Description

Technical Field

[0001] The present application relates to the field of wireless control technology, and in particular to a multifunctional rescue vehicle control system based on wireless control. Background Art

[0002] Natural disasters often occur, such as floods, mudslides, earthquakes, etc. With the development of science and technology, in order to improve rescue efficiency, the rescue team's equipment is also gradually being updated.

[0003] For example, in the event of a flood disaster, the priority of rescue must be the victims, followed by important supplies. Currently, it is impossible to have both. The victims can be rescued by helicopter or hovercraft. Since helicopters and hovercraft require rescue personnel to drive, when the rescue force is limited, the rescue of supplies will inevitably be abandoned. Therefore, property losses will be caused after the disaster. In addition to rescuing supplies, the same situation will be encountered when transporting relief supplies to flood-stricken areas.

[0004] Although domestic automatic control is developing rapidly, there is currently no automatic control system specifically for rescue equipment. The reason is that the rescue environment is harsh. For example, during flood disasters, the underwater and surface conditions are unclear, and the water depth is different. When the water depth is too shallow, it is impossible to use ship transportation for rescue. If the water is too deep, it is impossible to use rescue carts for transportation and rescue.

[0005] In view of this, it is necessary to transform and upgrade the current rescue equipment so that it can be automatically controlled to reduce the labor intensity of rescue workers and be suitable for disaster rescue in harsh environments. Summary of the invention

[0006] The main purpose of the present application is to provide a multifunctional rescue vehicle control system based on wireless control, which reduces the labor intensity of rescue personnel and has strong adaptability to the harsh disaster area environment.

The surface image data taken by the second camera is sent to the drone controller, and the drone controller sends the surface image data to the control gimbal through the first wireless communication module. The control instruction of the control gimbal is sent to the drone controller through the first wireless communication module, and then sent to the rescue vehicle controller by the drone controller through the second wireless communication module. The rescue vehicle controller controls the tail rudder and the power assembly based on the control instruction.

[0008] A further improvement is that a height adjustment mechanism is provided between the buoyancy support assembly and the base frame, a first sensor for detecting water depth is provided at the bottom of the buoyancy support assembly, the rescue vehicle controller is electrically connected to the height adjustment mechanism and the first sensor respectively, the rescue vehicle controller receives the water depth value detected by the first sensor and compares it with a preset value, and controls the height adjustment mechanism to adjust the height of the buoyancy support assembly relative to the base frame based on the comparison result.

[0009] A further improvement is that the buoyancy support assembly includes a mounting frame, a plurality of hollow pontoons fixedly disposed on both sides of the bottom of the mounting frame, and an air bag assembly disposed between the hollow pontoons on both sides; an air compressor is disposed on the upper portion of the base frame; the air compressor is connected to the hollow pontoons and the air bag assembly through an air supply pipe; the hollow pontoons include staggered sealed pontoons and open pontoons with openings facing downward.

[0010] As a further improvement, a weighing unit for detecting the weight of the load is provided on the base frame or the load frame, and the rescue vehicle controller controls the buoyancy of the buoyancy support assembly in water based on the detection data of the weighing unit.

[0011] A further improvement is that the height adjustment mechanism includes a motor arranged on the base frame, a lifting screw sleeve arranged on the base frame only for rotation, a lifting screw sleeve fixedly arranged on the mounting frame and cooperating with the lifting screw sleeve, and a transmission structure is arranged between the lifting screw sleeve and the motor shaft of the motor.

[0024] In addition, the term "plurality" shall mean two or more.

[0025] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0026] like Figure 1-Figure 5 As shown, a multifunctional rescue vehicle control system based on wireless control includes a control platform 12, a pilot drone component and a rescue vehicle body; The rescue vehicle body includes a chassis 1, a cargo frame 4 fixedly arranged on the upper part of the chassis 1, a buoyancy support component arranged at the bottom of the chassis 1, a tail rudder and a power component arranged at the tail of the chassis 1, a first camera arranged at the bottom of the chassis 1, a rescue vehicle controller arranged on the chassis 1, and wheels 2 rotatably arranged on both sides of the chassis 1. The rescue vehicle controller is electrically connected to the buoyancy support component, the tail rudder, the power component and the first camera respectively, wherein the power component preferably adopts a propeller. It should be noted that the tail rudder, the power component and the first camera 2. The buoyancy support component is only used when the rescue vehicle body is in the ship state, that is, when encountering a deep wading area on the path of rescue or transportation of rescue materials, the rescue vehicle body is changed to the ship state, and in the shallow wading area, the push cart state is adopted. Since the control ability of personnel in the water is poor when wading in the disaster area, such as the current hovercraft, not only does it require personnel to control in the water, but also the personal safety of rescue personnel cannot be guaranteed when encountering large waves. However, the rescue vehicle can change the state at any time according to the actual situation, and the materials are placed in the cargo frame 4, and there is no need to load and unload when switching the state, which reduces the labor intensity of rescue personnel; The pilot drone assembly includes a drone body 11, a second camera arranged on the drone body 11, and a drone controller arranged on the drone body 11, wherein the drone controller is electrically connected to the second camera; a first wireless communication module is arranged between the control platform 12 and the drone controller, and a second wireless communication module is arranged between the drone controller and the rescue vehicle controller; the underwater image data taken by the first camera is sent to the rescue vehicle controller, and the rescue vehicle controller sends the underwater image data to the drone controller through the first wireless communication module, and the drone controller sends the underwater image data to the control platform 12 through the second wireless communication module; the surface image data taken by the second camera is sent to the drone controller, and the drone controller sends the surface image data to the control platform 12 through the first wireless communication module; the control instruction of the control platform 12 is sent to the drone controller through the first wireless communication module, and then sent to the rescue vehicle controller by the drone controller through the second wireless communication module; the rescue vehicle controller controls the tail rudder and the power assembly based on the control instruction.

