Now most plots all have installed the intelligence alarm system, Thus enhanced the plot safety rate greatly, this effectively guaranteed inhabitants person property safety. Because infrared is not exposed to light, Has strong confidentiality and the secrecy, Therefore in security, and so on security An Bao installed obtained the widespread application, In addition, In electron security, domains and so on in human body survey, Correlation infrared acquisition aid by its price inexpensive, technical performance stable and so on characteristics, Receives the user community and professionals welcome. This article introduced a section structure Infrared reports to the police the design realization which is simple, low cost, high stability quite. This thesis mainly introduces the hardware electric circuit, software design process, testing system. The gate magnetism infrared alarm apparatus use at89S52 monolithic integrated circuit, The monolithic integrated circuit is this system core component. Realizes each kind of sensing signal by the PT2272/2262,315M radio frequency to arrange the decoding launch and the receive, LCD1602 real time display password input condi
