Description

Vehicle communication method, device, computer readable medium and electronic equipment

Technical Field

The application relates to the technical field of internet of vehicles, in particular to a vehicle communication method, a device, a computer readable medium and electronic equipment.

Background

Because the communication bodies in the internet of vehicles may use different protocols to encapsulate information to realize communication, in the internet of vehicles system, when the vehicles communicate with any body (such as a cloud platform, a vehicle, a road communication facility and a mobile terminal of a user), the information of the other party can be obtained by analyzing a protocol packet, which means that if multiple protocols exist in the internet of vehicles, the vehicles in the internet of vehicles also need to have multiple protocol analysis functions.

However, the more communication bodies adopting different protocols to encapsulate information in the internet of vehicles, the more protocol analysis functions the vehicles need to have, the larger the storage and calculation resource occupancy rate of the vehicles is, and further larger communication delay and more lost information may be brought, which will seriously affect the information communication quality of the internet of vehicles.

In an application scenario of the present application, the network device 104 may acquire a protocol structure corresponding to an existing communication protocol in the vehicle network, and determine a target protocol structure with a deviation degree between the protocol structures corresponding to the existing communication protocol being less than or equal to a preset threshold.

The implementation details of the technical solutions of the embodiments of the present application are described in detail below:

fig. 2 shows a flowchart of a vehicle communication method according to an embodiment of the present application, which may be performed by a network device, which may be the network device 104 shown in fig. 1, referring to fig. 2, the vehicle communication method includes:

step S210, acquiring protocol structures corresponding to at least two existing communication protocols in the Internet of vehicles, wherein the protocol structures comprise a protocol head length and a protocol tail length;

step S220, determining a target protocol structure with the deviation degree smaller than or equal to a preset threshold value between the protocol structures corresponding to at least two communication protocols according to the protocol structures corresponding to at least two communication protocols, wherein the target protocol structure is used for generating a target communication protocol for internet-of-things communication.

These steps are described in detail below.

In step S210, a protocol structure corresponding to at least two communication protocols existing in the internet of vehicles is obtained, where the protocol structure includes a protocol header length and a protocol trailer length.

Communication between the vehicle and the cloud platform, communication between the vehicle and the vehicle, communication between the vehicle and the road, communication between the vehicle and people and communication between in-vehicle devices can be realized in the Internet of vehicles. And the communication protocol refers to rules and conventions followed by communication or services performed between communication entities in the internet of vehicles, where different communication entities may use different communication protocols to encapsulate information to perform the communication or services, for example, communication protocol 1 is used to perform communication between vehicle 1 and vehicle 2, communication protocol 2 is used to perform communication between vehicle 1 and vehicle 3, and communication protocol 3 is used to perform communication between vehicle 1 and road communication facility 1, where communication protocol 1, communication protocol 2 and communication protocol 3 are represented herein as different communication protocols.

Thus, at least two communication protocols existing in the internet of vehicles can be acquired by the execution subject, wherein at least two means two or more. It should be understood that each communication protocol has a corresponding protocol structure, which is a structure formed including a protocol header length and a protocol trailer length.

In an embodiment of the present application, the acquiring manner may be that the executing body actively acquires protocol structures corresponding to at least two communication protocols existing in the internet of vehicles, or the executing body reports the communication protocol used by the executing body to the executing body, so that the executing body can acquire protocol structures corresponding to at least two communication protocols existing in the internet of vehicles.

Specifically, after the executing body acquires the protocol structures corresponding to the at least two communication protocols, the executing body may determine a target protocol structure that satisfies a condition, where the condition may be that a degree of deviation between the protocol structures corresponding to the at least two communication protocols is less than or equal to a preset threshold. The preset threshold may be a value summarized empirically in advance.

