While embodiments of the present application are illustrated in the accompanying drawings, it should be understood that the present application may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

It should be noted that the embodiments and features of the embodiments may be combined with each other without conflict.

The present invention will be described in detail below with reference to the embodiments with reference to the attached drawings.

Referring to fig. 1, a schematic flow chart of a data processing method of a vehicle networking system according to an embodiment of the present invention is shown, and the data processing method is applied to a vehicle-mounted communication terminal in the vehicle networking system, where the vehicle networking system further includes a vehicle networking server, and the method includes steps S100 to S400.

In the embodiment of the present invention, a Controller Area Network (CAN) signal definition needs to be first performed, and a total CAN Network signal of a vehicle is divided into a periodic signal and an event signal according to a service requirement of an internet of vehicles and an actual change situation of the signal. The full CAN network signal covers various vehicle condition signals of the vehicle. The periodic signal is a high-frequency and periodically-varying signal, and specifically, the periodic signal may be defined as a vehicle speed, a Global Positioning System (GPS) position, an accelerator pedal depth, a steering wheel angle, and the like; the event-type signal is a signal with a low variation frequency and an event trigger type, such as a door switch state, a lamp switch state, a battery remaining charge state of charge, and the like, and can be defined as an event-type signal.

The vehicle-mounted communication terminal is internally provided with the 4G communication module, CAN interact with a vehicle CAN bus and a vehicle networking server, and CAN deeply read the data of the vehicle CAN bus and a private protocol.

In the embodiment of the invention, the event type signal currently acquired by the vehicle-mounted communication terminal is defined as the second event type signal, and the event type signal acquired last time by the vehicle-mounted communication terminal is defined as the first event type signal.

S100, when a first preset timing task is achieved, obtaining periodic signals of the vehicle, and uploading data of the periodic signals to the Internet of vehicles server for storage.

In step S100, the first preset timing task is a timing task preset on the vehicle-mounted communication terminal, and when the first preset timing task reaches the first trigger condition, the vehicle-mounted communication terminal may be triggered to acquire a periodic signal corresponding to the vehicle. In practical application, the first preset time task can be set on a mobile phone application program which establishes communication connection with the vehicle-mounted communication terminal; and the first trigger condition may be a predetermined time, that is, when the current time reaches the predetermined time, the first preset timing task may be triggered.

In actual use, when a task is triggered at the first preset time, the vehicle-mounted communication terminal acquires a periodic signal corresponding to a vehicle through the CAN bus, and uploads data of the periodic signal to the Internet of vehicles server for storage. Optionally, the data of the periodic signal includes a third timestamp for acquiring the periodic signal, so that the car networking server stores the periodic signal in real time according to the third timestamp.

And S200, when the vehicle-mounted communication terminal acquires a first event type signal of a vehicle, uploading data of the first event type signal to the internet of vehicles server for storage.

In the step S200, the vehicle-mounted communication terminal acquires and records the data of the first event-type signal through the CAN bus for the first time, and uploads the data of the first event-type signal to the internet-of-vehicle server for storage.

In practical application, when the vehicle-mounted communication terminal logs on the internet-of-vehicles server and establishes connection for all event type signals for the first time, the vehicle-mounted communication terminal reads and records all event type signal data in the CAN bus, marks an initial state, and uploads the data to the internet-of-vehicles server.

Optionally, in the step S200, the data of the first event type signal includes a first timestamp for acquiring the first event type signal. When uploading the data of the first event type signal to the Internet of vehicles server, the first timestamp of the first event type signal is uploaded to the Internet of vehicles server at the same time, so that the Internet of vehicles server stores the first event type signal in real time according to the first timestamp.

Step S300, under the condition that a second event type signal of the vehicle is acquired by the vehicle-mounted communication terminal and is matched with the first event type signal acquired last time, ignoring the second event type signal.

In the step S300, after the vehicle-mounted communication terminal uploads the data of the first event-type signal to the internet-of-vehicles server for storage, the vehicle-mounted communication terminal continues to acquire a second event-type signal of the vehicle; when the vehicle-mounted communication terminal acquires a second event-type signal of the vehicle, if the matching degree of the second event-type signal and a first event-type signal acquired last time reaches a preset matching degree threshold value, the second event-type signal is matched with the first event-type signal acquired last time, that is, the current second event-type signal is considered to be the same as the first low-frequency event-type information acquired last time, so that the second event-type signal is ignored, that is, the second event-type signal is not uploaded to the internet-of-vehicles server, and therefore the situation that data the same as the first event-type signal is uploaded is avoided.

