[0002] Currently, when a fire breaks out in a mountainous area, the ground communication facilities will be damaged, resulting in communication interruption or weak communication signals, making it impossible for fire-fighting staff to timely understand the fire situation and carry out effective fire rescue. Therefore, after the ground communication facilities become ineffective, it is usually relied on that a UAV carries an optical fiber graphic module and flies to the mountainous fire area for emergency communication.

[0003] However, in the aforementioned prior art, the UAV communication method is just to simply fly to the mountainous area and then search for the fire area to arrange emergency communication. There are usually multiple ignition points in a mountainous fire. Therefore, the UAV cannot accurately and efficiently perform emergency communication for each ignition point by relying on blind flight, and the UAV equipment is expensive, and the number of UAVs equipped for fire-fighting staff is usually small; resulting in the inability to make the most of the limited number of UAVs for emergency communication coverage, which is not conducive to fire-fighting staff to efficiently and accurately understand the mountainous fire situation.

Detailed implementation manners

[0054] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present invention, and should not be construed as a limitation to the present invention.

[0055] Please refer to Figures 1 to 7 , the present invention provides an emergency communication system based on an unmanned aerial vehicle (UAV) optical fiber graphic module, specifically including:

[0056] The communication status recognition module 1 is used to recognize the communication status of fire - fighting equipment;

[0057] Specifically including:

[0058] The traditional communication device real - time monitoring unit 101 is used to monitor the signals of fire - fighting communication equipment by setting signal sensors;

[0059] Install the signal sensors on the fire - fighting communication equipment to monitor the signal strength of the fire - fighting communication equipment.

[0060] The device signal threshold setting unit 102 is used to set the signal threshold of fire - fighting equipment. When the signal is lower than the threshold, it indicates that the signal is weak and there is a risk of communication interruption;

[0061] By setting the signal threshold, the strength of the fire - fighting equipment signal can be monitored in real - time. Once the signal is lower than the threshold, the system can immediately detect potential communication problems, thereby taking measures for prevention or repair to avoid communication interruption; when the signal is lower than the threshold, the system can record and report relevant fault information, providing an important basis for subsequent fault troubleshooting and repair.

[0062] The acousto-optic reminder unit 103 is used to give an acousto-optic alarm after the signal is lower than the threshold to remind the surrounding firefighters to check and maintain.

[0063] The emergency deployment module 2 is used to automatically start the drone for emergency communication deployment when it recognizes that the communication status is poor;

[0064] Specifically, it includes:

[0065] The optical fiber graphic module installation unit 201 is used to complete the automatic installation of the optical fiber graphic module by setting a robotic arm on the drone base station, setting a buckle on the drone, and the robotic arm moving the optical fiber graphic module to the buckle.

[0066] By setting the robotic arm, the optical fiber graphic module can be automatically clamped and moved, and then fixed through the buckle. Furthermore, in case of an emergency, the installation can be automatically completed without manual operation, greatly improving the deployment efficiency of emergency communication.

[0067] The drone self-start unit 202 is used to automatically start the drone for fire coverage detection in the mountain area after an acousto-optic alarm.

[0068] After receiving the acousto-optic alarm, it indicates that the signal is weak. At this time, the drone directly self-starts and notifies the staff to go to the fire communication equipment for maintenance, which can significantly ensure the stability of communication and the efficiency of emergency deployment.

[0069] The drone charging unit 203 is used to automatically charge the drone when the drone is parked at the base station.

[0070] When the drone is not in use, relying on the charging gun set on the drone base station and the function of the robotic arm, the robotic arm drives the charging gun to move, and then charges the drone without manual operation, reducing the manual pressure and freeing up more personnel for fire rescue.

[0071] The single-area real-time communication module 3 is used to conduct separate real-time communication with the fire area in the mountain area through the drone;

[0072] Specifically, it includes:

[0073] The real-time shooting unit 301 is used to detect the mountain area through temperature and smoke sensors, and use a high-definition camera to conduct real-time shooting of the mountain area to obtain temperature, smoke, and picture data;

[0074] The fire analysis unit 302 is used to transmit the temperature, smoke, and picture data to the upper computer installed on the drone base station for fire analysis;

[0075] Temperature data can show the abnormal temperature in the mountain fire area, and smoke data can show the abnormal smoke content in the mountain fire area. After transmitting the combined picture data to the host computer, the staff can visually judge whether there is a fire. If the staff is not present, at this time, the preset temperature threshold and smoke threshold can be used to preliminarily judge whether a fire has occurred. If it is preliminarily judged that both the temperature and smoke exceed the threshold, then the picture data is identified using an image recognition algorithm. After identifying the flame or smoke, it can be confirmed that there is a fire.

[0076] The single - area is for the communication unit 303. After analyzing and confirming a fire, the UAV starts the optical fiber graphics module to conduct targeted real - time communication for this area.

[0077] After confirming that there is a fire in a certain area, the UAV that makes the confirmation does not need to scan the subsequent mountainous area. Instead, it directly conducts continuous real - time picture monitoring of this area and starts the optical fiber graphics module carried by the UAV for emergency communication in this area, so that firefighters can go to this area for fire rescue.

