Description

Technical Field

[0001] The present application relates to the field of emergency rescue technology, and in particular to an emergency rescue method, system, equipment and storage medium. Background Art

[0002] Satellite navigation and positioning technology is currently widely used in search and rescue operations in remote areas such as deserts, mountains, and oceans. When responding to major disasters such as earthquakes and floods, the effectiveness of rescue efforts depends crucially on the timely acquisition of disaster information and the rapid deployment of rescue forces. Currently, mainstream satellite navigation and positioning systems include the Global Positioning System (GPS) and the Beidou Satellite Navigation System (BDS). However, existing technologies have significant limitations: while GPS positioning devices can achieve rapid and accurate positioning, they only provide one-way navigation and are unable to establish communication links. In offshore rescue scenarios, even if the coordinates of a person in distress can be determined using GPS signals, the inability to transmit this location information back to the command center makes it difficult for both rescuers and the rescue team to establish effective communication. The command center is unable to obtain the specific location of the person in distress in real time, seriously impacting rescue efficiency.

[0003] There are three major problems with the existing search and rescue model: first, in a state of complete loss of contact, only blind search can be adopted, which not only has a low success rate but also consumes a lot of social resources; second, most emergency rescue equipment is only designed for professional rescue personnel and is not widely used in civilian use; third, although existing personal emergency equipment has two-way communication functions, it has technical bottlenecks such as high power consumption and short battery life, which seriously restricts the actual effectiveness of satellite navigation in emergency rescue, and ultimately leads to low overall search and rescue efficiency.

The terms (such as those defined in generally used dictionaries) will be interpreted as having the same meaning as in the context of the relevant technical field and will not be interpreted as having an idealized meaning or an overly formal meaning unless clearly defined in the various embodiments of the present application.

[0022] The following describes some embodiments of the present application in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments may be combined with each other.

[0023] In order to improve the efficiency of emergency rescue and reduce resource investment, this application proposes an emergency rescue method, system, device and storage medium. When implementing this emergency rescue method, the mobile terminal 200 carried by the lost person needs to be equipped with a Beidou chip with a Beidou emergency information receiving function, so that in the absence of a public network, the rescue information sent by the Beidou satellite can be received, thereby allowing the lost person to know in a timely manner that someone outside is searching for him or her, thereby enhancing the confidence of the lost person. In addition, the lost person can also move to the rescue point location specified by the rescue information according to the received rescue information, thereby achieving the purpose of improving rescue efficiency. Furthermore, in the present application, an unmanned aerial device 300 is combined in the rescue process. After the rescue range is determined, the unmanned aerial device 300 flies within the rescue range and provides communication network signals. Then, when the unmanned aerial device 300 flies to an area close to the lost person (that is, when the mobile terminal 200 of the lost person can receive the network signal provided by the unmanned aerial device), the mobile terminal 200 of the lost person can send information to the outside through the communication network signal, thereby further enhancing the confidence of the lost person in being successfully rescued, and based on the information interaction between the lost person and the rescue center platform 100 through the mobile terminal 200, rescue can be achieved faster.

[0024] The mobile terminal 200 involved in the embodiments of the present application may include various handheld devices (mobile phones, iPads, etc.) or wearable devices (watches, bracelets, etc.) with communication functions, as well as various forms of user equipment (UE), etc. For ease of description, the above-mentioned devices are collectively referred to as mobile terminal 200.

[0025] The emergency rescue system is described below with reference to some specific embodiments.

[0026] Figure 1 FIG2 is a schematic diagram showing a structure of an emergency rescue system according to an embodiment of the present application. Schematically, the system includes: a rescue center platform 100, a mobile terminal 200 carried by a missing person, and an unmanned aerial vehicle 300.

[0027] Mobile terminal 200 is equipped with a Beidou chip capable of receiving Beidou emergency information. The Beidou chip can be integrated into a user identification card, enabling the missing person's mobile terminal 200 to support Beidou satellite navigation and positioning, as well as emergency communication functions. This allows the missing person's mobile terminal 200 to not only support traditional mobile communication functions but also integrate the capabilities of the Beidou chip, enabling positioning, timing, and emergency information reception.

[0028] Among them, the Subscriber Identity Module (SIM) card is an IC card held by mobile users of mobile communication systems such as GSM. It is also called a subscriber identification card. GSM and other mobile communication systems use SIM cards to identify GSM users. The same SIM card can be used in different mobile phones. A GSM phone can only access the network after inserting a SIM card. The SIM card is an essential component for a GSM phone to access the GSM network. Once the SIM card is removed from the phone, the phone will not be able to access various services provided by the network operator, except for emergency calls. In addition to serving as a key, the SIM card also provides many user conveniences. Users can simply insert or embed the SIM card into any GSM terminal to establish communications. The SIM card also manages many information required for user services and can be used to store short messages, particularly those received when the user's phone is turned off or away.

