Detailed description of the invention
For making the purpose of the present invention, technical scheme and advantage clearer, clear and definite, develop simultaneously embodiment pair referring to the drawings
The present invention further describes.Should be appreciated that specific embodiment described herein, and need not only in order to explain the present invention
In limiting the present invention.
Referring to Fig. 3, Fig. 3 is that present invention mobile terminal based on Proximity Sensor reduction aerial radiation method is the most real
Execute the flow chart of example.Mobile terminal based on Proximity Sensor shown in Fig. 3 reduces aerial radiation method, including:
Step S100, it is operated in upper antenna when antenna system mobile terminal being detected, and mobile terminal is operated in voice call
During state, whether the Proximity Sensor on detection mobile terminal touch screen has response;
Step S200, when the Proximity Sensor on mobile terminal touch screen has response, the emission maximum merit of antenna in reduction
Rate.
The mobile terminal of the embodiment of the present invention illustrates as a example by mobile phone (4G cell phone), the antenna for mobile phone system of the present embodiment
System uses slot antenna design, realizes launching the switching of antenna by TAS algorithm.Handset antenna radiation SAR value exceeds standard and endangers
Groundwork environment to health is: operating handset takes phone when upper antenna with maximum transmission power.Such as Fig. 4 institute
Show, it is generally the case that the upper end of the touch screen 9 of mobile phone is both provided with Proximity Sensor 8, and the present invention is based on being arranged on touch screen
Whether the Proximity Sensor 8 of 9 upper ends, be operated in upper antenna by detection antenna system, and whether mobile phone is operated in voice and leads to
During speech phase, and combine the corresponding situation detecting Proximity Sensor 8, automatically reduce the maximum transmission power of upper antenna.
In the step s 100, when antenna system mobile phone being detected is operated in upper antenna, and operating handset is in voice call
During state, whether the Proximity Sensor on detection handset touch panel has response;Antenna system is operated in antenna, operating handset
It is the premise whether detection Proximity Sensor has response at voice call state, and antenna system is operated in antenna, mobile phone
It is operated in voice call state and Proximity Sensor has response to be the essential condition reducing the above maximum transmission power of antenna.
Further, described step S100 specifically includes:
Whether S110, the antenna system of detection mobile terminal are operated in antenna;When being embodied as, can be by detection aerial system
The control level of system DPDT switch judges whether antenna system is operated in antenna, such as, if pre-setting DPDT switch
Control level be that high level respective antenna is operated in antenna, control level is that low level respective antenna is operated in lower antenna,
Then when the control level detecting that antenna system DPDT switchs is high level, then judge that antenna system is operated in antenna, instead
Then judge antenna system be operated in lower antenna.Wherein high level could be arranged to 1.8V, and low level could be arranged to 0V.
S120, when the antenna system of mobile terminal is operated in upper antenna, detection mobile terminal be to be operated in voice call
State or data transmission state;When being embodied as, can detect that current phone is operated in voice and leads to by bottom layer application program
Speech phase or data transmission state, such as, by TelecomManager report situation to judge operating handset is at voice
Talking state, by ConnectivityManager TYPE_MOBILE report situation judge operating handset data pass
Defeated state.
S130, when mobile terminal is operated in voice call state, detection mobile terminal touch screen on closely sensing
Whether device has response.Proximity Sensor is used for the contact condition that real-time perception mobile phone is current, when detection has bar contact,
That is to say that Proximity Sensor responds when mobile phone receives calls near head.
Further, described step S110 can also be refined as:
S111, detection mobile terminal touch screen on whether have touch, when being, enter step S112;In the embodiment of the present invention
During middle enforcement, first having touch on detection touch screen is to confirm that mobile phone is currently at user and uses state, when mobile phone makes
When using state, just open whether automatic detection antenna system is operated in antenna, when mobile phone does not uses state user, then
It is not turned on detecting the function of antenna system, so can save the memory source of mobile phone.
Whether S112, the antenna system detecting mobile terminal at predetermined time intervals are operated in antenna.Implement in the present invention
When implementing in example, setting at predetermined time intervals is also based on saving the consideration of the memory source of mobile phone, it is generally the case that extremely short
Time service is in the voice call of upper antenna condition, and its radiation effect is the most small, it is not necessary that the most all detect,
And the scheduled time can be arranged according to user's request, such as, 10S can be set and detect once.
Certainly also certainly exist a kind of situation, detect operating handset at data transmission state, now, aerial radiation is from head
Portion farther out, affects less, it is not necessary to the maximum transmission power of antenna in reduction.Therefore, described step S130 also includes: work as movement
Terminal works, when data transmission state, terminates process.
In step s 200, when the Proximity Sensor on mobile terminal touch screen has response, in reduction, antenna is
Launch greatly power;In the specific implementation, when the Proximity Sensor on handset touch panel has response, illustrate that mobile phone is leaned on by user
Nearly head is receiving calls, and (Attention command is applied to terminal and sets the most just can to pass through AT command order
Connection between standby and PC application and communication) maximum transmission power of antenna in reduction.
In the specific implementation, in order to solve the antenna radiation to human body head, method according to the invention it is possible to by mobile phone
Antenna Operation state be divided into two kinds: head model and body model.Wherein, the working state of mobile phone such as table that Head model is corresponding
Shown in 1: need to meet a) antenna for mobile phone and be operated in antenna, b) operating handset is at voice voice status (voice call state), c)
Receive the response that TP sensor (Proximity Sensor on touch screen) sends.And the working state of mobile phone that Body model is corresponding
There are two kinds: 1, a) antenna for mobile phone is operated in antenna, and b) operating handset is at voice voice status, c) are not detected by TP(and touch
Screen) response of sensor;2, a) antenna for mobile phone is operated in antenna, b) operating handset at data data transmission state non-voice
State;
The working state of mobile phone that table 1. head model is corresponding with body model

When meeting the condition of head model, it is determined that current duty is that mobile phone is receiving calls near human body head, hands
Machine application end reduces maximum transmission power by AT command order, it is achieved reduce the antenna radiation to human body;When meeting
During the condition of body model, do not react, terminate process.
Therefore, the mobile terminal based on Proximity Sensor that the present invention provides reduces aerial radiation method, by when inspection
Measure when the antenna system of mobile terminal is operated in upper antenna, and when mobile terminal is operated in voice call state, according to low coverage
From the response condition of sensor, automatically reduce the maximum transmission power of upper antenna, thus reduce the antenna spoke to human body head
Penetrate, it is to avoid be detrimental to health.
