1 and 2, the fire alarm system (FAS) may include a sensing system 100, a gateway (GW), and a server (SV).

The sensing system 100 may be a system that detects whether a fire has occurred. The sensing system 100 may include a plurality of sensing units SM. In FIG. 1, five sensing units SM are exemplarily illustrated, but are not limited thereto.

Each of the plurality of sensing units SM may detect whether a fire has occurred (S100). Each of the plurality of sensing units SM may transmit the first fire occurrence signal SG-1 to adjacent sensing units SM and/or the gateway GW (S200).

The first fire generation signal SG-1 may include a first signal SG-1a and a second signal SG-1b. The first signal SG-1a may be a signal generated by the sensing unit SM detecting whether a fire has occurred. The second signal SG-1b may be a signal amplified by the sensing unit SM.

As a method of transmitting the first fire occurrence signal SG-1, a radio frequency (RF) communication method may be used. The RF communication method may be a communication method of exchanging information by radiating radio frequencies. As a broadband communication method using frequency, it may have high stability due to little influence of climate and environment. The RF communication method may interwork voice or other additional functions and may have a high transmission speed. For example, the RF communication method may use frequencies in the 447 MHz to 924 MHz band. However, this is exemplary, and in one embodiment of the present invention, a communication method such as Ethernet, Wifi, LoRA, M2M, 3G, 4G, LTE, LTE-M, Bluetooth, or WiFi Direct may be used.

In one embodiment of the present invention, the RF communication method may include a LBT (Listen Before Transmission) communication method. This is a frequency selection method that selects another frequency again when it is determined that the selected frequency is being used by another system and is occupied. For example, a node intending to transmit may first listen to the medium, determine whether it is idle, and then send a backoff protocol prior to transmission. By dispersing data using the LBT communication method, collision between signals in the same band can be prevented.

The gateway GW may receive the first fire occurrence signal SG-1 from the plurality of sensing units SM. The gateway GW may convert the first fire occurrence signal SG-1 to the second fire occurrence signal SG-2. The gateway GW may transmit the second fire occurrence signal GS-2 to the server SV (S300).

As a method of transmitting the second fire occurrence signal SG-2, an Ethernet communication method may be used. The Ethernet communication method may be inexpensive to install and easy to maintain. However, this is exemplary, and in one embodiment of the present invention, a communication method such as Wifi, LoRA, M2M, 3G, 4G, LTE, LTE-M, Bluetooth, or WiFi Direct may be used.

The gateway GW may be connected to the Internet through the Ethernet. The gateway GW and the server SV may be connected to each other through the Internet. The distance between the gateway GW and the server SV is not limited if the Internet is connected. For example, the server SV may be configured in a space remote from the sensing system 100 and the gateway GW.

The gateway GW according to an embodiment of the present invention may be connected to the Internet through a Power Over Ethernet (POE). The gateway GW may be supplied with power through the Ethernet power supply. Therefore, a separate power supply may not be provided in the gateway GW. The gateway GW may communicate with the server SV through the Ethernet power supply. The gateway GW can be easily configured by the Ethernet power supply.

The server SV may transmit a fire alarm message to the plurality of parties 20 using the second fire occurrence signal SG-2 received from the gateway GW (S400).

The plurality of officials 20 may include, for example, a fire department, officials at a place where a fire has occurred, the National Safety Agency (or public institutions related to the public's safety), and the like. The plurality of parties 20 may receive a fire alarm message in the form of a text message, a video message, or a voice message through a landline phone, a smart phone, or other portable terminal.

3 is a flowchart illustrating a state checking method according to an embodiment of the present invention.

1 and 3, the gateway (GW) and the server (SV) may send and receive a status check signal (SCS) every predetermined time. The status check signal SCS may include a first check signal SCS-1 and a second check signal SCS-2.

The server SV may transmit the first check signal SCS-1 to the gateway GW. The gateway GW receiving the first check signal SCS-1 from the server SV may transmit the second check signal SCS-2 to the server SV. The server SV may receive the second check signal SCS-2 from the gateway GW and confirm that the gateway GW is properly connected.

After a predetermined time after the server SV receives the second check signal SCS-2 from the gateway GW, the server SV again sends the first check signal SCS-1 to the gateway GW. I can send it. Through this, the server SV can check the connection status with the gateway GW in real time.

When the server SV does not receive the second check signal SCS-2 from the gateway GW, the server SV may transmit a warning message to the plurality of parties 20. For example, the gateway GW may not transmit the second check signal SCS-2 to the server SV because power is not supplied or the Internet is not connected. In this case, even if a fire occurs, the gateway GW may not be able to transmit the second fire alarm signal SG-2 to the server SV. Therefore, the server SV may not notify the plurality of parties 20 that a fire has occurred. However, according to the present invention, the server SV and the gateway GW may exchange and send a status check signal SCS every predetermined time. In real time, it is possible to check the connection status between the server SV and the gateway GW, and to alert a plurality of parties 20 when an abnormality occurs in the connection status. The plurality of parties 20 may recognize that an abnormality has occurred in the connection state through the warning and take quick action.

The communication unit ATN may transmit the first fire occurrence signal SG-1 to other adjacent sensing units SM. When the sensing unit SM and the gateway GW are far from each other and it is difficult to directly transmit the first fire occurrence signal SG-1, the communication unit ATN generates the first fire to another adjacent sensing unit SM. By transmitting the signal SG-1, information transmission to the gateway GW can be stably performed. The communication unit ATN may receive the first fire occurrence signal SG-1 from another adjacent sensing unit SM.

The amplification unit AMP may amplify the first signal SG-1a and convert it to the second signal SG-1b.

The first battery TT1 may supply power to the sensor SS, the sensing memory MM, the amplifying unit AMP, and the communication unit ATN.

The use of power of the sensing unit SM can be minimized, and the sensing unit SM can be driven at low power. Accordingly, the first battery TT1 can stably supply power to the sensor SS, the sensing memory MM, the amplifying unit AMP, and the communication unit ATN for a long time.

When the first battery TT1 has insufficient power, the communication unit ATN may transmit a power shortage signal to the gateway GW.

6 is a flowchart illustrating a method of operating a communication unit according to an embodiment of the present invention.

4 and 6, the communication unit ATN may receive the first signal SG-1a (see FIG. 1) from another sensing unit SM. The received first signal (SG-1a, see FIG. 1) may be deteriorated in transmission rate and accuracy due to transmission distance and noise in the process of being transmitted from another adjacent sensing unit SM. However, the amplification unit AMP may amplify the first signal (SG-1a, see FIG. 1) in which the quality is deteriorated. The amplified first signal (SG-1a, see FIG. 1) may improve transmission rate and accuracy. The amplified first signal SG-1a (see FIG. 1) may be a second signal SG-1b (see FIG. 1). The communication unit ATN may transmit the second signal SG-1b (refer to FIG. 1) to the gateway GW. The communication unit ATN may transmit the second signal SG-1b (see FIG. 1) to at least one of the plurality of adjacent sensing units SM. The second signal SG-1b (refer to FIG. 1) may increase the accuracy, transmission rate, and transmission distance of information transmitted to the sensing unit SM and the gateway GW.

The second signal (SG-1b, see FIG. 1) according to an embodiment of the present invention may be transmitted to another adjacent sensing unit SM and amplified again in the amplifying unit AMP.
