Abstract


Traditional computer ISA bus or PCI bus based laser marking controller relies on the computer, because the computer is a multitasking system, which reduces the stability of the controller. Although based on single chip microcomputer of laser marking controller of low cost, reliable operation, but due to the limited storage capacity, slow speed, limited the scope of its application. In order to solve these two problems, analysis of the current general laser marking control ways and improve the quality of laser marking marking and the perspective of cost saving option for improved control structure based on computer digital signal processor DSP2812 as the control system architecture of this system. This article first to a laser target principle, laser marking technology development present situation, the composition of laser marking system, laser marking system common control mode are introduced. Then the overall design of laser marking controller hardware and illustrates in detail the circuit design of each function unit, and gives the function of each part of circuit, communication protocol and some software flow chart are given. The final test results of the control system are analyzed and proposed the improvement opinion.
