Embodiment

[0028] The detailed flow and implementation of the method for intelligently turning on the refrigerator display screen of the present invention will be described below through embodiments. In this example, the human body motion sensing module uses a pyroelectric infrared sensor, and the human body ranging module uses an infrared distance sensor.

[0029] The pyroelectric sensor consists of a Fresnel lens, a housing, an optical filter, a pyroelectric element, and a field effect tube FET. The probe includes source A and source B. The human body is sensed by source A or source B successively through the probe. When P A >P B or P A B When the difference is generated, the detector has a signal output; when the thermal radiation of the environment or the human body changes, P A =P B There is no difference, the generated pyroelectric effects can cancel each other, and the detector has no signal output; the person moves vertically to the probe, P A =P B No difference is generate...

Abstract

The invention relates to a refrigerator, in particular to automatic control over a refrigerator display screen and provides a device for intelligently starting the refrigerator display screen. The purpose is to solve the problem that an existing refrigerator display screen can not perform displaying according to the relative state of a user and a refrigerator. The device comprises a human body movement sensing module, a human body distance measuring module, a processing module and a communication module. The human body movement sensing module is used for sensing the human body movement state. The human body distance measuring module is used for measuring the distance between the human body and a refrigerator. The processing module is used for receiving human body movement information of the human body movement sensing module and controlling the human body distance measuring module to start to work, the movement relation of the human body relative to the refrigerator is analyzed and judged according to the distance, measured by the human body distance measuring module, between the human body and the refrigerator, and an instruction for controlling the display screen to be started or shut down is transmitted to the refrigerator according to the movement state relation of the human body relative to the refrigerator. The communication module is used for being in data transmission with the refrigerator. The invention further provides a method for intelligently starting the refrigerator display screen. The method is suitable for the refrigerator.

Description

technical field [0001] The invention relates to refrigerators, in particular to automatic control of refrigerator display screens. Background technique [0002] With the gradual development of intelligent home networks and the application of various sensor technologies in the home appliance industry, the intelligence level of refrigerators has also been greatly improved. The so-called smart refrigerator is a type of refrigerator that can intelligently control the refrigerator and intelligently manage food. That is, it can automatically switch the refrigerator mode to keep the food in the best storage state at all times. It allows users to know the quantity of food in the refrigerator and information on freshness and quality preservation anytime, anywhere through mobile phones or computers. It can provide users with healthy recipes and nutritional taboos, and can remind them The user regularly replenishes food, etc. While the intelligence of refrigerators continues to impro...
