Description

{Fire warning system comprising early fire warning and evacuation for multi use facility}

The present invention relates to a fire alarm system for fire early warning and evacuation systems in multi-dense facilities. More specifically, it relays fire information by including a fire alarm terminal in the fire alarm system, and the fire alarm terminal is a fire information receiver (e.g. For example, by linking with a P-type receiver) to receive signal data by wire from multiple P-type receivers and transmitting it to the management server, a specific receiving module according to these protocols is installed from the P-type receiver that can use different communication protocols. Rather than transmitting signal data wirelessly directly to the management server, the fire alarm terminal receives the collected fire information data in batches and receives it from the management server based on a single protocol, thereby ensuring the convenience of transmitting and receiving information.

The risk of fire exists in everyday life. There is a lot of use of flammable building materials, and logistics warehouses are becoming larger and more complex due to the revitalization of online markets, so it can be said that they are exposed to a disaster environment that could lead to a serious accident.

However, despite these risks, there are many cases in which the fire extinguishing equipment itself is stopped for fear of malfunction, and as a result, the fire extinguishing equipment does not operate even when a fire occurs, leading to a large fire.

For example, in the Dongtan Metapolis fire accident, 4 people died and 52 casualties occurred, and in this case, the fire extinguishing equipment did not work properly. In particular, out of a total of 2,345 days since opening in September 2010, district alarms sounding sirens throughout the mall were used for 2,336 days (99.6%), fire shutters were used for 2,179 days (92.9%), air supply fans were used for 2,118 days (90.31%), and exhaust fans were used for 2,033 days (90.31%). 86.69%), it was turned off all the time, and it was found to be turned on briefly only on special days such as fire inspection day. In addition, it is common in many buildings to shut down the equipment itself to prevent malfunctions.

Accordingly, there is a need for a system that can check the management status of firefighting facilities installed within a specific firefighting object, but such a system is currently absent and only checks operation during the six-month cycle of operational function inspection. Therefore, it can be said that a system that allows safety managers or local fire departments to check the status of firefighting facilities even during normal times is necessary. In particular, when simply adding a detector, there is a problem that installation of additional detectors requires a large amount of space and cost, so adding detectors is considered undesirable.

In addition, the development of IT-based technologies related to disasters and fires is currently underway, but they are only applied to large or expensive systems. In particular, P-type receivers mainly installed in old, multi-dense facilities are only linked to breaking news and are also used by each company. There are no modules commonly used for each P-type receiver. In other words, the communication protocol for each manufacturer of P-type receivers is different, and there is a problem in that it is impossible to obtain signal data from each P-type receiver through communication.

Republic of Korea Patent Publication No. 2004-0039513 (May 12, 2004)

The present invention was created to solve the problems of the prior art described above. The present invention collects signal data (fire signal, fire extinguishing equipment operation signal) from a P-type receiver as a wired contact signal in a module and transmits it wirelessly, thereby Even if the communication protocols of the P-type receivers are different, signal data can be obtained from the P-type receiver in a wired manner regardless of this, and it is possible for building managers or fire departments in charge to check such signal data through an Ethernet network, etc. The purpose is to provide a fire warning system for early warning and evacuation systems for fires in multi-dense facilities.

It is preferable that the P-type receivers use different communication protocols in part or in whole.

The fire alarm terminal includes an input module for receiving signal data including fire information from the P-type receiver; A conversion module for converting signal data received from the input module into fire information or receiver status information; a calculation module that performs a signal data calculation process to determine a current fire-related state or a firefighting equipment operation state from the converted signal data; and a transmission module for converting the calculated signal data into a protocol for transmitting fire information and transmitting the converted signal data to the outside.

The fire alarm terminal preferably includes a port for transmitting PS/TS signals of fire extinguishing equipment, switch status signals, and fire signals, and a spare port.

It is preferable that signal data transmission from the fire alarm terminal to the management server is wireless transmission using a fixed IP.

A fire detector is a device that can automatically detect the occurrence of a fire and send an alarm to a receiver. At this time, there are five types of receivers: P-type, R-type, M-type, GP-type, and GR-type. Among them, the P-type receiver 100 transmits the signal transmitted from the detector or transmitter directly or through a repeater to a common signal. It is a receiver that receives information and generates an alarm. A common signal line in a certain monitoring area is connected from the detector and transmitter to the P-type receiver (100). If the number of surveillance areas is large, a large number of signal lines are required, but because the wiring is simple and inexpensive, it is widely used in small buildings. Typically, the P-type receiver 100 transmits signals wirelessly, and the signal transmission protocol may vary depending on specifications. At this time, when transmitting a signal containing fire data from the P-type receiver 100 to the management server 300, a receiving module must be individually included to correspond to the signal transmission protocol compatible with each P-type receiver 100. There is a problem that the size of the device increases. Accordingly, in the present invention, a fire alarm terminal 200 is configured between the P-type receiver 100 and the management server 300, and the fire alarm terminal 200 and the P-type receiver 100 are connected by wire, and the fire alarm It is characterized by transmitting fire-related data as a signal from the terminal 200 to the management server 300 through wireless transmission. In other words, the fire alarm terminal 200 can collectively receive fire-related signal data from various P-type receivers 100 and transmit the collected signal data to the management server 300 based on a fixed IP and a single protocol, thereby generating the signal. The scale of equipment for transmitting data can be reduced and the configuration can be simplified, and signal data transmission has the advantage of being very convenient.

