Embodiment Construction

[0021] Below in conjunction with accompanying drawing, the present invention will be further described:

[0022] The present invention will be further described in detail below in conjunction with the accompanying drawings. The interaction process between the gateway and the client is as follows: figure 2 shown.

[0023] 1. Service establishment: The client sends a service establishment request to the gateway, the gateway monitors and receives the request to confirm the connection, and the service is established. The present invention does not limit the communication mode between the gateway and the client.

[0024] 2. Service cancellation: the gateway actively cancels the service and the client actively cancels the service.

[0025] 1) The gateway actively cancels the service: the gateway does not want to continue to provide services for the client, it can interrupt the connection without notifying the client, and then release the communication resources related to the co...

Abstract

The invention requests protection of an XML-based WIA-PA gateway service method. Using this method, the WIA‑PA gateway can provide an XML service interface, use XML to describe the message and exchange network information with the client, and support service establishment, service cancellation, device list report, topology report, path selection, route change, and superframe change , link change, attribute acquisition, attribute configuration and data acquisition and other services, so that external clients can easily obtain and configure various information of the WIA‑PA network. The advantage of this service method is that the WIA-PA gateway adopts XML to describe the message to exchange network information with the client, provides a unified structured data service independent of a specific platform, and realizes cross-platform service and distributed information processing.

Description

technical field [0001] The invention belongs to the technical field of industrial wireless network communication, and in particular relates to an XML-based WIA-PA gateway service method. Background technique [0002] The WIA-PA standard is an industrial Internet of Things standard independently formulated by my country. It has officially become an IEC international standard and is used in wireless network systems for industrial process measurement, monitoring and control. The WIA-PA standard adopts a two-layer network topology combining star and Mesh. The first layer is a Mesh structure, mainly composed of gateway devices and routing devices; the second layer is a star structure, mainly composed of routing devices and field devices (or handheld devices). Therefore, in the WIA-PA network, the gateway is not only an important collection device, but also a bridge connecting the WIA-PA network and the external network. At present, most of the communication protocols between WI...
