An overview,

"Nakedness JXSM - 2 d digital electronic technology experiment platform" is combined with the current development trend of electronic technology experiment, experiment box maintenance for aluminum alloy, easy to go bad, process the general characteristics, research and development of new electronic technology experiment box, can finish the virtual simulation electronic technology, virtual instrument using now for the development of electronic technology, the modular design, the new design at the same time the regulated power supply, all digital design, greatly improves the reliability and efficiency.

Technology configuration

* 1. The experimental platform is designed with a full range of molds and has a beautiful appearance. It is made of high-quality PVC and black engineering plastics. Leave virtual oscilloscope, virtual signal source interface, power interface, I/O interface and other common interfaces. Each bin can hold four modules at once.

The 2 modules are made of 2mm thick printed circuit board, with the graphic symbols of components and corresponding wiring printed on the front and the printed circuit printed on the back, and the related components and so on welded. Easy maintenance. High quality galvanized pole can be used to complete circuit power supply.

3. The experiment box shall be equipped with voltage regulator power supply required for the experiment. Voltage regulator power supply (configuration shall not be less than ±5V/ 0.5a, ±12V/ 0.5a and voltage adjustment range 0 ~ 18V/1A;) , all digital design, with communication interface and full network data monitoring function, provide cloud tools such as LABVIEW and mobile APP software, with short circuit protection and automatic recovery.

4. Digital circuit module 4 piece, one piece of CPLD as the basic module design, set up a single pulse and continuous pulse, digital tube circuit, serial port function, with other modules can realize virtual operating and experiment, the other three pieces of module on the basis of practice, each configuration of 5 chips 16 feet (3 of 14 feet, 2) the definition of each chip can choose according to experiments need to be sure, don't need the actual chip, configuration choice using a 4.3 -inch LCD touch screen.

5. Provide experimental instruction and other teaching resources. The wires have different colors.