[0029] The UAV 300 may be a drone equipped with a communication relay device or a network hotspot, thereby serving as a temporary communication node. While flying over the rescue area, the UAV provides real-time communication network signals. When the UAV approaches the area where the missing person is, it can provide the communication network signals to the mobile terminal, enabling the missing person's mobile terminal 200 to communicate with the rescue center platform 100 via the detected communication network signals.

[0030] During emergency rescue, if Figure 2 As shown, the rescue process includes steps S100 to S500: Step S100 , in response to an emergency rescue instruction, a rescue plan is generated according to the travel information of the missing person carrying the mobile terminal 200 .

[0031] The rescue center platform 100 executes this step. The emergency rescue command can be a rescue command automatically generated by the rescue center platform 100. For example, in mountain rescue or ocean rescue situations, each missing person carries a mobile terminal 200. The missing person can use their mobile terminal 200 to send information to the rescue center platform 100 in real time or at preset intervals, allowing the rescue center platform 100 to determine whether the missing person is currently safe. If no information is received from the mobile terminal 200 carried by the missing person within the preset interval, the missing person is determined to be missing, and an emergency rescue command is generated. Alternatively, when a user is outdoors and encounters an abnormal situation (such as a harsh environment), the user can proactively send a rescue message to the rescue center platform 100. Alternatively, the rescue command can be generated based on a rescue request received from a third party.

[0032] After the rescue center platform 100 receives the emergency rescue instruction, it first determines the mobile terminal 200 carried by the missing person based on the identity of the missing person, and obtains the travel information of the missing person based on the mobile terminal 200. The travel information can be obtained in the following ways, but is not limited to: First, the mobile terminal 200 of the missing person is equipped with a user identification card with an integrated Beidou chip. When the mobile terminal 200 is in normal working state, it can upload time information, location information and other sensor data to the background server in real time. After determining the mobile terminal 200 of the missing person, the rescue center platform 100 can obtain the travel information of the missing person through the background server; Second, if the missing person is using a smartphone that supports Beidou function, the operator can obtain the time and approximate location of the missing person's last connection to the base station through base station positioning technology. Within the coverage area of ​​the public network, the operator can also transmit data in real time through the cellular network or other communication protocols; Third, when an emergency occurs, the mobile terminal 200 of the missing person automatically triggers an alarm mechanism and sends the stored travel information to the emergency rescue platform.

[0033] The travel information includes but is not limited to the mode of transportation, the last received location and / or time of loss of contact sent by the mobile terminal 200 of the missing person.

[0034] The rescue plan includes a rescue scope and rescue information, and the rescue information includes the location information of at least one rescue point within the rescue scope. The rescue information is information sent by the emergency rescue platform to the mobile terminal 200 of the missing person via the Beidou satellite.

[0035] In some embodiments, as Figure 3 As shown, a rescue plan is generated according to the travel information of the missing person carrying the mobile terminal 200, including steps S110 to S120: Step S110: Determine a rescue range based on the location, time of loss of connection, and / or mode of transportation, and determine at least one rescue route based on the rescue range and the map.

[0036] Exemplarily, after obtaining the user's travel information, the travel information includes at least the last location and time of loss of contact of the missing person before the loss of contact, and may also include transportation information.

[0037] If the travel information obtained only includes the location and time of loss of contact, the maximum distance the missing person could have traveled is determined based on the time difference between the time of loss of contact and the current time, combined with the location of loss of contact. It can be understood that after calculating the time difference (i.e., the period of loss of contact) based on the time of loss of contact and the current time, and knowing the location of loss of contact, it is possible to infer the maximum distance the missing person could have traveled from the location of loss of contact to the current time. A circle can then be constructed with the location of loss of contact as the center and the maximum distance as the radius to determine the rescue range.

[0038] If the travel information obtained includes the location of loss of contact, time of loss of contact, and mode of transportation, then similarly, the maximum distance the missing person could have traveled can be determined based on the time difference between the time of loss of contact and the current time, combined with the location of loss of contact and mode of transportation. It can be understood that after calculating the time difference between the time of loss of contact and the current time, and also knowing the location of loss of contact and mode of transportation, it is possible to more accurately infer the maximum distance the missing person could have traveled from the location of loss of contact to the current time. Then, a circular area can be constructed with the location of loss of contact as the center and the maximum distance as the radius to determine the rescue range.

