Family autoalarm system has prompt , accurate , handle a simplicity , utility advanced merit, and the person applies can realize fire prevention , guard against theft still having the effect crying for help emergently broadly.

家庭自动报警系统具有迅速、准确、操作简单、实用性高等优点，而且其运用广泛，能实现防火、防盗还有紧急求救的作用。

Numerical control lathe have following outstanding superiority than traditional lathe include:Can process out complicated parts, such as the curve coming out in traditional machine tooling, curved surface,etc;Because computer have superb operation ability is can instantaneous to calculate out each coordinate axis instantaneous amount of exercise that should move accurate, So can compound into the complicated curve or curved shttp://www.51lun-wen.cnurface ;Can realize automation that process is and flexible automation, so efficiency constant traditional lathe raises by 3-7 times;Because the computer has memory and stores ability ,Can carry out automatically according to the order that the procedure stipulates,so realize automation;Proceshttp://www.51lun-wen.cnng precision of part high, size disperse degree light, make and assemble easy, No longer need to" repair the damaged parts of a machine and supply replacements";Can realize the concentration of many processes,have many kinds of self-containment functions,such as autoalarm, controlling, automatic compensation automatically,etc;Therefore can realize that nobody guards and processes for a long time.

机床数控化改造可以加工出传统机床加工不出来的曲线、曲面等复杂的零件。数控机床比传统机床有以下突出的优越性，由于计算机可以瞬时准确地计算出每个坐标轴瞬时应该运动的运动量，因此可以复合成复杂的曲线或曲面；可以实现加工的自动化，而且是柔性自动化 http：//www.51lun-wen.cn ，从而效率可比传统机床提高3～7倍；由于计算机有记忆和存储能力，可以将输入的程序记住和存储下来，然后按程序规定的顺序自动去执行；加工零件的精度高，尺寸分散度小，使装配容易，不再需要"修配"；可实现多工序的集中，减少零件在机床间的频繁搬运；拥有自动报警、自动监控、自动补偿等多种自律功能，因而可实现长时间无人看管加工。

Speaking from the function, the long-distance image surveillance system can be divided into two parts. The first part is a module of signal gathering and control. It uses AT89C51 as the main processor, which includes sensor signal measure, autodial, circuit state measuring, DTMF signal decoding, and automatic control.

从功能上讲，远程图像监控系统大至可分为两部分：第一部分是以A789C51为主处理器的信号采集和控制单元，包括传感器信号检测、自动拨号、线路状态检测、DTMF信号解码和自动控制五个小模块，用以实现对现场信号的采集、自动拨号报警和远程控制。
