Description

Technical Field

[0001] The present invention belongs to the technical field of fire monitoring, and specifically relates to a system and monitoring method for an integrated communication, navigation, and remote sensing satellite for forest fire monitoring. Background Art

[0002] Forest fires are one of the natural disasters that seriously threaten the ecological environment and human safety. Current forest fire monitoring systems often have problems such as monitoring delays, monitoring blind spots, and untimely data transmission, which limit the effectiveness of fire monitoring and emergency response.

[0003] In recent years, with the rapid development of infrared thermal imaging technology, infrared thermal imaging technology has been widely used in the field of fire monitoring technology. Since infrared thermal imaging technology directly images the temperature field and has fine temperature measurement, a temperature difference generally higher than 0.05 °C from the ambient temperature can be imaged. And due to its sensitive application, it has gradually become an indispensable technical means in forest fire prevention technology. Due to the heat-sensing characteristics of infrared thermal imagers, video monitoring systems using infrared thermal imagers can more quickly warn of fire situations such as thick smoke, underground fires, and hidden fires, and extinguish the fire in the budding stage in a timely manner.

[0004] When related technologies use infrared thermal imaging technology to detect fires over a large area, usually after confirming the approximate location of the fire, an alarm signal is transmitted through relevant alarm systems and devices. After local relevant departments and personnel receive the alarm signal, they need to rush to the alarm location to confirm and prevent the fire. When the detected fire is at a relatively long distance, relevant personnel need to rush to the approximate location where the monitoring device is located under the guidance of tools such as positioning devices and maps. In mountainous areas, forests and other regions, due to problems such as poor signal and inconvenient communication, relevant personnel cannot quickly and accurately reach the alarm location. And when the detected fire is a hidden fire such as an underground fire or a hidden fire, after relevant personnel rush to the approximate location of the alarm, they still need to search for the fire point. Therefore, it takes a lot of time from when the monitoring device discovers the fire to when relevant personnel determine the location of the fire point, which is not conducive to the control and extinguishment of the fire. In view of this, the present invention proposes a system and monitoring method for an integrated communication, navigation, and remote sensing satellite for forest fire monitoring to solve the above technical problems.

[0044] In order to make the technical means, creative features, achieved purposes, and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0045] As Figures 1 to 8 shown, a system for a forest fire monitoring communication, navigation, and remote sensing integrated satellite according to the present invention includes a monitoring module, a data processing module, and a guiding module;

[0046] The monitoring module obtains a thermal radiation image through infrared imaging. The monitoring module includes a multi-spectral infrared monitoring unit and a planning unit;

[0047] The multi-spectral infrared monitoring unit includes a multi-spectral infrared imaging device and an observation satellite for carrying the multi-spectral infrared imaging device. The observation satellite is used for real-time monitoring of the observation area. The multi-spectral infrared imaging device is paired with the observation satellite to perform multi-band and high-resolution infrared imaging on the observation area to generate an infrared image;

[0048] The planning unit is a pre-set program. The planning unit is used to control the operation area, operation orbit, and observation range of the communication, navigation, and remote sensing integrated satellite. The planning unit includes an area delineation component, an orbit planning component, and a period adjustment component;

[0049] The data processing module is used to receive and process the observation results output by the multi-spectral infrared detection unit. The data processing component includes a data transmission unit, an analysis unit, and a warning unit;

[0050] The data transmission unit is used to receive the infrared image generated by the multi-spectral infrared monitoring unit and transmit it to the analysis unit. Under the action of a pre-set program, the analysis unit analyzes the infrared image;

[0051] The analysis unit includes a threshold setting component and an information comparison component;

[0052] The threshold setting component is a temperature value preset manually, and the information comparison component is used to compare each coordinate value in the infrared image with the threshold and output the relevant information exceeding the threshold;

[0053] The analysis unit is connected to the warning unit. The information comparison component outputs the relevant information to the warning unit, and the warning unit issues an alarm;

