Multi-mode Electronic Badge for Industrial Vehicle Communication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current industrial systems face challenges in efficiently tracking and managing the activities of industrial vehicle operators and pedestrians within constrained environments, such as warehouses, due to limitations in wireless communication and data collection capabilities.
Innovation Solution
The implementation of multi-mode electronic badges that communicate via personal-area networks and local area networks, allowing for data collection and exchange between industrial vehicles and operators, and enabling mode switching between pedestrian and industrial vehicle operations, thereby enhancing situational awareness and task management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate communication systems are used for industrial vehicles and pedestrians, then communication reliability is improved, but device complexity increases
Solution Approach 1:
The electronic badge is designed to operate in multiple modes: pedestrian mode for foot traffic and industrial vehicle mode for forklift operators. The badge automatically detects and switches between modes based on motion sensors and proximity detection, allowing a single device to replace what would traditionally require separate communication systems for vehicles and pedestrians.
2Area of stationary object
If multiple separate devices are deployed for vehicle and pedestrian communication, then communication coverage is improved, but hardware requirements increase
Solution Approach 1:
The badge serves as a universal communication device that functions for both pedestrians and industrial vehicle operators. By eliminating the need for separate vehicle-mounted communication devices and using the badge for both purposes, the system reduces overall hardware requirements while maintaining comprehensive communication coverage throughout the facility.
3Measurement precision
If dedicated vehicle communication systems are used, then task management accuracy is improved, but ease of operation decreases
Solution Approach 1:
The badge dynamically adapts its interface and functionality based on the detected mode. When detected as being worn by a pedestrian, it provides pedestrian-specific information; when detected as being mounted on an industrial vehicle, it switches to vehicle-specific task management interface. This dynamic adaptation maintains ease of operation while ensuring accurate task management for each user type.

AI summary
An industrial system includes an electronic badge worn or otherwise transported by an industrial vehicle operator. The electronic badge has a housing, a processor, and a transceiver coupled to the processor that communicates on a personal-area network with a badge communicator that is provided on an industrial vehicle when the electronic badge and the badge communicator are in range of each other. Further, an activity sensor collects activity information about the industrial vehicle operator as the industrial vehicle operator performs work tasks. The electronic badge exchanges data collected by the activity sensor with the industrial vehicle, for communication to a remote server. An electronic message is communicated to the industrial vehicle for output to a display thereon, and the electronic message defines an assigned task that is based upon previously collected data from the activity sensor.
