Description

Technical Field

[0001] The present application relates to the field of disaster relief communication technology, and in particular to a disaster relief on-site communication system and working method. Background Art

[0002] At the disaster relief site, communication interruptions are often prone to occur, which greatly affects the disaster relief work. At present, drones can be used to form a communication link above the disaster relief site to ensure smooth communication between search and rescue personnel and the command center.

[0003] However, even after communication issues are resolved, the issue of timely rescue remains. For small disaster sites, rescuers can concentrate on searching and rescuing the injured, providing centralized accommodation and treatment. However, for larger disaster sites, such as earthquakes, floods, and wildfires, the area is vast, the injured are widely dispersed, and the search and rescue process takes a long time. In these situations, rescuers struggle to simultaneously search and rescue the injured in all areas. After rescuing the injured, rescuers often evacuate them and then return to search for more. This delay significantly hinders the timely rescue of additional injured. Another approach is to arrange for some rescuers to remain at the scene to assist the injured, while the remaining rescuers continue the search and rescue efforts. However, this approach requires more manpower and also hinders the timely treatment of injured patients. Finally, rescuers leave minor injuries where they are and contact the command center to arrange for personnel to evacuate them. Rescue workers then continue their search and rescue efforts.

[0004] Obviously, the latter approach is more suitable for large-scale search and rescue operations. However, this approach still has its flaws: after contacting the command center, rescuers are unable to transmit the injured person's exact location. Instead, they can only roughly locate the injured area using the drone's built-in GPS function. In mountainous areas, the terrain is complex, and even if the general area is located, it is difficult for external reinforcements to reach the injured person in time, which often delays treatment.

[0005] Furthermore, search and rescue personnel may become lost in areas with complex terrain, putting them in danger themselves. Especially when communication networks are unexpectedly disrupted, the command center struggles to contact rescuers and obtain their location. In such situations, the personal safety of rescuers cannot be guaranteed.

[0006] To address the above-mentioned problems, no effective solutions have been proposed so far. Summary of the Invention

[0007] In response to the shortcomings of the existing technology, the purpose of the present invention is to disclose a disaster relief site communication system and working method, which can maximize the guarantee that the injured are treated in time and the safety of the rescue personnel themselves, and at least solve the technical problem of untimely rescue caused by communication failures in related technologies in large-scale disaster relief scenarios.

[0014] Optionally, the MCU module obtains the first position parameter from the positioning module, including: using the signal strength detection module to periodically detect the wireless connection signal strength between the first wireless connection module and the second wireless connection module, when the wireless signal strength is lower than the threshold, the control unit sends a second instruction to the MCU module through the second wireless connection module and the first wireless connection module; the MCU module obtains the first position parameter from the positioning module based on the second instruction.

[0030] Example 1

[0031] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0032] According to an embodiment of the present invention, a disaster relief site communication system is provided, which is mainly used to provide a communication solution in scenarios where the disaster covers a relatively large area, to ensure smooth, accurate and timely information exchange between rescue personnel and the command center, so that the command center can accurately obtain the location of the injured and the location of the rescue personnel, so as to maximize the guarantee of timely rescue of the injured and disaster relief and support for the rescue personnel.

[0033] According to one aspect of an embodiment of the present application, a disaster relief site communication system is provided, comprising:

[0034] The first terminal includes an MCU module, a positioning module, a first wireless connection module and a key module, and the positioning module, the first wireless connection module and the key module are all electrically connected to the MCU module; the unmanned module includes a drone, and the drone is provided with a control unit, a communication module and a second wireless connection module, and the communication module and the second wireless connection module are both electrically connected to the control unit, and a short-distance wireless connection is achieved between the control unit and the MCU module through the first wireless connection module and the second wireless connection module; the second terminal realizes a long-distance communication connection with the control unit through the communication module.

[0035] Figure 1 For a logical framework diagram of an embodiment of the present invention, please refer to Figure 1 In this embodiment, the disaster relief site communication system includes a first terminal 10, a drone module and a second terminal 30.

