A time-triggered protocol bus network online loading configuration and monitoring method

Abstract

The invention provides an online loading configuration and monitoring method for a time triggered protocol (TTP) bus network. The method is realized by adoption of an online loading configuration and monitoring system. The system comprises a computer (1), a TTP bus monitor (2) and a TTP bus network (3). The configuring and monitoring method comprises a loading and configuring step and a monitoring step. By means of the online loading configuration and monitoring method for the TTP bus network provided by the invention, the problems in the existing TTP bus network loading configuration and monitoring method are solved; the system development and verification efficiency is increased; manpower and material resources in the development process are saved; and simultaneously, the method integrates loading and monitoring into a whole, so that the system development and verification cost is greatly reduced.

Description

technical field [0001] The invention belongs to the field of communication, and in particular relates to a time-triggered protocol (TTP) bus network online loading configuration and monitoring method. Background technique [0002] The time-triggered protocol (TTP) bus is a high-speed, masterless, multi-end point transmission dual-channel field bus communication protocol bus, which has the characteristics of small comprehensive cost, strict deterministic communication and low life cycle cost, and can be used for Intelligent control systems provide distributed safety-critical, hard real-time computing and networking applications. In aviation or other safety-critical fields, the time-triggered protocol (TTP) bus is more and more widely used, and the Society of Automotive Engineers (SAE) has included the TTP bus in the AS6003 standard. [0003] The TTP bus uses a Time Division Multiple Access (TDMA) scheduling scheme for communication. TDMA cycles have the same length, and one...

Problems solved by technology

[0005] The invention proposes a time-triggered protocol (TTP) bus network online loading configuration and monitoring method, the method simultaneously realizes the time-triggered protocol (TTP) bus network MEDL table online loading configuration and bus monitoring, and solves the problem of separate loading in the current loading method Time-consuming, labor-intensive and error-prone problems, and at the same time, no additional design will be added during system development, so system development costs and failure modes will not be increased. At the same time, the bus monitoring realized by this method can completely monitor the entire bus network, and will Information such as the node number and time slot number corresponding to the data is displayed in real time, which solves the problems existing in other monitoring methods and improves the efficiency of system development and verification