[0078] The multi - area coverage module 4 is used to conduct coverage detection of the mountain area through multiple UAVs according to a set route. After detecting a fire, the UAVs conduct real - time communication for this area;

[0079] Specifically including:

[0080] The UAV search mode switching unit 401 is used to be controlled by the fire - fighting staff in the host computer to switch the flight search mode of the UAV;

[0081] Set a preset time. If the flight duration of the UAV exceeds the preset time and no fire area is detected in the mountain area, then start the UAV search mode switching unit 401 to switch the flight search mode of the UAV, and then continue to search for the fire area in the mountain area, so as to avoid not detecting the fire area for a long time, and thus can flexibly change the search method, improving the search efficiency and search effect.

[0082] The UAV spiral diffusion search unit 402 is used to control multiple UAVs to conduct spiral diffusion search centered on the mountain area. When a UAV detects a fire, it starts the single - area real - time communication module 3 for real - time communication, and the remaining UAVs continue to search;

[0083] The UAV grid search unit 403 is used to control multiple UAVs to conduct grid - type coverage search centered on the mountain area. When a UAV detects a fire, it starts the single - area real - time communication module 3 for real - time communication, and the remaining UAVs continue to search;

[0084] The fixed - trajectory search unit 404 of the UAV is used for firefighters to remotely preset the flight trajectory of the UAV. Multiple UAVs perform fixed - line search according to the flight trajectory. When a UAV detects a fire, it activates the single - area real - time communication module 3 for real - time communication, and the remaining UAVs continue to search.

[0085] The multi - UAV docking module 5 is used to merge and display the fire pictures detected by each UAV, and splice the pictures of adjacent fire areas to improve the communication effect.

[0086] Specifically, it includes:

[0087] The UAV tracking unit 501 is used to track the position of each UAV, transmit the position information back to the UAV base station, and display it uniformly;

[0088] Track the position of each UAV so that the staff can observe the situation of the UAV at any time, avoid the situation of the UAV losing contact, and can search according to the last position display after losing contact.

[0089] The UAV information inter - communication unit 502 is used to transmit the status of each UAV back to the UAV base station. When a certain UAV is in the real - time communication state, the remaining UAVs automatically bypass the area located by the UAV tracking unit 501 during the search to avoid repeated detection of mountainous areas;

[0090] After tracking and understanding the position of each UAV, through data inter - communication between multiple UAVs, the situation of route overlap and mutual collision can be avoided. After avoiding overlap, the fire search efficiency can also be improved; at the same time, when a certain UAV is in the real - time communication state, it means that a fire situation has been found in this area. Then the remaining UAVs automatically bypass this area during the search to avoid repeated detection of mountainous areas, which can significantly improve the fire search efficiency and avoid wasting UAV resources.

[0091] The multi - area picture construction unit 503 is used to splice the real - time communication pictures of each UAV.

[0092] Specifically, it includes:

[0093] The mountain - area terrain construction sub - unit 5031 is used to comprehensively scan the mountain - area terrain during the UAV search, obtain the mountain - area terrain data, transmit the mountain - area terrain data back to the UAV base station, and input it into the modeling software for mountain - area terrain modeling to obtain a mountain - area model;

[0094] When the UAV searches for a fire, use the high - definition camera set on the UAV to take pictures of the mountain - area terrain, pre - process the obtained images (image correction, denoising, enhancement) to improve the quality and usability of the images, and input the pre - processed data into Pix4D Mapper to construct a mountain - area model.

[0095] The adjacent picture connection sub-unit 5032 is used to splice adjacent fire pictures detected by the UAV.

[0096] According to the position tracking of the UAV, the specific position of the UAV on the mountain area model can be obtained. Then, the fire area detected by the UAV is displayed on the mountain area model, and the picture is simulated and displayed on the mountain area model. If adjacent fire areas are found during the display, they will be automatically spliced for more intuitive viewing by the staff.

[0097] The single area viewing sub-unit 5033 is used to display the non-adjacent fire pictures detected by the UAV on the mountain area model and set click buttons for the fire-fighting staff to click and view.

[0098] For non-adjacent or far-away fire areas, when the staff wants to view them, they can click the click button set for that area on the mountain area model to view. At the same time, the display conditions of the fire area can be set in the host computer system. When the fire area is greater than the preset value, it is default that there is no need to click the button and it will be automatically displayed on the mountain area model. When the fire area is less than the preset value, it is default that the button needs to be clicked to display. Thus, the areas with severe fires can be displayed preferentially to remind the staff to deal with these areas first. The areas that need to be clicked can be given a flashing prompt.

[0099] Please refer to Figure 8 , the present invention also provides an emergency communication method based on a UAV optical fiber graphic module, including the following steps:

[0100] S1: Identify the communication status of the fire-fighting equipment;

[0101] S2: When the communication status is identified as poor, automatically start the UAV for emergency communication deployment;

[0102] S3: Use multiple UAVs to conduct a coverage detection of the mountain area according to the set route;

[0103] S4: After detecting a fire, the UAV conducts real-time communication in this area;

[0104] S5: Combine and display the fire pictures detected by each UAV, and splice the pictures of adjacent fire areas.

[0105] Among them, identify the communication status of the fire-fighting equipment; when the communication status is identified as poor, automatically start the UAV for emergency communication deployment; use multiple UAVs to conduct a coverage detection of the mountain area according to the set route; after detecting a fire, the UAV conducts real-time communication in this area; combine and display the fire pictures detected by each UAV, and splice the pictures of adjacent fire areas.
