Description

FIELD OF THE INVENTION [0001] The present invention relates to an analog current-

The present invention relates to an analog current sensing (ECP) address type fire detection system, and more particularly, to an analog current sensing type (ECP) type addressing system which tracks a difference in current flowing in an electric wire, FIELD OF THE INVENTION

Of course, rapid fire detection is important to minimize damage caused by fire.

The discovery of fire may be due to human operation such as the moment of the building manager, but there is a limit to continuously monitor each place of the building throughout the day.

Therefore, a fire detector automatically detects a physical phenomenon that is different from the daily life such as heat, smoke, flame, or the like caused by a fire using an automatic fire alarm system or a fire detection system, and transmits the detection signal to the receiver .

Generally, a fire detection system is a system for detecting and alerting a fire in a variety of spaces such as a single-family house, a multi-family house or accommodation, a business facility, or a large building.

This fire detection system is a system that monitors and controls fire alarms, fire extinguishers, and various facilities that display fire signals received from detectors and transmitters that detect fire, It is divided into contact type (P type) and frequency type (R type) depending on the transmission method.

FIG. 1 is a simplified view of a P-type fire detection system.

The P-type system has a receiver (2) and a detector (1) installed in each boundary area. In case of a fire, a switch which is a relay contact type of the detector 1) is closed to allow a current equal to or greater than a predetermined value to flow, or a relay contact type fire detection system.

The P-type system is connected by two signal lines that also serve as a power supply line to be supplied to the detector in the receiver. In the same signal line, a plurality of detectors for monitoring the same boundary zone are connected in parallel to form one line.

One of the two signal lines is commonly used in a plurality of lines, and the maximum number of lines that can be used in common to prevent the voltage drop of the common line is limited (generally 7 lines). Terminals (termination resistors) using resistors are generally connected to terminal ends of the respective circuits.

Detectors of P-type systems detect the change of current by resistance and inform the occurrence of fire, so they are simple and cheap, and they are widely used for single-type houses because they use general wiring.

However, in a P-type system, when one of the detectors on the same line is operated, the line current increases regardless of the type of the detector, so that it is not possible to identify which detector in the line has been operated. There is a problem that the accurate fire-generating device is not displayed and the wiring is required for each circuit, so that there is a problem that the number of transmission lines is large.

In addition, if a fault occurs in the equipment of the already installed system, it is necessary to check all the detectors of the whole area in order to repair it.

In order to solve such a problem, Korean Patent Registration No. 10-1322250 or No. 10-1242424 provides a system for notifying a fire place by changing the resistance value of a detector of a P type system.

However, even in this patent, since the receiver adopts the P-type receiver as it is, if the receiver fails, the entire system can not be stopped or the self-diagnosis function of the detector or the receiver can not be implemented.

2 is a simplified view of an R-type fire detection system.

The R-type receiver 3 and the detector 4 are connected directly through two signal lines which also serve as a power supply line or via a repeater.

Detectors connected through the repeater 5 can use general wiring like a P-type system, and the detectors directly connected to the signal line have a function of transmitting signals to the receiver.

Each of the detectors and the repeaters having the signal transmission function is called an analog address type because a unique number corresponding to the address of each device called an address (address) is set.

Several methods have been put to practical use in a transmission method. In general, a receiver transmits a paging signal specifying an address, and a corresponding device (detector or repeater) carries out transmission of information or execution of a control command.

The call is executed by sequentially changing the address, and if the return from the called device (detector or repeater) is stopped, it is judged that the signal line is disconnected.

In addition, even if a fire occurs, the fire detection signal of the detector is returned to the receiver directly or via a repeater upon a call from the receiver.

The receiver displays the location of the firing from the address value of the detector and operates the built-in sound device (main sound device). Unlike the zone window of the P-type system, the display of the ignition location is indicated by a digital value.

Therefore, when a fire is detected by using the R-type system, since the detector can be specified based on the address value, it is possible to grasp a more limited firing location as compared with the line unit of the P-type system, .

