Description
Technical field
Many industrial circles are all experienced the pressure that must shorten its development time, and meanwhile they will develop the product of uniqueness and innovation.Succeed in the world market, these two factors are that inevitably particularly for high-tech enterprise such as automobile, aviation and the communications field, in these enterprises, Electronic Control/adjusting is the part that plays a decisive role of new product.
This control or adjusting be a kind of approach of time saving, high performance-price ratio based on Model Design because control/regulation technology is by single model work, this model comprises a kind of function or a complete system in single integrated software environment.Performance history based on model has brought up the system that optimizes and fully test, and wherein works in coordination each component optimization.Can use for regulator modeling in the software part and behavior modeling as MathWorks
With the such instrument of the TargetLink of dSPACE.For check regulator model in actual environment, can be integrated in it in the prototype system.TargetLink is suitable for the design software parts in addition, and these software parts are used for system architecture software, especially for the SystemDesk based on Model Design that is used for system level of dSPACE.In SystemDesk, a plurality of software parts can make up, and to constitute a software architecture, its part that can be used as the total system model is used.
Can use tool master in the prior art, as MathWorks
For the opertaing device test is carried out modeling and is therefore produced behavior model for opertaing device function, diagnostic function and realistic model with graphics mode.Here on same model basis, work mostly, and with the validity of the present whether function in the checking automobile, whether be whether Serial Control equipment generating code or test are carried out in ring environment (Hardware-in-the-loop-Umgebung) at hardware and had nothing to do.
Behavior model is usually with the graphics mode modelling, and the user can embed the C code of oneself in the functional block (Block) of graphics mode here.
In order to carry out communicating by letter of model and other electronic equipments by the bus as CAN, LIN or FlexRay bus, can be in the special functional block incorporation model.This functional block is structured in the model, and this model can be exchanged messages by corresponding bus and other system.The receiving function piece carries out pre-service so that handle to the data that receive from hardware model.The sending function piece carries out pre-service so that send by bus to information.For the message that will send, typically some parameters can be set.These parameters for example are
Send the selection of the controller of message
In the functional block sampling time, it is defined in to the controller message transfer which period
Automatically the repetition time, its regulation controller should in which period transmission message
Begin to postpone, it is defined in first message of transmission after which of model start time
Time-out time, its regulation controller how long repeat the to lead to errors message of frame (for example because the affirmation of disappearance)
The functional block of the timing information with oneself of oneself is set in model for each message that will send in particular, in the prior art.In addition, can enough individual feature piece management multiple messages.
Also support request message and remote message in the prior art.From another bus user request message, the sign of the message of being asked realizes by message identifier by request message.Remote message is the auto answer of controller for request message.
Multiple bus can be connected to each other by other functional block, and by on a bus, receive message and on another bus, send again and between two or more networks pass-along message.
Some functional blocks are set to handle the message that is suitable for standardized agreement.Other functional block is handled raw data, and makes it possible to set up other agreement and pass through these functional blocks uses in model.
Can read in for example configuration file of DBC, MAT, FIBEX or LDF form for being configured.
In order to check the correct transmission of message, CRC check often is feasible.This verification also can be undertaken by the distinctive code of user.
By means of behavior model and the distinctive configuration of simulation hardware and disposed, definition externally measures or generates and so on the I/O function in the input and output of equipment (for example opertaing device that will test), set up executable program, be so-called real-time application, this program should be carried out on simulation hardware.
The I/O function is particularly set up and disposed to application of the present invention, mate with simulation hardware and set up real-time application.
Background technology
So-called real-time interface (RTI) is used for for example using MathWorks
The behavior model of setting up and the prior art of the interface between the simulation hardware (also seeing also dSPACE catalogue 1999-2000).It is for Real-Time
And Stateflow
(C code generator) carried out the automatic realization that expansion makes it possible to be implemented in Simulink model and Stateflow model on the simulation hardware.
In order to connect behavior model and actual external environment condition, in the behavior model, need the suitable input quantity that is used for model or the interface of output quantity.As such input/output interface, the functional block of graphics mode is set in the prior art, and it is configured according to the I/O function of hope.
