Vehicle Zone Communication System for Instruction Logging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle control systems lack the ability to record and verify verbal instructions given to vehicles entering or operating within restricted zones, such as construction zones, leading to difficulties in ensuring compliance with protocols and permissions.
Innovation Solution
A communication system that includes a first device at the zone to accept audio data from field operators, convert it to text, and provide this data to vehicle operators for display, while also storing it for record-keeping, using a processor and database to ensure accurate transmission and storage of vehicle control commands.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If voice-over-radio communication is used to communicate instructions from field operator to vehicle operator, then communication can be maintained without electronic systems, but the ability to record and verify instructions is lost
Solution Approach 1:
A dispatch center acts as an intermediary between the field operator and vehicle operator. The field operator communicates instructions to the dispatch center, which then transmits them to the vehicle operator. This intermediary system enables recording and verification of instructions while maintaining communication reliability.
Solution Approach 2:
The system implements feedback by having the vehicle operator acknowledge received instructions and by maintaining logs of all communications at the dispatch center. This feedback mechanism ensures that instructions are properly transmitted, recorded, and verified, resolving the information loss problem.
2Loss of information
If electronic communication system is used between field operator and vehicle, then instructions can be recorded and verified, but the system complexity increases
Solution Approach 1:
The dispatch center serves multiple functions: it records instructions, verifies communication, logs interactions, and facilitates two-way communication between field operators and vehicle operators. This multi-functionality reduces the need for separate specialized systems, thereby managing complexity while achieving information retention.
3Productivity
If field operator directly communicates with vehicle operator without dispatch center, then communication speed is faster, but verification and logging capability is reduced
Solution Approach 1:
The dispatch center prepares and logs instructions before they are transmitted to the vehicle operator. All communications are pre-recorded and verified in advance, ensuring that verification and logging capabilities are maintained without significantly impacting communication speed during critical operations.
Data Source
AI summary
A system is provided that includes a first communication device located at or associated with a determined zone and can accept field data; a second communication device located on or associated with at least one vehicle approaching or traversing the determined zone; and at least one controller or a control system. The controller or control system can receive the field data from the first communication device; convert at least a portion of the field data to a message comprising vehicle data; and provide the vehicle data to a vehicle controller or a vehicle operator, and thereby can control or operate the at least one vehicle based using the provided vehicle data.
