Fire fighting evacuation guidance system of the fire fighting telecommunications common use of the present invention is a detector for detecting a fire provided in the interior of a building, as shown in Figure 1, when a fire is detected, a fire detection message with a fire detection location A fire detector 100 to be transmitted to the evacuation management server 400 and a plurality of lines are arranged in a line along the ceiling of the corridor inside the building to transmit the temperature at each point of the corridor to the emergency evacuation management server 400 through power line communication. Power line communication temperature detector 200, and a controller for controlling the opening and closing of the emergency doors at the end of each corridor, while maintaining the emergency doors in a locked state and receiving an emergency door opening command from the emergency evacuation management server 400, emergency When receiving the fire detection message from the emergency door switch 300 and the fire detector 100 to open the requested emergency door to open the door, the temperature at each point of the corridor is determined to determine the temperature at the end of the corridor in the direction in which the temperature decreases. It may include an emergency evacuation management server 400 that transmits an emergency door opening command to open the emergency door to the emergency door switch 300. In addition, an evacuation guidance guidance light 500 may be further included. It will be described in detail below.

The fire detector 100 is a detector for detecting a fire provided in a plurality of buildings, and when a fire is detected, transmits a fire detection message to the emergency evacuation management server 400 together with the fire detection location. Therefore, the fire detector 100 may be implemented as various sensors, such as a flame detection sensor, a smoke detection sensor, and a temperature detection sensor, and various detectors including one or a combination of these may be included. The fire detectors 100 and 100 transmit a fire detection message to the emergency evacuation management server 400 together with the fire detection location and the unique ID of the fire detectors 100 and 100 when a fire is detected.

For reference, the communication method between the fire detector 100 and the emergency evacuation management server 400 includes Ethernet, Universal Serial Bus, IEEE 1394, serial communication, and parallel communication. A wired communication method such as may be used, and a wireless communication method such as Infrared Radiation, Bluetooth, Home RF (Radio Frequency), and Wireless LAN may also be used.

The power line communication temperature detector 200 is arranged in a line along the ceiling of the corridor inside the building, and performs a function of transmitting the temperature of each point of the corridor to the emergency evacuation management server 400 through the power line communication.

In the conventional temperature detector, as shown in FIG. 2, thermister, PT100 ohm, and thermo couple are commonly used, and a temperature transmitter is installed to display a temperature for a 4-20mA output to the temperature sensor. The temperature sensor is equipped with a 3-Wire cable to the transmitter, and a 4-20mA output displays the temperature value at the rear of the transmitter. I.O.modules are also used instead of transmitters. For example, if you install 100 temperature sensors, you will need 100 I/O cards or transmitters, and a 3-wire cable will require 300 strands. This method inevitably consumes a lot of cables, and also requires a large amount of I/O cards, is expensive to install, and is not suitable for long-distance use.

On the other hand, the temperature detector of the present invention uses the module that utilizes the power line communication technology so that hundreds of sensors can use the Two Wire Loop Power Line Communication using only two wires to obtain the address information and the temperature value in real time. Since it can be transmitted, it is possible to prevent a fire in advance when the temperature rises through monitoring. Therefore, if the Loop is configured as in the present invention, a maximum of 127 temperature sensors can be installed using one Loop card, and communication is possible up to a distance of up to 4 km. Not only is the cost of equipment reduced, air is shortened, but installation materials are significantly reduced.

To this end, the power line communication temperature detector 200 includes a 2-wire power line communication loop 210 and a temperature detection sensor 220 as shown in FIG. 3.

The 2-wire power line communication loop 210 includes a (+) line for transmitting an operating voltage and a current signal, and a (-) line arranged in parallel with the (+) line and serving as a reference voltage of the (+) line. do. Therefore, the temperature detection sensor 220 is connected in series to one communication loop.

The temperature detection sensor 220 is connected to a plurality of (+) and (-) lines of the 2-wire power line communication loop 210 to convert the temperature detection value into a current signal to convert the 2-wire power line communication loop 210 ) 210 and transmits the sensor ID to the loop card.

To this end, the temperature detection sensor 220 may include a detection sensor module and an ICT module. The detection sensor module is a module that detects a temperature value. Preferably, it can be implemented as an NTC thermistor that measures temperature. NTC thermistors are based on a continuous change in electrical resistance with a temperature coefficient, and have an inverse correlation coefficient with temperature. Due to the low power consumption, more sensors can be connected to the loop than other sensors. This is because (Intelligent Communication Technology) module can be used to implement various functions such as temperature correction and emergency recovery of the line in the event of a short circuit or short circuit.

The ICT (Intelligent Communication Technology) module is connected to the (+) line and (-) line of the 2-wire power line communication loop 210, can be assigned its own address, and sends its own address when transmitting the sensing output value. It transmits data including and enables signals to be sent even if an error occurs through the self-diagnosis function. Therefore, it is possible to record the exact location of accidents when an unusual event (fire, error, etc.) occurs by remembering the address.

In addition, the ICT module includes a CPU that converts a sensor output value of a decimal number including a sensing value measured by the detection sensor module into a binary current signal and transmits it through the ICT module. For reference, the current signal graph of the binary number is shown in 5, and the magnetic address, current status, measured temperature value, etc. can be converted into binary number and transmitted.