In order to dispose I/O, for example there is the functional block storehouse of comprehensive graphics mode available with graphics mode.This storehouse for example comprises can be by the information of hardware use.For behavior model and being connected of input/output cards are carried out modeling, can from the functional block storehouse of graphics mode, select corresponding I/O functional block or corresponding I/O functional block model, so that can add corresponding expression to behavior model.There is oneself a storehouse in the prior art for each type of hardware, makes the interface of determining this type of hardware by the functional block of from a storehouse, selecting graphics mode, and only can be with corresponding cost another functional block replacement with another type.
All settings, for example parametrization can be carried out in the input template (Eingabemaske) of corresponding graphing capability piece.Here can check the validity of input.
But the shortcoming of prior art is that the behavior model that has the distinctive configuration of hardware mixes with the foundation of I/O function.This causes is that the change or the change of simulation hardware of behavior model all can cause the very big change of expense.Testing another behavior model or identical behavior model with identical I/O function is used in and is not easy to possibility on the different simulation hardwares.
RTI supports aperiodic incident, for example Wai Bu hardware interrupts and software interruption, and the user can be carried out to Task Distribution priority for the subsystem that is triggered by interrupt request.
For the system of each type, for example the time is continuous, time-discrete, mixing and multirate system, provides the piece of graphing capability separately for it in the prior art.According to I/O hardware, the different hardware resource of or different input/output cards can different sampling rates be used, and can be used in different subsystems under the possible situation.Here the user also must understand the simulation hardware of execution when setting up interface configuration.
Even for example before producing the real-time application will download on the simulation hardware or during should carry out compatibility (Konsistenz) checking, simulation hardware also must be known.
In addition advantageously, As be well known in the art, when producing code, optimize this code at executed in real time.
In order on simulation hardware, optimally to carry out real-time application, importantly can carry out some task configurations.Prior art provides multiple choices for this reason.
For example, support that multirate system and also supporting thus interrupts, based on the multitask of priority.In addition, single task of timer pattern and many task of timer pattern and non-based on real-time simulation model are arranged.Interrupt request can be for example by external hardware or excite by software in addition.Exist configurable overrunning (Overrun) to handle for each task.In addition, can measure for each task creation turnaround time (Turnaround-time).Optionally, can have a high regard for the definition external event of being engaged in for driving timing.
So in the prior art, real-time application can especially automatically be downloaded on the concrete simulation hardware and can execution model.Wherein instrument can be carried out mutual control, supervision and data acquisition by experiment.
A kind of RTI expansion that is used for multicomputer system or multi-core processor: RTI-MP is arranged in addition.This expansion is used to multiprocessor or many inner cores to carry out the setting of graphics mode.By each processor or kernel are carried out the performance that independent parameter adjustment should reach optimization.So the user can be for example for each subsystem be provided with independent performance optimization in RTI-MP, for example step-length, integral algorithm and trigger condition.These settings also can be depended on processor or kernel respectively, and feasible different processors or kernel for same multiprocessor or many kernels system has different settings.This point is paid attention in inter-processor communication.Interrupt request between processor or the kernel is fully supported.RTI-MP also is responsible for making the tasks synchronization starting on processor or the kernel.
For parallelization, answering system is divided, and make to realize optimum processor load or kernel load and is between processor/interior internuclear communication definitions passage.For example, the user can use simple drag-and-drop function to give the part of processor or kernel apportion model.
RTI-MP also is provided as between real-time simulation and processor/and interior internuclear communication produces the possibility of optimized code.
For this reason, concrete hardware also must be known before configuration.To be embedded into behavior model because be used for disposing the functional block of simulation hardware, so before configuration, must carry out modeling to behavior model.Can not carry out the replacement of behavior model at this.
Equally, also can not be under the identical situation of I/O function with hardware of hardware replacement of another type, because the configuration feature piece is designed and configuration is specifically designed to a kind of simulation hardware.Thus, the foundation of whole real-time application is very dumb.

Yet must understand according to I/O model (111) to dispose which hardware resource (144,145,146) for this reason.Must be mapped to I/O function (114) on one or more hardware resource (144,145,146) for this reason.For this reason, instrument (110) has hardware topology (148), so that can represent (118) for each I/O function (114) is provided with one or more hardware resource, and the corresponding hardware resource type (144,145,146) of its performance hardware topology.
