As data transmission and processing mode in traditional laser marking control system have the redundant and complex hardware constitution,a solution scheme based on embedded system was proposed. The control mode change of the whole laser engraving production was achieved by changing the way of data transmission,so that laser marking don’t require the industrial computer and the control software,moreover,it can realize online and offline engraving,etc. The receiving and transmission of the data are realized by the embedded Ethernet based on MCU and RTL8019AS,and the concurrent control of the laser generator and galvanometer scanning is implemented through the time-sharing of the microcontroller I/O ports. In this scheme,the needed marking data are transmitted through TCP network,and then these received characters are transformed into laser dot matrix control data by marking algorithms,and finally,the dot matrix scanning laser marking is realized. The results show that the system has good robustness and high marking speed.
