The K-line host computer application software comprises the following functions: serial communication, KWP2000 protocol testing, K-line fault diagnosis, data flows, executor testing and Flash programming.
Description
Technical field
The present invention relates to a kind of ECU debugging software especially based on the debugging software of the PC of K line and WP2000 agreement end.
Background technology
ECU(Electronic Control Unit) electronic control unit claims " car running computer ", " vehicle-mounted computer " etc. again.From purposes then is the automobile specified microcomputerized controller, also is the automobile specified single-chip microcomputer.It is the same with common single-chip microcomputer, is made up of large scale integrated circuits such as microprocessor (CPU), storer (ROM,, RAM), input/output interface (I/O), analog to digital converter (A/D) and shaping, drivings.The function of ECU (Electrical Control Unit) is to carry out computing, processing, judgement according to the information that the program of its internal memory and data are taken into account various sensors inputs to air mass flow, output order then, and the electric impulse signal that certain width is provided to fuel injector is with the control distributive value.ECU (Electrical Control Unit) is made up of microcomputer, input, output and control circuit etc.
Engine ECU requires to have the OBD(onboard diagnostic system) record trouble generation information and time, each fault all has the diagnostic trouble code of standard on international standard, find diagnostic trouble code to be stored on the flash storer of ECU, need a fault diagnosis terminal, can keep in repair by the failure diagnostic apparatus Read fault, failure diagnostic apparatus and ECU connecting line are exactly the K line.The serial ports of K line on automotive electronics is SCI, and process K line conversion chip is MC33290.
The KWP2000 private communication protocol is that comparatively general serial communication protocol is used in present automobile failure diagnosis field, help the further exploitation of product, and have extremely strong versatility, guarantee that the electric-control system of exploitation can mate with vehicle motor and realize to produce in batches better.KWP2000 serial communication international standard (ISO/wD14230) is used to define the general requirement of the diagnostic system that connects based on serial data.It defers to IS07498 according to the basic reference model of open system interconnection (O.S.I), and its structure can resolve to the communication system of 7 sublayers.In the time of on being mapped to this model, the employed service of ECU can be divided into: Diagnosis Service (the 7th layer) and communication service (the 1st to the 6th layer).The ISO7498 international standard has been formulated the requirement of KWP2000 data link in detail, and this link is by with one or several being connected to finish diagnostic function with car electronic control unit and an off-line diagnostic equipment.KWP2000 comprises three parts: Physical layer; Data link layer, fault processing; The realization of Diagnosis Service (task layer).2.1 this part has described Physical layer based on ISO 9141, in order to realize the Physical layer of Diagnosis Service.It is according to the physical layer specifies of describing in IS0914l_2, but is extended to the clause that can satisfy the vehicle that 12V or 24V voltage are provided.2.2 this part has described master data link composition, data frame structure of communication protocol etc. data link layer, this Diagnosis Service allows a diagnostic equipment with the car electronic control unit (for example to be controlled at one, Electronic Fuel Injection (EFI), automatic gear-box, anti-lock braking system ...) in diagnostic function.These link together by serial data link with the car electronic control unit.
Summary of the invention
The objective of the invention is, a kind of 32 ECU platform K line host computer application software are provided, based on DELPHI design configuration user interface, be used to realize with 32 ECU platforms based on the communication of KWP2000 agreement and failure diagnostic apparatus basic function (comprising reading of diagnostic trouble code, data stream, freezing data frame), finish the K sequence of threads simultaneously and write with a brush dipped in Chinese ink function.
The function that K line host computer application software comprises: serial communication, KWP2000 protocol test, K line fault diagnosis, data stream, actuator test, Flash programming.
(1) serial communication has been realized the serial communication general utility functions, and serial ports attributes commonly used such as port, baud rate can be set, and carries out the universal serial port communication.In addition,, increase with 32 ECU and set up communication function, set up being connected of K line communication with ECU at project characteristic.
(2) the KWP2000 protocol test is primarily aimed at K line communication function and designs, and can realize communication with ECU according to the communication modes of KWP2000 agreement regulation.
(3) K line fault diagnosis is used to realize the fault diagnosis basic function, reads and analyze the ECU diagnostic trouble code, gives the relevant information that is out of order, the emulation car failure diagnostic apparatus.
(4) data stream is used to show Kwp2000 protocol specifies data stream, is used for the fast monitored of the central related data of ECU operation.
(5) the actuator test is used for the test of ECU associated actuator, emulation car failure diagnostic apparatus corresponding function.
(6) the Flash programming is used for K line Flash programming, realizes that Flash wipes, programming common functions such as Blank Check, Verify.
Description of drawings
Fig. 1 software function implementation.
Embodiment
Each function of software realizes at first triggering by message circulation, button as shown in Figure 1, starts timer timed sending data then, sends the back that finishes and receives data, last deal with data.In the serial communication general utility functions, by port button, baud rate button etc. are set, carry out the universal serial port communication, and increase to resolve and open the news button, disconnect K line communication with 32 ECU.P2, P4 and KWP2000 protocol command manually are set, different delay parameters can be set, carry out the communication test of K line KWP2000 agreement flexibly with ECU.In K line fault diagnosis panel, read the DTC(diagnostic trouble code by button) and carry out correlation analysis, Clear DTC (removing diagnostic trouble code) button is removed the DTC of ECU.Read FreezeData(reads the freezing data frame) read the freezing data frame that is stored in the ECU, and show relevant information, and Clear FreezeData(removes the freezing data frame) clear related display content.Begin image data stream by the Start button in the data stream function, constantly refresh demonstration, the Stop button stops data acquisition, and ClearList removes display list.When in the Flash programing function, programming, at first Erase wipes the FLASH of ECU, ECU enters programming mode, whether Blank Check button detects FLASH is empty, the Browse button is selected to write with a brush dipped in Chinese ink the run time version file, click the Program button and begin coding, after programming is finished, can click Verify button check programmed result.
