AI Technical Summary

Technical Problem

In fully automated production lines, it is difficult to determine the transmission status of sample racks when they are being assembled with instruments from other manufacturers, leading to abnormal sample transport and TAT timeouts.

Method used

By introducing a timer into the sample transfer system, the time it takes for the sample rack to be fed from the buffer structure to the analyzer is timed and compared with a preset duration. When the timeout occurs, an abnormal prompt is issued. The system monitors the operating status of the analyzer and the sample outlet channel, clears the binding relationship, and sets up a buffer area to handle abnormal sample racks.

Benefits of technology

It enables real-time monitoring of the sample rack's transmission status within the analytical instrument, allowing for timely handling of abnormal situations, preventing a decrease in transportation efficiency, and ensuring the normal flow of samples.

Abstract

The application provides a control method of a sample transfer system, the sample transfer system comprising a buffer structure, a timer and a controller, the timer being in signal connection with the controller, the buffer structure being used for temporarily storing a sample rack, the sample rack being capable of being transferred from the buffer structure to an analysis instrument and being capable of being transferred from the analysis instrument to the buffer structure after the analysis instrument completes sample suction, and the control method comprising: starting timing by the timer from a sample-in time and obtaining a timing duration, wherein the sample-in time is a time when the sample rack is transferred from the buffer structure to the analysis instrument; comparing the timing duration with a preset duration t, and when the timing duration is greater than or equal to the preset duration t, the controller sends a first conveying abnormality prompt, wherein the preset duration t is an estimated maximum duration from sample-in to sample-out of the sample rack. The technical scheme of the application can effectively solve the problem in the related art that when a pipeline is spliced with an instrument of another manufacturer, it is difficult to judge the transmission state of the sample rack.
