Truck Load Verification System for Ready Mix Plants
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems lack a verification process to ensure that the correct truck receives the intended batch at a discharge point in ready mix cement or asphalt plants, leading to potential liability due to incorrect truck loading and delivery of unique batches.
Innovation Solution
A system that includes output ID readers on trucks, a server system with databases, and a load matrix interface to verify the correct truck is loaded with the correct batch before discharge, using technologies like RF signals, QR codes, or GPS, and controlling the discharge sequence based on verification results.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If no verification process is implemented, then the loading process remains simple and fast, but the risk of incorrect truck loading increases significantly
Solution Approach 1:
The system performs verification actions before the discharge sequence is initiated. The output ID is read and verified against the batch ticket information prior to any batch constituents being discharged into the truck, preventing incorrect loading before it can occur
Solution Approach 2:
The system provides feedback by comparing the output ID read from the truck with the expected truck ID from the batch ticket. The batching control functionality receives verification results and adjusts the discharge sequence accordingly - initiating discharge only when verification succeeds or holding it when verification fails
2Reliability
If verification is performed before discharge, then incorrect deliveries are prevented, but the loading time increases due to additional verification steps
Solution Approach 1:
The verification is performed as a preliminary action before the discharge sequence begins, ensuring that the correct truck is identified and verified against the batch ticket information before any time-consuming discharge operation starts
Solution Approach 2:
The manual verification process is replaced with automated electronic verification using output ID readers that read electronic identifiers from trucks and automatically compare them with batch ticket information in the server system, significantly reducing verification time compared to manual checking
3Ease of operation
If manual verification processes are used, then the system remains simple to operate, but human errors and confusion increase
Solution Approach 1:
The system performs self-verification by automatically reading the output ID from the truck, comparing it with the batch ticket information from the server, and determining whether the correct truck is present. This automated self-service eliminates the need for manual verification operations
Solution Approach 2:
Manual verification operations are replaced with electronic automation. The output ID reader automatically captures the truck identifier, the server system retrieves the expected truck ID from the batch ticket, and the batching control functionality automatically compares these values and controls the discharge sequence based on the comparison result

AI summary
A system for verifying a load placed in one or more trucks that include a plant, a mixer, a discharge point, the one or more trucks, an output ID, an output ID reader and a material load verification non-transitory storage media. The system may also include a third-party cloud platform or an output ID reader that display data from the output ID reader that may be read, relayed and utilized for a configuration decision that would be made by a plant manager on comparing a truck file database with the load matrix interface.
