【摘要】：半导体激光器具有体积小、工作寿命长、结构紧凑、转换效率高、稳定性高、通过电源直接调制光输出等一系列优点。使得它在光电领域受到广泛的关注,并成为目前固体激光器的主要发展方向,并在包括军工、通信、材料加工、医疗等一系列领域里得到广泛应用。伴随着控制技术的发展,自动化控制在各个领域受到广泛应用。而随着大功率半导体激光器技术的飞速发展,使得激光系统的架构更加复杂。因此,需要设计一个专门的控制系统来实现激光系统各功能模块的集成控制。本文通过对大功率激光器系统受控对象的分析,以及对整个控制目标的理解,设计了基于NI CompactRIO实时控制器的大功率激光远程控制系统。控制系统充分发挥了虚拟仪器的优势,利用R1O机箱能快速访问底层资源的特性对同步信号发生器进行了设计和优化,通过LabVIEW程序的数据流并行处理机制实现了发生、接收、处理的同步运行。控制系统由PC端和RT端组成,两者间用以太网进行通信。PC端主要用于人机界面的显示与指令发送。RT端主要用于被控对象的控制,以及提供脉冲恒流电源所需的同步信号。本文的主要工作包括：课题背景、设计方案的制定、控制器选型、控制系统的硬件设计、控制系统软件架构设计、控制系统各功能模块子程序设计、上位机与实时控制器间通信协议的设计。
[Abstract]:Semiconductor lasers have a series of advantages, such as small size, long working life, compact structure, high conversion efficiency, high stability, direct modulation of light output through power supply and so on. And has become the main development direction of solid-state lasers, and has been widely used in a series of fields, including military industry, communication, material processing, medical treatment, etc. With the development of control technology, Automatic control is widely used in various fields. With the rapid development of high power semiconductor laser technology, the architecture of laser system becomes more complex. It is necessary to design a special control system to realize the integrated control of each functional module of the laser system. A high power laser remote control system based on NI CompactRIO real-time controller is designed. The control system gives full play to the advantages of virtual instrument. The synchronous signal generator is designed and optimized by using R10O chassis which can quickly access the underlying resources. The data stream parallel processing mechanism of LabVIEW program is used to realize the synchronous operation of generating, receiving and processing. The control system is composed of PC and RT. The communication between them is mainly used in the display of man-machine interface and instruction sending. RT terminal is mainly used to control the controlled object and to provide the synchronous signal for pulse constant current power supply. The main work of this paper is as follows: background. Design scheme, controller selection, control system hardware design, control system software architecture design, control system function module subprogram design, communication protocol design between host computer and real-time controller.