[0036] Among them, the first terminal 10 can be a personal device, mobile phone, computer or other communication device with positioning function carried by the rescue personnel themselves. The first terminal 10 includes an MCU (Microcontroller Unit) module, a positioning module 11, a first wireless connection module 14 and a key module 13. The positioning module 11 can be a GPS (Global Positioning System) module, a Beidou positioning module 11 or other modules with positioning function. Preferably, the positioning module 11 is a GPS module. In addition, the first terminal 10 can also be provided with modules such as a microphone, a display screen, and a camera according to actual needs.

[0037] The positioning module 11, the first wireless connection module 14, and the key module 13 are all electrically connected to the MCU module 12. The key module 13 can be a module with physical keys or a module with on-screen simulated keys. The drone module includes a drone 21, which is equipped with a control unit 22, a communication module 23, and a second wireless connection module 24. The drone 21, the communication module 23, and the second wireless connection module 24 are all electrically connected to the control unit 22.

[0038] Among them, the drone 21 includes a drone body and a main control module. The main control module is used to control the flight of the drone 21. The main control module is electrically connected to the control unit 22, so that data signals can be exchanged between the control unit 22 and the main control module. The control unit 22 can be a common microcomputer unit or single-chip microcomputer on the market or other modules with control functions.

[0039] The MCU module 12 and the control unit 22 are connected by a short-range wireless connection through the first wireless connection module 14 and the second wireless connection module 24, so that data transmission between the MCU module 12 and the control unit 22 is achieved based on the self-organizing network. Since the control unit 22 is carried by the drone 21, the control unit 22 can move with the drone 21, and the position of the control unit 22 is always kept within a reasonable distance from the position of the MCU module 12, so that the control unit 22 and the MCU module 12 can be stably wirelessly connected.

[0040] The control unit 22 establishes a long-distance communication connection with the second terminal 30 via the communication module 23, enabling data exchange between the control unit 22 and the second terminal 30. The first terminal 10 and the second terminal 30 establish a wireless connection via the MCU module 12, the first wireless connection module 14, the second wireless connection module 24, the control unit 22, and the communication module 23, enabling data exchange between the first terminal 10 and the second terminal 30, thereby maintaining communication between rescue personnel and the command center. The second terminal 30 can be a central console, computer, mobile phone, or the like in the command center.

[0041] Figure 2 This is a schematic diagram of the workflow of the working scenario of the first embodiment of the present invention. Figure 2In one application scenario, after rescuers discover a casualty with minor injuries, they input a first command to the MCU module via a keypad module. After receiving the first command, the MCU module obtains a first location parameter of a first terminal from the positioning module based on the first command and processes the first location parameter of the first terminal. The MCU module generates a first location parameter signal based on the first location parameter and transmits the first location parameter signal to a control unit via a first wireless connection module and a second wireless connection module. The control unit processes the first location parameter signal and generates a first location data signal based on the first location parameter signal. The first location data signal is then transmitted to a second terminal via a communication module. After the second terminal processes the first location data signal, it generates a first location coordinate based on the second location data signal. The command center uses the first location coordinates to determine the specific location of the casualty or rescuer and arranges for reinforcements to arrive at the corresponding location accurately and promptly to provide assistance to the casualty. Furthermore, after the rescuers send the command via the keypad module, they provide simple assistance to the casualty and then leave the casualty where they are. They then continue searching for and rescuing other casualties, allowing them to be found and rescued in a timely manner.

[0042] Figure 3 This is a workflow diagram of another working scenario of an embodiment of the present invention, please refer to Figure 3 In another application scenario, a rescuer is lost in a complex geographical environment or is themselves in danger. The rescuer inputs a second command to the MCU module via the key module. After receiving the second command, the MCU module obtains the second location parameter of the first terminal from the positioning module based on the second command. The MCU module processes the second location parameter of the second terminal and generates a second location parameter signal based on the second location parameter. The second location parameter signal is transmitted to the control unit via the first and second wireless connection modules. After processing the second location parameter signal, the control unit generates a second location data signal based on the second location parameter signal and transmits the second location data signal to the second terminal via the communication module. After processing the second location data signal, the second terminal generates second location coordinates based on the second location data signal. The command center obtains the specific location of the rescuer through the second location coordinates and arranges reinforcements to arrive at the corresponding location accurately and promptly to provide assistance to the rescuer and ensure their own safety.

