Title:
TSN COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/233708
Kind Code:
A1
Abstract:
[Problem] To achieve a TSN communication system which ensures real-time properties even in a Wi-Fi wireless communication area by using a TSN function, and ensures the time of a data update and access to a shared memory both over wired and Wi-Fi connections. [Solution] A TSN communication system 100 equipped with a TSN end controller 1 which has a TSN switch 4 which uses a TSN function, a shared memory 6 which has a memory region capable of external shared access, and a CPU core 5 for controlling the TSN switch and controlling access to the shared memory, said TSN communication system 100 being configured: so as to be further provided with a Wi-Fi module 61 which is built into the TSN end controller or is externally connected, and an IO device 11 which is Wi-Fi connected to the TSN end controller via a Wi-Fi module; and in a manner such that the time matching of the TSN function is effectively set by using an OS real-time package function, and a control register included in the TSN switch is set in a manner such that packet data outputted by the TSN end controller passes through the TSN switch at a prescribed timing.
