Remote Firefighting Pump Control With PLC-Based Flow and Pressure Logic
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fire-fighting control systems rely on manual operation by a single engineer, leading to increased costs and potential human errors due to the need for verbal communication and interpretation of commands from multiple firefighters, and lack the ability to simulate operations for training purposes.
Innovation Solution
A control system with a programmable logic controller that automatically adjusts valve states and pump operations based on user-input parameters, allowing remote control of a fire-fighting device and enabling simulation training through a user interface and wireless communication with remote components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual control operation is used with verbal communication from multiple firefighters, then the system can respond to firefighter needs, but the cost of operations increases and human error potential increases
Solution Approach 1:
The control system automatically monitors parameters and executes control actions without requiring manual intervention. The system serves itself by autonomously interpreting firefighter needs from verbal commands, determining appropriate control actions, and executing them through automated valve and pump control, eliminating the need for manual operation while maintaining response effectiveness
Solution Approach 2:
The patent replaces the manual mechanical control system with an automated electronic control system. Instead of engineers manually manipulating valves and monitoring gauges, the system uses microprocessors, sensors, and automated control algorithms to monitor system state, interpret verbal commands, and execute control actions electronically, thereby improving reliability and operational efficiency
2Adaptability or versatility
If a single engineer manually operates controls for multiple firefighters and equipment, then the system can manage all operations, but the complexity of manual coordination increases
Solution Approach 1:
The automated control system serves multiple functions simultaneously: it monitors multiple firefighters' verbal commands, controls multiple valves and pumps, manages water tank levels, and coordinates all operations through a single integrated system. This universal system replaces the need for a single engineer to manually coordinate all these separate functions, reducing coordination complexity while maintaining multi-functionality
Solution Approach 2:
The control system divides the complex coordination task into separate functional modules: verbal command interpretation, system state monitoring, control decision logic, and execution of specific control actions. Each module handles a specific aspect of the control task independently, reducing the overall complexity of coordinating multiple firefighters and equipment while maintaining the ability to perform all necessary functions
3Ease of operation
If verbal communication is used to convey flow rate and pressure changes, then the system can respond to firefighter needs, but the difficulty of understanding commands increases due to environmental factors
Solution Approach 1:
The system continuously monitors actual system parameters (water flow rate, pressure, tank levels) and provides feedback to verify that executed commands achieve the desired effect. This feedback mechanism ensures that even if verbal commands are partially misunderstood or transmitted poorly, the system can detect and correct deviations from intended operations, maintaining ease of operation while compensating for information loss in communication
Data Source
AI summary
A control system for use with a fire-fighting device includes a remote component having a touch sensitive screen configured to receive a user-requested parameter of fluid and to display a plurality of indicators associated with the fire-fighting device. The control system also includes a base component including a programmable logic controller having predefined logic stored thereon. The base component automatically controls operation of the pump based on the predefined logic and the user-requested parameter of fluid. The remote component receives signals from the base component and presents, via the touch sensitive screen, at least one of a first of the plurality of indicators indicative of a water volume associated with a first water source stored at a fire fighting device, and a second of the plurality of indicators indicative of a water pressure associated with a second water source remote from the fire-fighting device.
