Description

Technical Field

[0001] The present invention relates to the field of vehicle intelligent management technology, and in particular to a UWB-based automobile multi-scenario intelligent management method, a server-side intelligent management system and a vehicle-mounted UWB communication system. Background Art

[0002] Ultra Wide Band (UWB) is a wireless carrier communication technology that uses a frequency bandwidth of more than 1 GHz. Unlike other communication technology systems, UWB transmits data by using non-sinusoidal narrow pulses from nanoseconds to picoseconds, so it occupies a large range of spectrum. UWB technology mainly has four major characteristics: high bandwidth, high positioning accuracy, strong anti-interference ability and strong coexistence. First, UWB generally has a radio frequency bandwidth of more than 500 MHz, and transmits large data, up to hundreds of Mbit / s, which can usually support fast and efficient transmission of multimedia videos. Second, the high bandwidth enables it to have high-resolution time of flight (ToF), which can accurately measure the signal arrival time to provide more accurate distance and location information. Therefore, the distance resolution capability of UWB technology is stronger than other traditional technology paths, especially in complex environments, its location accuracy is 2 orders of magnitude higher than WiFi (WIreless Fidelity, mobile hotspot) and Bluetooth, and it also has the characteristics of large capacity, low latency and low power consumption. Third, the UWB short pulse signal is very short, and the probability of signal collision is very small. Even if a signal collision occurs, the UWB signal can be easily identified because of its high signal-to-noise ratio, which can effectively combat spatial white noise interference and multipath interference. Fourth, the power spectrum density of UWB is very low, generally less than -41.3dBm / MHz, and the vehicle-side frequency band is usually 6 to 8GHz. Therefore, the probability of interference and conflict between UWB and other existing wireless technologies on the vehicle side is greatly reduced, and the coexistence is stronger.

[0003] From the analysis of the current status of UWB automotive applications, UWB technology, with its high security, is currently mainly used to solve the relay attack problem that may be encountered by automotive digital keys. In the field of new automotive technology applications, the third-generation digital key is a full-stack integrated product that combines three wireless communication technologies: UWB, Bluetooth Low Energy (BLE) and Near Field Communication (NFC). In addition, UWB technology is also gradually being used in automotive short-range communication application scenarios, such as the increasingly rich automotive media data.

[0004] In terms of smart car management technology, with the continuous iteration and upgrading of new technologies and the evolution of Over the Air (OTA) technology, functions such as remote start, remote management, valet parking, and smart car search have gradually been favored by car customers, which not only enhances the technological sense of the product, but also facilitates the effective management of the car by car owners. Limited by the communication technology system and bandwidth capacity, most of the current remote car management only supports the observable and controllable data at the message level such as remote vehicle condition query and remote start, and has not yet achieved more intuitive video-level data and process observable and controllable. For example, although some parking lots currently have car search technology, they are limited by low-precision positioning capabilities and low-bandwidth data transmission carrying capacity, and most of them are one-to-one parking space number displays, and car owners usually still find it difficult to find their cars.

[0005] In terms of automobile consumer payment technology, currently, with the help of online payment technologies such as WeChat, Alipay, and digital RMB, quick online payment can be achieved, but it usually needs to rely on customer mobile terminals, watches and other wearable devices to scan codes or pay in the near field, which is still a touch payment. For example, although most parking lots have achieved unattended operation, parking payment still requires various small programs and APPs (Applications), which still has a certain impact on the daily travel efficiency of car users; although the national highways have opened full-automatic toll collection systems (Electronic Toll Collection, ETC) non-stop toll lanes, the car speed still needs to be below a certain range, and peak traffic will still cause a certain degree of congestion. The key to the above status quo is that the current automobile consumer payment systems have failed to achieve touchless payment, and payment efficiency should be further improved based on new technologies.

