Transmitting Unit Movement Detection Power Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing transmitting units continuously transmit signals, leading to high power consumption and short battery life, especially in scenarios like military exercises where many units are used simultaneously, and they often require continuous decoding by receivers, which is inefficient and costly.
Innovation Solution
A transmitting unit with a detection mechanism that activates only when movement is detected within a restricted predefined volume, reducing power consumption by transmitting coded position information only when necessary, using infrared detection and pyro-electric members, and employing a processing device to control the transmitter based on movement direction and volume definitions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the transmitter continuously transmits signals of coded position information, then the position information is always available to the receiver, but the power consumption is high and battery life is short
Solution Approach 1:
The transmitter operates in periodic cycles, alternating between active transmission states and inactive standby states. A detection mechanism monitors the environment and triggers transmission only when movement is detected, rather than maintaining continuous transmission. This periodic operation significantly reduces power consumption while ensuring position information is transmitted at relevant moments when objects move within the monitored space.
2Use of energy by moving object
If the transmitter is activated only when movement is detected, then the power consumption is reduced, but the position information may not be transmitted continuously
Solution Approach 1:
A detection mechanism provides feedback about movement within the monitored space to the transmitter control system. When movement is detected, the system receives feedback signals that trigger the transmitter to activate and send position information. This feedback loop ensures transmission occurs at appropriate moments when position changes are detected, maintaining reliability for tracking moving objects while avoiding unnecessary continuous transmission.
3Reliability
If multiple transmitting units are used simultaneously in military exercises, then the position tracking capability is improved, but the overall power consumption and cost increase
Solution Approach 1:
Each transmitting unit in the military exercise system operates periodically rather than continuously, activating only when movement is detected in its monitored area. This approach allows multiple units to be deployed for comprehensive position tracking coverage while each unit consumes power only when necessary, significantly reducing the overall power consumption and operational costs across the entire system of multiple transmitting units.

AI summary
A transmitting unit includes a transmitter for transmitting signals of coded information about a position close to the unit in a space substantially unreachable by a satellite-based navigating system so as to provide a receiver arranged on a moving object present in the space with the position information for determining the position of the object. The transmitter is adapted to normally be in an inactive non-transmitting state, and the unit further includes a detector adapted to detect movement of an object within a space and activate the transmitter to transmit signals only when movement of an object in the space is detected.
