Embodiment Construction
[0038] The technical features of the present invention will be described in detail below in conjunction with the embodiments and accompanying drawings.
[0039] see figure 2 , figure 2 Shown is a schematic structural diagram of the fast switching device of the present invention. A fast switching device 200 is provided in the information system 100 . In the fast switching device 200 , a storage module 201 , a query module 202 , a loading module 203 , and an acquisition module 205 are provided, and an unloading module 204 may also be provided.
[0040] Wherein, the storage module 201 is used for storing drivers of various input and output devices. That is, the system specifies a path for storing the drive, and the path (storage module) specified by each system may be different, but it is unique in the same system.
[0041] When the I / O device needs to be switched, for example, when the I / O device is plugged into the information system 100, the query module 202 in the quick...

The invention discloses a method of rapidly switching input and output device and its equipment. The method includes the processes as follows: step1, designates the only path in an information system where stores input and output devices' drivers; step2, when switching an input and output device, the information system searches the input and output device's driver in the path, and the input and output device's name matches with the input and output device's driver; if the input and output device's driver exits, execute step3; if it doesn't exit, the input and output device will be loaded to the information system. The effect of the invention is that it's simple, universal and high efficiency, the volume of system is small, the speed of system is rapid, input and output devices support is many and its treatment is simple. And needn't to increase system volume or system cost to increase its speed, solute deficiencies of traditional methods.
Description
technical field [0001] The present invention relates to a method and a device for an information system to process external devices, and more specifically, the present invention relates to a method and a device for an information system to quickly switch input and output devices. Background technique [0002] With the development of technology and the continuous improvement of people's requirements for system functions, more and more input and output devices are connected to the information system, and in different occasions, the user's demand for input and output devices is changing, so information is needed The system provides switching methods for input and output devices. [0003] One method is to pre-integrate the drivers for various input and output devices in the system, open all the drivers of the input and output devices when the system starts, and wait for the switching of the input and output devices. The disadvantages of this method are: [0004] 1. The system ...