However, since a microcomputer (CPU) or a signal device for communication is required for each detector, the equipment price is high and data is lost due to noise due to noise generated in the surrounding electromagnetic field due to use of a communication line. There is a problem that the circuit of the detector is composed of electronic parts such as IC (IC) and is vulnerable to moisture and temperature.

In addition, when the renovation of the building and the expansion of the building are inevitable, if the pipeline is inevitably installed on the already installed system, the new wire is placed on the already installed system, and the entire R type system is paralyzed. And it was not possible to cope with such an emergency situation.

In order to solve such a problem, in Korean Patent Laid-Open Publication No. 2013-0027847, a system for self-diagnosing the state of the detector and judging a malfunction has been used. However, since it is not intended to solve the problem of each detector, Is expensive, and is vulnerable to electromagnetic fields.

Specific features and advantages of the present invention will be described in detail below with reference to the accompanying drawings. The detailed description of the functions and configurations of the present invention will be omitted if it is determined that the gist of the present invention may be unnecessarily blurred.

The present invention relates to a fire detection system for tracking a difference in electric current flowing through a wire to indicate a place where a fire is generated and is provided with an electric current purging (ECP) system operated in a unique manner different from existing P- ) Address type fire monitoring system.

In other words, the analog current sensing (ECP) address type fire monitoring system of the present invention is configured to have a different resistance value for each detector although ordinary wiring is used instead of a communication line unlike the conventional analog address type fire detection system, It is a fire detection system that can detect and protect the fire in the relevant area by generating a unique address of the detector and finding out the resistance value or unique address of each detector of the fire place when the fire occurs.

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

3 is a simplified diagram of an analog current-sensing (ECP) addressable fire detection system of the present invention.

The analogue current sensing (ECP) address type fire detection system of the present invention mainly includes a resistance address type fire detector 200 for notifying a fire place by a current value sensitive to a resistance value changed by fire occurrence, (ECP) for receiving the current value from the resistive address type fire detector or receiving the communication signal from the relay device and displaying the fire place, An addressable receiver 100 and an electrical wiring 400 for transmitting the current value to the repeater or the current sensing type addressed receiver in the resistive addressable fire detector.

In addition, a signal line 500 for transmitting a communication signal from the repeater 400 to the current-sensing type addressable receiver 100 uses a communication line unlike the electric wiring 400.

Also, the repeater 400 may be configured such that at least one repeater may be used according to the fire detection zone to allow a plurality of fire sensing zones to be performed in one current-sensing (ECP) addressable receiver 100.

Therefore, since the resistor-type fire detector 200 according to the present invention can transmit the current value to the repeater or can transmit the current value to the direct current sensitive (ECP) addressable receiver 100, Repeaters may not be necessary.

On the contrary, when the fire area is wide, a plurality of repeaters are installed, and an intermediate-level repeater that collectively transmits communication signals from the repeater to the receiver can be used. A fire signal due to the fire occurrence is transmitted from the detector to the repeater, The final fire signal may be transmitted from the intermediate relay to the receiver after being transmitted to the intermediate relay.

That is, depending on the area of the fire detection area, a repeater which does not use the repeater or connects the repeater and the receiver may be further used.

The resistive address type fire detector 200 detects the occurrence of a fire automatically by changing the resistance by using heat, smoke, or a flame generated by a fire, and notifies the location of the fire to a repeater or a receiver.

Since the resistive address type fire detector 200 of the present invention is configured to detect the occurrence of fire according to the change of the resistance value, the resistive address type fire detector 200 may be configured such that the resistance value changes when heat, smoke or flame is separately detected, If the heat and flame or smoke and flame are detected in combination, the resistance value may be changed.

FIG. 4 is a circuit diagram of a resistive address type fire detector 200 included in the current sensing type (ECP) address type fire detector of the present invention.

The resistive address type fire detector 200 includes a contact type switch 210 electrically connected to the electric wiring 400, a dip (DIP) switch 220 connected to the contact type switch 210, and a plurality of resistors 230 ).

