Intelligent refrigerator control system and method based on position and distance analysis

Abstract

The invention discloses an intelligent refrigerator control system and method based on position and distance analysis, and relates to the technical field of intelligent refrigerator control. The system comprises an intelligent controller, a human body infrared sensor, a radar positioning sensor and an intelligent refrigerator display screen; the human body infrared sensor and the radar positioning sensor are both installed on the outer side face of a refrigerator door body; and the intelligent controller is in electric signal connection with the human body infrared sensor, the radar positioning sensor and the intelligent refrigerator display screen. After the intelligent controller receives human body information transmitted by the human body infrared sensor, the intelligent controller controls the radar positioning sensor to emit high-frequency waves so as to obtain position information of a plurality of users; if the intention of the user is to 'use the refrigerator', the intelligent controller controls the intelligent refrigerator display screen to reduce noise or lighten the screen; if the intention of the user is 'unsuggested to pass by the refrigerator ', the intelligent controller does not control and process the intelligent refrigerator display screen; and the intelligent control efficiency is improved, and misoperation is avoided.

Description

technical field [0001] The invention belongs to the technical field of refrigerator intelligent control, and in particular relates to a refrigerator intelligent control system and method based on position and distance analysis. Background technique [0002] At present, the home appliance industry is gradually tending to be intelligent, and human body sensing, as one of the achievements of intelligentization, has also attracted much attention. At present, there are two kinds of sensors commonly used on the market: passive human body pyroelectric infrared sensors (because the human body emits infrared rays, which are then enhanced and gathered on the infrared sensing source through a Fresnel lens, and then sense the presence of people) and active sensors. The human body induction infrared sensor (by actively emitting infrared signals, emitting through the transmitting module, and receiving the module to jointly complete the induction of the human body), is low in price and has...

Problems solved by technology

At present, there are two kinds of sensors commonly used on the market: passive human body pyroelectric infrared sensors (because the human body emits infrared rays, which are then enhanced and gathered on the infrared sensing source through a Fresnel lens, and then sense the presence of people) and active sensors. The human body induction infrared sensor (by actively emitting infrared signals, emitting through the transmitting module, and receiving the module to jointly complete the induction of the human body), is cheap and has low device power consumption, but it also has certain limitations: it cannot detect the distance between the human body and home appliances, and When the human body is close to the home appliance, it is impossible to judge whether to pass the home appliance or use the home appliance
