[0060] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0061] like Figure 1 As shown, a system for marking the injury of a wounded person at a rescue site, the system comprising: an analysis terminal, at least one rescue terminal and at least one wounded person terminal;

[0062] When the rescue terminal responds to the rescue mission, it obtains a wounded terminal and binds it to the wounded as the target wounded terminal; the rescuer triggers the communication connection between the rescue terminal and the target wounded terminal through a preset trigger command;

[0063] After receiving the connection signal fed back by the target injured terminal, the rescue terminal obtains the injury information and the device information of the target injured terminal, and uploads it to the corresponding analysis terminal; the rescue terminal also enters the injury information into the target injured terminal;

[0064] The analysis terminal confirms the severity of the injury based on the rescue mission and injury information, and sends the severity of the injury to the target injured terminal through the rescue terminal;

[0065] After receiving the severity of the injury, the target injured terminal displays the severity of the injury in a preset manner.

[0066] The specific implementation process of this embodiment includes:

[0067] In this embodiment, the analysis terminal includes a local server and a cloud server; wherein the local server is set at the rescue site and communicates with the rescue terminal in the rescue site; it is applicable to the rescue site where the remote communication is limited. The cloud server is applicable to the rescue site where the remote communication is not limited. It depends on the situation of the rescue site.

[0068] In this embodiment, there are many rescue sites, such as earthquake rescue sites, chemical plant rescue sites, nuclear leak rescue sites, etc. Each rescue site has certain differences in the angle of injury to the injured, which leads to different rescue contents at each rescue site, and the rescue terminal also has different inspection contents for the injuries of the injured at the rescue site. Therefore, before the rescue terminal enters the rescue site, the analysis terminal sends the corresponding rescue task to each rescue terminal, so that the rescue personnel can mark the injuries of the injured according to the rescue task, making the injury marking of the injured more accurate.

[0069] In this embodiment, there is at least one rescuer at the rescue site. Each rescuer is equipped with a rescue terminal; each rescuer carries at least one injured terminal; the rescuer binds the injured terminal to the injured during the rescue mission. In this embodiment, the binding of the injured terminal to the injured includes fixing the injured terminal to several body parts of the injured through a fixing device, and associating the device information of the injured terminal with the identity information of the injured. Among them, the fixing device includes a rubber belt with a quick-release structure, and the several body parts include wrists and ankles.

[0070] In this embodiment, after binding the wounded terminal to the wounded, the rescuer confirms that the wounded terminal is the target wounded terminal; then the rescue terminal is triggered to communicate with the target wounded terminal through a preset trigger instruction; the preset trigger instruction includes an action instruction and a voice instruction. Among them, the action instruction includes clicking the preset position of the rescue terminal several times in a row. It should be noted that before triggering the rescue terminal, the rescuer should turn on the communication device of the target wounded terminal, and then communicate with the target wounded terminal by triggering the rescue terminal. In this embodiment, the connection method between the rescue terminal and the target wounded terminal includes a wireless connection method such as Bluetooth connection; in some other embodiments, the rescue terminal and the target wounded terminal are wired through a cable, and the rescue terminal and the target wounded terminal are both provided with the same data interface for wired connection of the cable. The advantage of the wired connection is that the transmission is stable and is not affected by other rescue terminals and target wounded terminals. For rescue scenarios with strong radiation such as nuclear leaks, wired connections can solve the problem of communication failure caused by radiation affecting communication equipment.

[0071] It should be noted that in strong radiation scenarios such as nuclear leakage, when communication between the rescue terminal and the analysis terminal is blocked, you can choose to manually assess the severity of the injury and enter the severity of the injury together with the injury information into the target injured person's terminal.

[0072] In this embodiment, the rescue terminal and the target injured terminal communicate with each other, so that the rescue terminal can enter the injury information and injury severity into the target injured terminal to complete the injury marking of the injured; the problem of manual handwriting easily causing the emergency injured classification card to be contaminated is avoided. By analyzing the injury information according to the rescue mission, the analysis terminal can more accurately assess the severity of the injured's injury, reduce the workload of rescue personnel, and improve the accuracy of injury marking. The technical problems of low efficiency of injury marking and information transmission at the rescue site in the prior art are solved.

[0073] According to another embodiment of the present invention, the injury information includes vital sign parameters; Figure 2 As shown, the casualty terminal includes:

[0074] A communication module is used to communicate with the rescue terminal and feedback the connection signal;

[0075] The detection module is used to detect the vital signs parameters of the injured, including blood oxygen data, blood pressure data and heart rate data;

[0076] A storage module is used to store the vital sign parameters and injury severity of the injured person;

[0077] A display module, used to display the severity of the injury in a preset display mode;

[0078] The wake-up module is used to respond to a preset wake-up action to wake up the communication module for communication connection with the rescue terminal, and wake up the detection module to detect the injured; the preset wake-up actions include clicking, sliding and shaking.

[0079] The specific implementation process of this embodiment includes:

[0080] In this embodiment, the detection module includes a blood oxygen sensor, a blood pressure sensor and a heart rate sensor, which respectively detect the blood oxygen data, blood pressure data and heart rate data of the injured person.

[0081] In this embodiment, the display module includes a plurality of LED lights, and the severity of different injuries of the injured person is indicated by controlling the number of LED lights that light up or the color of the LED lights.

[0082] In some other embodiments, the display module further includes a visualization screen, which indicates the severity of the injury of the injured person by displaying different numbers or symbols on the visualization screen.

[0083] In this embodiment, the wake-up module includes an acceleration sensor, which is used to identify the swinging action; before the rescuer fixes the injured terminal to the injured person's body, the rescuer swings the injured terminal so that the acceleration sensor can recognize it, thereby waking up the detection module and the communication module.

