Table 1
Fig. 5 is disclosed when processing unit 14 receives the equipment of instruction first of man-machine interface transmission for the switching of main equipment refers to
When making, the equivalent circuit diagram of the circuit diagram shown in Fig. 4.When processing unit 14 receives the equipment of instruction first of man-machine interface transmission
For main equipment switching command when, processing unit 14 control power supply pin position so that Scalar_GPIO6 is high potential, Scalar_
GPIO1 is high potential, and Scalar_GPIO2 is low potential, and Scalar_GPIO3 is high potential, and Scalar_GPIO4 is low potential.
Because Scalar_GPIO6 is high potential, Q1 conductings；Because Scalar_GPIO1 is high potential, Scalar_GPIO2 is low electricity
Gesture, Scalar_GPIO3 is high potential, and Scalar_GPIO4 is low potential, can obtain as shown in Figure 5 etc. according to above-mentioned table 1
Effect circuit diagram, wherein, the second equipment is connected with the communication of display device 1 and is closed, and establishes display device 1 and the
The communication connection of one equipment, and then cause that the first equipment is main equipment.
Fig. 6 is disclosed when processing unit 14 receives the equipment of instruction first of man-machine interface transmission for the switching of slave unit refers to
When making, the equivalent circuit diagram of the circuit diagram shown in Fig. 4.When processing unit 14 receives the equipment of instruction first of man-machine interface transmission
For slave unit switching command when, processing unit 14 control power supply pin position so that Scalar_GPIO6 is low potential, Scalar_
GPIO1 is low potential, and Scalar_GPIO2 is low potential, and Scalar_GPIO3 is low potential, and Scalar_GPIO4 is low potential.
Because Scalar_GPIO6 is low potential, Q1 is not turned on；Because Scalar_GPIO1 is low potential, Scalar_GPIO2 is low electricity
Gesture, Scalar_GPIO3 is low potential, and Scalar_GPIO4 is low potential, can obtain as shown in Figure 6 etc. according to above-mentioned table 1
Effect circuit diagram, wherein, the first equipment is connected with the communication of display device 1 and is closed, and sets up display device 1 and second
The communication connection of equipment, and then cause that the second equipment is main equipment.
To avoid electric current recharge to display device power-supply system, as shown in Fig. 4, Fig. 5 and Fig. 6, in drawing for USB chips J1
A diode D is connected between pin 1 and power supply, the positive pole of diode D is connected with+5V a power supply, the negative pole of diode D with draw
Pin 1 is connected, and the pressure drop specification of the diode is less than 0.25V.
If not having at least one the 3rd interfaces 16, in above-mentioned Fig. 4, remove USB chips U1 so that the first data
The data switching module 132 of handover module 131 and second is directly connected to, specifically, so that the pin of the first data switching module 131
D- and D+ connections corresponding with the pin D- and D+ of the second data switching module 132.
When the first equipment is main equipment, the control of processing unit 14 first power supply pin position and the second power supply pin position to be first
Equipment provides electric energy.Specifically, when the first equipment is main equipment, processing unit 14 controls the first power supply pin position and the second power supply
The potential of pin position to provide electric energy for the first equipment, and corresponding to the circuit diagram of above-mentioned Fig. 4 offers, processing unit 14 can control the
At least one of the one power supply pin power supply pin of position Scalar_GPIO6 and second position Scalar_GPIO5 power supply pin position is high potential
To cause that display device 1 provides electric energy for the first equipment, it is also possible to control the first power supply pin position Scalar_GPIO6 and second to supply
Electric pin position Scalar_GPIO5 causes display device 1 not for the first equipment provides electric energy for low potential.
General OTG connected modes, if running gear is main equipment, power supply supply is to be supplied to slave unit by running gear
End, but running gear uses battery supply finite capacity, if desired has additional power supply to originate, then need to increase USB Y profile and wires, by
External transformer or supply unit provide power supply.In the design, if running gear is main equipment, it is possible to use the electricity of display device
Source as running gear power source, without devices such as USB Y profile and wires and transformers, it is possible to decrease use cost.Work as action
When device is as OTG main equipments, can be provided by display device and be charged to running gear using power supply, reached OTG and charge together
The purpose of Shi Zuodong.
When computer and running gear all connect the interface in display device, if now user wishes that computer can be with
Running gear content is read, running gear can be switched to slave unit end by the design of the changeable ID pins that the present invention is provided,
Allow that computer reads the content in running gear as main equipment.
More larger device such as carry-on hard disc of the magnitude of current etc. is connected using running gear, because running gear is used as main equipment
When, the corresponding specification VBUS of pin 1 of J1 is to push away more than 8mA, it is thus possible to be not enough to promote carry-on hard disc, of the invention to set
Meter, when running gear is main equipment, display device can provide electric energy for running gear, and then running gear can be using display
The power supply of device is promoted, and then can read information kit in carry-on hard disc by running gear.
