【摘要】：随着科学技术不断向前发展，，电子电器设备涌现出越来越多的由计算机远程控制的程控仪器和设备，计算机与外围设备之间的良好通信问题成为当下电子电器领域的主要研究课题。由于现代技术导致的计算机和外围设备之间的数据通信量越来越大，数据类型越来越复杂，对通信要求越来越高，传统的通信方式已经渐渐地不能适应当下飞速发展的电子科技。此时，USB（UniversalSerialBus）以其独有的速度快、使用灵活方便、支持热插拔等优势迅速占领了通信传输界的市场，从此，串行通信总线技术在计算机通信和自动控制领域得到了广泛的应用。本文首先分析了半导体激光器恒流驱动器的一系列优缺点，并根据现有国内外研究现状提出了半导体激光器恒流驱动器所面临的瓶颈问题，提出了解决这一问题客观必要性和迫切性。同时学习了单片机技术和串行通信理论，了解了USB总线系统的基本特征、通信协议等基础知识，掌握了USB通信的基本原理和过程，在实验室原有程控仪器半导体激光器恒流驱动器的基础上，设计完成对半导体激光器恒流驱动器的上位机控制工作。接着，本论文着重研究了半导体激光器恒流源的工作原理和运行方式，在其原有硬件环境的基础上，运用面向对象编程的MFC编程模块成功编译了具有上位机控制功能的系统软件，达到了由计算机远程控制半导体激光器恒流驱动器的目的。与此同时，本论文应用该上位机控制软件，对不同的工作模式下的恒流源工作时电流进行采样，并利用MATLAB对所得数据进行处理分析，实现对恒流源的稳定性研究。
[Abstract]:With the continuous development of science and technology, more and more program-controlled instruments and devices controlled by computers have sprung up. The problem of good communication between computers and peripherals has become the main research topic in the field of electronics and electrical appliances. As a result of modern technology, the amount of data communication between computers and peripherals is increasing, the data types are becoming more and more complex, and the communication requirements are becoming higher and higher. The traditional communication mode has been gradually unable to adapt to the rapid development of electronic technology. At this time, the USBU Universal Serial bus (USB) has occupied the market of the communication transportation field rapidly because of its unique speed, flexibility and convenience, supporting hot swapping and so on. Since then, the serial communication bus technology has been widely used in the field of computer communication and automatic control. In this paper, firstly, a series of advantages and disadvantages of semiconductor laser constant current driver are analyzed, and the bottleneck problem of semiconductor laser constant current driver is put forward according to the current research situation at home and abroad. The objective necessity and urgency of solving this problem are put forward. At the same time, we study the technology of single-chip computer and serial communication theory, understand the basic characteristics of USB bus system, communication protocol and other basic knowledge, master the basic principle and process of USB communication. On the basis of the original program controlled instrument semiconductor laser constant current driver in laboratory, the upper computer control of semiconductor laser constant current driver is designed and completed. Then, this paper focuses on the working principle and operation mode of semiconductor laser constant current source, based on its original hardware environment. The system software with the function of upper computer control is compiled successfully by using the MFC programming module of object-oriented programming, and the purpose of remote controlling the constant current driver of semiconductor laser by computer is achieved. At the same time, this paper applies the control software of the host computer to sample the current of the constant current source under different working modes, and to process and analyze the obtained data by using MATLAB to realize the stability research of the constant current source.
