Abstract
The present invention provides a development method of an automobile decoder system, the method includes the design of an automobile computer decoder system platform, a data flow processing function, a fault code processing function, and the like; in the bottom layer design of the system, the callback function processing technology is adopted. The technology provides an effective channel for calling application function of a decoder bottom layer system, thereby extending the function of the decoder bottom layer system and ensuring the scalability and flexibility thereof. The bottom system developers can not completely predict the data flow processing approach, but needs to decide the program flow direction of the bottom layer system according to each data flow processing result when developing the operation system. The bottom layer system reserves an import address and some variables needing to be inputted for the callback function. The research and development personnel only need to compile corresponding processing function aiming at each data flow item of the present specific automobile models and assign value to the corresponding suction parameters, the needed functions can be realized.
Description
Technical field
The present invention relates to a kind of development approach of automobile decoder system
Background technology
The development approach of automobile decoder system, generate the travel condition of vehicle data by decoding, these data are compared with corresponding standard data in the travel condition of vehicle standard database (data area under the normal condition), just can judge vehicle and whether move normal and concrete fault.Under prior art, these data what relatively adopt is enumeration method, and the present invention's employing is to reserve corresponding function when system bottom is developed, can carry out redirect according to the function of reserving when detecting corresponding data stream searches, improve the travelling speed of system, made things convenient for the end user to consult relevant data stream faster.
Summary of the invention
For overcoming the above-mentioned defective of prior art, the invention provides a kind of development approach method of automobile decoder system, adopt this method, can make the developer needn't worry that the software of being developed can't write decoder system fast.
The present invention realizes that the technical scheme of above-mentioned purpose is: a kind of development approach of automobile decoder system is reserved function interface when system development, carries out redirect and search when searching function.
Description of drawings
Accompanying drawing is a simple and easy process flow diagram of the present invention.
Embodiment
Referring to accompanying drawing, the development approach of automobile decoder system provided by the invention.
The workflow of described demoder is:
(1) developer writes various vehicle communications protocol;
(2), write and reserve inlet in the decoder system with the communications protocol of vehicle;
(3) have living space as reserving inlet in the decoder system, then can normally write;
(4) do not have the space as reserving inlet in the decoder system, then the decoder system call back function can locate and search the reservation inlet that has living space and corresponding protocol is write this inlet.
Claims (3)
1. the development approach of an automobile decoder system is characterized in that the design of automobile computer decoder system, when design system, for the software of following program staff development is reserved with certain entry address and some variablees that need import.
2. the call back function disposal route of automobile decoder first floor system as claimed in claim 1 adopts when it is characterized in that the system bottom exploitation when reserving function work readjustment in future and uses.
3. the disposal route of first floor system call back function as claimed in claim 2 is characterized in that workflow is:
(1) software developer writes the communications protocol of vehicle, and this agreement and automobile decoder system are linked;
(2) leave the corresponding inlet of 1-N in the decoder system:
(3) attempt the corresponding inlet of decoder system is write fashionable when communications protocol, judge at first whether this inlet has living space;
(4) as this inlet corresponding space is arranged, then this agreement can write this reservation inlet.
(5) do not have corresponding space as this inlet, then this agreement attempts to carry out next the writing of inlet of reserving, and allows writing of this agreement up to there being a reservation inlet to have living space.
