Abstract

The invention relates to the technical field of communication, in particular to a method and system for converting multi-channel parallel CAN into Ethernet. The method comprises the following steps: CAN bus communication is processed through a plurality of control chips, each CAN bus is connected with 20 monitoring nodes, the control chips adopt SPI interfaces to achieve CAN bus grid connection, aprogrammable logic device is selected to achieve three-way SPI grid connection design, and a parallel port bus is adopted at a data output end to communicate with an upper-level chip. According to the invention, 12 CAN buses are adopted to work in parallel, there is no product capable of collecting the CAN buses at the same time on the market, all data is processed at a board level, and the efficiency is very high; data are transmitted upwards, are transmitted upwards through 125kbps CAN, 4Mbps SPI and 30Mbps parallel ports and finally converge into the Ethernet, the bottom layer CAN transmission rate is the bottleneck of the speed, and the upper layer protocol conversion does not influence the transmission efficiency of data streams.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and system for converting multi-channel parallel CAN to Ethernet. Background technique [0002] Industrial sites often use bus devices for networking communication, rather than the Ethernet commonly used by ordinary users. In the bus network, the CAN bus network is a common structure. CAN (Controller Area Network) was originally a communication protocol for automotive circuits, but it is now widely used in various automation equipment due to its reliability. In the CAN bus network structure, the device communication mode is multi-master mode: all devices are connected to the same bus, and all devices can send messages when idle (compared to master-slave mode, only specific hosts can send messages and apply for reply) . When it is applied to the detection system, the CAN communication module is generally installed on the detection equipment. After the detection ...
