Problems solved by technology

[0004] However, since the interface provided by the above-mentioned logical device driver directly depends on the device driver architecture of the operating system or directly replaces some functions of the operating system, the business components generated by using the interface provided by the logical device driver are in different architectures. There is a big difference in the implementation of different operating systems, which is not conducive to the transplantation of business components
In addition, the interface provided by the above-mentioned logical device driver is also related to the specific device driver unit. If the interface is used, it must follow the specifications defined by the device driver unit. Therefore, it is not convenient to use the interface provided by the logical device driver to generate Reuse of device drivers
Furthermore, the interface provided by the above logical device driver defines an access control command interface for each type of device, resulting in too many APIs (Application Programming Interface, application programming interface)

Embodiment 1

[0092] Embodiment 1, take reading FLASH as an example to illustrate the device access method of the present invention, business component calls the device reading interface of user interface module at first, when calling, calls parameter and specifies the FLASH device name (or partition name) that will read, Read address, length. The device reading interface of the user interface module sends a request to the operating system kernel through the system call or the API of the operating system. The operating system calls the device adaptation according to the user's parameters, and then the device adaptation uses the drive unit to realize the reading of the FLASH device. Purpose.

[0093] According to the present invention, since the parts related to the equipment are concentrated in the driver adaptation of the equipment management module, various business components can be applied on different equipment without modification, thus increasing the portability of the business compo...

Abstract

A method for realizing device access interface includes obtaining unit driving information of different units and forming unit adaptive information according to obtained driving information then utilizing formed adaptive information to update system call information in operation system, packaging unit access interface used for calling on different units based on updated system call information. The unit access system and its access method are also disclosed.

Description

technical field [0001] The invention relates to a device management technology, in particular to a module and method for realizing a device access interface, a device access system and a device access method. Background technique [0002] With the development of communication technology, not only the types of devices are increasing, but also the functions of devices are increasing. In order to realize these functions of devices, business application software needs to access devices through device access interfaces. Due to the different types of equipment, different characteristics, and running on different hardware and software platforms, it is difficult to transplant business application software, the code reuse rate is low, and the product styles of different manufacturers are not the same. Therefore, a cross-platform, highly flexible and scalable device control and management architecture is needed in order to reduce the difficulty of transplanting business application so...
