Abstract

According to the invention, a TTP bus network time planning configuration method in an aviation safety key communication system is studied; the method capable of dynamically configuring the TTP bus communication network based on the VxWorks operating system is designed, time network planning of a TTP bus can be dynamically changed through an Ethernet interface, and dynamic reconstruction of multiple nodes in a safety-critical communication system is achieved. According to the invention, an embedded code generation technology based on a model, a communication scheduling table generation technology, a dynamic loading technology based on a VxWorks system and a TTP protocol data decoding technology are studied; a series of methods of network planning, model simulation, code generation and codedynamic loading of the TTP bus are provided, and the TTP bus is successfully applied to an aircraft power distribution system, so that the safety and reliability of the product are greatly improved.

Description

technical field [0001] The invention relates to the dynamic loading control of time division multiple access network configuration and belongs to the field of embedded computer control. Background technique [0002] The implementation method of dynamic loading of TTP bus configuration is to plan the TTP bus time network and generate the corresponding MEDL table through TTP-Plan and TTP-Build development tools, integrate the MEDL table with the product software, and then download the software image file to PowerPC through the Ethernet interface The controller runs. The original TTP bus time network planning method uses the configuration interface of the TTP-Plan and TTP-Build development tools to complete the configuration through complex and cumbersome operations. The loaded binary format makes software integration difficult and risky. Contents of the invention [0003] The purpose of the present invention is to realize one-click generation of loadable TTP bus network ME...
