Designation And Realization Of Intelligent Network Physical Therapy Controller

At present, in the medical profession, the more universal use physical therapy equipment all uses is the single plane operation pattern, a controller independently controla physical therapy equipment, brings inconvenientness for the hospital medical care personnel's use.According to the development company's request, we developed the controller which both has the network ability and has the single plane operate.It's convenient for medical care personnel's operation and the management. Uses this kind of operation pattern, can realize thephysical therapy work pathology management, provide the advanced management method and the pattern for the physical therapy work.This article proposed the system design plan, and through actualdesign verificated this plan's validity. This system uses monolithicintegrated circuit as primarily control chip, transforms through the temperature sensor after the A/D switching circuit intothe digital signal, uses the PID algorithm to carry on the control the boiler temperature. The user can make the choices of 9 kind of working patterns through the control panel pressed key and save the data of "the count down time value" ,"the operating temperature value", "the upper limit temperature value", "the lower limit temperature value"and "waitting temperature value" to EEPROM. The controller realizes multi-spots communication of PC and monolithic integrated circuit machine using the RS-485 communication protocol.