[0006] Currently, some patent documents have disclosed the use of UWB technology for high-bandwidth communication data transmission and payment scenarios, but there are few related patent technologies in the automotive field, especially using it as a contactless payment function in automotive scenarios. Related patent documents have not yet been disclosed. For example, a Chinese patent document with a publication date of April 4, 2023 and a publication number of CN115907752A proposes a UWB-based payment method and system, which mainly establishes a UWB communication connection between the cash register terminal and the payment terminal in the designated area based on the UWB payment method; a Chinese patent document with a publication date of September 16, 2022 and a publication number of CN115065924A proposes a high-speed communication UWB positioning system and a high-speed communication UWB access control system, but it mainly discloses specific technologies and transmission solutions for improving the transmission speed of positioning signals, and has not formed a systematic solution for multi-scenario intelligent management of automobiles; a Chinese patent document with a publication date of April 4, 2023 and a publication number of CN115909518A proposes a method for implementing parking payment for unmanned vehicles based on UWB positioning. Although the parking fee collection method is related to UWB technology and payment technology in the automotive field, it mainly uses UWB technology for communication and has not formed a systematic solution for multi-scenario intelligent management of automobiles. Summary of the invention

[0007] The purpose of the present invention is to provide a UWB-based automobile multi-scenario intelligent management method and system to solve the problem that the automobile intelligent management technology in the prior art cannot achieve remote monitoring, accurate vehicle search and contactless payment at the video level.

[0008] In order to achieve the above object, the technical solution adopted by the present invention is as follows:

[0009] In the first aspect, the present invention provides a UWB-based automobile multi-scenario intelligent management method, which is applied to a server-side intelligent management system, and the intelligent management method includes: real-time reception of vehicle location information sent by a vehicle-mounted UWB communication system through a UWB communication base station at an application scenario end; the application scenario end is a parking lot, toll station, gas station, charging station or service area; regular sending of remote monitoring instructions to the vehicle-mounted UWB communication system, and the remote monitoring instructions are used to instruct the vehicle-mounted UWB communication system to generate vehicle remote monitoring information; real-time reception of vehicle remote monitoring information sent by the vehicle-mounted UWB communication system through the UWB communication base station, and the vehicle remote monitoring information includes audio data around the vehicle and / or video data around the vehicle.

[0010] According to the above technical means, the server-side intelligent management system is based on the existing UWB communication connection between the vehicle-mounted end and the application scenario end, and completes the interaction with the vehicle-mounted end through the UWB communication base station, thereby realizing remote monitoring of the vehicle location and the vehicle's surrounding environment. Compared with the prior art that only supports data monitoring at the message level such as remote vehicle condition query and remote start, the present invention can obtain more intuitive video-level data, thereby realizing observable and controllable real-time processes around the car. Moreover, the present invention utilizes the ultra-wideband capability of UWB technology to transmit video data around the vehicle through the UWB communication base station, solving the problem of low efficiency of multimedia video data transmission.

[0011] Furthermore, the smart management method may also include: generating a vehicle search instruction based on a user's request operation; retrieving vehicle location information, parking space number and video data around the vehicle according to the vehicle search instruction, wherein the parking space number is generated by matching the vehicle location information on the application scenario side; and generating three-dimensional visual vehicle search path navigation information from the user location to the vehicle location in combination with digital twins and path planning based on the vehicle location information, parking space number and video data around the vehicle.

[0012] According to the above technical means, the server-side intelligent management system retrieves the internally stored vehicle location, parking space number and video around the vehicle, and generates a three-dimensional path planning from the user's location to the vehicle's location, which derives the parking lot intelligent and precise car search service. Since the vehicle location stored in the server-side intelligent management system is provided by the vehicle-mounted UWB communication system, the high-precision characteristics of UWB technology can achieve high-precision positioning of the car's location.

