Referring to fig. 2, protocol conversion illustraton of model
The board information terminal of different vehicles can read the information of car body control module BCM by CAN interface, read
BCM information is converted to middleware communication protocol format by message conversion module, it is converted after information be sent to middleware and disappear
Bus is ceased, (main include mobile terminal application, vehicle enterprise Remote Terminals for Weather Servics, other service terminals to the application of most Zhongdao car networking
Car networking application program), message also can be transmitted to board information terminal in car networking application, passes through middleware protocols conversion module
Car body control module is handed down to after conversion.Background service is protocol conversion module to different agreement with the key that vehicle body can communicate
Mutual conversion.
The a part of protocol conversion module as car networking middleware, interface one end are vehicle body CAN bus, and the other end is
Middleware messaging bus.CAN communication bus network is connected on specific In-vehicle networking by CAN transceiver；Middleware message
Bus is a virtual bus, is connected to the various communication components and application component of middleware thereon, and each component passes through this void
Quasi- messaging bus is communicated.Wherein the description of CAN communication agreement is described using the CAN application protocol standard of Vector company
Method DBC file describes method；DBC file include node, variable start bit, stop position, range, offset etc. be enough to describe and
Analyze the Global Information of a CAN network.MATLAB and the CAN bus protocal analysis test software CANoe of mainstream etc. are supported
The file of such format.Middleware communication agreement uses next generation car networking agreement NGTP (Next Generation
Telematics Protocol) custom protocol under protocol frame.
Referring to Fig. 3, protocol conversion mapping graph；
Conversion map mainly includes the conversion on 2 directions, that is, sends and receive process.In transmission flow, middleware association
View distinguishes the message for being sent to different components by the parsing of function code and function subcode, such as function code in column right in the following table 4
4001 are sent to the message of vehicle body with the combination expression of function subcode 1001；Separately there is the combination of code 4001 and function subcode 2001 to indicate
It is sent to the message of engine.Then it is determined according to the information of data field and is sent to the specific component of vehicle sound, that is, determine the CAN sent
Specific set and the position in frame is reset in message.Data field 17 indicates that high beam control is opened in table 4, is mapped to vehicle body CAN
Agreement is that ID is 7A0, and the 0-1 of Section 1 of 8 bytes of data frame is to set 1.Receive the opposite process that process is transmission flow, root
The value of function code and data field is determined according to the parsing of the position state in 8 bytes of vehicle body CAN protocol ID and data frame.

The database manipulation class that Eclipse is provided is write SQL standard scripting language and is operated to data.
Referring to Fig. 5 protocol configuration flow chart
Vehicle enterprise completes the configuration of agreement according to protocol configuration flow chart, creates after starting configuration tool or importing one existing
Configuration information, describe in configuration tool to configure protocol information and select according to the CAN protocol of target vehicle corresponding
Protocol conversion Code Template file.The parameter of configuration contains the corresponding relationship of middleware protocols Yu vehicle body CAN protocol, corresponding
Relationship is matched by name variable.Such as the following table 5, configured with the entitled standard of the variable of middleware protocols defined.It is selecting
In the correspondence vehicle body CAN protocol of different middleware standard agreements, according to the agreement of the list item configuration vehicle body of regulation.
5 configuration item Verbose Listing of table
Check the correctness of configuration after the completion, including whether CAN beacon information is correct, whether CAN data information repeats, mould
Whether plate is correct.Check that the errorless rear real time workshop for clicking configuration tool, the code of generation are compiled under Target compiling environment
Translate generation protocol conversion module.Protocol conversion module is installed to realization car networking protocol conversion on board information terminal, is realized
Communicate two-way interactive.Wherein CAN receives and dispatches function and uses SocketCAN standard interface.
3) protocol conversion stencil design
Protocol conversion template file is the mother matrix of final code, and the whole codes for containing protocol conversion are realized, specific to wrap
Code skeleton file containing protocol conversion.It ensure that the correctness and reliability of final code.
Referring to Fig. 6 protocol conversion template file flow chart and Fig. 7 protocol conversion template UML sequence chart
The major function of template is exactly that specified message is obtained from CAN network, extracts useful part and is encapsulated as middleware mark
Quasiconfiguaration is sent to middleware messaging bus and opposite process and the control instruction that messaging bus is sent is converted to CAN report
Text formats.Wherein change data is carried out during transmitting-receiving, and it is inquiry that data are received for application program
Process, sending data is control process.
