Claims (10)

1. A vehicle-mounted ad hoc network method based on service requirements, the method comprising:
acquiring service demands of automobile owners in a preset area in a preset time range, and taking the automobile owners with the quantity of the service demands reaching a first set threshold as users meeting networking conditions;
counting the number of users meeting networking conditions, and determining an initial networking family according to the number of users meeting networking conditions;
sending inquiry information about whether to agree with networking to users in an initial networking group, counting the users agreeing with networking, and classifying the users agreeing with networking into the networking group;
and generating an initial networking scheme based on the service requirements of the users in the networking group, and transmitting the initial networking scheme to the users in the networking group.
2. The method of claim 1, wherein the counting the number of users meeting the networking condition, and determining the initial networking family based on the number of users meeting the networking condition comprises:
if the number of users meeting the networking conditions is larger than a second set threshold value but smaller than a third set threshold value, classifying the users meeting the networking conditions into an initial networking group, and forming the initial networking group: f (k) =tsnk; wherein T is formation time, S is area and position of the area, N is successful number after networking, and K is the kth formation every day.
3. The method according to claim 2, wherein the method further comprises:
and acquiring a modification instruction of a user in the networking family for the initial networking scheme, and modifying the initial networking scheme according to the modification instruction to generate an optimal networking scheme.
4. A method according to claim 3, characterized in that the method further comprises:
acquiring a characteristic authority level of a user vehicle in a networking family; wherein the feature authority level comprises: primary feature authority level, intermediate feature authority level, and advanced feature authority level;
and matching private keys in a unified rule base of the server according to the characteristic authority level to encrypt the characteristic authority level.
5. The method of claim 4, wherein matching private keys in a server unified rule base based on the feature authority level encrypts the feature authority level, comprising:
the primary characteristic authority level is not encrypted;
the software algorithm random number is adopted to provide a random key to encrypt the medium-level characteristic authority level;
and a quantum cryptography algorithm and quantum key distribution are adopted to provide a random key to encrypt the advanced feature authority level.
6. The method according to claim 1, wherein the method further comprises:
and performing performance matching test and intelligent computing capability evaluation on each user vehicle in the networking family.
7. The method according to any one of claims 1 to 6, further comprising: when the exit request of the user in the networking family is obtained, the number of the user in the networking family is recalculated;
when the number of users in the networking group is not less than the preset number of users, continuing to maintain the networking state;
otherwise, the networking is ended.
8. A vehicle-mounted ad hoc network device based on service requirements, the device comprising:
the acquisition module is used for acquiring service requirements of automobile owners in a preset area in a preset time range, and taking the automobile owners with the number of the service requirements reaching a first set threshold as users meeting networking conditions;
the determining module is used for counting the number of the users meeting the networking conditions and determining an initial networking family according to the number of the users meeting the networking conditions;
the statistics module is used for sending inquiry information about whether networking is agreed to users in the initial networking group, and counting the users who agree to networking, and classifying the users who agree to networking into the networking group;
and the generating module is used for generating an initial networking scheme based on the service requirement of the user in the networking group and transmitting the initial networking scheme to the user in the networking group.
9. A processor configured to perform the service requirement based on-board ad hoc network method according to any one of claims 1 to 7.
10. A machine-readable storage medium having instructions stored thereon, which when executed by a processor, cause the processor to be configured to perform the service requirement based on-vehicle ad hoc network method of any one of claims 1 to 7.