The contact type switch 210 is short-circuited by heat, smoke, or a flame generated when a fire occurs, and is connected to the resistance of the sensor.

In other words, when a fire occurs according to Equation 1 below, the resistor 230 is connected to the resistor-type fire detector 200, so that current flows through the resistor-type fire detector 200 to detect the occurrence of fire.

V = IR - (Equation 1)

When the resistive address type fire detector 200 according to the present invention is set to have a specific resistance value, the resistive address type fire detector 200 is connected to the electric wiring 400 in parallel, And the value of the current I changes according to each intrinsic resistance value, so that the fire detector detecting the fire can be grasped by calculating the changed current I value.

As a method of realizing a unique resistance value for each resistance-type fire detector 200, a resistance having different resistances (for example, 10 ?, 20 ?, 30 ?, etc.) for each detector may be directly installed or the dial may be converted You will be able to give different resistances by using variable resistors which can give different resistances.

However, these methods have a very narrow range in which different resistance values can be given to the detectors. For example, in the case of a variable resistor, a different resistance value may be assigned to each detector by the number of units displayed on the dial. Normally, the number of units is not more than 20.

Thus, it is desirable to use dip switches with multiple ON / OFF switches to address the detectors with different resistance values.

In general, dip switches are implemented in the form of an integrated circuit package. However, the integrated circuit type package is often temperature or humidity sensitive and causes malfunctions. Off function, it is preferable that the switch is composed of a switch having a plurality of relay contacts.

For example, if there are 5 relay contacts of the dip switch, the resistance value can be given differently to the 5th power (32) of the 2 sensors. If the number of the relay contacts of the dip switch is increased to 6, 64), by increasing the number of relay contacts of the dip switch to 7, you can assign different resistance values to 2 7th (128) detectors. (It is assumed that the number of resistive elements connected to the dip switch is equal to or greater than the number of relay contacts of the dip switch.)

That is, when the dip switch of the present invention is used, it is possible to constitute a large resistive address type fire detector to have a uniform resistivity value, and its operation or use is very easy.

At the end of the plurality of resistive addressable fire detectors in the repeater, a termination resistor or a termination resistance detector (not shown) is provided for circuit conduction testing.

The address setting method of the resistance address type fire detector 200 will now be described in detail.

If there is no fire, the resistance value of the resistor-type fire detector 200 is either the terminal resistance or the terminal resistance of the sensor or resistor connected to the repeater when viewed from the repeater or the receiver. Therefore, the current value at this time is registered as the initial value, When the contact type switch 210 of the resistive address type fire detector is short-circuited, the current value is changed in response to the resistivity value of the short-circuited first resistive address type fire detector. Specifies the unique address of the fire detector.

Similarly, when the contact type switch 210 of the second resistor type address type fire detector is short-circuited, the changed current value is stored in response to the resistivity value of the short circuit of the second resistor type resistive type fire detector. Specifies the unique address of the second resistive address type fire detector.

In this way, by shorting the contact type switch of each resistive address type fire detector, it is possible to specify the unique address of all resistance type address type fire detectors.

Therefore, if a resistive address type fire detector with a unique address is used, each resistive address type fire detector can be individually recognized by the receiver. In case of a fire, a unique address of the corresponding detector Or place may be displayed.

In addition, when a fire occurs simultaneously in a plurality of places, a contact switch of a resistive address type fire detector having a resistivity value is simultaneously short-circuited simultaneously, so that a control unit (CPU) It is possible to calculate the intrinsic resistance value and the current value transmitted to the repeater so as to grasp the location of the fire or the fire detector which occurs simultaneously.

In the case of a fire, the contact switches of the resistive address type fire detectors having respective resistances are sequentially short-circuited. Therefore, the current values are sequentially changed. Direction can be easily grasped.

In addition, when the resistive address type fire detector is used, the contact switch of the resistive address type fire detector is short-circuited from time to time, so that it is possible to determine whether the detector itself is faulty.

FIG. 5 is a simplified circuit diagram of a repeater included in the analog current sensing (ECP) address type fire detection system of the present invention.

