Multi level hazard detection system

摘要

A multi level hazard detection system for home residents or owners or service providers that want to efficiently monitor and detect numerous common hazards in houses, offices or industrial structures. Hazards that may be dangerous their health or to the structural integrity of their houses, offices and industrial structures and all appliances and systems that are of these structures such as heating and cooling systems, pipes and more. By detecting hazards in advance, residents home owners and service providers can better protect their property. The multi level hazard detection system generally includes Single or Multi Sensor Device (170) that can be based on Low Power Communication Module (110), A Monitor and Control Device (140) which can be a mobile phone, desktop or laptop computer, an Analytic Server (150) and Relay Dongle (160).

主权项

1. A system comprising:
an analytics server that is arranged to: process detection signals generated from an acoustic sensor that is configured to sense chirp sound signals generated by a hazardous animal to search for an existence of the hazardous animal; and generate information relating to the existence of the hazardous animal; wherein the analytics server is configured to process the detection signals by calculating an attribute of a certain frequency component of a group of detection signals obtained by the acoustic sensor during a time window; wherein a certain frequency range of the detection signals is characteristic of the chirp sound signals generated by the hazardous animal; and wherein the analytics server is arranged to
calculate for each point of time out of multiple points in time of the time window, a sum of amplitudes of spectral components of the detection signals within the certain frequency range thereby providing multiple sums associated with the multiple points in time; andprocess the multiple sums to search for a signature comprising a pattern of sums that is the characteristic of the chirp sound signals generated by the hazardous animal to indicate the existence of the hazardous animal.
