Method and a system for enabling a wireless communication between a master unit and a sensor unit
First Claim
1. A method of enabling a wireless communication between a master unit and at least one sensor unit to be executed within a frame, the at least one sensor unit having a data sampling frequency for sampling one or more of its channels and for storing resulting samples in a buffer memory together with a corresponding sample sequence number, wherein the at least one sensor unit is adapted to transmit an integrated sample to the master unit during a portion of the frame, the method comprising the steps of:
- transmitting at least once by the master unit during a master unit portion of the frame a data update request message comprising an identification of an initial sample sequence number from which integration by the at least one sensor unit has to be carried out;
integrating by the at least one sensor unit the sample values from the initial sample sequence number to a current sample sequence number;
transmitting during a further portion of the frame by the at least one sensor unit the integrated sample value and the identification for the current sample sequence number;
receiving by the master unit the integrated sample value and the identification of the current sample sequence number; and
storing in the master unit at least the identification of the current sample sequence number.

Abstract
A method of enabling a wireless communication between a master unit and at least one sensor unit is executed within a frame, the sensor unit having an internal data sampling frequency and being adapted to store samples with corresponding sample sequence numbers. The sensor unit transmits an integrated value to the master unit. The master unit transmits, during a master unit portion of the frame, a data update request message comprising an initial sample sequence number from which integration by the at least one sensor unit has to be carried out. The sensor unit integrates the sample values from the initial sample sequence number to a current sample sequence number and then transmits the integrated sample value and the current sample sequence number. The master unit receives the integrated sample value and current sample sequence number and stores at least the current sample sequence number.

15. A system comprising a master unit and at least one sensor unit, wherein the master unit and the at least one sensor unit are arranged to communicate using a wireless communication, said at least one sensor unit having one or more channels and a buffer memory and being further arranged for sampling the one or more of its channels with a data sampling frequency and for storing resulting sample in the buffer memory together with a corresponding sample sequence number, wherein the at least one sensor unit is further arranged to transmit an integrated sample to the master unit during a portion of the frame, wherein:
-
the master unit is adapted to transmit during a master unit portion of the frame a data update request message comprising an identification of an initial sample sequence number from which integration by the at least one sensor unit has to be carried out; the at least one sensor unit is adapted to integrate the sample values from the initial sample sequence number to a current sample sequence number and to transmit during a further portion of the frame the integrated sample value and the identification for the current sample sequence number; and the master unit is further adapted to receive the integrated sample value and the identification of the current sample sequence number and to store at least the identification of the current sample sequence number.
