ASRS Vehicle Fire Detection for Precise Heat Source Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automated storage and retrieval systems lack reliable information on the location of heat or fume emissions during a fire, making it difficult for firefighting crews to respond effectively.
Innovation Solution
Implementing a fire detection device on remotely operated vehicles within the system, which transmit data to a master control system to create a heat map and verify the location of heat or fume emissions, using multiple vehicles to confirm the source and generate a precise prediction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fire detection devices are installed on remotely operated vehicles, then the reliability of fire location information is improved, but the device complexity increases
Solution Approach 1:
The remotely operated vehicles are equipped with fire detection devices, making them multi-functional units that can perform both material handling operations and fire detection/verification tasks. This allows the existing vehicle fleet to serve dual purposes without adding dedicated fire detection equipment throughout the entire system.
Solution Approach 2:
The system uses the remotely operated vehicles' own sensing capabilities to detect and verify fire conditions in their immediate vicinity. The vehicles essentially monitor their own operational environment for fire hazards while performing their primary functions, eliminating the need for separate dedicated detection infrastructure.
2Measurement precision
If multiple remotely operated vehicles are used to verify heat or fume emissions, then the measurement precision of fire location is improved, but the loss of time increases
Solution Approach 1:
The master control system pre-configures multiple remotely operated vehicles to be positioned strategically throughout the automated storage and retrieval system. When a fire detection event occurs, these vehicles are already in place or can quickly relocate to verification positions, eliminating the time delay that would result from deploying vehicles from a central location.
Solution Approach 2:
The system implements a feedback mechanism where the master control system receives data from fire detection devices on multiple vehicles, processes this information to determine the most likely fire source location, and then directs specific vehicles to verify the condition. This coordinated feedback loop optimizes the verification process by sending only the necessary number of vehicles to the right locations based on initial detection data.

AI summary
An automated storage and retrieval system includes a rail system, a master control system, and a plurality of remotely operated vehicles. The rail system includes a first and second set of parallel tracks arranged orthogonally in a horizontal plane. The master control system is configured to keep track of any remotely operated vehicle operating on the rail system. The plurality of remotely operated vehicles handling storage containers, which operate on the rail system, each include first and second sets of wheels for transport on the rail system, and a fire detection device configured to transmit data from the fire detection device to the master control system. The master control system includes a processing device for processing the data from the fire detection devices so as to create a heat map of the automated storage and retrieval system.
