Drawings
The present invention will be further explained with reference to the drawings and examples.
FIG. 1 is a schematic block diagram of the present invention;
fig. 2 is a functional flow chart of the present invention.
Detailed Description
Example (b):
referring to fig. 1 and 2, the kitchen fire pre-alarm device includes a controller, and a circuit board is installed in the controller.
In this embodiment, the circuit board is integrated with a main processing module, a thermopile sensor, a PIR sensor (human body thermal sensor), a power supply, and a brightness detection module.
In this embodiment, the brightness detection module is a photoresistor, the power supply is a rechargeable battery, and the power supply can also supply power through mains supply access.
Specifically, the thermopile sensor is connected with the main processing module and is used for detecting the surface temperature of a cooker so as to judge whether a fire alarm is sent out or not, the thermopile sensor detects the surface temperature of the cooker through non-contact temperature detection, the PIR sensor is connected with the main processing module and is used for judging whether a person exists in a kitchen or not, the power supply is connected with the main processing module, the power supply is provided with a power supply control circuit for controlling the power supply voltage of a peripheral circuit, and the brightness detection module is connected with the main processing module and is used for detecting the brightness of light rays in the kitchen.
In this embodiment, the power supply further includes a low voltage detection circuit, and the power supply voltage of the peripheral circuit refers to the voltage of the acquisition circuits of the thermopile sensor and the PIR sensor.
In this embodiment, still include temperature detection module, temperature detection module connects the host processor and is used for detecting the ambient temperature in the kitchen, just temperature detection module is equipped with timing button.
In the embodiment, the multifunctional cooking utensil further comprises a radio receiving module and a loudspeaker module, wherein the radio receiving module is connected with the thermopile sensor and used for collecting sound emitted by the cooking utensil and sending the sound to the main processing module, and the loudspeaker module is connected with an indicator lamp.
In the embodiment, the main processor module judges whether to prolong the power-down awakening time of the power supply by receiving the information fed back by the photoresistor, when the photoresistor detects brightness in a kitchen, the power supply enters a shallow power-down state, namely the awakening time is short, and when the power supply detects darker brightness in the kitchen, the power supply enters a deep power-down state and is longer in awakening time, so that the power consumption of the whole device is reduced, and the service time is prolonged.
In this embodiment, the radio module is a noise reduction microphone, the noise reduction microphone collects the sound emitted by the cooker and feeds the sound back to the main processing module, and the main processing module judges whether to give an alarm according to the feedback information.
