1. Platform Introduction The
Medical Electronic Automation Design Tr*ning Platform is based on Xilinx's Spartan3E-XC3S250E experimental teaching platform. This product is m*nly *med at senior undergraduates and postgraduates majoring in biomedical engineering, electronics, computer science, etc.
The experimental platform can complete routine human physiological parameter monitoring, such as electrocardiogram, blood oxygen, body temperature, respiration, non-invasive blood pressure and invasive blood pressure. In addition, the experimental platform also includes a wealth of peripherals, including a 7-inch 800*480 resolution touch screen, OLED12864 display module, LCD1602 display module, seven-segment digital tube, independent buttons, LED, matrix keyboard, and dial switch.
Since the platform is integrated with a Bluetooth module, students can develop some APPs based on Android phones and interact with various modules on the platform, which is convenient for the development of home and portable medical devices.
The human physiological parameter monitoring system that comes with the medical electronic automation design tr*ning platform can be used to monitor the five major human physiological parameters: electrocardiogram, blood oxygen, body temperature, blood pressure and respiration. The monitoring system is connected to the medical electronic automation design tr*ning platform through an expansion board. Since the expansion board is open, more expansion boards can be made later.

7. Virtual simulation software for mechanical tr*ning safety education: This software is developed based on unity3d. The software adopts the form of 3D roaming. The movement can be controlled by the keyboard and the direction of the camera can be controlled by the mouse. There are mechanical safety distance experiments, mechanical safety protection device experiments, and basic assessments of mechanical safety protection design. During the experiment, the 3D roaming screen uses arrows and footprints to prompt movement 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 3D 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 reminders are received. Mechanical injury, and then 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.
