摘要
简易自动响铃装置是生活中常见的报警装置,报警装置在生产和生活中是随处可见的,它虽然并不复杂,但是在日常的生产生活中起着十分重要的作用,比如一些容易发生危险的地方,人多的场合,如果将要发生危险,报警装置可以提前通知人们,达到防患于未然,在小的方面应用也很多,在这就不一一列举,以前报警装置一模拟电路为主,但由可编程器件构成的电路现在明显比模拟电路优点多,可编程序控制器是一种数字运算操作电子系统,专为在工业环境下应用而设计。它采用了可编程序的存储器,用来在其内部存储执行逻辑运算、顺序控制、定时、计数和算术运算等操作的指令,并通过数字的,模拟的输入和输出,控制各种类型的机械或生产过程。所以可编程逻辑器件现在是主流!

English abstract
Simple automatic ringing device is mon life of the alarm device, alarm device is in production and daily life everywhere, while it is plicated, but in daily production plays an important role in life, such as a number of risk-prone places, people and more occasions to be dangerous if the alarm device can inform people in advance, to take preventive measures, the application in small and there are many that do not list them in the past, an analog circuit-based alarm However, the circuit formed by a programmable device is now significantly more than the advantages of analog circuits, programmable logic controller is a puting operate the electronic systems in industrial environments for applications. It uses a programmable memory, used to implement logic in its internal memory operations, sequence control, timing, counting and arithmetic instructions such as operation and, through digital, analog input and output, control various machines or production process. So now the mainstream programmable logic device!