[0013] Furthermore, the smart management method may also include: generating a consumption charging instruction based on vehicle consumption information received from the UWB communication base station at the application scenario end; wherein the vehicle consumption information is generated by the application scenario end by matching the UWB communication code when the user drives the vehicle into the consumption payment environment of the application scenario end; sending the consumption charging instruction to the vehicle-mounted UWB communication system, and the consumption charging instruction is used to instruct the vehicle-mounted UWB communication system to communicate with the UWB communication base station to complete the vehicle consumption payment.

[0014] According to the above-mentioned technical means, when the user drives the vehicle into the consumption payment environment of the application scenario, the consumption charging instruction is sent to the UWB communication system on the vehicle side through the service-side intelligent management system, prompting the vehicle side to actively complete the contactless payment with the application scenario side (such as parking lots, gas stations, etc.), thereby improving the efficiency of car payment.

[0015] Furthermore, the smart management method may also include: retrieving traffic data information matching the license plate recognition information based on the license plate recognition information received from the UWB communication base station at the application scenario end; wherein the traffic data information includes the license plate, vehicle model, user information and UWB communication code; and sending the UWB communication code to the UWB communication base station.

[0016] According to the above-mentioned technical means, when the UWB communication base station in the application scenario end cannot directly complete the vehicle information matching (for example, a communication failure occurs), the UWB communication ID and other tag information stored in the server-side intelligent management system can be retrieved and sent to the application scenario end, so that the UWB communication base station and the vehicle-mounted UWB communication system can successfully complete the communication, and then the vehicle-mounted end can complete the contactless payment with the application scenario end (such as parking lots, gas stations, etc.), avoiding a certain degree of congestion on the application scenario end due to the inability to deduct fees smoothly.

[0017] Furthermore, the smart management method may also include: receiving fee settlement information sent by the UWB communication base station, wherein the fee settlement information is generated after the application scenario end completes the fee settlement through the deduction confirmation instruction sent by the vehicle-mounted UWB communication system.

[0018] Based on the above technical means, the server-side intelligent management system obtains the fee settlement information after car consumption by interacting with the UWB communication base station in the application scenario (such as a parking lot), which is beneficial for users to know and check the consumption status at any time later.

[0019] In the second aspect, the present invention provides a UWB-based automobile multi-scenario intelligent management method, which is applied to the vehicle-mounted UWB communication system. The intelligent management method includes: when the vehicle-mounted UWB communication system establishes a UWB communication connection with the UWB communication base station in the application scenario end, the vehicle location information is sent in real time to the server-side intelligent management system through the communication base station; the application scenario end is a parking lot, toll station, gas station, charging station or service area; according to the remote monitoring instructions received from the server-side intelligent management system, vehicle remote monitoring information is generated; the vehicle remote monitoring information includes audio data around the vehicle and / or video data around the vehicle; the vehicle remote monitoring information is sent to the server-side intelligent management system through the UWB communication base station.

[0020] According to the above technical means, the vehicle-mounted UWB communication system indirectly sends the vehicle positioning data and remote monitoring information to the service-end intelligent management system through communication with the UWB communication base station, thereby realizing automobile service functions such as precise automobile positioning and environmental remote monitoring. Compared with the existing technology that the vehicle-mounted UWB communication system realizes functions such as automobile digital keys and automobile short-range communication, this application applies the vehicle-mounted UWB communication system to automobile service scenarios, and uses UWB communication to transmit positioning data and vehicle surrounding video data, solving the problem of low efficiency in multimedia video data transmission.

[0021] Furthermore, the smart management method may include: when a user drives a vehicle into the consumption payment environment of the application scenario end, receiving a consumption charging instruction sent by the UWB communication base station or the service-end smart management system, the consumption charging instruction is generated by the application scenario end or the service-end smart management system based on the vehicle consumption information, and the vehicle consumption information is generated by the application scenario end by matching the UWB communication code; after verifying the consumption charging instruction, generating a deduction confirmation instruction; sending the deduction confirmation instruction to the UWB communication base station, the deduction confirmation instruction is used to instruct the application scenario end to complete the fee settlement.

