Embodiment Construction

[0032] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0033] Five types of physical devices are defined in the "WIA-PA Specification": main control computer, gateway device, routing device, field device and handheld device.

[0034] ●The main control computer is a computer for operators, maintenance personnel and management personnel to interact with WIA-PA. It interacts downward with the WIA-PA network and upward with the management network;

[0035] The gateway device is responsible for connecting the WIA-PA network and other factory network devices;

[0036] ●Routing equipment is responsible for field equipment management and packet forwarding;

[0037] ●Field equipment is the equipment installed on the industrial site to connect or control the production process;

[0038] ●Handheld devices are used for configuration, firmware update and monitoring of device status.

[0039] Among them, the WIA-PA protocol...

Abstract

The invention discloses a method of generating a WIA-PA (Wireless networks for Industrial Automation-Process Automation) protocol test set based on an equipment life cycle Petri net, which particularly relates to the industrial wireless sensor network technology. In view of characteristics such as the equipment type, the topological structure and the protocol stack structure of a WIA-PA network, according to the equipment life cycle, a Petri net model is built, information such as the place, the change and the initialization condition of the model structure are analyzed and checked, a change happening sequence is generated, and a full life cycle test set with the adding process, the operation process and the leaving process as the main body is generated for the equipment finally. An effective testing method is provided for testing the coincidence degree between the developed WIA-PA equipment and a WIA-PA standard, and thus, interconnection and interoperation between WIA-PA equipment developed by different factories can be ensured.

Description

technical field [0001] The invention relates to the technical field of industrial wireless sensor networks, in particular to a method for generating a WIA-PA protocol test set based on a device life cycle Petri net. Background technique [0002] Industrial wireless network is a revolutionary technology to reduce the cost of industrial measurement and control system and expand the scope of application. Industrial wireless sensor network technology has changed the way the existing system control information is transmitted, and it is another hot technology in the field of industrial control after the field bus. The information transmission method based on wireless technology makes the measurement and control system have the advantages of low cost, easy use, and easy maintenance, and has broad application prospects in the field of industrial control. The current wireless network standards in the industrial field include the WirelessHART standard, the ISA100.11a standard and the...