Information protocol-dependent in code is extracted to the parameter as template.The parameter of template passes through configuration tool
Configuration information is calculated.Protocol conversion template program flow chart as shown, main function be entire template program entrance,
Protocol conversion template program mainly includes the transmitting-receiving of message, i.e., mainly sends thread and receive_ comprising send_threadfun
Threadfun receiving thread, main task concentrate on the reception process of message, and receiving thread processing, which refers to, receives messaging bus
The message sended over, and then handled, including control message, query messages and emergency message, correspond respectively to institute in figure
The control flow shown, querying flow and urgent process.Template file, which is adopted, to be shown a C language, and dynamic link library is finally compiled as, with
Guarantee versatility and the replaceability in linux system and android system.
Since it is desired that obtaining vehicle body state to fill the shape of non-controlling position in this message in the calculating process of control flow
State, so containing the process of querying flow.Such as preceding 2 expressions vehicle window control bit in binary digit 0101, rear two expressions
High beam control bit, when controlling operation to high beam, preceding 2 vehicle window control bits are the non-controlling position that this CAN controls message,
It needs to keep original state, so needing to inquire original vehicle window control bit state before CAN control message is issued to bus.Ginseng
See Fig. 7 protocol conversion template UML sequence chart, typical case's control message calculation process is as follows:
(1) middleware messaging bus sends control command to communication component, and the major function of communication component is exactly that agreement turns
It changes.
(2) it parses, message is split according to the definition of background message, judge to need the control bit that controls, as high beam is opened, and
According to the mask that the obtained control mask of configuration is controlled, such as high beam _ open control code 0x0000000000000001 (standard
Data frame 64).
(3) CAN query message is sent, and inquires the state of other control bits in primary current control bit association message, and CAN is looked into
Message is ask to return to obtain status code 0x0000000000000010.
(4) status code with control mask phase or
High beam _ open control mask | | the data field 0x0000000000000011 that status code is sent.
(5) data field and CANID CAN data frame is packaged into be sent in bus by CAN interface.
Fragment in the internet and reorganization operation be because the MTU value of different communication networks is different, and the fragment in figure and
Reorganization operation is to correspond to different CAN network nodes because of information needed for middleware messaging bus protocol data domain,
It needs to separate request data, inquires combination again after receiving returned data parsing.
4) real time workshop
The specific code details that source code can make user that need not understand middleware code is automatically generated, is more convenient to generate
Qualified code, is saved the time for us, reduces complexity, shortens the development cycle.
Referring to Fig. 8 Code automatic build figure
Although it is very powerful that machine automatically generates source code, being inserted into code into program will become very complicated, very
Indigestibility.Having a kind of method that can reduce complexity, that is exactly to use template with readability is increased.
In Eclipse modeling framework (EMF) project, include two very powerful tools for being used to generate source code:
JET (JavaEmitter Templates) and JMerge (Java Merge).Using JET code generating method in eclipse with
The form that character string passes ginseng carries out the generation of code.Since the code of generation needs to provide communication interface for messaging bus, and it is logical
Agreement nonstandardized technique is believed, so code legibility is guaranteed using the code generating method based on template.
As shown, the process of Code automatic build is to define a template, it is intermediate by JET engine generation java,
It is intermediate to have generate method, character string code is ultimately generated according to configuration parameter.From the point of view of user, do not know usually
Road JET engine and intermediate presence, it is only necessary to which editing template code is passed to configuration parameter, generates generation using intermediate method
Code file.
As shown in lower template simple examples, for the switch control of dipped headlight and high beam, the incoming parameter of code is
Argument, is a list array, and array contains the parameter of all transmitting.
According to the code ultimately generated above are as follows:
The resulting CAN application protocol information of configuration is wherein contained in 16 system fields.For example, when control high beam is opened,
The value of variable FFMask_State_NearLight_open1 is sent, minimum 2 byte is 0xC1, other high bytes are according to inquiry shape
State filling.
In code generation process, configuration parameter is to ultimately generate the basis of code in figure, the parameter of code building transmitting
Mainly have:
Digital quantity: parameter includes that the control (state) of complete 1 mask and each variable of this digital quantity in CAN message information is covered
Code.These masks are all the parameters of user configuration by condition query, displacement, with or wait obtained from calculating operations.
Analog quantity: parameter includes complete 1 mask of this analog quantity in CAN message information and the side for handling this original analog amount
Method.Such as integer, single-precision floating point or double-precision floating point processing.
Other: CAN communication interface function may when protocol conversion module reads a little different platform CAN bus information
Interface is read using different CAN.
The code file ultimately produced is the combination of c file and h file, in the auxiliary of compiling link file and make tool
Under automatically generate file destination.
The above, only best mode for carrying out the invention, anyone skilled in the art is in the present invention
In the technical scope of disclosure, the simple change or equivalence replacement for the technical solution that can be become apparent to each fall within of the invention
In protection scope.