[0022] According to the above technical means, when the user drives the vehicle into the consumption payment environment of the application scenario, the vehicle-mounted UWB communication system sends a deduction confirmation instruction to the vehicle-mounted UWB communication system, realizing the non-contact payment between the vehicle-mounted end and the application scenario end (such as parking lots, gas stations, etc.), thereby improving the efficiency of automobile payment. Moreover, before generating the deduction confirmation instruction, the vehicle-mounted UWB communication system effectively verifies the consumption charging instruction, thus avoiding the occurrence of erroneous deductions on the application scenario end.

[0023] Furthermore, the intelligent management method also includes: after sending the deduction confirmation instruction, the vehicle consumption information and the deduction confirmation information can be transmitted to the on-board computer through the vehicle communication module.

[0024] According to the above-mentioned technical means, the vehicle-mounted UWB communication system transmits vehicle consumption information and deduction confirmation information to the on-board computer through the vehicle communication module, which is beneficial for users to know the consumption situation at the first time during driving.

[0025] In the third aspect, the present invention provides a server-side intelligent management system, which includes a processor, a switch, and a memory connected to the processor; the memory stores computer execution instructions; the switch is used to complete data transmission between the communication base station in the application scenario and the server-side intelligent management system; the processor executes the computer execution instructions stored in the memory to implement the above-mentioned intelligent management method.

[0026] Based on the above-mentioned technical means, the service-side intelligent management system derives automobile-related services within the scope of the application scenario through interaction with the UWB communication base station and the vehicle-mounted UWB communication system, such as contactless payment of parking fees in parking lots, contactless payment of fuel fees at gas stations, intelligent and precise car search in parking lots, and monitoring of the environment around vehicles.

[0028] Based on the above-mentioned technical means, the vehicle-mounted UWB communication system uses UWB technology as a high-bandwidth communication data transmission and payment scenario, making it more efficient and convenient for users to use car services and consume.

[0048] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0049] Embodiment 1

[0050] The first embodiment of the present invention provides a UWB-based automobile multi-scenario intelligent management method, such as Figure 1 As shown, the executor of the embodiment of the present application is a server-side intelligent management system, and the intelligent management method includes the following steps.

[0051] Step S101: receiving in real time the vehicle location information sent by the vehicle-mounted UWB communication system through the UWB communication base station in the application scenario. Here, the role of the UWB communication base station is to establish a UWB communication relationship with the vehicle-mounted UWB communication system, so that the UWB data sent by the vehicle-mounted UWB communication system can be forwarded to the service-end intelligent management system.

[0052] Step S102: Generate a remote monitoring command and send the remote monitoring command to the vehicle-mounted UWB communication system at regular intervals. Here, the remote monitoring command is used to instruct the vehicle-mounted UWB communication system to generate vehicle remote monitoring information. The application scenario end is a parking lot, toll station, gas station, charging station or service area.

[0053] Step S103: receiving in real time the vehicle remote monitoring information sent by the vehicle-mounted UWB communication system via the UWB communication base station, wherein the vehicle remote monitoring information includes the vehicle surrounding audio data and / or the vehicle surrounding video data.

[0054] Through the above steps, when the user drives the vehicle into the application scenario, the server-side intelligent management system can obtain service data such as vehicle location and monitoring audio and video in real time, and can manage and operate these service data in the background, and display them to the user after processing, so that the user can remotely monitor the vehicle.

[0055] Furthermore, in this embodiment, the smart management method may also include step S104 and step S106.

[0056] Step S104: Generate a vehicle search instruction based on the user's request operation.

[0057] Step S105: according to the vehicle search instruction, retrieve the vehicle location information, parking space number and the video data around the vehicle, wherein the parking space number is generated by the application scenario end by matching the vehicle location information.

