a device that transmits an arrangement position detection signal through pre-designed detector wiring and detects fire element measurement information including heat or smoke, and is called from the receiver. Because it always informs you of the status, it has the advantage of notifying a fire alarm and detecting abnormalities in the detector in advance, enabling replacement of defective detectors in advance, and greatly improving the maintenance of system functionality.

And, as shown in FIG. 1, the detection signal repeater 200 receives signals according to the operation of the analog fire detector 100, the transmitter 550, or the electrical contact point, and transmits them to the receiver or preliminary alarm unit 300. This refers to a device that receives a signal from the operation of the analog fire detector 100 or transmitter 550 and transmits the control signal to the preliminary alarm unit 300 or receiver.

The detection signal repeater 200 used in the fire alarm system according to an embodiment of the present invention is a PLC (Power Line Communication) repeater, including a relay circuit connected to the transmitter 550 and analog fire detector 100 wiring. It may be provided including a PLC communication line connected to and an optical communication terminal that can be connected to an external setting change terminal.

The P-type receiver 400 refers to a device that displays and warns of the occurrence of a fire by receiving fire information emitted from a fire detector directly or through the detection signal repeater 200. In the embodiment of the present invention, it is an analog fire detector. Since the signal cannot be received directly from (100), the fire information signal is received through a repeater and transmitted to the preliminary alarm unit (300) or transmitter (550).

And, as shown in FIG. 1, the preliminary warning unit 300 determines whether the signal received from the P-type receiver 400 is a fire signal or a non-fire alarm signal according to a preset fire detection method. It may be a device that generates at least one of a fire alarm signal, a preliminary alarm signal, and a failure signal.

The output transmitter 500 outputs a fire alarm or preliminary alarm through an output device using the signal received from the P-type receiver 400 or the preliminary alarm unit 300, or is provided with a transmitter 550 to manually output a fire alarm. As a device, it may be configured to include a connection terminal 510, an alarm bell 520, an indicator light 530, and a transmitter 550.

In this way, the fire alarm system according to the embodiment of the present invention uses an analog fire detector (100) capable of precise and various measurements, and in order to apply the fire detector arrangement line and P-type receiver (400) that is already installed and used, a preliminary alarm unit is used. By providing (300), it is possible to provide a system that can alert by distinguishing between fire occurrence information, non-fire information, and failure information.

Figure 2 shows a wiring diagram of the preliminary alarm unit 300 used in a fire alarm system applying an analog detector based on the P-type receiver 400 according to an embodiment of the present invention, and Figure 3 shows a wiring diagram of the P-type receiver 400 according to an embodiment of the present invention. This is a diagram showing the detailed circuit configuration of the preliminary alarm unit 300 applied to a fire alarm system using a (400)-based analog detector.

As shown in Figure 2, the preliminary alarm unit 300 is a device provided between the P-type receiver 400 and the transmitter 550, is connected to power from the P-type receiver 400, and has an input circuit and an output circuit. It may be configured to include an optical repeater 310, a relay circuit, a recovery button 320, and a buzzer 340. It receives a fire information signal from the P-type receiver 400 through an input circuit and receives a fire occurrence signal. , non-fire alarm signals, preliminary alarm signals, failure signals, etc. can be distinguished and transmitted to the transmitter 550 through the output circuit.

More specifically, as shown in FIG. 3, the preliminary alarm unit 300 has a recovery button 320 for restoring the alarm state to its original state, and converts the signal received from the P-type receiver 400 into a fire signal or secret fire signal. An optical repeater 310 that determines whether it is a fire alarm signal and outputs at least one of a fire alarm signal, a preliminary alarm signal, and a failure signal, a relay circuit connected to the optical repeater 310 to control the output signal, and a preliminary alarm signal. Alternatively, it may be configured to include a buzzer 340 that emits light when the recovery button 320 is pressed.

The fire signal is a signal classified according to a preset signal detection method from the signal received through the input circuit in the P-type receiver 400, and the fire signal is transmitted to the output transmitter 500 through the first output 311 of the optical repeater 310. The preliminary alarm signal, which is not a fire signal but requires a preliminary alarm according to a preset fire detection method, causes the buzzer 340 to emit light through the second output 322, and the optical repeater 310 malfunctions. Alternatively, if the signal coming from the transmitter 550 is a failure signal, it may be output to the third output 313.

That is, the optical repeater 310 has a first output 311 that outputs a fire occurrence signal received from the P-type receiver 400, and a second output that outputs a recovery signal generated by pressing the preliminary alarm or recovery button 320. It may include 2 outputs 322 and a third output 313 that outputs a failure signal of the optical repeater 310 or a failure signal of the transmitter 550.

The recovery button 320 shown in FIG. 3 is a device that notifies that an emergency or abnormal situation has changed to a general normal situation and sets the system to its original state. It stops the output of preliminary alarm sounds or operation tests that inform non-fire information. It can perform the specified function. Additionally, it is possible to set various functions depending on the type of pressing of the recovery button 320. For example, when you press it for a long time, you can stop all output, when you press it briefly, you can stop the alarm sound output, and when you double-click it quickly, you can return the system to its original state. This example is just one example, and the operations and functions can be set in various modifications, and of course, they can be changed and set according to field requirements.

