The communication connection of person.
In this example embodiment, will carry out specifically as a example by the mobile phone of Android operation system
Bright.With reference to shown in Fig. 2, described data transmission method can comprise the steps:
S11. the USB device list of described mobile terminal is obtained.
With reference to shown in Fig. 3, after mobile terminal starts application program, can first state
UsbManager object.UsbManager object is responsible for the class of USB device, Ke Yitong
Cross the example obtaining this object in respective code.At this apoplexy due to endogenous wind, can be by such as
" getDeviceList () " obtains the USB device list of described mobile terminal.
S12. detect whether described USB device list comprises predetermined identity mark PLC set
Standby.
The identity of PLC device described in this example embodiment can include supplier ID
And product ID (PID) (VID)；According to the regulation of USB, all USB devices
Dou You supplier VID and PID, therefore can distinguish different equipment by VID and PID.
Can each with in sequential loop more described USB device list by iterator DeviceIterator
The identity of equipment, when finding the PLC device comprising predetermined identity mark, can connect
To this PLC device, but when not finding the PLC device comprising predetermined identity mark, then return not
Equipment to be connected.
S13. obtain after described PLC device being detected the COM1 of described PLC device with
And obtain the communication node of described COM1.
Described PLC device comprises one or more COM1 (Interface), each communication ends
Mouth comprises again one or more communication node (Endpoint) and is used for and described mobile terminal number
According to transmission.In this example embodiment, such as, can be returned by " getInterfaceCount () "
The COM1 quantity of described PLC device, and obtain institute by " getInterface (int index) "
State the COM1 of PLC device one, and it is logical to obtain this by " getEndpointCount () "
The number of nodes of letter port, and obtain this COM1 by " getEndpoint (int index) "
One communication node.Additionally, general communication node Endpoint be divided into InEndpoint and
OutEndpoint, obtain which kind of communication node can be according to concrete equipment depending on.
S14. open USB device, carried out data transmission by the described communication node obtained.
Shown in Fig. 3, it may be judged whether have the authority accessing described PLC device, example
As, above-mentioned application program can be judged whether by " hasPermission (UsbDevice device) "
There is the authority accessing described PCL equipment；When judging the authority not having to access, then need to obtain
Access the authority of described PLC device.When judging the authority having access, then can be by such as
" openDevice (UsbDevice device) " opens described PLC device, in order to described PLC
Equipment sending data or from described PLC device receive data.In this example embodiment, can
