[Abstract]:The hardware industry is one of the important industries of our national economy. As one of the important members of the hardware industry, the lock processing industry is developing rapidly. Lock manufacturing equipment is the key of processing machinery lock, with advanced equipment to produce high-quality products. With the rapid development of the demand, it is obvious that the traditional manual dial-up code can not meet the requirements. With the continuous development of computer technology, electronic technology and machining technology, the tooth flower processing has changed from the traditional manual dial-up code to the computer automatic coding, digital control, so as to realize the high precision of the key tooth flower processing. High key rate, high efficiency. With the rapid development of embedded technology, embedded Linux system has been widely used in CNC system. The embedded system's hardware chip is continuously integrated, the integrated peripherals are more and more, the function is more and more powerful, make the processor's reliability and the application level more and more high, and the power consumption is also very low. All these make the embedded system adapt to the higher and higher requirements of the CNC system. It has great advantages in real-time running, shortening the development period of the CNC system, increasing the flexibility of the CNC system, and so on. The purpose of this paper is to design a control system which can realize the key pattern processing according to the coding data generated by the upper computer. This paper mainly includes the following parts. Firstly, this paper analyzes the background and significance of the research, the development status and trend of NC machining system at home and abroad, and also introduces some technologies in CNC system. Secondly, this paper mainly describes the implementation process of the whole system, which is divided into two aspects: hardware and software. The hardware platform is TQ2440 development board, and the schematic diagram of the peripheral equipment and its usage are introduced. The software includes the software of PC terminal and the system of lower computer, in which the software of upper computer mainly introduces the generation and screening algorithm of tooth flower coding, the method of database operation. In addition, it also introduces how to display in real time the graphics and teeth which are being processed by the lower computer system and the G code used. The construction process of the lower computer system is divided into U-boot, Linux kernel clipping, yaffs2 file system construction. And the design of the peripheral driver and the programming of the application program after the successful startup of the system. The peripheral driver includes the LED driver, the keystroke driver, Nand Flash driver, the serial port driver and the motor driver, etc. In the application program, the algorithm flow of drawing out the graph according to the tooth flower coding and converting it into G code is introduced. Finally, the whole system is tested, mainly testing the implementation process of each module of the system and whether the results reach the desired goal. At the end of the paper, all the work is summarized. This paper evaluates and analyzes some problems existing in the system, puts forward the perfection of the whole system, and looks forward to the future function of the system and its application prospect. It has been proved by practice that the design has basically realized the predefined function and achieved the expected design goal. The innovative application of the new technology to the actual production has certain social and practical significance.