The deviation degree, as the name implies, refers to the deviation degree between protocol structures, and the meaning is exemplified, and if a communication protocol used by a certain vehicle in the internet of vehicles is not its original communication protocol but a new communication protocol, the following two cases exist: a) The length of the protocol structure of the new communication protocol is smaller than that of the original communication protocol; or b) the length of the protocol structure of the new communication protocol is greater than the length of the protocol structure of the original communication protocol. It can be seen that, in either case a) or b), there is always a deviation between the protocol structure of the new communication protocol and the protocol structure of the original communication protocol, which deviation is the degree of deviation.

It should be noted that, the target protocol structure may be used to generate a target communication protocol for internet of vehicles communication, in other words, after the target protocol structure is determined, the target protocol structure may be used to generate the target communication protocol for internet of vehicles communication, and then vehicles in the internet of vehicles may use the target communication protocol to communicate when communicating, that is, the technical scheme provided by the embodiment of the application does not need the vehicles themselves to have at least two protocol analysis functions, the vehicles may communicate through the target communication protocol, and only needs to analyze the information encapsulated by the received target communication protocol, thereby saving the calculation storage resources of the vehicles, reducing the delay of vehicle communication, and further improving the information communication quality of the internet of vehicles.

In one embodiment of the present application, since the protocol structure includes a protocol header length and a protocol tail length, as shown in fig. 3, step S220 may specifically include steps S2201-S2203, which are described in detail below:

step S2201, according to the protocol structures corresponding to the at least two communication protocols, calculates a protocol length with a deviation degree between the protocol structures corresponding to the at least two communication protocols being less than or equal to a preset threshold.

In one embodiment of the present application, the degree of deviation Q may be calculated by the following formula:

wherein n is the number of communication protocols existing in the Internet of vehicles, H _i For the length of the protocol head of the protocol structure corresponding to the ith communication protocol existing in the Internet of vehicles, E _i And L is used for representing the protocol length for the protocol tail length of a protocol structure corresponding to the i-th communication protocol existing in the Internet of vehicles.

From the above formula, if a certain protocol length L and the sum of the protocol header length and the protocol tail length corresponding to the protocol structure corresponding to the existing communication protocol are known, the degree of deviation between the two can be expressed according to the absolute value of the difference between the two.

Therefore, in this step, in particular, conversely, a protocol length, in which the degree of deviation between the protocol structures corresponding to the at least two communication protocols is less than or equal to the preset threshold, may also be calculated according to the protocol structures corresponding to the at least two communication protocols.

In one embodiment of the present application, the value of L when the deviation degree takes the minimum value may also be calculated according to the above formula, and the value of L at this time is taken as the protocol length.

Step S2202, calculating a new protocol header length and a new protocol tail length according to the protocol length and the protocol structures corresponding to at least two communication protocols.

After the protocol length satisfying the condition is obtained in step S2201, a new protocol header length and a new protocol trailer length may be further calculated based on the protocol length and the protocol structures corresponding to at least two communication protocols.

Specifically, the new protocol header length and the new protocol tail length may be calculated according to the protocol header length and the protocol tail length of the protocol structures corresponding to the at least two communication protocols, and the protocol length obtained in step S2201. In one embodiment, the protocol length may be divided based on an average value of a sum of protocol header lengths of protocol structures corresponding to at least two communication protocols and an average value of a sum of protocol tail lengths of protocol structures corresponding to at least two communication protocols, and a new protocol header length and a new protocol tail length are calculated.

Step S2203, determining the target protocol structure according to the new protocol header length and the new protocol tail length.

Specifically, after the new protocol header length and the new protocol tail length are calculated, the new protocol header length can be used as the protocol header length of the target protocol structure, and the new protocol tail length can be used as the protocol tail length of the target protocol structure, so that the target protocol structure is determined.

