Abstract

The invention relates to the field of communication, and particularly discloses a TTP / C bus-based program downloading system, which comprises a TTP / C bus downloading device and a TTP / C bus network, and is characterized in that the TTP / C bus downloading device is in communication connection with the TTP / C bus network; the TTP / C bus downloading device is used for periodically sending a downloading instruction frame and sending a table program data packet and a host application program data packet after the TTP / C bus network enters a downloading state; and the TTP / C bus network can enter a downloading state after receiving the downloading instruction frame, and receives the table program data packet and the host application program data packet in the downloading state. The invention further discloses a program downloading method based on the TTP / C bus. According to the program downloading system based on the TTP / C bus, the safety of a distributed fault-tolerant real-time system based on the TTP / C bus can be improved.

Description

technical field [0001] The invention relates to the communication field, in particular to a TTP / C bus-based program downloading system and a TTP / C bus-based program downloading method. Background technique [0002] The time-triggered protocol (TTP) bus is a high-speed, masterless, dual-redundant fieldbus communication protocol for safety-critical embedded applications in the transportation industry. It has the characteristics of low cost and strong time determinism, and can be used by multiple In a distributed fault-tolerant real-time control system composed of nodes. TTP / C meets the requirements of the Society of Automotive Engineers (SAE) Class C automotive applications and has been included in the AS6003 standard. [0003] The TTP / C bus uses a time-triggered architecture (TTA). In a time-triggered architecture, the communication system autonomously decides when to exchange data according to a static schedule. The bus controller of each node needs a customized table pro...
