Description
Technical field
The invention belongs to teaching experiment equipment field, more specifically to a kind of SCM Based micro control system
Comprehensive training platform.
Background technology
The Machinery Design, Manufacturing and Automation of many universities, Electrical Engineering and Its Automation, automation, electronics science with
The bachelor degrees such as technology, Electronics and Information Engineering, communication engineering, computational science and technology are all opened up《Fundamentals of Mono-Chip Computers with should
With》、《Embedded system》Deng Hardware courses, this accords with the demands of the market, but, the most of realities supporting with these courses
Test what is carried out still on experimental box, this is far from being enough.Experiment is done on experimental box to have the disadvantage that：
(1) student is understood not enough the general structure of hardware system, and docking vocal imitation skill is related to seldom.Reality is done on experimental box
Test, mainly by line realization, student only need to be according to the step specified by guide book of experiment, a step for the structure of hardware system
One step the port wire that should be linked together in system is coupled together just can be thus to cause few
Life removes to study intensively the circuit theory diagrams of the system, not to mention goes to study the general principle of these interfaces connection institute foundation, and this
A little is all necessary to carrying out micro control system design and realizing.
(2) student understands not deep to the structure of software systems with program circuit, and it is not enough that program code writes ability training.
Tested on experimental box, in order that student can complete experiment within the limited time, the success rate of experiment is improved, for certain
Micro control system, guide book of experiment typically all provides the program code corresponding with hardware system, and student only need to be in Keil C etc.
Compiling, debugging on program compiling platform, operation program just can be with.Under this experiment method, student oneself will not typically move
Brains write program code, let alone actively improve the Software for Design ability based on hardware system.
(3) student lacks overall understanding to the concept of system.Because hardware system and software systems can depend on him
People, therefore, student there is no need to go to think deeply the overall structure of micro control system from macroscopic perspective, also there is no need from microcosmic angle
Remove the local detail of further investigation micro control system.So, they are impossible to intactly to set up micro control system
Concept.
In a word, tested on experimental box, what student was done simply repeats the experimentation that others had done, and to micro-
Control System Design is short in understanding with the whole process for making, and cannot effectively be forged in terms of micro control system design with realization
Refining, although student finally sees expected experimental result, but, their results are in fact and little.If allowing themselves
A micro control system is designed and realizes, they are bound to be at one's wits' end, have no way of doing it.
It is applicant's understanding that《Single chip microcomputer》、《Embedded system》In etc. hardware based course, it should allow
Contact material object more student, operate in person, learned knowledge is firmly grasped on the basis of practice, improve manipulative ability.Particularly
《Single chip microcomputer》The experiment of course, it should encourage, instruct every student to do a mini system.By such instruction
Practice, student not only with the function of profound understanding single chip microcomputer internal part, and can in actual applications utilize the language that collects
Speech or C language carry out programming, can also really set up the concept of micro control system.And in the experiment based on experimental box,
These targets can not possibly reach.
Existing in order to overcome the shortcomings of to be tested on experimental box, we design and have made based on 51 series monolithics
Micro control system comprehensive training platform.
