新型无线无线遥控门铃的设计(任务书,开题报告,外文翻译,论文11000字)
摘 要
本文介绍了一种新型无线遥控门铃,它采用具有编码功能的遥控发射-接收专用集成电路。该系统主要由处理模块、电源模块、编码模块、解码模块、显示模块、无线收发模块、声音模块等组成。本设计用单片机作为主控芯片,PT2262/PT2272集成芯片作为发射和接收主电路,还有DF超外差发射和接收模块。这种门铃具有功耗低,电路简单可靠,抗干扰能力强,遥控距离远,电路体积小等优点,其接收电路连同机电式音乐门铃为一体,可以随意放置在室内的某个地方,还可变换各种门铃音乐,使声音悦耳动听,满足不同人群的生活需要,具有广阔的发展前景。因此无线遥控门铃的设计成为本课题研究的目标。

The wireless remote control doorbell
Abstract
This paper introduces a new wireless remote control doorbell, which uses remote control transmitter with coding function - Receive ASIC. The system consists of processing modules, power supply modules, Encoding, decoding module, display modules, wireless transceiver modules, sound modules and other components. This design MCU as the master chip, PT2262/PT2272 integrated chip as the main transmitter and receiver circuits, and DF superheterodyne transmitter and receiver modules. This doorbell has low power consumption, somewhere in the circuit is simple, reliable, strong anti-jamming capability, remote distance, the circuit advantages of small size, together with its receiving circuit electromechanical musical doorbell as a whole, can be placed in the room, but also transform a variety of bell music, so melodious voice, to meet the needs of different groups, and has broad prospects for development. Therefore, the design of the wireless remote control doorbell become the target of this research. [来源:http://www.doc163.com]