[0039] After determining the rescue scope, the road that the missing person may travel can be inferred in combination with the map, and then at least one rescue path can be determined based on the road that the missing person may travel. Among them, the rescue path includes the rescue path of the drone and the rescue path of the rescuers. For the rescue path of the rescuers, it can be determined based on the road that the missing person may travel that the rescuers mainly conduct search and rescue activities on. For the rescue path of the drone, it can be to evenly set up multiple drone rescue paths above the rescue scope, and let the drone fly in the sky for search and rescue. According to the above method, the rescue plan and rescue force can be planned in a coordinated manner to achieve precise rescue, reduce the cost of rescue resources, and improve rescue efficiency.

[0040] Step S120: Determine rescue information including locations of several rescue points based on the rescue route.

[0041] Since there are rescuers along each rescue route, and at least one rescue point is set up, after the rescue route is determined, rescue information can be determined based on the rescue route. The rescue information includes but is not limited to the location of the rescue point, the rescue method, and guidance directions (used to inform the missing person which direction to go). As for the rescue method, it can be used to inform the missing person of the rescue method we have adopted, such as search and rescue personnel using drones for rescue.

[0042] Step S200: broadcast rescue information to mobile terminals 200 within the rescue range via Beidou satellites.

[0043] Step S300: receiving rescue information sent by the rescue center platform 100 via Beidou satellite.

[0044] Step S400: Display the current device location information and rescue point location information to guide the missing person to move toward the rescue point.

[0045] After determining the rescue information in step S100, the rescue center platform 100 can broadcast the rescue information to the mobile terminals 200 within the rescue range via the Beidou satellite. The rescue information can be broadcast to all mobile terminals 200 within the rescue range, or only to the mobile terminal 200 of the missing person.

[0046] After the missing person receives the rescue information via mobile terminal 200, they know that someone outside is aware of their loss and is searching for them, which can boost their confidence. Furthermore, the missing person's mobile terminal 200 is integrated with a Beidou chip, allowing the missing person's mobile terminal 200 to locate itself using Beidou satellites, or even satellite-based PPP positioning, achieving high positioning accuracy. After receiving the location information of the rescue point, the missing person can use the positioning indicator module in mobile terminal 200 to determine the distance between the current device location and the rescue point. The positioning indicator module can display the distance to the rescue point when in motion. For example, the positioning indicator module can be a built-in map. If this is a built-in map, after receiving the location information of the rescue point, the missing person can use the built-in map in mobile terminal 200 to move toward the rescue point. This embodiment, by sending rescue information to the missing person's mobile terminal 200, not only boosts the missing person's confidence in being rescued, but also improves the efficiency of rescue efforts.

[0047] It should be noted that the rescue information is information generated by the rescue center platform 100 and needs to be broadcast via Beidou satellites, and the rescue information complies with the format required by the Beidou ICD specification.

[0048] Rescue information injection (uplink) can optionally follow the BeiDou-3 signal system, so the rescue information is injected from the ground to the satellite, using reserved fields to carry the rescue information; the "injection platform" design technically supports receiving injection information from specific departments (such as the Ministry of Emergency Management, the Ministry of Transport, etc.) through an application interface (data security issues need to be considered separately, and relevant data authentication technologies must be adopted as required).

[0049] Rescue information broadcast (downlink): The Beidou satellite broadcasts the aforementioned injected "Beidou rescue information"; as needed, the area where the rescue information is broadcast can be controlled by controlling the specific satellite number that broadcasts the information; as needed, the broadcast time period, frequency, etc. can also be controlled (no need for 24-hour broadcast); as needed, on-demand (for individuals, distinguished by mobile phone numbers), regional broadcast, etc. can also be achieved (the regional radius can be set to 1km, 10km, 30km, 50km, 100km, etc.).

[0050] Step S500 , controls no more than a preset number of UAVs 300 to search and fly within the rescue range, and provides a communication network signal through the UAVs 300 so that the missing person can exchange information with the rescue center platform 100 through the mobile terminal 200 .

[0051] It should be noted that there is no fixed execution order for step S500 of this embodiment and the above-mentioned steps S200 , S300 , and S400 .

[0052] After the rescue plan and the rescue path of the UAV 300 are determined, the rescue center platform 100 can control multiple UAVs 300 to fly along the rescue path of the UAV 300. During the flight, if the UAV 300 reaches an area where the mobile terminal 200 of the missing person can receive the communication network signal provided by the UAV 300, the mobile terminal 200 of the missing person can achieve network connection through the communication network signal and then send information to the outside world. This allows information exchange between the mobile terminal 200 and the rescue center platform 100, thereby further improving the efficiency of the rescue.

