In the past decade, industrial wireless technology and sensor technology have seen great development, such that the advantages of wireless sensor networks (WSN) in industrial applications have become increasingly obvious. Currently, the issue of how to design and build a stable and reliable industrial wireless sensor network remains an important research area in this field. In this paper, the operational information of each industrial wireless sensor network communication node is collected as a reliability test, and the information source is analyzed and evaluated. A reliability evaluation model is constructed based on factors affecting the reliability of industrial WSNs and a reliability assessment which uses traditional data analysis and mining methods. By using effective reliability evaluation strategies and methods, the reliability assessment's accuracy is guaranteed. As for the performance indicators of an industrial WSN's reliability, the impact of the protocol layer on network reliability was investigated. Based on this framework, the reliability index model and reliability evaluation method were studied.
