Comprehensive experimental device of single -chip microcomputer development and application technology

 

This device consists of control screens, experimental hanging, and experimental tables. Through the experiment of the interface expansion, data acquisition, data display, keyboard control, and timer of the single -chip microcomputer through this experiment, it can be equipped with an emulator.

 

There is a current leakage protector. If there is a leakage in the control screen, the leakage current exceeds a cert--n value, that is, cutting off the power supply, which will protect personal safety.

 

The device adopts a component structure to replace the experimental module convenient. If you need to expand the function or develop new experiments, you only need to add an experimental module hanging box, and never eliminate it.

4. Virtual simulation teaching system

 

Machinery tr--ning security education virtual simulation software: This software is developed based on UNITY3D. The software is in the form of three -dimensional roaming. It can be moved by keyboard control. The direction of the mouse control lens is equipped with mechanical safety distance experiments, mechanical safety protection device experiments, mechanical safety protection design Basic assessment and experiments, the three -dimensional roaming screen uses arrows and footprint patterns to move to the experimental location. The circle around the mechanical object shows a working radius, and the experimental process is accompanied by a three -dimensional robot dialog box reminder.

A. Mechanical safety distance experiment content includes a safe distance experiment to prevent the upper and lower limbs from touching the dangerous area (the height and opening of the two fences in the inside). After choosing to enter, the GB23821-2009 "Mechanical Security to prevent the upper and lower limbs from touching the dangerous area of the dangerous area. "Safety distance" requires that the error demonstration: After the experimental process is harmed by the working radius of the human body entering the mechanical object, the blood -colored picture and voice reminder receive mechanical damage, return to the original position and perform the next experiment. The final step is the correct practice.
