资料介绍

用光电传感器、模拟电路和数字电路设计了一种红外报警实验装置,该装置由光发射、光接收、信号放大器、比较器及D触发器组成,当发射和接收之间的红外光被阻断时,系统持续发出报警信号。采用红外光调制技术,把红外光调制成脉动光,提高了红外光的辐射距离。详细分析介绍了该装置的电路原理及调试安装方法。实验结果表明,该装置电路典型、报警性能稳定且容易实现,非常适合作为本科生相关课程的综合设计性实验,以培养学生的创新和实践能力。

In this paper,an infrared alarm experimental system was designed with photoelectric sensor,analog circuit and digital circuit. This system is composed of light emitter,light receiver,signal amplifier,comparator and D trigger. The system will send out alarm signals continuously when the infrared light between light emitter and receiver was blocked. This system extends the radiation distance of the infrared light by modulating the infrared light into pulsed light with the modulation circuit principle,installation,and adjustment of the system were analyzed in detail. The experimental results indicate that the circuit of this system is typical and it is stable and easy to realize. It is fitted to be a comprehensive design e...
