On-line monitoring platform and database for indoor air quality and ventilation system performance of residential buildings

Develops a multi-sensor array on-line monitoring platform for residential indoor environmental parameters and ventilation system performance and a MySQL database, which can not only store hundreds of millions of long-term monitoring time-series data (LMTD), household information data and research data, but also manage them in a relational manner. Improves a bunch of algorithms to filter LMTD outliers and eliminate LMTD deviations, as well as algorithm selecting mechanisms to maximize the effectiveness of LMTD preprocessing.
