Multi-sensor information fusion-based wireless fire alarm system

Abstract

The invention relates to a multi-sensor information fusion-based wireless fire alarm system. The system comprises an industrial personal computer, a wireless transmission unit and a control unit, wherein the wireless transmission unit is used for connecting the industrial personal computer with the control unit; the control unit comprises a monitoring server, an analog-digital converter, an active low-pass filter and a plurality of data sensors; the multiple data sensors are connected with the monitoring server through the respective active low-pass filter and analog-digital converter respectively; the monitoring server, on one hand, is used for receiving data of the analog-digital converter, and on the other hand, is used for analyzing and processing acquired information by using a fuzzy reasoning algorithm-based multi-sensor information fusion technology and performing judgment processing on the acquired information according to a fusion database and an expert knowledge base; previously recorded data sets acquired by the multiple data sensors are stored in the fusion data base; different fuzzy reasoning rules corresponding to different application scenes are stored in the expert knowledge base. The occurrence of a fire disaster can be accurately and quickly judged.

Description

technical field [0001] The invention relates to the technical field of automatic control, in particular to a wireless fire alarm system based on multi-sensor information fusion. Background technique [0002] As the accuracy and reliability required by the fire alarm system are getting higher and higher, the common type of fire detection and alarm system can no longer meet the demand, and the alarm system with single index monitoring often produces false alarms, which brings a lot of inconvenience to production and life. . Using multiple sensors to comprehensively collect various abnormal information generated by fire, and using multi-sensor information fusion technology to process the fire information collected by sensors can greatly improve the reliability of the entire alarm monitoring system. Multiple monitoring indicators require multiple sensors to collect information, but multiple sensors bring a sharp increase in information, and it is difficult to formulate a reason...

AI Technical Summary

Problems solved by technology

In the traditional method, the information collected by each sensor is processed separately and in isolation, which will not only increase the processing workload, but also cut off the information connection between the sensors, and lose the information characteristics contained in the organic combination of information, resulting in information waste of resources
