Description

Technical Field

[0001] The present invention belongs to the technical field of oil transportation, and relates to a multi-domain distribution type intelligent refueling system and method. Background Art

[0002] Natural disasters, such as earthquakes, floods, and mudslides, often bring serious disasters to human society with their huge destructive power and unpredictability. These disasters not only directly threaten people's lives and safety, but also cause serious damage to key infrastructure such as roads, bridges, power supply, and oil supply, making the disaster area fall into an extremely difficult situation in a short period of time. In such an emergency, quickly restoring power supply, ensuring the mobility of vehicles, and the normal operation of rescue machinery are crucial for carrying out emergency rescue operations and post-disaster reconstruction.

[0003] Fuel, as an indispensable energy source for the operation of these key equipment, is particularly prominent and important after a disaster. After a natural disaster, due to road damage, power outages and other reasons, traditional fuel supply methods often fail to meet the needs of the disaster area in a timely and effective manner. On the one hand, road interruptions make it difficult for fuel transport vehicles to pass, resulting in the inability to deliver fuel to the disaster area in a timely manner; on the other hand, the damage to the power supply system also makes it impossible for fuel supply facilities such as gas stations to operate normally, further exacerbating the tension in fuel supply.

[0004] At present, the following three methods are used to transport fuel to the disaster area: (1) Use helicopters to airdrop fuel supplies such as oil bags and barrels. However, the accuracy of this method is difficult to guarantee. Since the disaster-stricken areas are often complex in terrain, a slight deviation in the landing point may cause the oil bags or barrels to fall in difficult-to-access places, causing great inconvenience for subsequent retrieval and use. In addition, there may be safety risks during the airdrop process, such as the oil bags or barrels rupturing when landing, causing fires or environmental pollution.

[0005] (2) Use skid-mounted gas stations to open temporary refueling points. Skid-mounted gas stations are easy to install and highly mobile, and can provide fuel supplies to disaster areas in a short period of time. However, this solution also has limitations. On the one hand, the opening of skid-mounted gas stations requires a relatively wide area, which is often difficult to find in disaster areas. On the other hand, skid-mounted gas stations cannot cross damaged sections of road, and are not suitable for locations where fuel is urgently needed but traffic is blocked.

[0006] (3) Use mobile refueling trucks to deliver fuel to the door. Mobile refueling trucks have the advantages of high flexibility and wide coverage, and can deliver fuel according to the actual needs of the disaster area. However, this method also has difficulties that are difficult to overcome. Due to the serious damage to the roads in the disaster area, mobile refueling trucks are often unable to cross the damaged sections of the road. Sometimes even if they can reach nearby, it is difficult to deliver the fuel to the urgently needed places. In addition, mobile refueling trucks need to be driven by people, and in disaster areas, human resources are often very tight. Summary of the invention

[0007] The purpose of the present invention is to solve the technical problems in the prior art and provide a multi-domain distribution type intelligent refueling system and method to realize fuel distribution in multiple areas under disaster environments.

The robotic arm is controlled to aim the refueling gun at the pipeline system and start the oil pump.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0028] The present invention is further described in detail below in conjunction with the accompanying drawings: The first purpose of the present invention is to provide a multi-domain distribution-type intelligent refueling system. The multi-domain distribution-type intelligent refueling system is mounted on a mobile chassis. Through the movement of the mobile chassis, it can accurately reach the vicinity of vehicles, devices, etc. that need fuel, thereby performing unmanned refueling in multiple areas. The unmanned oil transport device 5 can realize air transportation and accurately land at the location where fuel is needed, solving the problem of multi-domain fuel distribution in disaster environments.

[0029] Specifically, Figure 1 and Figure 2 As shown, the multi-domain distribution type intelligent refueling system includes a pallet 1, an oil tank 2, a pipeline system 3, an unmanned refueling action execution device 4, an unmanned oil transportation device 5 and a placement platform 6; the oil tank 2 and the pipeline system 3 are arranged on the top of the pallet 1; the pipeline system 3 is connected to the oil tank 2 through the unmanned refueling action execution device 4; a placement platform 6 is arranged above the pallet 1; the pallet 1 and the placement platform 6 are connected by a number of columns; the unmanned oil transportation device 5 is placed on the placement platform 6; the pipeline system 3 and the unmanned oil transportation device 5 are connected.

