Abstract
The present invention provides a method for realizing data exchange between a PDA and a computer. The present invention sets the PDA in two work modes, namely a normal work mode and a portable and mobile storing equipment work mode. When the PDA is connected with the computer through a USB cable, when a USB driver is in the normal work mode, the PDA is connected with the computer through ACTIVE SYNC software, and data exchange is carried out. When the USB driver is in the portable and mobile storing equipment mode, the PDA is connected with the computer through the USB driver of portable and mobile storing equipment, and the portable and mobile storing equipment and the computer carry out the data exchange. The two work modes can be switched freely under the control of the user. The present invention is applied, the PDA can be conveniently used as the portable and mobile storing equipment, synchronous software is not needed to be arranged between the PDA and the computer, and the high speed data communication is realized by a USB port.
Description
Technical field
The present invention relates to the computer peripheral technical field, be meant a kind of method that realizes portable computer and intercomputer swap data especially.
Background technology
Along with evolution of embedded technology, the use amount of portable computer product is more and more, as with POCKET PC (PPC, Microsoft is at a kind of embedded OS of mobile device exploitation) be the portable computer of operating system, or be that the portable computer of operating system has obtained application widely with SMARTPHONE (Microsoft is at a kind of embedded OS of mobile device exploitation).
Existing portable computer is used following two kinds of methods and computing machine (PC) usually and is carried out exchanges data, and this computing machine can be that desktop computer also can be a notebook computer etc.
Method one: application of synchronized software (ACTIVE SYNC) is realized the exchanges data between portable computer and the PC.When using this method, as shown in Figure 1, link to each other by USB cable between the usb host side controller in USB client controller in the portable computer and the PC, and all ACTIVE SYNC must be installed on portable computer and the PC, under the control of ACTIVE SYNC, could realize the exchanges data between portable computer and the PC.
The defective of this method is: PC is last must to install ACTIVE SYNC synchronizing software, otherwise this method can't realize at all.
Method two: use the exchanges data between infrared port realization portable computer and the PC.Connect by infrared port between portable computer and the PC, and utilize infrared management software to realize exchanges data.
The defective of this method is: when the application infrared port carried out data transmission, the infrared port of portable computer and PC must keep aiming at, and transmission speed is slower, thereby uses inconvenience, can not satisfy the demand of modern society.
Summary of the invention
In view of this, the object of the present invention is to provide a kind of method that realizes portable computer and intercomputer swap data, make between portable computer and the computing machine conveniently swap data.
For achieving the above object, technical scheme of the present invention is achieved in that
A kind of method that realizes portable computer and intercomputer swap data, this method may further comprise the steps:
A, portable computer judge whether self links to each other with computing machine by USB cable, if, execution in step b then, otherwise repeated execution of steps a;
B, portable computer judge that self USB driver is current and whether be in normal mode of operation, if, execution in step c then, otherwise execution in step d;
C, carry out exchanges data with the identity and the computing machine of portable computer, and judge whether the user carries out mode switch, if, then control USB cable and computing machine and disconnect one predefined period, again with USB cable with after computing machine is connected again, execution in step a, otherwise, repeated execution of steps c;
D, portable computer connect by the USB driver and the computing machine of portable mobile storage device pattern, and after changing the attribute information of self, carry out exchanges data with the identity and the computing machine of portable mobile storage device.
Preferably, described steps d further comprises: portable computer judges whether the user carries out mode switch, if, after then controlling USB cable and computing machine and disconnecting and reconnect, execution in step a.
Preferably, the described method of carrying out exchanges data with the identity and the computing machine of portable computer of step c is: portable computer connects by ACTIVE SYNC and computing machine, and the attribute that self is set is the desired virtual serial port equipment of ACTIVE SYNC, and under the control of ACTIVE SYNC, carry out exchanges data with computing machine.
Preferably, the attribute information of the described change of steps d self is: the attribute information of self is set to mass-memory unit.
Preferably, described portable computer is with POCKET PC, or is the portable computer of operating system with SMARTPHONE.
The present invention is provided with portable computer two kinds of mode of operations, i.e. normal mode of operation and portable mobile storage device mode of operation.When portable computer linked to each other with computing machine by USB cable, if the USB driver is a normal mode of operation, promptly portable computer linked to each other with computing machine by ACTIVE SYNC software, then carries out normal exchanges data; If the USB driver is the portable mobile storage device pattern, be that portable computer connects by portable mobile storage device USB driver and computing machine, then this portable computer carries out exchanges data as portable mobile storage device and computing machine, and above-mentioned two kinds of mode of operations can be switched arbitrarily under user's control.Use the present invention, easily portable computer is used as a portable mobile storage device, make portable computer and intercomputer need not to install any synchronizing software, directly can realize data communication at a high speed by USB port.

Embodiment
For making purpose of the present invention, technical scheme and advantage clearer, below the present invention is described in further details again.
Thinking of the present invention is: when portable computer links to each other with computing machine by USB cable, judge self USB driver present located mode of operation, if normal mode of operation, then portable computer links to each other with computing machine by ACTIVE SYNC software, the line data of going forward side by side exchange, if portable moving hard disc mode of operation, then portable computer connects by the USB driver and the computing machine of existing portable mobile storage device pattern, and after changing the attribute information of self, carry out exchanges data as portable mobile storage device and computing machine.
Figure 2 shows that the system software block diagram of using portable computer of the present invention.The USB client controller of portable computer is controlled by the USB driver, and this USB driver is divided into normal mode of operation and portable mobile storage device mode of operation two parts, and accepts the system on upper strata and calling of application program.
Figure 3 shows that the workflow diagram of using portable computer of the present invention.
The above only is preferred embodiment of the present invention, and is in order to restriction the present invention, within the spirit and principles in the present invention not all, any modification of being done, is equal to replacement, improvement etc., all should be included within protection scope of the present invention.
