【摘要】：随动系统广泛应用于工业生产的各个领域,其种类繁多、功能各异。随动系统的运行状态直接影响到整个系统的性能,故对其进行性能测试非常必要。随动系统测控装置为随动系统的研制和测试工作提供了条件和手段。一般的随动系统测控装置都是针对一种系统而研制的,不具备通用性。因此设计一种适用于多种场合,集测试、分析、显示功能于一体的随动系统测控装置,具有非常重要的现实意义。本文提出了一种基于ARM的随动系统测控装置设计方案,采用基于ARM920T核的32位嵌入式处理器S3C2410作为核心控制CPU,具有RS485、CAN、16位并行接口等常用通信接口,LCD、键盘、USB等人机交互接口,可以满足大部分数字随动系统的测试需求；并且利用CAN总线扩展了以MCU为核心的轴角转换板,适用于模拟随动系统测试场合。测控装置使用嵌入式Linux系统作为系统软件平台,利用强大的图形界面工具Qt/Embedded完成测控软件的设计。用户可通过测控软件向被测随动系统发送典型测试信号(阶跃、等速、正弦)来测试随动系统的动静态特性,并绘制出指令、位置、误差三种波形曲线,具有友好的人机交互界面和完整的数据分析处理能力。实验表明,该装置能够满足随动系统测试的需求,具有多种通信接口、体积小、功能强、操作方便等特点,能够应用在多种数字、模拟随动系统的测试场合。
[Abstract]:The servo system is widely used in various fields of industrial production. The running state of the servo system directly affects the performance of the whole system, so it is necessary to test its performance. The measurement and control device of the servo system provides the conditions and means for the development and testing of the servo system. General servo system measurement and control device is developed for a system, not universal. Therefore, it is of great practical significance to design a measurement and control device of the servo system, which is suitable for various occasions and integrates testing, analysis and display functions. In this paper, a design scheme of measurement and control device for servo system based on arm is proposed. The 32-bit embedded processor S3C2410 based on ARM920T core is used as the core to control CPU.There are some common communication interfaces such as RS485CN-16-bit parallel interface, such as LCD, keyboard, USB and so on. It can meet the test requirements of most digital servo system, and extend the axis angle conversion board with MCU as the core by can bus, which is suitable for the test situation of analog servo system. The measurement and control device uses embedded Linux system as the system software platform and uses the powerful graphical interface tool QT / embedded to complete the design of the measurement and control software. The user can send the typical test signal (step, equal speed, sine) to the servo system by measuring and controlling software to test the dynamic and static characteristics of the system, and draw three kinds of waveform curves of instruction, position and error. Friendly man-machine interface and complete data analysis and processing ability. The experimental results show that the device can meet the test requirements of the servo system. It has many communication interfaces, small volume, strong function and convenient operation. It can be used in many kinds of digital and analog servo system testing occasions.
