In the practical application, can set up suitable communication path according to the type of information to be transmitted, as, when the less common command information of between the communicator transinformation content, only need set up the UART path and can satisfy transmission, and have lower power consumption the less command information of transinformation requirement; When communicator needs data services, can set up UART path and USB path simultaneously, wherein, can utilize the UART path to carry out the transmission of the less command information of transinformation in the data traffic transmission process, utilize the USB path to carry out the transmission of the data message that transinformation is big in the data service, because the USB path has the higher data transfer rate, therefore, can effectively satisfy the needs of the data message transmission that amount of information is bigger in the data traffic transmission; When not needing data services information, the USB path can be turned off, effectively reduce the bigger power consumption that the USB path causes communicator.Simultaneously, the present embodiment communication means also can be according to the transinformation of information to be transmitted, set up UART path and/or USB path, so that the message transmission of less transinformation transmits with the UART path, reduction information transmits the electric energy that consumes, and when having big transinformation demand, utilize the USB path to carry out the transmission of big data on flows information, improve the efficient that data transmit, when not needing to transmit big data on flows information, can only keep the UART path, reduce the power consumption of communicator.

In the practical application, during the initialization of communicating by letter between first communicator and the second communication device, the UART path can only be set, the information of carrying out transmits.When needing the bigger data message of transinformation content, can set up the USB path again, realize the transmission of data message with the UART path, improve the transmission efficiency of data message.

As can be seen, the present embodiment communication means is according to the information type of information to be transmitted, set up the UART path, or USB path, or set up UART path and USB path simultaneously, can effectively satisfy the needs of various message transmission, be specially adapted to that transmission amount of information bigger data message and command information are all had the occasion that needs, the bigger problem of power consumption when effectively having avoided in the prior art the single USB path information of carrying out to transmit, the restriction of speed when perhaps single UART path carries out message transmission, can under the prerequisite that guarantees the data message transfer rate, effectively reduce the power consumption in the whole communication process, save a large amount of electric energy.

Fig. 2 is the schematic flow sheet of communication means embodiment two of the present invention.Present embodiment can be applicable to the communication between the different communication device, supposes to communicate between first communicator and second communication device, and particularly, as shown in Figure 2, this method can may further comprise the steps:

Step 201, first communicator are judged the information type of information to be transmitted, wherein said information type can be common command information, perhaps data traffic information, when if described information type is common command information, execution in step 202, otherwise described information type is a data traffic information, execution in step 203;

Step 202, first communicator are set up the UART path, promptly set up the UART path between first communicator and second communication device, can transmit execution in step 204 by the UART path information of carrying out between first communicator and the second communication device;

Step 203, first communicator are set up UART path and USB path, promptly between first communicator and second communication device, set up UART path and USB path simultaneously, wherein, described UART path is used for the command information of data services correspondence, and described USB path is used for the data message of data services correspondence;

Step 204, first communicator and second communication device transmit according to the communication path of setting up between them information of carrying out.

In the present embodiment communication means, first communicator can be according to the information type of its needs transmission information, sets up the communication path between itself and the second communication device, can be the UART path, perhaps UART path and USB path.Particularly,, then can only set up the UART path, make the communication of winning between communicator and the second communication device message transmission based on UART if first communicator only transmits common command information; When if first communicator needs data services information, can set up UART path and USB path simultaneously, wherein, can utilize the UART path to carry out the transmission of command information, utilize the USB path to carry out the transmission of data message, can effectively satisfy transmission needs the bigger data service of transinformation.
