As shown in Fig. 2 a kind of method for detecting mobile phone use state, employs above-mentioned detection circuit and detecting system,
Specifically include：
Using the voltage of the tie point of voltage check device detection resistance R1 and R2：
In the case of one kind in the embodiment of the present invention, when radio-frequency cable accesses radio-frequency cable socket, radio-frequency cable socket
Control radio-frequency cable detection switch open circuit, is now not turned between inductance L2 and L1, and electric current flows through electricity from voltage input end VDD
It is grounded after resistance R1 and R2.Now because a terminal voltage of R2 ground connection is relatively low, comparatively a terminal voltage of R2 connections R1 is higher,
Therefore it is higher in the voltage that R1 and R2 tie points are detected, the voltage conversion that will can be detected is high level signal and passes through electricity
Pressure detection means output.User can be by judge module, and the high level signal according to output judges now mobile phone transmitting-receiving letter
Number by radio-frequency cable realize.
When radio-frequency cable is extracted from radio-frequency cable socket, radio-frequency cable socket control radio-frequency cable detection switch connects
It is logical, now connected between inductance L2 and L1, because the resistance between inductance L2 and L1 is much smaller than resistance R2, therefore electric current is from voltage
Input VDD flows through resistance R1, and selects to be grounded after flowing through inductance L2, radio-frequency cable detection switch and inductance L1.Now by
Radio-frequency cable detection switch and inductance L1 are sequentially connected in series in inductance L2 and be grounded, and the impedance of inductance L2 and L1 can be ignored not
Meter, now one end of resistance R1 series inductances L2 is in close proximity to ground voltage, therefore the voltage that voltage check device is detected
Relatively low, the voltage conversion that will can be detected is low level signal and is exported by voltage check device.User can pass through
Judge module, the low level signal according to output judges the antenna for mobile phone that now mobile phone receiving and transmitting signal passes through itself.
It is of the invention in another case, when radio-frequency cable access radio-frequency cable socket when, radio-frequency cable socket control open
Close and connect, now voltage check device can export low level signal, user judges that now mobile phone receives and dispatches letter by judge module
Number by radio-frequency cable realize.
When radio-frequency cable is extracted from radio-frequency cable socket, socket controlling switch open circuit, now voltage check device meeting
Output high level signal, user judges that now mobile phone receiving and transmitting signal is realized by antenna for mobile phone by judge module.
Above-mentioned two situations can be exchanged with each other in practical operation according to selected switching device, i.e., according to original state
Under, when radio-frequency cable is accessed, switch determines the level of corresponding voltage check device output in open circuit or on-state
RST, and accessed according to level signal and corresponding cable/extraction state selects to be applicable embodiments of the invention described above
In one of which detection case.The detection process under the first detection case is illustrate only in Figure of description of the invention 2.
In these cases, mobile phone is in conduction mode（Connection radio-frequency cable）Or radiation mode（By its own antenna）Transmitting-receiving
Signal；When mobile phone receiving and transmitting signal under conduction mode, adjustment part accordingly reduces the transmission power of power amplifier module；When mobile phone exists
Under radiation mode during receiving and transmitting signal, adjustment part accordingly increases the transmission power of power amplifier module.
The above method is only used for detecting whether the mode of mobile phone receiving and transmitting signal, i.e. mobile phone receiving and transmitting signal have used mobile phone day
Line, and it is not intended to the performance of actually detected mobile phone receiving and transmitting signal.By outside device for detecting performance, can obtain at two kinds
Under transceiver mode（Connect the conduction mode and the radiation mode using antenna for mobile phone of radio-frequency cable）The performance number of receiving and transmitting signal
According to so that the performance data of testing mobile phone receiving and transmitting signal more three-dimensional.
In actual applications, can be by above-mentioned antenna for mobile phone use state detecting system and corresponding detection method and mobile phone
With reference to reach the purpose of adjustment mobile phone receiving and transmitting signal performance.The use shape of antenna for mobile phone is detected by said detecting system
State, then according to the different use states of antenna for mobile phone, is believed using the overall transmitting-receiving of the software module adjustment mobile phone of embedded in mobile phone
Number performance；I.e. radio-frequency cable access in the case of, use embedded in mobile phone including emitting performance parameter, receptivity parameter with
And a set of configuration parameter of power back-off parameter etc. adjusts the performance of mobile phone receiving and transmitting signal；In the case where radio-frequency cable is extracted,
The performance of mobile phone receiving and transmitting signal is adjusted using the another set of configuration parameter including above-mentioned parameter of embedded in mobile phone.Using detecting system
The use state of antenna for mobile phone is obtained, the built-in module of mobile phone can be allowed more targetedly to adjust the performance of mobile phone receiving and transmitting signal
Configuration.
