Medical electronic automation design experiment table

Medical electronic automation design tr--ning platform is based on Xilinx's Spartan3e-XC3S250E experimental teaching platform. This product is m--nly for high-grade undergraduates and graduate students in school biomedical engineering, electronics, and computers.

This experimental platform can complete conventional human physiological parameters monitoring, such as ECG, blood oxygen, body temperature, breathing, non -invasive blood pressure and blood pressure. In addition, the experimental platform also includes rich peripherals, including 7 -inch 800*480 resolution touch screen, OLED12864 display module, LCD1602 display module, seven -segment digital tube, independent keys, LED, matrix keyboard, dial switch, etc. Essence

Because the Bluetooth module is integrated on the platform, students can develop some APP based on Android mobile phones to interact with various modules on the platform to facilitate home and portable medical equipment development.

Medical electronic automation design tr--ning platform supporting human physiological parameter monitoring systems can be used to monitor 5 major human physiological parameters of ECG, blood oxygen, body temperature, blood pressure, and respiratory. Because the extension is open, more expansion boards can be made in the future.

7. Mechanical tr--ning Safety Education Virtual Simulation Software: This software is developed based on Unity3D. The software uses the form of three -dimensional roaming. It can control the movement through the keyboard. Basic assessment of the protection design. During the experiment, 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. The experimental process is accompanied by a three -dimensional robot dialog box reminder.

4. Tr--ning device Standard Size: 1500mm × 650mm × 1700mm

2. M--n features

1. It is m--nly composed of components such as tr--ning tables, tr--ning desks, pneumatic components, and electrical control devices.

2. The tr--ning table and tr--ning desk are iron double -layer sub -light -dense -densely spraying structures, and hydraulic components are stored in the tr--ning table drawer.

3. Equipped with commonly used pneumatic components for industrial, and all equipped with transition bottom plates, which can be convenient and randomly inserted on the tr--ning table panel (the panel with the "T" groove -in -form aluminum alloy profile structure). The loop overlap is fast -changing, which is convenient and fast for disassembly.

4. The pressure of the gas source is low, and the electrical control uses a low voltage DC 24V power supply; the tr--ning gas road, the control circuit are safe and reliable, and have control functions such as manual, automatic, and order.

5. The tr--ning control unit adopts an independent relay control unit for electrical control.

6. Hydraulic --r pressure transmission design and control virtual simulation software

 

This software is based on Unity3D. The software adopts the form of three -dimensional roaming. It can control the movement through the keyboard. The mouse controls the lens direction. The interface is equipped with homepage, help, full -screen, component cognition, circuit construction, key component testing, and typical system test interface.

1. Component recognition uses the form of automatic playback, which introduces the em--l, liquid level meter, and oil pump unit on the device (here is the introduction of the pop -up hydraulic symbol, principle and introduction, click OK to enter the next introduction), valve frame, pressure gauge table), valve frame, pressure gauge table , Sensor, etc.
