Description
Technical field
This utility model is related to the device that electronic equipment interfaces communication reduces power consumption.
Background technology
Application number 201410140964.6, the Chinese invention patent application of entitled " electronic system " disclose a kind of electronics
System, comprises the first electronic installation and second electronic device.First electronic installation comprises the first display unit and first and processes list
Unit.First processing units are in order to operate the first operating system.Second electronic device comprises second processing unit.Second processing unit
In order to operate the second operating system.First electronic installation and second electronic device operate alone the first operating system and second respectively
Operating system.When the first electronic installation and second electronic device are electrically connected with, the first operating system and the second operating system are tieed up
Hold its state, and be optionally shown in the first display unit.At present, similar electronic system have been obtained for relatively broad
Application, described electric connection, connected the most universal with interface.Two electronic equipments, are connected by interface, mutually carry out data
Transmission, is properly termed as interface communication.The electronic equipment being connected by interface, according to interface protocol, often divide into main equipment and
From equipment.
Two mobile terminals are connected by USB interface, are application modes more typically.The operation that mobile terminal uses at present
System mainly has two kinds, the IOS system of American apple company exploitation and ARIXTRA (Android) system increased income.IOS system is installed
The electronic equipment being managed, is properly termed as IOS system electronics (the Iphone mobile phone that for example American apple company produces)；
The electronic equipment that android system is managed is installed, is properly termed as android system electronic equipment.When IOS system electronic sets
Standby be connected by USB interface with other electronic equipments, other electronic equipments for main equipment when, IOS system electronics are often write from memory
Recognize from main equipment obtain certain electric current power for IOS system electronics and be IOS system electronics battery charging.Right
In USB2.0 interface, the upper limit of electric current is 500mA, and for USB3.0 interface, the upper limit of electric current is up to 900mA.In a lot of feelings
Under condition, such as main equipment is also mobile terminal, when particularly main equipment is in low battery, this acquisition of IOS system electronics
The behavior of electric current has very serious adverse effect for the normal operation of main equipment.In order to ensure basic data communication, to the greatest extent
It is likely to reduced the kwh loss of main equipment, need to take some restrictions on the master.Conventional restriction is to lead
Output power chip is increased on equipment, but the technical scheme increasing output power chip is extremely complex, cost is also relatively
High.
In description " background technology " part disclosure, contribute to skilled artisan understands that of the present utility model
Technical scheme, but should not think that these contents necessarily belong to prior art or common knowledge accordingly.
Utility model content
For the defect overcoming " background technology " part to be reflected, a kind of this utility model implementation of offer is simple, one-tenth
This cheap electronic equipment interfaces communication reduces the device of power consumption.
This device includes resistance and switch, and, on the power line of electronic equipment interfaces, switch in parallel is in resistance for resistant series
Two ends, switch can control whether resistance accesses power line.
Further, electronic equipment includes main equipment and from equipment, switchs as electrical switch, the control of primary device.
Further, resistance or switch as one or more (multiple refer to two or more).
Further, interface is USB interface, is IOS system electronics from equipment.
Further, main equipment is android system electronic equipment.
Further, the resistance of resistance is 50 ohm.
In technical solutions of the utility model, the word such as " inclusion " should understand according to open language mode.Art technology
Personnel pass through the content read this specification and can know with reference to prior art or common knowledge, no longer superfluous in this specification
State.
The electronic equipment interfaces communication that this utility model provides reduces the device of power consumption, is opened using very simple resistance
Close design, effectively limit main equipment and obtain the behavior of electric current from equipment to main equipment when equipment is connected by interface, fill
Point reduce the power consumption of main equipment it is ensured that the normal operation of main equipment.
Brief description
Fig. 1 is the interface connection diagram in specific embodiment.
Specific embodiment
Below embodiment of the present utility model is further illustrated.It should be noted that it is of the present utility model
Scope is not limited to described concrete technical scheme.Any technology essential factor in described concrete technical scheme is carried out
Technical scheme that identical or equivalent obtains or those skilled in the art on the basis of described concrete technical scheme not
The technical scheme being obtained with through creative work, all should be contemplated as falling within protection domain of the present utility model.
One IOS system electronics (such as Iphone mobile phone), by USB interface, (this sets with another electronic equipment
Standby can be android system electronic equipment, such as Android phone) connect.According to USB transport protocol, by USB interface
The equipment connecting can divide into main equipment (Host) and from equipment (Device).Interface connects as shown in figure 1, closing in this connection
In system, IOS system electronics are from equipment, and another electronic equipment is main equipment.
According to USB transport protocol, USB interface include power interface (interface 1 in VBUS, Fig. 1), interface of the ground wire (GND,
Interface 4 in Fig. 1) and two data-interfaces (interface 2 and 3 in D+ and D-, Fig. 1).Connect two power interfaces is electricity
Source line.One resistance (R1) of series connection on the power line, in the two ends of a resistance switch (SW1) in parallel.Generally resistance and switch
Respectively setting one, can be respectively provided with multiple if there are special circumstances resistance or switch.
If it will be seen from figure 1 that switch SW1 closure, resistance R1 is shorted, and is equivalently employed without accessing power line；And
When switch SW1 disconnects, resistance R1 has been accessed power line.Switch SW1 can control whether resistance R1 accesses power line.
Resistance R1 can play the effect of partial pressure.The electric current that IOS system electronics obtain is bigger, and the voltage at R1 two ends is got over
Height, the voltage being supplied to IOS system electronics is lower.When IOS system electronics detect voltage and reduce, can reduce
The electric current obtaining from main equipment, thus lower the electric current output of main equipment.R1 chooses different resistances, can control IOS system
Electronic equipment obtains the size of electric current from main equipment.For example, for Iphone mobile phone, when R1 is taken as 50 ohm, can from
The current control that main equipment obtains is in 7mA.
Switch SW1 can select electrical switch, and the control of primary device (is typically controlled by the main control chip of main equipment
System).So main equipment can decide whether to provide larger electric current to from equipment according to own situation completely, it is desirable to provide larger
Close SW1 during electric current, otherwise disconnect SW1.This control method is very simple, with low cost, and can realize real-time control.
Those skilled in the art, on the basis of concrete technical scheme described above, can construct its other party completely
Case.For example choose and there is the electronic equipment of different operating system and different interfaces, by the resistance of resistance, the position of switch and resistance
Value is adjusted correspondingly.Numerous to list herein.
