The supplied power is supplied to the wall port (outlet) of each room through the building's distribution board. Accordingly, the user can use the power by directly connecting the power line of the electric device to the wall port or by connecting it to the wall port through a multi-tap. do.

In the process of using such power, power supply parts such as power lines, power lines, and distribution boards are defective or deteriorated and thus not insulated, or fires occur due to the user's use of power exceeding the rated power. Due to the serious damage to human life and property due to such fires, concerns about fires are increasing day by day.

In order to detect such a fire, various devices using an existing communication network have been developed. However, when a fire occurs and the communication network does not operate, the device for detecting the fire also becomes inoperable.

1 is a diagram schematically showing the configuration of a fire detection system 1 according to an embodiment of the present invention.

Referring to FIG. 1 , the power supplied to the building from the outside is supplied to the wall ports 210 and 220 (outlets) of each room through the intelligent distribution board 10 in the building, and accordingly, the user uses the multi-tap ports 311 to 314 and 321 324) through the wall ports 210 and 220, or by directly connecting the power lines of the electric devices 410 to 450 to the wall ports 210 and 220, although not shown in FIG. do.

The IoT nodes 21 , 22 , 31_1 , 31_3 , 31_4 , 32_1 , and 32_3 are installed in the wall ports 210 , 220 or the multi-tap ports 311 , 313 , 314 , 321 , 323 . In FIG. 1 , IoT nodes 21 and 22 are installed in wall ports 210 and 220 , respectively, and IoT nodes 31_1 , 31_3 , 31_4 , 32_1 , 32_3 are multi-tap ports 311 , 313 , 314 , 321 , 323 . ), and the electric devices 410 to 450 are respectively connected to the IoT nodes 31_1, 31_3, 31_4, 32_1, and 32_3.

Referring to FIG. 2 , when data to be transmitted (IoT node data) is “10011010”, it is modulated into a high-frequency signal by FSK to obtain a waveform as shown in the lower left of FIG. 2 . When this, for example, a waveform of an AC power of 60 Hz is used as a carrier, a signal as shown on the right side of FIG. 2 is transmitted.

This method of power line communication has disadvantages such as high load interference due to impedance mismatch, and a lot of noise because the power signal and the data signal are not separated.
