Worksite Vehicle Collision Prevention Under Communication Loss
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for preventing collisions between vehicles at a work site rely heavily on wireless communication with a remote server, which can be unreliable, leading to potential safety risks when communication disruptions occur.
Innovation Solution
A computer system with a control unit that receives location information from vehicles and identifies communication disruptions, transmitting instructions to other vehicles to maintain a safe distance based on the last known location of the vehicle experiencing a disruption, ensuring collision prevention even when communication with the server is lost.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a remote server is used to manage vehicle operations and zones, then collision prevention capability is improved, but system reliability deteriorates due to dependency on continuous wireless communication
Solution Approach 1:
The control unit pre-calculates and stores safety positions and exclusion zones based on the last known location of vehicles before communication is lost. This preliminary preparation ensures that collision prevention instructions can be immediately transmitted to other vehicles without requiring real-time communication with the first vehicle, thus maintaining reliability while reducing dependency on continuous communication infrastructure.
Solution Approach 2:
The control unit acts as an intermediary that stores and processes location information and safety parameters locally. When communication with the first vehicle is lost, the control unit uses its stored data to generate and transmit collision prevention instructions to other vehicles, serving as a mediator that maintains system functionality without requiring direct communication between all vehicles and the server.
2Reliability
If continuous communication monitoring is implemented, then safety response time is improved, but energy consumption increases
Solution Approach 1:
The control unit monitors communication status at periodic intervals rather than continuously. When a communication disruption is detected, the system activates safety protocols using pre-calculated data. This periodic monitoring approach maintains adequate safety response capability while significantly reducing energy consumption compared to continuous communication monitoring.
Solution Approach 2:
Safety positions, exclusion zones, and collision prevention instructions are pre-calculated and stored before communication is lost. This preliminary computation eliminates the need for continuous real-time calculations and communications, reducing energy consumption while ensuring rapid safety response when disruptions occur.
