Proximity Transmitter Standby Control for Alarm System Energy Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing alarm systems with autonomous energy sources face high energy consumption due to continuous activation of proximity readers, even when the system is disarmed, which limits their long-term operation, especially in applications like garage doors that open frequently.
Innovation Solution
A method and system that includes a proximity transmitter/receiver capable of being activated or placed in a standby state, with a detection sensor to automatically control its activation and deactivation based on the armed or disarmed state, using a portable active wireless communication medium with a low-energy Bluetooth chip for identification and communication, allowing for efficient energy management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the proximity reader is permanently or periodically activated to ensure effective coverage area and quick response time, then the system reliability and response speed are improved, but the energy consumption increases significantly
Solution Approach 1:
The proximity reader is activated periodically rather than continuously. The system uses motion detection sensors to trigger activation only when movement is detected near the access point, and deactivates it when no movement is present. This periodic activation pattern maintains system reliability by ensuring the reader is operational when needed while dramatically reducing overall energy consumption.
Solution Approach 2:
The system dynamically adjusts the operational state of the proximity reader based on real-time conditions. When the alarm system is disarmed and no motion is detected, the reader transitions to a low-power standby mode. When motion is detected or the system is armed, the reader becomes fully active. This dynamic state management resolves the contradiction between maintaining reliability and reducing energy usage.
2Speed
If the proximity reader is activated frequently to detect transponder badges quickly, then the response time is reduced, but the energy consumption increases
Solution Approach 1:
Instead of continuous activation, the proximity reader operates in periodic bursts triggered by motion detection events. When a door approach is detected or the system transitions to armed state, the reader activates for a predetermined period to capture any transponder badges. This approach maintains quick response capability when needed while minimizing energy consumption during idle periods.
3Ease of manufacture
If the autonomous system operates independently without external power supply, then the ease of installation is improved, but the energy management complexity increases
Solution Approach 1:
The autonomous proximity reader system manages its own energy consumption through self-monitoring and automatic state transitions. Motion detection sensors automatically trigger reader activation when movement is detected, and the system autonomously transitions to standby mode when idle. This self-service capability simplifies installation by eliminating external power wiring while managing energy complexity through automated local control logic.

AI summary
The present invention relates to a method for the automatic detection, recognition, and disarming of an alarm control panel (3) for monitoring a protected area enclosed by at least one door. The system comprises the control panel (3), at least one autonomous detection and identification unit including a proximity transmitter/receiver (4b) and at least one detection sensor (5b) capable of detecting a door opening and/or passage through it, and at least one portable active wireless communication device (6) including an identification code. Following detection, the method, when the control panel is armed, commands the transmitter/receiver to activate it, then deactivates it after a predetermined time t0 to put it into standby mode, and, when disarmed, maintains it in standby mode. The invention also relates to a system suitable for its implementation.
