Embodiment Construction

[0030] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings; it should be understood that the preferred embodiments are only for illustrating the present invention, rather than limiting the protection scope of the present invention.

[0031] Such as figure 1 Implement the architecture for the WIA-PA / XML adapter, including the following parts: user application object module, application sublayer module and network layer module.

[0032] The application layer of the WIA-PA network is composed of multiple user application processes, and each user application process is composed of one or more user application objects. The WIA-PA standard stipulates that user application processes and user application objects can follow the definitions in GB / T19769 "Function Blocks for Industrial Process Measurement and Control Systems" and "Function Blocks for Process Control" defined in GB / T 21099, or they can be defin...

Abstract

The present invention relates to a WIA-PA / full-internet manufacturing network information service adapter and its implementation method. The adapter can connect the WIA-PA network and its equipment to a full-service network with the IPv6 protocol as the addressing method and the XMPP protocol as the transmission method. An interconnected manufacturing network. Its implementation method is to convert the user application object of WIA-PA into the XML description format defined by the Internet in the adapter; in the application sub-layer, the C / S, P / S and R / S communication The mode is converted to the corresponding transmission mode in XMPP; at the network layer, the network address of WIA‑PA is mapped to a standard IPv6 address, so that each device in the WIA‑PA network has a virtual IPv6 address, and the external network can pass through IPv6 addresses address WIA‑PA devices. The adapter realized by the invention is easy to integrate with the existing network, and effectively realizes the open interconnection between the WIA-PA network and the Internet.

Description

technical field [0001] The invention belongs to the technical field of industrial measurement and control networks, and relates to a WIA-PA / fully interconnected manufacturing network information service adapter and an implementation method. Background technique [0002] In recent years, industrial wireless networks have developed rapidly. The WIA-PA standard (Wireless Networks for Industrial Automation-Process Automation, industrial wireless network standard for industrial process automation) is an industrial wireless standard proposed by my country to meet the needs of industrial wireless technology and has independent intellectual property rights. WIA-PA's physical layer and MAC layer are fully compatible with IEEE802.15.4 protocol. As one of the three major international industrial wireless standards, the formulation of the WIA-PA standard enables my country to occupy a place in the field of industrial wireless. It is very meaningful to develop and support the applicatio...
