Based on these platforms, students can quickly master various practical skills, such as medical electronic instrument design skills, microcontroller programming skills, object-oriented programming skills based on C++, object-oriented programming skills based on Java, object-oriented programming skills based on C#, hardware circuit design skills, etc.
This experimental platform can not only complete the basic experiments of single-chip microcomputers, such as the design experiment of running lights, independent button experiments, matrix keyboard scanning experiments, seven-segment digital tube display experiments, touch screen experiments, LCD screen display experiments, voice broadcast experiments, serial communication experiments, Bluetooth module communication experiments, Wifi module communication experiments, DC steering gear experiments, AC motor experiments, touch button experiments, but also complete medical electronics professional experiments, such as body temperature detection and display experiments, pulse wave detection and display experiments, blood pressure monitoring experiments, breathing monitoring experiments, ECG signal detection and display experiments.
The human physiological parameter monitoring system can also be used independently in object-oriented programming courses, such as "Object-oriented Programming Based on MFC", "Object-oriented Programming Based on Winform" and "Object-oriented Programming Based on Java". The experiments that can be carried out include body temperature detection and display experiments, pulse wave detection and display experiments, blood pressure monitoring experiments, breathing monitoring experiments, ECG signal detection and display experiments and monitor human-computer interaction experiments.

9. The monitoring platform can be independently applied in object-oriented programming courses, such as object-oriented programming based on MFC (C++), object-oriented programming based on Android (JAVA), and object-oriented programming based on Winform (C#);
10. The experimental platform is equipped with rich tutorials, handouts and videos;
11. This experiment can be applied to electronic related majors, such as electronic information engineering, communication engineering, automation, electromechanical, optoelectronics, biomedical engineering, etc., as well as software related majors, such as computer science and technology, software engineering, etc.
12. Virtual simulation software for mechanical tr*ning safety education: This software is developed based on unity3d. The software adopts the form of three-dimensional roaming, which can be controlled by keyboard movement and mouse control of lens direction. It has mechanical safety distance experiment, mechanical safety protection device experiment, and mechanical safety protection design basic assessment. During the experiment, the three-dimensional roaming screen uses arrows and footprints to prompt to move to the experimental position. The circle around the mechanical object shows the working radius. The experimental process is accompanied by a dialog box reminder of the three-dimensional robot.
A. The content of the mechanical safety distance experiment includes the safety distance experiment to prevent the upper and lower limbs from touching the dangerous area (divided into 2 types of fence heights and opening sizes). After choosing to enter, the GB23821-2009 "Safety Distance for Mechanical Safety to Prevent Upper and Lower Limbs from Touching Dangerous Areas" requirements pop up in front of the camera. Wrong demonstration: The experimental process is that after the human body enters the working radius of the mechanical object and is injured, the bloody screen and voice reminder receive mechanical injury, and return to the original position and conduct the next experiment. The final step is the correct approach.
B. Mechanical safety protection device experiments are divided into safety interlock switches, safety light curt*ns, safety mats, safety laser scanners and other protection device experiments. Optional categories (safety input, safety control, safety output, other), manufacturers, product lists (safety interlock switches, safety light curt*ns, safety mats, safety laser scanners, safety controllers, safety relays, safety fences). The installation location has a blue flashing frame reminder. The experimental process is: select the safety fence and install it, select the safety interlock switch (or select the safety light curt*n, safety mat, safety laser scanner) and install it, select the safety controller and install it to the electrical control box, select the safety relay and install it to the electrical control box, and click the start button on the electrical control box. If you enter the dangerous area, the system will prompt an alarm sound, and the mechanical object will stop working. Select the reset button on the electrical control box to stop.
C. The basic assessment of mechanical safety protection design requires the completion of the installation of the mechanical safety system, the correct installation of safety guardr*ls, safety interlock switches, safety light curt*ns, safety mats, safety laser scanners, safety controllers, safety relays, 24V power supplies, signal lights and emergency stop buttons. The assessment is divided into ten assessment points. Some assessment points have 3 options, which are freely selected by students. After the final 10 assessment points are selected, submit for confirmation, and the system automatically calculates the total score and the score of each assessment point.
D. The software must be on the same platform as a whole and must not be displayed as a separate resource.
E. At the same time, the VR installation package of this software is provided to customers to facilitate users to expand into VR experiments. VR equipment and software installation and debugging do not need to be provided.