[0058] Step S106: Generate three-dimensional visual vehicle-finding path navigation information from the user location to the vehicle location based on the vehicle location information, parking space number, and video data around the vehicle, combined with digital twins and path planning.

[0059] Through the above steps, when the user needs to obtain the location of the application scenario (for example, a parking lot) and realize the smart car search service, he can send a request to the server-side smart management system. The server-side smart management system can generate a car search instruction based on the request operation and form a corresponding three-dimensional path planning.

[0060] Furthermore, in this embodiment, the smart management method may also include steps S107 to S109.

[0061] Step S107: When the user drives the vehicle into the consumption payment environment of the application scenario, the vehicle consumption information sent by the UWB communication base station is received.

[0062] Here, vehicle consumption information is generated by matching the UWB communication code on the application scenario side when the user drives the vehicle into the consumption payment environment on the application scenario side. The UWB communication code is generated after the vehicle-mounted UWB communication system establishes a UWB communication connection with the UWB communication base station in the application scenario side.

[0063] If the UWB communication system on the vehicle fails to establish a UWB communication connection with the UWB communication base station in the application scenario due to hardware communication failure, resulting in the inability of the application scenario to directly complete the vehicle information matching, the communication between the UWB communication base station and the vehicle-mounted UWB communication system needs to be achieved by the service-side smart management system retrieving the UWB communication ID stored internally. Furthermore, the process of receiving vehicle consumption information sent by the UWB communication base station may include but is not limited to the following sub-steps:

[0064] Sub-step S1071: receiving the license plate recognition information sent by the UWB communication base station. The license plate recognition information can be obtained by a camera device set in the application scenario end.

[0065] Sub-step S1072, retrieve the traffic data information matching the license plate recognition information, and send the UWB communication code to the UWB communication base station. The traffic data information includes the license plate, vehicle model, user information and UWB communication code, etc. The traffic data information is stored in the server-side intelligent management system.

[0066] Sub-step S1073, receiving vehicle consumption information sent by the UWB communication base station.

[0067] Step S108: Generate a consumption charging instruction based on the vehicle consumption information.

[0068] Step S109: Send the consumption charging instruction to the vehicle-mounted UWB communication system, wherein the consumption charging instruction is used to instruct the vehicle-mounted UWB communication system to communicate with the UWB communication base station to complete the vehicle consumption payment.

[0069] Through the above steps, when the user drives the vehicle to the consumption payment environment of the application scenario, the service-side intelligent management system can send consumption and charging instructions to the vehicle-mounted UWB communication system, prompting the vehicle-mounted end to actively complete the non-sensing payment with the application scenario end (such as parking lots, gas stations, etc.), thereby improving the efficiency of automobile payment. When the UWB communication base station in the application scenario end cannot directly complete the vehicle information matching, it can also retrieve the UWB communication ID and other tag information stored in the service-side intelligent management system and send it to the application scenario end, so that the UWB communication base station and the vehicle-mounted UWB communication system can successfully complete the communication, avoiding a certain degree of congestion caused by the inability to smoothly deduct fees at the application scenario end.

[0070] The implementation environment of the embodiment of the present application may include at least one terminal and a server, and the method is executed on the terminal or the server respectively. The terminal and the server can be connected in communication to realize the interactive transmission of information. Among them, the terminal can be any electronic product that can interact with the user through one or more methods such as keyboard, touchpad, touch screen, voice interaction, etc., such as PC (Personal Computer), PPC (Pocket Personal Computer), tablet computer, etc.

[0071] The server can be a single server or a server cluster composed of multiple servers. It can also be a cloud server that provides basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communications, middleware services, domain name services, security services, CDN (Content Delivery Network), as well as big data and artificial intelligence platforms.

[0073] The second embodiment of the present invention provides a UWB-based automobile multi-scenario intelligent management method, such as Figure 2 As shown, the executor of the embodiment of the present application is a vehicle-mounted UWB communication system, and the intelligent management method includes the following steps.

