Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pump station monitoring systems are reactive and lack proactive methods to accurately assess performance, capacity utilization, and determine maintenance needs under varying environmental conditions, leading to inefficient servicing and potential flooding risks.
Innovation Solution
A method for monitoring pump stations that determines Inflow data, Pump Station Max Capacity data, and momentary and typical Pump Station Capacity Utilization (PSCU) using formulas based on rest-time and run-time, allowing for proactive assessment and prioritization of maintenance and investments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If pumps are serviced at regular time intervals, then maintenance is performed, but pumps operating within acceptable parameters are serviced when not needed and faulty pumps are not maintained when needed
Solution Approach 1:
The system performs preliminary assessment of pump station capacity utilization by continuously monitoring inflow data and comparing it against historical patterns and theoretical capacity. This early detection allows maintenance to be scheduled proactively based on actual performance trends rather than fixed schedules, enabling maintenance before failures occur while avoiding unnecessary servicing of healthy pumps.
Solution Approach 2:
The system establishes feedback loops that continuously monitor pump station performance parameters (inflow, capacity utilization, operational patterns) and compare them against theoretical capacity and historical data. This feedback mechanism provides real-time intelligence on pump station health, allowing dynamic adjustment of maintenance schedules based on actual condition rather than predetermined time intervals.
2Loss of information
If pump stations are monitored using traditional methods, then operating parameters are tracked, but there is no optimal automatic way to decide what part of the system needs upgrade or service
Solution Approach 1:
The system enables self-service monitoring by automatically collecting inflow data from sensors, calculating capacity utilization ratios, comparing performance against theoretical capacity, and generating maintenance recommendations. The pump station essentially monitors itself and its own performance trends without requiring complex external analysis systems, reducing information loss while maintaining manageable system complexity.
Solution Approach 2:
The system transforms raw operational data (inflow measurements, operational timing) into meaningful performance parameters (capacity utilization ratio, efficiency metrics, trend indicators). By converting raw data into standardized performance parameters that can be directly compared against theoretical capacity and historical patterns, the system simplifies decision-making about maintenance and upgrades without requiring complex analytical systems.
3Reliability
If reactive alarm systems are used to detect flooding, then alarms are triggered when flooding occurs or is imminent, but there is no proactive ability to predict or prevent flooding
Solution Approach 1:
The system performs preliminary analysis by continuously calculating capacity utilization ratios and comparing them against historical patterns and theoretical capacity limits. This early detection of capacity constraints allows the system to predict potential flooding conditions before they occur, providing advance warning and enabling proactive measures to prevent flooding rather than reacting after it begins.
Solution Approach 2:
The system establishes feedback mechanisms that continuously monitor capacity utilization trends and compare them against safety thresholds and historical performance. This feedback loop detects deteriorating conditions early and provides advance warning of potential flooding, enabling proactive intervention before actual flooding occurs, thereby extending the lead time for prevention measures.

AI summary
The invention relates to a method for monitoring the operation of a pump station (1), wherein the pump station (1) comprises a tank (6) for temporary storage of a liquid, an inlet (7) for influent liquid, an outlet (8), and at least one pump (2) configured for transporting the liquid away from the tank (6) via said outlet (8). The method is characterized by the steps of, monitoring the inflow of liquid to the tank (6) during at least a part of a predetermined time period (T) and determining Inflow data (IN) that is representative for the inflow of liquid during the predetermined time period (T), determining Pump Station Max Capacity data (PSMC) that is representative for the max capacity of the pump station (1) during the predetermined time period (T), for the predetermined time period, determining a momentary Pump Station Capacity Utilization (PSCUM) based on the determined values of Inflow data (IN) and Pump Station Max Capacity data (PSMC), using the overall formula PSCUM (%) = 100 * IN / PSMC, and determining a typical Pump Station Capacity Utilization (PSCUT) for the pump station (1) based on at least one momentary Pump Station Capacity Utilization (PSCUM) value.
