| Abstract: | According to the inherent advantage of semiconductor chilling plate, the temperature acquisition and control system based on semiconductor chilling plate is designed in this paper. The hardware and software design of temperature acquisition and control system is introduced. Hardware of the system mainly consists of temperature acquisition module and semiconductor driver circuit. Temperature acquisition module is constituted by PTIO0 and its modulator circuit and A/D conversion circuit. IR2110 and IRFZ44N comprised the semiconductor driver circuit; due to the fuzzy type PID algorithm in design of the program, the performance of the system improved; the host computer software is written using Visual Basic 6.0. The experiments show that the system works well with high accuracy, good reliability and minor error ,with temperature control between 0-80℃, precision of 0.5℃. |
