Description
Technical field
The present invention relates to a kind of data transmission system, be specifically related to a kind of interim wireless system for transmitting data, belong to car networking technology field.
Background technology
The effect of onboard diagnostic system (On Board Diagnostic, OBD) is detect the each system operational parameters of automobile and read vehicle operation data, and its object is mainly in order to detect motor vehicle exhaust emission at first, to meet the requirement of environmental protection.Along with the development of technology, the application of OBD at present expands to the detection of complete each transducer of car and the access of vehicle-mounted computer considerably beyond simple environmental protection tests.System can enter respectively the system such as engine, gearbox by vehicle-mounted computer read failure code and other sensing data after starting, finally carry out data access by the standard OBD interface and the external equipment that are configured in steering wheel below.
Along with the development of car networking technology, increasing people begins one's study and obtains the method for travelling data from OBD interface, then transfers data to server end analysis, processes.This way can be by car owner's vehicle condition, and the data such as use habit are effectively integrated and analyzed, and can further set up data sharing with automobile production, sales service business, and valuable data message is provided.
At present, on market, there are several data analysis products based on OBD, such as Torque and scanmaster are respectively two popular in the world OBD DAS, can use at mobile phone terminal and computer end.These products all need the OBD interface that connects vehicle by hardware to obtain travelling data, then are transferred to mobile phone or computer is analyzed and shows by wired or wireless mode.Therefore, OBD interface module is key modules indispensable in whole system.Popular OBD interface module is all to obtain OBD data by the mode of bridging at present, cannot work alone.OBD interface module in this connected mode has only played the effect of bridging, need to send instruction by mobile phone or computer end software, then by bridging, instruction is sent to vehicle-mounted computer by vehicle-mounted OBD interface, the software that then vehicle-mounted computer returns to data mobile phone or computer end by OBD interface and bridging is to show data.The shortcoming of this transmission means is that software need to play transmission instruction and reception simultaneously, present the effect of data, if can consume a large amount of electric weight and affect mobile phone runnability in the time that mobile phone terminal uses.In order to obtain real-time data, mobile phone or computer need constantly and bridging module is carried out transfer of data, and this further increases computational load and the electric quantity consumption of mobile phone or computer end.In addition, because OBD interface module does not possess data storage capacities, the travelling data obtaining from vehicle-mounted computer cannot be stored in hardware end.Therefore,, even if OBD interface module is in running order, if do not opened in the program of mobile phone or computer end, travelling data cannot collected and storage.And because working procedure need to take a large amount of mobile phone resources and electric quantity consumption, user is generally reluctant to cause travelling data completely to obtain by long-time opening program.
Another kind of more novel OBD Design of Interface Module has adopted general packet radio service technology (GeneralPacket Radio Service-GPRS) or third generation digital communication technology (3
rdetc. Generation-3G) travelling data is directly uploaded to the webserver by technology, the advantage of this mode is travelling data to be directly transferred to server go forward side by side row operation and storage, but pay certain expense because this type of mechanics of communication all needs user, so promote more difficult.
