With reference to Fig. 1, which includes: at least one car-mounted terminal 14, data acquisition platform clothes
Business device 13, Web server 12, database 15, Streaming Media forwarding server 16；The car-mounted terminal 14 is used to record the friendship of vehicle
Logical data；
The Web server 12 is used to receive the data requesting instructions for car-mounted terminal 14 of the transmission of user terminal 11,
And the data requesting instructions are forwarded to car-mounted terminal 14 by data acquisition platform server 13, so that the car-mounted terminal
14 provide corresponding data；
The data acquisition platform server 13 receives the traffic data that the car-mounted terminal 14 is sent, by the traffic number
According in the deposit database 15；The Web server 12 obtains the traffic data from the database 15；
The Web server 12 is also used to request to the Streaming Media to forward to service according to the monitoring that user terminal 11 is sent
Device 16, to obtain the real-time video flow data of default car-mounted terminal 14 by the Streaming Media forwarding server 16.
Car-mounted terminal 14 is set on vehicle arrangement, a kind of terminal device of the traffic condition for recording vehicle.This is vehicle-mounted
Terminal 14 can be automobile data recorder.
Web server 12 is Website server, for being directly that user terminal 11 provides data.User can be in user terminal
11 obtain the traffic data needed from Web server 12 by browser.The user terminal 11 can be personal computer, intelligence
The equipment such as energy mobile phone.
Web server 12 can send data requesting instructions to car-mounted terminal 14 by data acquisition platform server 13；Vehicle
Mounted terminal 14 returns to corresponding traffic data to data acquisition platform server 13 in response to the data requesting instructions；Data
The traffic data storage that acquisition platform server 13 returns to car-mounted terminal 14 is in database 15；Web server 12 is from data
Corresponding traffic data is obtained in library 15.On user terminal 11 corresponding friendship can be obtained from Web server 12 by browser
Logical data.
The car-mounted terminal 14 can also be spontaneous carry out data upload, be stored in by data acquisition platform server 13
In database 15, obtained for Web server 12.
In some embodiments, Web server 12 is before data requesting instructions are sent, by the request of data
Instruction is converted into meeting the command format of preset standard.
Data requesting instructions are standardized, so that the car-mounted terminal 14 for meeting the preset standard can recognize the data
Request instruction.
In some embodiments, preset standard is 808 standard of JT/T, is specifically as follows: JT/T808-2011, road
Haulage vehicle global position system terminal called agreement and data format.
Car-mounted terminal 14 meets 808 standard of JT/T, and Web server 12 will be from various types of user terminals 11

Data acquisition platform server 13 returns to confirmation instruction to confirm the authentication information of car-mounted terminal 14.
In some embodiments, when car-mounted terminal 14 is when needing to report hydropac information, the data acquisition is flat
Platform server 13 receives the hydropac data that the car-mounted terminal 14 uploads, and provides the long-range visit of the hydropac data
Interface is asked, so that the Web server 12 passes through the remote access interface from the memory of data acquisition platform server 13
Obtain the hydropac data.
Data acquisition platform server 13 receives the hydropac data that the car-mounted terminal 14 uploads, and provides long-range
Access interface, the Web server 12 obtain the hydropac data for remote access interface by this.Wherein, the danger
Dangerous data with alert is stored in the memory of data acquisition platform server 13.
Specifically, the mode being directly accessed by internal storage data, the real-time acquisition for realizing hydropac data are prolonged with low
Push late.
Specifically, data acquisition platform server 13 goes publication for remote access by public interface release manager
Interface；And different functions is realized to the interface of each publication, and increase the persistence function of memory object, so that all logical
The memory object for crossing interface access can persist.
Web server 12 passes through the interface proxy device of remote method factory (RMI) class, is localling create remote method interface
It is local realize (realizing in a manner of interface proxy), and realize persistence, object transmitted in a network.
Web server 12 accesses the specific implementation object of the interface of distance host class as access native object.In turn
The access and transmission for realizing data, get the hydropac data.
In some embodiments, the Web server 12 is also used to manage the data in the output library, including basis
Information data.
It should be noted that traffic data is data detected by car-mounted terminal 14, it may include video, audio, various
Data detected by sensor.The traffic data may include hydropac data and video stream data, pass through each path
The traffic data of transmission can be adjusted according to the actual situation.
In short, the data transmission system of the car-mounted terminal 14 is when transmitting different data, using different transmission mode and
Transmission path is realized for example, transmitting real-time video flow data by Streaming Media forwarding server by shared data in memory
The push of the low latency of dangerous warning information obtains, other traffic datas are accessed by database.It, should for different data
Car-mounted terminal data transmission system is transmitted using different transmission mode and transmission path, to improve entire car-mounted terminal
The efficiency of transmission and data throughout of data transmission system.
On the other hand, the embodiment of the present application also shows a kind of car-mounted terminal data transmission method, the car-mounted terminal data
Transmission method be applied to Web server, with reference to Fig. 2, the car-mounted terminal data transmission method comprising steps of
Step S101, Web server receive the data requesting instructions for car-mounted terminal that user terminal is sent, and by institute
It states data requesting instructions and car-mounted terminal is forwarded to by data acquisition platform server, so that the car-mounted terminal provides accordingly
Data；
Step S102a, the data acquisition platform server receive the traffic data that the car-mounted terminal is sent, will be described
