Embodiment Construction

[0043] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0044] figure 1 It is a WIA-PA to TSN structure diagram. The industrial Internet of Things is mainly composed of a backbone network and a field wireless network, including four types of equipment: a TSN switch, which constitutes an industrial backbone network, and forwards data streams in order of priority; WIA-PA / TSN converter to realize the conversion between WIA-PA data flow and TSN data flow; WIA-PA router is responsible for forwarding field device data; WIA-PA field device is responsible for industrial field data collection and control information transmission; TSN can be used as the backbone network, It can also be used as a field network. According to different uses of TSN, it can be divided into three communication situations:

[0045] (1) As the backbone network, TSN is responsible for the forwarding of data streams; the on-site n...

Abstract

The invention relates to an industrial wireless WIA-PA network and time sensitive network conversion method and apparatus, and belongs to the technical field of industrial networks. The apparatus consists of a TSN switch, a WIA-PA/TSN converter, a WIA-PA router and a WIA-PA field device. In the method, the WIA-PA/TSN converter is designed, two manners of MAC address addressing and IPv6 address addressing are supported, the mapping between a WIA-PA data stream and a TSN data stream is completed, the support of a data transmission priority is maintained, and the protocol conversion and interconnection between WIA-PA and TSN are effectively achieved; and furthermore, the invention further provides a transmission delay guarantee method between the WIA-PA and the TSN, the data can arrive withina specified deadline by allocating communication resources such as transmission time slots and the like, so that the instantaneity and certainty of the transmission of the data between the WIA-PA/TSNis ensured.

Description

technical field [0001] The invention belongs to the technical field of industrial networks, and relates to a conversion method and device between an industrial wireless WIA-PA network and a time-sensitive network. Background technique [0002] Industrial Internet of Things applies Internet of Things technology to industrial sites, realizing the integration of industrial automation and informatization. In a factory network using IIoT technology, it usually consists of a backbone network and a field network. There are all kinds of data in the factory network, and some important data with strict time requirements must be transmitted within strict delay and reliability regulations, including important control and fault detection data. In the industrial Internet of Things constructed by various networks, when the data needs to be transmitted across the network, how to ensure the real-time and deterministic data transmission becomes a challenging problem. [0003] WIA-PA (Wirele...
