Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only the present invention's part embodiment, rather than whole embodiment.Based on the embodiment in the present invention, those of ordinary skills, not making the every other embodiment obtaining under creative work prerequisite, belong to the scope of protection of the invention.
Refer to Fig. 1, the schematic flow sheet of a kind of fault detection method providing for the embodiment of the present invention, the method is applied to electronic equipment, this electronic equipment can, for being desktop computer, notebook computer, mobile phone, panel computer etc., be provided with socket on this electronic equipment, audio accessories is connected with electronic equipment by socket, in socket, be provided with socket part, in the time that audio accessories is inserted socket, the socket part in socket triggers and interrupts, and the method can comprise:
Step S101: whether the interruption that detects audio accessories insertion socket is triggered.
Wherein, acoustic component can be earphone, and this earphone can be three-section earphone, can be also four-part form earphone.Under normal circumstances, in the time that earphone inserts the socket on electronic equipment, can make the socket part generation mechanical action on socket, interrupt thereby trigger.
Step S102: in the time that the interruption of audio accessories insertion socket is triggered, detect the voltage at default sampling test point place.
Wherein, default sampling test point is the sampling test point on the sampling path forming in the time that audio accessories is inserted socket.
Exemplary, electronic equipment is mobile phone, acoustic component is four-part form earphone, the headset plug of four-part form earphone has L channel electrode, R channel electrode, grounding electrode and microphone electrode, is provided with ADC in electronic equipment, in the time that earphone inserts the receiver J-Horner on mobile phone, ADC pin is connected with microphone electrode by the first resistance, form sampling path, ADC measures the voltage at default sampling test point place, the voltage that this voltage is microphone.
In addition, for three-section earphone (headset plug of three-section earphone has L channel electrode, R channel electrode and grounding electrode), in the time that earphone inserts the receiver J-Horner on mobile phone, ADC pin is connected with grounding electrode, and the voltage that ADC measures is 0V.
Step S103: whether the voltage at the default sampling of judgement test point place is identical with the first predeterminated voltage.
Step S104: when the voltage at default sampling test point place when identical, is determined socket part fault with the first predeterminated voltage.
Equally take electronic equipment as mobile phone, acoustic component is that four-part form earphone is example, the first predeterminated voltage is the DC offset voltage of microphone, under normal circumstances, if earphone inserts mobile phone, mobile phone can detect and interrupt being triggered, and, the voltage that ADC measures is the second predeterminated voltage (non-DC offset voltage), and now, mobile phone detects that the interruption that earphone inserts is triggered, but, DC offset voltage (the DC offset voltage that the voltage that ADC measures is microphone that the voltage that ADC measures is microphone, show that earphone does not insert the receiver J-Horner on mobile phone), earphone does not insert the receiver J-Horner on mobile phone, and the interruption that earphone inserts is triggered, can determine on mobile phone that the socket part fault in receiver J-Horner (for example, socket part is loosening).
For three-section earphone, under normal circumstances, if earphone inserts the receiver J-Horner on mobile phone, mobile phone can detect and interrupt being triggered, and, the voltage that ADC measures is 0V, and now, mobile phone detects that the interruption that earphone inserts is triggered, but, the voltage that ADC measures is non-zero value, can determine the socket part fault in receiver J-Horner on mobile phone (for example, socket part is loosening).
The fault detection method that the embodiment of the present invention provides can also comprise: after definite socket fault, on the display unit of electronic equipment, show fault information, break down with prompting user socket part, like this, user just can place under repair to the socket part of electronic equipment learning after fault.
