SUMMERY OF THE UTILITY MODEL

Not enough to exist among the prior art, the utility model provides a singlechip system teaching support convenient to function show of singlechip does benefit to the study of modelling.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

a single chip microcomputer system teaching support comprises a support rod, a bottom plate and a support plate; one end of the support rod is vertically fixed on the bottom plate, and the other end of the support rod is vertically and fixedly connected with the support plate; the bottom plate and the support plate are both rectangular structures, and the area of the support plate is smaller than that of the bottom plate; a plurality of semi-through holes or through holes are arranged on the carrier plate; and a circular groove is arranged on the bottom plate and on the surface connected with the support rod.

When the utility model is used for function display, a plurality of single chip system boards with different sizes, battery boxes, sensor modules of different types and auxiliary test equipment, such as reflectors, color blocks, motor fixing seats and the like can be installed and fixed by utilizing the half through holes or the through holes on the support plate, so as to realize the display of different functions of light path calculation or distance measurement, color discrimination, motor driving and the like; in combination with the groove on the bottom plate, auxiliary test equipment such as a water cup can be placed for carrying out function display of liquid level height measurement and pH value test; due to the convenience in installation, fixation and replacement, the singlechip system and/or the sensor module can be rapidly replaced in a short time, and the experimental equipment does not need to be connected and fixed by using double-sided adhesive or other fixing devices in a time-wasting manner;

when the utility model is used for modeling and learning, the circular groove can be used for area measurement and volume measurement, and the support plate and the bottom plate are used for height measurement; the sideline measurement and the volume calculation of a preset eccentric cone or oblique cone can be realized by combining the support rod and the circular groove; because whole device structure is fixed, the short patchcord of convenient use length connects singlechip system board and sensing unit or other experimental part in the installation, and is clean and graceful.

Compared with the prior art, the utility model discloses following beneficial effect has: the single-chip microcomputer system board and the experimental device can be conveniently plugged, a simulation experiment scene can be quickly built, function display is facilitated, single teaching of book knowledge is changed to solving of actual problems, and the capability of analyzing and processing problems is improved.
