Temperature control electronic system using single chip microcomputer

Abstract

The invention discloses a temperature control electronic system using a single chip microcomputer. The system includes a temperature control device, a parameter setting module, a temperature control adjustment module and a single chip microcomputer module. According to the temperature control electronic system, the temperature of a first temperature collecting layer is monitored comprehensively through a contact type temperature sensor and a non-contact type temperature sensor (an infrared temperature sensor) simultaneously. Since the first temperature collecting layer and the second temperature collecting layer are heat transfer plates with holes, effective heat dissipation can be ensured; at the same time, the moment of shutting down a heating unit / refrigerating unit is determined through a temperature average, an average temperature rise / cooling speed value and a threshold temperature, and the heating unit / refrigerating unit is shut down ahead of time, the stable control of the temperature is ensured with high precision, so that the temperature control electronic system is high in precision and good in stability; besides, through the maximum or minimum temperature among the temperatures obtained by the contact type temperature sensor and the non-contact type temperature sensor, the wind speed of a fan is adjusted in real time, uniform heat exchange is effectively ensured, and sudden changes of local temperature are avoided.
