Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of self-service vehicle leasing, in particular to a method, system and device for ensuring consistency of cross-site data of self-service vehicle leasing and a storage medium. BACKGROUND

[0002] The current self-service leasing mode widely used in the market, especially in the leasing scenario of two-wheeled electric vehicles, often faces the problem of confusion of vehicle and battery ownership between sites. For example, due to the use of vehicles and batteries across sites by users, or due to the failure of the vehicle seat bucket lock, the battery may be taken away from one site and placed in the vehicle of another site. This leads to confusion of vehicle and battery ownership, bringing great challenges to operation and management, and increasing the risk of asset loss and data disorder.

[0003] The existing solution mainly relies on the vehicle central control registration and connection to the cloud server for site code information verification. However, this method often has the problem of long cold start time (usually more than 30 seconds), which seriously affects the user experience and reduces the operation efficiency of the leasing platform.

[0004] In addition, the existing self-service leasing mode also faces the problem of delay in data transmission and verification: when the user replaces the battery or changes the vehicle across sites, real-time verification of data is not good, which may lead to the situation that the ownership information of the vehicle and the battery is out of sync during the leasing and replacement process. SUMMARY

[0021] A4, the central control terminal unit of the vehicle reads the site code information of the battery BMS through the RS485 communication mode, and simultaneously reads the site code information stored in the internal storage for comparison and verification;

[0022] If the site code information of the two is consistent, the check is passed, the vehicle is activated, and the vehicle is normally ridden, and after the network connection, the related state information of the vehicle is synchronized;

[0023] If the site code information of the two is not consistent, the check is not passed, and the vehicle prompts the user with a voice "battery vehicle site code information check fails, the vehicle cannot be used".

[0057] The embodiment of the application provides a self-service vehicle leasing cross-point data consistency method, and simultaneously provides a self-service vehicle leasing cross-point data consistency management system, a self-service vehicle leasing cross-point data consistency device and a computer readable storage medium. The terms "first", "second", "third", "fourth" and the like (if any) in the specification and claims of the application and the above-mentioned drawings are used to distinguish similar objects, and do not have to be used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged under appropriate circumstances, so that the embodiments described herein can be implemented in an order other than that illustrated or described herein. In addition, the terms "include" or "have" and any variations thereof are intended to cover non-exclusive inclusion, for example, a process, method, system, product or device including a series of steps or units does not have to be limited to those steps or units clearly listed, but can include other steps or units not clearly listed or inherent to the process, method, product or device.

[0058] For ease of understanding, the specific flow of the embodiment of the application is described below, please refer to Figure 3 and Figure 4 One embodiment of the self-service vehicle leasing cross-point data consistency method in the embodiment of the application is as follows:

[0059] The self-service vehicle leasing cross-point data consistency method includes a station building initialization flow and a leasing vehicle battery taking and replacing flow. The station building initialization flow is used to initialize the information of the network point code of the terminal battery and the terminal vehicle, so that the system can read the information of the network point code of the terminal battery and the terminal vehicle for local verification during the process of the user leasing the vehicle to take the battery or replace the battery.

[0060] The station building initialization flow is as follows:

[0061] S1, after the initial installation of the battery replacement cabinet is completed, power is connected to the network to log in to the cloud server, and the information of the network point code and the name of the battery replacement cabinet is downloaded from the cloud server, the information of the network point code is unique;

[0062] S2, put all the batteries operated by the site into the battery swap cabinet, close the hatch; the battery swap cabinet prewrites the site code information downloaded from the cloud server to all the batteries put into it;

[0063] S3, take out all the batteries in the battery swap cabinet one by one, put the batteries with pre-set site code information into the vehicle to be operated, and wait for the vehicle's central control terminal unit to connect to the network;

[0064] S4, after the vehicle's central control terminal unit successfully connects to the network, log in to the cloud server and synchronize the site's site code information downloaded from the cloud server;

[0065] S5, the vehicle's central control terminal unit checks the pre-set site code information of the battery with the site code information downloaded by the vehicle, and writes the site code information into the internal storage of the vehicle's central control terminal unit after the verification is consistent;

[0066] S6, complete the initialization of the site code information of the vehicle and the battery;

[0067] The process of taking and replacing the battery of the rental vehicle is as follows:

[0068] A1, initiate a request for taking or replacing the battery of the rental vehicle through the user terminal to the cloud server, and the cloud server preliminarily verifies the legality of the rental request. After verification, the cloud server synchronizes the request for taking or replacing the battery of the rental vehicle to the site battery swap cabinet corresponding to the request;

[0069] The user terminal's request for taking or replacing the battery of the rental vehicle can be realized through a small program or APP by scanning the site battery swap cabinet two-dimensional code;