[0084] The wake-up module also includes a pressure sensor, which is used to identify click actions and sliding actions; before the rescuer fixes the injured terminal to a part of the injured person's body, he clicks or slides at a preset position of the injured terminal so that the pressure sensor can recognize it, thereby waking up the detection module and the communication module.

[0085] It should be noted that, in this embodiment, after the target injured person terminal is connected to the rescue terminal, the target injured person terminal does not actively disconnect from the rescue terminal.

[0086] In this embodiment, the wake-up module is set to respond to the preset wake-up action to wake up the detection module and the communication module, which is simple and easy to operate and suitable for the complex environment of the rescue site. In particular, when the rescuers are wearing protective clothing, protective gloves and other protective equipment, the detection module can be quickly awakened to detect the injured, and the communication module can be used to communicate with the rescue equipment. The efficiency of injury marking during the rescue process is improved.

[0087] According to another embodiment of the present invention, the injury information includes an injury information table; Figure 3 As shown, the rescue terminal includes:

[0088] The information table confirmation module is used to confirm the injury information table according to the rescue mission; the injury information table includes several injury examination items and the confirmation order of the injury examination items;

[0089] The information form filling module is used to display the injury examination items in the confirmed order so that the rescuers can fill them out after checking;

[0090] A communication module, used for communication connection with the analysis terminal and communication connection with the wounded terminal;

[0091] A trigger module is used to generate a plurality of trigger signals in response to a preset trigger instruction, and send the plurality of trigger signals to the communication module, the information table confirmation module and the information table filling module in a one-to-one correspondence, so that the communication module is connected to the analysis terminal or the injured terminal for communication, the information table confirmation module confirms the injury information table, and the information table filling module displays the injury examination items in sequence according to the confirmation order;

[0092] The preset trigger instructions include voice instructions and action instructions.

[0093] The specific implementation process of this embodiment includes:

[0094] In this embodiment, rescuers need to manually check multiple aspects of the injured person when performing rescue tasks and fill in the injury information form; in this embodiment, different rescue tasks correspond to different injury inspection items, and in this embodiment, the rescue terminal pre-stores multiple injury information forms corresponding to multiple rescue tasks. Different rescue tasks correspond to different injury inspection items, and a confirmation order is pre-set between multiple inspection items corresponding to the same rescue task.

[0095] In this embodiment, by setting the confirmation order of the injury examination items and displaying the injury examination items in sequence according to the confirmation order through the information form filling module, it is possible to avoid rescuers from missing items and improve the efficiency of rescuers during the inspection.

[0096] In this embodiment, the information form filling module includes:

[0097] The voice broadcast unit is used to broadcast the injury examination items in sequence according to the confirmation order, so as to prompt the rescue personnel to check and confirm the injured person in the confirmed order;

[0098] A data collection unit is used to obtain the on-site voice data of rescuers after each injury examination item is broadcast;

[0099] The information extraction unit is used to extract keywords from the on-site voice data after the injury examination items are broadcast, obtain the examination results of the injury examination items and enter them into the injury information table.

[0100] In this embodiment, the voice broadcast unit broadcasts the injury examination items in sequence according to the confirmation order, and each injury examination item is set with a corresponding item inspection time. During the item inspection time after the injury examination item is broadcasted, the data collection unit collects the on-site voice data of the rescue personnel;

[0101] In some embodiments, the injury examination project also needs to collect image data of the injured person. For example, in a nuclear leak rescue scenario, it is necessary to obtain an image of the injured person's body skin. Therefore, when an injury examination project requires image data of the injured person, after the voice broadcast unit broadcasts the injury examination project, the data collection unit responds to the voice instructions of the rescue personnel to collect the image data of the injured person and enter it into the injury information table; in this embodiment, the image data includes facial images, and images of several feature positions corresponding to the rescue mission.

[0102] In this embodiment, the analysis terminal also analyzes the image data of the injured person to obtain feature information, including:

[0103] Obtain the identity information of the injured person based on the face image; record the identity information of the injured person, and associate the identity information of the injured person with the target injured person terminal;

[0104] By recognizing the facial image of the injured, the identity information of the injured can be verified. The management personnel at the rescue site can make real-time adjustments to the rescue work at the rescue site based on the identity information of the injured after the injury is marked. For example, in an earthquake rescue site, the identity information of the injured needs to be verified in real time. The analysis terminal obtains the identity information by recognizing the facial image of the data acquisition unit, which can greatly reduce the workload of manually verifying the identity of the injured.

[0105] According to the image of each characteristic position of the rescue mission, the inspection results of the corresponding injury inspection items are obtained.

[0106] In this embodiment, the characteristic positions include the neck, chest, and fingers, etc. The injury inspection items of each rescue mission are pre-set with inspection requirements, and the analysis terminal identifies the image of the characteristic position according to the inspection requirements and obtains the inspection result.

[0107] For example, in a nuclear leak or chemical plant explosion scenario, it is necessary to collect several skin images of the injured. Inspection requirements include identifying the skin color of the injured and the number and area of ​​feature points per unit skin area. Feature points include rashes, plaques, etc.

[0108] The data acquisition unit collects the image data of the injured, avoiding the problem of inaccurate injury examination items of the injured due to the rescuers' vision being blocked by wearing protective equipment.

[0109] According to another embodiment of the present invention, the analysis terminal includes:

[0110] A model storage module is used to store a number of injury analysis models; the number of injury analysis models are associated with a number of rescue tasks in a one-to-one correspondence;
