AI Technical Summary

Technical Problem

The increasing number of sensors in tire management systems leads to higher energy consumption and radio transmission issues, particularly due to the need for frequent data frames, which is problematic for battery-powered devices integrated within tires.

Method used

A method and device that utilize the Bluetooth Low Energy (BLE) protocol for unidirectional transmission of measurement sequences, encoding data as deviations from a reference value, and incorporating redundancy to minimize energy consumption and ensure data integrity.

Benefits of technology

This approach reduces energy consumption and maintains data integrity by optimizing frame transmission, allowing for efficient communication of tire condition data without frequent connections, thereby extending battery life and ensuring reliable data retrieval.

Abstract

The invention relates to a method for communicating values measured by at least one sensor (21, 22, 23) of a device (20) associated with a tire (11) to a remote receiving member (30), the method comprising steps of: - acquiring (S1) measurements via the at least one sensor; - sampling (S2) and storing (S3) the measurements to form an ordered series; - determining (S4) a sequence of values from the ordered series; - transmitting (S5) a frame (40) to the remote receiving member (30), the frame comprising a unique identifier (441) of the device, an increment indicator (442), a format indicator (444) indicating the format of the sequence of values, and this sequence of values (443), this sequence of values (443) comprising at least one reference value and a set of representations of other values in the form of a deviation relative to the reference value.
