基于PSTN与Internet的嵌入式终端远程控制方案

The Long Range Control Project to Built-in Terminal by PSTN and Internet

嵌入式终端,因其体积小、价格低的特点应用广泛,在许多监控范围大、布点多,且传输率小的应用场合需要开发它的通信功能。本文在介绍智能家居系统的几种可行的远程控制方案和特点后,就各方案设计过程的关键技术进行详细的介绍。实践证明,各方案可以可靠地实现基于电话网的远程通信以及基于计算机网络的以单片机为核心和以嵌入式ARM9为核心的远程通信。

Because the characteristics of small and price low of the built- in terminal, so it is application extensive,it is need to The correspondence of the development function in application situation of the supervision scope big and many points and deliver a rate small. This article mainly introduces several kinds of the feasible long - distance control plan and the characteristics of the Home net- working and infrastructure technology, and then introducing the key technologies of the various project design. Practice has proved that the program can be reliably based on the long - distance telephone network, as well sa computer - based communications network to the core and single- chip ARM9 embedded at the core long- distance communications.
