入室搶劫事件屢見不鮮,針對此現象進行分析不難發現,造成失竊事件的極大原因是人們慵懶和意識差等不良性格造成習慣性不鎖門.本文以STC89C52單片機為基礎,設計了一種基于人體紅外傳感器的自動關門鎖門裝置,來解決此類問題.The incidents of burglary are so common. It is not difficult to find that the main reason for the burglary is the habit of unlocking of doors caused by people's laziness and poor consciousness. Based on the single chip microcomputer of STC89C52, a device used with infrared sensor of human body is introduced in this paper, which can achieve the effect of automatic closing and locking doors.
