The workflow of vehicle termination and server is as shown in figure 14.
Present embodiment also provides a kind of driver's fingerprint individual verification and localization method, including：
Step 1, server and vehicle termination carry out initialization connection；
Vehicle termination carries out initialization by second communication module with server by first communication module and connect, and method is such as
Under：
(1) vehicle termination sends the data packet (TCP connection data packet) of active Connection Service device, sends out connection request：Such as
Fruit cannot connect to the response that server does not receive server, wait for 5s to send the data packet again, until successful connection knot
Beam；At the same time, server is constantly in the stage for monitoring the data packet messages, monitors whether that the connection of vehicle termination is asked
It asks.
(2) it after server receives connection request, by TCP three-way handshake process, establishes and communicates with vehicle termination, at this time
Vehicle termination and server successful connection.This procedure ensures that customer terminal equipment can Connection Service device, but the two cannot
Into row data communication；If to also need to carry out registration verification operation into row data communication, vehicle termination.

Vehicle termination and server initiation connection procedure allow vehicle termination to be connected to server and can phase
Mutual transmission data only first completes the process, could carry out the operations such as fingerprint authentication, otherwise vehicle termination can not with server into
Row data interaction；Fingerprint authentication can just carry out the process with processing after initializing connection procedure, and otherwise server can not be rung
Answer the requests such as vehicle termination verification.The data interaction of vehicle termination and server, vehicle termination have been all referred in these flows
It is as shown in Figure 7 with the data interaction of server.In the data exchange process of vehicle termination and server, mainly grasped comprising terminal
Make, operating parameter update verification, fingerprint authentication download is deleted and the behaviour such as position data and state transfer, high temperature overspeed alarming
Make.These operations and non-sequential progress, but carry out " asynchronous process ", i.e. server and vehicle termination needs to open up multiple lines
Journey.When a kind of operation is carrying out, if there is another kind operation needs to carry out, then the operation can transfer to multiple threads,
It need not wait for.Due to there is no sequencing between these operations.
Step 2 carries out information registering and management according to the driver information of typing；Specifically server is according to the fingerprint of typing
And its corresponding personal information, fingerprint database is established for current driver, and the fingerprint of each driver and a is stored with this
People's information；The information of vehicles that driver information is driven with it is bound, driver information is distributed to corresponding vehicle termination；
Step 3, server and vehicle termination are in listening state, carry out data interaction；
The data interaction, including：
(1) when the fingerprint quantity of server and vehicle termination mismatches, fingerprint template update behaviour as shown in Figure 10 is carried out
Make：
When the fingerprint quantity of server and vehicle termination mismatches, vehicle termination needs to re-download vehicle termination correspondence
Fingerprint template；If the fingerprint database in server occurs modification, increases, delete operation, corresponding vehicle termination needs
Carry out fingerprint update (increase, modification or delete operation).It is the update operation of vehicle termination fingerprint template below.The update operates
It can check whether to need to update first, the operations such as the download of progress fingerprint template are then determined according to the situation.
1) first, vehicle termination according to the SYN that receives confirm " verifying fingerprint data mark " in packet result (verification at
Work(or failure) construction " server parameter is updated replys packet with verification confirmation " (TOK heartbeat packets).And vehicle termination is by the TOK hearts
It jumps packet and is sent to server.
SYN confirm packet voice information in include " verifying fingerprint data mark ", the mark representative server database with it is right
Whether the fingerprint in the fingerprint identification module answered changes.
2) after server receives the data packet that vehicle termination is sent, first determine whether that the data packet is which type of vehicle
Terminal data packet.When data packet is TOK heartbeat packets, server is operated according to " more new state " field in TOK packets：
When " more new state " field is FAILURE, verification failure is represented, then server is whole according to vehicle in the TOK packets
Fingerprint template, is then packaged in that " fingerprint template issues and deletion refers to by the user fingerprints that are associated in the ID inquiry databases of end
In line template " data packet, the data packet is sent to vehicle termination, since terminal may preserve multiple fingerprint templates, it is therefore desirable to
Multiple fingerprint template data packets are constructed to be transmitted；When " more new state " field is SUCCESS, server does not do any place
Reason, the renewal process are completed.
It is specifically intended that since fingerprint length is 512 bytes, the transmission of a fingerprint template can be divided into two
Data packet is transmitted.
3) when vehicle termination receives " fingerprint template issues and delete fingerprint template " data packet, vehicle termination is according to this
Fingerprint template data in data packet, the fingerprint storage content in the driver identification ID update microcontrollers corresponding to fingerprint；And
It will be updated successfully or the result of failure be sent to server by " fingerprint template issues and delete replying state " data packet.
4) when server receives " fingerprint template issues and the delete replying state " data packet, according to data packet weight
Device id and the update associated database of status modifier server.So far, fingerprint template updates end of operation.Fingerprint template
More new technological process is illustrated in fig. 10 shown below.
It is specifically intended that：When initialization procedure is completed, which can also be first carried out once, then every 5s this more
New technological process will be triggered；Using which first in order to which whether real-time inspection server finger print information changes；Second real
When check whether that vehicle termination is connect with server.In case of opening operation, need to re-execute initialization attended operation.Separately
Outside, the case where changing for key parameter, after server changes, only when re-starting vehicle termination connection and registration operation
The parameter of (initialization procedure), change can be just issued in vehicle termination equipment, this is consistency and safety in order to protect data
Property.
(2) vehicle termination periodically carries out data upload operation：
Vehicle termination is every T1When (default setting 120s), " data upload " DAT packets are uploaded to server, wherein including
At the time of latitude and longitude information, vehicle heading and the speed of GPS module positioning, traveling, mileage and signal strength information.
