With reference to Fig. 4 and Fig. 5, the specific embodiment of invention is illustrated.
As shown in figure 4, air-conditioner 40 according to an embodiment of the invention, two pyroelectric sensors are installed, in such as Fig. 4
Shown in 402, visual angle 180 degree, then after air-conditioner is mounted to a wall, human body sensing detection can cover whole room, its specific work
Make flow process as shown in figure 5, including：
Step 50, detects in room whether someone by pyroelectric sensor, if having, execution step 51, and otherwise execute step
Rapid 52.
Step 51, maintains the current operating conditions of air-conditioner.
Step 52, the unmanned persistent period in statistics room.
Step 53, judges whether the persistent period is more than setting time t1, if so, execution step 54, otherwise maintains air-conditioner
Current operating conditions.
Step 54, is switched by current operating conditions and accesses energy-saving run state, the Working mould being presently according to air-conditioner
Formula adjustment work temperature.
Step 55, judges whether the persistent period is more than setting time t2, if so, execution step 56, is otherwise maintained at energy-conservation
Running status.
Step 56, controls air-conditioner to enter standby running status.
In an embodiment of the present invention, pyroelectric sensor is used as human body detection device, by pyroelectric sensor
Detection room whether someone, specifically, this pyroelectric sensor, by infrared detection mode, can complete whole in special angle
The human detection of closed room, can carry out region division to whole space by this pyroelectric sensor, be divided into multiple regions,
Usually, whether each pyroelectric sensor corresponds to a region respectively, be further capable of detecting when in the region marking off
Someone, by judging regional whether someone, is capable of the wind people of control realization air-conditioner air-supply, wind keeps away people's function.
After air-conditioner starts, pyroelectric sensor starts the object in region to be scanned detect, right according to detection
The state of elephant, can make corresponding action pattern, realize air conditioner energy saving.Executing flow process is：Human body monitoring output identification knot
Fruit execution respective action.After wherein human body monitoring is opened, whether pyroelectric infrared sensor module can have in scanning space
People, carries out pattern discrimination according to scanning result.If detecting unmanned, start to calculate the persistent period of unmanned state, if
The persistent period of unmanned state is more than time t1, when during refrigeration, if design temperature is heightened mass dryness fraction, heats design temperature turn down some
Degree, is such as defaulted as heightening or turn down 2 degrees Celsius, not switch mode after automatic temperature-control；If the persistent period of unmanned state is big
In time t2, control air-conditioner standby.If human body monitoring Status Change, if that is, homoiothermic or standby after people is detected, recover to
State before homoiothermic.
Above-mentioned setting time t1Write from memory and be recognized as 30 minutes, setting time t2Write from memory and be recognized as 3 hours, user can pass through APP
(Application, application program) can arrange setting time t1With setting time t2, APP can also be by learning user simultaneously
Use habit intelligently sets t1And t2Value；User can also can arrange the adjustable model of temperature adjustment value and temperature by APP
Enclose；Further, when determining that air-conditioner is standby, can be made whether to need the detection of dedusting, if desired, then laggard in dedusting
Enter standby.
