【Abstract】 Perfusion hyperthermia is the first choice to treat tumor in the bladder.Accordingly,accurate measurement and control of the temperature of perfusion water is the key technology concerned with the curative effect of hyperthermia for the tumor in bladder.For different kinds of machines of hyperthermia currently at home and abroad,it is difficult to realize online monitor and high-precision control of the hyperthermia temperature of the tumor tissue in bladder.Aimed at this,this paper proposes a method to realize nondestructive measurement of the temperature of tumor tissue via a micro temperature sensor buried in the head of a triple-cavity tube.Applying fuzzy PID control algorithm,a control device based on MCU and CPLD is designed to perform online monitoring and intelligent control on the hyperthermia temperature of the tumor tissue in bladder.The experiment result shows that the method of real-time monitor and control on the hyperthermia temperature of the tumor tissue in bladder is feasible.The monitor and control system is running reliably,easy to operate and gets a good control effect.更多还原
