模拟电子技术课程设计说明书 声光报警器 院 、 部： 电气与信息工程学院 学生姓名： 指导教师： 贾雅琼 职称 讲师 专 业： 班 级： 完成时间： 2012年5月25日 摘 要 声光报警器，是为了满足客户对报警响度和安装位置的特殊要求而设置。同时发出声、光两种警报信号。产品专用领域：银行、政府机关、邮政、酒店、工厂商场、商铺、别墅、ATM,周界防越系统及保安服务公司等； 是消防火灾自动报警系统中的一个配件产品。 声光报警器在实际的生活中可以见到许多，运用于生活的许多方面，既有硬件实现的，也有硬件和软件同时控制执行。通过这次的课程任务设计,我们可以很好的将课本知识运用于实践，同时也可以激发学生学习与专业相关的一些知识，从而扩大自己知识面的广度。 在本次课程设计中，前半部分用两只三极管制作一个多谐振荡器，并用它驱动两只发光二极管交替点亮Sound and light alarm, is in order to satisfy our customer to alarm loudness and installation position of the special requirements and Settings. Sound, light also issued two kind of warning signals. Product special field: Banks, government agencies, hotel, factory store shops, villas, ATM, the defense security service system and the company. Is the fire automatic fire alarm system in a spare parts. Sound and light alarm in actual life can see many, used in many areas of life, both hardware implementation, and hardware and software and the control of execution. Through this course task design, we can be very good to textbook knowledge and practice, at the same time it can stimulate the students learning in professional related some knowledge, in order to expand their knowledge of the breadth. In this course design, first half with two transistor make many harmonic oscillator, and it drives two leds alternate light; half of the use different types of two transistor amplifier circuit of a complex pipe, and realize the power amplifier functions to increase the volume of the buzzer. In the actual installation process, we can will two leds were installed to different places, and increase the utilization ratio. Key words: Transistor; Many harmonic oscillator; Complex pipe amplifier circuit; capacitance; LED; 目 录 1 总体设计方案介绍………………………………………………………………… 1 1.1 设计课题任务 ……………………………………………………………… 1 1.2 功能要求说明 ……………………………………………………………… 1 1.3 设计课题总体方案介绍及工作原理说明 ………………………………… 1 1.3.1 设计课题总体方案介绍……………………………………………
