Abstract
A monitoring system comprises a floor covering with a sheet-type pressure sensor and a sensor control unit. The latter includes an ADC for providing a digital raw signal, a microcontroller configured to carry out data extraction by signal processing of the digital raw signal and generating a digital processed signal having a lower digital bandwidth than the digital raw signal, and a communications module connected to or integrated within the microcontroller so as to receive the digital processed signal. The communications module is configured to establish data communication with one or more database servers and to transmit the extracted data to the one or more database servers.
Claims20
A monitoring system, comprising
- a floor covering having installed therein or thereunder a sheet-type pressure sensor;
- a sensor control unit connected to said sheet-type pressure sensor, including
- an analog-to-digital converter for converting analog signals provided by said pressure sensor into a digital raw signal,
- a microcontroller connected to said analog-to-digital converter for receiving said digital raw signal, said microcontroller being configured to carry out data extraction by signal processing of said digital raw signal and generating a digital processed signal having a lower digital bandwidth than said digital raw signal, said digital processed signal carrying data extracted during the processing of said digital raw signal;
- a communications module connected to or integrated within said microcontroller so as to receive said digital processed signal, said communications module being configured to establish data communication with one or more database servers and to transmit said extracted data to said one or more database servers;
- wherein said sheet-type pressure sensor comprises a ferroelectret polymer film, comprising a cellular polymer film structure exhibiting piezoelectric properties, the ferroelectret polymer film being sandwiched between a first electrode layer and a second electrode layer;
- and
- wherein a first electrically insulating film is arranged on the second electrode and a second electrically insulating film is arranged between the first electrode and a shield electrode.
