针对某些单MCU结构的嵌入式Internet服务器性能价格比低且灵活性差的问题,提出了一种双MCU结构的嵌入式Internet接入服务器(DMCUEIAS)。它使嵌入式Internet的用户交互和设备控制分离,用户通过Internet不仅可以监视和控制现场设备,而且利用RAC可以将任务下载到现场;解决了低端单MCU处理能力低和高端MCU成本高的矛盾,并能够灵活地实现现场控制程序的功能扩展和升级。
In view of the low performance-price ratio and poor flexibility of embedded Internet servers in some single-MCU architecture, a dual-MCU Embedded Internet Access Server (DMCUEIAS) is proposed. It enables embedded Internet user interaction and device control separation, the user can not only monitor and control field devices through the Internet, and the use of RAC can be downloaded to the scene tasks; Solve the low-end single MCU low processing power and high-end MCU costs are high contradictions , And be able to flexibly expand and upgrade the functionality of on-site control programs.
