The invention provides a time-triggered protocol network planning method and system for an aviation power supply system, and a storage medium. The network architecture adopts a hardware-level dual-redundancy design, each communication node is provided with two independent TTP physical interfaces and corresponding TTP daughter cards, and the TTP physical interfaces and the corresponding TTP daughter cards are respectively accessed to a TTP A network and a TTP B network which are logically independent, so that channel-level fault isolation is realized. The planning method comprises the following steps: classifying messages according to power supply system services and defining a transmission period; initializing a cluster and setting time parameters such as a TDMA period and a cluster period; packaging the messages with consistent periods and reserving extension bits in a data structure; and calculating the time slot capacity based on the transmission rate, the node number and the TDMA period, and generating a deterministic message scheduling table. According to the method, high communication reliability is guaranteed through dual-network redundancy, the real-time requirement of various messages such as control and alarm is met through systematic scheduling, the expandability of the network is improved by reserving expansion bits, and the method is suitable for an aviation power supply system with strict communication performance requirements.

The application provides a time-triggered protocol network planning method, system and storage medium for an aviation power supply system. The network architecture adopts a hardware-level dual-redundancy design, each communication node is configured with two independent TTP physical interfaces and corresponding TTP subcards, and is connected to logically independent TTP A network and TTP B network respectively, so that channel-level fault isolation is realized. The planning method comprises the following steps: classifying messages according to power supply system services and defining transmission periods; initializing a cluster and setting time parameters such as a TDMA period and a cluster period; packing messages with consistent periods and reserving extension bits in a data structure; calculating time slot capacity based on transmission rate, node number and TDMA period, and generating a deterministic message scheduling table. The application guarantees high communication reliability through dual-network redundancy, meets the real-time requirements of various messages such as control and alarm through systematic scheduling, improves the scalability of the network through reserved extension bits, and is suitable for aviation power supply systems with strict communication performance requirements.

The invention provides a node simulation and monitoring system and method based on a time-triggered protocol, electronic equipment, a medium and a program product. The system comprises a node module, a message module and an interactive interface module. The node module is used for defining and simulating a plurality of specific nodes in the TTP network; the message module is used for managing a data structure transmitted by the TTP network and comprises a message packet and a message parameter; the interactive interface module is constructed based on a Qt framework and provides a graphical interface for node selection, message classification selection, parameter input / display and performance index visualization. According to the invention, flexible simulation of TTP network nodes and deep monitoring and performance analysis of network data can be supported at the same time, the problems of single function, poor interactivity and insufficient expansibility in the prior art are solved, and the development and test efficiency and user experience of the TTP network are remarkably improved.