[0074] Step S201: When the vehicle-mounted UWB communication system establishes a UWB communication connection with the UWB communication base station in the application scenario, the vehicle location information is sent to the server-side intelligent management system in real time through the UWB communication base station.

[0076] Step S203: Generate vehicle remote monitoring information according to the remote monitoring instruction received from the server-side intelligent management system, wherein the vehicle remote monitoring information includes audio data and / or video data around the vehicle.

[0077] Step S204: Send the vehicle remote monitoring information to the server-side intelligent management system via the UWB communication base station.

[0078] Through the above steps, the vehicle-mounted UWB communication system indirectly sends the vehicle positioning data and remote monitoring data to the server-side intelligent management system through communication with the UWB communication base station, so that users can manage and operate the vehicle positioning data and remote monitoring data more intuitively and conveniently through the server-side intelligent management system.

[0079] Furthermore, in this embodiment, the smart management method may also include steps S205 to S207.

[0080] Step S205: When the user drives the vehicle into the consumption payment environment of the application scenario, the consumption charging instruction sent by the UWB communication base station or the service-side intelligent management system is received.

[0081] Among them, the consumption charging instruction is generated by the application scenario end or the service end intelligent management system based on the vehicle consumption information; the vehicle consumption information is generated by the application scenario end by matching the UWB communication code.

[0082] Step S206: After verifying the consumption charging instruction, generate a deduction confirmation instruction.

[0083] Step S207: Send a charge confirmation instruction to the UWB communication base station, where the charge confirmation instruction is used to instruct the application scenario end to complete the fee settlement.

[0084] Through the above steps, the vehicle-mounted UWB communication system sends a deduction confirmation instruction to the vehicle-mounted UWB communication system, realizing the non-contact payment between the vehicle-mounted end and the application scenario end (such as parking lots, gas stations, etc.), thereby improving the efficiency of automobile payment. Moreover, before generating the deduction confirmation instruction, the vehicle-mounted UWB communication system effectively verifies the consumption charging instruction, thus avoiding the occurrence of erroneous deductions on the application scenario end.

[0085] Furthermore, in step S207, after sending the deduction confirmation instruction, the vehicle-mounted UWB communication system can also transmit the vehicle consumption information and deduction confirmation information to the driving computer through the vehicle communication module, so that the user can know the consumption situation at the first time during driving.

[0134] The sixth embodiment of the present invention provides a car multi-scenario intelligent management and contactless payment system based on UWB technology, which mainly includes a vehicle-side UWB communication system, a UWB communication base station, a server-side intelligent management system and a UWB payment system.

[0135] like Figure 6 and Figure 7As shown in the figure, the vehicle-side UWB communication system is mainly composed of multiple UWB anchor points installed on the vehicle body, a UWB control module and a UWB communication module. According to the performance requirements of different manufacturers, the layout form and number of UWB anchor points in the vehicle-side architecture are different. This embodiment takes the layout of 5 anchor points as an example. Figure 7 As shown, anchor points 1 to 4 are arranged outside the vehicle, anchor point 1 is arranged at the left front of the vehicle, anchor point 2 is arranged at the left rear of the vehicle, anchor point 3 is arranged at the right front of the vehicle, anchor point 4 is arranged at the right rear of the vehicle, and anchor point 5 is arranged on the roof in the middle of the vehicle.

[0136] The UWB communication control module mainly controls the operation and management of the vehicle-side UWB ID (full name: Identity document, referring to the ID card identification number, code, etc.), interacts with the on-board communication module, and retrieves the vehicle-side audio and video data of the on-board audio and video module, and other communication functions and logical processing.

[0137] The UWB communication module is an interface module for automobiles based on UWB communication. It is mainly responsible for communicating and transmitting positioning data with various UWB communication base stations in different environments where the automobile is located.

