| Abstract: | Lonworks predominant characteristics were introduced. Structure and functional principle of an intelligent node for monitoring poisonous gas based on Lonworks technology were illustrated. A detailed scheme for the node includes software design and hardware design was presented. Fuzzy reasoning method was appli.ed to temperature/humidity compensation for measuring the gaseous density, After jointly debugging,the node appears a very satisfactory performance in practice. It fulfils all anticipative requirements with reducing the costs of manufacture and increasing administrative efficiency significantly. |