[0070] A2, after the battery swap cabinet receives the request for taking or replacing the battery of the rental vehicle, it determines whether it is a request for taking or replacing the battery. For example, in the case of replacing the battery, the original battery needs to be replaced with a full battery;

[0071] If it is a request for taking the battery of the rental vehicle, the battery swap cabinet allocates a full battery;

[0072] If it is a request for replacing the battery of the rental vehicle, get the site code information of the old battery, and after the battery swap cabinet allocates a full battery, write the site code information corresponding to the old battery into the new full battery, to ensure that the user uses the new battery to return to the original rental site code information consistent;

[0073] A3, the battery swap cabinet automatically opens the full battery hatch, the user takes out the allocated battery, closes the hatch, randomly puts the battery into a system-matched vehicle, closes the seat barrel lock on the vehicle for installing the battery, and then the vehicle's central control is automatically activated;

[0074] A4. The vehicle's central control terminal unit reads the network code information stored in the battery BMS via RS485 communication and simultaneously reads the network code information stored internally for comparison and verification.

[0075] If the network station code information of the two are consistent, the verification is successful, the vehicle is activated, and normal riding is allowed. After the network connection is established, the relevant status information of the vehicle will be synchronized. The central control terminal unit in this system has a backup battery to support it, which can avoid the cold start of the network module and speed up the uploading of status information and parameter synchronization.

[0076] If the two outlet code information are inconsistent, the verification will fail, and the vehicle will prompt the user with a voice message: "Battery vehicle outlet code information verification failed, this vehicle cannot be used."

[0077] Furthermore, as one embodiment of the present invention, in step S2 of the site initialization process, the battery swapping cabinet pre-writes the network address code information downloaded from the cloud server to all batteries placed inside, including:

[0078] The battery swapping cabinet control board communicates with the battery BMS via RS485, and writes the network code information downloaded from the cloud server into a specific register of the BMS via the MODBUS protocol.

[0079] Write the battery communication data to each compartment one by one until all batteries have been written. Once the battery writing is successful, send a confirmation message to the control board to confirm the successful writing.

[0080] As one specific embodiment, in step S5 of the site initialization process, the vehicle's central control terminal unit reads the network point code information stored in the battery BMS via RS485 communication and verifies it with the network point code information downloaded by the vehicle to determine whether the two information are consistent. If the information is consistent, the network point code information is written into the internal storage of the central control terminal unit. If the information is inconsistent, it is necessary to check whether the vehicle and battery are entered into the same network point.

[0081] In one specific embodiment, step A2 of the process for retrieving and replacing the battery in a rental vehicle may specifically include:

[0082] If it is a request to retrieve a battery from a rental vehicle, the local system verifies whether the vehicle is available for rent. Once the battery swapping station verifies the rental status, it uses an intelligent algorithm based on the battery's charge level, usage frequency, and other health indicators to allocate the battery for riding and activates the MOS switch for external battery discharge.

[0083] If it is a battery replacement request, after the battery swap cabinet checks the lease state and passes, the system needs to first obtain the user's old battery site code information from the cloud server, and then according to the distribution battery scheme of the battery taken by the rental vehicle, a full battery is distributed; At the same time, for the distributed battery, the battery swap cabinet communicates with the battery BMS through RS485 communication mode, and changes the old battery site code information to the distributed new battery, to ensure that the user uses the new battery to return to the original rental site code information.

[0084] The leaseable state refers to that the battery swap cabinet is currently idle and has a full battery for riding.

[0085] When the local check of the battery swap cabinet lease state does not pass, the specific abnormal state is prompted through voice and text, and the current lease request is ended; The purpose of setting the MOS switch is to prevent the battery from being taken out of the cabinet and misused in the case of abnormal battery lease state.

[0086] In a specific embodiment, the battery taking and battery replacement process step A4 can specifically include: after the battery site code information and the vehicle central control's own stored site code information are checked and do not pass, it is judged whether it is a rental vehicle taking battery or replacing battery;

[0087] If it is a rental vehicle taking battery, it means that the battery and vehicle site code information are incorrectly recorded during initialization, and need to be processed according to the abnormal dispatch order;

[0088] If it is a battery replacement, it means that the battery taken by the user is not put into the original site vehicle, but into the new site vehicle for battery replacement. It may be that the new site vehicle is a new vehicle, or the original vehicle of the old site has a small fault, etc., and wants to replace the vehicle; The vehicle voice prompts the user again: "Please put the battery back into the original vehicle, the system does not allow cross-site vehicle replacement".

