Embodiment
The invention provides a kind of human-machine interface control device and control method.For making object of the present invention, technical scheme and advantage clearly, clearly, developing simultaneously referring to accompanying drawing, the present invention is described in more detail for embodiment.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
Please refer to Fig. 1, human-machine interface control device provided by the invention is arranged in the terminal, and it comprises temperature detecting module 10, comparison module 20 and control module 30.Described temperature detecting module 10, comparison module 20, control module 30 connect successively.Described temperature detecting module 10 gathers a face temperature every Preset Time, and face temperature transition is become corresponding initial voltage signal.Comparison module 20 compares with the term of reference preset after carrying out amplifying voltage stabilizing process to described initial voltage signal, and control module 30 controls the secretly bright of man-machine interface backlight according to comparative result.
In the present embodiment, described man-machine interface and display screen.Described temperature detecting module 10 comprises the infrared temperature sensor 101 and output unit 102 that model is TS118-3.Described infrared temperature sensor 101 is arranged on the top, front of mobile terminal, and hand-held mobile terminal mistiming can be avoided to gather hand temperature affects backlight control by mistake.As shown in Figure 2, described infrared temperature sensor 101 is for Real-time Collection face temperature and convert corresponding initial voltage signal to, high to the induction precision of face temperature.Described output unit 102 is every Preset Time
export once current initial voltage signal Va, need data volume to be processed to reduce, save system cloud gray model power consumption.
The voltage signal exported based on temperature detecting module 10 is more weak, also needs to carry out respective handling to strengthen the stability of voltage signal before comparison module 20 compares.Then described comparison module 20 comprises amplifying unit 201, voltage regulation unit 202, voltage comparison unit 203 and distance detecting unit 204.Described amplifying unit 201 amplifies described initial voltage signal voltage signal, then after carrying out voltage regulation filtering process by voltage regulation unit 202 output voltage signal Vb in voltage comparison unit 203.Preset term of reference with reference voltage signal Vx ± threshold value (as 0.5V) for benchmark.
Described distance detecting unit 204 identifies the distance of face and display screen according to the voltage signal after amplification voltage stabilizing process, i.e. viewing distance Lb.Voltage signal Vb after actual acquisition process and the term of reference preset compare by voltage comparison unit 203, if voltage signal is less than term of reference, i.e. and Vb< (Vx-0.5V), the comparative result of output is low level L; If voltage signal is in term of reference, namely Vb is in (Vx ± 0.5V) scope, and the comparative result of output is the triangular wave TW of one-period; If voltage signal is greater than term of reference, i.e. Vb> (Vx+0.5V), the comparative result of output is high level H.