In one embodiment of the present application, as shown in fig. 4, step S2202 specifically includes steps S22021-S22023:

step S22021, calculating the sum of the length of the protocol head and the length of the protocol tail of the protocol structure corresponding to at least two communication protocols according to the protocol structure corresponding to at least two communication protocols to obtain the length sum value;

step S22022, calculating a first ratio between the sum of the lengths of the protocol heads and the length and the value of the protocol structures corresponding to at least two communication protocols, and a second ratio between the sum of the lengths of the protocol tails and the length and the value of the protocol structures corresponding to at least two communication protocols;

step S22023, dividing the protocol length according to the first ratio and the second ratio to obtain a new protocol header length and a new protocol tail length.

These steps are described in detail below.

In step S22021, according to the protocol structures corresponding to the at least two communication protocols, the sum of the protocol header length and the protocol trailer length of the protocol structures corresponding to the at least two communication protocols is calculated, so as to obtain the length sum value.

Specifically, the length of the protocol header and the length of the protocol tail of the protocol structure corresponding to at least two communication protocols are summed to obtain a length sum value.

For example, if there are n kinds of communication protocols, respectively denoted as S1, S2, and S3 … Sn, and the protocol header lengths of the protocol structures corresponding to the various communication protocols are respectively denoted as H1, H2, and H3 … Hn, and the protocol tail lengths of the protocol structures corresponding to the various communication protocols are respectively denoted as E1, E2, and E3 … En, the sum of the lengths s=h1+e1+h2+e2+h3+e3 … … hn+en can be obtained.

Step S22022, calculating a first ratio between the sum of the lengths of the protocol headers and the length and the value of the protocol structures corresponding to the at least two communication protocols, and a second ratio between the sum of the lengths of the protocol tails and the length and the value of the protocol structures corresponding to the at least two communication protocols.

After the length and the value are obtained, a first ratio between the sum of the lengths of the protocol heads of the protocol structures corresponding to at least two communication protocols and the length and the value and a second ratio between the sum of the lengths of the protocol tails of the protocol structures corresponding to at least two communication protocols and the length and the value are further calculated.

Continuing with the above example, a first ratio q1= (h1+h2+h3+ … +hn)/S and a second ratio q2= (e1+e2+e3+ … +en)/S may be calculated.

After the first ratio and the second ratio are calculated, the protocol length can be divided by using the first ratio and the second ratio, the part corresponding to the first ratio is used as a new protocol head length, and the part corresponding to the second ratio is used as a new protocol tail length.

Based on the technical scheme provided by the embodiment, the new protocol head length and the new protocol tail length are calculated by using the first ratio of the sum of the lengths of the existing protocol heads to the sum of the lengths of the values and the second ratio of the sum of the lengths of the existing protocol tails to the sum of the lengths of the values, so that the target protocol structure determined by the new protocol head length and the new protocol tail length corresponds to the protocol structure of the existing communication protocol, and the function of the existing communication protocol can be reserved to the greatest extent by the target protocol structure.

In an embodiment of the present application, after determining the target protocol structure, the executing body may further generate a target communication protocol corresponding to an existing communication protocol according to the target protocol structure, where in this embodiment, as shown in fig. 5, the vehicle communication method further includes:

Step S510, determining the target protocol content corresponding to each communication protocol based on the target protocol structure and the protocol content corresponding to each communication protocol in at least two communication protocols;

step S520, generating a target communication protocol corresponding to each communication protocol according to the target protocol structure and the target protocol content corresponding to each communication protocol.

In step S510, after the execution body determines the target protocol structure, all vehicles in the internet of vehicles can communicate by using the target protocol structure, and it is understood that, in order to implement internet of vehicles communication, when the communication is performed by using the target protocol structure, the protocol content needs to be encapsulated by using the target protocol structure, so as to obtain a complete communication protocol.

In this embodiment, the target protocol structure and the existing protocol content determine the target protocol content, so that the target protocol content is determined on the basis of fully combining the characteristics of the existing protocol content of the vehicle, the replacement of the communication protocol is avoided, and the data loss caused by the replacement of the communication protocol can be further reduced to the greatest extent.

