题目:基于单片机的家用红外按摩仪设计

摘要

本课题主要是家用远红外按摩器控制系统设计。在设计开始之前必须先了解远红外按摩器设计要求、实现功能。由此设计硬件电路，并按照要求选择合适的器件。硬件电路主要是利用单片机作为最小系统，外扩展一系列其他模块电路来实现功能。主要包括设计霍尔传感器电路，实现位置控制；设计继电器电路，控制按摩、震动和远红外加热；设计时针电路，实现实时时间显示及定时控制；设计电源电路，具有+12伏、+5伏和+6伏输出等。软件设计则应根据现有的硬件电路，和制定的工作流程编写。

远红外按摩器系统的工作原理主要是通过用单片机作为主控部件，霍尔传感器作为位置采样部件，固态继电器及小型双路继电器作为开关部件，时钟芯片作为实时时钟及定时部件，蜂鸣器作为状态提示部件，外扩按摩电机，震动电机，远红外加热板，实现按摩器定位按摩，选择震动，选择远红外加热及实时时间显示和定时等功能。除此之外，还可以通过按键电路的按键进行数据的复位，确定和选择等操作，以达到能根据用户的实际需求灵活的修改工作参数，让用户可以很方便的寻找到合适的按摩方式。

ABSTRACT

The main topic is the far infrared massage bed control system design .At the beginning of the design before the Jie Yuan infrared massage bed design requirements ,to achieve functional.The design of the hardware circuit,and in accordance with the requirements to choose the right device.the hardware circuit is mainly the use of single-chip microcomputer as a minimum system,and a series of other expansion module circuit to realize the function of.Mainly includes the design of Holzer sensor circuit,to realize the position control;design of relay circuit,the control massage,vibration and far infrared heating;clock circuit design,to achieve real time display and timing control;design of power supply circuit,with the +12V,+5 volts and the +6 volt output,Software design should be based on existing hardware circuit,and make the work process to prepare.

Far infrared massage bed control system principle of work mainly by using the single chip as the main control unit,Holzer sensor as the position sampling part,solid state relay and small dual relay as part of the switch,the clock chip as a real time clock and timing components,buzzer as the state prompting part,spread the massage motor,vibration motor,far infrared heating plate realization of positioning massage,massage bed,selsction of vibration,selection of far infrared heating and real time display and timing functions.In addition,but also through button circuit keys for data reduction,identification and selection of operation,in order to achieve according to the user’s actual demand for flexible modify operating parameters,so that users can easily find the suitable way of massage. Key words:minimum system;hardware circuit;work flow;software design
