Abstract
t is designed by adopting SUNPLUS SPCE061A version 16-bits Single Chip Microcomputer; it has realized functions as manual setting temperature, automatic temperature control, showing the real-time temperature of water. The testing mode of water temperature adopts AD590 version integrated analog temperature sensor to perceive the temperature of water in vessels and uses operational amplifier to amplify minute analog voltage signal outputted by sensor. It employs keyboard scan mode to set target temperature (40°C~90°C) and displays dynamically the real-time temperature of water with digestion. The system controls the guide circuit and closing of the heating device by using relay circuit, achieving the aim of keeping design temperature constant essentially. PID algorithm is adopted in water temperature control method. The proportion, integration and differential constant in PID algorithm are debugged with experiments in order to control the proportion of heating time and reduce the adjusting time of the system. The system boasts the advantages of high controlling precision, stability and reliability, flexible operation, strong currency.
