Abstract: This paper describes a family dishwasher which has been applied for China Patents, it mainly introduces the wave-wheel dishwasher control system that adopts AT89S52 to be the control core. The article gives the hardware control circuit, provides the system’s main program and the keyboard interrupt program block diagram. Through practice, the system is operating reliably, its performance is stable, and can effectively complete the tasks of washing, disinfection and drying by full-automatic.

Abstract: This phototherapy takes full advantage of near infrared ray with high penetrability treating various pains and UVC curing gynaopathy, yet using the same control system. Introducing emphatically AT89S51 as the core to control circuit, utilizing PWM (Pulse-Width Modulation) produced by singlechip to manage the transmit power of light source and implementing the control system into hospital’s RS-485 monitoring network. Because of the machine serving several purposes, it makes the treatment efficiency higher and the cost lower.
