Abstract

The invention relates to data transmission in an instrument system, in particular to the hardware structure of a high-speed multi-link ring network system. It solves the problem that the parallel bus data transmission structure in the existing instrument system restricts the performance of the instrument system, including the ring network bus, the function module plug-in board with the function module circuit on the bus slot inserted in the ring network bus, and at least one path containing and The communication links of high-speed 2×2 analog crossbar switches with the same number of bus slots, the control module including programmable gate array FPGA and switch management circuit, the switches of the communication links are placed between the adjacent bus slots of the ring network bus in turn The chip selection end of each switch is connected to the output end of the switch management circuit; the ring network bus includes a status signal bus; the function module board is provided with a low-voltage differential signal transceiver connected to the function module circuit. The invention has the characteristics of simple hardware structure design, high transmission rate, high communication efficiency, high reliability, flexible working mode, easy expansion and saving hardware resources.

Description

technical field [0001] The invention relates to data transmission in an instrument system, in particular to a hardware structure of a high-speed multi-link ring network system capable of reliable and rapid data transmission applied to high-speed instruments. Background technique [0002] A large amount of data needs to be transmitted within the instrument system. Existing instrument systems mainly use parallel bus to achieve communication and data transmission within the system. However, with the increasing amount of data to be transmitted within the instrument system, the parallel bus data transmission structure is facing challenges, which has become a constraint on data transmission speed and reliability. The main bottleneck of system performance. How to transmit data reliably and quickly to make the system run stably and reliably has become a new problem within the instrument system. Contents of the invention [0003] In order to solve the problem that the existing pa...