[0030] As the basic support structure of the entire refueling system, the pallet 1 can ensure the stability of the oil tank 2, the pipeline system 3 and other equipment. At the same time, the design of the pallet 1 can easily move the entire refueling system to reach the vicinity of the equipment or area where refueling is required. The oil tank 2 is used to store fuel and provide sufficient fuel reserves for the unmanned oil transport device 5. The pipeline system 3 is responsible for transporting fuel from the oil tank 2 to the unmanned oil transport device 5. At the same time, the pipeline system 3 also has anti-leakage and explosion-proof functions to ensure the safety and stability of the refueling process. The unmanned refueling action execution device 4 is used to connect the pipeline system 3 and the oil tank 2. The unmanned oil transport device 4 is used to automatically transport fuel between multiple refueling points, realizing the intelligent distribution of fuel. By integrating navigation, positioning and obstacle avoidance technology, the unmanned oil transport device 4 can independently complete the transportation task, improving the flexibility and efficiency of fuel distribution. At the same time, it reduces manual intervention and transportation costs, and improves the intelligence level of the entire refueling system. The placement platform 6 is used to support and fix the unmanned oil transport device 4, and also has the function of adjusting the height and angle to achieve the level of the placement platform 6 to meet the needs of different terrains and environments.

[0031] like Figure 3As shown, the unmanned oil transport device 5 includes an unmanned aerial vehicle system 51, a fuel tank 52 and a communication system 53 arranged on the unmanned aerial vehicle system 51. The unmanned aerial vehicle system 51 has the ability to take off and land vertically and hover in the air, and can flexibly distribute fuel in complex terrain and narrow spaces, thereby improving the efficiency and flexibility of distribution. The operator can control and monitor the unmanned aerial vehicle from a safe distance, thereby reducing the safety risk of the operator. The unmanned aerial vehicle system 51 can autonomously plan the flight route as needed to achieve accurate fuel distribution. The fuel stored in the fuel tank 52 is used for the needs of multiple refueling points; the communication system 53 provides a real-time communication link between the unmanned aerial vehicle system 51 and the ground control center, ensuring the accurate communication of instructions and the real-time transmission of data. Using the communication system 53; at the same time, the ground control center can monitor the flight status and fuel distribution of the unmanned aerial vehicle in real time, and promptly discover and deal with potential problems.

[0032] The drone system 51 is also equipped with a camera, which uses advanced computer vision technology and deep learning algorithms to accurately identify and quickly locate the target. This is crucial for the drone to accurately find the refueling point or target location when delivering fuel in complex terrain and narrow spaces. Through the recognition ability of the camera, the drone can perform delivery tasks more accurately and improve the accuracy and efficiency of delivery.

[0033] The pipeline system 3 includes a first pipeline and a second pipeline; the first pipeline is connected to the unmanned oil transport device 5, the second pipeline is connected to the oil tank 2, and the pipeline system 3 is connected to the operation control system 7; the operation control system 7 includes a pressure sensor, a flow meter and a control valve connected to the pipeline. The pressure sensor is used to monitor the fuel pressure in the pipeline in real time to ensure the stability of the fuel pressure during the transportation process and avoid damage to the pipeline and refueling equipment due to excessive or low pressure. The flow meter can accurately measure the flow of fuel, which helps to promptly discover and deal with abnormal flow problems. By opening and closing the control valve, the flow rate of the fuel can be accurately adjusted to achieve precise control of the refueling process. In addition, in an emergency, the control valve can also quickly cut off the flow of fuel to ensure the safety of the system.

[0034] The first pipeline port is provided with a refueling connector; the refueling connector is provided on the mounting platform 6; the refueling connector is connected to the fuel tank 52 of the unmanned oil transport device 5. The refueling connector is provided on the mounting platform 6, so that the area and space of the mounting platform 6 can be fully utilized, so that the unmanned oil transport device 4 can directly approach and connect to the refueling connector when landing or docking, without additional movement or adjustment, thereby improving the convenience and efficiency of refueling. At the same time, multiple refueling connectors are provided on the mounting platform 6, so that the fuel tanks 52 of multiple unmanned oil transport devices 5 can be refueled.

[0035] Exemplarily, the refueling joint is a dry-type sealing joint. The dry-type sealing joint can achieve a good sealing effect without the aid of lubricants or media, avoiding the risk of fuel leakage; at the same time, it reduces the maintenance and servicing work required for traditional wet joints, reducing maintenance costs and time.