[0027] It is further explained that the above-mentioned first camera adopts an underwater camera, and the specific structure is not repeated here. The image collected underwater is transmitted to the control gimbal 12 in real time through the first wireless communication module and the second wireless communication module. The operator of the gimbal can obtain the underwater conditions in time, and thus issue corresponding control instructions according to the underwater conditions. As for the state of the water surface, it is obtained through the second camera on the pilot drone. Similarly, the operator can make corresponding countermeasures in advance according to the water surface conditions to ensure that the rescue vehicle body adjusts the direction through the tail rudder and adjusts the speed through the power component so that it can smoothly pass through the flooded area in the ship state, which is suitable for the transportation of materials in flooded areas with harsh environments.

[0028] Moreover, the gimbal operators do not need to conduct on-site rescue operations, which reduces the number of on-site rescue personnel. When the rescue vehicle itself is in the ship state, the on-site rescue personnel can be transported by helicopter or lifeboat, which also reduces the labor intensity of the on-site rescue personnel.

[0029] A height adjustment mechanism is provided between the buoyancy support assembly and the base frame 1, and a first sensor for detecting water depth is provided at the bottom of the buoyancy support assembly. The rescue vehicle controller is electrically connected to the height adjustment mechanism and the first sensor respectively. The rescue vehicle controller receives the water depth value detected by the first sensor and compares it with a preset value, and controls the height adjustment mechanism to adjust the height of the buoyancy support assembly relative to the base frame 1 based on the comparison result. The first sensor adopts an ultrasonic ranging sensor.

[0030] It should be noted that for areas with shallow water, rescue personnel are still responsible for pushing the vehicle. The comparison benchmark can be set to the distance between the buoyancy support component and the lowest point of the wheel 2 when the buoyancy support component is in the lowest state. When the water depth is less than this distance, the vehicle is pushed in the cart state. The preset value can be set to the distance between the buoyancy support component and the lowest point of the wheel 2 in the current state. If the distance between the buoyancy support component and the lowest point of the wheel 2 in the current state is greater than the water depth, the height adjustment mechanism adjusts the buoyancy support component downward to ensure that the water depth is greater than the above distance. This ensures that the wheels 2 of the loaded rescue vehicle are off the ground in the ship state, and can avoid collision in time when encountering potholes on the ground, so as to cope with disaster rescue in complex and harsh environments. In addition, the specific structure of the height adjustment mechanism The structure can be: the height adjustment mechanism includes a motor 15 arranged on the base frame 1, a lifting screw sleeve 14 which is only rotatably arranged on the base frame 1, and a lifting screw 13 which is fixedly arranged on the mounting frame 6 and cooperates with the lifting screw sleeve 14. A transmission structure is arranged between the lifting screw sleeve 14 and the motor 15 shaft of the motor 15, and the transmission structure can adopt gear transmission. For example, a driving gear is fixedly arranged on the motor 15 shaft of the motor 15, and a transmission gear meshing with the driving gear is concentrically fixedly arranged on the lifting screw sleeve 14. The driving gear is driven to rotate by the motor 15, and the driving gear drives the transmission gear to rotate, thereby driving the lifting screw sleeve 14 to rotate, thereby driving the lifting screw sleeve 14 to rotate, thereby driving the lifting screw sleeve 13 to move upward or downward, and then realizing the height adjustment of the mounting frame 6.

[0031] The buoyancy support assembly includes a mounting frame 6, a plurality of hollow pontoons fixedly disposed on both sides of the bottom of the mounting frame 6, and an air bag assembly 9 disposed between the hollow pontoons on both sides. An air compressor is disposed on the upper portion of the base frame 1, and the air compressor is connected to the hollow pontoons and the air bag assembly 9 through an air supply pipe. The hollow pontoons include staggered sealed pontoons 7 and open pontoons 8 with openings facing downward.

