Description

wildfire spread defense line establishment system

[0001] The present invention relates to a remote firefighting system for constructing a defensive line to suppress the spread of wildfires, and more specifically, to a system that enables remote control of firefighting equipment using an excavator, which includes equipment for constructing a wildfire defensive line where fire trucks cannot enter, in order to suppress the spread of wildfires when a wildfire occurs, and which suppresses the spread of wildfires in situations where the deployment of aerial firefighting equipment is impossible at night, while preventing casualties and allowing for the recording, preservation, and utilization of data via video.

[0002] In Korea, mountainous terrain accounts for 70% of the land area, so the frequency of wildfires is quite high during the dry seasons of spring and autumn. Wildfires are one of the types of fires that are very difficult to suppress due to natural variables such as wind changes, in addition to causing significant damage.

[0003] Because these wildfires travel on the wind and destroy forests, the damage is very severe if they are not quickly suppressed in the early stages.

[0004] Therefore, wildfire monitoring cameras are being installed to monitor for wildfires in real time for their initial suppression. These cameras are installed around mountain peaks or along ridges in mountainous terrain and are configured to monitor the entire area of ​​the mountainous landscape.

[0005] Forest fire surveillance cameras are installed on high terrain, such as around mountain peaks or ridges, to monitor for forest fires over a wide area. Generally, the installation process involves erecting tall vertical towers in mountainous terrain and mounting the cameras on top of the towers.

[0006] According to this installation method, the installation cost increases significantly, such as the need to install large vertical towers in rugged mountainous terrain. Furthermore, since wildfire monitoring cameras can only detect simple smoke, it is difficult to accurately determine whether a wildfire has occurred, and there are many inconveniences, such as workers having to be dispatched to the site to personally verify the occurrence of the wildfire, which is why it is not very effective for preventing wildfires.

[0007] In addition, even if a wildfire is detected early through a wildfire surveillance camera, fire trucks cannot enter the fire site due to the mountainous terrain, so firefighters have to carry heavy firefighting equipment to the site to extinguish the fire, which is inconvenient. In particular, when firefighters working below the ridge, flames descend to surround them, causing serious casualties.

[0008] To solve these problems, firefighting helicopters that spray fire extinguishing agents or water from the air have been developed. However, in areas with rugged terrain and strong winds, the fire extinguishing agents sprayed from the air cannot properly reach the fire site. Additionally, flames and smoke caused by the updrafts generated by the wildfire obstruct the firefighting helicopter's visibility, exposing it to the risk of safety accidents. Furthermore, even when using such firefighting helicopters to suppress wildfires, the cost of fire suppression increases significantly, considering the high operating costs of the helicopters.

[0009]

[0010] The wildfire extinguishing device and method using a helicopter involves suspending a bucket from a helicopter with a rope or similar means to fill it with firefighting water from a river or lake, flying to the wildfire area, and then opening a hinged valve installed on the underside of the bucket to discharge the water; or the helicopter itself is equipped with a water tank and a pump to fill the tank with firefighting water from a river or lake using the pump, flying to the wildfire area, and then opening a hinged valve installed on the underside of the tank to discharge the water. These methods have been carried out only during the day, from sunrise to sunset, and wildfire extinguishing could not be performed at night.

[0011] Legal regulations prohibit the use of helicopters for wildfire suppression after sunset. This is because it is dangerous after dark, as visibility of mountain ridges and large trees is compromised. This regulation is intended to protect the safety of the helicopter and the lives of the passengers.

[0012] Therefore, devised to overcome these conventional drawbacks, the objective of the present invention is to enable fire suppression even at night via remote control of a fire suppression device utilizing an excavator that includes equipment for constructing a fire defense line where fire trucks cannot enter, in order to suppress the spread of a forest fire when it occurs.

[0013] Another objective of the present invention is to suppress the spread of wildfires, establish a defensive line, and enable the recording, preservation, and utilization of data via video, while minimizing casualties in situations where the deployment of aerial firefighting equipment is impossible at night.

[0030] The present invention provides the effect of enabling firefighting operations not only during the day but also at night by utilizing an excavator equipped with equipment for constructing a fire defense line where fire trucks cannot enter to suppress the spread of a wildfire when it occurs, and by enabling the supply of firefighting water from a fire truck and, if necessary, utilizing a water pump to overcome elevation differences with appropriate water pressure while remotely controlling the suppression equipment at the required location.

