[0046] The following is a detailed description of the implementation methods of the present application in conjunction with the accompanying drawings. The examples are provided only for illustrative purposes and cannot be understood as limiting the present application. The accompanying drawings are only for reference and illustration purposes and do not constitute a limitation on the scope of protection of the patent of the present application. Based on the examples in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0047] In order to solve the technical problems of the inability to transmit information in a timely manner and emergency warning and rescue when the network communication is unstable and people have difficulty calling for help, the embodiment of the present application provides a method for life safety monitoring and rescue, which achieves the purpose of providing safety warning and emergency rescue for people's life safety when the network communication is unstable.

[0048] See also Figure 1 In an embodiment of the present application, a method for life safety monitoring and rescue is provided, the method comprising:

[0049] S1. Within a preset distance range, obtain a neighbor terminal node with the same wireless network information as the target terminal node, form a network topology structure with the target terminal node and the neighbor terminal node through a dynamic self-organizing network protocol, obtain the location information of the target terminal node and the neighbor terminal node, and obtain the data transmission order based on the location information.

[0050] S2. Obtain environmental data, human vital signs data and image data of the location of the target terminal node, and make environmental safety judgments and life health judgments based on the environmental data, the human vital signs data and the image data to obtain environmental safety warnings and life health warnings.

[0051] S3. Based on the environmental safety warning and / or the life health warning, make an adaptability judgment on the living organism to obtain the living state of the living organism in the current environment.

[0052] S4. Formulate a rescue plan based on the living organism's current living state and the data transmission sequence. The rescue plan includes the time to send the rescue mission, the recipient of the rescue mission, the time required for each means of transportation, whether it is necessary to call an emergency number, and the transportation route.

[0053] The technical solution disclosed in the preferred embodiment of the present application is based on wireless ad hoc network technology to construct the network topology and transmit information. A wireless ad hoc network is a network composed of wireless devices, which can communicate directly with each other without the need for centralized infrastructure to transmit data. In a wireless ad hoc network, various devices can cooperate with each other to share information and resources by establishing temporary connections. A wireless ad hoc network is a centerless, multi-hop, self-organizing network composed of a group of mobile terminals with wireless transceivers, and is a mobile computer communication network. Compared with the traditional infrastructure model, a wireless ad hoc network has strong scalability, flexibility and self-organization. It can achieve a wireless communication network with wider coverage, larger capacity and stronger robustness through collaboration and routing selection between nodes without a central control node.

[0054] Each terminal node can be used as a target terminal node, and there are multiple neighboring terminal nodes distributed around each target terminal node. In a preferred embodiment of the present application, a distance range is pre-set according to the application scenario of the technical solution of the present application. The pre-set distance range should fully consider the data transmission rate of the wireless transceiver, the environmental scenarios used, such as towns, suburbs, rural areas and forests, etc. Different application scenarios should correspond to different preset distance ranges. For towns, they have the advantage of convenient transportation, but also the disadvantage of traffic congestion. The average distance that can be rescued in time in an urban environment is calculated through big data statistics, and it is used as the preset distance range for urban application scenarios. For the determination of the preset distance range, it can also be set according to different cities, so the user selects the environment in which he is located, or automatically obtains it through the terminal node, so that the terminal node selects a corresponding preset distance range.

[0055] Within a preset distance range, neighbor terminal nodes with the same wireless network information as the target terminal node are obtained. The selected neighbor terminal nodes and the target terminal node can communicate with each other through wireless ad hoc networking technology, and the target terminal node and the neighbor terminal nodes form a network topology structure through a dynamic ad hoc networking protocol. The network topology structure can be in various forms, such as chain topology, star topology, mesh topology, and hybrid topology.

