As the number of people using these facilities increases due to the rapid progress of large-scale and high-rise buildings, when a disaster occurs, damage to not only property but also many people may occur. The modernization of firefighting equipment to prevent this is becoming an essential social foundation element.

For this purpose, buildings that meet certain conditions stipulated by law must have wireless communication auxiliary facilities installed. However, a much larger number of buildings under the legal conditions than those corresponding to the legal conditions are still left as a blind spot for firefighting communications. For example, in the case of the Jecheon fire accident in 2017, firefighters who entered the second basement floor and a large number of people waiting for rescue on the second floor due to a radio malfunction caused casualties. To prevent this, the power in the building is cut off and the installed communication facilities do not work properly. In this case, communication is paralyzed and there is a shadowed area where radio waves from the base station cannot be received, and it becomes difficult for field rioters to communicate with the outside. There are currently no adequate countermeasures for the fire-fighting communication problem caused by these building structures. Therefore, the importance of modernizing the equipment of firefighters in disasters, especially in suppression and rescue situations, is increasing. The failure of fire-fighting communication is attributed to the rapid loss of radio waves due to the complex indoor structure.

It is easy to eliminate the old shaded area.

and The LSU can send an emergency notification to the command post when abnormal motion is detected through real-time movement monitoring of the crew.

It shows the form of movement by the crew who is deployed and operated in the area, and Figure 1b shows the connection form of the radio terminal box connected and operated by connecting the PACS according to the present invention to the radio terminal box, and Figure 1c is by placing the PACS on the ground and underground of the building. It shows the fixed type of operation in operation.

Referring to Figure 1a, the first operating form is the PACS (100) carried when the disaster area changes to the shaded area 130 while carrying the PACS 100 according to the present invention in the building where the disaster occurred and carrying out suppression activities. It is an operation type that communicates with the PACS 100 and the LSU 105 by attaching the LSU 105 and moving to the shaded area while maintaining the communication connection state with the command post 120 by placing them in a nearby non-shaded area.

The third operation concept is a fixed structure, which can be operated while communicating with each other by installing the PACS (100-1) on the ground of the building and installing the PACS (100-2) in the basement.

2 is a block diagram showing the configuration of a PACS 100 of a portable wireless communication auxiliary equipment system interlocked with an active lifesaving device according to an embodiment of the present invention.

PACS 100 is a device that does not operate in a normal communication situation, but operates in a shadow area when a shadow area occurs due to a disaster, etc. Distribution (Front End Unit, 220), a slot change control unit 230 and a slot control transmission unit 240, and is made including a communication interface unit (250).

In particular, the low-loss RF coupling and distribution unit 220 is a core module for miniaturizing and lightening the portable wireless communication auxiliary equipment (PACS, 100).

3 is a block diagram showing the detailed configuration of the low-loss RF coupling distribution unit 220 of the portable wireless communication auxiliary equipment (PACS) interlocking with the active lifesaving device according to an embodiment of the present invention. 2 and 3, the low-loss RF coupling and distribution unit 220 enables signals to be coupled with low loss using a hybrid coupler and a channel filter (Ch Filter), and is made of a ferromagnetic material having a different resonance frequency. An elliptic circuit with excellent Skirt characteristics can be applied with the configured channel filters (Ch. Filters). For each characteristic of the channel filter (Ch. Filter), the other band suppression degree can maintain about 40 dB characteristics, and the low-loss RF coupling and distribution unit 220 is Input/output signals, for example, slot control signals, and input/output signals of DMR#1 and DMR#2 may operate at a fixed frequency by external control.

The low-loss RF coupling/distributing unit 220 distributes/combines three RFs (2 DMR terminals and DMR terminal #1 RF input/output) and maximizes the distance through 1.2dB_max low-loss signal coupling and distribution, adjacent to the Quad Hybrid coupler. It provides high-efficiency coupling performance by using a channel filter (Ch Filter) over 35dB of band suppression, and automatically changes the communication mode of the lifesaving device (LSU, 105) worn by the crew member through the LoRA wireless transmitter to respond to the emergency situation of the crew member. to enable radio wave propagation.

Referring to FIG. 3, the operation of the low-loss RF coupling/distributing unit 220 is described. When a signal is transmitted from the input/output terminal of the DMR terminal #2, the signal is transmitted through line A, and the signal is transmitted through the channel filter # at points c_1* and d_1*. 2 (Ch Filter#2) is fully reflected. The totally reflected signal is transmitted through the line B, and is fully reflected by the channel filter #1 (Ch Filter#1) even at points a_1* and b_1*. Accordingly, the totally reflected signal is emitted to the antenna rod through the line C. The above-described process operates in the same way in the case of the DMR terminal #1 and the slot-controlled RF input/output, and in the end, the signal is combined into the antenna with the minimum loss through the line C through the minimum loss.

The case of reception can also be described with the same structure, and each input/output signal operates in the same way. In the case of reception, a signal having the same frequency as that of the DMR terminal #2 is received through the line C connected to the antenna terminal. The corresponding signals are CH at points a_1* and b_1*. Full reflection by Filter#1. Totally reflected signal is CH at points c_1* and d_1*. Full reflection is performed by Filter #2. Therefore, the corresponding signal is transmitted to the DMR terminal #2 input through line A. The above process works the same even in the case of “DMR terminal #1 and slot control RF input/output”. As a result, each signal is divided into independent output terminals (DMR terminal #1, DMR terminal #2 and slot control RF input/output) with minimum loss through minimum loss.

DMR#1 and DMR#2 transmission/reception frequencies may have a frequency separation of about 4~10MHz, and if it is necessary to combine them with a low loss, it is usually necessary to manufacture a filter using a cavity resonator made of aluminum, but in this case, it may be bulky and heavy. In this case, in the case of a 1:3 splitter (Wilkinson type), a serious defect may occur in securing a communication radius due to a loss of about 5 dB. The low-loss RF coupling and distribution unit 220 of the PACS according to the present invention can overcome this problem.

And the slot change control unit 230 is a preset communication slot (Frequency) in order to allow the PACS 100 to communicate with the radio and the LSU 105 of the Daewon when the PACS 100 is turned on and starts to operate in the shaded area. or Time), a slot change control command (slot change control signal) is generated, and the slot change control command is transmitted to the slot control transmitter 240 .

When receiving the slot change control signal from the slot change control unit 230, the slot control transmitter 240 transmits the slot change control signal to the slot control receiver of the LSU 105 through the Front End Unit 220 and the antenna 210. do.

DMR (Digital Mobile Radio) radio uses digital encoding technology, eliminates system interference, enables clear voice calls even in noise, and improves voice quality in areas with weak signals. In addition, DMR radio can support two modes, analog and digital, in one radio.

When detected as a (data signal), a slot change control command is received and transmitted to the slot control unit 430 inside the LSU 105 .

The slot controller 430 receives a slot change command from the slot control receiver 420 and transmits a slot control signal to the DMR transmitter 440 informing that the communication slot to be transmitted to the outside has been changed.

When the DMR transmitter 440 receives the operator's status information from the gyro sensor 450, the operator's status information is transferred to the changed slot with reference to the slot change command signal transmitted by the slot control unit 430, and transmits the operator's status information to the antenna. It is transmitted to the PACS (100) through (410).

The state information acquisition unit 450 may include a sensor module that propagates an emergency situation through the DMR transmitter 440 inside the LSU when the value falls below the average exercise amount after detecting the activity amount of the field crew in real time.
