step S202, determining mobile hotspot information of a first target platform based on a mobile hotspot information list received in advance from a management platform, wherein the mobile hotspot information list comprises the mobile hotspot information of each platform where a target vehicle stops;
in an optional embodiment, the operation may be performed by a vehicle-mounted storage device located in the target vehicle, certainly, the operation may also be performed by another processing device associated with the target vehicle and having the processing capability, and the processing device may also be a processing device independently disposed from the target vehicle, where the vehicle-mounted storage device is described below as an example, optionally, the vehicle-mounted storage device may include (but is not limited to) a vehicle-mounted network video monitoring system (i.e., a vehicle-mounted NVR) and/or a monitoring camera connected with a storage unit, an audio-video playing device, and an advertisement media playing device, where the vehicle-mounted NVR and/or the monitoring camera connected with the storage unit, the audio-video playing device, and the advertisement media playing device are all in communication connection with the management platform through a constant-speed communication device or apparatus such as a 3G/4G/5G communication module or a high-speed communication module such as a wifi communication module; when the vehicle-mounted storage device is connected with the management platform in a mode of higher data transmission speed such as 3G/4G/5G, the vehicle-mounted storage device is used for receiving information of an operation command contained in the management platform and multimedia data with higher real-time requirement; when the vehicle-mounted storage device is connected with the management platform through a wifi communication module and other constant-speed communication modules, the vehicle-mounted storage device is used for receiving multimedia data and advertisement data which are not high in real-time requirement and uploading audio and video recording files of the vehicle-mounted storage device.
The monitoring camera connected with the storage unit is used for acquiring and storing audio and video data of the monitoring camera; the connection method may be (but is not limited to) wired connection or wireless connection.

The management platform may be a device or a virtual cloud capable of performing communication connection with the vehicle-mounted storage device through a communication network such as 3G/4G/5G/wifi, for example, a device with a data management function such as a matrix computer or a data cloud.
The mobile hotspot information comprises position information of a target site, a name and a password of a mobile hotspot of the target site, a configuration IP address of a storage device and the like.
Taking a bus as an example, when the bus on a certain route is started, the vehicle-mounted storage device of the bus receives the route information and the mobile hotspot information list of the bus, which are pre-stored in the management platform, through the communication module, so as to determine the mobile hotspot information of the first target platform.
Step S204, after the distance between the target vehicle and the first target platform is determined to be smaller than a preset threshold value, establishing connection of a mobile hotspot with a storage device of the first target platform based on the mobile hotspot information of the first target platform;
in an optional embodiment, the network connection may be established through any or a combination of 3G/4G/5G wireless communication, or through wifi wireless communication; in one example, in order to improve the signal transmission capacity, the vehicle-mounted storage device is connected with the storage device of the target station through any or a combination of 3G/4G/5G wireless communication; and for saving the flow cost, the platform storage equipment and the vehicle-mounted storage equipment are connected through wifi.
Taking a bus as an example, when the distance between the bus and a certain platform is less than or equal to 10m, the vehicle-mounted storage device establishes network connection with the storage device of the first target platform through the wifi communication module according to the pre-received mobile hotspot information list, so that data transmission is facilitated.
In step S206, data is transferred to the storage device of the first target station via the mobile hotspot.

