碩士 === 國立臺灣科技大學 === 電子工程系 === 100 === LED/LCM and key pad are the most common way for user interface (UI) to do human-machine interactions and information display. The single task embedded system can handle this functionality easily. However, when the system full with information and complicated, simple human-machine interface design could not handle these complicated operations effectively and thus be very unfriendly and even dangerous to users. Recently, control through Ethernet, TCP/IP and WEB-GUI is becoming more and more popular. This not only gets rid of weakness of the traditional LED/LCM and Key pad operation, which unable able to tackle complicated settings, but also makes remote control possible. With a mobile device, users in remote location can conveniently communicate and control the embedded system. Traditionally embedded, HTTP and Browser systems can only handle text information from hyperlinks, not interactive UI operations. To improve this on the embedded system with limited resources, the design a cortex-M3 embedded control system based on jQuery, AJAX uses FreeRTOS, and LWIP to realize remote control through web applications. The intension of the design is to enhance controller performance and facilitate user interface operation. According to our implementation and testing results, the architecture of the system is highly feasible and reliable. It can be used on a diversity of platforms to perform the WEB-GUI control function. Because the system cost is low compare with full Linux-based system or PC-based system, it can be applied in simple and reliable industrial controls, unmanned data acquisition systems, and distributed remote control systems.
