Car-mounted terminal sends data through the GPRS radio-cell through the go forward side by side line data reorganization of the core data of CAN bus collection vehicle at last.As shown in Figure 1; Data are at first imported base station controller BSC into through base station transceiver BTS; Get into GPRS serving GPRS support node SGSN then, SGSN is connected to GGSN GGSN through the GPRS backbone network, and then data flow into the Internet network through GGSN; Be sent to the server of far-end according to IP and port numbers, by the server end application software data carried out Treatment Analysis more at last.Simultaneously; The mode that increases the USB flash disk storage at car-mounted terminal prevents the error in data that data cause the data transmission lag to cause because of network condition: when vehicle gets into busier period of the more weak area of network signal or network service; Car-mounted terminal earlier with the storage that collects in USB flash disk; Again data are sent in the time of etc. network condition preferably, guaranteed stability and accuracy that data are sent.
The core data of mainly accomplishing the vehicle that car-mounted terminal is sended over as the upper computer software of remote monitoring center server end receives; And utilize preset data protocol to decode; With storage in database; So that carry out data management and playback, can also carry out management such as data transmission to lower floor a plurality of remote vehicles terminal.Upper computer software can be divided into following functional unit:
1, user authority management unit, software systems are to guarantee the having distributed user of authority in the privilege feature scope, to use this software.When system moved, the user need import username and password in the system management window, the different rights of using of different users and the then corresponding upper computer software function of authority.
2, Data Receiving/transmitting element utilizes the Internet programming technique to programme, and can receive the data that many cars send over simultaneously, also can send parameter and instruction to many chassis simultaneously, the data interaction of control vehicle termination.
3, data processing unit, its initial data that system is received is decoded according to the data protocol that has set and is stored in the database, for data management and playback function are prepared.
4, data readback unit is used for according to user's requirement Various types of data being shown with forms such as charts, supplies the researcher to carry out diagnostic analysis.
5, agreement is provided with the unit, can under the situation of manufacturer data protocol modification, revise the software data agreement as required, to adapt to the needs of data acquisition under the different CAN agreements.
The service data long distance control system in the hybrid vehicle of the present invention and the advantage of method are embodied in:
1, the offline storage function is that data analysis and fault investigation in the vehicle R&D process provides the data support;
2 utilize wireless network that vehicle operating parameters is carried out remote transmission, have overcome the region and the distance limit of collection in worksite, have improved efficient and convenience;
3, agreement is provided with function development and has solved the present situation that a cover system can only carry out data processing to a certain specific protocol, has improved the versatility of system.
Service data long distance control system and method in the hybrid vehicle of this invention have been adopted; Its system comprises vehicle carried data collecting slave computer module and the data analysis upper computer module that connects through wireless network or cable network, and this vehicle carried data collecting slave computer module also connects the control bus of hybrid vehicle.Thereby after the service data of described vehicle carried data collecting slave computer module through the control bus acquisition hybrid vehicle of described hybrid vehicle; Can described service data be sent to described data analysis upper computer module through wireless network or cable network, supply the data analysis upper computer module to analyze and preserve.Realize function such as remote analysis processing, playback thus, and the service data long distance control system in the hybrid vehicle of the present invention and method have higher convenience and versatility to vehicle operation data.
In this specification, the present invention is described with reference to its certain embodiments.But, still can make various modifications and conversion obviously and not deviate from the spirit and scope of the present invention.Therefore, specification and accompanying drawing are regarded in an illustrative, rather than a restrictive.
