Abstract

The invention describes a method for monitoring vibrations produced by an operating area, comprising the following steps: (E1): dividing an operating frequency range into a plurality of frequency sub-ranges; (E2): for each frequency sub-range, defining an associated vibration threshold; (E3): continuously acquiring vibration measurements produced by the operating area; (E4): periodically transmitting vibration data resulting from the vibration measurements, the vibration data being transmitted to a remote server (200) via an LPWAN network; (E5) detecting a vibration event corresponding to at least one vibration threshold being exceeded in the associated frequency sub-range; (E6): when a vibration event is detected, transmitting a warning to the remote server (200) via the LPWAN network.

Dependent claims

A method for monitoring vibrations produced by an area of operations, the method being implemented by means of reporting means comprising a mobile terminal and by means of a vibration monitoring sensor comprising a vibration sensor, a battery, a processing unit, a transmission unit of long-range low-consumption technology of a Low-Power Wide Area Network (LPWAN) type, said transmission unit comprising a transmitter module allowing transmissions via an LPWAN network, the method comprising the following steps:

(E1):
dividing an operating frequency range into several frequency sub-ranges;
(E2):
for each frequency sub-range, defining an associated vibration threshold;
(E3):
continuously acquiring vibration measurements, the vibrations being produced by the area of operations, by means of the vibration sensor;
(E4):
periodically transmitting, at a sending period (Tsending), vibration data from the vibration measurements, the vibration data being transmitted to a remote server via the LPWAN network, by means of the transmission unit;
(E5):
detecting a vibration event corresponding to at least one vibration measurements exceeding the vibration threshold associated to the frequency sub-range in which the vibration measurements is included, by means of the processing unit;
(E6):
when a vibration event is detected, transmitting an alert to the remote server via the LPWAN network, by means of the transmission unit;
transmitting a reporting of a vibration event by a user of the mobile terminal when the mobile terminal of the user is below a given distance threshold from the area of operations;
and
reporting a vibration event by a local resident, the reporting being carried out through the mobile terminal of the local resident, when the mobile terminal of the local resident is below the given distance threshold from the area of operations.
