Any vehicle in example is stored with its corresponding credit grade point, also, the credit grade be divided into any vehicle from
It is obtained in the server.
Wherein, the method that the server stores the newest credit grade point can be with are as follows:
Step a stores multiple license board informations.
The license board information can be what the server was obtained from internet (such as official website of vehicle administration office), institute
State the license plate number that license board information can be vehicle.
It such as in the license board information that gets of the server may include having Shanghai A12345.
Step b stores the violation information that each license board information corresponds to vehicle, and the violation information may include act of violating regulations
And the corresponding number violating the regulations of act of violating regulations.
Wherein, the violation information that the server is stored is specifically as follows: each license board information corresponds to vehicle and exists
The violation information in the second preset time period before current point in time, second preset time period can be between half a year to one
Between year.And the violation information can be the server and be corresponded to from the official website of vehicle administration office based on license board information
It obtains.
For example, it is assumed that current point in time is 9:00 on December 24th, 2018, server will obtain license plate in current point in time
Information is that the license board information that stores is Shanghai A12345's in the violation information and official website, vehicle administration office of the vehicle of Shanghai A12345
The act of violating regulations of vehicle is as shown in table 1.As shown in Table 1, in 15:00 on December 24th, 2017, traffic-police investigates and prosecutes license board information
For the vehicle of Shanghai A12345, there are the acts of violating regulations of " not onboard driver's license ", and in 20:00 on December 20th, 2018,
Investigate and prosecute vehicle the disobeying there are " motor vehicle of turning does not allow the vehicles or pedestrians of straight trip leading " that license board information is Shanghai A12345
Zhang Hangwei.
Table 1
Further, it is assumed that second preset time period is seven months, and on this basis, the server is from vehicle administration office
The license board information that official website obtains is that the violation information of Shanghai A12345 vehicle should are as follows: in current point in time December 24 in 2018
In seven months before day 9:00, license board information is the violation information of Shanghai A12345 vehicle, be that is to say, 24 days 9 May in 2018:
Between on December 24th, 00 to 2018 9:00, license board information is the violation information of Shanghai A12345 vehicle.Specifically, the server
The license board information got is that the violation information of the vehicle of Shanghai A12345 can be as shown in table 2.
Table 2
As shown in Table 2, the license board information that the server is got is the violation information of the vehicle of Shanghai A12345 are as follows: violating the regulations
Behavior includes: " act of violating regulations 1: to interfere the motor vehicle in highway normal when motor vehicle enters highway from ring road
Traveling ", " act of violating regulations 2: not onboard driver's license ", " act of violating regulations 3: the motor vehicle of turning does not allow the vehicle or row of straight trip
People is leading ", he " act of violating regulations 4: motor vehicle is not given way by no traffic signalization crossing " and " act of violating regulations 5: drive
It is current that motor vehicle violates road traffic signal lamp "；Also, act of violating regulations 1, act of violating regulations 2, act of violating regulations 4 and act of violating regulations 5
Corresponding number violating the regulations is 1 time, and the corresponding number violating the regulations of act of violating regulations 3 is 2 times.
Step c distributes corresponding weighted value for each act of violating regulations.
Wherein, the weighted value can be positively correlated namely the act of violating regulations with the severity of the act of violating regulations
More serious, corresponding weighted value is bigger.
For example, the weighted value that the server is the distribution of each act of violating regulations can be as shown in table 3, as shown in Table 3, break rules and regulations
The corresponding weighted value of behavior " not onboard driver's license " is 0, the corresponding weighted value of act of violating regulations " driving in the wrong direction on a highway "
It is 6.
Table 3
Step d, the corresponding newest credit grade point of each license board information is calculated based on the weighted value and number violating the regulations.
Wherein, the method for calculating the license board information corresponding credit grade point can be with are as follows: license board information is corresponding every
The sum of products of the number and weighted value violating the regulations of a act of violating regulations is determined as credit grade corresponding with the license board information point.
