Description

Technical Field

[0001] This invention belongs to the field of medical auxiliary technology, specifically relating to a rapid rescue device and its control method, as well as a combined rescue control method. Background Technology

[0002] After a traffic accident on a highway, a large number of vehicles often cause a traffic jam, making it difficult for ambulances to reach the scene. Emergency personnel must then carry stretchers and medical equipment, wasting valuable time and reducing rescue efficiency. To address this, CN202210450933.5 discloses a highway rapid rescue vehicle. This vehicle has a hydraulic lifting system at the bottom of its cargo box body, connecting a drive wheel set and a steering wheel set. The drive wheel set enables the vehicle to move as a whole, the steering wheel set enables turning, and the hydraulic lifting system allows the cargo box body to be raised to overcome obstacles, allowing the vehicle to continue moving forward. This solves the problem of traffic congestion affecting the timeliness of rescue in existing technologies.

[0003] The aforementioned patent discloses that the rescue vehicle is raised to overcome obstacles, which means that the width of the rescue vehicle needs to be greater than that of the obstacles on the road. This results in a larger overall size of the rescue vehicle and poor maneuverability. In particular, during traffic jams, the obstacles are not arranged in a straight line but are staggered, which increases the difficulty for the rescue vehicle with poor maneuverability to move in the traffic jam and reduces its passage speed. Summary of the Invention

[0004] The present invention aims to solve the technical problems existing in the prior art. The first objective of the present invention is to provide a rapid rescue device. The second objective of the present invention is to improve a control method based on the aforementioned rapid rescue device. The third objective of the present invention is to provide a joint rescue control method based on the rapid rescue device and an ambulance.

[0005] To achieve the first objective mentioned above, the present invention adopts the following technical solution: a rapid rescue device, comprising a carrying platform, four support legs located at the bottom of the carrying platform for supporting it, running wheels located at the bottom of each support leg for ground operation, and a protective device installed on the carrying platform for limiting and protecting the injured person; the front end of the carrying platform is provided with an image detection device for detecting obstacles and a distance detection device for detecting the distance between the front end of the carrying platform and obstacles, the signal output terminals of the image detection device and the distance detection device are connected to the vehicle controller, the vehicle controller obtains the distance between two parallel vehicles in traffic jams; the four support legs are located on the left and right sides of the carrying platform respectively, and the upper ends of the four support legs are rotatably connected to the carrying platform through hinge seats, the support legs on both sides of the carrying platform can extend and retract independently to adjust the height of the support legs, the variable pitch output control terminal of the vehicle controller is connected to the extension and retraction enable terminal of the support legs, by extending and retracting the support legs, the carrying platform can tilt along its width direction and reduce the distance between the two support legs, so that the rescue device can pass through the gap between two lines of vehicles in traffic jams.

[0006] The above technical solution involves a support platform supporting the injured person, a protective device limiting and protecting the injured person, and a rapid rescue device that runs on the ground via wheels at the bottom of its support legs. During traffic jams, the support legs are extended and retracted to tilt the support platform along its width, reducing the distance between the two support legs and thus decreasing the overall width of the rapid rescue device. This allows the device to move through the gaps between the two lines of vehicles in a traffic jam, achieving the goal of quickly rescuing the injured. The rapid rescue device of this invention is small in size, highly mobile, and can move through the gaps between two lines of vehicles in a traffic jam, greatly improving the speed of rescue operations during traffic jams.

[0007] In a preferred embodiment of the present invention, the image detection device is a rotatable image sensor mounted at the front end of the support platform, and the distance detection device is a rotatable distance sensor mounted at the front end of the support platform. The image sensor and the distance sensor can rotate synchronously and face the same direction.

[0008] In the above technical solution, the image sensor and distance sensor can rotate synchronously and face the same direction to obtain obstacles in different directions and their distances, which makes it easier to more accurately know the distance between two parallel vehicles.

[0009] In a preferred embodiment of the present invention, the protective device includes a plurality of straps disposed on a support platform.

[0010] The above-mentioned technical solution uses straps to fix the injured person, which is simple and quick.

[0011] In a preferred embodiment of the present invention, the protective device further includes a baffle provided on the side of the bearing platform. The baffle is located at the lower end when the bearing platform is tilted, and the baffle is an arc-shaped baffle that curves upward and inward from the side of the bearing platform.

[0012] The above technical solution provides support and protection for the lower body of the injured person when the carrying platform tilts along the width direction, preventing the injured person from slipping off the carrying platform and further improving safety.