[0056] Further, the location information of the target terminal node and the neighbor terminal node is obtained, and the data transmission order is obtained based on the location information. In the preferred embodiment of the present application, the data transmission is not freely selected from each neighbor terminal node of the network topology structure, but a targeted data transmission order is set according to the specific urban road traffic construction and the layout of the road where the target terminal node is located, such as Figure 2 As shown, the following steps are included:

[0057] S101, obtaining road conditions at locations where the target terminal node and the neighbor terminal node are located, and dividing the area where the neighbor terminal node is located into a first area, a second area, a third area, and a fourth area based on the road conditions with the target terminal node as the center.

[0058] For a region or a larger area, the road planning is interrelated and generally adopts the same road direction. In the preferred embodiment of the present application, the target terminal node is taken as the center, and the area where the neighbor terminal node is located is divided into the first area, the second area, the third area and the fourth area based on the road conditions. In the preferred embodiment of the present application, Figure 3 As shown, the following steps are included:

[0059] S1011. According to the road conditions, obtain the intersection closest to the target terminal node, and divide the road section intersecting the intersection into four areas by taking the average dividing line of the angle between two adjacent roads at the intersection as a dividing line.

[0060] S1012: translating the dividing line to the target terminal node, and dividing the area where the neighbor terminal node is located into a first area, a second area, a third area, and a fourth area.

[0061] like Figure 4 As shown in the figure, the nearest intersection is found around the target terminal node, and the intersection is used to represent the entire road distribution of the target terminal node. An intersection is generally formed by two roads intersecting each other. The two adjacent roads form an angle with the intersection as the center. The average line of the angle is used as the dividing line to divide the road section intersecting at the intersection into four areas.

[0062] The dividing line is translated to the target terminal node, and the area where the neighbor terminal node is located is divided into the first area, the second area, the third area, and the fourth area.

[0063] The dividing line obtained in the present application can divide the roads in the area where the neighbor terminal nodes around the target terminal node are located into four areas in different directions. For each area, it includes a relatively close main road. When selecting neighbor terminal nodes from four different areas, it can be ensured that the directions of the four main roads are all selected. The rescue personnel of the neighbor terminal nodes will not be delayed on the road due to road congestion, thereby ensuring the timeliness of the rescue.

[0064] S102. Based on the location information, calculate the distance between the neighbor terminal node and the target terminal node, sort the neighbor terminal nodes in the first area, the second area, the third area, and the fourth area from short to long according to the distance to the target terminal node, and divide them into the first echelon, the second echelon, and the third echelon for data transmission according to the sorting results.

[0065] In a preferred embodiment of the present application, after the area is reasonably divided, it is also necessary to fully consider the location of the neighbor terminal node, and calculate the distance from the neighbor terminal node to the target terminal node based on the location information of the target terminal node and the neighbor terminal node. Further, the first area, the second area, the third area and the fourth area are separate area ranges, and the neighbor terminal nodes in the first area, the second area, the third area and the fourth area are sorted from short to long according to the distance to the target terminal node. After the sorting is completed, it is evenly divided into the first echelon, the second echelon and the third echelon of data transmission. Among them, the neighbor terminal nodes of the first echelon are closer to the target terminal node, the neighbor terminal nodes of the second echelon are the second closest to the target terminal node, and the neighbor terminal nodes of the third echelon are relatively far away from the target terminal node.

[0066] The neighbor terminal nodes in each area are divided into echelons according to the distance. During data transmission, it can not only ensure the timely transmission of data, but also transmit relevant data to the neighbor terminal nodes in the second echelon when the neighbor terminal nodes in the first echelon cannot respond in time, so that there are neighbor terminal nodes in each of the four areas to respond, ensuring the reliability of data transmission.

[0067] Furthermore, in a preferred embodiment of the present application, the environmental data, human vital signs data and image data of the location of the target terminal node are obtained through the sensor of the target terminal node. The environmental data include oxygen content, temperature, humidity, carbon dioxide concentration and combustible gas concentration, etc., and the human vital signs data include heart rate, pulse, blood pressure, blood oxygen, body temperature and respiration, etc. The types of on-site environmental data and human vital signs data can be adjusted according to the different needs of the application scenario to ensure the availability of the acquired data.

