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
