The drone 100 is equipped with a camera unit 120 composed of a thermal imaging camera and a photographing camera and is provided with a thermal image and a general image for coal stored in a heating element, .

Since the drone 100 is not a fixed system but a mobile system, the necessity of maintenance and repair is drastically reduced as compared with the conventional fixed type, and since it is possible to monitor the details of the coal store facility through flying, It is possible to secure the security of low profitability from the risk.

The flight mode of the drone 100 is classified into an "automatic flight mode" and a "manual flight mode", and the user can select the flight mode of the drone 100 through the operation of the controller 200.

If the user selects the operation mode of the drones 100 as the automatic flight mode, the drones 100 are automatically taken off and landed at predetermined times by the user, And the temperature of the thermal image can be measured through the camera unit 120. While the drones 100 are performing the flight mission, the user can operate the controller 200 to operate the drones 100 The flight path can be modified at any time.

That is, the controller 200 communicates with the drones 100 to receive position information of the drones 100, thermal image information, and photographing information, and at the same time, the drones 100 and 120 It controls the operation.

This is to prevent a human error that may occur in the inactivity of the user to the remote controller.

The controller 200 includes a flight mode selection unit 210, a photographing mode selection unit 220, and a camera control unit 230.

First, the flight mode selection unit 210 selects an operation mode of the drone 100 as a manual flight mode or an automatic flight mode in which the coal is stored by the position information storage unit 202 along a predetermined flight path, As shown in FIG.

The photographing mode selection unit 220 is provided to select one of the continuous mode and the time selection mode for acquiring thermal image information through the thermal imaging camera.

In other words, the photographing mode selection unit 200 is divided into a "continuous mode" and a "time selection mode", and a photographing mode can be selected through an operation. If the driver selects the "continuous mode" ) Records the temperature measured every 0.5 second to the first decimal place, and records the measured place and measurement time in the form of YYMMDDHHMMSS.

Then, if the driver selects the " time selection mode ", the user can select a time between 1 second and 10 seconds, for example, if the user selects 1 second, Record the temperature measured in intervals to the first decimal place and record the measured place and the measurement time in the form of YYMMDDHHMMSS.

[ And monitor the flight state of the drones 100 by comparing the flight path with a predetermined flight path.

Here, all the images photographed by the camera unit 120 are wirelessly transmitted to the controller 200 via the thermal image information receiving unit 260, so that the corresponding images are displayed on the monitor 240 through the controller 200 And the main server 300 transmits information about the video.

The main server 300 receives and reads the thermal image information and the photographed image information from the controller 200, outputs a plurality of control commands corresponding to different alarm states according to the temperature information acquired through the readout result, And stores image information and image information.

More specifically, the main server 300 outputs different control commands corresponding to the warning alarm, the warning alarm, and the red alarm according to the temperature information.

In other words, the temperature of the heating element, that is, the coal, measured in the flight of the drones 100 is transmitted and collected to the main server 300 through the controller 200 and the thermal image information collecting part 310, If the measurement temperature of the coal measured in the temperature measurement record unit 320 is between 40 ° C and 50 ° C, a warning alarm is generated through the alarm status unit 330. If the measurement temperature of the coal is between 50 ° C and 60 ° C, And when the measurement temperature of coal is between 60 ° C and 70 ° C, a red alarm is generated.

At this time, if a warning alarm (40 ° C to 50 ° C) is detected through the main server 300, an alarm is displayed on the monitor 240 and a control command is output to the monitor 240 so that the captured image information is displayed And stores the temperature, position, occurrence time, etc. of the alarm occurrence point in the main server 300.

If a yellow alarm (50 ° C to 60 ° C) is detected through the main server 300, a yellow alarm is displayed on the monitor 240, and the drones 100 at this time automatically detect 3m A rectangular area of ~ 10 m is searched for 1 minute.

Such a concentrated search area can be set by the user through the controller 200 of the field control room in a range of maximum 3 m to 10 m in 1 m increments. If the measured temperature of the centralized search area exceeds an average of 50 ° C, after 30 seconds of delay, the main server 500 automatically activates the dust suppression system 400 to lower the coal temperature of the zone, The temperature, the position, the generation time, and the operation time of the dust suppression system 400 in the main server 300.

After the drones 100 have completed the central search for one minute as described above, the drone 100 moves to the predetermined flight path and performs the mission.

If the red alarm (60 ° C. to 70 ° C.) is detected through the main server 300, a red alarm is displayed on the monitor 240. At this time, the drones 100 are automatically set to 3 m A rectangular area of ~ 10 m is searched for 1 minute.

Such a concentrated search area can be selected in a range of 3 m to 10 m in a maximum of 1 m through the controller 200 by the user's operation in the same manner as in the case of the yellow alarm, ° C, the dust suppression system 400 is automatically operated after 30 seconds delay to lower the coal temperature in the corresponding zone, send the low-fire alarm to the fire alarm system 500, Information on low-emission red alarms is sent to enable quick initial response.

At this time, the temperature, the position, the time of occurrence, the dust suppression system 400, and the operation time of the fire alarm system 500 are stored in the main server 300, and the drones 100 are stored for 1 minute After finishing the search, the user moves to the previously designated flight path to perform the mission.

Meanwhile, in the fire alarm system according to the present embodiment, when the temperature in the caution step (40 ° C) or more is detected, the main server 300 transmits the signal to the monitoring system 700, Immediately upon receiving the signal, the direction and angle of the surveillance camera installed at the adjacent position are adjusted to intensively search the area.

The main server 300 receives the information from the thermal image information unit 310, the alarm status unit 330 and the dron operation status storage unit 340 and receives the information from the user terminal 600 and the control center 800 In particular, the general image photographed by the drones 100 can be viewed in real time in the user terminal 600 and the control center 800, and not only can an already photographed image be reproduced, The data is automatically compressed and converted after a predetermined period of time (30 days), and the file can be permanently stored.

As a result, the fire alarm system according to the present embodiment captures thermal images and general images of coal stored in a low-fire state using a drone 100 equipped with a thermal camera and an ordinary camera, At the same time, the heating state of coal can be measured through analysis of the thermal image, and management and alarm corresponding to the heating state can be performed accordingly.
