To solve the problems of false fire reporting caused by inefficient management or insufficient maintenance of firefighting facilities, research on internet-based real time fire monitoring and on-line data analysis is presented. The concept of Complex Event Processing is introduced into a remote firefighting security monitoring system. In the system, an event processing language, together with its engine (Esper), is used to illustrate the events of false fire reporting. As a result, the entire process including data stream processing from IOT, events and rules modeling, and on-line discrimination of false fire reporting, are demonstrated in the system.
