System according to the present invention is very little with respect to the existing system volume, and the cost of change in design is few.Be used for supporting that meaning according to the minimum on the electronic equipment 1 of solution of the present invention only is that memory 8 at electronic equipment 1 has increased application data set 10 or structure 101, for example, comprise structured descriptor 10a and string descriptor 10c.If structured descriptor is in the standard usb protocol, then electronic equipment can be handled other descriptor, and no longer need to increase the prescribed coding support that is used for charger protocol, and support that can the ignore option order in some functional descriptions symbol.The selected part of charger protocol then must write some coding certainly to support these parts if desired.Optional charger commands can provide functional, as reading charged state in the slave unit, and can provide the power consumption above 500mA in order to charge quickly.
If adopt USB to come regulation communication protocol, then can utilize microcontroller to realize charging device with Embedded USB main frame.Can easily realize various functions like this according to charging device of the present invention.
Under the situation that adopts USB interface, the present invention allows electronic equipment to use USB Type B, small-sized Type B or the small-sized AB type connector of standard, and allows the user to use standard cable.This is more favourable with respect to the special connector that use is used for the USB charging cable, and the shortcoming that is used for the special connector of USB charging cable is to have increased processing cost, may increase needed space, and the user is produced inconvenience.
The present invention allows to use the electronic device of standard in equipment, and with respect to the charger according to prior art, only needs very a spot of electronic device that appends to charging device.In addition, charger can standardization, and uses in the mode of plurality of devices, allows large-scale production to reduce cost.
Except the top advantage of mentioning, under situation, utilize the problem that can avoid some appointment according to system of the present invention by USB standard code communication protocol, these problems can produce when being connected to charger on the electronic equipment.In order to illustrate that this point has provided following Example.With reference to electronic equipment 1 is connected to this situation on the external electronic unit, provide USB to be used as the situation of communication protocol standard below:
Consistency equipment need be followed electric power regulation given in the USB standard.These regulations can be summarized in following some: although main frame (external electronic unit 4a) provides a certain amount of electric power on Vbus pin 5 (Fig. 1 #5), standard allows main frame to follow the electric power amount that certain principle changes to be provided.If equipment is not followed these principles, just may cause system to break down.For example, may trigger the overcurrent protection in the host machine part, host machine part is not worked.Another example may be violated the power supply design limit of system, thereby prevents that locking system is waken up from halted state.
Specification defined when the equipment physical connection is to main frame below these equipment states:
Additional: equipment physics appends on the main frame, but Vbus is not powered.Adopt 4 USB lines, equipment does not need to distinguish this state and physics disconnects connection status; But this equipment may have the mode of some non-regulation detects this connection status.
Power supply: the equipment affix, Vbus is effective, but also is not reset.
Acquiescence: the equipment affix, Vbus is effective, and equipment has been reset at least once; But because last time, this equipment was reset, it also is not endowed nonzero address.
Addressing: the equipment affix, Vbus is effective, and equipment has been reset at least once; Equipment has been endowed nonzero address, but this equipment also is not endowed non-zero configuration value.
Configuration: the equipment affix, Vbus is effective, and equipment has been reset at least once; Equipment has been endowed nonzero address, and equipment has been endowed non-zero configuration value.
Suspend: equipment is in a kind of in (power supply, acquiescence, addressing or configuration) state recently, but does not have at least 3 milliseconds of bus activities.Short of business, equipment just keep this halted state.When business recovery, equipment turns back to its preceding a kind of state.
Utilize electrical method, have Vbus by detecting with respect to ground, it is in power supply state Equipment Inspection.By Vbus at first is provided, check the specific voltage on the each point that will become D+ and D-then, main frame detects the existence of equipment.Full speed and high-speed equipment are signaled annex by utilizing 1500 ohmic resistors to move D+ to Vbus.Low-speed device is signaled annex by utilizing 1500 ohmic resistors to move D-to Vbus.
Point out also in the specification that when switching, Vbus may offer equipment between additional and power supply state, but equipment is not signaled the main frame to this equipment institute affix, (that is, D+ or electric disconnection of D-pullup resistor or ground connection).The consistency process of the test needs equipment to make D+/D-be connected to Vbus in 100 milliseconds of times detecting Vbus.
USB consistency process of the test needs equipment to follow following principle:
1, initial, when equipment was connected to main frame, equipment entered power supply state.Equipment can extract the 100mA electric current and reach 100 milliseconds from Vbus; Equipment must enter " power supply " state then.
2, in " power supply ", " acquiescence " and " addressing " state, equipment can extract the 100mA electric current, but must identify the existence of bus traffic and the switching of " time-out " state of arriving.
3, in " configuration " state, equipment can extract as by corresponding to the specified as many electric power of electric power of power delivery scheme 9d, 10d among structured descriptor 9a, the 10a of the selected structure of main frame.
4, in " time-out " state, equipment can extract the electric current of up 500 μ A.
Now, can consider such a case, wherein, electronic equipment utilizes Vbus (Fig. 2 #5) to append on the charger according to prior art, thereby charger is connected to the standard USB socket on the equipment.This charger can not produce any business on usb bus.The USB part of equipment can not distinguishing charger and normal usb host.Therefore, necessary:
1, signals affix at cable in by 100 milliseconds of times of affix
2, the electric current that extracts is restricted to 100mA
3, correctly detect the time-out condition, and after being transformed into " power supply " state, in 3 milliseconds of times, power consumption is reduced to 500 micromicroamperes.Certainly, in case the power consumption of equipment is reduced to 500 micromicroamperes, it is invalid that charging will become.
Owing to the invention provides the solution that connects devices to charger by enumeration process described above, avoided this problem, and can charge to the battery pack of equipment efficiently.Under the situation that system according to the present invention uses, can provide electric current to come the accumulator plant in the electronic equipment is charged in USB interface up to 500mA.
It should be noted that electronic equipment 1 also can just will be connected to the electric storage battery of charging device, wherein charging device is a storage battery power supply.Therefore, in fact connector 3 will only be used for charging device 4b is appended on the electronic equipment 1.Therefore, have only a application data set can be stored in the electronic memory 8 that is provided with in the electronic equipment 1, thereby this application data set comprise the data according to the communication protocol request, is used to utilize charging device that accumulator plant is charged according to communication protocol.Alternative, two or more application data set according to communication protocol can be stored in the electronic memory 8, thereby application data sets has two data that comprise according to the communication protocol request at least, is used to utilize charging device that accumulator plant is charged.Therefore, each application data set can comprise the various functions that are used to be connected to the charger with specific standard.Like this, utilize same connector in all cases, in one case, has specific standard, for example consider charging current, some charger can be connected to this equipment, and other charger that has different size in other cases also can be connected to this equipment.
