Following embodiment further illustrates the present invention in connection with above-mentioned accompanying drawing.
Embodiment
Consulting shown in Fig. 1, is the applied environment figure of power adjustment system 40 preferred embodiments of the present invention.This power adjustment system 40 is applied to portable electric device 1.This portable electric device 1 comprises display screen 10, range sensor 20 and receiver 30.Range sensor 20 is arranged in the groove of left side, right side or receiver 30 of receiver 30.In the present embodiment, range sensor 20 can be optical displacement sensor, linear proximity transducer, ultrasonic displacement sensor etc.
User opens after the call function of portable electric device 1, and range sensor 20 starts and carry out object detecting.In the present embodiment, the power output of range sensor 20 is adjustable.If range sensor 20 detects object while work with some power outputs, power adjustment system 40 reduces the power output of range sensor 20.If range sensor 20 does not detect object while work with described power output, the power output that power adjustment system 40 increases range sensor 20 is to expand the distance reconnaissance range of range sensor 20.
Consulting shown in Fig. 2, is the functional block diagram of power adjustment system 40 preferred embodiments of the present invention.This portable electric device 1 also comprises background light 50, memory 60 and processor 70.In addition, this portable electric device 1 also may comprise miscellaneous part, for example keyboard, make a video recording first-class.Power adjustment system 40 comprises module 41, output module 42, adjusting module 43 and control module 44 is set.Module 41-44 comprises computerization program command, and these computerization program command are stored in memory 60.Processor 70 is carried out these computerization program command, and the above-mentioned functions of power adjustment system 40 is provided.Below in conjunction with the concrete function of Fig. 3 specification module 41-44.
Consulting shown in Fig. 3, is the flow chart of power regulating method preferred embodiment of the present invention.
Arrange after end, module 41 is set the regulation rule of the acquiescence power output of setting and power output is stored in to memory 60.
Step S20, when portable electric device 1 starts call function, range sensor 20 starts, output module 42 output acquiescence power outputs.For example, output module 42 is exported the power output of 6w, and range sensor 20 carries out object detecting with the power output of 6w.As previously mentioned, suppose the detecting distance of range sensor 20 and the power output variation relation in direct ratio of range sensor 20, D=aP, and coefficient a=0.5cm/w, range sensor 20 can detect and the object of display screen 10 distances within the scope of 3cm.
Step S30, range sensor 20 for example judges, with present output power (described acquiescence power output) whether detect object.If judge with this acquiescence power output and do not detect object, perform step S40.If judge with this acquiescence output power detecting to object, perform step S50.
Step S40, adjusting module 43 increases the power output of range sensor 20 according to described regulation rule.For example, the power output of range sensor 20 is increased 2w by adjusting module 43, and the power output of range sensor 20 becomes 8w by 6w.Afterwards, flow process is returned to step S30.Range sensor 20 for example judges, with present output power (8w) whether detect object, if do not detect object, again increases the power output of 2w, and the power output of range sensor 20 reaches peak power output threshold values 10w, adjusts and finishes.
Step S50, adjusting module 43 reduces the power output of range sensor 20 according to described regulation rule.For example, the power output of range sensor 20 is reduced 2w by adjusting module 43, and the power output of range sensor 20 becomes 4w by 6w.
Step S60, control module 44 is closed the background light 50 of display screen 10, and locks display screen 10.The position that it is pointed out that step S50, S60 can be exchanged.
It should be noted last that, above embodiment is only unrestricted in order to technical scheme of the present invention to be described, although the present invention is had been described in detail with reference to above preferred embodiment, those of ordinary skill in the art is to be understood that, can modify or be equal to replacement technical scheme of the present invention, and not depart from the spirit and scope of technical solution of the present invention.