[0089] The method for ensuring the consistency of data of the self-service rental vehicle across sites in the embodiments of the present application is described above, and the self-service rental vehicle cross-site data consistency management system in the embodiments of the present application is described below. Please refer to Figure 1 、 Figure 2 and Figures 5-8 An embodiment of the self-service rental vehicle cross-site data consistency management system in the embodiments of the present application includes:

The central control terminal unit is installed in the vehicle and is used to interact with the battery BMS (battery management system) and the battery replacement cabinet to realize synchronization and verification of the store code information. At the same time, it realizes data interaction with the user terminal, completes vehicle control, and is responsible for uploading the real-time state of the vehicle to the cloud server. The backup battery is used to avoid cold start of the networking module and accelerate state information uploading and parameter synchronization.

[0097] The terminal vehicle is a new national standard two-wheeled electric vehicle supporting remote control, GPS positioning and battery state monitoring.

[0098] The terminal battery is a lithium iron phosphate battery equipped with a BMS management system, which stores battery information and store code information, and communicates with the battery replacement cabinet and the central control terminal unit.

If the information is consistent, the network point code information is written into the internal storage of the central control terminal unit. If the information is inconsistent, it is necessary to check whether the vehicle and battery entries are for the same network point.

4. The method for ensuring data consistency across different locations for self-service rental vehicles according to claim 1, characterized in that, In step A2 of the process for picking up and replacing the battery in a rental vehicle,... If it is a request to retrieve a battery from a rental vehicle, the local system verifies whether the vehicle is available for rent. Once the battery swapping station verifies the rental status, it uses an intelligent algorithm based on the battery's charge level, usage frequency, and other health indicators to allocate the battery for riding and activates the MOS switch for external battery discharge. If it's a battery replacement request, after the battery swapping station verifies the rental status, it first retrieves the old battery's location code information from the cloud server. Then, according to the battery allocation plan for the rental vehicle, it allocates a fully charged battery. Simultaneously, for the allocated battery, the battery swapping station communicates with the battery BMS via RS485 to update the old battery's location code information into the allocated new battery, ensuring that the user's location code information remains consistent when returning to the original rental location with the new battery.

5. The method for ensuring data consistency across different locations for self-service rental vehicles according to claim 1, characterized in that, In step A4 of the process for picking up and replacing the battery in a rental vehicle, if the battery service point code information fails to be verified against the service point code information stored in the vehicle's central control system, it is determined whether the battery should be picked up or replaced in the rental vehicle. If the battery is being retrieved from a rental vehicle, it indicates that the battery and vehicle's service point code information was entered incorrectly during initialization, and it needs to be processed as an abnormal dispatch work order. If it is a battery replacement, it means that the battery retrieved by the user was not placed in the vehicle of the original service point, but in the vehicle of the new service point where the battery was replaced. The vehicle's voice prompts the user again: "Please put the battery back into the original vehicle. The system does not allow vehicle replacement at different service centers." 6. A self-service rental vehicle cross-site data consistency management system, characterized in that, include: The site initialization module is used to implement the site initialization process in the self-service rental vehicle cross-site data consistency method as described in any one of claims 1-5, and to complete the initialization of site vehicle and battery site code information; The battery removal module and battery replacement module for rental vehicles are used to implement the battery removal and battery replacement process of rental vehicles in the self-service rental vehicle cross-site data consistency method as described in any one of claims 1-5.

The self-service rental vehicle cross-site data consistency management system according to claim 6, characterized in that: It also includes a terminal vehicle, a terminal battery, a battery swapping unit, a cloud service unit, and a central control terminal unit for implementing the method for cross-site data consistency of self-service rental vehicles. The battery swapping unit includes a battery swapping cabinet, a 4G communication module, and a Bluetooth module. The battery swapping cabinet is used to store batteries, is responsible for real-time verification and updating of battery information, and communicates with the terminal vehicle to ensure that the battery and the vehicle's network code information are consistent. The battery swapping cabinet communicates with the terminal battery via RS485 communication. The cloud service unit includes a cloud server, a central brain, a leasing control center, and a user terminal. It is responsible for coordinating the interactive data processing between the battery swapping cabinet, the terminal vehicle, and the user terminal, while also managing the status monitoring of the equipment, data storage, and consistency verification of the network point code information. The central control terminal unit includes a backup battery, a GPS / BeiDou positioning terminal for intelligent vehicle control, a Bluetooth module, and a Cat1 communication module. The central control terminal unit is installed in the vehicle and is used to interact with the battery BMS and battery swapping cabinet to realize the synchronization and verification of network point code information. The backup battery is used to avoid cold start of the network module and speed up the uploading of status information and parameter synchronization.
