Embodiment 3
With reference to Fig. 4, it is shown that the flow chart of the detection method of another embodiment of the present invention.
On the basis of the mobile terminal described in embodiment three, the detection method being applied to mobile terminal is illustrated, tool
Body step is as follows:
Step 201, the state of monitoring Signal-controlled switch.
If step 202 described Signal-controlled switch Guan Bi, then the first signal that up-converter circuit sends is sequentially passed through the
One radio frequency connector, the second radio frequency connector being connected to described first radio frequency connector by external radio frequency line and radio frequency are cut
Change switch, and obtain secondary signal after being processed by Receiver Module.
Step 203, detection when the processor described radio frequency converting switch of extraction and described Receiver Module are properly functioning
The standard attribute value of each frequency band signals handled by circuit.
In the embodiment of the present invention, the standard attribute value of signal refers in the normal work of radio frequency converting switch and Receiver Module
Under work, the signal attribute value of the secondary signal obtained after Receiver Module processes.Wherein property value can include performance number,
Standard attribute value includes calibration power value.
When detecting radio frequency converting switch and Receiver Module is the most properly functioning, need Receiver Module is sent
The property value of a certain signal that receives of i.e. processor and standard attribute value corresponding to the signal frequency of this signal compare,
Determine that radio frequency converting switch and Receiver Module are the most properly functioning according to comparative result.Therefore when manufacturing testing circuit,
Need to obtain in advance the standard attribute value of different frequency range signal, and by the signal frequency range of signal and the corresponding relation of standard attribute value
Storage is within a processor.
Mobile terminal needs to carry out data before dispatching from the factory to be preset, and needs to use RF transceiver to enter the signal of different frequency
Row modulation, collects the signal power of each signal of up-converter circuit output, the signal power of the signal of up-converter circuit output
Size approximates the size of the signal power of each frequency band signals at the first radio frequency connector, therefore can also collect the first radio frequency
The size of the signal power of each radiofrequency signal at adapter.
The signal frequency range collected can include in radio communication the reception frequency range of conventional high/medium/low frequency range, need through
When the signal frequency range of Receiver Module detection can include, frequency-division section and frequency division frequency range, specifically can include low frequency: GSM900
Receive (925-960MHz), GSM850 receives (869-896MHz) etc.；Intermediate frequency: B1 receives (2110-2170MHz), B2 receives
(1930-1990MHz), B3 receives (1805-1880MHz), B34 receives (2010-2025MHz), B39 receives (1880-
1920MHz) etc.；High frequency: B40 receives (2300-2400MHz), B41 receives (2496-2690MHz) etc..
Before the operation conditions of detection radio frequency converting switch and Receiver Module, need from memorizer, extract inspection
The standard attribute value of each frequency band signals handled by slowdown monitoring circuit, compares use for follow-up.
Step 204, according to the signal frequency range of described secondary signal received, search standard corresponding to described secondary signal and belong to
Property value.
After receiving the secondary signal that Receiver Module sends, obtain the signal frequency range of secondary signal.Foundation afterwards
The corresponding relation of the signal frequency range-standard attribute value of storage in memorizer, searches the mark corresponding to signal frequency of secondary signal
Quasi-property value.
When property value includes performance number, and standard attribute value includes calibration power value, the signal of secondary signal can be obtained
Frequency range and signal power value, afterwards according to the corresponding relation of the signal frequency range-calibration power value preset, search secondary signal
Calibration power value corresponding to signal frequency.
Step 205, according to the property value of described secondary signal and default standard attribute value, to described radio frequency converting switch
Judge with the ruuning situation of described Receiver Module.
After the standard attribute value finding correspondence, the property value of secondary signal and corresponding standard attribute value can be calculated
Difference；If the difference calculated is less than the difference threshold preset, then judge that radio frequency converting switch and Receiver Module are in
Normal operating condition；If the difference calculated is more than or equal to the difference threshold preset, then judge radio frequency converting switch and radio frequency reception
In module, at least one is in abnormal operational conditions.
In reality, the standard attribute value of unlike signal frequency range can be different, need before mobile terminal dispatches from the factory according to terminal
Self-inspection is collected statistics, and the standard attribute value such as B1 could be arranged to 50, and the standard attribute value of B2 could be arranged to 40, B3's
Standard attribute value could be arranged to 60.
Reception parameter within mobile terminal stores with offset, as a example by B1, when mobile terminal dispatches from the factory, passes through
The standard attribute value that self-test procedure obtains in predesigned compensation value i.e. the application is 50 (10 represent 1dB)；Compensate decision content i.e. difference
Threshold value is also to preset within a processor, and this value can be with sets itself, as being set to 100 (10 represent 1dB)；At process of self-test
In, detect when the signal power value of the secondary signal tested oneself in offset i.e. the application is 300, calculate and compensate difference=test oneself
Offset-predesigned compensation value=300-50=250, compensate difference more than compensate decision content, thus judge Receiver Module and
Radio frequency converting switch is abnormal.If in process of self-test, detect that offset of testing oneself is 80, then calculate and compensate difference=benefit of testing oneself
Repay value-predesigned compensation value=30, compensate difference less than compensating decision content, thus judge Receiver Module and radio frequency converting switch
Normally.
In the embodiment of the present invention, Receiver Module can include radio frequency reception path, low-noise amplifier, radio-frequency receiving-transmitting
Lower frequency changer circuit in device and second modem.First signal sequentially passes through radio frequency converting switch, radio frequency reception path, low
The process of noise amplifier, lower frequency changer circuit and second modem, obtains secondary signal, due to second modem,
Lower frequency changer circuit and low-noise amplifier are hardly damaged, and therefore can use the method described in the embodiment of the present invention, according to reception
Secondary signal the ruuning situation of radio frequency converting switch and radio frequency reception path is detected.
According to embodiments of the invention, the power that the first signal of up-converter circuit output is walked around in radiofrequency emitting module is put
Big device and radio-frequency transmissions path, be directly over the first radio frequency connector, by the of external radio frequency line and the first radio frequency connector
Two radio frequency connectors, radio frequency converting switch, and obtain secondary signal by Receiver Module after being processed, processor receives radio frequency
The secondary signal that processing module sends, and according to the secondary signal detection radio frequency converting switch received and Receiver Module
Ruuning situation, thus realize radio frequency converting switch and the self-inspection of Receiver Module, it is not necessary to use detecting instrument, reduce people
Power material resources cost.
