Multi-source heterogeneous device protocol conversion method based on NC-Link

The invention discloses a multi-source heterogeneous device protocol conversion method based on NC-Link. The method comprises the following steps: acquiring a to-be-converted protocol data packet corresponding to a to-be-converted protocol; and converting the protocol data packet to be converted into an NC-Link protocol data packet according to the improved NC-Link protocol model, wherein the NC-Link protocol model after protocol conversion comprises a protocol data conversion relationship. According to the invention, the to-be-converted protocol data packet corresponding to the to-be-converted protocol is acquired, and the to-be-converted protocol data packet is converted into the NC-Link protocol data packet according to the improved NC-Link protocol model comprising the protocol data conversion relation, so that other protocol data packets are converted into the NC-Link protocol data packet, data loss is avoided, and the conversion efficiency is improved. And the interoperability between the protocols is i