For example, the method that server calculates the newest credit grade point that the license board information is Shanghai A12345 vehicle can be with
Are as follows: newest credit grade point=corresponding weighted value+act of violating regulations 2 of the corresponding number * act of violating regulations 1 violating the regulations of act of violating regulations 1 is right
The corresponding power of the number * act of violating regulations violating the regulations corresponding number * act of violating regulations 3 violating the regulations of 2 corresponding weighted value+act of violating regulations 3 answered
The corresponding number * violating the regulations of the corresponding weighted value+act of violating regulations 5 of the corresponding number * act of violating regulations 4 violating the regulations of weight values+act of violating regulations 4 is disobeyed
Corresponding weighted value=the 1*1+0*1+2*3+1*4+1*5=16 of Zhang Hangwei 5.
Step e, corresponding to store the license board information and newest credit grade point.
Such as server can correspond to storage license board information Shanghai A12345 and newest credit grade point 16.
It should be noted that the credit grade point is what the violation information based on vehicle calculated in the present embodiment, and
For any vehicle, violation information is simultaneously revocable, but constantly update over time, correspondingly, vehicle
Newest credit grade point is also to constantly update, and therefore, the server answers the credit grade point of its storage of real-time update, to protect
The credit grade for demonstrate,proving its storage is divided into newest credit grade point.
Specifically, it is violation information that the server, which answers real-time storage vehicle, and calculated in real time based on violation information
The newest credit grade of vehicle point, and storage corresponding with license board information, wherein the method that server stores newest credit grade point
It is detailed in step a to step e, this will not be repeated here by the present invention.
Further, in the present embodiment, any vehicle can obtain the newest credit at its current time from server
Ranking score.Wherein, the method that any vehicle obtains its newest credit grade point from server includes but is not limited to following
Two kinds:
Method one: Fig. 2 is that a certain vehicle of one embodiment of the invention method one obtains its credit grade point from server
Method flow diagram, as shown in Fig. 2, the method one can specifically include:
Step A, when a certain vehicle is in driving status, the travel distance of a certain vehicle is calculated.
Step B, when the travel distance is greater than the second preset threshold, the newest of a certain vehicle is obtained from server
Credit grade point.
Specifically, when the travel distance of a certain vehicle be greater than second preset threshold when, it is believed that it is described certain
One vehicle, which has been in, stablizes driving status, then can carry out the step of the subsequent newest credit grade for obtaining a certain vehicle point
Suddenly.Wherein, second preset threshold should be rationally arranged, second preset threshold can between 100 meters to 500 meters,
It such as can be 300 meters.
Further, a certain vehicle is specifically as follows from the method that the server obtains newest credit grade point:
Credit grade is sent to the server and divides acquisition request, and a certain vehicle is carried in the credit grade point acquisition request
License board information, then after the server receives the credit grade point acquisition request, can based on license board information determine pair
The newest credit grade answered point, and the newest credit grade point can be sent to a certain vehicle, in this way, a certain vehicle
It can get its newest credit grade point.
Method two: any vehicle periodically obtains its newest credit grade point from the server.
Specifically, any vehicle can periodically be separately won to the credit grade that server transmission carries its license board information
Request is taken, determines corresponding newest credit grade point so that server is based on the license board information, and be sent to corresponding vehicle
?.Wherein, any vehicle to server send credit grade point acquisition request period can preset, the period
Can be between 18 hours and 36 hours, such as the period can be 24 hours.
It should be noted that vehicle can obtain credit grade point from server using method one in the present embodiment, it can also
To obtain credit grade point from server using method two, credit etc. can also be obtained from server using one+method of method two
Fraction, the embodiment of the present invention is it is not limited here.
Still further, the corresponding relationship of license board information and newest credit grade point has been stored in above-mentioned server,
And be stored in any vehicle on the basis of its credit grade point, to the detection side of the threat vehicle in the embodiment of the present invention
Method is described in further detail, wherein Fig. 3 is the process of another detection method for threatening vehicle of one embodiment of the invention
Figure, as shown in figure 3, the method may include:
Step 100a, detection vehicle identifies the label of the vehicle to be detected by Radio Frequency Identification Technology, and described in acquisition
The information of vehicles stored in label, the information of vehicles include the license board information of the vehicle to be detected, credit grade point and
The last time obtains the time point of credit grade point, wherein always vehicle is most for the credit grade stored in the label of vehicle point
The credit grade point closely once got from server.