In step S520, a target communication protocol corresponding to each communication protocol is generated based on the target protocol structure and the target protocol content corresponding to each communication protocol.

Specifically, after the target protocol structure and the target protocol content corresponding to each communication protocol are determined, the target communication protocol corresponding to each communication protocol can be generated directly according to the target protocol structure and the target protocol content corresponding to each communication protocol.

Since the protocol structure of each communication protocol is unlikely to be identical to the target protocol structure, when determining the target protocol content corresponding to each communication protocol based on the target protocol structure and the protocol content corresponding to each communication protocol, different processing modes can be selected according to various conditions existing between the protocol structure of each communication protocol and the target protocol structure.

In one embodiment of the present application, as shown in fig. 6, step S510 specifically includes:

step S610, a first type of communication protocol with a protocol header length greater than that of the target protocol structure and a protocol tail length greater than that of the target protocol structure is obtained from at least two communication protocols;

Step S620, according to the order of importance from high to low, acquiring first data with the same length as the protocol header of the target protocol structure from the protocol header data of the first type of communication protocol, and acquiring second data with the same length as the protocol tail of the target protocol structure from the protocol tail data of the first type of communication protocol;

step S630, the first data is used as the protocol header data of the target protocol content, and the second data is used as the protocol trailer data of the target protocol content, so as to generate the target protocol content.

In step S610, a first type of communication protocol having a protocol header length greater than a protocol header length of the target protocol structure and a protocol trailer length greater than a protocol trailer length of the target protocol structure is acquired from at least two communication protocols.

Because the protocol structures of at least two existing communication protocols may be different from the target protocol structure, the protocol structures of at least two communication protocols may be compared with the target protocol structure, and then the determination mode of the target protocol content may be selected according to the comparison result.

In this embodiment, a first type of communication protocol may be obtained from at least two types of communication protocols, and a comparison schematic diagram of a protocol structure of the first type of communication protocol and a target protocol structure may be referred to as fig. 12, where a protocol header length of the first type of communication protocol is greater than a protocol header length of the target protocol structure, and a protocol trailer length of the first type of communication protocol is greater than a protocol trailer length of the target protocol structure.

In step S620, first data with the same length as the protocol header of the target protocol structure is obtained from the protocol header data of the first type of communication protocol in order of high importance from low importance, and second data with the same length as the protocol trailer of the target protocol structure is obtained from the protocol trailer data of the first type of communication protocol.

For the first type of communication protocol, since the length of the protocol header and the length of the protocol tail are respectively greater than the length of the protocol header and the length of the protocol tail of the target protocol structure, it is impossible to load all the protocol header data and the protocol tail data of the first type of communication protocol into the protocol header and the protocol tail of the target protocol structure respectively, in one embodiment, the protocol contents of the first type of communication protocol can be ordered from high to low in importance, it is understood that the importance of the protocol contents is preset, for example, the importance of the information representing the license plate of the vehicle in the protocol contents is self-evident, otherwise, the information transmitted by the vehicle is difficult to correspond to the vehicle transmitting the information.

After the importance of the protocol header data of the first type of communication protocol is sequenced, the first data with the same length as the protocol header of the target protocol structure can be obtained from the protocol header data, and likewise, after the importance of the protocol trailer data of the first type of communication protocol is sequenced, the second data with the same length as the protocol trailer of the target protocol structure can be obtained from the protocol header and the protocol trailer.

Because the first data includes the data with the same length as the protocol header of the target protocol structure, and the second data includes the data with the same length as the protocol trailer of the target protocol structure, the first data can be completely loaded into the protocol header of the target protocol structure, and the second data can be completely loaded into the protocol trailer of the target protocol structure, that is, the first data is used as the protocol header data of the target protocol content, and the second data is used as the protocol trailer data of the target protocol content, so that the target protocol content is generated according to the protocol header data of the target protocol content and the protocol trailer data of the target protocol content.

