The Design Of Remote Access System
Abstract：this thesis is to design a family door security system, has a magnetic door monitoring, combustible gas detection, infrared detection functions such as access control security system, and through the Ethernet or GPRS transmission mode for remote monitoring, etc.This paper first discusses the remote access system research background, research status and research significance. Then, introduced in detail in this paper, the design of hardware circuit and software program of the remote system implementation process. The development of entrance guard system has the following features:1. The system is versatile and can be used for various applications such as image data acquisition, MMS alarm.2. Low cost, easy components procurement.3. The system hardware and software implement of the modular design, each module can separate, does not affect the system running.
