摘要：

介绍了一种以中规模集成电路74148优先编码器为主,配合7447和门电路等中小规模集成器件,用断线触发报警代替热释电红外传感器,设计了一种以声音报警和数码显示为一体的防盗报警器。通过应用EWB5.0 仿真软件进行设计和模拟仿真,该设计实现了优先报警、多路数字显示等功能。能满足普通用户的需求,对生产制作价格低廉、布控点多、优先防范的报警器具有一定的意义。

Abstract:

This paper presents a scale of integrated circuits in both the main priority encoder 74148,7447,and the door with the small and medium-scale integrated circuits and other devices to trigger alarms with the break instead of pyroelectric infrared sensors.A functional and practical low cost voice alarm and digital display as one of the anti-theft alarm is designed.By the application of simulation software EWB5.0,the design realizes priority alarm,multi-channel digital display and other functions to meet the needs of ordinary users.The design is of value in the production of alarms of low-cost,multi dispatched points and prevention priority.

Key words: 74148;7447;digital display;priority alarm;alarm;EWB5.0
