AI Technical Summary

Problems solved by technology

Where two or more liquid additions are required, a single probe is used to aspirate the liquid and there is a high risk of cross-contamination of liquids from the individual probes
Moreover, it takes a long time to draw the two liquids, which slows down the speed of the analysis experiment

Abstract

The invention provides a signal processing method and device and a liquid level detection system, and relates to the field of bio-medical treatment. The signal processing method comprises the steps of obtaining first signal data of each probe of two or multiple probes which are used in cooperation; adjusting the first signal data to obtain second signal data of two or multiple probes which are used in cooperation, so that the absolute value of the difference value between the second signal data of two or multiple probes which are used in cooperation is larger than a preset signal threshold value. According to the signal processing method and device and the liquid level detection system, the accuracy of the detection result of the probes can be improved.

Description

technical field [0001] The invention relates to the field of biomedicine, in particular to a signal processing method, device and liquid level detection system. Background technique [0002] In the biomedical field, liquids are frequently analyzed. Driven by the motor, the probe used for absorbing the liquid in the liquid analysis device moves downward or upward in the liquid holding container. In order to prevent the probe from hitting the bottom of the liquid holding container and from absorbing unnecessary liquid, the probe sucks the liquid when it touches the liquid level of the liquid in the liquid holding container. [0003] In some analytical experiments, two or more additions of reagents are required. When working with a single probe, it is necessary to align the single probe with the first liquid, control the descent of the single probe, and reset the single probe after sucking the first liquid. Then align the single probe with the second liquid, control the drop...
