Single-chip computer-based embedded multi-motor intelligent control system

摘要:

采用传统的电机控制系统应用模拟器来模拟整个电机的控制，虽然可操作性强，但存在控制效果差的问题，针对该问题，提出了基于单片机的嵌入式多电机智能控制系统设计。选用嵌入式单片机 dsPIC20F芯片无需过多的外设装置，以此设计系统硬件结构，获取感应器转子转速差，并将其转化为相应的信号，控制电机。选用AD_TCP-01型号A/D 数据采集器，在300米范围内可通过互联网进行超远程控制与传输。选用M57962AL是厚模单列直插式封装驱动模式，实现良好过流保护作用。使用NMRV075步进电机作为一种实用传动设备，符合单片机需求，输出扭矩也相对较大。采用嵌入式实时操作系统 μClinux，分别设计任务调度流程、单片机程序和PC上位机，由此完成嵌入式多电机智能控制。在Proteus仿真软件支持下进行系统调试，由调试结果可知，该系统控制效果最高可达到0.996，为提高电机工作效率奠定基础。

Abstract:

The traditional motor control system application simulator is used to simulate the entire motor control. Although the operability is strong, there is a problem of poor control effect. In response to this problem, a design of an embedded multi-motor intelligent control system based on a single chip is proposed. The embedded single-chip dsPIC20F chip is used without the need for too many peripheral devices. Based on this, the system hardware structure is designed to obtain the difference in speed of the rotor of the inductor and convert it into corresponding signals to control the motor. AD / TCP-01 A / D data collector is selected, which can be used for ultra-remote control and transmission through the Internet within 300 meters. M57962AL is selected as the thick-mode single-in-line package driving mode to achieve good overcurrent protection. The NMRV075 stepper motor is used as a practical transmission device, which meets the requirements of single-chip microcomputers and has relatively large output torque. The embedded real-time operating system μClinux is used to design the task scheduling process, the single-chip computer program and the PC host computer, thereby completing the embedded multi-motor intelligent control. The system debugging is performed with the support of Proteus simulation software. From the debugging results, it can be known that the system control effect can reach up to 0.996, laying a foundation for improving the working efficiency of the motor.