[0013] In a preferred embodiment of the present invention, the rapid rescue device further includes a counterweight device, which adopts one or a combination of the following structures: Structure 1: The counterweight device includes a counterweight block disposed on the high side when the bearing platform is tilted, or the counterweight block is disposed on a support leg or a travel wheel on the high side when the bearing platform is tilted; Structure 2: The counterweight device includes a support wheel disposed on the inner side of the travel wheel, and the support wheel is telescopically connected to the inner side of the travel wheel through a telescopic rod.

[0014] The above technical solution improves the stability of the rapid rescue device by setting a counterweight, which causes the center of gravity of the rapid rescue device to move towards the higher end of the platform when the platform tilts; and by setting a support wheel, the telescopic rod extends when the platform tilts, causing the support wheel to move towards the inside of the traveling wheel.

[0015] In a preferred embodiment of the present invention, the support wheel is a caster wheel capable of supporting the ground.

[0016] To achieve the second objective mentioned above, the present invention adopts the following technical solution: a control method for a rapid rescue device, comprising the following steps: S1, emergency personnel activate the rapid rescue device and connect it to the network, and set the destination of the rapid rescue device; S2, the image detection device and distance detection device at the front end of the rapid rescue device rotate and detect, obtain the distance between two parallel vehicles in traffic jam, and control the tilt angle of the carrying platform along the width direction and the spacing of the two side support legs according to the distance between the two parallel vehicles; S3, after the rapid rescue device reaches the destination, the injured person is placed on the carrying platform of the rapid rescue device and the protective device is closed; S4, the rapid rescue device carries the injured person back.

[0017] The above technical solution reduces the width of the entire rapid rescue device by tilting the support platform along its width and narrowing the distance between the two supporting legs, so that the rescue device can pass through the gap between two trains stuck in traffic, thus achieving the purpose of quickly rescuing the injured.

[0018] In another preferred embodiment of the present invention, the method for controlling the tilt angle of the bearing platform and the spacing between the two side support legs in step S2 includes: detecting the distance between two rows of vehicles during traffic jams. , The distance between the two trains at position S for the rapid rescue device is calculated based on the distance between the trains. Controlling the tilt angle of the support platform :like If the platform remains horizontal, the distance between the support legs on both sides of the platform remains unchanged. The distance between the support legs on both sides when the platform is horizontal. The safe distance coefficient for rapid rescue devices to pass between two trains; if Then adjust the tilt angle of the support platform. for: At this time, when the platform tilts, the distance between its two supporting legs is adjusted to... .

[0019] The above technical solutions, based on workshop distance Controlling the tilt angle of the support platform ,when When the distance between the two trains is large enough, the platform can pass through while remaining level; when When the gap between the two trains is too small, it indicates that the overall width of the rapid rescue device needs to be reduced so that the rescue device can pass through the gap between the two trains in the traffic jam.

[0020] To achieve the third objective mentioned above, the present invention adopts the following technical solution: a joint rescue control method for a rapid rescue device and an ambulance, comprising the following steps: S11, determining the emergency rescue route and the emergency rescue location; S12, obtaining the vehicle traffic conditions at the emergency rescue location along the emergency rescue route, and determining whether there is traffic congestion at the emergency rescue location and the extent of the congestion; S13, calculating the rescue time based on the traffic congestion conditions, and determining the movement of the rapid rescue device and the ambulance based on the rescue time.

For example, they can refer to mechanical or electrical connections, or internal connections between two components. They can be direct connections or indirect connections through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms according to the specific circumstances.

[0030] Example 1

[0031] This embodiment provides a rapid rescue device, such as Figures 1-3 As shown, in a preferred embodiment, the rapid rescue device includes a support platform 1, four support legs 2 located at the bottom of the support platform 1 for supporting it, a travel wheel 3 located at the bottom of each support leg 2 capable of running on the ground, and a protective device installed on the support platform 1 to limit and protect the injured person. The support platform 1 can be a stretcher or a support plate, and the travel wheels 3 are mounted on the bottom of the support legs 2 via bases 10. The travel wheels 3 are either drive wheels or steering wheels, both existing technologies, and their structure and principles are not detailed here.

[0032] The front end of the carrying platform 1 is equipped with an image detection device 11 for detecting obstacles and a distance detection device 12 for detecting the distance between the front end of the carrying platform 1 and obstacles. The signal output terminals of the image detection device 11 and the distance detection device 12 are connected to the vehicle controller 13, which acquires the distance between two parallel vehicles during traffic jams. The image detection device 11 is a rotatable image sensor mounted on the front end of the carrying platform 1, and the distance detection device 12 is a rotatable distance sensor mounted on the front end of the carrying platform 1. The image sensor and the distance sensor can rotate synchronously and face the same direction to acquire information about obstacles in different directions and their distances.