Taking a bus as an example, when the storage device of a first target station needs to send audio and video data to the vehicle-mounted storage device, the audio and video data can be cut into a plurality of smaller data packets and sent in relay through the storage devices of a plurality of different first target stations, so that the stability and the effectiveness of data transmission are ensured; the data carrying capacity of the storage device of the first target station may be (but is not limited to) obtained by detecting in advance by the management platform and sending a detection result to the vehicle-mounted storage device, may also be obtained by detecting the storage device of the first target station in real time or at specified time intervals, or may be obtained by other methods, which is not described herein again.
Through the steps, the vehicle-mounted storage equipment of the target vehicle and the storage equipment of the first target platform establish mobile hotspot connection, so that the flow expenditure can be saved; meanwhile, the transmission speed of the short-distance mobile hotspot network is relatively stable, so that in the actual use process, the stable transmission of data can be ensured only by adjusting the data transmission speed according to actual requirements, and no additional network data service is needed, so that the traffic cost is avoided, and the problems of unstable data transmission and high traffic cost are solved.
Wherein, in an optional embodiment, after data transfer with the storage device of the first target station by the moving hotspot, the method further comprises:
step S210, feeding back a data transmission result to the management platform.
In an optional embodiment, after completing one or more data transmissions, a data transmission result of one time or a plurality of data transmissions is sent to the management platform, and then the management platform determines the quality of the data transmission according to the fed back data transmission result.
In an optional embodiment, before determining the mobile hotspot information of the first target station based on a pre-received mobile hotspot information list from the management platform, the method further comprises:
step S212, obtaining position information of each platform where the target vehicle stops;
in an alternative embodiment, the position information of each station at which the target vehicle is parked is fixed, so that (but not limited to) the position information of each station at which the target vehicle is parked can be obtained by storing the position information of each station in the vehicle-mounted storage device in advance, or can be obtained by storing the position information of each station in the management platform in advance and then sending the position information to the vehicle-mounted storage device through the wireless or wired network by the management platform.
Taking a bus as an example, a stop at which a certain bus stops is fixed within a fixed time, so that the stop position information at which the bus stops can be stored in the vehicle-mounted storage device or the management platform in advance, and then when the bus approaches a certain stop and network connection between the bus stop and the vehicle-mounted storage device needs to be established, the stop position information at which the bus stops stored in the vehicle-mounted storage device is called or the stop position information at which the bus stops stored in the management platform is transmitted to the vehicle-mounted storage device, so that the vehicle-mounted storage device obtains the stop position information at which the bus stops.
Step S214, calculating the distance between the target vehicle and each platform where the target vehicle stops according to the position information of the target vehicle and the position information of each platform where the target vehicle stops;
in an alternative embodiment, the target vehicle may (but is not limited to) locate the position of the target vehicle according to a GPS positioning system and/or a beidou positioning system and/or other satellite positioning systems or devices with positioning functions to obtain the position information of the target vehicle; the method for obtaining the position of the target vehicle may be that the vehicle-mounted storage device sends a positioning request to the device with the positioning function in real time and receives positioning information fed back by the device with the positioning function, or that the vehicle-mounted storage device sends a positioning request to the device with the positioning function at a specified time interval and receives positioning information fed back by the device with the positioning function, or that the vehicle-mounted storage device sends positioning information to the device with the positioning function and receives positioning information fed back by the device with the positioning function after the target vehicle travels a certain distance, as long as accurate obtaining of the positioning information of the target vehicle can be achieved, and details are not repeated here.
The calculation of the distance between the target vehicle and each platform at which the target vehicle is parked may be (but is not limited to) implemented by an existing navigation distance calculation technology, that is, after the vehicle-mounted storage device determines that the target vehicle is routed through the path of each platform at which the target vehicle is parked, since the position of each platform is fixed, after the position information of each platform at which the target vehicle is parked is determined, the distance between the target vehicle and each platform at which the target vehicle is parked may be obtained only by the vehicle-mounted storage device according to the position information of the vehicle-mounted storage device itself, and the calculation manner is the prior art, and is not described herein again. It should be noted that, in order to save the calculation time, the distance between the target vehicle and each platform where the target vehicle is parked may be determined while the position information of the target vehicle is obtained by using the satellite remote sensing distance measurement technology.
Further, in the process of calculating the distance between the target vehicle and each of the platforms at which the target vehicle is parked, the distance between the target vehicle and each of the platforms at which the target vehicle is parked may be calculated at one time according to a preset route, the distance between the target vehicle and each of the platforms at which the target vehicle is parked may be calculated sequentially according to a parking order, the distance between the target vehicle and the platform at which the target vehicle is parked may be calculated randomly, and the calculated distance data is assigned to the corresponding platform according to the information identifier of the platform, as long as the determination of the distance between the target vehicle and each of the platforms at which the target vehicle is parked can be achieved, which is not described herein again.
In step S216, the station closest to the target vehicle is determined as the first target station.
In an alternative embodiment, when the distance between the target vehicle and the platform is less than the predetermined threshold, the platform is determined to be the closest platform to the target vehicle, and then the platform is determined to be the first target platform. In the process of determining the platform closest to the target vehicle, the distance between the target vehicle and the platform may be (but is not limited to) determined by comparing the distance between the target vehicle and the platform with a predetermined threshold after obtaining the distance between the target vehicle and the platform, or may be determined by comparing the distance between the target vehicle and the platform obtained within a predetermined time before obtaining the distance between the target vehicle and the platform obtained within a predetermined time and then comparing the minimum value of the distance between the target vehicle and the platform obtained within a predetermined time with a predetermined threshold, as long as the determination of the platform closest to the target vehicle can be achieved.

Before data interaction between a management platform and vehicle-mounted storage equipment of a target vehicle is realized, a data interaction network between the vehicle-mounted storage equipment and the management platform needs to be established, so that the vehicle-mounted storage equipment needs to be registered on the management platform to determine the data transmission direction and the object of the management platform, generally, the vehicle-mounted storage equipment needs to send a registration request to the management platform in the registration process, and then the management platform judges whether to agree with the registration according to the registration request; wherein, the registration request includes (but is not limited to) an IP address, location information, etc. of the vehicle-mounted storage device; in an optional embodiment, to implement the fast response and management of the management platform to the vehicle-mounted storage device, the management platform and the vehicle-mounted storage device may (but are not limited to) perform real-time data transmission through a network such as 3G/4G/5G with fast data transmission efficiency, and the registration request further includes port information corresponding to the network type.