The first data may be sequentially loaded into the protocol header of the target protocol structure according to importance, or the first data may be randomly loaded into the protocol header of the target protocol structure, and similarly, the second data may be sequentially loaded into the protocol tail of the target protocol structure according to importance, or the second data may be randomly loaded into the protocol header of the target protocol structure.

In one embodiment of the present application, as shown in fig. 7, step S510 specifically includes:

step S710, a second type of communication protocol with a protocol header length smaller than or equal to the protocol header length of the target protocol structure and a protocol tail length smaller than or equal to the protocol tail length of the target protocol structure is obtained from at least two communication protocols;

step S720, the protocol header data of the second type communication protocol is used as the protocol header data of the target protocol content, and the protocol tail data of the second type communication protocol is used as the protocol tail data of the target protocol content, so as to generate the target protocol content.

These steps are explained in detail below:

in step S710, a second type of communication protocol having a protocol header length less than or equal to a protocol header length of the target protocol structure and a protocol trailer length less than or equal to a protocol trailer length of the target protocol structure is acquired from at least two communication protocols.

In this embodiment, the second type of communication protocol may be obtained from at least two types of communication protocols, and a comparison diagram of a protocol structure of the second type of communication protocol and a target protocol structure may be seen in fig. 13A-13D, which includes four cases in total, as shown in fig. 13A, where the first case is: the protocol head length and the protocol tail length of the second type of communication protocol are respectively smaller than the protocol head length and the protocol tail length of the target protocol structure; as shown in fig. 13B, the second case is: the protocol head length and the protocol tail length of the second type of communication protocol are respectively equal to the protocol head length and the protocol tail length of the target protocol structure; as shown in fig. 13C, the third case is: the protocol head length of the second type of communication protocol is smaller than the protocol head length of the target protocol structure, but the protocol tail length of the second type of communication protocol is equal to the protocol tail length of the target protocol structure; as shown in fig. 13D, the fourth case is: the second type of communication protocol has a protocol header length equal to the protocol header length of the target protocol structure, but a protocol trailer length less than the protocol trailer length of the target protocol structure.

In step S720, the protocol header data of the second type communication protocol is used as the protocol header data of the target protocol content, and the protocol trailer data of the second type communication protocol is used as the protocol trailer data of the target protocol content, so as to generate the target protocol content.

For the second type of communication protocol, the protocol header length and the protocol trailer length are respectively smaller than the protocol header length and the protocol trailer length of the target protocol structure, or are respectively equal to the protocol header length and the protocol trailer length of the target protocol structure, or are respectively smaller than the protocol header length of the target protocol structure, the protocol trailer length is equal to the protocol trailer length of the target protocol structure, or are respectively equal to the protocol header length of the target protocol structure, and are smaller than the protocol trailer length of the target protocol structure, however, in either case, the protocol header data of the second type of communication protocol can be directly used as the protocol header data of the target protocol content, and the protocol trailer data of the second type of communication protocol can be used as the protocol trailer data of the target protocol content.

In addition, for the case that the protocol header length of the second type of communication protocol is smaller than the protocol header length of the target protocol structure, the rest of the protocol header of the target protocol structure may be further emptied or taken as a default value, where the default value may be determined according to the specific situation, where the rest of the protocol header of the target protocol structure refers to a portion lacking loadable protocol header data; alternatively, in the case that the protocol tail length of the second type of communication protocol is smaller than the protocol head length of the target protocol structure, the rest of the protocol tail of the target protocol structure may be emptied or taken as a default value.

In one embodiment of the present application, as shown in fig. 8, step S510 specifically includes steps S810 to S830, which are described in detail below:

in step S810, a third type of communication protocol having a protocol header length less than or equal to the protocol header length of the target protocol structure but a protocol trailer length greater than the protocol trailer length of the target protocol structure is acquired from the at least two communication protocols.

