Satellite-borne driving framework design method based on real-time operating system

Abstract

The invention discloses a satellite-borne drive framework design method based on a real-time operating system. The method comprises the following steps: 1, classifying satellite-borne external equipment; 2, defining a user-level equipment structure body for the drive of each kind of equipment; 3, defining an operation interface of the satellite-borne external equipment; 4, associating the interface defined by the user with a structural body pointer defined by an operating system; 5, compiling the driver into an independent module, ending with. Ko, and realizing separation from the kernel; 6, starting a registered device driver by teh embedded operating system, and starting an application program and registering a specific device; 7, adding a middleware layer on the operating system, uniformly managing equipment, and providing a uniform hardware calling interface to the outside; and 8, periodically monitoring each external device. According to the method, the external equipment drivingmodule can be separated from the kernel, decoupling is realized, and great expandability and convenience are achieved.

Description

technical field [0001] The invention relates to the technical field of on-board embedded software, in particular to a design method of an on-board drive frame based on a real-time operating system. Background technique [0002] One of the main functions of the embedded operating system is the management of platform hardware device resources. With the change of satellite informatization and intelligent mission requirements, the functions of the satellite-borne integrated electronic system are constantly upgraded, and the types and interfaces of external equipment are showing exponential growth. Utilizing the traditional on-board software development model for the development of integrated electronic system software, on the one hand, the performance of high-performance processors cannot be brought into full play, and on the other hand, the external device interfaces of the platform cannot be effectively managed and used. At the same time, under the traditional software develo...
