Wherein, radar sensor 5 is arranged between refrigerator doors and refrigerator body, and refrigerator doors pull rod device 4 is arranged in ice
At the connecting shaft of chamber door and refrigerator body.
Refrigerator master control version 1 controls for realizing the operation of refrigerator entirety；Refrigerator control display board 2 is for providing button operation
Interface and buzzer warning module；Refrigerator lighting lamp 3 is used to illuminate refrigerator inside when refrigerator doors are opened；Refrigerator doors pull rod fills
It sets 4 to be made of pull rod motor and motor drive controller, motor drive controller is used to execute the instruction of refrigerator master control borad 1, draws
Bar motor realizes the operation of closing refrigerator door under the control of motor drive controller；Whether radar sensor has for incuding
People exists and the movement tendency of people, induction information is sent to refrigerator master control borad 1, induction information here may include whether
Presence of people, people are at a distance from refrigerator and people is proximate to or separate relative to the movement tendency of refrigerator.
Optionally, in practical applications, radar sensor can be microwave radar human body sensing device, microwave radar people
Body induction technology has the characteristics that detection range is remote and detection accuracy is high.
It can be real by conventional techniques known to those skilled in the art for the detection method of radar sensor
It is existing.
Fig. 2 is the flow chart of refrigerator doors control method provided by one embodiment of the present invention, and this method is applied in such as Fig. 1 institutes
In the refrigerator doors control system shown, as shown in Fig. 2, refrigerator doors control method may comprise steps of：
Step 110, whether detection refrigerator doors are opened.
Step 120, when refrigerator doors are opened, start radar sensor.
After user opens refrigerator doors, refrigerator starts radar sensor, detects position of human body in real time.Here detection
May include detection refrigerator around whether someone, detect the distance between people and refrigerator, and detect human body relative to refrigerator
Movement tendency is proximate to or separate.
Optionally, after starting radar sensor, can also include the following steps：
The first step judges the movement tendency of people by radar sensor.
Second step, when people is when close to refrigerator, control refrigerator lighting lamp brightens.
Third walks, and when people is when far from refrigerator, control refrigerator lighting lamp is dimmed.
In practical applications, when people is close to refrigerator, it may be possible to need to be put into from taking-up food in refrigerator or into refrigerator
Food, refrigerator lighting lamp is lightened can check the region in refrigerator in order to user, when people is far from refrigerator, may have been taken out
Food is completed food and is put into, and the focus of user may not be in refrigerator inside, and the brightness of refrigerator lighting lamp is dimmed can be with
Save electric energy.
