Description
Technical field
What the present invention relates to is experimental teaching field a kind of trap formula Digital Electronic Technique experimental box.
Background technology
In the evolution of higher education or high vocational and technical education, experimental teaching is indispensable important step in the whole teaching process, particularly cultivates high-quality talents and be unable to do without experimental teaching especially.The teaching aid of various difference in functionalitys and advanced teaching means are the important platforms of realizing training objective, and therefore, each colleges and universities of institute does not have the construction that thinks little of platform, and function advanced person's various teaching aids are developed, upgrade, bought to the dynamics that increases input.
In colleges and universities' natural sciences electrical type specialty, generally offer this subject of Fundamental Digital Electronic Technique, in whole teaching process, comprised two links of theory teaching and practical teaching, experimental teaching is an important ring of practical teaching.It is an inevitable choice that function advanced person's teaching aid is adopted in experimental teaching, the Digital Electronic Technique experimental box, and Digital Electronic Technique experiment bag is answered pregnant at this point and is given birth to.No matter being the Digital Electronic Technique experimental box, or Digital Electronic Technique experiment bag, all is traditional craft experiment have been carried out integrated, and modular design is tested to compare with traditional craft and improved conventional efficient and experiment success rate.
Each colleges and universities of institute mainly adopts the Digital Electronic Technique experimental box to finish the experiment of this subject now, the Digital Electronic Technique experimental box has no doubt improved the success ratio of conventional efficient and experiment, but have the following disadvantages: (one) existing Digital Electronic Technique experimental box, mainly be to insert integrated circuit (IC) chip and line by a face thin plate, plug is wasted time and energy, and plug of a specified duration make easily that the reed distortion causes loose contact in the face thin plate.(2) the integrated circuit (IC) chip pin jack is leaned on closely, is difficult for finding and searching in case draw the plug wire wrong plug.(3) integrated circuit (IC) chip is changed in frequent plug, easily causes the bending of integrated circuit (IC) chip pin, fractures.(4) line is not directly perceived, eye-catching, wastes time and energy in case the no result of experiment searches reason.
(5) each experiment all will be finished experiment and all will be checked quantity for the student allots integrated circuit (IC) chip.
Summary of the invention
One, Fa Ming purpose.