In this embodiment, a third type of communication protocol may be obtained from at least two types of communication protocols, and a comparison schematic diagram of a protocol structure of the third type of communication protocol and a target protocol structure may be seen in fig. 14A-14B, which includes two cases, as shown in fig. 14A, where the first case is: the protocol head length of the third type of communication protocol is smaller than the protocol head length of the target protocol structure, but the protocol tail length of the third type of communication protocol is larger than the protocol tail length of the target protocol structure; as shown in fig. 14B, the second case is: the protocol header length of the third type of communication protocol is equal to the protocol header length of the target protocol structure, but the protocol trailer length of the third type of communication protocol is greater than the protocol trailer length of the target protocol structure.

Step S820, obtaining third data with the same protocol tail length as the target protocol structure from the protocol tail data of the third type of communication protocol according to the order of importance from high to low.

For the third type of communication protocol, since its protocol tail length is greater than the protocol tail length of the target protocol structure, it is impossible to load all of the protocol tail data of the third type of communication protocol into the protocol tail of the target protocol structure, and in one embodiment, the protocol tail data of the third type of communication protocol may be ordered from high to low in importance.

After ordering the importance of the protocol tail data of the third type of communication protocol, third data with the same protocol tail length as the target protocol structure can be obtained from the protocol tail data.

In step S830, the third data is used as the protocol tail data of the target protocol content, and the protocol header data of the third type of communication protocol is used as the protocol header data of the target protocol content, so as to generate the target protocol content.

Because the length of the protocol header of the third type of communication protocol is smaller than or equal to the length of the protocol header of the target protocol structure, the protocol header data of the third type of communication protocol can be completely loaded into the protocol header of the target protocol structure, that is, the protocol header data of the third type of communication protocol is used as the protocol header data of the target protocol content, and meanwhile, the third data obtained in the step S820 is used as the protocol tail data of the target protocol content, so that the target protocol content is generated according to the protocol header data of the target protocol content and the protocol tail data of the target protocol content.

In addition, for the case that the length of the protocol header of the third type of communication protocol is smaller than the length of the protocol header of the target protocol structure, the rest of the protocol header of the target protocol structure may be emptied or taken as a default value.

In one embodiment of the present application, as shown in fig. 9, step S510 specifically includes steps S910 to S920, which are now described in detail as follows:

step S910, a fourth type of communication protocol having a protocol header length greater than the protocol header length of the target protocol structure but a protocol trailer length less than or equal to the protocol trailer length of the target protocol structure is acquired from the at least two communication protocols.

In this embodiment, a fourth type of communication protocol can be obtained from at least two types of communication protocols, and a comparison diagram of a protocol structure of the fourth type of communication protocol and a target protocol structure can be seen in fig. 15A-15B, which includes two cases in total, as shown in fig. 15A, where the first case is: the protocol head length of the fourth type of communication protocol is larger than the protocol head length of the target protocol structure, but the protocol tail length of the fourth type of communication protocol is smaller than the protocol tail length of the target protocol structure; as shown in fig. 15B, the second case is: the protocol header length of the fourth type of communication protocol is greater than the protocol header length of the target protocol structure, but the protocol trailer length of the fourth type of communication protocol is equal to the protocol trailer length of the target protocol structure.

In step S920, fourth data with the same length as the protocol header of the target protocol structure is acquired from the protocol header data of the fourth type of communication protocol in order of importance from high to low.

For the fourth type of communication protocol, since its protocol header length is greater than the protocol header length of the target protocol structure, it is impossible to load all of the protocol header data of the fourth type of communication protocol into the protocol header of the target protocol structure, and in one embodiment, the protocol header data of the fourth type of communication protocol may be ordered from high to low in importance.

After ordering the importance of the protocol header data of the fourth type of communication protocol, fourth data with the same length as the protocol header of the target protocol structure can be obtained from the protocol header data.

