Method and system for collecting data supplied by sensors

A system for a remote reading of sensors installed in a given geographical area, the system comprising:

• a plurality of sensors, each having a device for storing and processing raw measured values for transmission functionally associated or integrated therewith;
• wherein each said sensor is configured for providing successive raw measurement data corresponding to timestamped elementary units of measurement of at least one physical or physico-chemical quantity or parameter supplied by said sensor;
• wherein the timestamped elementary units of measurement delivered by each said sensor correspond to a resolution or to a multiple of the resolution of a physical or physico-chemical quantity or parameter of said sensor;
• wherein each said sensor is configured with built-in radiofrequency communication or by way of a separate and remote module associated with said sensor;
• wherein said device for storing and processing of each said sensor or module includes a microcontroller configured to implement a compression of the raw measurement data and their preparation in a format suitable for a radiofrequency transmission according to a determined protocol, wherein each of the elementary units of measurement consists of a timestamped pulse, wherein the elementary units of measurement are able to precisely date the measurement data;
• wherein said device for storing and processing is configured for preparing compressed raw measurement data by formatting the measurement data into packets of a predetermined fixed size and transmitting the data in a repetitive and conditional manner if a predetermined time interval has elapsed and/or after accumulated data attain a size of a packet of accumulated compressed measurement data since a preceding transmission;
• an autonomous power supply for said sensor with said built-in radiofrequency communication of said module;
• and
• at least one remote processing installation, configured for acquiring, storing and using raw measurement data originating from said plurality of sensors of the geographical area concerned, and from other areas covering an overall territory associated with said installation;
• said at least one remote processing installation including hardware and software configured to implement, on the one hand, following decompression, a use of the received raw measurement data, for reconstruction of timing charts of the values associated with each of the sensors, and the performance of business functions and, on the other hand, a cumulative storage of the raw data.
