Description

Technical Field

[0001] The present invention relates to the field of communication technology, and in particular to a data return transmission system and a data return transmission method based on an unmanned vehicle. Technical Background

[0002] With the prevalence of smart devices, the amount of data stored on terminals continues to grow, and the demand for timely data sharing is becoming increasingly greater, so we are faced with the problem of how to quickly upload data. Currently, the data stored on terminals is relatively large and is basically transmitted via wired networks. For example, deploying surveillance video in a specific area basically requires the construction of network lines to meet data transmission needs, which brings the limitation that the lines need to be set up in advance. Similarly, the recording and storage functions of personal terminal devices are becoming increasingly powerful. If users need to share big data during the data generation process, they can only upload data in places with network access, such as home, office, or hotel.

[0003] In these scenarios, while network coverage is nearly complete, high-speed bandwidth is still lacking. Furthermore, we often don't want to spend too much time and effort processing data, and we certainly don't want to make a special trip just to get a large amount of data within a certain timeframe. In many scenarios, we have large volumes of data, such as large amounts of photos or videos captured during travel, or data from temporary surveillance systems running for multiple days. In these cases, establishing dedicated data channels for this data is uneconomical, and there's no way to quickly transmit it back over limited network bandwidth. Data cannot be immediately cleared or stored, so an efficient system and method are needed to meet the needs of timely data transmission. Summary of the Invention

[0043] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with specific embodiments of the present invention and corresponding drawings. In the description of the present invention, it should be noted that the term "or" is generally used in the sense of including "and / or" unless the content clearly indicates otherwise.

[0044] It should be noted that the "driverless driving" in this article should be understood in a broad sense, including driving situations where there is no driver at all, as well as situations where the driving is mainly automatic but the driver occasionally takes control.

[0045] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with specific embodiments of the present invention and corresponding drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0046] To address the problems existing in the prior art, the present invention provides a data backhaul system and method based on unmanned vehicles. The system includes an unmanned vehicle dispatching platform, an unmanned vehicle, and a data upload point. The unmanned vehicle dispatching platform receives data backhaul requests from terminal devices, generates dispatch tasks based on the data backhaul requests, and sends the task instructions to the unmanned vehicle. The unmanned vehicle then automatically travels to the location of the terminal device, transfers data via a high-bandwidth wireless local area network, and receives data packets from the terminal device. The unmanned vehicle then automatically travels to the data upload point, transfers data packets via a high-bandwidth wireless local area network, and transmits the data packets to the data upload point, which then uploads the data packets. This system allows users to quickly transfer data in specific scenarios and upload user data to the cloud without user interaction. This system enables low-cost, flexible, and automated asynchronous data upload within a specified timeframe in a streamlined manner. This truly automates the entire data transfer and upload process, similar to a mobile hard drive. The technical solution is further described in the Examples.

[0047] Example 1:

[0048] like Figure 1 As shown, a schematic diagram of the architecture of a data backhaul system based on an unmanned vehicle is provided, which includes an unmanned vehicle dispatching platform 10, an unmanned vehicle 20 and a data upload point 30.

[0049] The main responsibilities of the unmanned vehicle dispatching platform 10 are vehicle dispatching, task dispatching, etc. The unmanned vehicle dispatching platform 10 can be deployed in the cloud, that is, cloud service, or it can be deployed on a physical server, a cluster server, a high-defense server, etc., or a server combined with blockchain.

[0050] In this embodiment, the unmanned vehicle dispatching platform 10 is capable of receiving data return request information sent by the terminal device, generating a dispatching task based on the data return request, and sending the task instruction to the unmanned vehicle 20; wherein, the data return request information includes at least the location information of the terminal device; further, the data return request information also includes the data size of the data packet to be uploaded.

[0051] The unmanned vehicle 20 refers to a vehicle that uses autonomous driving technology. Autonomous driving technology can be divided into multiple levels according to the intelligence level of autonomous driving. In this embodiment, the level of autonomous driving technology used by the unmanned vehicle 20 is not limited. Preferably, it is a low-speed unmanned vehicle with L3 or L4 technology level. The unmanned vehicle 20 has an automatic driving system and can automatically drive to a designated location. Those skilled in the art should understand that the automatic driving technology can adopt any automatic driving technology in the existing technology. The unmanned vehicle 20 includes a first wireless transmission module and a first storage module, which can receive and store data packets from a terminal device, wherein the first wireless transmission module uses a high-bandwidth wireless local area network for transmission; the unmanned vehicle 20 receives a task instruction, automatically drives to the terminal device, completes data packet transmission with the terminal device through the wireless transmission module, and stores the data packet in the first storage module.