In step S930, the fourth data is used as the protocol header data of the target protocol content, and the protocol tail data of the fourth type of communication protocol is used as the protocol tail data of the target protocol content, so as to generate the target protocol content.

Because the length of the protocol tail of the fourth type of communication protocol is smaller than or equal to the length of the protocol tail of the target protocol structure, the protocol tail data of the fourth type of communication protocol can be completely loaded into the protocol tail of the target protocol structure, that is, the protocol tail data of the fourth type of communication protocol is used as the protocol tail data of the target protocol content, and meanwhile, the fourth data obtained in the step S920 is used as the protocol head data of the target protocol content, so that the target protocol content is generated according to the protocol head data of the target protocol content and the protocol tail data of the target protocol content.

In addition, for the case that the length of the protocol header of the fourth type of communication protocol is smaller than the length of the protocol tail of the target protocol structure, the rest part of the protocol tail of the target protocol structure can be emptied or taken as a default value.

In the following, a frame protocol used by a vehicle to report its own information to other vehicles in the driving of the internet of vehicles safety assistance is illustrated, and tables 1-1, 1-2 and 1-3 respectively show three communication protocols used by the vehicle in reporting to other vehicles, and in the technical scheme of the embodiment of the present application, the determined target protocol structure is the same as the communication protocol structure shown in table 1-3, so that the target communication protocols corresponding to the three communication protocols can be obtained according to the technical scheme of the embodiment of the present application, as shown in table 2-1, table 2-2 and table 2-3.

As can be seen from table 1-1, the protocol header length of the communication protocol of table 1-1 is equal to the protocol header length of the target protocol structure, but the protocol tail length is greater than the protocol tail length of the target protocol structure, so that the communication protocol of table 1-1 belongs to the third type of communication protocol, and therefore, the protocol header data of the communication protocol of table 1-1 can be regarded as the protocol header data of the target protocol content, and the protocol tail data of the communication protocol of table 1-1 can be sorted in importance, and the protocol tail data with the first three sorted importance can be obtained, namely, whether traffic light data, traffic light type (failure) is 0, red: 1, yellow: 2, green: 3) and traffic light distance are respectively, and the obtained protocol tail data with the first three bits is regarded as the protocol tail data of the target protocol content, so that the target communication protocol corresponding to table 1-1 as shown in table 2-1 can be obtained.

As can be seen from table 1-2, the protocol header length of the communication protocol of table 1-2 is smaller than the protocol header length of the target protocol structure, and the protocol trailer length is smaller than the protocol trailer length of the target protocol structure, so that the communication protocol of table 1-1 belongs to the second type of communication protocol, so that the protocol header data of the communication protocol of table 1-2 can be used as the protocol header data of the target protocol content, the protocol trailer data of the communication protocol of table 1-2 can be used as the protocol trailer data of the target protocol content, and the rest of the protocol header of the target protocol structure and the rest of the protocol trailer of the target protocol structure are emptied, so that the target communication protocol corresponding to table 1-2 as shown in table 2-2 can be obtained.

As can be seen from tables 1 to 3, the protocol header length of the communication protocol of tables 1 to 3 is equal to the protocol header length of the target protocol structure, and the protocol trailer length is equal to the protocol trailer length of the target protocol structure, and therefore, the communication protocol of tables 1 to 3 belongs to the second type of communication protocol, so that the protocol header data of the communication protocol of tables 1 to 3 can be used as the protocol header data of the target protocol content, and the protocol trailer data of the communication protocol of tables 1 to 3 can be used as the protocol trailer data of the target protocol content, so that the target communication protocol corresponding to tables 1 to 3 as shown in tables 2 to 3 can be obtained.

In one embodiment of the present application, since at least two communication protocols exist in the internet of vehicles, as shown in fig. 10, step S210 may specifically include steps S2101 to S2102, which will be described in detail below:

step S2101, classifying the at least two communication protocols according to the protocol structures corresponding to the at least two communication protocols, to obtain at least one type of communication protocol.

