Utilizing pyroelectric effect, when having human body through out-of-date, the heat that two panels pyroelectricity element receives is different, and pyroelectricity energy is the most not
With, after signal processing circuit and amplifying circuit, microprocessor just can be by judging the width of human body sensor output pulse
Perception human body is from the distance of water heater, and the distance of perception can set according to the custom of user, has that response speed is fast, sensitivity
High, accuracy high.
Specifically, when described pyroelectric human body infrared sensor detects presence of people around described lampblack absorber, by institute
State the microprocessor described illuminating lamp of control, display lamp and display panel to light；The automatic point of described illuminating lamp, display lamp and display panel
Bright, it is preset to perform according to user, if user presets content difference, it is also possible to perform different operations.
When described pyroelectric human body infrared sensor detects around described lampblack absorber in the presence of nobody, described micro-process
Device controls described display lamp and display panel is closed, and makes described lampblack absorber enter Low-power-consumptiodormancy dormancy state.
Although aforesaid operations process is capable of lampblack absorber electric power starting, but during surrounding nobody, will not make display lamp
It is in bright state with display panel, and makes lampblack absorber enter Low-power-consumptiodormancy dormancy state, it is possible to save electric energy；Personnel to be operated need
When using lampblack absorber work, described pyroelectric human body infrared sensor detects presence of people around described lampblack absorber, i.e. can hold
Open described illuminating lamp, display lamp and display panel, make lampblack absorber enter duty.
Presence of people around lampblack absorber, and after illuminating lamp, display panel and display lamp are lit, following process can be carried out
(2) operation.
(2): described microprocessor detects whether described operation button is pressed, and perform according to the state of described operation button
Corresponding order；
Specifically, when described operation button is pressed, described microprocessor control to perform key commands；
When described control button is not pressed, continue to keep described illuminating lamp, display lamp and display panel to light.
After lampblack absorber performs corresponding action according to the order of operation button, the operation of following process (3) can be carried out.
(3): by described pyroelectric human body infrared sensor detect described lampblack absorber whether people are around exist, and will detection
Result is sent to described microprocessor, according to this testing result, described microprocessor controls whether described illuminating lamp closes；
Specifically, when described pyroelectric human body infrared sensor detects around described lampblack absorber in the presence of nobody, institute
State microprocessor to control to close described illuminating lamp；
When described pyroelectric human body infrared sensor detects presence of people around described lampblack absorber, described microprocessor
Control to continue executing with the order of described operation button.
This operating process is the operation carried out after microprocessor performs the order of operation button, and lampblack absorber is described
Have been carried out its one's work, next need to be judged whether operator forget to close by pyroelectric human body infrared sensor
Illuminating lamp, so carry out aforesaid operations.
After illuminating lamp is closed, the operation of following process (4) can be carried out.
(4): whether described microprocessor detects described blower fan and operating, and testing result is sent to described micro-process
Device, according to this testing result, described microprocessor controls whether described lampblack absorber enters standby mode；
