Detailed ways

Below in conjunction with accompanying drawing, technical scheme of the present invention is described in further detail:

The structural block diagram of the present invention as shown in Figure 1, comprises power switch, power supply module, single-chip microcomputer control circuit, contactor, setting button, liquid crystal display screen, A/D converter and the temperature sensor that is installed in each room. The power switch is connected with the power module to control the on-off of the power module, and the power module is connected to the single-chip microcomputer control circuit to supply power to the whole controller. The signal output end of the A/D converter is connected with the signal input end of the single-chip microcomputer control circuit, and each temperature sensor is connected with the signal input end of the A/D converter respectively, and is used for detecting the temperature value of each room Send it to the microcontroller through the A/D converter. The contactor is connected with the signal output end of the single-chip microcomputer control circuit for driving the heating boiler. The setting button is connected with the signal input terminal of the single-chip microcomputer control circuit, and is used for setting the appointment time and temperature value. The liquid crystal display is connected with the signal output end of the single-chip microcomputer control circuit, and is used for displaying the working state of the heating boiler.

The working process of the present invention is as follows: the user presses the power switch to control the power supply module to turn on the power supply, and the microcontroller control circuit enters the standby state after initialization. When the start-up time is reserved, the single-chip microcomputer control circuit collects the temperature values of each temperature sensor through the A/D converter and calculates the average temperature of each room through program calculation. If the temperature is lower than the set value, the single-chip microcomputer will output a signal to the contactor drive The heating boiler is turned on, if the temperature is higher than the set value, the microcontroller will output a signal to the contactor to drive the heating boiler to close. Users can intuitively view the working status of the heating boiler through the LCD screen.