Specifically, each vehicle in the internet of vehicles can report the communication protocol used by each vehicle to the execution main body, and after receiving the reported communication protocol, the execution main body can classify the communication protocols into one type according to the protocol structure corresponding to the communication protocol, so as to obtain at least one type of communication protocol, wherein the protocol structure is identical, which means that the length of the protocol head and the length of the protocol tail are identical. It should be noted that at least one type refers to one type or more types, and multiple types refer to two types or more than two types.

Step S2102, obtaining a protocol structure corresponding to each type of communication protocol in at least one type of communication protocol.

Because each type of communication protocol has the same protocol structure, after classifying at least two existing communication protocols, the executing body can directly acquire the protocol structure corresponding to each type of communication protocol.

In one embodiment of the present application, there is also provided a vehicle communication method that can be performed by a vehicle, and accordingly, a vehicle communication device can be provided in the vehicle, as shown with reference to fig. 11, the vehicle communication method including:

step S1110, acquiring a target protocol structure, wherein the target protocol structure is a protocol structure with the deviation degree between protocol structures corresponding to at least two existing communication protocols in the Internet of vehicles being smaller than or equal to a preset threshold value;

step S1120, determining target protocol content based on the protocol content corresponding to the used communication protocol and the target protocol structure;

step S1130, generating a target communication protocol according to the target protocol structure and the target protocol content;

step S1140, performing internet-of-vehicles communication according to the target communication protocol.

These steps are described in detail below:

step S1110, obtaining a target protocol structure, where the target protocol structure is a protocol structure with a deviation degree between protocol structures corresponding to at least two existing communication protocols in the internet of vehicles being less than or equal to a preset threshold.

In this embodiment, the executing body may acquire a target protocol structure from the network device, the target protocol structure being a protocol structure of a new communication protocol used by the executing body for switching a communication protocol currently used.

In addition, the target protocol structure is a protocol structure meeting a set condition, and the deviation degree between the protocol structures corresponding to at least two existing communication protocols in the Internet of vehicles is smaller than or equal to a preset threshold.

Step S1120, determining the target protocol content based on the protocol content corresponding to the used communication protocol and the target protocol structure.

After the executing body acquires the target protocol structure, the executing body further needs to determine the target protocol content through the protocol content corresponding to the used communication protocol and the target protocol structure. The target protocol structure and the existing protocol content are used for determining the target protocol content, so that the target protocol content is determined on the basis of fully combining the characteristics of the existing communication protocol of the vehicle, the replacement of the communication protocol is avoided, and the data loss caused by the replacement of the communication protocol can be further reduced to the greatest extent.

Step S1130, generating a target communication protocol according to the target protocol structure and the target protocol content.

It will be appreciated that the target communication protocol may be generated directly from the target protocol structure and the target protocol content.

After the executing body acquires the target communication protocol, the executing body may switch the used communication protocol to the target communication protocol, thereby performing internet of vehicles communication using the target communication protocol.

Based on the technical scheme provided by the embodiment, the vehicle in the internet of vehicles can acquire the target protocol structure, and determine the target protocol content based on the protocol content corresponding to the communication protocol used by the vehicle and the target protocol structure, so that the internet of vehicles is further communicated with the internet of vehicles according to the target protocol structure and the target protocol content, and the target communication protocol is generated.

In order to verify the effect brought by the embodiment of the application, the time delay of carrying out vehicle communication by adopting the prior art and adopting the technical scheme of the embodiment of the application is further counted in an experimental mode, the time delay comprises the time delay of packaging information to be transmitted by a vehicle according to a communication protocol used by the vehicle, a data packet of the packaged information is transmitted, other vehicles receive the data packet and analyze the total time consumed in the whole communication process of the data packet, as shown in a table 3, 10 experiments are carried out altogether, and the experimental result shows that the technical scheme of the embodiment of the application can obviously reduce the time delay of vehicle communication.