[0032] It should be noted that, in the pushing state, the airbag assembly 9 is in a deflated state, and there is no compressed air in the open pontoon 8 and the sealed pontoon 7. It only serves to strengthen the support of the chassis 1. When it is needed to be in a ship state, the air compressor generates compressed air to inflate the airbag assembly 9, the sealed pontoon 7 and the open pontoon 8. The airbag is deployed to generate buoyancy. The buoyancy generated by the airbag can be the same as the gravity of the rescue vehicle body when it is empty, and the weight of the load is adjusted by the sealed pontoon 7 and the open pontoon 8. According to the load situation, some of the sealed pontoons 7 can be selected to be inflated. As for the setting of the open pontoon 8, since water in the water can seal the gas, it can be deflated in time to prevent the instantaneous buoyancy of the load change from being too large when leaving the water surface, so as to play a role in maintaining stability. In addition, in order to be able to adjust the float in real time according to the load weight The force is adjusted, a weighing unit for detecting the weight of the load is provided on the base frame 1 or the load frame 4, and the rescue vehicle controller controls the buoyancy of the buoyancy of the buoyancy support assembly in the water based on the detection data of the weighing unit. The above record states that the buoyancy generated by the airbag is equal to the gravity of the rescue vehicle body in an unloaded state, that is, the buoyancy generated by the airbag after deployment is sufficient to support the rescue vehicle body, and the gravity of the load is supported by the buoyancy generated by the sealed buoyancy box 7 and the open buoyancy box 8. Since there are multiple sealed buoyancy boxes 7 and open buoyancy boxes 8, the number of buoyancy boxes that need to be inflated is adjusted according to the weight of the load. It should be noted that sealed chambers are fixedly provided at the front and rear ends of the load frame 4, and components such as air compressors and motors are arranged in the sealed chambers. In addition, the setting of the sealed chambers improves the overall strength of the load frame 4, so that the load frame 4 is not easily deformed when carrying objects.

[0033] In addition, there will be certain tributaries in the waters generated in the flood-stricken areas. During the transportation process in the ship state, one side of the rescue vehicle body will be affected by the impact of the water flow when encountering the tributaries, and it is easy to deviate. In order to solve the above problems, in this embodiment, preferably, the outer sides of the sealed buoys 7 on both sides are provided with air nozzles 10, and the air nozzles 10 are connected to the sealed buoys 7 through valves. The second sensor and the third sensor for detecting water pressure are respectively provided on both sides of the chassis 1 or the buoyancy support assembly. The rescue vehicle controller controls the gradual opening of the valve of the air nozzle 10 on the corresponding side based on the difference between the detection values ​​of the second sensor and the third sensor until the detection values ​​of the second sensor and the third sensor tend to be equal. For example, when the second sensor detects that the water pressure on the left side of the rescue vehicle body is greater than the water pressure on the right side of the rescue vehicle body detected by the third sensor, the rescue vehicle body will deviate to the right when moving forward. Therefore, the rescue vehicle controller controls the air nozzle 10 on the right side of the sealed buoy 7 to start spraying compressed air to generate reverse thrust, pushing the heading of the rescue vehicle body to adjust to the left, thereby maintaining the straightness during the forward process. The second sensor and the third sensor are water pressure sensors.

[0034] In this embodiment, preferably, a beacon device is also provided on the chassis 1, and a wireless signal recognition device for wireless communication with the beacon device is provided on the drone body 11. The drone controller determines the distance between the drone and the beacon device based on the wireless signal recognition device to adjust the flight speed of the drone in real time. The beacon device is an existing conventional product, and its specific structure and principle are not repeated here. The beacon device is a small wireless signal transmitter based on low-power Bluetooth (BLE) technology, and the wireless signal recognition device on the drone body 11 is actually a signal receiver. The cooperation of the two can realize the measurement of the distance between the drone and the rescue vehicle, so that the drone controller can compare the measured distance with the preset value, thereby automatically adjusting the flight speed of the drone in real time, and the path of the drone and the rescue vehicle is controlled by the gimbal operator or according to the preset path.

[0035] Preferably in this embodiment, the rescue vehicle body also includes a support frame 3 fixedly arranged at the bottom of the base frame 1 and a push rod 5 fixedly arranged on the cargo frame 4. By setting the support frame 3, it and the wheels 2 together form a support for the ground, so that the rescue vehicle can maintain its body stability when loading and unloading supplies. Secondly, by setting the push rod 5, the rescue vehicle body is convenient for operators to push in the push car state, and both ends of the push rod 5 extend out of the rescue vehicle body. Therefore, in some relatively steep or inconvenient areas, multiple people in the front and back can lift the rescue vehicle body together with the supplies to facilitate passing through the area, thereby improving the contingency measures for different environmental areas.

[0036] like Figure 4 As shown, preferably, the mounting frame 6 is provided with a strap assembly for fixing the deflated airbag. When the rescue vehicle body is in a state of being pushed by a cart, the airbag is in a compressed state. At this time, it is fixed to the bottom of the mounting frame 6 and located in the gap between the buoys on both sides by a binding assembly, thereby ensuring that the airbag will not interfere when the cart is pushed. When it is necessary to change to the ship state, the strap assembly can be removed and the airbag can be inflated.

[0037] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
