| Abstract: | Lonworks is one of the most popular fieldbus technology and its protocol (LonTalk) is encapsulated in Neuronchip. Functional principle and structure of an intelligent node are illustrated in this paper. This node is used for monitoring gasand Neuron is its kernel. A detailed scheme includes software design and electronic circuit design is presented. Fuzzy reasoningmethod is applied to Temperature/Humidity Compensation for measuring the gaseous density,so that the accuracy andreliability are promote significantly. The node embodies a very satisfactory performance inpractical monitoring system. |