The present invention relates to a fire detector; A P-type receiver 100 that receives a fire signal from the fire detector; It includes a fire alarm terminal (200) that is connected to the P-type receiver (100) by wire and transmits signal data transmitted from the P-type receiver (100) to the management server (300) by wireless communication. The fire alarm terminal 200 is connected to a plurality of P-type receivers 100 and collects signal data from each P-type receiver 100. The collected signal data is divided into collection status and signal data for each individual receiver and is sent to the management server. Provides a fire alarm system for fire early warning and evacuation systems in multi-dense facilities, characterized by transmission to (300).

Here, the fire detector is a smoke detector and is a standalone alarm type detector, and it is desirable to transmit fire signal data to the fire alarm terminal 200 in a wireless format by applying a firefighting wireless communication frequency of, for example, 447 MHz. Here, the standalone alarm type detector is a detector that independently performs fire detection and alarm regardless of the receiver, and when the system according to the present invention is installed, the standalone alarm type detector can be additionally linked, thereby adding compatibility. That is, the present invention uses a stand-alone alarm detector separately from the fire alarm terminal 200 receiving signal data from the P-type receiver 100, so that signal data can be transmitted to the fire alarm terminal through the communication module of the stand-alone alarm detector. You can.

The P-type receivers 100 typically operate in part or all of different communication protocols. When connected to a plurality of P-type receivers 100 using the same communication protocol, wireless connection with the fire alarm terminal 200 will be possible, but in reality, this possibility is very small. In other words, it is more likely that the plurality of P-type receivers 100 are each based on different protocols in wireless transmission. Therefore, introduction of the present invention has advantages in this environment.

The fire alarm terminal 200 includes an input module 210 for receiving signal data including fire information from the P-type receiver 100; A conversion module 220 for converting signal data received from the input module 210 into fire information or receiver status information; An operation module 230 that performs a signal data calculation process to determine the current fire-related state or the operation state of firefighting equipment from the converted signal data; and a transmission module 240 for converting the calculated signal data into a protocol for transmitting fire information and transmitting the converted signal data to the outside.

The input module 210 is connected to the external P-type receiver 100 by wire to input signal data. It can also be connected to a single alarm type detector, but the single alarm type detector is wirelessly connected to the fire alarm terminal (200). In other words, the fire alarm terminal 200 is connected to the P-type receiver 100 by wire and to the stand-alone alarm detector by wireless, and serves as a bridge to transmit signals to the management server 300. When the signal data is converted into information by the conversion module 220, calculation is performed by the calculation module 230 to check its status, for example, whether the current firefighting equipment is operating normally or abnormally. . When the calculation is performed and the current fire status or firefighting equipment operation status is confirmed, the information is transmitted to the management server 300, and the activities of the fire alarm terminal 200 are performed in real time.

The fire alarm terminal 200 transmits fire signals including PS/TS signals of fire extinguishing equipment, status signals such as operation, stop, and termination of the switch included in the P-type receiver 100, and whether or not a fire has occurred. May include ports and spare ports. Using this port, the corresponding signal is converted to the management server 300 and quickly transmitted. Before that, the P-type detector receives operation signals including manual, automatic, and stop from the fire extinguishing equipment, displays them, and transmits them to the fire alarm terminal 200.

The signal data transmission from the fire alarm terminal 200 to the management server 300 is preferably wireless transmission using a fixed IP. The use of fixed IP was implemented by setting detailed standards for the installation of integrated surveillance facilities as NFSC 607 (fire safety standards for underground districts) was announced on July 16, 2020. Therefore, by using it as the basis (draft) of detailed standards related to integrated monitoring facilities such as fire stations and management offices that can include the management server 300 as an integrated monitoring facility for fire, the effectiveness and scalability of the standard regulations of the integrated monitoring facility are confirmed. can be secured simultaneously.

In addition, the present invention is a method of operating the above-described system, which is performed by the fire alarm terminal 200, and includes the steps of the P-type receiver 100 obtaining signal data from the fire detector (S410); Converting the obtained signal data into fire information and receiver status information (S420); Deriving result data by calculating the converted signal data (S430); and a step (S440) of transmitting the result data to the management server 300 in accordance with a communication protocol. .

This embodiment as described above is presented to explain the present invention in more detail, and it is obvious that the scope of the patent claims is not to be interpreted as limited by this embodiment.
