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.

實驗教學一直是工科教學中不可或缺的組成部分,對培養學生的動手能力,獨立思考能力,創新思維與發散思維具有重要的作用。針對目前電路教學實驗中電路仿真實驗與實物電路實驗各自獨立,無法統一問題,提出將仿真電路實驗與實物電路實驗有機的結合同步操作,并使用Web發布實現遠程實驗操作。采用Multisim作為電路實驗仿真平臺,NI Eiviss II作為實物電路實驗硬件平臺,運用LabVIEW整合Multisim電路仿真實驗與實物電路實驗,實現仿真與實物實驗有機結合,兩種實驗可同步進行。學生在仿真實驗中先可探索實驗,然后做實物實驗。同時運用LabVIEW開發出實驗過程人機交互操作接口界面,使用過程中效果良好。Experimental teaching has always been an indispensable part of engineering education.And it always plays an important role in cultivating students'practical ability,independent thinking ability,innovative thinking and divergent thinking.But simulation experiment and physical experiment cannot be unified in the circuit teaching experiment at present.In order to solve this problem,this paper proposes to combine organically the simulation circuit experiment with physical circuit experiment,and synchronously operate them.This paper uses the WEB publishing to achieve remote experimental operation.Multisim is used as the circuit simulation platform,and NI Eiviss II is used as the physical circuit hardware platform.Multisim circuit simulation experiment and physical circuit experiment are implemented by LabVIEW to realize the combination of simulation experiment and physical experiment.Students do explore experiments in simulation experiment firstly,and then do physical experiment.And this paper uses LabVIEW to develop the experimental man-machine interface.

介紹Socket 編程讓你沮喪嗎？從man pages中很難得到有用的信息嗎？你想跟上時代去編Intemet相關的程序，但是為你在調用connect（）前的bind）的結構而不知所措？等等…好在我已經將這些事完成了，我將和所有人共享我的知識了。如果你了解C語言并想穿過網絡編程的沼澤，那么你來對地方了。讀者對象這個文檔是一個指南，而不是參考書。如果你剛開始socket編程并想找一本入門書，那么你是我的讀者。但這不是一本完全的socket編程書。平臺和編譯器這篇文檔中的大多數代碼都在Linux平臺PC上用GNU的gcc成功編譯過。面且它們在HPUX平臺上用gcc也成功編譯過。但是注意，并不是每個代碼片段都獨立測試過。