[0033] Four support legs 2 are symmetrically arranged on the left and right sides of the bearing platform 1 in the width direction. The upper ends of the four support legs 2 are rotatably connected to the bearing platform 1 through hinge seats 9. The support legs 2 on both sides of the bearing platform 1 can extend and retract independently to adjust the height of the support legs 2. The two support legs 2 on the left side of the bearing platform 1 can extend and retract synchronously, and the two support legs 2 on the right side of the bearing platform 1 can also extend and retract synchronously. The variable pitch output control terminal of the vehicle controller 13 is connected to the extension and retraction enable terminal of the support legs 2. By extending and retracting the support legs 2 on both sides of the bearing platform 1, the bearing platform 1 can tilt along its width direction and reduce the distance between the two support legs 2, thereby reducing the width of the entire rapid rescue device so that the rescue device can pass through the gap between two lines of vehicles in traffic jams.

[0034] In this invention, when the support platform 1 tilts along its width, a protective device limits the movement of the injured person, ensuring that the injured person will not slip off the tilted support platform 1. Specifically, the protective device includes several straps 4 provided on the support platform 1, which are used to secure the injured person. More preferably, the protective device also includes a baffle 5 provided on the side of the support platform 1. The baffle 5 is located at the lower end when the support platform 1 is tilted, and the baffle 5 is an arc-shaped baffle 5 that curves upward and inward from the side of the support platform 1. When the support platform 1 is tilted, the outer edge of the baffle 5 will not extend beyond the outer edge of the support platform 1, and will not increase the overall width of the rapid rescue device.

[0035] In another preferred embodiment, the rapid rescue device further includes a counterweight device, which improves the stability of the rapid rescue device when the supporting platform 1 tilts. Specifically, the counterweight device adopts one or a combination of the following structures, preferably both structure one and structure two are provided simultaneously.

[0036] Structure 1: The counterweight device includes a counterweight block 6 located on the high side of the bearing platform 1 when it is tilted, or the counterweight block 6 is located on the support leg 2 or the travel wheel 3 on the high side of the bearing platform 1 when it is tilted. Preferably, the counterweight block 6 is fixed on the base 10 on the high side of the bearing platform 1 when it is tilted and on which the travel wheel 3 is mounted.

[0037] Structure 2: The counterweight device includes a support wheel 7 located inside the traveling wheel 3. The support wheel 7 is a swivel caster capable of supporting the ground. The support wheel 7 is telescopically connected to the inside of the traveling wheel 3 via a telescopic rod 8. The telescopic rod 8 is a horizontally arranged multi-stage electric push rod, and its housing is fixed to the base 10 on which the traveling wheel 3 is mounted. When the support platform 1 tilts, the telescopic rod 8 extends, causing the support wheel 7 to move inward toward the traveling wheel 3, thereby enhancing the stability of the rapid rescue device.

[0038] Example 2

[0039] This embodiment provides a control method for the rapid rescue device based on Embodiment 1, such as... Figures 1-3 As shown, the control method includes the following steps:

[0040] S1. Emergency personnel activate the rapid rescue device and connect it to the network, setting the destination of the rapid rescue device;

[0041] S2. The image detection device 11 and distance detection device 12 at the front end of the rapid rescue device rotate and detect to obtain the distance between two parallel vehicles when stuck in traffic. Based on the distance between the two parallel vehicles, the tilt angle of the bearing platform 1 along the width direction and the spacing between the two side support legs 2 are controlled.

[0042] S3. After the rapid rescue device arrives at the destination, the injured person is placed on the carrying platform 1 of the rapid rescue device and the protective device is closed, specifically by fixing the injured person with straps 4.

[0043] S4. The rapid rescue device carries the wounded back.

[0044] In step S2, the method for controlling the tilt angle of the bearing platform 1 and the spacing between the two supporting legs 2 includes:

[0045] The distance between two lines of vehicles during a traffic jam is detected by the image detection device 11 and the distance detection device 12. , The distance between the two trains at position S for the rapid rescue device is calculated based on the distance between the trains. Control the tilt angle of the support platform 1.

[0046] like Then the supporting platform 1 remains horizontal, and the distance between the supporting legs 2 on both sides of the supporting platform 1 remains unchanged. The distance between the support legs 2 on both sides of the platform 1 when it is horizontal. The safe distance coefficient for the rapid rescue device to pass between two trains can be 1.2 or 1.5 to ensure that the rapid rescue device will not scrape against the vehicles.

