Abstract

The invention discloses a control method for data transmission in an industrial network, a device and equipment . The method comprises the following steps: setting a network device in the passive optical network and an industrial device in the industrial network to keep clock synchronization, wherein the network device comprises an optical line terminal and an optical network unit; dividing the uplink time slot period into an IRT channel in the optical line terminal, so as to align the IRT channel with the IRT channel in the data transmission period of the PROFINET bus standard; when the optical network unit receives IRT data sent by the industrial equipment, applying for a time slot for transmitting the IRT data from the optical line terminal so as to obtain a first fixed time slot allocated by the optical line terminal from an IRT channel contained in the uplink time slot period; and forwarding the IRT data from the industrial equipment to the optical line terminal through the first fixed time slot in the optical network unit. According to the embodiment of the invention, the forwarding time delay of the IRT data in the industrial network can be reduced.

Description

technical field [0001] The present application relates to the technical field of industrial Internet, and in particular to a control method, device, device, and computer-readable storage medium for data transmission in an industrial network. Background technique [0002] Passive Optical Network (PON) is an access network using optical fiber, which refers to the optical fiber distribution network between the Optical Line Terminal (OLT) and the Optical Network Unit (ONU). It does not use any electronic equipment with power supply between the optical line terminal and the optical network unit. It has the advantages of high reliability, high bandwidth, and low network construction cost, and has gradually been widely used in various industries. After introducing the passive optical network technology in the industrial network, the control distance in the industrial network can be extended, but the passive optical network equipment will additionally introduce data forwarding delay...
