A redundant solution for collective residences inflammable gas leaking monitoring using ultra-low power transmission system and automatic control

Abstract

Because the gas monitoring domestic use is important issue for all involved actors, many researchers and designers have approached this field. After a detailed state-of-arts analysis, in this paper deep research has been devoted for information flow and communication link design. Two important criteria have been established for information linking between collective residences and a general monitoring system, then ultra-low power Wi-Fi, and Zigbee-based devices have been used for experiments. Then, because of many unpredicted risk situations, a fuzzy model of gas leak risk evaluation has been designed. The used core device was a microcontroller with major roles: fuzzy/defuzzy processes, packet data link operating and processing, and regulatory user interface. Timed communication events and sets of action rules have been tested on the implemented system.
