嵌入式智能防盗报警系统
Abstract
With the advancement of digital information technology, network
technology and integrated circuit technology, embedded system has been
widely used in the development and design of electronic products. There
are more advantages of applying embedded system in Safe-guard system design
and implementation, such as modularizing system development, simplifying
the development procedure, cutting down developing period and cost, and
improving system performance. So it is a general trend to apply embedded
system in safe-guard system design.
By studying the current situation and advancement trend of safe-guard
system, this paper presents an overall solution of embedded intelligent
safe-guard system. The implementations of the system include the following
four aspects:
1. Basic principles and hardware circuits of sensors used in the system
are detailed.
2. Main processing unit selection of the alarm host is first paid more
attention, and then the hardware and software implementation of
power modular, real-time clock modular, alarm input modular, serial
communication modular, remote controlling modular, keyboard
modular, LCD display modular, telephone dialing modular, alarm data
storage modular, and alarm voice playing modular are all detailed
presented.
3. Surveillance software using electronic map is developed
