Embodiment Construction

[0011] The implementation of the present invention will be specifically described below with reference to the accompanying drawings and specific examples. like figure 1 Shown is the block diagram of the test system. The industrial wireless network protocol conformance test system includes a man-machine interface module, a conformance test module and an intelligent test analyzer. The man-machine interface module imports the Protocol Implementation Consistency Description (PICS) file and the Protocol Implementation Additional Description (PIXIT) file of the device under test;

[0012] The intelligent test analyzer integrates a full-channel data acquisition control module, an environment simulation control module, a test agent module, a data processing module, and multiple wireless data acquisition modules. The analyzer integrates the RF transmission and reception of test commands, the capture of full-channel synchronous wireless data information in the industrial wireless test...

Abstract

The invention provides a system and a method for testing the consistency of an industrial wireless network protocol for protection, relating to an industrial wireless network. The invention adopts a plurality of independent wireless data collecting modules to monitor all frequency points in network channels in real time, each wireless data collecting module respectively monitors one independent channel to accurately acquire all-frequency point data in the industrial wireless network in real time, the all-frequency point data are sent into consistency testing modules for determining the realization statement according to the protocol-realization consistency instruction files and the protocol-realization additional instruction file of tested equipment so that the all-frequency point data are tested, and then a test report is generated. The invention provides effective test system and method for equipment, systems and engineering for checking the industrial wireless network and provides guarantee for the product certification of industrial wireless network equipment and the equipment interconnection between different protocol realizations of different manufacturers.

Description

technical field [0001] The invention belongs to industrial wireless networks, in particular to an industrial wireless network protocol consistency testing technology. Background technique [0002] The current wireless network standards in the industrial field include Wireless HART standard, ISA100.11a standard and China's WIA-PA standard. These standards are described in natural language and involve many key technologies, such as channel hopping technology, scheduling technology, security mechanism, etc. Implementers' different understanding of the protocol will lead to different protocol implementations, and sometimes even wrong implementations. Therefore, strict consistency testing must be carried out on the protocol of the protocol implementer to detect the degree of compliance between the protocol implementation under test and the protocol specification. [0003] Existing protocol conformance testing methods are mainly divided into two categories: one is a conformance t...