[0054] The guiding module reads the relevant information transmitted to the warning unit and guides the rescue according to the relevant information. The guiding module includes an information reading unit and a prompting unit;

[0055] The information reading component is connected to the warning unit. The information reading component is used to read the coordinate information in the relevant information. The prompting unit includes a mobile device and a warning device. The warning device is installed on the mobile device, and the warning device is used to transmit warning information;

[0056] The mobile device is a drone 1. The mobile device and the warning device are designed in plural and correspond to each other one by one;

[0057] The observation satellite is a communication-navigation-remote sensing integrated satellite with high resolution, wide coverage and real-time monitoring capabilities;

[0058] By monitoring the forest, when a forest fire occurs, it is part of the forest fire warning and prevention measures to detect the fire timely and accurately in the early stage. If the fire is detected in time, it can be intervened when the affected area of the fire is small and the extinguishing is relatively simple, thus reducing the losses caused by the fire. In the early stage of a fire, especially an underground fire or an invisible fire, due to the small spread range of the flame, few ignition sources, and even the lack of obvious phenomena such as thick smoke generated by the flame, it is difficult to detect the fire and the human intervention is not timely enough. The present invention enables the fire to be detected in time in the early stage by setting up a monitoring module, a data processing module and a guiding module, locates the fire, facilitates the fire extinguishing personnel to arrive at the fire area timely and accurately, realizes the intervention of the fire, and reduces the spread and affected range of the fire;

[0059] Specifically, in the early stage of a fire, especially an underground fire or an invisible fire, although the external manifestations of the fire, such as thick smoke, are not obvious due to factors such as a small scope, there is a large temperature difference between its temperature and the ambient temperature. Therefore, it can be observed by a multi-spectral infrared imaging device in a timely manner. In the present invention, the multi-spectral infrared imaging device is installed on an observation satellite, which is launched and deployed in space together with the observation satellite. Under the action of the planning unit, the operating area, orbit, and observation range of the observation satellite are controlled by a period adjustment component, an orbit planning component, and a region demarcation component respectively, and the period adjustment component, the orbit planning component, and the region demarcation component are all pre-set programs. Therefore, the staff can change the program to make the observation satellite observe the forest according to actual needs. During the observation process, the multi-spectral infrared imaging device performs infrared imaging on the observed image and finally outputs an infrared image. The output infrared image is transmitted to the data processing module. The data transmission unit in the data processing module is dedicated to transmitting data. After the infrared image is converted and transmitted to the analysis unit, the analysis unit compares and analyzes the data in the infrared image. By reading the temperature information of each coordinate point in the infrared image and comparing it with a pre-set threshold, when the temperature value of a local area exceeds the pre-set threshold, it is determined that this area is an abnormal area at this time. The analysis unit transmits the relevant information of this coordinate point to the warning unit. It should be noted that the relevant information is at least a set of the coordinate information corresponding to the abnormal area and the temperature information of the abnormal area. After the relevant information is transmitted to the warning unit, the warning unit summarizes the relevant information of the abnormal area determined in the current observation area and issues an alarm to remind relevant personnel to check and confirm. At the same time, when the information in the warning unit is confirmed, the staff manually activates the guidance module. The guidance module is signal-connected to the warning unit, and the information reading unit is automatically connected to the warning unit and extracts the coordinate information from the relevant information summarized in the warning unit and outputs it to the prompt unit. The prompt unit moves to the sky above the abnormal area according to the coordinate information and transmits a warning message through a warning device. The transmission of the warning message is convenient for the patrol personnel located around the abnormal area to discover, and at the same time, it can also provide positioning for the rescue personnel who go to confirm the fire situation, facilitating the relevant personnel to quickly rush to the abnormal area to interfere with the fire artificially;

[0060] The present invention uses an observation satellite and a paired infrared imaging device to perform infrared imaging observations on forest areas at high altitudes, effectively improving the accuracy and timeliness of fire monitoring, facilitating large-scale monitoring of forest areas. After detecting a suspected fire situation, while sending an alarm and providing coordinate information for rescue personnel, a warning message is transmitted over the abnormal area through a guiding component, thereby providing a guiding service for rescue personnel to approach quickly. At the same time, the range of the warning message transmitted by the warning device can be utilized to enable the people near the abnormal area to timely obtain fire information, providing guidance for activities such as the evacuation of people and the confirmation of the abnormal area.