[0068] For the acquired environmental data, human vital signs data and image data are used to make a comprehensive judgment on the on-site environment and vital signs. In the preferred embodiment of the present application, the on-site environment is judged based on the environmental data, and an environmental safety warning is performed. The method adopted is the threshold comparison method, and a threshold is set for each environmental data. When the corresponding threshold is exceeded, an environmental safety warning is performed. Correspondingly, based on the vital signs data, a life health warning is performed on the living body. The threshold comparison method can also be used, and a prediction model can also be used to perform a life health warning on the living body. Environmental safety warnings and life health warnings can be achieved through existing technologies, so they will not be repeated here.

[0069] Furthermore, when there is an environmental safety warning and / or a life health warning, it is necessary to make an adaptability judgment on the life form to obtain the survival status of the life form in the current environment. In a preferred embodiment of the present application, the survival status of the life form in the current environment is the time that the current environment can maintain the vital signs. Based on the changes in the environmental data and the human vital signs data within the first specific time period, the time that the current environment can maintain the vital signs is calculated. Figure 5 As shown, the following steps are included:

[0070] S301. Taking the time point when the environmental safety warning and / or the life health warning occurs as an end point, obtaining environmental data and human vital sign data within a first specific time period before the end point.

[0071] S302, constructing a vital sign maintenance time prediction model based on a neural network, and inputting environmental data and human vital sign data in a first specific time period before the endpoint into the vital sign maintenance time prediction model to obtain the time that vital signs can be maintained in the current environment.

[0072] In a preferred embodiment of the present application, the time point when the environmental safety warning and / or life health warning appears is taken as the end point, and the environmental data and human vital signs data in the first specific time period before the end point are obtained, and the above data are used to make an adaptability judgment on the life form, and the survival status of the life form in the current environment is obtained. Among them, the most important prediction result of the survival status of the life form in the current environment is the time that the vital signs can be maintained in the current environment. A life maintenance time prediction model is constructed based on a neural network. In this application, the structure and function of the neural network can be selected, trained and optimized according to the existing technology, which will not be repeated here.

[0073] Furthermore, after obtaining the survival status of the life form in the current environment, a rescue plan is formulated according to the survival status and the data transmission sequence in the current environment. The rescue plan includes the time to send the rescue task, the recipient of the rescue task, the time required for each transportation tool, whether it is necessary to call an emergency number, and the transportation route. In the preferred embodiment of the present application, a rescue plan is formulated according to the survival status and the data transmission sequence in the current environment, such as Figure 6 As shown, the following steps are included:

[0074] S401, determining whether the time for which vital signs can be maintained in the current environment is less than a threshold value, if so, calling an emergency number is required, if not, no calling an emergency number is required.

[0075] S402: According to the location and road conditions of the neighbor terminal node, traffic routes from the neighbor terminal node to the target terminal node are formulated in sequence, and the time required for each transportation tool is calculated.

[0076] S403: Based on the network topology, whether it is necessary to dial an emergency number, the traffic routes corresponding to the first-tier neighbor terminal nodes, and the time required for each transportation tool are sent to the corresponding first-tier neighbor terminal nodes.

[0077] S404. If the neighbor terminal nodes of the first echelon do not respond within the second specific time period, based on the network topology, the information on the need to make an emergency call, the traffic routes corresponding to the neighbor terminal nodes of the second echelon, and the time required for each means of transportation are sent to the corresponding neighbor terminal nodes of the second echelon.

[0078] S405. If the neighbor terminal node of the second echelon does not respond within the second specific time period, based on the network topology, the information that an emergency call needs to be made, the traffic routes corresponding to the neighbor terminal nodes of the third echelon, and the time required for each means of transportation are sent to the corresponding neighbor terminal nodes of the third echelon.

