Laser marking is a mark on the international industrial products , one of the most state-of-the-art technology has increasingly become an efficient marker processing method . Laser marking machine is a combination of laser , optics , computer , precision machinery and technologies such as an electromechanical integration equipment , it mainly consists of lasers , optical systems and controllers . The PCI bus is a high-performance 32 / 64 address data multiplexed local bus , it has a data capacity of the ISA bus can not be achieved , the advantages of high speed . The completed computer control mode control card PCI bus - based laser marking systems design . Based on careful analysis of the working principle of laser marking machine , marking control card for the PCI bus - based laser in-depth study and design of a PCI bus - based laser marking control card . In this paper, the PCI9052 direct data transmission mode , the completion of the data transmission . Control chip MCX312 use of counter 8254 to be discussed. And the method of preparation of the driver .
