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 ab

Example Embodiment

[0092] Embodiment 1. Take reading FLASH as an example to illustrate the device access method of the present invention. The business component first calls the read device interface of the user interface module. When calling, the call parameter specifies the name of the FLASH device (or partition name) to be read. Read address and length. The reading device interface of the user interface module sends a request to the operating system kernel through a system call or the operating system’s API. 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 read FLASH device purpose.

[0093] According to the present invention, since the device-related parts are concentrated in the drive adaptation of the device management module, various business components can be applied on different devices without modification, thereby increasing the portability of business components Reusability and reusabilit...

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...
