Embodiment Construction
[0022] The present invention will be further described below in conjunction with drawings and embodiments.
[0023] Such as figure 1 , The power supply circuit uses a power frequency transformer to change the mains power to 12V, and after rectification, filtering and integrated voltage regulator 7805 to stabilize the voltage, the 12V AC power is changed to 5V DC power for use by microcontrollers and other circuits.
[0024] Such as figure 2 , The single-chip main control circuit is the core of the whole circuit, which is composed of AT89S52 single-chip microcomputer, clock circuit and reset circuit, which provides control signals for all peripheral module circuits.
[0025] Such as image 3 , in the heating module circuit, when the system starts and the temperature reaches the temperature set by the user, the voltage of the same input terminal of the comparator is higher than the voltage of the reverse input terminal, the output signal of the comparator, the triode conducts...