[0053] Exemplarily, after the missing person receives the rescue information sent by the rescue center platform 100 through the mobile terminal 200, if the communication network signal provided by the unmanned aerial device 300 can be used to send information outward, the missing person can send his or her current environment and situation to the rescue center platform 100 through the mobile terminal 200. When the rescue center platform 100 determines that the missing person can be temporarily connected to the Internet, it can know which unmanned aerial device 300 is used to connect to the Internet, and thus determine the approximate location of the missing person. The rescue center platform 100 can then adjust the rescue plan based on the missing person's own situation and current approximate location, for example, adjust the rescue point location, adjust the rescue route, etc., so that the rescue operation is more targeted and the probability and efficiency of successful rescue are improved. It can be understood that when the mobile terminal 200 of the lost person can be temporarily connected to the Internet through the communication network signal, the lost person can exchange information with the rescue center platform 100 in real time through the mobile terminal 200, so as to enhance the confidence of the lost person in being rescued, and through the interaction of information, the lost person can reach the rescue point or a safe location more quickly.

[0054] In addition, after receiving the information sent by the mobile terminal 200, the rescue center platform 100 determines which unmanned aerial vehicle 300 the missing person is near, and can control the remaining unmanned aerial vehicles 300 to withdraw, thereby saving resources of the unmanned aerial vehicles 300.

[0055] In some embodiments, when performing rescue using the UAV 300 , the process further includes: controlling the UAV 300 to collect on-site images in real time, and adjusting the rescue plan based on the collected on-site images.

[0056] It is understood that when the UAV 300 is flying over the rescue range, it can use the equipped camera or infrared imaging equipment to collect real-time on-site images within the rescue range. The images can be video images or static images. By analyzing the on-site images, if a target suspected of being a missing person is found (such as a human outline, signs of activity, etc.), its specific location can be confirmed through image recognition technology. In addition, the on-site images can also help understand the terrain features (such as mountains, rivers, forests, etc.) and possible obstacles (such as landslide areas, deep trenches, etc.) within the rescue range. For example, if the image shows a predetermined rescue route, If there are landslides or accumulated water on the path, the rescue route can be immediately adjusted and a message can be sent via Beidou satellite to inform the missing person to avoid the dangerous area. Furthermore, the on-site imagery can also reflect the current weather conditions (such as heavy rain or dense fog) or environmental conditions (such as fire smoke or flooding). This information helps determine whether the rescue plan needs to be changed (such as suspending certain high-risk operations or strengthening protective measures). Furthermore, the on-site imagery may also capture other valuable clues, such as markings left by the missing person (such as flags or reflective objects) and available temporary shelters or supply points (such as buildings or water sources) nearby. Based on this information, the rescue plan can be adaptively adjusted to improve rescue efficiency.

[0057] Adjustments to the rescue plan include but are not limited to re-determining the specific location of the missing person. If the exact location of the missing person is locked through the image, the rescue scope and path can be directly updated. For example, if the missing person was originally thought to be in area A, but was found to be in area B through the image, the deployment direction of the drone and rescue team can be quickly adjusted; the rescue path can be optimized, and a safer and faster rescue route can be selected based on the terrain and obstacle information in the image. For example, if the image shows that a mountain road has been blocked by a mudslide, another detour can be taken; the allocation of rescue forces can be adjusted. If the image shows that the missing person is in a relatively isolated or difficult to reach area, If the missing person is found in an area with a high visibility, more drones or professional search and rescue teams can be dispatched for support. Conversely, if it is confirmed that the missing person is close to a rescue point, unnecessary resource investment can be reduced. Targeted rescue measures can be formulated, and appropriate response measures can be taken according to the weather and environmental information reflected in the image. For example, if thick fog is found at the scene that affects vision, lighting equipment can be added. If there is a threat of flooding, lifeboats or ropes and other tools can be prepared. More accurate guidance information can be provided, and the analyzed image results can be converted into specific guidance for the missing person, such as telling the missing person which direction to go to more easily find a rescue point, or reminding them to avoid dangerous areas.

[0058] In this embodiment, when someone is lost, a rescue plan is determined based on the travel information of the lost person carrying a mobile terminal 200. Since the mobile terminal 200 is equipped with a Beidou chip with Beidou emergency information reception function, it can receive information sent by the rescue center platform 100 via Beidou satellites even in the absence of a public network. After determining the rescue range, the rescue center platform 100 can broadcast rescue information via Beidou satellites to mobile terminals 200 within the rescue range. When the lost person receives the rescue information through the mobile terminal 200 they carry, they can clearly know that someone is searching for them, thereby increasing their confidence in being rescued and reducing their panic. In addition, the rescue information includes rescue point location information. Therefore, based on the rescue point location information and the built-in map, the mobile terminal 200 can guide the lost person to the rescue point, thereby improving the efficiency of the rescue. Furthermore, the present embodiment incorporates an unmanned aerial device 300, and when the unmanned aerial device 300 flies over the rescue range, it will provide a communication network signal in real time. When the unmanned aerial device 300 flies to an area where the mobile terminal 200 of the missing person can connect to the communication network signal, the mobile terminal 200 of the missing person can exchange information with the rescue center platform 100 through the communication network signal.