And, as shown in FIG. 3, the relay circuit includes a first relay circuit 331 connected to the first output 311 and a second relay circuit 333 connected to the third output 313. It can be configured as follows. A relay circuit is a circuit used to control electronic devices. It is a control circuit that performs a switch function to open or close a contact using the principle that current flows through a coil and becomes an electromagnet.

That is, since the preliminary alarm unit 300 of the fire alarm system according to an embodiment of the present invention receives the signal received from the P-type receiver 400 as a measured value such as current to an analog detector, the measured current detection signal is Depending on the classification method set and detected, whether the switch is opened or closed is determined through a relay circuit, so it can be controlled to distinguish between fire alarm signals, non-fire alarm or preliminary alarm signals, and fault signals, and output them by connecting to each output. . In addition, the preliminary alarm unit 300 can be integratedly managed and controlled by being installed in a fire alarm management room or disaster prevention room together with the P-type receiver 400, rather than in a transmitter box.

Figure 4 is a diagram schematically illustrating the internal wiring diagram of a transmitter box storing the output transmitter 500 of a fire alarm system applying an analog detector based on a P-type receiver 400 according to an embodiment of the present invention. Here, the transmitter box can accommodate the output transmitter 500 and the detection signal repeater 200, and the detection signal repeater 200 can be connected independently as a separate box, and the output transmitter 500 is, The output transmitter 500 may be configured to include a connection terminal 510, an alarm bell 520, an indicator light 530, and a transmitter.

More specifically, as shown in FIG. 4, the connection terminal 510 is an integrated terminal connected to the P-type receiver 400, a repeater, and the preliminary alarm unit 300, and the alarm bell 520 is a P-type receiver. It is an output device that sounds an alarm sound according to a fire alarm signal or preliminary alarm signal (non-fire alarm signal) received from (400) or the preliminary alarm unit 300, and the indicator light 530 is a warning light device that notifies the fire alarm and preliminary alarm status. It can be.

In addition, the transmitter 550 is a device that outputs a fire alarm or preliminary alarm through a signal received from the P-type receiver 400 or the preliminary alarm unit 300 through an output device, and transmits the fire occurrence signal to the P-type receiver 400. As a device for manually transmitting, it can be equipped with a four-wire system including a circuit (input) line, a common line, a response line, and a telephone line.

Therefore, the transmitter 550 may be equipped with a PUSH button switch, a response indicator light, and a telephone jack, and the operation method may be a method of transmitting only an ON/OFF contact signal by simply pressing the PUSH button switch. Here, the response line uses power line communication (PLC) technology, so it is possible to check the operation of the transmitter even without a response line, and the response indicator lamp can be turned on and kept on.

And, as shown in FIG. 4, the detection signal repeater 200 is a PLC repeater and is connected to the output transmitter 500 and the relay circuit 230, and is connected to the analog fire detector 100 by wiring. It may be provided with a PLC communication line 210 and an optical communication terminal 250 connected to an external setting change terminal 50 so that the setting value of the preset fire detection method can be changed. In this way, connecting the output transmitter 500 and the detection signal repeater 200 with the relay circuit 230 means that, if the signal received from the analog fire detector 100 is a fire signal, it is output directly without going through the receiver. This is to output a fire alarm sound through the transmitter 500.

Figure 5 shows a connection diagram of the detection signal repeater 200 of the fire alarm system applying an analog detector based on the P-type receiver 400 according to an embodiment of the present invention and the upper setting change terminal for determining the detection signal.

As shown in FIG. 5, the detection signal repeater 200 is connected to an analog fire detector through a PLC line, and the setting elements of the fire detection method can be changed by connecting an external setting change terminal 50. The detection signal repeater 200 and the external setting change terminal 50 may be connected through a communication conversion device (interface) 20.

And, the external setting change terminal 50, through the pre-installed setting change application UI, uses the preset fire detection method setting values, temperature and smoke concentration setting values for determining fire detection, and the detection signal repeater 200. You can adjust the buffering data judgment values within the system. You can change the standard temperature and smoke concentration values that are recognized as fire occurrences and the temperature and smoke concentration settings that can be judged as non-fire alarms or preliminary alarm signals.

The external setting change terminal 50 is a terminal that can be carried and moved to the field, such as a laptop or tablet PC, and configures fire element settings according to the fire detection method, detection signals, fire alarms, preliminary alarm information, failure signals, system control signals, etc. It may be a computing device including an arithmetic processing device capable of installing and executing a program capable of comprehensively changing settings and monitoring measured values of the fire analog detector in real time, and a storage device capable of storing the above-mentioned information.

Therefore, the fire alarm system applying an analog detector based on the P-type receiver 400 according to an embodiment of the present invention can be simply connected through an external setting change terminal 50 to provide integrated management such as system maintenance, repair, and data acquisition. It can be performed efficiently.
