Remote Controllable CNC Power Design

摘要

This paper used ATMega8L as the core controller, achieved the functions such as preset keyboard, the step adjustment with coarse adjustment and fine-tuning coordination and LCD liquid crystal synchronize display voltage preset value and the communication with PC. The output voltage range is 0-15V, the maximum output current is 1A, the step value is 0.1V. The system has advantages of reliable, simple operation, high control precision, practical and widely used and so on. Not only insure the perfect inner performance, but also has diverse and specific external characteristics and the external interface, which determines such kinds of power system has the eclectic essence of many disciplines, and has advantages of simple operation, low cost, can be remote control through the network, and can be applied to many occasions.
