无线遥控自动窗帘的设计详解.docVIP

自动窗帘的设计 摘 要 本设计首先阐述了自动窗帘的基本构成及特点，然后通过对无线遥控控制方式，手动控制方式，光控控制方式的对比论证，根据控制要求，本设计选用了无线遥控和手动控制方式控制电机的正反转。通过对系统的总体设计、硬件和软件控制设计，满足了系统方案的要求。 在硬件方面，本文着重对单片机、无线接收模块J04V、无线发射模块F05P、直流电机驱动芯片L298N、三端集成稳压器KA7810等选型进行了设计，同时给出了各高级单元的使用及设定情况；在软件方面，提供了原理图、系统工作流程图和指令表。除此之外，也充分考虑了实际应用中的要求，设计时考虑到了成本、功耗、安全性、稳定性、抗干扰性等诸多问题，具有一定的合理性和可行性。 关键词 AT89S51单片机/直流电机驱动芯片L298N/无线接收模块J04V/无线发射模块F05P/三端固定集成稳压器KA7810/ The Design of the automatic curtain ABSTRACT First of all, the design of the automatic curtains on the basic structure and characteristics, and then through constant pressure on the wireless remote control way, manual control way, light control way of argumentation contrast, under the control requirements, many of the design selected the wireless remote control way and manual control way. Through the system design, hardware and software control design to meet the requirements of the system. In terms of hardware, this article focuses on microcontroller, the wireless receiver module J04V, the wireless transmitter module F05P, the DC motor driver IC L298N, the three-terminal integrated voltage regulator KA7810, such as selection of a design, all at the same time give the use of advanced units and set up the situation; In terms of software, provides a schematic diagram, the system flow chart and the instruction list . In addition, it fully takes into account the requirements of practical applications, the design takes into account the cost, power, security, stability, and many other questions of sexual interference with a certain degree of rationality and feasibility KEY WORDS AT89S51 Single-Chip Microcomputer / the DC motor driver IC L298N / the wireless receiver module J04V / the wireless transmitter module F05P / the three-terminal integrated voltage regulator KA7810 目 录 中文摘要 I 英文摘要 II 1 概述 1 1.1 选题意义 1 1.2 窗帘无线遥控器完成的功能 2 2 总体设计方案 4 3 AT89S51单片机概述 5 3.1 AT89S51单片机简介 5 3.2 AT89S51单片机的硬件结构及引脚 5 3.2.1 AT89S51单片机的内部结构 5 3.2.2 AT89S51单片机的外部引脚 7 3.2.3 AT89S51单片机的时钟电路及时钟信号 8 3.2
