分布式远程运动控制研究

随着因特网的迅速发展，通过因特网实现对设备运动的远程控制已成为当前的研究热点。该文提出了一种利用嵌入式Web Server将设备直接接入因特网，而实现分布式远程运动控制的设想。并以步进电机的远程监控为例，在ARM上实现一个具有最小功能的嵌入式Web Server，完成对网络包的处理，得到包含在HTTP包中的控制信息；同时采用计数器中断的方式实现对步进电机的控制，使得处理网络包和计数器输出控制脉冲可以并行实现，从而在ARM上实现了整个步进电机远程监控系统。

The Research on Distributed Long-Distance Movement Control

With the rapid development of the Internet, remote control of the movement of devices through the Internet has become a research focus. The article presents a design that can connect a device to the Internet directly through an embedded Web server. Taking the example of the remote control of step-in electromotors, we design a minimal functional embedded Web server on ARM. It analyses the Internet packets and achieves the control information which is included in the HTTP data. According to the control information, the way of counter interrupt is adopted to control the electromotor. On this basis, the remote control system for step-in electromotors on ARM is implemented.