[0052] The data upload point 30 includes a second wireless transmission module capable of receiving data packets from the unmanned vehicle 20. The second wireless transmission module uses a high-bandwidth wireless local area network for transmission. The unmanned vehicle 20 automatically travels to the data upload point 30 and transmits the data packet to the data upload point 30 via the first and second wireless transmission modules. The data upload point 30 is capable of uploading the data packet. The data upload point 30 transmits the data packet via a high-speed wired channel 40 when uploading the data packet. The number of data upload points 30 is not limited, and at least one data upload point 30 is included. It can be an autonomous driving station or stop for the unmanned vehicle 20, etc., and has the ability to upload data. This is not specifically limited here.

[0053] Preferably, the unmanned vehicle dispatch platform 10, the unmanned vehicle 20, and the data upload point 30 include an identity verification module to perform identity verification. The identity verification module can send and receive identity verification information, establish a secure connection, and create user information based on the verification information. Through identity verification, data packets can be accurately and securely transmitted and stored.

[0054] Specifically, regarding the identity authentication module of the unmanned vehicle 20, a unique vehicle identity code will be written into the chip on the vehicle side when it leaves the factory. Each time the vehicle is started, the vehicle side system will calculate the dynamic identity identification code corresponding to the current startup time based on the unique identity code plus the current time. The server establishes a secure and encrypted communication channel by verifying this dynamic identity identification code, and exchanges user information through the secure and encrypted communication channel. The encryption method is mainly the commonly used SSL.

[0055] The identity authentication module of the data upload point 30 will also have a unique identity code when the device leaves the factory. The corresponding dynamic identity identification code is calculated based on the time when the connection to the server is started. The server verifies the dynamic identity identification code and establishes an encrypted communication channel with the data upload point. The encryption method is mainly commonly used SSL, MD5, etc.

[0056] The unmanned vehicle dispatching platform 10 registers the identity codes of all devices when they leave the factory, and maintains the update of dynamic identity identification codes in the cloud according to time changes. When the vehicle or terminal device initiates identity verification, the identity authentication module will match the dynamic identity identification code library in the cloud. If the match is successful, the verification is successful. If the match fails, the verification fails. After the verification is successful, an encrypted communication channel is established.

[0057] A terminal device is a device with storage capabilities that continuously generates data. It can be monitoring equipment without fixed communication lines, data collection equipment without fixed lines, or a mobile terminal device. More specifically, it can be a mobile phone, camera, lidar, surveillance camera, or even an unmanned vehicle 20. A terminal device can issue a data return request message through a built-in module or installed application. Specifically, when a terminal device needs to upload data, it sends a data return request message to the unmanned vehicle dispatch platform 10.

[0058] The technical solution of the present invention is further described in detail below in conjunction with specific application scenarios.

[0059] refer to Figure 2-Figure 3 , which is a schematic diagram of the first application scenario provided by an embodiment of the present invention. This application scenario includes an unmanned vehicle dispatching platform 10, an unmanned vehicle 20, a data upload point 30, and a terminal device that initiates a data return request. In this application scenario, the unmanned vehicle 20 is an unmanned logistics vehicle. In other embodiments, the types of unmanned vehicles 20 include, but are not limited to, low-speed unmanned vehicles, unmanned food delivery vehicles, unmanned retail vehicles, unmanned inspection vehicles, and unmanned street sweepers. Preferably, the unmanned vehicle 20 is a low-speed unmanned vehicle with an L4 technology level.

[0060] The unmanned vehicle dispatching platform 10 receives the data return request sent by the terminal device, generates a dispatch task, and sends a task instruction to the first unmanned logistics vehicle that is currently performing a logistics delivery task and is closest to the terminal device, instructing it to proceed to perform the data return task. Preferably, the task instruction includes the size of the data packet to be uploaded. If the storage module of the unmanned logistics vehicle closest to the terminal device is insufficient, a message is sent to the unmanned vehicle dispatching platform 10. After receiving the message, the unmanned vehicle dispatching platform 10 then sends the task instruction to the nearest unmanned logistics vehicle until a suitable unmanned logistics vehicle is found to perform the task. Preferably, to ensure that the task instructions can be completed as quickly as possible and improve work efficiency, the unmanned vehicle dispatching platform 10 has a monitoring module for the memory status of the unmanned logistics vehicle, which can monitor the memory usage of the unmanned logistics vehicle in real time. Furthermore, the unmanned logistics vehicle dispatching platform 10 uses a complete set of algorithms to send instructions to the unmanned logistics vehicle that has not yet departed to perform the logistics delivery task and the data return task. In this case, the logistics delivery location where the unmanned logistics vehicle is to perform the task is closest to the terminal device. After completing the logistics delivery task, the unmanned logistics vehicle goes to perform the data return task, or first performs the data return task and then performs the logistics delivery task.