[0061] As a preferred embodiment of the present invention, the analysis unit further includes a region generation component and a prediction component;

[0062] The region generation component reads the coordinate information and temperature information output by the information comparison component, and generates a fire distribution map based on the coordinate information and temperature information. The prediction component cooperates with the region generation component, predicts the fire change trend according to the fire distribution map, and outputs the fire change prediction result and the fire distribution map together;

[0063] After the information comparison component compares the temperature values in the infrared image with a preset threshold, the relevant information of the abnormal area is transmitted to the early warning unit. During this process, the region generation component and the prediction component read the coordinate information and temperature information in the relevant information output by the information comparison component, and under the action of a preset program, generate a fire distribution map by combining the coordinate information of multiple abnormal areas. The prediction component, with the cooperation of the temperature information, predicts the change of the fire, and outputs the prediction result and the fire distribution map together, providing a certain reference for the rescue activities of the staff.

[0064] As a preferred embodiment of the present invention, the guiding module further includes a layout planning unit, in which a map of the observation area is stored, a locator is installed in the prompting unit, and the layout planning unit plans the distribution position of the prompting unit by reading the position of the locator in the map and combining the fire distribution map;

[0065] After obtaining the coordinate information of the abnormal area, the prompt unit moves towards the coordinate position. During this process, the layout planning component, through the pre-stored map, the coordinate information of the abnormal area, and the locator installed in the prompt unit, under the action of a pre-set program, guides the prompt unit to quickly approach the abnormal area. And because both the moving device and the warning device in the prompt unit are designed in plural, when the layout planning component plans the movement path of the moving device, it simultaneously guides the combination of multiple moving devices and warning devices to disperse and surround the abnormal area. On the one hand, dispersing and surrounding can expand the warning range of the warning device, facilitating people near the abnormal area to receive information. On the other hand, using the prompt unit to surround the fire abnormal area makes it more convenient for rescue personnel to judge the specific location of the fire. And during the rescue process, when the fire gradually expands, the movement of the prompt unit can also prompt relevant rescue personnel to clearly understand the relevant situation of the fire.

[0066] As a preferred embodiment of the present invention, the warning device includes a searchlight 2, a sound alarm, and a smoke canister 21. The searchlight 2 and the sound alarm are both installed on the unmanned aerial vehicle 1. The smoke canister 21 is a cavity-type structure with small holes on its surface. The smoke canister 21 is filled with a smoke agent. An igniter 3 is installed in the smoke canister 21. The smoke canister 21 is fixedly connected to the unmanned aerial vehicle 1 through a connecting rope 4.

[0067] When guiding and warning through the prompt unit, the unmanned aerial vehicle 1, as a mobile device, can quickly approach the abnormal area in the air. When it reaches the position determined by the layout planning component, the searchlight 2 and the sound alarm installed on the unmanned aerial vehicle 1 are activated, providing a guiding effect through sound and light, guiding the surrounding patrol personnel or rescue personnel. And when the fire occurs during the day, the light emitted by the searchlight 2 cannot play a guiding role. At this time, the existence of the smoke canister 21 enhances the visibility of the prompt unit. Specifically, after the unmanned aerial vehicle 1 reaches the designated position, the igniter 3 in the smoke canister 21 is activated, causing the smoke agent in the smoke canister 21 to burn. The smoke agent used in this embodiment is a mixture of powdered sugar, a coloring agent, and potassium nitrate powder. When the smoke agent is ignited, colored smoke is generated, and the colored smoke diffuses out through the holes on the smoke canister 21, thereby enhancing the visibility of the warning device.