[0138] In the vehicle-side UWB communication system architecture, the vehicle communication module is a traditional vehicle communication module, which mainly carries common communication application functions of the vehicle, such as interconnection with mobile terminals and other vehicle machines. The vehicle audio and video module is a vehicle audio and video operation management module, which is connected to the vehicle cameras installed at various positions of the vehicle to manage and execute the vehicle audio and video data. For example, the vehicle audio and video module can transmit the audio and video data around the vehicle body collected in real time by the vehicle surround camera. The UWB control module and the vehicle communication module, the vehicle audio and video module, etc. realize effective communication based on in-vehicle communication technologies such as CAN bus and Ethernet.

[0139] The UWB communication base station is an environmental infrastructure that supports the use of UWB technology in various application scenarios. It has a similar function to 4G / 5G and other ground base stations. It is mainly used to establish one-to-one communication with the car's UWB communication module through radio frequency wireless communication technology when a car with UWB function enters the environment and implements UWB-related scene functions, so as to realize application services after the communication is established.

[0140] The UWB payment system is a device that supports UWB technology in consumption scenarios. It is mainly used to complete deductions after a UWB-enabled car enters the environment and confirms consumption.

[0141] The service-side intelligent management system (hereinafter referred to as the intelligent management system or system) is mainly based on UWB communication and positioning data between the vehicle side and the field side (that is, the application scenario side), and derives automobile-related services within its jurisdiction, such as contactless payment of parking fees in parking lots, contactless payment of fuel fees at gas stations, intelligent and accurate car search in parking lots, and monitoring of the environment around vehicles.

[0142] like Figure 6 and Figure 8 As shown, the smart management system is mainly composed of switches, data management platforms, application service platforms, security management subsystems, traffic management subsystems, cloud platforms and mobile terminal modules.

[0143] The switch is mainly used to build data transmission between UWB base stations and intelligent management systems.

[0144] The application service platform is the front-end execution platform of the system application service solution and an external data interaction platform. The main function of the platform is to complete relevant services for the car side based on UWB data. Users can complete the development of different functions based on their needs.

[0145] The data management platform mainly stores the relevant data transmitted from the UWB communication base station to the system by the switch and the relevant service data during the service execution of the application service platform.

[0146] The security management subsystem provides data security services for the security management of data sent out by the data management platform and before data is uploaded to the cloud.

[0147] The functional attributes of the cloud platform are consistent with those of the data management system. It is mainly used to store UWB communication and positioning data and corresponding application service data so that mobile terminals and platforms outside the vehicle and management system can access relevant data.

[0148] The traffic management subsystem mainly stores traffic data information such as car models, license plates and owner information. When the UWB communication base station and the vehicle-side UWB communication module need to query the car owner information, model, license plate information, etc., the application service platform will send relevant information retrieval instructions to the traffic management system to complete the retrieval and feedback of the information stored in the traffic management subsystem.

[0149] The mobile terminal module is a mobile terminal such as a car user's mobile phone, which can realize conventional control of the car-side UWB communication module, vehicle communication module and application service platform, such as UWB communication module ID signaling interface switch, application service platform related data query, etc. At the same time, the mobile terminal module can receive relevant data sent by the cloud platform system and the vehicle communication module, allowing users to manage and operate car data and service data more intuitively and conveniently.

[0150] The operational process of realizing automobile positioning and remote environmental monitoring through the automobile multi-scenario intelligent management in this embodiment includes the following steps.

[0151] Step S601: After the car enters a parking lot with a UWB communication base station, a communication and positioning relationship is established between the parking lot UWB base station and the vehicle-side UWB communication module. Relying on the high-precision characteristics of UWB technology, high-precision real-time positioning of the car position and parking space number can be achieved.

[0152] Step S602: After the parking lot UWB communication base station establishes a communication relationship with the vehicle-side UWB communication module, the UWB communication base station sends the vehicle-side location information through the switch and stores it in the data management platform.

