Solution Overview

Problem

In anti-intrusion alarm systems, home automation, and temperature management, devices such as sensors and transmitters face frequent battery replacements due to significant electrical energy consumption by radio modules for communication, leading to reduced battery longevity and potential noise-induced unwanted activations.

Innovation Solution

A method and device for managing the activation of a radio module's reception chain by alternating between reception and standby modes based on predetermined byte reception, optimizing energy consumption while maintaining robustness against noise and ensuring preamble detection.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the radio module reception chain is continuously activated to ensure robust preamble detection, then the detection reliability is improved, but the electrical energy consumption increases significantly

Engineering Contradiction:

Improvepreamble detection reliabilityVSAvoidelectrical energy consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The reception chain is activated periodically in short bursts (first duration, second duration) rather than continuously. The system alternates between active reception periods and standby periods (third duration), creating a periodic activation pattern that reduces overall energy consumption while maintaining detection capability.

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

The system performs preliminary detection actions by activating the reception chain for short durations to check for preamble presence before committing to full reception mode. This allows the system to prepare for potential message reception without continuously consuming full power.

Inventive Principle:

Principle #10Preliminary action

2Speed

If the reception chain is activated frequently to detect preambles, then the detection speed is improved, but false activations due to noise increase

Engineering Contradiction:

Improvepreamble detection speedVSAvoidnoise-induced false activations

Core Design Contradiction:

SpeedVSObject-affected harmful factors

Solution Approach 1:

The system applies partial action by using multiple short activation durations (first duration, second duration) rather than a single long activation. This allows the system to detect preambles that may start at different times while using less total activation time, reducing false activations from noise.

Inventive Principle:

Principle #16Partial or excessive action

Solution Approach 2:

The system uses feedback by monitoring whether predetermined bytes with predetermined values are received during each activation period. Based on this feedback, the system decides whether to maintain reception mode or transition to standby, adjusting its behavior according to actual signal conditions.

Inventive Principle:

Principle #23Feedback

3Reliability

If the reception chain remains in reception mode for extended periods to capture complete messages, then the message reception completeness is improved, but the battery longevity decreases

Engineering Contradiction:

Improvemessage reception completenessVSAvoidbattery longevity

Core Design Contradiction:

ReliabilityVSDuration of action of stationary object

Solution Approach 1:

The reception chain operates in periodic cycles with multiple short reception periods (first duration, second duration) separated by standby periods (third duration). This periodic operation maintains message detection capability while dramatically reducing the total time the reception chain consumes electrical energy, thereby extending battery life.

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

The message reception process is segmented into multiple discrete detection phases (first duration, second duration) rather than requiring a single continuous reception period. This segmentation allows the system to detect preambles and initiate reception only when necessary, reducing overall energy consumption.

Inventive Principle:

Principle #1Segmentation

AI summary

The invention relates to a method for managing the activation of a receiving chain of a radio module receiving at least one message consisting of a preamble and at least one frame, the method comprising the steps of: - putting (E302) the receiving chain of the radio module into a receiving mode for a first duration, - determining (E303) whether a predetermined number of bytes having a predetermined value is received during the first duration, - maintaining (E303) the receiving chain of the radio module in the receiving mode for a second duration, if the predetermined number of bytes having a predetermined value is received during the first duration, - determining (E305) whether a predetermined number of bytes having a predetermined value is received during the second duration, - putting (E300) the receiving chain of the radio module into a standby mode for a third duration if the predetermined number of bytes is not received during the first duration.
