Embodiment Construction

[0045] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0046] First give the following instructions:

[0047] Note 1: Domain manager: manages the waveform component resources in the domain, registers and cancels the device manager, and is responsible for the creation of waveform applications and management of waveform functions.

[0048] Note 2: Device Manager: Responsible for the registration and deregistration of logical device resources in the domain, as well as the configuration and query of device attributes.

[0049]Note 3: Logical device: the software agent of a specific hardware device in SCA. The logical device implements the operation of the specific hardware interface through the hardware abstraction layer protocol, and the CF realizes the loading and unloading of the waveform application components on the specific hardware device and the configuration and query of attributes such as d...

Abstract

The invention discloses a software communication system structure of a dual-core framework, including upper management software, an adaptation layer module and two core frameworks, the core frameworkcomprises a domain manager and a device manager. the adaptation layer module performs the following steps: 1, when the software communication architecture is initialized, the adaptation layer module causes the domain managers and the device managers in the two core frameworks to have the same attributes, and judges the master-standby relationship of the two core frameworks according to the defaultconditions; 2. In that run process of the software communication architecture, when the adaptation layer module receives the application instruction installation, the application uninstallation instruction and device registration instruction of the upper layer management software, the corresponding operation is completed by calling the operation interface in the main core framework through the CORBA middleware, the domain manager in the backup core framework and the attributes of the device manager are updated, and the device logout result is returned to the upper management software. Thirdly, when the adaptation layer module receives the feedback result of the domain manager or device manager failure of the main core framework, the backup core framework is enabled.

Description

technical field [0001] The invention relates to a software communication system structure of a dual-core framework. When the main core framework fails, it switches to the standby core framework to execute the function of the original main core framework. Background technique [0002] SCA divides the software / hardware structure through the object-oriented method, establishes an open system standard, provides a software radio development framework that has nothing to do with the specific implementation, and ensures the portability, reconfigurability and scalability of software and hardware. An SCA-based software platform includes an operating environment and one or more waveform applications. According to the definition of the SCA standard, the operating environment includes the operating system, CORBA middleware, core framework and logical devices. [0003] The operating system is a computer program that manages and controls computer hardware and software resources. It is th...
