2. Brief introduction to the project

Intelligent CNC power supply

1. Trade war, in order to avoid imports Due to chip restrictions, domestic components are used, and the localization of components reaches 99%.

2. Promote "China Manufacturing 2025 (Industry 4.0)", accelerate the establishment of smart industry, establish mobile Internet and industrial production. The power supply supports remote network control, and the power supply can be controlled and monitored wherever there is a network signal.

3. Freedom, you can connect to the Internet through WIFI or network cable, install new applications online, update existing programs, or install applications written by yourself.

4. Multiple operation modes, integrating 5 human-computer interaction modes

(1). Button operation, operating the power supply through 5 navigation buttons + 2 function buttons.

(2). Touch operation, using a 3.5-inch large-size capacitive touch screen and display panel, with high operating sensitivity.

(3). Browser operation (intranet), after connecting the device through WiFi or network cable, open the computer or mobile browser to access the IP of the CNC power supply to open the operation interface.

(4). Remote control through the mobile app while connected to the Internet (external network).

(5). Remote control through computer under network (external network) status.

5. Multiple working modes, constant voltage mode (CV), constant current mode (CC), constant power mode (CP), circuit breaker mode (turn off the power output after exceeding the set current or set power, and then automatically recover after waiting x seconds , x can be set freely and is often used in industries such as mobile phone repair).

6. All-round protection, overvoltage protection, overcurrent protection, overpower protection, short circuit protection, backflow protection, and undervoltage protection.

7. Freely set voice prompt function.

----------------------------------

#### **Involves many aspects, including hardware development (3 PCBs schematic diagram and board drawing), structural development (the panel is 3D printed for proofing) Linux kernel development, driver development, QT application development, microcontroller development, the server backend is developed using NodeJS, and the front end involves Vue development. Alas, a rogue is alone during the day. I was at work and was too busy to work at night, so the project was delayed. The main interface (desktop) is developed using AWTK (Zhou Ligong GUI), the file system is compiled using buildroot, and the QT5 library is configured. **

#### **This project will be fully open source and will be continuously updated in the community for everyone to DIY. Interested partners are also welcome to participate in joint development. Work together to create an open source community environment. **![IMG_20200827_204759.jpg]