[0079] In the preferred embodiment of the present application, the contents of the rescue plan mainly include: the time of sending the rescue task, the recipient of the rescue task, the time required for each means of transportation, whether it is necessary to call an emergency number and the traffic route. The specific implementation of the rescue plan includes the following contents: first, based on whether the time that vital signs can be maintained in the current environment is less than the threshold, if so, it indicates that the person corresponding to the neighbor terminal node needs to call the 120 emergency number while performing relevant actual operations, if not, there is no need to call an emergency number. The target terminal node obtains the road conditions of the target terminal node through the map, and formulates a traffic route to the target terminal node for each neighbor terminal node based on the location information of the neighbor terminal node, and calculates the time required for different means of transportation, providing a basis for traffic selection for the neighbor terminal node.

[0080] Furthermore, based on the network topology, whether it is necessary to call an emergency number, the traffic routes corresponding to the first-tier neighbor terminal nodes, and the time required for each transportation tool are sent to the corresponding first-tier neighbor terminal nodes. The first-tier neighbor terminal nodes include the first area, the second area, the third area, and the fourth area. Therefore, the personnel corresponding to the first-tier neighbor terminal nodes are distributed in the area closest to the four main roads, and can rush to the location of the target terminal node in time from different directions, thereby improving the efficiency of rescue.

[0081] When receiving a rescue mission, the personnel corresponding to the first-tier neighbor terminal node make corresponding choices based on whether to call an emergency number, the recommended transportation route, and the time required for each transportation tool, and send the response information to the target terminal node at the same time. If the target terminal node does not receive the response information from the first-tier neighbor terminal node in a certain area within the second specific time period, it indicates that the first-tier neighbor terminal node in the area did not respond in time, and the rescue mission needs to be sent to the second-tier neighbor terminal node in the area.

[0082] Similarly, when receiving a rescue mission, the personnel corresponding to the neighbor terminal node of the second echelon make corresponding choices based on whether to call an emergency number, the recommended transportation route, and the time required for each transportation tool, and send the response information to the target terminal node at the same time. If the target terminal node does not receive the response information of the neighbor terminal node of the second echelon in a certain area within the second specific time period, it indicates that the neighbor terminal node of the second echelon in the area has not responded in time, and the rescue mission needs to be sent to the neighbor terminal node of the third echelon in the area.

[0083] The method of life safety monitoring and rescue proposed in the embodiment of the present application is based on the construction of network topology and information transmission of wireless ad hoc network technology. The target terminal node and the neighbor terminal node form a network topology through a dynamic ad hoc network protocol, and further divide the area where the neighbor terminal node is located into the first area, the second area, the third area and the fourth area extending in four different directions based on the traffic distribution of the target terminal node, so as to avoid rescue personnel being delayed by congestion and ensure the timeliness of rescue. In addition, the neighbor terminal nodes in each area are divided into the first echelon, the second echelon and the third echelon, and the rescue personnel participate in the rescue in batches to save human resources. Environmental safety warning is carried out for the on-site environment and life health warning is carried out for the life body to avoid blind rescue by the rescue personnel, and the environmental data and vital signs data are further combined to judge the survival status of the life body in the current environment, so as to formulate a more targeted rescue plan to improve the success rate of rescue.

[0084] Accordingly, if Figure 7 As shown, according to the life safety monitoring and rescue method, an embodiment of the present invention also provides a life safety monitoring and rescue system, the system comprising: a data transmission sequence formulation module 1, an environment and life warning module 2, a survival status judgment module 3 and a rescue plan formulation module 4;

[0086] The environment and life warning module 2 is used to obtain the environmental data, human vital signs data and image data of the location of the target terminal node, and perform environmental safety judgment and life health judgment based on the environmental data, the human vital signs data and the image data to obtain environmental safety warning and life health warning.

[0087] The survival status judgment module 3 is used to judge the adaptability of the living body based on the environmental safety warning and / or the life health warning, and obtain the survival status of the living body in the current environment.

[0088] The rescue plan formulation module 4 is used to formulate a rescue plan according to the survival status of the living organism in the current environment and the data transmission order. The rescue plan includes the rescue task sending time, the rescue task recipient, the time required for each means of transportation, whether it is necessary to call an emergency number and the transportation route.
