Abstract
The invention discloses a detecting method and apparatus for a USB port type. The detecting method comprises the steps of when an inserted USB interface is detected, detecting the charging port type of the USB interface; when a detection stop condition is satisfied, stopping the detecting of the charging port type according to the detected charging port type; and when a re-detection condition is satisfied, re-detecting the charging port type once at predetermined intervals until the detection stop condition is satisfied according to the detected charging port type. According to the technical scheme, the re-detection condition is set in the charging process; when the re-detection condition is satisfied, the charging port type is detected periodically; therefore, the problem of wrong detection on the charging port type caused by negligence of a user or the aging of the connector of the USB data line is solved on the basis of sacrificing a quite short charging time; and in addition, the scheme is convenient to realize, and extra additional hardware cost is not required.
Description
Technical field
It relates to charging technique field, particularly relate to detection method and the device of USB port type.
Background technology
Along with the fast development of smart mobile phone, the performance of mobile phone is increasingly stronger, and the power consumption rate of battery also shows
Work accelerates, and people are more and more stronger for the demand of quick charge.
USB interface includes VBUS (voltage bus) pin, DP (Digital Positive, data are just)
Pin (also referred to as D+ pin), (also referred to as D-draws DM (Digital Minus, data minus) pin
Foot) and GND (Ground, ground wire) pin.In the related, DP pin and DM pin divide
Other and terminal built-in charging IC (Integrated Circuit, integrated circuit) is electrically connected with, and leads in terminal
Crossing in the case of USB interface is connected with charger, charging IC by DP pin and DM pin and fills
Electrical equipment communicates, it is achieved charging port type detection.
USB association is proposed USB BC1.2 specification to distinguish different charging port types, with fully profit
Charging rate is improved by the ability of charging port.BC1.2 specification briefly defines standard down port
(SDP), charging downlink port (CDP) and special charging port (DCP) three kinds are different types of
USB port.On the basis of BC1.2, high pass it is also proposed it quick charge standard QC2.0 and
QC3.0.If DCP supports QC2.0 or QC3.0 agreement, charging rate can be improved further.
BC1.2 specification after connection VBUS being detected, compulsive requirement detection D+ and D-this two
Whether individual data wire connects.Therefore according to BC1.2 specification, most equipment are all detecting
After VBUS connects, wait the regular hour, just start with DP and DM and detect USB port type.
If USB data line adapter is aging, or due to the carelessness of user, mobile phone may be caused to insert USB
It is slow that this process of data wire becomes comparison.Thus it is likely to result on mobile phone being responsible for the power supply of charging
Managing chip, in the case of DP and DM is not the most fully connected, has just started port type detection,
Therefore the port type of mistake is detected.Next will fill according to the USB port type of mistake
Electricity, have impact on charging rate.
