摘要
在新生婴儿在没人照看时采用监视和控制报警系统可以对宝宝爬出床、担心有人或者动物骚扰宝宝使用。基于AT89S51单片机的控制系统包括四部分:数据采集、-电路。该系统采用单片机进行控制,结构简单,还可进行多种功能的扩展,如实现多机通讯,对更大的场合进行监控与管理等。
。价格高昂,一般人们难以接受。如果再设计和生产一种价廉、性能灵敏可靠的报警器,必将在防盗和保证财产安全方面发挥更加有效的作用。由于红外线是不见光,有很强的隐蔽性和保密性,因此在防盗、警戒等安保装置中得到了广泛的应用,此外,在电子防盗、人体探测等领域中,被动式热释电红外探测器也以其价格低廉、技术性能稳定等特点而受到广大用户和专业人士的欢迎。
基于单片机控制的热释电红外报警,将检测到人体红外信号转换成电压信号,经调理电路整形处理为TTL电平送入单片机,单片机对送入信号进行判别,是哪一路报警信号,发出音响报警并通过数码管显示报警位置。适用于家庭、办公室、仓库、实验室等比较重要场合防盗报警。

Abstract
No one in the care of newborn infants when the alarm system used to monitor and control the baby can climb out of bed for fear of harassment was the baby or animal use. AT89S51 Microcontroller based control system consists of four parts: data acquisition, control systems and reporting voice prompts letter. E-circuit. The system uses a microcontroller to control, simple structure, but also for the expansion of a variety of functions, such as multi-munication, on the occasion of greater monitoring and management.
Alarm time is for people to solve many problems. But the alarm on the market for some panies are mostly financial institutions. Expensive, generally it is difficult to accept. If the re-design and production of a cheap, sensitive and reliable performance of the alarm, will ensure the property in the theft and play a more effective role. Is not seen as infrared light, has a strong hidden and confidentiality, and therefore security, guard and other security devices have been widely used, in addition, in electronic security, in areas such as human detection, passive pyroelectric infrared detectors also known for its low price, technology and stable performance by the majority of users and professionals e.
puter Control of pyroelectric infrared alarm, infrared signals to detect the human body into a voltage signal, the conditioning circuit for the TTL-levelplas