And step S400, when the vehicle-mounted communication terminal acquires a second event type signal and the second event type signal is not matched with the first event type signal acquired last time, uploading data of the second event type signal to the Internet of vehicles server for storage.

In the step S400, after the vehicle-mounted communication terminal uploads the data of the first event-type signal to the internet-of-vehicles server for storage, the vehicle-mounted communication terminal continues to acquire a second event-type signal of the vehicle; when the vehicle-mounted communication terminal acquires a second event-type signal of the vehicle, if the matching degree of the second event-type signal and a first event-type signal acquired last time does not reach a preset matching degree threshold value, it indicates that the second event-type signal is not matched with the first event-type signal acquired last time, that is, the current second event-type signal is different from the first low-frequency event-type information acquired last time, and therefore the second event-type signal needs to be uploaded to the internet-of-vehicles server, so that the internet-of-vehicles server can store the second event-type signal of the vehicle immediately.

Optionally, in the step S400, the data of the second event type signal includes a second timestamp for acquiring the second event type signal. That is, when the data of the second event type signal is uploaded to the internet of vehicles server, the second timestamp of the second event type signal is uploaded to the internet of vehicles server, so that the internet of vehicles server can store the second event type signal in real time according to the second timestamp.

In practical applications, in the steps S200 to S400, the first event-type signal and the second event-type signal are the same target event-type signal at two time points before and after, and the signal values of the first event-type signal and the second event-type signal may be different or the same; if the first event type signal and the second event type signal acquired last time are the same, the state of the target event type signal is not changed, and therefore the second event type signal is ignored, namely is not uploaded to the Internet of vehicles server; if the first event type signal and the second event type signal acquired last time are different, which indicates that the state of the target event type signal is changed, the changed data of the target event type signal needs to be uploaded to the internet of vehicles server, so that the data of the second event type signal is uploaded to the internet of vehicles server for storage.

Optionally, the vehicle-mounted communication terminal further includes a third preset timing task, and in steps S300 to S400, when the third preset timing is reached, the second event-type signal of the vehicle is acquired. In actual use, when a third preset timing task is triggered, the vehicle-mounted communication terminal acquires a current event type signal of a vehicle through the CAN bus, and uploads data of the current acquired event type signal to the Internet of vehicles server for storage when the current acquired low-frequency event type information is not matched with the last acquired event type signal, namely uploads data of the current acquired second event type signal to the Internet of vehicles server for storage when the current acquired second event type signal is not matched with the last acquired first event type signal.

Compared with the prior art, the vehicle networking data processing method has the following advantages:

Optionally, before step S100 in this embodiment of the present invention, the method further includes:

step S101, receiving a configuration file issued by the Internet of vehicles server, wherein the configuration file comprises the identification information of the periodic signal and the first preset timing task.

In the step S101, the identification information of the periodic signal and the corresponding first preset timing task are sent to the vehicle-mounted communication terminal through the vehicle networking server, so that when the vehicle-mounted communication terminal reaches the first preset timing task, the data of the periodic signal is acquired and uploaded to the vehicle networking server for storage.

In practical application, according to the difference between a service and an actual requirement, the periods/frequencies of data acquisition and data uploading corresponding to different periodic signals are different, so that the periods/frequencies of different data acquisition and data uploading need to be defined for different periodic signals, a configuration file is formed, the configuration file is issued to the vehicle-mounted communication terminal through the vehicle-mounted networking server, after the vehicle-mounted communication terminal receives the configuration file, the vehicle-mounted communication terminal acquires signal data of different periodic signals according to the corresponding periods and uploads the signal data to the vehicle-mounted networking server according to the requirements of the configuration file, and meanwhile, the vehicle-mounted networking server stores the actually received data in real time.

Further, in one embodiment, the data of the first event type signal includes a first timestamp for acquiring the first event type signal, and the data of the second event type signal includes a second timestamp for acquiring the second event type signal; the data of the periodic signal comprises a third timestamp for acquiring the periodic signal;

the method further comprises step S500:

step S500, when the vehicle-mounted communication terminal receives a first supplementary transmission instruction of the vehicle networking server, the vehicle-mounted communication terminal uploads data of periodic signals corresponding to timestamp information included in the first supplementary transmission instruction to the vehicle networking server, and the first supplementary transmission instruction includes timestamp information of periodic signals which are not successfully received.