[0068] As a preferred embodiment of the present invention, the smoke tank 21 includes a tank body 22, a mounting rod 23 and a winding wheel 24. The mounting rod 23 is fixedly installed on the tank body 22. The winding wheel 24 is rotatably connected to the mounting rod 23. The connecting rope 4 is wound around the winding wheel 24 and is used to connect the winding wheel 24 and the drone 1. A sorting rail 25 is installed on the drone 1. The inner wall of the sorting rail 25 is made of an elastic material. The mounting rod 23 is clamped inside the sorting rail 25. An electric telescopic rod 26 is fixedly installed on the drone 1. The electric telescopic rod 26 extends into the sorting rail 25. The mounting rod 23 is located on the moving path of the electric telescopic rod 26;

[0069] In practical applications, in order to reduce the obstruction of the movement of the drone 1 caused by the presence of the smoke tank 21, by setting the sorting rail 25, the smoke tank 21 is installed on the sorting rail 25. When the drone 1 reaches the designated position, the electric telescopic rod 26 extends, pushing the mounting rod 23 to slide between the sorting rails 25. Finally, the mounting rod 23 disengages from the sorting rail 25. At this time, under the action of gravity, the smoke tank 21 falls downward. During the falling process, the connecting rope 4 wound around the winding wheel 24 gradually unfolds, causing the smoke tank 21 to be suspended below the drone 1. When the smoke in the smoke tank 21 diverges, on the one hand, the presence of the smoke can make the light of the searchlight 2 easier to observe, and on the other hand, the smoke flows from top to bottom, facilitating the staff to judge the abnormal position.

[0070] As a preferred embodiment of the present invention, the igniter 3 includes a rotating shaft 31. The rotating shaft 31 is installed on the winding wheel 24. The rotating shaft 31 penetrates through the mounting rod 23 and the tank body 22 and extends into the inner cavity of the tank body 22. A friction plate 32 is fixedly installed in the inner cavity of the tank body 22. A friction rod 33 is installed on the rotating shaft 31. The friction plate 32 is located on the rotation path of the friction rod 33. The end of the friction rod 33 is coated with a mixture of potassium sulfide and tetraphosphorus trisulfide;

[0071] When the smoke tank 21 moves downward, initially, the connecting rope 4 wound around the winding wheel 24 gradually unfolds. During the unfolding process, the winding wheel 24 rotates, driving the rotating shaft 31 to rotate, causing friction between the friction rod 33 and the friction plate 32. In the present invention, the mixture of tetraphosphorus trisulfide and potassium sulfide coated on the end of the friction rod 33 can catch fire under the action of frictional heat, thereby igniting the smoke agent in the smoke tank 21.

[0072] As a preferred embodiment of the present invention, the connecting rope 4 is designed in multiple sections. Multiple smoke tanks 21 are provided. The connecting rope 4 corresponds to the smoke tanks 21 one by one. Multiple smoke tanks 21 are connected in series through the connecting rope 4 in sequence;

[0073] By setting multiple smoke cans 21, during the process of the electric telescopic rod 26 extending, the multiple smoke cans 21 are successively disengaged from the sorting track 25 and finally arranged in sequence below the unmanned aerial vehicle 1. Moreover, the multiple smoke cans 21 emit colored smoke simultaneously, further enhancing the visibility of the warning device.

[0074] As a preferred embodiment of the present invention, both the smoke cans 21 and the sorting track 25 are evenly distributed on both sides of the unmanned aerial vehicle 1;

[0075] The smoke cans 21 and the sorting track 25 are respectively arranged on both sides of the unmanned aerial vehicle 1, making the gravity on both sides of the unmanned aerial vehicle 1 balanced in the initial state, which is convenient for the rapid movement of the unmanned aerial vehicle 1.
