Description
Technical field
This field is related to Smart Home technical field, and in particular to a kind of air conditioning control method based on microwave radar is
System and air-conditioning.
Background technique
Smart home is to have both intelligent building, network communication, information household appliances, lamps and lanterns automation, collection system using house as platform
Efficient, comfortable, safe and convenient, the environmentally friendly living environment that system, structure, service, management are integrated.With people's living standard
Raising, air-conditioning has become the necessity of Modern Family, can temperature-lowering heatstroke, a comfortably pleasantly cool rest and building ring is provided
Border.But, traditional air conditioner air-supply is the angulation change air supply direction that its blade is controlled by remote controler or mobile phone, user location
Change then needs to re-operate, very inconvenient for the awfully hot user for needing persistently to blow.The outlet air of existing air conditioner
Direction is mainly controlled by adjusting the position of outlet grid and slew page, and the shortcoming of this method is if when people moves position
The position of outlet grid and slew page must also be readjusted.In the case where number of operations is more, it is easy to keep user's generation cumbersome
Sense, greatly reduces user experience.
Panel-switch is closely bound up with daily life, and traditional lighting device by its structure simple, price
The advantages such as cheap, easy for installation are always in occupation of the main positions of illumination market.As people's living standard steps up, tradition
Panel-switch expose it is inconvenient to use in a dark environment, be easy to cause the defects of waste of energy to have been unable to meet people couple
In intelligent, energy-saving panel-switch demand.Based on the above reasons, controlled by sound and light panel-switch, infrared induction panel-switch,
Microwave radar inductive switch also gradually comes into vogue in recent years.
Controlled by sound and light panel-switch not only has energy-efficient effect, but also greatly improves the convenience used, wide at present
It is general to be applied in resident's corridor, building corridor, washing house and lavatory.Controlled by sound and light panel-switch utilizes sound and optical fiber
Variation carrys out control circuit to realize the switch of headlamp.Sound and light control switch is a kind of interior non-contact-point, in specific environment light

It lights, provides biggish convenience for people's lives.But controlled by sound and light panel-switch is easy to be led by Environmental Noise Influence
It causes switching frequency excessively high, be easy to cause the damage of lamps and lanterns.What is more, generally requires to manufacture the sound compared with high-decibel for trigger switch
Sound be easy to cause noise pollution.
Phased-array radar and phase controlling electron scanning array radar are arranged using the small size antenna unit of a large amount of unit controls
Arrange into antenna array, there are many a regularly arranged radiation and receiving unit composition on front is led to using Electromagnetic Interference principle
The phase that past each radiating element circuit is presented in computer control is crossed, the direction for changing wave beam is scanned, and antenna element believes echo
Number feeding host completes search, tracking and measurement of the radar to target.Microwave radar induction panel switch is sent out by flat plane antenna
Radio magnetic wave, when the range for having mobile object to enter electromagnetic wave, wave reflections turn back, and flat plane antenna receives the wave of feedback
After shape, subsequent conditioning circuit is acted through detection trigger switch.Microwave signal can pass through most of objects, so that microwave radar sensitive surface
Switching plate, which can be hidden, is installed on illuminator inside or other concealed locations, and can effectively track mobile object.