In this embodiment, after the car networking server parses the received data of the periodic signal, the car networking server parses the data of the periodic signal, determines a difference between a current third timestamp included in the data of the current periodic signal and a previous third timestamp included in the data of the previous periodic signal, and determines whether the difference matches a time threshold in a first preset timing task, if the difference does not match the time threshold, it indicates that the data of the middle periodic signal is missing, and in order to ensure that the data of the periodic signal is complete, the car networking server issues a first supplementary transmission instruction to the car communication terminal to control the car communication terminal to upload the data of the periodic signal between the current third timestamp and the previous third timestamp to the car networking server. In practical application, the vehicle-mounted communication terminal buffers the latest data of a plurality of periodic signals.

In another embodiment, in an embodiment of the present invention, the data of the first event type signal includes a first packet sequence number, and the data of the second event type signal includes a second packet sequence number;

the method further comprises step S600:

step S600, when a second supplementary transmission instruction issued by the internet of vehicles server is received, uploading data of the event type signal corresponding to the data packet sequence number included in the second supplementary transmission instruction to the internet of vehicles server, where the second supplementary transmission instruction includes the data packet sequence number of the event type signal which is not successfully received.

In this embodiment, after the car networking server parses the received data of the second event type signal, the car networking server parses the data of the second event type signal, determines whether a second packet number included in the data of the current second event type signal and a first packet number included in the data of the last first event type signal are consecutive, and if not, indicates that the data of the second event type signal between the first packet number and the second packet number are missing. In practical application, the vehicle-mounted communication terminal buffers data of a plurality of second event type signals which are latest.

In the embodiment of the invention, before the data of the periodic signal is uploaded to the internet of vehicles server for storage, the data of the periodic signal is packaged; before uploading the data of the first event type signal to the Internet of vehicles server for storage, packaging the data of the first event type signal; and packaging the data of the second event type signal before uploading the data of the second event type signal to the Internet of vehicles server for storage.

The data packets obtained after the packaging processing are composed of start symbols, command identifiers, response identifiers, VINs, data unit encryption modes, data unit lengths, data units and check codes, and the visual structures of the data packets are shown in Table 1. Wherein, the command identifier is used for distinguishing the event type signal data packet from the periodic type signal data packet. The packet obtained by the above-described packetization processing may specifically adopt the architecture specified in GB/T32960-2016.3.

TABLE 1

Referring to fig. 2, a schematic flow chart of another data processing method for the internet of vehicles according to the embodiment of the present invention is shown, where the another data processing method for the internet of vehicles according to the embodiment of the present invention is applied to a server for the internet of vehicles in the internet of vehicles, and the internet of vehicles further includes a vehicle-mounted communication terminal, where the method includes steps S201 to S204.

And step S201, receiving and storing the data of the periodic signal uploaded by the vehicle-mounted communication terminal.

In the step S201, the car networking server stores the data of the periodic signal uploaded by the vehicle-mounted communication terminal in real time according to actual reception, so that other devices can query the periodic signal of the vehicle in real time through the car networking server, and the effect of periodic signal interaction is achieved.

And step S202, receiving and storing the data of the first event type signal uploaded by the vehicle-mounted communication terminal.

In the step S202, the car networking server stores the data of the first event type signal uploaded by the vehicle-mounted communication terminal in real time according to actual reception, so that other devices can query the first event type signal of the vehicle in real time through the car networking server, and an effect of interaction of the first event type signal is achieved.

And step S203, receiving and storing data of a second event type signal uploaded by the vehicle-mounted communication terminal, wherein the second event type signal is not matched with the first event type signal received last time.

In step S203, when the vehicle networking server actually receives the data of the second event type signal that is uploaded by the vehicle-mounted communication terminal and is not matched with the last received first event type signal, the data is stored in real time, so that other devices can query the second event type signal of the vehicle in real time through the vehicle networking server, and an effect of second event type signal interaction is achieved.

Step S204, when receiving the query instruction sent by the query terminal, adding the periodic signal or the first event signal or the second event signal corresponding to the query instruction into the response aiming at the query instruction.

In step S204, when the query terminal is to query a target signal of a vehicle, it sends a query instruction to the internet of vehicles server, where the query instruction includes identification information of the target signal, and the target signal may be a periodic signal or a first event type signal or a second event type signal; when the internet of vehicles server receives the query instruction, the corresponding periodic signal or the first event signal or the second event signal is added to the response aiming at the query instruction according to the identification information of the target signal, and then the target signal can be sent to the query terminal.