[0031] The present invention enables fire control in situations where the deployment of aerial firefighting equipment, such as helicopters and drones, is impossible at night, thereby effectively suppressing the spread of wildfires, establishing defensive lines, and preventing loss of life. Furthermore, it provides the effect of enabling the construction of fire control data through the recording, preservation, and utilization of video footage of the wildfire and control status.

[0032] The present invention enables the deployment of a suppression device at times and locations where the deployment of nighttime and aerial firefighting equipment is impossible, and thereby provides the effect of protecting forests and preventing loss of life by establishing a defensive line that suppresses the spread of wildfires.

[0084] It is connected to transmit and receive via the transmitter and receiver through the aforementioned wireless router, and includes installing a Web RTC viewer and a remote remover connected to the router to enable remote control.

[0085]

[0086] FIG. 6 shows a system configuration diagram of a remote control state representing the most preferred embodiment of the present invention,

[0087] In order to establish a defense line to suppress the spread of a wildfire at night when a wildfire occurs, a remotely controllable excavator (30, 30a) is supplied, and a remote controller (50) is installed in a control room for remote control of the excavator (30, 30a), and the monitor (51) includes being connected to a surveillance camera (45) or connected to a conventional surveillance camera installed in the mountains for the purpose of monitoring wildfires.

[0088] A monitor (51) and a video receiver (52) are connected, and the video receiver (52) is connected to transmit and receive via an LTE router (53) and a transmitter / receiver (54).

[0089] The above LTE router (53) is connected to the cluster monitor (61) on the cluster PC (60) through the element hub (55), and the element hub (55) is connected to the start (75), pedal (71), status LED (72), and multi-function (73) on the DOD board (56), and is configured to be connected to the automatic board (57) and the driving control (43) device on the DOD board (56).

[0090] It is preferable that the remote controller (50) be installed in the control room, and the remaining system is installed on each excavator (30, 30a) so that the excavator (30, 30a) can be remotely controlled from the command center to establish a defensive line for suppressing the spread of wildfires at night.

[0091]

[0092] The remote firefighting system for establishing a defensive line to suppress the spread of wildfires according to the present invention, constructed in this manner, installs a defensive line in advance to prevent the spread of fire when suppression is impossible at night, in order to prevent damage to property caused by the fire spreading to important facilities such as houses or temples in the mountains or to places requiring fire suppression when a wildfire occurs.

[0093] The above system may be a road in a wildfire area, a forest road installed in the wildfire area, or a place where an excavator (30, 30a) can enter and be installed to prevent the spread of wildfire, and is installed to prevent further spread of wildfire by securing a path to remove trees, etc. by itself during the day using the gripper and pocket of the excavator (30, 30a) and the saw blade (71) installed on the control member (70), etc.

[0094] During the day, the path is secured in advance using an excavator (30, 30a) to allow entry, and a fire hose (12) is connected to the fire truck (10). In order to prevent problems with water spraying due to a drop in water pressure of the fire water (41) caused by the distance being long or the difference in altitude, a water supply pump (20) may be additionally installed on one part of the fire hose (12), and the fire water (41) can be supplied by connecting it to the excavator (30) through the fire hose (12a) connected to the water supply pump (20).

[0095] The above firefighting water (41) is supplied to the excavator (30) and stored in an auxiliary water tank (48) installed in the main body (31) so that it can be supplied when needed, and the firefighting water (41) can be directly supplied and sprayed when constructing a defense line using a fire hose (12, 12a).

[0096] The excavator (30), which has moved to the required location via wheels (32), etc., remains stationary to establish a defensive line to prevent the spread of wildfires, and another excavator (30a) moves from the excavator (30) to secure a path on its own, and firefighting water (41) can be supplied by installing a water pump (20a) to prevent a drop in water pressure due to distance or elevation difference from the fire hose (12b) connected to the water tank (11) of the excavator (30) or fire truck (10) and then connecting it to the excavator (30a) through a new fire hose (12c).

[0097] An auxiliary water tank (48) is installed in the main body (31) of the above-mentioned excavator (30a) to secure firefighting water in advance, and in this way, a road is secured by using the excavator (30, 30a) during the day, and a water supply pump (20, 20a) is installed on the road to prevent the water pressure of the firefighting water (41) from dropping between the fire hoses (12, 12a, 12b, 12c).

[0098] In the process of securing a road using the above-mentioned excavator (30, 30a), the excavator (30, 30a) can be driven directly by the operator to perform the task of securing the road, and if necessary, the task of securing the road can be performed through a remote controller (50).