[0153] Step S603: The security management subsystem securely processes the vehicle location data information stored in the data management platform and sends it to the cloud management platform, and the application service platform obtains relevant data at the same time.

[0154] Step S604: After the car user sends a remote monitoring instruction of the car environment data to the vehicle-side UWB communication module through a mobile terminal that also has UWB communication technology, the UWB control module sends an execution monitoring and data transmission instruction to the vehicle-mounted audio and video module.

[0155] At this time, the on-board cameras of the car monitor the audio and video data around the car in real time, and transmit it to the UWB base station of the parking lot through the UWB communication on the car side, and further store it in the data management platform for local monitoring and analysis in the parking lot. At the same time, it is uploaded to the cloud platform for car users to realize remote status and environmental monitoring based on mobile terminals to ensure the safety of the car environment. At the same time, it can realize on-site audio and video data verification after the car is damaged by a third party and other reasons.

[0156] Step S605: When the car user sends a car search instruction to the parking lot based on the mobile terminal before using the car, the application service platform sends the car's precise satellite information to the mobile terminal. At the same time, based on technologies such as digital twins and path planning, the application service platform combines the three-dimensional spatial data of the parking lot to complete the three-dimensional car search path navigation from the car user's location to the car parking space, making the car search intuitive and efficient, and solving the current bottleneck problem of finding cars in parking lots.

[0157] The operational process of realizing contactless payment of automobiles through the multi-scenario intelligent management of automobiles in this embodiment includes the following steps.

[0158] Step S701: When a car enters a car consumption payment environment (such as a parking lot entrance or exit, a gas station, a highway toll station, etc.), after the consumption is completed, the UWB communication base station or the car user's mobile terminal set in the environment sends a consumption charging instruction and consumption details to the UWB communication module on the vehicle side.

[0159] Step S702: After receiving and verifying the instruction, the vehicle-side UWB communication module feeds back the deduction confirmation instruction and bound consumer account information to the UWB communication base station to further complete the deduction.

[0160] Step S703: After the vehicle-side UWB communication module feeds back a confirmation instruction to the UWB communication base station, the consumption information and confirmation instruction information are synchronously transmitted to the vehicle communication module.

[0161] Step S704: After receiving the confirmation instruction from the vehicle-side UWB communication module, the field-side UWB communication base station sends the execution instruction to the UWB execution module, and the UWB execution module carries out operations such as lifting the barrier at the parking lot exit and lifting the barrier after charging without stopping at the highway toll station.

[0162] Step S705: After the UWB execution module completes the instruction operation, the fee settlement system set up in the environment completes the display of fee consumption details and other information.

[0163] Step S706: After the deduction is completed and the relevant execution operations are implemented, the application service platform pushes the consumption information to the mobile terminal directly or through the cloud platform so that the car user can know the consumption situation in time.

[0164] Step S707: If the vehicle owner's mobile terminal and the UWB base station at the field end cannot directly complete the vehicle information matching, the camera device installed at the field end recognizes the vehicle's license plate and other information by taking a photo.

[0165] Step S708: The application service platform retrieves and compares vehicle information from the traffic management system through the security management system to obtain tag information such as the UWB communication ID of the car user registered in the traffic management system.

[0166] Step S709: After the application service platform completes the retrieval of the UWB communication ID (that is, the UWB communication code), it completes the full process command execution and physical operation of steps S701 to S706, thereby realizing contactless payment based on UWB technology.

[0167] The obvious equivalent changes or transformations, readjustments and substitutions made by those skilled in the art on the basis of the present invention, or directly or indirectly applied in other related technical fields, are all within the protection scope of the present invention. Therefore, although the present invention is described in detail through the above embodiments, the present invention is not limited to the above embodiments, and may include more other equivalent embodiments without departing from the concept of the present invention, and the scope of the present invention is determined by the scope of the appended claims.
