Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a block diagram of an apparatus for monitoring the occurrence of fire in an electrical facility using a spark detector according to an embodiment of the present invention. As shown in FIG. 1, the fire detection apparatuses 10A to 10N, wired / wireless transmitter 20, A conversion device 30 and a fire monitoring device 40.

The plurality of fire sensing apparatuses 10A-10N are installed in a disaster prevention area susceptible to fire in which an electric room, a power cable, or a switchboard is installed, each of which has a plurality of spark detectors 11 and a controller 12. [

The spark detector 11 detects a spark caused by an induction current, an overcurrent, an arc, or the like of an electric wire in an electric facility. Such a spark detector 11 is a type of ultraviolet sensor, which is a UV tron having a relatively narrow spectral sensitivity of 185 to 260 nm using the photoelectric effect of a metal and a gas multiplication effect, and a semiconductor photoelectric sensor which can not completely distinguish visible light. It is not necessary to use an optical visible cut filter.

That is, the spark detector 11 is a side-on type detector that detects a spark by using a photoelectric effect and a gas multiplication effect. The spark detector 11 has high sensitivity (10-step sensitivity) and wide field- Respectively. The spark detector 11 is not particularly limited. However, it is preferable that the spark detector 11 is installed at a position spaced apart from the monitored object by a predetermined distance, and is installed at a position where the monitored object can be directly seen. The spark detector 11 has a structure capable of adjusting the angle.

The controller 12 is connected to the spark detector 11 to determine whether a fire has occurred in the fire fighting area based on the output signal of the spark detector 11. When it is determined that a fire has occurred, the controller 12 sends a fire detection signal to the Zigbee or RS -485 communication network. At this time, the controller 12 may transmit the identification signal (ID) of the corresponding spark detector 11 to the fire detection signal.

The wired / wireless transmitter 20 is connected to the controller 12 and transmits a fire detection signal received therefrom through the RS-485 communication network.

On the other hand, the USB-serial communication converter 30 is connected to the wired / wireless transmitter through an RS-485 communication network and is connected to the fire monitoring device 40 via a USB communication module. Accordingly, the USB-serial communication conversion device 30 transmits a fire detection signal received through the RS-485 communication network through the USB communication module, or conversely, receives the signal received through the USB communication module via the RS-485 communication network And to convert it to be suitable for transmission.

The USB-serial communication conversion device 30 collects and transmits a fire detection signal output from each spark detector 11 of the fire sensing apparatuses 10A-10N. The USB-serial communication conversion device 30 can be configured to have three channels of alarm output, and a tower lamp or a horn can be provided to ensure quick judgment and visibility.

The fire monitoring device 40 monitors the occurrence of fire at the corresponding location in the disaster prevention area through the USB port for each independent group. That is, the fire monitoring device 40 detects the fire detection signal transmitted from the USB-serial communication conversion device 30 through the USB port and the identification code (ID) included in the fire detection signal, It recognizes that a fire has occurred in the disaster prevention area, displays a fire occurrence at the corresponding position on the screen, and generates an alarm. Accordingly, the administrator can recognize the location where a fire or a fire has occurred through the screen or the alarm, without paying much attention, and take necessary measures.

Meanwhile, FIG. 4 is a block diagram of an apparatus for monitoring the occurrence of fire in an electrical equipment using a non-contact type temperature sensor according to another embodiment of the present invention. As shown in FIG. 4, the apparatus includes a fire detection apparatus 110 and a fire monitoring apparatus 120 do.

The fire sensing apparatus 110 includes a plurality of spark detectors 111, a plurality of sensor nodes 112, and a sink node 113.

The fire detection device 110 is installed in an area to be monitored where a fire is likely to occur, such as an electric room, a power cable, or a power distribution panel, and a plurality of fire detection devices 110 may be installed as needed.

The spark detector 111 is installed in a surveillance zone or an object to be monitored in the surveillance target area, and has the same configuration as the spark detector 11 of FIG. 1 and performs the same function.

The plurality of sensor nodes 112 are installed in areas where fire is likely to occur, and detect the occurrence of fire at the corresponding locations. In general, a flame generated in an area such as an electric room, a power cable, or a switchboard generates ultraviolet rays of a specific wavelength band, and the sensor node 112 determines whether or not a fire has occurred based on ultraviolet rays of this particular wavelength band. Therefore, the sensor node 112 is judged whether or not the fire is generated based only on ultraviolet rays of a specific wavelength band generated from the spark, so that the fire in the target area is not affected by the external environment such as sunlight, mist, So that it can be accurately detected. The fire detection distance and installation distance of the sensor node 112 are not particularly limited and can be appropriately changed as needed.

The sensor node 112 generates fire data on the basis of the detected ultraviolet rays after detecting fire occurrence on the basis of the above-mentioned principle. The sensor node 112 is implemented to have a unique device identification number using RFID (Radio Frequency Identification) or USN (Ubiquitous Sensor Network) technology. Based on this technology, the fire data includes a location of a fire, The identification number of the sensed sensor node 112 and the identification number of the adjacent spark detector 111, and the like.

When the fire data is generated, the sensor node 112 transmits the fire data to the sink node 113 using the near field wireless communication method. The short-range wireless communication scheme is not particularly limited, and may include a zigbee scheme. The ZigBee scheme is a low data rate wireless communication technology as a representative technology of a wireless sensor network having advantages of low power, low cost, and ease of use. The plurality of sensor nodes 112 constitute a wireless mesh network so that some of the other sensor nodes in the fire sensing apparatus 110 including the sensor nodes which are difficult to continuously manage can not be discharged It is possible to transmit stable fire data to the sink node 113 through the routing between the remaining sensor nodes 112 that are normally operating.

The sink node 113 receives the fire data from the sensor nodes 112 and transmits the received fire data to the fire monitoring apparatus 120 through the remote wireless communication. As the long-distance wireless communication, a wireless local area network (LAN), a code division multiple access (CDMA), a dedicated line, or the like may be used.

The installation position of the sink node 113 is not particularly limited, but it is preferable that the sink node 113 is installed at a position relatively easy for the administrator to access and wirelessly communicate with the fire monitoring apparatus 120.

The sink node 113 may check whether the sensor nodes 112 of the carpenter are operating normally at predetermined time intervals and transmit the check result to the fire monitoring apparatus 120. [ The nodes 112 may not operate due to battery discharge or failure because they are difficult to maintain continuously. The sink node 113 confirms the sensor nodes 112 and transmits the same to the fire monitoring apparatus 120 so that the manager can take necessary measures.

Based on the fire data received from the sink node 113, the fire monitoring apparatus 120 recognizes that a fire has occurred at an arbitrary position in the corresponding disaster prevention zone, displays a fire occurrence at the corresponding position on the screen, And generates an alarm. Accordingly, the manager can recognize the occurrence of fire at the corresponding position and take necessary actions through the screen or the alarm without paying any special attention.

Although the preferred embodiments of the present invention have been described in detail above, it should be understood that the scope of the present invention is not limited thereto. These embodiments are also within the scope of the present invention.
