基于CPLD和PSTN的智能家居控制系统的设计

本文在智能家居控制系统研究和设计的现状上,论述了采用复杂可编程逻辑器件CPLD与单片机构成的双控制器为控制核心,利用公用电话网PSTN传递信息来实现智能家居的系统设计实现过程。和传统的控制系统中单独以单片机作为控制核心相比,其硬件连线复杂度,可靠性等方面都有所提高;和单独采用CPLD作为控制核心相比,克服了可编程逻辑器件的触发器资源非常有限,控制时序方面不足的缺点。信息传送利用公用电话网,与采用调制解调器(Modem)与计算机的结合来传送信息相比,其实现费用大为降低.

Design of Intelligent Home Control System based on CPLD and PSTN

Based on the design and research status of intelligent home control system,this paper discussed a intelligent home system which uses CPLD and Single Chip Machine as control core,transmits information by PSTN.Compared with traditional control system applying Single Chip Machine as internal control device,this system improved the complexity of hardware connectivity and reliability,.Compared with using CPLD separately,this system overcomes the very limited resources of CPLD and the shortcoming of control timing.Compared with transmission by the combination of Modem and computer,the costs of using PSTN to transmission information reduced significantly.