When detecting overspeed of vehicle, vehicle termination uploads overspeed warning packet (SPE packets) to server.When temperature sensor detects
Heat alert packet (TMP packets) is sent when environment temperature is higher than setting value in compartment to server.
It is that these wrap the operating process sent and received below：
A. latitude and longitude information (vehicle location information) uploads, as shown in figure 11：
1) as each timing T of vehicle termination1When, vehicle termination is positioned according to the longitude and latitude that the GPS module being accessed provides
Information calculates relevant speed, and uploads packet (DAT packets) according to these information structuring data, is then sent to server.
2) when server receives the DAT packets, device id, latitude and longitude information, speed, direction and the time in packet are parsed
Etc. information, and latitude and longitude information, velocity information etc. in real-time update server in database table.Then, it sends and " confirms back
Data packet gives device id corresponding client terminal again ", and notice uploads successfully.
3) it after vehicle termination receives " the confirming reply " packet, is not processed.
B. hypervelocity warning information uploads, as shown in figure 12：
1) per timing T in vehicle travel process1When, vehicle termination is according to the latitude and longitude information and duration meter of GPS positioning
The average speed of current vehicle traveling is calculated, if the vehicle average speed is more than the threshold speed of setting, sends hypervelocity police
It reports data packet (SPE data packets) to server, allows server to carry out hypervelocity alarm and show and handle；Otherwise any place is not done
Reason, continues to monitor.
2) when server receives hypervelocity alarm data packet, according to the longitude and latitude, average speed, associated in the data packet
Vehicle termination ID number inquires associated vehicle, the specifying information of the overspeed of vehicle is shown in the management platform of server, and
It records in the hypervelocity alarm to log information.
C. heat alert information：
1) when temperature sensor detects that current compartment inner ring border temperature is more than temperature threshold, vehicle termination sends high temperature report
Alert data packet (TMP data packets) gives server；If it does not exceed the threshold, it is without any processing, continue to monitor.
2) when server receives high temperature alarm data packet, server admin platform shows heat alert, and records
In the heat alert to log information.
It is specifically intended that：Above-mentioned data packet uploads no sequencing；These three data packets are transmitted whenever being triggered to
When condition, vehicle termination transmission data packet, and transfer to server process.Heat alert processing is consistent with hypervelocity alarm processing,
It is not given here heat alert process flow.
(3) vehicle termination fingerprint recognition flow, as shown in figure 13：
1) after the completion of vehicle termination identification, vehicle termination sends " fingerprint recognition state " data packet and (is proved to be successful mark
It is proved to be successful, failure then marks authentication failed) to server；After server receives the data packet, according to vehicle termination ID,
The relation table of fingerprint ID and fingerprint recognition result phase update fingerprint and vehicle termination；After the completion of update, server, which is sent, " to return
Fingerprint authentication result is acknowledged receipt of again " for data packet to corresponding vehicle termination, notice vehicle termination has received fingerprint recognition shape
State data packet.
2) it is without any processing after vehicle termination receives the fingerprint recognition state data packets that server is sent.It continues to execute
Other flows.
In vehicle termination fingerprint identification process, the update of above-mentioned fingerprint template, data upload, vehicle termination fingerprint recognition
Flow is divided according to the data interaction flow of vehicle termination and server.In fact, working as vehicle termination and server
After completing connection and registration operation, server is in listening state, when listening to data packet and passing over, can judge to transmit
Which kind of data packet what is come is, the processing procedure of the data packet is then executed according to data packet type.After being disposed, server is again
In listening state, the appearance of next data packet is waited for.Fig. 9 is vehicle termination and server working method.
The problem of in order to which the processing of vehicle termination transmission data real-time and load balancing is effectively relieved, in server and vehicle
When terminal processes data packet, multithreading is used to alleviate data payload problem：It is handled in server or vehicle termination
During some data packet, a data packet is had received again suddenly, cannot wait for finish reprocessing at this time, needs to open up another
One thread is handled；In server, since there are multiple vehicle terminations to carry out data packet transmission and processing, server
It needs to open up thread for each vehicle termination to handle corresponding flow.The previous case, which opens up two threads, to be located
Manage the situation；And latter needs to open up thread according to the number of vehicle termination.
In the entire system, several points need to pay attention to：
(1) it when vehicle termination and server disconnect, if needing to connect again, needs to re-execute connection registration behaviour
Make；
(2) during the work time, vehicle termination can judge whether vehicle termination breaks with two side of server at regular intervals
Open connection；After hours, vehicle termination power-off is closed.Either connection or disconnection is all vehicle termination actively to service
The operation that device carries out.
(3) exceed the speed limit alarm and heat alert what influence no on vehicle termination；Server can record day according to alarm
Will and display exception information, to be managed.
Data packet format explanation in fingerprint recognition and positioning system and method：
(1) vehicle termination registration request (signaling：REG)
This data packet is sent when each vehicle termination establishes successful connection with server, and interval time sends for 5s
Once, (finger that succeeds in registration here succeeds in registration or has succeeded before for the first time until server, which returns, to succeed in registration
It registered).
Such as：#:REG | 866699025813256 |+8613612345678,20 | (check value) | V1.0*
Fingerprint quantity：n
(2) operating parameter update and verification (signaling：SYN)
This information server after terminal establishes successful connection and sends log-on message returns to notebook data packet, in addition takes
Business device parameter also issues when changing.
Parameter update mark：0 indicates not updating 1 expression update
