Problems solved by technology
[0003] 1. The external system needs to load software data to each node in the internal system one by one, requiring human intervention to select different nodes, which is time-consuming and error-prone;
[0004] 2. The external system and the internal system adopt the traditional serial port loading method, which cannot meet the requirements in terms of loading speed for large quantities of data;
[0005] 3. There is no verification mechanism for serial port data loading, and the security is low

Embodiment Construction
[0028] Each module node under this method is divided into a first-level node and a second-level node according to different roles in system loading.
[0029] The first-level node is at the core of the entire system loading. Through information interaction with the external data loader, the data and supporting information required for system loading are obtained from the external data loader. At the same time, the first-level node communicates with the second-level node. Interaction, notify the secondary node to read the data that needs to be loaded from the data sharing storage area.
[0030] The secondary node is in a subordinate position in the loading of the entire system. Through information interaction with the primary node, the software data to be loaded is obtained from the data sharing storage area, and the software data is solidified to the designated location of the secondary node.
[0031] A kind of embodiment structural diagram in this method is as seen figure 1 A...

The invention relates to a software loading method of an avionics system. Two levels of nodes are divided in an internal system; nodes of highest level are defined as primary nodes; nodes of secondarily high level are defined as secondary nodes; a data sharing storage area is set in the primary nodes; batch files are transmitted to the primary nodes through an external data loader and are then distributed to the secondary nodes through the primary nodes; loading is achieved. The software loading method has the advantages that software can be loaded in batch for multiple nodes in the avionics system, the software in the avionics system can be upgraded by a user quickly and conveniently, loading efficiency of data software in the avionics system is greatly improved accordingly, development and maintenance costs are saved, and the method is of great significance to maintainability of the software in the avionics system.
Description
technical field [0001] The invention belongs to the application field of integrated avionics systems, and specifically relates to a software loading method of an avionics system. Background technique [0002] With the continuous improvement of the degree of integration of avionics systems, the scale of avionics system software is becoming larger and larger. The integrated avionics system is undoubtedly a software-intensive system. The realization of the functions of avionics subsystems is increasingly dependent on software. In order to upgrade and maintain the software in each subsystem in a timely manner, it is necessary for the external system to continuously load various software data to the internal system to meet the ever-changing system requirements. The existing external system loading method to the internal system mostly adopts serial port loading. Although it can meet the loading function requirements, there are still the following defects: [0003] 1. The external...
