The Design And Implementation Of Alarm System Based On FPGA

With the growing of national economy, the life level of people have improved a lot, andthe average GDP and family deposit amount have increased much. In this situation,the safetyof people’s lives and properties become more and more important,especially attracting widelyattention. Traditional guard solution relies human’s sense. Not only this method is lowefficient,but also the effect of guard relates to human’s body and spirit’s state, more seriously,the criminal proof is hard to collect. Recently,the rapid development of industrial automationand computer technology make the safe guard jobs generally undertook by people graduallyreplaced by computer safe guard system. Because the tired problem of human does not exist incomputers, monitoring could consistently being running with the same criterion in twenty fourhours. Moreover computer technology reduces the cost of surveillance, improve theproductivity and obtain highly economic benefit and social benefit.The rapid development of Embed system technique and EDA technique provides newsupport for our anti-theft alerting system. We develops a anti-theft device based on EDAtechnique and FPGA technique. It integrates a few sensor modules and GSM communicationmodules, which is combined by EDA technique, fulfilling sensors parameter integration, alertcondition’s judging and twenty-four-hour monitoring. The system proposed by this paperassures guarders monitor the whole buildings and be informed of the house position in whichtheft has happened and the time.This paper chooses STC12C5A60S2as the core board, YX-7100infrared human sensors,WT588D erasable voice module and GSM module to form the device hardware module. Byscanning the alarm signal and message signal, the core controller then sends the order back toevery module.The logical control function of core board is designed by VHDL language.During the process of design, the manner of parallel and sequential is combined, and StateMachine is added to guarantee it can run in real-time.System software is designed by QT. Itcompromises login authentication step and large-scale building rooms monitoring, by which all the real time state of monitoring place is showed friendly. Guarders can monitor the palacedirectly.The system through the market are fully the requirement analysis and to a large numberof customer personnel visit by understanding the needs of the market based on thedevelopment of research focused on, it realized integrated voice chip replaced the traditionalelectronic display screen, effectively reduce the system overall power consumption.In addition,by introducing FPGA technique and EDA technique to develop the hardware logic andcommunicating protocol,the development time is decreased,and device volume is reduced,making the system more forthright and the device more small.
