Electronic Badge Tracking with Dynamic Proximity Zones
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing proximity detection systems for industrial vehicles struggle with false alarms and inability to contextualize pedestrian presence, lacking effective machine-to-machine communication and environmental awareness.
Innovation Solution
A control system for industrial vehicles that integrates a badge communicator and an information linking device, utilizing short-range communication with electronic badges and environmental-based location tracking to dynamically detect and track badges, reducing false alarms through zone ranging based on vehicle speed, direction, and environmental awareness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixed short range communication zone is used for badge detection, then all badges within range are detected, but false alarms occur and contextual information about pedestrian presence is lost
Solution Approach 1:
The fixed short range communication zone is segmented into multiple dynamic zones based on vehicle operating parameters. The information linking device creates zone subdivisions that reflect actual vehicle context (speed, direction, acceleration), allowing the system to distinguish between relevant and irrelevant badge detections. This segmentation enables contextual awareness by treating different spatial regions differently based on vehicle state.
Solution Approach 2:
The system transitions from a static fixed range zone to dynamic zones that adjust in real-time based on vehicle operating parameters. The badge communicator and information linking device continuously update zone definitions according to vehicle speed, direction, and acceleration, making the detection zones adaptive to current vehicle context rather than fixed in space.
2Adaptability or versatility
If environmental-based location tracking is integrated with badge communication, then machine-to-machine communication is improved, but device complexity increases
Solution Approach 1:
The system merges the badge communicator's short-range wireless communication capability with the environmental-based location tracking system's positional data. The information linking device integrates these two previously separate functions, combining badge detection with vehicle location, speed, and direction information to create a unified contextual awareness system.
Solution Approach 2:
The information linking device serves multiple functions: it processes badge communications, tracks vehicle environmental parameters, generates dynamic zones, and makes control decisions. This multi-functional approach consolidates several system components into a single versatile device that handles both communication and location-based control tasks.
3Reliability
If dynamic zone ranging based on vehicle parameters is implemented, then false alarms are reduced, but measurement and detection complexity increases
Solution Approach 1:
The information linking device continuously monitors vehicle operating parameters (speed, direction, acceleration) and uses this feedback to dynamically adjust zone definitions. The system creates a closed-loop control where detection results feed back into zone parameter adjustments, allowing the zones to adapt automatically to changing vehicle conditions without manual intervention.

AI summary
A control system for an industrial vehicle includes a badge communicator and an information linking device. The badge communicator has a transceiver for short range communication with electronic badges that are within a fixed short range of the badge communicator, defining a first zone. The information linking device is programmed to execute program code. The program code extracts a current state of an operating parameter read from an industrial vehicle network bus, generates a second zone within the first zone that is defined based upon the extracted industrial vehicle operating parameter, detects a presence of an electronic badge within the first zone, determines whether the electronic badge is within the second zone, performs a first action if the detected electronic badge is not within the second zone, and performs a second action if the electronic badge is within the second zone.