[0036] The unmanned refueling action execution device 4 includes a mechanical arm and an intelligent recognition component; the intelligent recognition component is electrically connected to the mechanical arm; the intelligent recognition component can capture and recognize the position, shape, size and other information of the refueling gun and the second pipe in real time through devices such as cameras and sensors, providing a reliable basis for the precise control of the mechanical arm; secondly, it also has an intelligent judgment function, which can automatically adjust the action parameters of the mechanical arm according to the recognition results, such as the moving speed and rotation angle, so as to ensure the smooth progress of the refueling process.

[0037] The pipeline system 3 is connected to the oil tank 2 through a mechanical arm; a refueling gun is provided on the mechanical arm; a refueling gun is provided on the mechanical arm; the refueling gun and the oil tank 2 are connected through a third pipeline; a filtering device and an oil pump are provided on the third pipeline. The mechanical arm has high-precision and high-flexibility control capabilities. It can accurately locate and firmly connect the refueling gun and the pipeline system 3 to ensure that the fuel can be accurately injected. Through a preset program or instruction, the mechanical arm can automatically complete a series of actions in the refueling process, such as moving the refueling gun fixedly connected to it to align it with the second pipeline, which greatly improves the automation and efficiency of refueling. The oil pump is responsible for pumping the fuel in the oil tank 2 to the refueling gun through the third pipeline, and then inputting it into the pipeline system 3, and then transporting it to the refueling interface to realize the replenishment of the fuel of the unmanned oil transport device 5. The filtering device can remove impurities contained in the medium in the pipeline, such as dust, moisture, oil, suspended matter, solid particles and microorganisms, and prevent the oil from being contaminated, ensuring the cleanliness and quality of the oil.

[0038] The oil pump is provided with an oil pump tachometer, which can timely detect abnormal conditions of the oil pump, such as too high or too low speed, etc. By timely detecting and handling abnormal conditions, the occurrence or expansion of faults can be avoided, thereby ensuring the stable operation of the oil pump.

[0039] The oil tank 2 is provided with an oil tank level gauge. Through the data of the oil tank level gauge, the operator can more accurately grasp the inventory of fuel, thereby optimizing the dispatch and distribution plan of fuel. When the inventory of oil tank 2 is lower than a certain threshold, the system can automatically trigger an alarm to remind the operator to take timely measures to replenish the fuel in oil tank 2.

[0040] A second object of the present invention is to provide a multi-domain distribution type intelligent refueling method, which specifically comprises the following steps: The multi-domain distribution intelligent refueling system is mounted on a mobile chassis, and the mobile chassis moves to accurately reach the vicinity of vehicles, devices, etc. that need fuel. The mechanical arm is controlled to aim the refueling gun at the pipeline system 3, and the oil pump is started. The fuel flows from the oil tank 2 through the refueling gun, enters the pipeline system 3, and then reaches the refueling interface of the installation platform 6, and reaches the fuel tank 52 through the refueling interface; when the fuel tank 52 is full of oil, the oil pump is turned off, and the control valve is closed by the operation control system 7 to cut off the fuel transportation; the unmanned aerial vehicle system 51 arrives at the designated location according to the guidance of the communication system 53, and delivers fuel to the required fuel equipment. After completion, it returns to the installation platform 6, opens the control valve and starts the oil pump to continue to replenish the fuel in the fuel tank 52, and the above steps are repeated to complete the distribution of fuel to multiple areas.

[0041] Among them, the fuel flows from the oil tank 2 through the third pipeline to the refueling gun, the filter device in the third pipeline filters the fuel, and the oil pump provides power; after the oil tank 52 is filled with oil, the oil pump automatically closes (the control valve also automatically closes after the oil pump is closed), and when the oil tank 52 that is not filled with oil is connected to the refueling interface, the oil pump automatically opens until the oil tank 52 is filled with oil and then closes. The automatic delivery and cut-off of the fuel are precisely controlled by the operation control system, ensuring that the fuel can be stopped in time after the oil tank is filled, avoiding excessive delivery and waste of fuel.

[0042] The multi-domain distribution type intelligent refueling system of the present invention uses unmanned operation, and plans and navigates the route of the drone 51 through the communication system 53 to achieve accurate fuel distribution in multiple regions; the fuel in the oil tank 2 is delivered to the refueling interface through the automatic opening and closing of the mechanical arm and the oil pump, and the fuel in the drone tank 52 is replenished. Unmanned operation makes the system free from the restrictions of time, location and human resources, and can achieve simultaneous or continuous distribution to multiple regions, greatly expanding the coverage of fuel distribution, and unmanned operation reduces labor costs, and reduces the management difficulty and cost expenditure in the fuel distribution process.

[0043] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
