入室抢劫事件屡见不鲜,针对此现象进行分析不难发现,造成失窃事件的极大原因是人们慵懒和意识差等不良性格造成习惯性不锁门.本文以STC89C52单片机为基础,设计了一种基于人体红外传感器的自动关门锁门装置,来解决此类问题.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.

实验教学一直是工科教学中不可或缺的组成部分,对培养学生的动手能力,独立思考能力,创新思维与发散思维具有重要的作用。针对目前电路教学实验中电路仿真实验与实物电路实验各自独立,无法统一问题,提出将仿真电路实验与实物电路实验有机的结合同步操作,并使用Web发布实现远程实验操作。采用Multisim作为电路实验仿真平台,NI Eiviss II作为实物电路实验硬件平台,运用LabVIEW整合Multisim电路仿真实验与实物电路实验,实现仿真与实物实验有机结合,两种实验可同步进行。学生在仿真实验中先可探索实验,然后做实物实验。同时运用LabVIEW开发出实验过程人机交互操作接口界面,使用过程中效果良好。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.

介绍Socket 编程让你沮丧吗？从man pages中很难得到有用的信息吗？你想跟上时代去编Intemet相关的程序，但是为你在调用connect（）前的bind）的结构而不知所措？等等…好在我已经将这些事完成了，我将和所有人共享我的知识了。如果你了解C语言并想穿过网络编程的沼泽，那么你来对地方了。读者对象这个文档是一个指南，而不是参考书。如果你刚开始socket编程并想找一本入门书，那么你是我的读者。但这不是一本完全的socket编程书。平台和编译器这篇文档中的大多数代码都在Linux平台PC上用GNU的gcc成功编译过。面且它们在HPUX平台上用gcc也成功编译过。但是注意，并不是每个代码片段都独立测试过。