[0061] In this application scenario, unmanned logistics vehicles can perform part-time data backhaul tasks in between their main tasks to earn additional income.

[0062] refer to Figure 4-Figure 5 , which is a schematic diagram of the second application scenario provided by an embodiment of the present invention. This application scenario includes an unmanned vehicle scheduling platform 10, an unmanned vehicle 20, a data upload point 30, and a terminal device that initiates a data return request message. Furthermore, there are multiple unmanned vehicles 20, including at least two unmanned vehicles 20. Data packets can be transmitted between the two unmanned vehicles 20. Similarly, the types of unmanned vehicles 20 include but are not limited to: low-speed unmanned vehicles, unmanned logistics vehicles, unmanned food delivery vehicles, unmanned retail vehicles, unmanned inspection vehicles, unmanned sweepers, etc. The preferred unmanned vehicle 20 is a low-speed unmanned vehicle 20 with an L4 technical level.

[0063] During the automatic movement of multiple unmanned vehicles 20, the second unmanned vehicle 20 needs to go to the data upload point 30. At this time, the first unmanned vehicle 20 nearby sends a data return request message to the unmanned vehicle scheduling platform 10. The unmanned vehicle scheduling platform 10 receives the data return request sent by the terminal device, generates a scheduling task, and sends a task instruction to the second unmanned vehicle 20. The second unmanned vehicle 20 goes to the vicinity of the first unmanned vehicle 20 to transmit and dump the data packet. After completion, the second unmanned vehicle 20 goes to the data upload point 30 again. Furthermore, the unmanned vehicle scheduling platform 10 has a monitoring module for the memory status of the unmanned vehicle 20 as in the previous application scenario, which can monitor the memory usage of the unmanned vehicle 20 in real time. Preferably, the unmanned vehicle 20 also includes an information sharing module, which can share information between multiple unmanned vehicles 20, and can obtain the location information of other unmanned vehicles 20 in a timely manner, as well as the information about the next task to be performed, including the location to be performed and the task to be performed. Based on this information, the first unmanned vehicle 20 can judge and initiate a data return request to the unmanned vehicle dispatching platform 10 in a timely manner. The unmanned vehicle dispatching platform 10 sends a data return task instruction to the most suitable second unmanned vehicle 20 to perform the data return task based on a complete set of algorithms.

[0064] During mission execution, the unmanned vehicles 20 transfer and upload data to each other, implementing data relay. The unmanned vehicle dispatch platform 10, with its monitoring module for the unmanned vehicle 20's storage modules and a comprehensive set of algorithms, combined with the unmanned vehicle 20's information sharing module, can implement optimal data transfer solutions, improve work efficiency, and reduce costs, including data network fees for third-party operators.

[0065] refer to Figure 6-Figure 7, is a schematic diagram of the third application scenario provided by an embodiment of the present invention. This application scenario includes an unmanned vehicle scheduling platform 10, unmanned vehicles 20, a data upload point 30, and a terminal device that initiates a data return request message. Furthermore, there are multiple unmanned vehicles 20, including at least two unmanned vehicles 20. Data packets can be transmitted between the two unmanned vehicles 20. In this application scenario, within the first test area, the first unmanned vehicle 20 performs a test task, generating a large amount of data. Continuing to perform the task will affect data storage, requiring timely data dumping. At this time, the first unmanned vehicle 20 sends a data return request message to the unmanned vehicle scheduling platform 10. The unmanned vehicle scheduling platform 10 receives the data return request message sent by the first unmanned vehicle and, through a complete set of scheduling algorithms, sends a task instruction to a second unmanned vehicle 20 that meets the conditions to perform the data return task. The second unmanned vehicle 20 proceeds to the vicinity of the first unmanned vehicle 20 to transmit and dump the data packets. After completion, the second unmanned vehicle 20 proceeds to the data upload point 30. Similarly, in this application scenario, the types of the first and second unmanned vehicles 20 include, but are not limited to: low-speed unmanned vehicles, unmanned logistics vehicles, unmanned food delivery vehicles, unmanned retail vehicles, unmanned inspection vehicles, unmanned street sweepers, etc. Preferably, the unmanned vehicle 20 is a low-speed unmanned vehicle 20 with an L4 technology level.

[0066] In this application scenario, the second unmanned vehicle 20 can complete the task of returning data from the first unmanned vehicle 20 that is performing the test task in the intervals between tasks, which improves work efficiency and also saves data network fees of third-party operators.
