Design of Micro-oxidation power control system based on LPC2119
MAO (micro-oxidation) is a surface process technique which makes ceram layer grows in the original position of the surface of metal. A self-developed micro-oxidation power control system was introduced in this paper. The hardware part composed of low consumption 32-bit microcontroller LPC2119 developed by Philips Company instead of MSC 51 single chip, which enhanced the stability and extensibility of system; while the software design adopted uC /OS-Ⅱ multitask type instead of the traditional forward and backward design type, which enhanced the precision and real-time response of the system. Parameters can be set the same as PC, and preset functions can also realized in this system. We have used the PID control way in the sysytem.. In addition, large scale adjustment of voltage, current, pulse frequency and duty ratio can also be satisfied. The developed system has been applied in products, leading to well effects.