Before step 100a is discussed in detail, it should be noted that in the present embodiment, be provided with and penetrate in each vehicle
Frequency identification module, each vehicle can be communicated by radio frequency identification module with the vehicle of other in preset range, to obtain
The information of vehicles of other vehicles.Specifically, the radio frequency identification module includes reader, antenna and label, the reader
For providing the radiofrequency signal of certain transmission power, label transmission of the antenna for other vehicles into preset range is penetrated
Frequency signal, and the feedback signal of other vehicles transmission is received, the label can be used for storing the information of vehicles of vehicle, with
And the label can send automatically feedback signal to a certain vehicle, institute when receiving the radiofrequency signal that a certain vehicle is sent
State the information of vehicles for carrying in feedback signal and storing in the label.
Wherein, the preset range is the communication context of the radio frequency identification module, the preset range and the radio frequency
The transmission power of signal is related.When the transmission power of the radiofrequency signal is larger, the propagation distance of the radiofrequency signal also compared with
Greatly, correspondingly, the communication context of radio frequency identification module is also larger in vehicle.Wherein, the preset range can be with are as follows: is with vehicle
The center of circle, using the propagation distance of the vehicle radiofrequency signal as the circle of radius.
For example, when the transmission power of the radiofrequency signal of vehicle one is 10 milliwatts (dBm), the propagation of the radiofrequency signal away from
From up to 210 meters, then the communication context of one radio frequency identification module of vehicle are as follows: with the vehicle one be the center of circle, radius 210
The circle of rice.Also, the vehicle one can while be communicated in the communication context with 200 or more vehicles.
Then, in the present embodiment, each vehicle includes radio frequency identification module, and the radio frequency identification module has centainly
Communication context, the communication context are related with the transmission power for the radiofrequency signal that radio frequency identification module is sent.Also, each vehicle can
It is located in its radio frequency identification module communication context with obtaining, the information of vehicles of other vehicles.
On this basis, it describes in detail to step 100a, wherein the vehicle to be detected being previously mentioned in step 100a is
Vehicle in the communication context of detection vehicle radio frequency identification module.
Such as wherein, Fig. 4 is the location diagram of the detection vehicle and vehicle to be detected of one embodiment of the invention, such as Fig. 4
Shown, the detection vehicle can be vehicle a, and the communication context of radio frequency identification module is region b in the vehicle a, between institute
Stating the vehicle c1 in communication context b, vehicle c2, vehicle c3, vehicle c4, vehicle c5 and vehicle c6 is vehicle to be detected.
Further, the detection vehicle can obtain the vehicle letter of the vehicle to be detected based on radio frequency identification module
Breath.Specifically, detection vehicle control antenna sends radiofrequency signal to the label of vehicle to be detected, when the label of vehicle to be detected connects
When receiving the radiofrequency signal that detection vehicle is sent, the feedback signal for carrying its information of vehicles can be sent from the trend detection vehicle,
In this way, the detection vehicle can get the information of vehicles of vehicle to be detected.
It is assumed that the information of vehicles of the vehicle to be detected that gets of the detection vehicle can be with are as follows: license board information: Shanghai
A12345；Credit grade point: 16；The time point of last update credit grade point are as follows: on December 23rd, 2018 11:07.
Step 200a, it detects vehicle and calculates the time that described vehicle the last time to be detected obtains the credit grade point
The period being separated by between point and current point in time, it is determined as first time period.
For example, it is assumed that current point in time is 12:23 on December 24th, 2018, then it can learn that the first time period is 25
16 minutes hours.
Step 300a, when the first time period is less than the first preset time period, vehicle is detected by the credit grade
Divide the newest credit grade point for being determined as the vehicle to be detected.
Wherein, when the first time period is less than first preset time period, illustrate that the vehicle to be detected is nearest
The period that the time point and current point in time for once obtaining its credit grade point are separated by is shorter, and vehicle is separated in a short period of time
The probability of chapter is minimum, then the act of violating regulations of the vehicle to be detected and the probability of corresponding number variation violating the regulations are also smaller, namely should
The probability of the corresponding credit grade point variation of vehicle to be detected is also smaller, then may insure the last in the vehicle to be detected
The credit grade got is divided into newest credit grade point, therefore can be by the letter of the vehicle to be detected got in step 100a
With ranking score, it is determined as the newest credit grade point of the vehicle to be detected.Wherein, first preset time period should be less than
The period that vehicle to be detected in method two obtains credit grade point is stated, first preset time period can be less than 18 hours, example
It such as can be 12 hours.