Hardware topology (148) comprises the information about specific hardware system (140).These information both can relate to the information about the structure of the element of hardware system (140), also can relate to the information about the communication of the element of hardware system (140).Information about structure is for example can use which hardware resource on which card on which unit in which groove.The communication information for example relate to card each other be electrically connected and a hardware resource with which I/O connector (154) is connected.Hardware topology (148) can be for example produces in instrument (110), can import or read in an existing hardware topology, perhaps can be automatically from the hardware scanning hardware topology of connection.
In addition, instrument (110) can calculate, shows and store the information (215) about external cable bundle (150).This information (215) for example comprises the I/O connector (154) of hardware in real time should be how and pin (153) physical connection of external unit.By the inside cable bundle in the emulator, the I/O connector is connected with the hardware resource of card.About the information (215) of external cable bundle (150) can illustrate equally external unit, for example opertaing device should be how with another external unit, for example another opertaing device or external loading are electrically connected.
Information (215) about bunch of cables (150) can be calculated from instrument (110), perhaps also can be loaded in the instrument (110), so that can use the connection that has existed in the I/O model (111).
Preferably, equipment interface represents that (113) are mapped on the I/O function (114) in I/O model (111), I/O function (114) is assigned to the model interface (123) of behavior model (121), and I/O function (114) is assigned to hardware resource (144,145,146) afterwards, carries out the calculating about the information (215) of external cable bundle (150).
B. example
The following describes an example in an exemplary instrument (110), setting up and dispose I/O model (111).But instrument (110) is not limited to this embodiment, and on the contrary, other embodiment also is possible.
I/O model (111) is described the complete chain from the signal of external unit (130) to the model interface (123) of behavior model (121).A chain like this can for example be made up of three parts, as shown in Figure 3.The element of this three part is represented with the graphing capability piece and in three row in example.Here, a functional block or be the expression that equipment interface is represented (113), I/O function (114), or be that the model interface is represented (112).But other performance (for example using form) of each of this part and element thereof also is fine.
Two expressions, for example equipment interface representative (113) and I/O function (114) or I/O function (114) and model interface represent the distribution between (112) can be for example by stroke graphics mode connection or also can for example in tabular drawing, be undertaken by drag and drop (drag-and-drop).
One row for example comprise represents (113) by all equipment interfaces of an emulator (140) use in emulation in an I/O model (111) and therefore.One preferred embodiment in, the information that is provided with about the level of equipment interface shows by block diagram (333).Equipment interface represents that (113) represent the similar pin (153) of one or more external unit (130) and comprise details about the input and output signal of this equipment.
Here, external unit (130) has type, and thus, equipment interface (133) and equipment interface thereof represent also to have type.For example, be used for should be at the tested control electronics of hardware-in-loop simulation (Hardware-in-the-Loop-Simulation) for the opertaing device type.Relative therewith, loadtype is used for and is connected an external loading on the opertaing device by emulator (140).Such load can be the actual loading (for example actuator) or the equivalent load of the electrical specification of artificial actual load only.According to its type, equipment interface represents that (113) have different characteristics.By means of these characteristics, the user can be supported when being provided with and dispose I/O function (114).
In addition, represent (113), especially allow to carry out or disengagement failure emulation, and describe which kind of fault type of permission in detail for each equipment interface.Equipment interface is represented these settings of (113) and may be also had characteristic can be transferred in the expression that is assigned with of I/O function (114).
Also can for example specify the load of the joint (153) that is used for external loading to cut off.The load cut-out means cuts off load during fault simulation, so that the sensitive load of protection.
Other characteristics of equipment interface (133) are about what uses the information of this equipment interface (133) for, and for example pin is the input pin pin of signal (that is should produce thereon) or output pin (that is the pin of measured value) thereon or bus or low reference pin or undefined pin.For example, can represent at equipment interface differently to represent these information with graphics mode in the graphic presentation of (113).
In addition, can specify pin numbering arbitrarily in equipment interface (133), it is considered when the information of calculating about external cable bundle (150) (215).
Configuration data that can storage device interface (133) is so that reuse it in another I/O model (111) in same instrument (110).If the characteristic changing of equipment interface (133), then the characteristic of the expression (113) of this equipment interface (133) also changes.
