一种基于LPC1788的互联网远程智能控制系统

摘要

为实现激光测距系统的远程控制和数据状态信息采集,提出了一种基于LPC1788微控制器的互联网智能控制系统.该系统使用FreeRTOS系统作为远程终端的实时操作系统,并基于emWin图形用户界面库开发了用户操作界面,然后使用LwIP网络协议栈实现了网络状态采集和控制通信,此外,系统采用微控制器自带UART的DMA模式实现了远程数据和状态信息的采集.该远程控制系统具有结构简单、可靠性高、稳定性好等优点,可以推广到其他智能控制系统和基于物流网的智能家居中.%To achieve remote control and data state information collection of laser range-finding system, a LPC1788-based remote intelligent control system of Internet is proposed. The FreeRTOS system is taken as the real-time operating system of re-mote terminal in this system. The user operation interface is developed based on emWin GUI, and then the network state acquisi-tion and control communication are realized by using LwIP protocol stack. Moreover the acquisition of remote data and state infor-mation is realized by adopting DMA mode of the microprocessor with UART. The remote control system has simple structure, high reliability and good stability, and can be extended to other intelligent control systems and logistics-based smart home.
