Worksite Controller Event-Triggered Data Retrieval
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing worksite data management systems, such as the one described in U.S. Patent Publication 2007/0125979, are inadequate in coordinating fleet data during events and lack the ability to retrieve additional information effectively, leading to potentially ineffective and costly responses to machine and worksite conditions.
Innovation Solution
A data management system comprising sensory devices, locating devices, and communication devices onboard machines, along with a worksite controller that captures and correlates data to trigger events and selectively retrieve information from multiple machines, enabling coordinated response to worksite conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If data from only one machine is used to trigger events, then the system complexity is reduced, but the data sufficiency and effectiveness of event responses deteriorate
Solution Approach 1:
The system merges data from multiple machines by receiving data packets from plurality of machines at the worksite, each packet including sensor data and location information. When an event is triggered by one machine, the system retrieves relevant data from other machines to provide comprehensive context for effective response generation.
Solution Approach 2:
The worksite controller acts as an intermediary that coordinates data retrieval across multiple machines. It receives trigger events from any machine, determines which additional machines have relevant data based on location and event type, and aggregates this information before generating responses.
2Loss of information
If data from multiple machines is coordinated during events, then the data sufficiency and response effectiveness are improved, but the system complexity increases
Solution Approach 1:
The system segments data management into modular components: each machine independently generates data packets with sensor readings and location information, the worksite controller manages event triggering and data retrieval coordination, and the response generation module processes aggregated data. This segmentation reduces overall system complexity while enabling multi-machine data coordination.
Solution Approach 2:
The system performs preliminary actions by continuously receiving and storing data packets from all machines before events occur. Each data packet includes timestamp and location information, preparing the data in advance so that when an event is triggered, relevant information can be quickly retrieved and aggregated without complex real-time coordination.
3Reliability
If additional data is retrieved from other machines when events are triggered, then the quality of event responses is improved, but the response time and system resource usage increase
Solution Approach 1:
The system applies partial action by selectively retrieving data only from machines whose locations and sensor types are relevant to the triggered event, rather than retrieving data from all machines. The worksite controller determines which machines have pertinent information based on the event type and location, reducing unnecessary data retrieval while ensuring sufficient information is obtained for effective responses.