The repeater receives the DC voltage from the output terminal of the current sensing type (ECP) address receiver through the power input terminal 310, and the DC voltage is usually 24V, but the voltage value is only an example. But is not limited thereto.

The voltage value input from the power input terminal 310 is lowered to a voltage for use in a resistive address type fire detector connected to the repeater through the voltage converter 320. [ The voltage normally used for resistive address type fire detectors is typically 5V, but these voltage values are illustrative only and not limiting in the present invention.

When the voltage value supplied from the power input terminal 320 is a digital value, the voltage converter 320 converts the digital signal into a digital / analog (D / A) converter Function.

The output terminal 3100 of the repeater is connected to the resistance address type fire detector through the electric wiring 400 and transmits the current value transmitted from the resistive address type fire detector to the current sensor 380 through the electric wiring.

The output terminal can also be connected to resistive address type fire extinguisher, address type fire hydrant, hydrant low water level signal, sprinkler, alarm device and fire shutter operation device.

The current sensor 380 measures the current value transmitted from the resistive address type fire detector, and the measured current value is amplified through an amplifier 390 and then converted to a digital value or a discrete value And is transmitted to the repeater control unit 340.

The repeater control unit 340 changes the digital address transmitted through the A / D converter and the unique address of the repeater designated by the ID setter 370 for setting the repeater unique address to a relay communication unit 330 do.

The repeater control unit 340 may also determine whether the measured current value is maintained or not, and may determine whether the fire has actually occurred or a malfunction of the resistance address type fire detector. If the voltage converted by the voltage converter 320 exceeds the threshold value It is possible to control the short-circuit switch 3200 to shut off the power supply to the resistive address type fire detector.

 In addition, the output current limiting device 350 performs a function of limiting the output current to protect the resistor-type fire detector by using a limiter when a voltage value converted by the voltage converter is equal to or higher than a threshold or when a voltage such as an overvoltage is generated.

 The relay communication unit 330 transmits a communication signal to a current-sensitive type (ECP) addressed receiver to notify that an arbitrary resistance address type fire detector has generated a fire.

In addition, the repeater can protect the zone by the independent control function of the relay control unit even if the function of the current-sensing type (ECP) addressed receiver is stopped, and the power supply is blocked in the current- It is possible to further include a power storage device so as to perform the disaster prevention function.

6 is a simplified circuit diagram of a current-responsive addressable receiver included in an analog current-sensing (ECP) addressed fire detection system of the present invention.

The ECP addressable receiver receives the AC power from the power supply 110 and converts it into a DC power that is output from the voltage converter 130 to the repeater.

In addition, the voltage converter 130 may also function as a digital / analog (D / A) converter to provide a voltage value supplied to the repeater as an analog signal.

The output terminal 120 is connected to the repeater 300 to supply DC power to the repeater or to transmit the communication signal transmitted from the repeater to the receiving communication unit 140.

The reception communication unit 140 receives the communication signal from the relay or receives the current value from the resistance address type fire detector and transmits the received current value to the control unit 160. The control unit 160 analyzes the received communication signal or current value, And displays a fire place on the display unit 150 such as an LCD or a monitor.

The ECP addressable receiver may further include a power storage device (not shown) or a non-power saving device 170 (to be described later) when the power supply from the power supply part 110 is interrupted (RTC), or to record fire information such as a fire time, a fire place, a fire range, or a data logger or a data storage device so that the manager can easily grasp the fire time You may.

7 is an exemplary view of a display unit of a current-sensing type (ECP) addressable receiver included in an analog current sensing (ECP) address type fire detection system of the present invention.

The display unit 150 includes an operation state display unit 151 for displaying a fire occurrence indication and an operation state of a current sensitive type (ECP) address type receiver, and an opening / closing device for opening and closing a door of a current sensitive type (ECP) A power status display unit 154 for displaying the power type and power status of the individual interlocking / activating unit 153 and the current sensing type (ECP) address receiver for setting the interlocking and individual start of the facility, A main operation unit 156 for performing a state control, an interlock control, a receiver test and a function code setting operation of a fire place display unit 155 and a current sensitive type (ECP) addressable receiver, and an acoustical unit Device 157 may be included.