Step 400a, when the first time period is not less than the first preset time period, vehicle is detected to the server
Newest credit grade point acquisition request is sent, the newest credit grade point acquisition request carries the vehicle of the vehicle to be detected
Board information.
Wherein, when the first time period is not less than first preset time period, illustrate the vehicle to be detected most
Time point and the current point in time interval time section for closely once obtaining its credit grade point are longer, and vehicle is disobeyed in long period
The probability of chapter is higher, then the act of violating regulations of the vehicle to be detected and the probability of corresponding number variation violating the regulations are also higher, namely should
The probability of the corresponding credit grade point variation of vehicle to be detected is also higher, that is to say, that the vehicle the last time to be detected obtains
Credit grade point may not be newest credit grade point.And due to being surveyed based on newest credit grade sorting in subsequent step
Vehicle is threatened, so just can ensure that the accuracy for threatening vehicle detection, therefore, the detection vehicle needs are obtained from server
The newest credit grade point of the vehicle to be detected is taken, to guarantee to threaten the accuracy of vehicle detection.
Step 500a, the described server based on the newest credit grade point acquisition request got determine it is described to
Detect the newest credit grade point of vehicle.
Specifically, the server separately wins the vehicle for taking vehicle to be detected described in request based on the newest credit grade
Board information, then corresponding newest credit grade point is determined based on the license board information.
Step 600a, the newest credit grade of the vehicle to be detected point is sent to the detection vehicle by the described server
?.
With reference to above-mentioned steps 300a~600a it is found that being by whether judging the first time period in the embodiment of the present invention
Less than first preset time period, to judge whether is credit grade point that the detection vehicle is obtained from the vehicle to be detected
For newest credit grade point, wherein when judging result is certainly, the detection vehicle directly obtains it from vehicle to be detected
Credit grade point be determined as newest credit grade point, no longer need to the newest credit that the vehicle to be detected is obtained from server
Ranking score, and divide longer, of the invention side of required time since detection vehicle obtains newest credit grade from server
Method saves the detection time for threatening vehicle to a certain extent, improves the detection efficiency for threatening vehicle.
Step 700a, detection vehicle is determined based on the newest credit grade point whether there is prestige in the vehicle to be detected
Coerce vehicle.
Wherein, newest credit grade point is determined as threatening vehicle greater than the vehicle to be detected of the first preset threshold.It is described
First preset threshold should be rationally arranged, and first preset threshold can be between 10 to 15, for example, described first is default
Threshold value can be 12.
Step 800a, vehicle is threatened if it exists, detection vehicle is by Radio Frequency Identification Technology described in threaten and obtain in vehicle
Threaten the location information of vehicle.
Specifically, when detect vehicle detection go out exist around it threaten vehicle when, can be by radio frequency identification module to described
It threatens vehicle to send location information acquisition request, so that the threat vehicle is based on the location information acquisition request, obtains it and work as
Preceding location information, and it is sent to detection vehicle.Wherein, the location information for threatening vehicle may include the threat vehicle
Geographical coordinate.
And the method for threatening vehicle to obtain its current location information may include: to pass through global positioning system
(Global Positioning System, GPS) is obtained, alternatively, passing through base station location method (Location Based
Service, LBS) it obtains.
It should be noted that in the present embodiment, it is preferred that vehicle is threatened to obtain its position letter by GPS positioning method
Breath.Wherein, it threatens and locating module (such as GPS module) is installed in the terminal of vehicle, when locating module is opened, can get
The GPS signal that satellite system is sent, its location information can be got by threatening vehicle to be based on the GPS signal.
But it when the threat vehicle is located at the weaker place of GPS signal (such as tunnel or bridge), is then not easy to
The location information of vehicle is obtained using the GPS positioning method, at this point it is possible to obtain the threat vehicle by LBS positioning mode
Location information.
Wherein, the LBS positioning mode is specifically as follows more radio frequency identifications (Radio Frequency
Identification, RFID) base station location method, this method needs first to establish multiple base stations RFID, also, each base station
Geographical coordinate known to.Based on this, threaten vehicle can be with by the method that more RFID base station location methods obtain its geographical coordinate are as follows:
