A New Design of Distributed and Smart Automatic Weather Station

Abstract:

Aiming at development and requirement of environmental monitoring, automatic weather station (AWS) must be more powerful and reliable. With distributed data acquisition nodes, new AWS extends and adds new sensors easily. Using protective power supply to each node, new system has high performance of lightning protection, which will not let system breakdown for any node crash. Three-stage automatic self-checking for node state is included, which makes failure diagnosis efficient. Data quality checking node is created in the new design. By databases and correlation models, it provides data self-checking functions for unattended AWS. Defects of old design such as fixed hardware configuration and centralized data acquisition are overcome. Flexibility and stability of AWS are improved, and data reliability of unattended AWS is improved.
