Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing jockey pump controllers in fire protection systems lack effective data logging and diagnostic capabilities, making it difficult to identify causes of intermittent cycling and potential failures, which can lead to unnecessary operation of the fire pump, increased wear, and potential system failures.
Innovation Solution
A programmable microcontroller-based jockey pump controller with an input/output expansion module and memory for storing event statistics, enabling remote alarm monitoring and data logging to track operational events, pressure values, and historical data for enhanced diagnostics and troubleshooting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a programmable microcontroller with data logging capabilities is implemented in the jockey pump controller, then diagnostic capabilities and system reliability are improved, but device complexity increases
Solution Approach 1:
The controller performs preliminary data logging of pressure values, operational events, and system parameters during normal operation. This preliminary action captures diagnostic information before failures occur, enabling proactive maintenance and reducing system reliability issues without requiring complex real-time monitoring hardware.
Solution Approach 2:
The microcontroller serves as an intermediary between the jockey pump system and the fire pump controller, transmitting diagnostic data and operational statistics. This intermediary function enables enhanced diagnostics without directly complicating the core pump control mechanism, as the microcontroller processes and communicates information through standardized interfaces.
2Loss of time
If real-time data communication and remote monitoring are implemented, then downtime is reduced and productivity is improved, but loss of information and communication requirements increase
Solution Approach 1:
The controller implements feedback mechanisms that continuously monitor pressure values, operational status, and system parameters, transmitting this information to remote monitoring systems. This feedback loop enables real-time detection of abnormal conditions, allowing maintenance personnel to respond promptly and reducing system downtime without requiring complex communication infrastructure.
Solution Approach 2:
The system performs preliminary data collection and logging of operational events before actual failures occur. By capturing and transmitting diagnostic information in advance, the system reduces response time and downtime while managing communication requirements through efficient data packaging and transmission protocols.
3Ease of repair
If event statistics and historical data are stored in memory, then ease of repair and diagnostics are improved, but manufacturing complexity increases
Solution Approach 1:
The controller performs self-service diagnostics by automatically logging operational events, pressure values, and system parameters in internal memory. This self-service capability stores diagnostic information that facilitates easier repair and troubleshooting without requiring external monitoring equipment, while the memory implementation uses standard, readily available components that do not significantly increase manufacturing complexity.