The emergency door switch 300 is a controller that controls opening and closing of emergency doors at the end of each corridor, and when an emergency door opening command is received from the emergency evacuation management server 400 while maintaining the emergency door in a locked state, the emergency door opening is performed. Perform control to open the requested emergency door. To this end, the emergency door switch 300 is a device capable of mechanically individually opening and closing emergency doors provided in each corridor by being installed in each emergency door by an operation program according to an external opening/closing request signal. The power supplied from the power supply is energized to control the forward movement of the clamp (not shown) by the induced current, and in an emergency, the main controllers cut off the power according to the emergency door opening command received from the emergency evacuation management server 400 to generate the induced current. It is blocked so that the emergency door is opened by the retraction of the clamp by the spring.

The emergency evacuation management server 400 has the same configuration as a conventional web server in hardware, and is implemented in various forms of languages such as C, C++, Java, Visual Basic, and Visual C in software. It contains a program module that functions. In addition, it can be implemented using web server programs provided in various ways according to operating systems such as DOS, Windows, Linux, Unix, and Macintosh on general server hardware. As representative examples, a website (website) used in a Windows environment, an Internet Information Server (IIS), and CERN, NCSA, and APPACH used in a Unix environment may be used.

When the emergency evacuation management server 400 receives a fire detection message from the fire detector 100, it determines the temperature of each point in the corridor to open the emergency door at the end of the corridor in the direction in which the temperature decreases. The door opening command is transmitted to the emergency door switch 300.

For example, as illustrated in FIG. 4, through the power line communication temperature detector 200, the temperature of each point in the corridor is grasped to open the emergency door at the end of the corridor in the direction in which the temperature decreases. This means that when the temperature decreases along the corridor in the event of a fire, it can be considered that it is far from the point where the fire occurred.

In addition, by grasping the temperature at each point of the corridor, an emergency door closing command for closing the emergency door at the end point of the corridor in the direction of increasing temperature is transmitted to the emergency door switch 300. This is because when the temperature rises along the corridor in the event of a fire, it can be considered to be close to the point where the fire occurred, so that the emergency door in the corresponding direction is closed to prevent smoke inflow from the point of fire.

When the fire detection message is received from the fire detector 100 as described above, the temperature at each point of the corridor is identified to open the emergency door at the end of the corridor in the direction in which the temperature decreases, or the end of the corridor in the direction in which the temperature increases. By closing the emergency door at the same time, it is possible to prevent the inflow of fire smoke and to evacuate quickly from the point of fire.

On the other hand, when the temperature detection sensor 220 connected in series to the power line loop is placed in each corridor, there is a problem in that installation cost is high. In consideration of these points, the fire emergency evacuation guidance system for the fire fighting telecommunications common use is a guide rail 10 arranged for each corridor line inside the building and a movable rail mounted on the guide rail 10 as shown in FIG. 5. The moving body 20 is provided. For reference, the guide rail 10 and the rail moving body 20 may be located on the wall surface of the hallway or on the ceiling surface of the hallway, but may be positioned inside the hallway ceiling so as not to be visible from the outside.

The plurality of temperature detection sensors 220 disposed in the same corridor line may be attached to the rail moving body 20 so that the rail moving body 20 is movable along the rail. Therefore, the rail moving body 20 is provided with a wireless communication unit, and can receive a movement control command from the emergency evacuation management server 400 to perform movement according to the movement control command.

In order to control the movement of the rail moving body 20, the emergency evacuation management server 400 and 400 moves the rail moving body 20 along the corridor line in the event of a fire to detect the temperature at each point of the corridor. .

For example, as shown in FIG. 6, while moving the rail moving body 20 along the corridor line, the temperature detection sensor 220 attached to the rail moving body 20 detects the temperature of the reprint point.

Therefore, even in a wide corridor, temperature can be detected while moving. For example, even in a 50m corridor section, the temperature of all sections can be detected while the rail moving body 20 having a size of 10m reciprocates 5 times. Of course, the temperature detection sensor 220 is connected to the 10m rail moving body 20 at 1m intervals in series with the power line communication loops 210 and 210, which in turn makes it possible to measure the temperature at 1m intervals.

On the other hand, in order to quickly evacuate in the event of a fire, the fire emergency evacuation guidance system for fire fighting telecommunications is provided with an evacuation guidance guidance light 500.

Therefore, the emergency evacuation management server 400, by grasping the temperature detected along the corridor line, it is possible to control to display the evacuation guide to the evacuation guide guidance light 500 to evacuate toward the corridor point in the direction of the low temperature do. Therefore, it is possible to detect the temperature of each corridor point at a low cost, thereby enabling efficient evacuation guidance.

Furthermore, the evacuation guide guidance light 500 may be attached to the rail moving body. Accordingly, the emergency evacuation management server 400 may perform evacuation guidance through the evacuation guide guidance lamp 500 attached to the rail moving body while moving the rail moving object along the corridor line in the event of a fire. Therefore, as the rail moving body moves in a direction in which the temperature is low, the evacuation guide guidance light 500 attached to the rail moving body also displays a guide toward the emergency door at the end of the corridor in the direction of low temperature to enable efficient evacuation.

For reference, the evacuation guidance guidance light 500 may display various evacuation guidance such as an arrow direction and evacuation phrases. Only the evacuation guidance guidance lamp 500 installed in the evacuation direction is turned on, and the remaining evacuation guidance guidance lights are turned off to guide the guidance.

The above-described embodiments in the description of the present invention are selected and presented as the most preferable examples to help those skilled in the art from among various practical examples, and the technical spirit of the present invention is not necessarily limited or limited by these embodiments only. , Various changes and modifications and equivalent other embodiments are possible without departing from the technical spirit of the present invention.
