Temperature control of heating, read, display shows the temperature, temperature, high temperature alarm, heating in low temperature and set temperature threshold

CodePudding user response:

Temperature sensors data, single chip microcomputer calculating distance target temperature difference, and then according to the difference size to generate different duty cycle of square wave, square wave duty ratio means heating level, such as to do 256 levels of heating, continuous output 1, 256 is the total power output, continuous 256 0, said no heating, 128 1128-0, representative in 1 and a half to the heating power, the more close to the target temperature, the more output of 0, and then use square wave to control thyristor, thyristor electric heating wire,,,,
