摘要
在分析家居门禁系统发展的基础上,结合实际情况,提出了基于家庭自动化专用modemST7537HS1和AT89C51单片机的多功能可视对讲门禁系统的总体方案与系统构成,并讨论了系统的硬件组成、工作原理及其软件实现方法。该系统利用现有的220 V电力线作为通信总线,实现了信息传输线路与动力线路的合二为一。
On the basis of analyzing the development of the door-entry control system in our country, combining the present conditions of our nation, the overall scheme and the structure of the visual inter-conversation door-entry control system based on the home automation modem ST7537HS1 and AT89C51 is presented. The discussion has been made for the hardware, operation principle and the method of software of the system. Using the 220 V power line which is already existing as the communication bus to realize the syncretism of the communication line and the power line.
