Description
[Ji Intraoperative field]
The invention relates to a kind of operation mode judging system and method, more detailed, relate to a kind of tool USB (universal serial bus) (Universal Serial Bus that is used to; When USB) electronic installation of connecting interface is connected to the data processing equipment of tool USB (universal serial bus) connectivity port through this USB (universal serial bus) connecting interface, determine the operation mode judging system and the method for the operating mode between this electronic installation and this data processing equipment.
[Bei Jing Ji Intraoperative]
Along with the progress of science and technology now, electronic product is also constantly weeded out the old and bring forth the new, also just therefore, make electronic product become indispensable sci-tech product in the daily life already, and many electronic products are for asking highly compatible and high data rate, and the connecting interface of itself and data processing equipment such as computing machine adopts USB (universal serial bus) (Universal Serial Bus mostly; Be designated hereinafter simply as USB).
But the connecting interface of USB has plug and play and can supply the advantage of the electronic installation running required electric power that uses the USB connecting interface, but the power supply capacity of the chip of USB connecting interface is limited, and the usb connecting port that is set on the computing machine now also reaches more than 4 port to 8 ports, so only setting the maximum output current of each port according to the power supply standard of USB connecting interface, computer system is about 500 milliamperes (mA), preventing normally to be provided the electronic installation of electric power, and also can't carry out the facts of data transmission to use USB connecting interface because of the chip of USB connecting interface overload causes.
Use in the electronic installation of USB connecting interface, with the mobile phone is example, be present communication electronic product most favored by customers, the popularity rate of intelligent's hand one machine even two machines almost, and the conversation use amount of mobile phone is also along with teen-age communication custom is significantly improved, in addition, because the consumer improves gradually for functional requirement now, therefore, mobile phone not only has call function now, wherein, more comprise as functions such as MP3 play, takes a picture, records a video, listens to the radio programme; Again with personal digital assistant (Personal Digital Assistant; Be designated hereinafter simply as PDA) be example, the function of its tool is not also failed in mobile phone, even more comprised the function of satellite navigation (GPS), but, no matter electronic installation such as mobile phone or PDA is to need power source eventually, and because of the storage electric weight and the flying power of the rechargeable battery in those electronic installations limited really, so design of electronic products person visualizes a kind of way to take power, the charge function of this type of electronic installation is provided by acquisition electric power on the data processing equipment of the most normal use such as the computing machine, its advantage is need not carry charger, therefore use the mode of the charging cable of USB connecting interface just to become preferable solution, in addition, because the usb connecting port that is set on the computing machine can provide the electric current about about 500 milliamperes (mA), with respect to this type of electronic goods, promptly enough charge and meet the power supply standard of USB connecting interface.
Yet, the charging cable of existing USB connecting interface directly sees through the Vcc pin position of electronic installation mostly and charges, even some electronic installation has more saved the pin position except that Vcc and GND, and then also do not have tool and be connected the function of carrying out data transmission with computing machine, its design concept merely only inserts power supply, give no thought to the rated power supply electric current of USB connecting interface, therefore, if need being connected to carry out data transmission with computing machine, electronic installation then need use another transmission lines again, so cause inconvenience and waste in the use.
For solving the above problems, TaiWan, China is announced No. 479393 patent case and is just proposed a USB automatic charge device and a method of operating thereof, include a charger, an indicator, reach a charge controller, wherein, this indicator is in order to show the charged state of this charger, this charge controller makes the magnitude of current of bus power source maintain the portative maximum current flow of a USB connecting interface specification, so that can reach the charge volume that has complete information and maximum load when charging with the communication cables of a USB connecting interface.
But; aforesaid patent case only utilize with computer interconnection to carry out charge function; and additionally provide the user to supervise interface and the safeguard measure that prevents to overcharge; yet; the user supervises interface and only utilizes software to supervise the situation of power source charges; and can't effectively judge online state and online pattern; and if device is in park mode (suspend mode) or not under the configuration mode (unconfigured mode); still have the communication cables output of electric current in a small amount via the USB connecting interface; this part is to know via the interface that supervises under the online mode, so this patent case still can't effectively judge whether to be in the pattern of charging.
Therefore, how providing a kind of technical scheme that solves foregoing problems, is present problem demanding prompt solution.
[summary of the invention]