In particular, the fire place display unit may display an LED corresponding to each resistance type fire detector by lighting it, or may be constituted by a monitor for displaying the fire occurrence area in Arabic numerals or Hangul. This is merely an example of a fire place indication, and the fire place indication part of the present invention is not limited to LED or monitor.

In addition, the current-sensing (ECP) addressable receiver of the present invention further includes a non-recycling device 157 to prevent non-fire alarms. If the current value transmitted from the resistive address type fire detector is longer than a predetermined time (5 <t <60 sec), the non-fire alarm device judges that the fire has occurred. If the current value is less than the predetermined time, If the number of erroneous operations of the fire detector exceeds a certain number of times, it is notified to the manager to prevent an accident that the fire detector is not detected due to the malfunction of the resistance address type fire detector.

In addition, the current-sensitive (ECP) addressable receiver of the present invention may be used in combination with a gas leakage alarm facility by a person having ordinary skill in the art.

The electrical wiring 400 from the resistor-type fire detector to the repeater of the present invention is preferably installed according to refractory wiring or heat resistance wiring with normal wiring and may be installed with 600V vinyl insulation wire between detectors.

Also, in the absence of a repeater, the electrical wiring 400 from the resistive address type fire detector to the current sensing type addressable receiver (ECP) is preferably installed in accordance with refractory or heat resistant wiring with normal wiring.

In addition, a wiring line 500 from a repeater to an intermediate-level repeater or repeater to an electric current-sensitive (ECP) addressed receiver uses a communication line capable of transmitting a communication signal. In order to reduce noise due to impedance or a surrounding electromagnetic field, .

FIG. 8 is a block diagram of a resistive address type fire detector 600 included in the analog current sensing (ECP) address type fire detection system of the present invention.

The resistive address type fire detector 600 is configured to have a unique address of the transmitter by a dip (DIP) switch or a directly set resistivity value, like the resistive address type fire detector 200.

Accordingly, when the push button is operated by a person who finds a fire, the resistive address type fire detector 600 performs a role of a contact switch, so that the resistance value of the transmitter is connected to that of the resistive address type fire detector 200 The current value is changed so that the occurrence of the fire and the position of the transmitter are notified to the repeater or the current-sensing type addressable receiver.

The transmitter may be divided into a transmitter capable of communicating with the receiver and a transmitter unable to communicate with the receiver depending on the type of the transmitter. The present invention includes all transmitters capable of indicating the position of the transmitter by a specific resistance.

The resistive address type fire detector 600 is configured to control the push switch 605 and the push switch 605 to send a fire signal to a current sensitive type (ECP) addressed receiver when a fire occurs, And a response light 603 which is turned on to allow the operator to confirm whether the signal transmitted by the operation of the resistive address type fire detector 600 is delivered to the current sensing type addressable receiver (ECP) A telephone jack 602 for inserting a mobile communication terminal for interconnection with an over current sensitive type (ECP) addressable receiver, and a location indicator 601 for indicating the location of the resistance address type fire signal transmitter 600 .

The alarm device of the present invention may be configured such that when the resistive address type fire detector 200 or the resistive address type fire signal transmitter 600 is operated to receive a signal of the current sensitive type addressed type receiver, And informs people of the occurrence of the fire.

Such a warning device is divided into an acoustic alarm device for alarming people by sound and a visual alarm device for alarming by the time of day, and a sound alarm 701 or a siren 702 is widely used as an acoustic alarm device. A xenon lamp 703 using red light or flash light is widely used.

10 is a perspective view of an address type fire hydrant included in the analog current-sensing type (ECP) address type fire detection system of the present invention.

As in the case of the resistive fire type fire detector 200, the address type fire hydrant is configured to have a resistivity value by connecting a setting of a dip (DIP) switch or a direct resistance.