Compared with the prior art, the control method of the vehicle lamp has the following advantages:

In a preferred embodiment, the data processing method for the internet of vehicles provided by the present invention is applied to a server of the internet of vehicles in the internet of vehicles, and the internet of vehicles further includes a vehicle-mounted communication terminal, wherein the method includes steps S301 to S307.

Step S301, a configuration file is issued to the vehicle-mounted communication terminal, wherein the configuration file comprises identification information of periodic signals and a first preset timing task, and the periodic signals are acquired when the vehicle-mounted communication terminal is controlled to reach the first preset timing task through the configuration file.

For the above step S301, in practical application, according to the difference between the service and the actual requirement, the periods/frequencies of data acquisition and data uploading corresponding to different periodic signals are different, so that it is necessary to define the periods/frequencies of data acquisition and data uploading for different periodic signals, form a configuration file, and then send the configuration file to the vehicle-mounted communication terminal through the vehicle-mounted communication server, after receiving the configuration file, the vehicle-mounted communication terminal acquires signal data of different periodic signals according to the corresponding periods and uploads the signal data to the vehicle-mounted communication server according to the requirements of the configuration file, and at the same time, the vehicle-mounted communication server stores the actually received data in real time.

Step S302, receiving data of the periodic signals uploaded by the vehicle-mounted communication terminal, and storing the periodic signals according to a third timestamp in the data of the periodic signals, wherein the third timestamp is a timestamp for acquiring the periodic signals.

In the step S302, when uploading the data of the periodic signal, the vehicle-mounted communication terminal uploads the third timestamp of the acquired periodic signal together, so that the vehicle networking server stores the periodic signal in real time according to the third timestamp.

Step S303, if the time difference between the current third timestamp and the last third timestamp is not matched with the time threshold value in the first preset time task, a first supplementary transmission instruction is issued to the vehicle-mounted communication terminal so as to control the vehicle-mounted communication terminal to upload the data of the periodic signals between the current third timestamp and the last third timestamp to the vehicle networking server.

In step S304, since the vehicle-mounted communication terminal acquires the periodic signal of the vehicle according to the first preset time task and uploads the data of the periodic signal to the internet of vehicles server, theoretically, the time difference between the current third timestamp received by the internet of vehicles server and the last third timestamp should match the time threshold in the first preset time task. The current third timestamp is a third timestamp in the data of the currently received periodic signal, and the last third timestamp is a third timestamp in the data of the last received periodic signal.

In the step S304, if the time difference between the current third timestamp and the last third timestamp should not match the time threshold in the first preset task, it indicates that there is data loss of the periodic signal between the current third timestamp and the last third timestamp. In order to ensure the integrity of the data of the periodic signal, the vehicle networking server issues a first supplementary transmission instruction to the vehicle communication terminal to control the vehicle communication terminal to upload the data of the periodic signal between the current third timestamp and the last third timestamp to the vehicle networking server again. In practical application, the vehicle-mounted communication terminal buffers the latest data of a plurality of periodic signals.

Optionally, when the vehicle networking server receives data of the periodic signal between the current third timestamp and the last third timestamp, the periodic signal between the current third timestamp and the last third timestamp is stored according to the third timestamp in the data.

Step S304, receiving data of a first event type signal uploaded by the vehicle-mounted communication terminal, and storing the first event type signal according to a first timestamp in the data of the first event type signal, where the first timestamp is a timestamp for acquiring the first event type signal.

In the step S304, when the vehicle-mounted communication terminal uploads the data of the first event-type signal, the vehicle-mounted communication terminal uploads the first timestamp of the acquired first event-type signal together, so that the vehicle networking server stores the periodic signal in real time according to the first timestamp.

Step S305, receiving data of a second event type signal uploaded by the vehicle-mounted communication terminal, and storing the second event type signal according to a second timestamp in the data of the second event type signal, where the second event type signal is not matched with a last received first event type signal, and the second timestamp is a timestamp for acquiring the second event type signal.

In the step S305, when uploading data of a second event-type signal that is not matched with the last acquired first event-type signal, the vehicle-mounted communication terminal uploads a second timestamp of the acquired second event-type signal together, so that the vehicle networking server stores the periodic signal in real time according to the second timestamp.