[0047] like The tilt angle of the bearing platform 1 can be adjusted by extending the two left support legs 2 or shortening the two right support legs 2. for:

[0048]

[0049] At this moment, the support platform 1 tilts, and the spacing between its two supporting legs 2 automatically adjusts to... Simultaneously, by extending the telescopic rod 8, the support wheel 7 on the inner side of the travel wheel 3 on the lower end of the bearing platform 1 is adjusted to move inward, and the distance of inward movement is: Where h is the height of the hinge seat 9 on the lower side of the bearing platform 1 to the ground.

[0050] In this invention, the specific method for obtaining the distance between two parallel vehicles during traffic jams is as follows:

[0051] S21. Obtain an image of the front of the rapid rescue device through the image detection device 11;

[0052] S22. Select the images of the two vehicles closest to the rapid rescue device from the images obtained in S21;

[0053] S23. Determine the shortest distance d between the boundaries of two parallel vehicles in the filtered image.

[0054]

[0055] in, The distance between the detection device 12 and the right edge of the vehicle on the left in front. The distance detection device 12 moves forward from the front edge of the vertical support platform 1 until it detects the rotation angle of the right edge of the vehicle on the left in front of it. The distance between the detection device 12 and the left edge of the vehicle on the right in front. The distance detection device 12 moves forward from the front edge of the vertical support platform 1 until it detects the rotation angle of the left edge of the vehicle on the right.

[0056] Example 3

[0057] This embodiment provides a joint rescue control method for a rapid rescue device and an ambulance as described in Embodiment 1. The rapid rescue device operates according to the control method of Embodiment 2. This joint rescue control method includes the following steps:

[0058] S11, determine the emergency rescue route and location. Specifically, existing navigation software can be used to generate the route. For example, this can be achieved by linking the emergency command center's GIS geographic information system with emergency call terminals (such as user mobile apps): After receiving a rescue request, the emergency command center first obtains the user's real-time location as the initial emergency rescue location through the user's terminal. Then, it combines this with the city's traffic big data platform (such as the traffic police department's real-time traffic system) to plan three alternative emergency rescue routes, and uses an algorithm to select the optimal route with the fewest traffic lights and the lowest historical congestion rate.

[0059] S12: Obtain vehicle traffic information at the emergency rescue location along the emergency rescue route to determine if there is traffic congestion and the extent of the congestion. Specifically, this can be achieved through real-time interaction between the Beidou positioning terminal on the ambulance and traffic cameras along the route, obtaining data such as vehicle speed and queue length at the emergency rescue location (e.g., within 500 meters of an intersection). If the detected vehicle speed is below 10 km / h and the queue length exceeds 300 meters, it is classified as "severe traffic congestion"; if the speed is between 10 and 30 km / h and the queue length is between 100 and 300 meters, it is classified as "mild traffic congestion".

[0060] S13: Calculate the rescue time based on traffic congestion, and determine the deployment of rapid rescue devices and ambulances based on the rescue time.

[0061] Specifically, in this embodiment, the method for calculating the rescue time based on traffic congestion is as follows:

[0062] Determine the distance L1 between the initial location of the traffic jam and the location of emergency rescue, and the distance L2 between the first open intersection and the next open exit at the location of the traffic jam.

[0063] If the time taken for the rapid rescue device to travel from L1 is greater than the time taken for the ambulance to travel from L1, then the rescue time T1 = the travel time of the ambulance + the rescue time.

[0064] If the time taken for the rapid rescue device to travel from L1 is less than the time taken for the ambulance to travel from L1, and the time taken for the rapid rescue device to travel from L2 is greater than the time taken for the ambulance to travel from L2, then the rescue time T2 = the time taken for the ambulance to travel to the traffic jam location + the time taken for the rapid rescue device to travel from the traffic jam location to the emergency location + the emergency time + the travel time taken for the ambulance to travel from the emergency location to the emergency center.

[0065] If the travel time of the rapid rescue device from L1 is less than the travel time of the ambulance from L1, and the travel time of the rapid rescue device from L2 is less than the travel time of the ambulance from L2, then the rescue time T3 = the time it takes for the ambulance to travel to the intersection before the traffic jam + the travel time of the ambulance from the next open exit after the traffic jam to the emergency center + the travel time of the rapid rescue device from the previous open intersection after the traffic jam to the next open exit after the traffic jam + the emergency rescue time. Preferably, two ambulances can be arranged, one to deliver and one to pick up, or one can detour to the next intersection.

