Research And Development Of Embedded NC System Used On A PCB Drill

Embedded system is a kind of special application-oriented computer system. It is based on computer technology and can meet the strict requirement of function, reliability, cost, volume, and power consumption by adjusting its hardware and software . With rapid development of hardware technology and software technology of the computer, embedded-system technology is getting more reliable and perfect step by step. At present, embedded system has been widely used in many fields such as industrial control, traffic control, and etc, because of its high reliability, high performance, low power consumption and so on. The same time of, Printed Circuit Board(PCB) is an absolutely necessary part of modern electronic products, with the development of PCB technology, further needs are put forward to its manufacturing process and equipment. As the special equipment of PCB mechanical processing which is an important procedure of PCB manufacturing process。Combined with the project research and development of embedded NC system used on a PCB drill, and based on in-depth study on technology of embedded system, this dissertation chooses specific platform of hardware and software to research and develop the embedded NC system of milling machine. The kernel of hardware is the 32-bit embedded CPU LPC2210 with characteristics of high performance and low power consumption. And it is also equipped with the required peripheral modules to extend itself to one whole hardware system. The software is based on uC/OS-II real-time embedded operating system, and the required application software needs to be developed so as to turn uC/OS-II real-time embedded operating system into one practical embedded NC system of Drill machine, which not only has virtues of high reliability, high performance, but also can be transplanted and trimmed so well as to modify function conveniently according to system requirement.
