Abstract

The invention discloses a multi-node master-slave network system. The system comprises a network controller node and a plurality of network terminal nodes, wherein each network controller node comprises hardware, software and a buffer area, when the network controller node serves as a sending end and the network terminal nodes serve as a receiving end, in the network controller node, whether readable data exist in the buffer area or not is judged in one time slot, and after the time slot is ended, when the readable data exist in the buffer area, the data are read and sent, a first flag bit nc_buf_flow of a message block state word in the message completion information queue block is set to be 1 when no data needs to be sent in the buffer area; and after the first flag bit nc_buf_flow of the message block status word in the message completion information queue block is set to be 1, the software is also used for reading the message completion information queue block.

Description

technical field [0001] The present application relates to the field of multi-node communication systems, in particular to a multi-node master-slave network system. Background technique [0002] Data sending and receiving flow control, that is, the flow control technology in the process of data sending and receiving, referred to as data flow control, is used to realize that the frequency of data transmission can be controlled by the user during the message operation process of master-slave communication protocols such as FC-AE-1553 Control according to actual needs. This article starts with the interactive process of FC-AE-1553 data sending and receiving, compares and analyzes the technical status and patented technical solutions, and summarizes the characteristics and application value of this patented technology. [0003] The FC-AE-1553 network is a high-bandwidth, low-latency, and highly reliable optical fiber communication bus protocol. Its protocol is formulated by the ...
