In view of this, the present invention aims to propose an advertising interconnection system for hub rotation imaging, as specified in any one of claims <NUM> to <NUM>, which can efficiently and practically realize advertising interconnection of hub imaging, and meet multiple practical needs.

The accompanying drawing constituting a part of the present invention is used for providing a further understanding of the present invention, and the schematic embodiments of the present invention and the descriptions thereof are used for interpreting the present invention, rather than constituting improper limitations to the present invention. In the drawing:
<FIG> is a schematic diagram of an advertising interconnection system for hub rotation imaging according to the present invention.

It should be noted that the embodiments in the present invention and the features in the embodiments can be combined with each other without conflicts.

The technical solutions of the present invention will be described clearly and completely with reference to the accompanying drawing and in combination with the embodiments. Apparently, the described embodiments are part of, not all of, the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without any creative effort shall fall within the protection scope of the present invention.

In advertising interconnection system for hub rotation imaging according to an embodiment of the present invention will be described with reference to <FIG> and in conjunction with the embodiments.

An advertising interconnection system for hub rotation imaging mainly comprises a server, a base station, and a communication module installed on a vehicle hub.

The communication module comprises a long-distance wireless communication module and a low-power short-distance communication module. In particular, in terms of a vehicle, a long-distance wireless communication module is installed on at least one hub of each vehicle, a low-power short-distance communication module is installed on each hub of each vehicle, and each communication module is driven by a processor unit. The long-distance wireless communication module of each vehicle establishes a connection with the server through the base station to receive instructions and exchanges data. The low-power short-distance communication module on the hub where the long-distance wireless communication module of each vehicle is located establishes a connection with the low-power short-distance communication module on each remaining hub of the vehicle to exchange data.

The server can receive various sensor data uploaded by the communication module of each vehicle, and infer data such as driving information and location information of the vehicle; the server can also issue single or multiple instructions/transfer files to the communication module of each vehicle individually or in batches; and the server can also simultaneously issue the same instruction or file to the communication modules of multiple vehicles.

In some embodiments, an advertising interconnection system for hub rotation imaging, referring to <FIG>, comprises a network server, a base station, and a vehicle installed with at least one long-distance wireless communication module.

Several hubs of each vehicle form a set of nodes, a long-distance wireless communication module and a low-power short-distance communication module are installed on one of the hubs, and only low-power short-distance communication modules are installed on the remaining hubs. Taking a vehicle installed with four wheels as an example, the four wheels are a set of nodes, and thee of the hubs are set as slaves equipped with low-power short-distance communication modules, such as Bluetooth communication modules, and ZigBee (a wireless network protocol for low-speed and short-distance transmission); the other hub is set as the host, which is equipped with a short-distance communication module (such as Bluetooth, or ZigBee) and a long-distance wireless communication module, such as a general ground mobile <NUM>/<NUM>/<NUM>/NB-IoT communication module; and the low-power short-distance communication modules and the long-distance wireless communication module are driven by a processor unit, such as an ARM (Advanced RISC Machines, a <NUM>-bit reduced instruction set processor architecture) kernel single-chip microcomputer and the like with the function of driving the low-power short-distance communication modules and the long-distance wireless communication module. In the set of nodes of this vehicle, the host and the other three slaves communicate and interact through respective low-power short-distance communication modules. The host is responsible for collecting various data or demand information that each slave needs to report to the server, such as sensor data of the hubs, and distribute the data or instructions obtained from the server to each slave. The host in the set of nodes communicates with the base station through the long-distance wireless communication module, establishes a connection with the server, reports the information of the host itself and the information collected from each slave to the server, and acquires data information or instruction information issued by the server.

The server on the network side establishes a connection with the long-distance wireless communication module of the host of each vehicle through the base station to collect data information and issue data and instruction information. The server can obtain the sensor information of the hubs, and calculate the running status and geographic location of the hubs, and the like. According to actual needs, the server can send instructions and transfer files to the hubs in batches. The instructions and files can be single or multiple. The server can also simultaneously issue the same instructions/files to multiple sets of nodes.

The server can automatically control the multiple sets of nodes according to system settings, for example, set the hubs of each vehicle in a designated area to play the same video content at the same time; or set all of the hubs of vehicles on a highway to display notification content at the same time, and the like.

In some embodiments, one or more slaves in a vehicle can also be set as a backup host, especially in a vehicle scenario such as a heavy-duty truck, a proper amount of backup can ensure the reliability of the Internet-of-vehicles system. The backup host is the same as the host, equipped with a low-power short-distance communication module and a long-distance wireless communication module. When the host is normal, the backup host works in a slave mode. Like other slaves, the backup host reports sensor data to the host through the low-power short-distance communication module thereof, and receives distributed data and instructions from the host, and the like.

When the host in the set of nodes of the vehicle fails to perform host functions, the backup host is switched to a host mode and becomes a new host which establishes a communication connection with the network side, reports data and receives data instructions and the like by the long-distance wireless communication module thereof; and collects data from each slave and distributes data instructions to each slave by the low-power short-distance communication module thereof.

Host failures are roughly divided into two levels, wherein the second-level failure is that the long-distance wireless communication module fails and cannot communicate. At this time, the original host is switched to work in the slave mode, and communicates with the new host through its short-distance communication module and the first-level failure is that both the long-distance wireless communication module and the low-power short-distance communication module fail and cannot communicate normally. At this time, the communication function of the original host is down, and the new host reports the status of the first-level failure of the original host to the server through the long-distance wireless communication module.

When the original host that fails is restored, the new host and the original host can determine, by means of a negotiation mechanism, whether to maintain the current working state, restore to the original working state, or restore to the original working state after a certain time.

When the original host that fails is restored, the original host can also report the failure restoration to the server through its long-distance wireless communication module, and then the server determines which node (the original host or the current host) in the set of nodes serves as next host.

In some embodiments, one or more slaves in a vehicle are set as a backup host(s). The backup host is the same as the host, equipped with a low-power short-range communication module and a long-range wireless communication module. The switching between the host and the backup host is no longer on the basis of whether the current host fails, the server sets the specific working mechanism of the main/backup host, and directs the switching of working modes of the current host and the backup host through the issuance of instructions.

This embodiment can enhance the system reliability of the Internet of vehicles.

The configurations of the above embodiments can be flexibly arranged according to the emphasis of actual applications to meet different practical needs.

In addition, the hub nodes are simplified, and the nodes on each vehicle are controlled hierarchically.
