Embodiment
Intelligent temperature controller be take single-chip microcomputer as core component, utilizes electric-contact mercury temp meter to carry out temperature setting, by the regulation and control of the connection of electric-contact mercury temp meter, break period are realized to the control to temperature.
Single-chip microcomputer to the switching state-detection of electric-contact mercury temp meter after, automatically identify and heat up or cooling.When heating up, adopt electric hot plate heating, single-chip microcomputer control methods; When cooling, adopt semiconductor cooler cooling, single-chip microcomputer control methods.Heating-cooling automatic identification circuit arranges after certain temperature value with electric contact mercury thermometer, may occur two kinds of situations: the temperature of (1) controlled device does not reach the temperature value of setting.Now electric-contact mercury temp is counted off-state (not conducting of WDJ), and 3 pin of operational amplifier U1A are high level, and its 2 pin is the fixed voltage obtaining after R1 and R2 dividing potential drop, and now 3 pin current potentials are higher than 2 pin current potentials, and 1 pin is exported high level.This high level is input to 6 pin of single-chip microcomputer; (2) the temperature inside the box has met or exceeded the temperature value of setting.Now electric-contact mercury temp is counted conducting state, method according to the above analysis, and 6 pin of single-chip microcomputer are low level.After the initialization of single-chip microcomputer electrification reset, first from 6 pin reading datas, as the above analysis, if be " 1 " from the data of 6 pin inputs, illustrate that controlled device needs to heat up, otherwise need cooling, single-chip microcomputer is identification intensification or cooling automatically accordingly.