[0066] Determine the minimum value of T1, T2, and T3. If T1 is the minimum, the ambulance will drive directly to the rescue location. If T2 is the minimum, the ambulance will drive to the traffic jam location and drop off the rapid rescue device. The rapid rescue device will then travel from the traffic jam location to the emergency location to provide emergency care. The ambulance will then follow its original route to the emergency location to reconnect with the rapid rescue device. If T3 is the minimum, the ambulance will drive to the intersection above the traffic jam location and drop off the rapid rescue device. The rapid rescue device will then travel to the emergency location to provide emergency care and then travel to the next open exit from the traffic jam location. The ambulance will then detour to the next open exit from the traffic jam location, or another ambulance will be dispatched to the next open exit from the traffic jam location. The ambulance will then reconnect with the rapid rescue device from the next open exit from the traffic jam location.

[0067] This embodiment achieves the following technical effects through a closed-loop control logic of "route and location determination—traffic condition assessment—rescue time calculation—dual rescue vehicle driving decision":

[0068] 1) Dynamic Route Optimization and Intelligent Decision-Making. By integrating geographic information systems, real-time traffic big data (such as the number of traffic lights and historical congestion rates) and multi-source sensing data (vehicle speed and queue length), the system can dynamically plan the optimal rescue route and automatically select the most time-saving rescue mode based on real-time traffic conditions. This data-driven intelligent decision-making mechanism effectively avoids delays caused by traffic congestion and significantly shortens emergency response time.

[0069] 2) Multi-mode collaborative rescue with strong adaptability. Three rescue time calculation models (T1, T2, T3) were designed, which can flexibly select different strategies such as "full-process ambulance", "vehicle + device relay", or "two-vehicle cross-congestion point shuttle" according to the severity of traffic congestion and road structure. Especially in severe congestion scenarios, the use of rapid rescue devices to cross congestion points, ambulance detours, or two-vehicle relays effectively overcomes physical traffic limitations and ensures the timeliness of rescue.

[0070] 3) Refined traffic congestion assessment and segmented control. By setting multi-dimensional thresholds such as vehicle speed and queue length, the system can accurately identify "mild traffic congestion" and "severe traffic congestion". Furthermore, it combines the distance between congestion intervals (L1, L2) for segmented spatiotemporal analysis, making the dispatch of rescue resources more precise. It can match the optimal traffic mode in different road segments and avoid resource waste and time loss.

[0071] 4) Minimize the entire rescue process time. By comparing the traffic efficiency of ambulances and rapid rescue devices on different road sections, and with the goal of "minimizing the total rescue time", the time consumed in the driving, connecting, and emergency rescue stages is calculated. This optimizes task allocation and route execution at the global level, ensuring maximum efficiency throughout the entire process from receiving the alarm to arriving at the emergency center.

If the time taken by the rapid rescue device to travel from L1 is less than the time taken by the ambulance to travel from L1, and the time taken by the rapid rescue device to travel from L2 is greater than the time taken by the ambulance to travel from L2, then the rescue time T2 = the time taken by the ambulance to travel to the traffic jam location + the time taken by the rapid rescue device from the traffic jam location to the emergency location + the emergency time + the travel time taken by the ambulance from the emergency location to the emergency center. If the time taken for the rapid rescue device to travel from L1 to L2 is less than the time taken for the ambulance to travel from L1, and the time taken for the rapid rescue device to travel from L2 to L2 is less than the time taken for the ambulance to travel from L2 to L2, then the rescue time T3 = the time taken for the ambulance to travel to the intersection before the traffic jam + the time taken for the ambulance to travel from the next open exit after the traffic jam to the emergency center + the time taken for the rapid rescue device to travel from the previous open intersection after the traffic jam to the next open exit after the traffic jam + the emergency rescue time. Determine the minimum value of T1, T2, and T3; If T1 is the smallest, the ambulance will drive directly to the rescue location to provide assistance. If T2 is the smallest, the ambulance will drive to the traffic jam location and drop the rapid rescue device. The rapid rescue device will then drive from the traffic jam location to the emergency location to provide first aid. The ambulance will then drive along the original route to the emergency location and reconnect the rapid rescue device. If T3 is the smallest, the ambulance will drive to the intersection above the traffic jam location and drop off the rapid rescue device. The rapid rescue device will then drive to the emergency location to provide first aid and drive to the next open exit from the traffic jam location. The ambulance will then detour to the next open exit from the traffic jam location, or another ambulance will be dispatched to the next open exit from the traffic jam location. The ambulance will then connect with the rapid rescue device at the next open exit from the traffic jam location.
