Gateway for communication conversion between industrial Ethernet protocol and ONVIF protocol

Abstract

The invention discloses a gateway for communication conversion between an industrial Ethernet protocol and an ONVIF protocol. The gateway comprises a central controller and a peripheral circuit thereof; the central controller is in two-way connection with the peripheral circuit; a protocol transceiver is an optional device; when the protocol transceiver is not integrated in the central controller,the gateway comprises two protocol transceivers, and the central controller is in two-way connection with the industrial Ethernet and an ONVIF network through the two protocol transceivers; and whenthe protocol transceiver is integrated in the central controller, the gateway does not comprise the protocol transceiver, and the central controller is in two-way connection with the industrial Ethernet and the ONVIF network through own interfaces. The gateway disclosed by the invention can achieve a communication conversion function between multiple industrial Ethernet protocols and the ONVIF protocol just by loading different kinds of communication software without changing the hardware device of the gateway, so that the device cost can be reduced, and the device maintenance is facilitated.

Description

technical field [0001] The invention relates to a gateway for communication conversion between an industrial Ethernet protocol and an ONVIF (Open Network Video Interface Forum) protocol, belonging to the field of industrial automation control. Background technique [0002] Industrial Ethernet has the advantages of high real-time performance, fast transmission speed, and high reliability. It is the core technology to realize the interconnection and self-discipline coordination of production equipment, and then realize the intelligent factory. At present, there is no uniform standard for industrial Ethernet technology, including CC-Link IE Field, EtherCAT (Ethernet for Control and Automation Technology), EtherNet / IP (Ethernet Industrial Protocol), PROFINET, Modbus TCP (Transmission Control Protocol) and other communication protocols . Due to the existence of multiple industrial Ethernet protocols, different users often need to choose different hardware devices and manufacture...

AI Technical Summary

Problems solved by technology

However, because the ONVIF protocol cannot communicate with the industrial Ethernet protocol, the monitoring system is often isolated from the production equipment, and the interconnection and self-discipline coordination between the two cannot be realized.