In addition, if the opening / closing signal by the opening and closing of the fire extinguisher box or the use of the fire extinguishing tool is configured similar to the contact switch of the resistance address type fire detector and the fire extinguisher is opened or the fire extinguishing tool is used, This allows the repeater to know which digits are open in the current-sensing (ECP) addressed receiver and which digesters are being used.

The address type fire hydrant according to the present invention includes a fire extinguisher box cover 801 for opening and closing a fire extinguisher box, a fire extinguisher box position indicator 803 for indicating the position of the fire extinguisher box, and a beacon 802 for alerting sound when a fire occurs do.

11 is a conceptual diagram of remote control using an analog current-sensing (ECP) address type fire detection system of the present invention.

The ECP addressable fire detection system of the present invention further includes a mobile communication terminal capable of receiving a radio signal for fire occurrence from a current sensitive type (ECP) addressed receiver and monitoring the fire remotely . The mobile communication terminal refers to a terminal capable of remotely controlling a current sensing type (ECP) address receiver by incorporating a CPU in a mobile communication terminal such as a PDA, a tablet PC, and a smart phone.

When a communication signal for fire is received from a repeater, the ECP addressed receiver informs the pre-registered mobile communication terminal of the occurrence of the fire including the location of the fire, And the status of the receiver or the repeater can be monitored by inputting only the ID and password using the smartphone web site or application.

Accordingly, the analogue current sensing (ECP) address type fire detection system of the present invention can detect a real-time fire situation remotely without any restriction on time and place by using a mobile communication terminal, and can solve a fire situation quickly and accurately .

In addition, the analog current sensing (ECP) address type fire detection system of the present invention manages real-time information items and alarms in real time, transmits the information items and alarms to the pre-registered users, And a fire control center for minimizing the risk of fire.

FIG. 12 is a operational diagram illustrating the operation of the resistive address type fire detector and the current-sensing type addressable receiver of the present invention.

(ECP) addressed type receiver (ECP) when heat or smoke is applied to the repeater 1 (J1) connected to the repeater 1 (J1) and the repeater 2 (J2) connected to the repeater 2 As shown in FIG.

As shown in the operation diagram, since the resistance value of each resistance type address detector is different according to the resistivity value, the current value due to the short circuit or fire occurrence of the contact type switch is measured differently according to the sensor, The receiver will be able to identify the exact location of the fire.

Figure 13 is an illustration of a fire system connected to an analog current sensing (ECP) addressable fire detection system of the present invention.

In the present embodiment, the repeater is omitted in order to increase the concentration of the description. If the fire area is wide, a repeater can be placed between the receiver and each fire facility. The current sensing type fire detection system according to the present invention has a resistive address type fire detector, an address type fire (indoor fire hydrant), a resistance type address transmitter, a fire door, etc., The opening and closing of the fire extinguisher and the opening of the fire door can be monitored by the current sensitive type (ECP) address receiver.

In particular, the analog current-sensing (ECP) address type fire detection system according to the present invention tracks the difference in electric current flowing through an electrical wire in the event of a fire, so there is no need for a communication line. Since the direction of progress or increase / decrease of fire can be tracked, it is possible to trace the fire and suppress the fire early.

In addition, it is possible to address the fires by border zone, so that it is possible to concentrate the overall facilities for fire such as fire detectors, fire extinguishers, and fire hydrants in one control center, thereby operating the system with fewer personnel.

Therefore, if the detector is replaced with a resistive addressable type fire detector in the existing P type fire system, the electric wiring used in the P type fire system can be used as it is and the fire place can be grasped.

In addition, since the conventional R type fire system or the R type analog address type fire detection system can use the communication line from the receiver and the receiver to the receiver as it is, an inexpensive resistor type fire detector can be used.

That is, the analog current sensing (ECP) address type fire detection system according to the present invention can be used as it is compatible with the components used in the P type fire system, the R type fire system, or the R type analog address type fire system.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is clearly understood that the same is by way of illustration and example only and is not to be taken as a limitation of the scope of the present invention. Or modify it. The scope of the invention should, therefore, be construed in light of the claims set forth to cover many of such variations.