[0043] Of course, in normal application scenarios, the MCU module, the first wireless connection module, the second wireless connection module, the control unit, and the communication module form a data transmission channel. Rescuers can also use other modules to receive or input data signals from this data transmission channel, such as inputting voice signals through a microphone, inputting video signals through a camera, receiving voice signals through a speaker, and receiving video signals through a display. Similarly, the command center can also receive or input voice signals, video signals, etc. from the data transmission channel through other modules. In this way, rescuers and the command center can communicate in real time, ensuring the smooth progress of rescue operations.

[0044] Compared to existing technologies, this embodiment can selectively and precisely locate the injured or rescuers based on the rescuer's actions, facilitating the command center's reinforcements to precisely reach the located location and provide on-site assistance or external rescue. This ensures that the injured or rescuers receive timely assistance, and allows rescuers to continue their search and rescue efforts after briefly treating the injured, greatly improving the effectiveness of the rescue.

[0045] In this embodiment, the first wireless connection module and the second wireless connection module are connected via WiFi, wherein the first wireless connection module is a WiFi module and the second wireless connection module is a wireless AP (Access Point) module. The wireless AP module provides a WiFi hotspot, and the WiFi module is wirelessly connected to the WiFi hotspot, thereby enabling the first wireless connection module and the second wireless connection module to achieve WiFi connection. In other embodiments, the first wireless connection module may be a wireless AP (Access Point) module, and the second wireless connection module may be a WiFi module. By adopting the WiFi connection method, a WiFi hotspot can be provided within a certain area, so that multiple first terminals can be connected at the same time, enabling multiple rescue personnel to contact the command center at the same time, improving communication efficiency, and thus improving rescue efficiency.

[0046] In this embodiment, the disaster relief site communication system further includes a signal strength detection module for detecting the strength of the WiFi signal. The signal strength detection module is electrically connected to the control unit.

[0047] In one application scenario, the signal strength detection module detects the strength of the wireless connection signal between the first wireless connection module 14 and the second wireless connection module. The wireless connection signal can be a WiFi signal. When the WiFi signal is below a threshold, it indicates that the WiFi signal at the rescuer's location is weak and there is a risk of disconnection at any time. The control unit sends a third instruction to the MCU module via the second wireless connection module and the first wireless connection module. Based on the third instruction, the MCU module obtains a third position parameter from the positioning module. The MCU module processes the third position parameter to generate a third position parameter signal and sends the third position parameter signal to the control unit via the first wireless connection module and the second wireless connection module 24. The control unit processes the third position parameter signal to generate a third position data signal and transmits the third position data signal to the second terminal via the communication module. The second terminal generates a third position coordinate based on the third position data signal. The command center records the third position coordinate and continues to contact the rescuer for a certain period of time. If the contact cannot be made, reinforcements are dispatched to the location corresponding to the third position coordinate to check the on-site situation. In this way, when rescuers are in danger and the wireless signal strength is weak, the rescuers' current situation can be learned in time, so that the rescuers can be rescued in time.

[0048] Figure 4 This is a workflow diagram of another working scenario of an embodiment of the present invention, please refer to Figure 4 In this embodiment, the control unit periodically sends a fourth instruction to the MCU module via the second wireless connection module and the first wireless connection module. For example, the control unit sends the fourth instruction at intervals of 5-10 minutes. After receiving the fourth instruction, the MCU module obtains a fourth position parameter from the positioning module based on the fourth instruction. The MCU module processes the fourth position parameter and generates a fourth position parameter signal based on the fourth position parameter. The MCU module sends the fourth position parameter signal to the control unit via the first wireless connection module and the second wireless connection module. The control unit processes the fourth position parameter signal and generates a fourth position data signal based on the fourth position parameter signal. The control unit transmits the fourth position data signal to the second terminal via the communication module. The second terminal generates fourth position coordinates based on the fourth position data signal and generates a movement trajectory map of the rescuer based on the fourth position coordinates. If a rescuer suddenly loses contact, the command center can locate the area where the rescuer last appeared based on the movement trajectory map and conduct a targeted search of that area. This can improve the efficiency and quality of the search and increase the success rate of finding the rescuer.
