WU Jian-jin, LI Jian-qing, WU Jian-feng, et al. Hardware design of a surface-temperature signal fast generation device[J]. 2011, 30(1): 104-106. DOI: 10.13873/j.1000-97872011.01.036.
For the occasion of surface-temperature signal need quickly change
a fast surface-temperature generation device is designed.This device includes semi-conductor refrigeration
water-cooling system
infrared sensor
LCD and so on.Adopting semi-conductor refrigeration as the temperature signal generation device
a bridge is adopted to change the voltage polarity at both ends of the semi-conductor refrigeration and a voltage regulator circuit to regulate the voltage continuously
using infrared sensors to real-time monitor surface temperature of the device to carry out closed-loop control.This device can be used for representation thermal tactile and other occasion which needs rapidly change of surface temperature signal.