[0099] In order to prevent the spread of wildfires and to protect important facilities such as houses and temples in the mountains, a defensive line is established by using an excavator (30, 30a) during the day to secure a path.

[0100] In this way, a fire truck (10), a water pump (20, 20a), and an excavator (30, 30a) can be installed in advance during the day to establish a defense line. This allows the movement of the wildfire to be monitored from the control room in situations where nighttime firefighting is impossible, and as the wildfire moves toward the area where the defense line has been established, the excavator (30, 30a) can be operated unmanned from the control room to establish a defense line to prevent the spread of the wildfire.

[0101] That is, the excavator (30, 30a) can be brightly illuminated through a light (44) to check the situation in front, and the surrounding situation of the excavator (30, 30a) can be checked in the control room through a surveillance camera (45). As a result, water is supplied to the excavator (30) and auxiliary water tank (48) through a fire hose (12, 12a) from the water tank (11) of the fire truck (10), and firefighting water (41) is supplied from a fire extinguisher (40) installed in front of the removal member (70) to absorb moisture in the surrounding trees or soil to prevent the spread of the wildfire, and at the same time, firefighting water (41) is supplied to the fire area (80) to extinguish the wildfire.

[0102] With the above-mentioned excavator (30, 30a) established as a defensive line to prevent the spread of wildfire, the control room operates the remote controller (50) to drive the excavator (30, 30a) respectively, thereby controlling the arm angle rotation movement of the fixed member (33) and the driving member (34) through the driving guide member (35), and by controlling the rotation angle of the fire extinguisher (40) through the linkage of the auxiliary member (36) with the control member (70) connected to the driving member (34), the spray angle of the fire extinguishing water (41) is controlled, thereby allowing the fire extinguishing water (41) to be supplied to the desired precise location.

[0103] The direction and location of the supply of firefighting water (41) through the above fire extinguisher (40) can be established by checking the situation in the control room through the fire monitoring camera (42) installed in the control member (70).

[0104] In particular, since control of the excavator (30, 30a) can be performed in this control room, in a reality where wildfire extinguishing operations cannot generally be carried out at night, the worker can leave the site and assess the surrounding conditions from the control room, thereby preventing the spread of the wildfire and protecting important facilities such as houses and temples in the mountains from the wildfire.

[0105]

[0106] A remote controller (50) is installed in the control room that controls the above-mentioned excavator (30, 30a), etc., so that various functions can be performed. In the event of a wildfire, a remotely controllable excavator (30, 30a) is supplied to establish a defense line to suppress the spread of wildfire at night. The entire situation can be understood and recognized through a monitor (51) connected to a surveillance camera (45) or a conventional surveillance camera installed in the mountains for the purpose of monitoring wildfires.

[0107] A monitor (51) and a video receiver (52) are connected so that the surrounding situation can be checked or video can be saved and secured as data, and the video receiver (52) is connected to transmit and receive via an LTE router (53) and a transmitter / receiver (54).

[0108] The above LTE router (53) is connected to the cluster monitor (61) on the cluster PC (60) via the element hub (55), and the element hub (55) is connected to the start (75), pedal (71), status LED (72), and multi-function (73) on the DOD board (56), and the DOD board (56) is connected to the automatic board (57) and the operation control (43) device to control the excavator (30, 30a) unmanned from the control room and establish a defense line to prevent the spread of wildfire.

[0109] The above remote controller (50) is preferably installed in the control room, and the remaining system is installed in each excavator (30, 30a), so that the excavator (30, 30a) can be remotely controlled from the control room to establish a defensive line for suppressing the spread of wildfires at night.

[0110]

[0111] Therefore, in the event of a forest fire, an excavator (30, 30a) is operated during the day to protect important facilities such as houses and temples in the mountains and to establish a defense line against the spread of the forest fire. This allows the excavator to secure a path independently, connect a fire hose (12, 12a, 12b, 12c) from a location accessible to a fire truck (10), and simultaneously install a water pump (20, 20a) to maintain water pressure. After installing the excavator (30, 30a) at the location where the defense line against the spread of the forest fire is established, the excavator (30, 30a) can be operated to supply firefighting water (41) to the necessary location while monitoring the surrounding situation from the control room during nighttime when forest fire extinguishing operations are impossible. Consequently, the defense line construction work to prevent the spread of the forest fire can be conveniently performed unmanned even at night, thereby providing a groundbreaking system for forest fire control operations. Furthermore, it is possible to prevent loss of life through remote control and to establish practical data for forest fire control and prevention, such as recording, storing, and utilizing data, by transmitting video in real time. It is.
