Based on above-mentioned mobile terminal hardware configuration and communications network system, each embodiment of the inventive method is proposed.
The embodiment of the present invention provides a kind of charging method, as shown in figure 3, this method can include：
Step 301, when terminal is connected with charging equipment by USB data line, determine the type of charging equipment.
Specifically, in the embodiment of the present invention, the type for determining charging equipment can be realized by terminal, i.e., terminal determines
The type of charging equipment.Terminal in the present invention can be mobile terminal, can be preferably to need to connect by USB data line
The mobile intelligent terminal to be charged.
Mobile terminal refers to the equipment that can be used on the move, and broad sense is said including mobile phone, notebook, tablet personal computer,
Even include vehicle-mounted computer.But refer in most cases mobile phone or with a variety of application functions smart mobile phone and
Tablet personal computer.As network and technology are towards the development in more and more broadband direction, Mobile Communication Industry will move towards real
The mobile message epoch.On the other hand, as the rapid development of integrated circuit technique, the disposal ability of mobile terminal have had
Powerful disposal ability, mobile terminal are changed into an integrated information processing platform from simple call instrument.This is also to shifting
Dynamic terminal adds broader development space.Mobile terminal is existing several with Mobile Communication Development as simple communication equipment
The history of 10 years.Mobile intelligent terminal is almost changed into the crucial entrance of Internet service between a flash and main innovation is put down
Platform, new media, ecommerce and information service platform, Internet resources, mobile network resource and environmental interaction resource are most
The strategy system of important pivot, its operating system and processor chips even as current whole information and communication technology (ICT) industry is high
Point.Mobile intelligent terminal can be referred to as intelligent terminal, and mobile intelligent terminal possesses access the Internet capability, generally carries various
Operating system, various functions can be customized according to user's request.Common intelligent terminal includes mobile intelligent terminal, vehicle-mounted in life
Intelligent terminal, intelligent television, wearable device etc..
Specifically, as shown in figure 4, when terminal and charging equipment be connected by USB data line carry out charge protocol communication when,
Terminal obtains the charging communication information, extracts charging equipment type information from the charging communication information, is believed according to charging equipment type
Breath determines the type of charging equipment.
Wherein, the type of charging equipment can include wall charger, i.e. terminal passes through USB data line and wall charger
Connection, it can be understood as, terminal is by wall charger directly in connection power source charges；The type of charging equipment can include
USB charge, i.e., terminal is connected with another electronic equipment by USB data line and charged, for example, mobile phone be connected with computer into
Row charging etc., i.e., terminal is not that charging is connected with charger.
Here, USB (USB, Universal Serial Bus) data wire is used for computer and external equipment
It is connected and communicate with, it can also be used to the charging of mobile phone and the connection with outside.Popular says, for transmitting data and charging.USB is
A kind of conventional PC interfaces, only 4 lines, two power supplys, two signals, four lines are 1- power supplys respectively, 2- data, 3- data,
4- power supplys, distribution color alignment mode is red white green black for from left to right, corresponds to 1,2,3,4 pins respectively.
The corresponding USB power source of red, indicates VCC, Power, 5V, 5VSB printed words；
The corresponding USB data line (negative) of white, indicates DATA-, USBD-, PD-, USBDT+；
The corresponding USB data line (just) of green, indicates DATA+, USBD+, PD+, USBDT+；
Black corresponds to ground wire, indicates GND, Ground.
Step 302, when the type of charging equipment is wall charger, the enabled terminals after first preset time that is delayed
Positive and negative signal shift switch.
Wherein, the positive and negative signal shift switch of enabled terminals includes：The data positive signal of USB data line and wall are charged
Device positive pole is connected, and the data negative signal of USB data line is connected with wall charger negative pole.
Here, the first preset time is less than the positive and negative signal shift switch of the enabled wall charger of wall charger delay
Second preset time.
Wherein, wall charger can be understood as power supply adaptor (Power adapter), power supply adaptor be it is small-sized just
Take the power supply conversion equipment of formula electronic equipment and electronic apparatus, typically by shell, transformer, inductance, electric capacity, control IC,
The components such as pcb board form, and its operation principle is converted to direct current output by exchange input；It can be divided into Direct Plug-In by connected mode
And Table top type.
Specifically, when the type for the charging equipment that terminal determines to be connected with itself is wall charger, mobile terminal CPU exists
It is delayed after 128ms and enabled mobile terminal DP_DM is switched into switch, data wire DP signals is connected with charger positive pole Vbus, number
It is connected according to line DM signals with charger negative pole GND.After switching is completed, charger continues according to the adjustment of communication protocol content most
Corresponding charging scheme, such as 9V2A, 9V3A etc..
Optionally, it is determined that after the type of charging equipment, in addition to：
When the type of charging equipment is not wall charger, will connect terminal USB data line data positive signal with
The data positive signal connection of the charge management module of terminal, the data negative signals and terminal of the USB data line of terminal will be connected
The data negative signal connection of charge management module.
Here, judging the type of charging equipment can not include for wall charger concrete scene：Charging equipment type is
USB charges, wall charger part and mobile terminal disconnection etc..
Specifically, if charging equipment type charges for USB, DP, DM existing connected mode, i.e. wall charger are kept
DP, DM of end USB data line are connected with DP, DM interface of charger micro-control module；The DP of mobile terminal side USB data line,
