Method for collecting data, sensor and supply network

A method for collecting data during operation of a local sensor in a supply network for distributing a consumable, the method comprising:

• providing the sensor with a measuring element, with radio communication capability and a memory;
• providing elementary measuring units with the measuring element of the sensor, the elementary measuring units corresponding to at least one physical or physico-chemical variable or at least one physical or physico-chemical parameter, and forming raw measurement data;
• in order to determine a measurement resolution of the sensor, determining conditions for generating time stamps in advance using a correlation model;
• generating time stamps of successive raw measurement data in the sensor based on the correlation model;
• transmitting the time stamps via a wired connection and/or a radio connection, whereupon the raw measurement data acquired by the measuring element are reconstructed and evaluated based on the time stamps using the correlation model;
• and
• dynamically and temporally changing conditions for generating time stamps within a framework of the correlation model by a data collector and/or a head end, the data collector and/or the head-end system stipulating or dynamically changing the conditions for generating the time stamps and transmitting the conditions to the sensor;
• and
• carrying out a new data transmission by transmitting a message or a telegram as soon as the following condition is met:
• reaching a predefined quantity of the time stamps since a previous transmission.
