Abstract

A method and a device for processing and storing data generated in a fluid flow station, the data being read and put into a volatile memory allocated to a communicating module of the flow station. The data are analyzed according to predetermined relevancy criteria to select data corresponding to a type of event, and the selected data are analyzed according to a redundancy criterion to detect data having the same value during two successive readings. The data having a value unchanged in relation to the value of the previous reading are replaced by a mark and the data thereby compressed are stored in a non-volatile memory.

Claims

1. A method for processing and storing data generated in a fluid delivery station by a data processing platform, including a communication module, the method comprising:

reading the data and placing the data in a volatile memory assigned to the communicating module of the delivery station,

polling the delivery station periodically by the processing platform,

determining a window of time before beginning of an event having data sought for processing and storage, and

after beginning of the event, processing and storing only the data received during the window of time.

2. The method according to claim 1, including:

analyzing the data according to predetermined relevance criteria

selecting from the data only the data corresponding to a type of event,

analyzing the data selected according to a redundancy criterion to detect data having the same value during two successive readings of data,

replacing the data having a value that is unchanged with respect to the value of the data in the previous reading with a mark, thereby compressing the data, and

storing the data, after compressing in a non-volatile memory.

3. The method according to claim 1, including storing the data generated in the delivery station in the volatile memory assigned to the communicating module of the delivery station in the order in which the data are read.

4. The method according to claim 2, including storing the data, after compressing, in the non-volatile memory of the communicating module of the delivery station in the order in which the data are placed in the non-volatile memory.

5. The method according to claim 1, wherein the communicating module polls the delivery station approximately once per second.

6. The method according to claim 1, including reading and placing the data generated in the delivery station, in the volatile memory assigned to the module, with a frequency of approximately 1 Hz.

7. The method according to claim 1, including numbering the data generated in the delivery station by the module, for each response before being placed in the volatile memory.

8. A device for processing data generated in a fluid delivery station comprising:

means for reading the data generated, in a communicating module of the delivery station;

a volatile memory for storing the data read;

non-volatile memories storing selection criteria;

at least one comparator for selecting data according to predetermined relevance and redundancy criteria; and

a non-volatile memory storing the data selected.

9. The device according to claim 8, wherein the volatile memory for storing the data that have been read is organized as a queue register.

10. The device according to claim 8, wherein the non-volatile memory for storing data selected is organized as a queue register.

11. The device according to claim 9, wherein the non-volatile memory for storing the data selected is organized as a queue register.
