Sample Rack Scheduling Control for Chemiluminescence Detectors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The utilization rate of rail-type sample delivery apparatuses in chemiluminescence detectors is low due to delayed sample addition, leading to reduced overall throughput in biomedical devices.
Innovation Solution
A sample rack scheduling control method and system that manages delivery paths by marking position nodes as available or occupied, allowing sample racks to move only when the path is unblocked, enabling parallel delivery and improving efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If a rail type sample delivery apparatus is adopted to automatically deliver samples to different instruments, then the device achieves complete automation, but the utilization rate of the rail type delivery is relatively low and the sample adding is delayed
Solution Approach 1:
The patent divides the continuous rail delivery path into discrete position nodes (start position node, target position node, and intermediate nodes). Each node can be independently marked as available or occupied, allowing multiple sample racks to be delivered simultaneously along different segments of the rail, thereby increasing utilization rate while maintaining automation.
2Extent of automation
If a rail type sample delivery apparatus is adopted to automatically deliver samples to different instruments, then the device achieves complete automation, but the overall throughput of the instruments is reduced
Solution Approach 1:
The patent implements preliminary action by checking the availability of target position nodes and intermediate nodes before initiating sample rack delivery. The system marks nodes as occupied in advance when they become available, and prevents new deliveries from starting until nodes are freed. This coordination mechanism ensures that multiple sample racks can be delivered in parallel without blocking instruments, thereby increasing overall throughput while maintaining automation.
3Ease of operation
If sample racks are delivered sequentially one after another, then the delivery process is simple to control, but the delivery efficiency is low and the utilization rate of sample delivery rail is reduced
Solution Approach 1:
The patent implements a feedback mechanism where the control system continuously monitors the state of each position node on the rail (available or occupied). When a target position node and its intermediate nodes become available, the system automatically initiates delivery of the next sample rack. This feedback-driven approach enables parallel delivery of multiple sample racks while maintaining simple centralized control, thereby increasing delivery efficiency without complicating the control architecture.

AI summary
Some embodiments of the disclosure provide a sample rack scheduling control method. The method includes the following steps: respectively obtaining a state of each position node on each preset delivery path, wherein the state of each position node includes an available state and an occupancy state; and for each of the delivery paths, if a target position node on the delivery path and position nodes between the target position node and a start position node all are in the available state, marking the target position node on the delivery path and the position nodes between the start position node and the target position node all as the occupancy state, and controlling a current sample rack at the start position node to move to the target position node. The present disclosure further provides a sample rack scheduling control system and a medical detection device.
