Performance analysis of a fail‑safe wireless communication architecture for IoT based fire alarm control panels

摘要

This study presents a fail-safe wireless communication architecture for Internet of Things based fire alarm control panels.In fire safety industry, one of the most important issues is to ensure the key information be delivered. A radio frequencywireless communication link is considered for enabling the fail-safe feature when the primary Internet of Things link isfailed. In this paper, the design of the wireless communication architecture is proposed, and the system hardware basedon customised micro-controller and wireless communication processors is implemented. In order to examine the performanceof the proposed wireless communication architecture, a long-term evaluation is designed and conducted in anindustrial warehouse, to demonstrate the information latency with parameter of round-trip time, and system reliabilitywith parameter of probability failure rate. The experimental results show that the proposed wireless communicationarchitecture could achieve the low latency and high reliability requirements and reduce the chance of key informationloss. With the multi-disciplinary findings discovered, the proposed wireless communication architecture is feasible tobe considered to use in future Internet of Things based fire safety products.