Step S306, if the currently received second packet sequence number is not consecutive to the last received first packet sequence number, issuing a second retransmission instruction to the vehicle-mounted communication terminal to control the vehicle-mounted communication terminal to upload data of a second event type signal that has not been successfully received to the vehicle-mounted networking server, where the second event type signal that has not been successfully received is a second event type signal corresponding to a packet sequence number between the currently received second packet sequence number and the last received first packet sequence number, the currently received second packet sequence number is a packet sequence number in the data of the currently received second event type signal, and the last received first packet sequence number is a packet sequence number in the data of the last received first event type signal.

When the vehicle-mounted communication terminal is used for data of the first event type signal, a first data packet serial number is marked to the data of the first event type signal; and when the vehicle-mounted communication terminal is used for the data of the second event type signal, a second data packet sequence number is marked to the data of the second event type signal, and the second data packet sequence number is continuous with the first data packet sequence number. If the uploaded data of the first event type signal and the uploaded data of the second event type signal are not lost, the sequence number of the second data packet currently received by the internet of vehicles server is continuous with the sequence number of the last first data packet received by the internet of vehicles server. If the second data packet sequence number is not continuous with the first data packet sequence number, the fact that the second event type signal data between the first data packet sequence number received last time and the currently received second data packet sequence number is missing is indicated, and in order to guarantee the integrity of the second event type signal data, the vehicle networking server sends a second supplementary transmission instruction to the vehicle communication terminal so as to control the vehicle communication terminal to upload the second low-frequency event type signal data between the first data packet sequence number received last time and the currently received second data packet sequence number to the vehicle networking server. In practical applications, the vehicle-mounted communication terminal may buffer data of the latest plurality of second event-type signals.

Optionally, when the vehicle networking server receives the data of the second event type signal which is not successfully received, the second event type signal which is not successfully received is stored according to the time stamp in the data of the second event type signal which is not successfully received.

Step S307, when receiving the query instruction sent by the query terminal, adding the periodic signal or the first event signal or the second event signal corresponding to the query instruction to the response to the query instruction.

The above step S307 can refer to the description of step S204, and is not described herein again.

Optionally, the method for processing data in the internet of vehicles according to the embodiment of the present invention further includes step S308:

step S308, after receiving the data of the previous second event type signal and before receiving the data of the next second event type signal, if the second preset timing task is reached, storing the previous second event type signal according to the current time.

In step S308, since the car networking server needs to store the second event type signals at different times, and after receiving the data of the previous second event type signal and before receiving the data of the next second event type signal, it indicates that the target event type signal is not changed, and the state matching the first event type signal is maintained, so that the second preset timing task can be achieved, and the previous second event type signal is stored according to the current time.

Optionally, in the method for processing data in the internet of vehicles according to the embodiment of the present invention, after step S308, step S309 is further included:

step S309, after receiving the data of the previous second event type signal, if the data of the next second event type signal has not been received after a preset number of second preset timing tasks have passed, stopping the operation of storing the previous second event type signal according to the current time.

In step S309, if the data of the next second event type signal is not received after the predetermined number of second predetermined timing tasks have elapsed after the data of the previous second event type signal is received, it is determined that the vehicle is in the sleep state, and the signal does not change in a short time, so that the operation of storing the previous second event type signal at the current time may be stopped.

the vehicle networking server only needs to receive the periodic signal sent by the vehicle communication terminal, the first event type signal and the second event type signal which is not matched with the first event type signal, so that a large number of second event type signals matched with the first event type signal on the vehicle communication terminal side are omitted, and the data communication flow between the vehicle communication terminal and the vehicle networking server can be greatly reduced on the premise that the stored data content of the vehicle networking server is not changed and the effective data is not reduced; meanwhile, whether a periodic signal is lost is determined by judging whether the time difference between the current third timestamp and the last third timestamp is matched with a time threshold value in the first preset timing task, and a first supplementary transmission instruction is issued to the vehicle-mounted communication terminal when the periodic signal is lost so as to control the vehicle-mounted communication terminal to upload data of the periodic signal between the current third timestamp and the last third timestamp to the vehicle networking server; and whether a second event type signal is lost is continuously determined through the currently received second data packet sequence number and the last received first data packet sequence number, and a second supplementary transmission instruction is issued to the vehicle-mounted communication terminal when the second event type signal is determined to be lost, so that the vehicle-mounted communication terminal is controlled to upload the data of the second event type signal which is not successfully received to the vehicle networking server. Therefore, the problems that communication congestion is caused easily, communication cost is overhigh and supplementary transmission cannot be carried out after signals are lost due to the fact that massive data interaction needs to be carried out between vehicles and a server in the existing vehicle networking are solved.
