Abstract

The invention discloses a pipetting control method and device. The method comprises the steps: after it is determined that pipetting equipment executes pipetting operation, triggering image collection equipment to execute image collection operation on a target container, obtaining a first image of the target container, wherein the target container is a liquid transferring object of the pipetting equipment; performing image recognition on the first image to obtain a first image recognition result; determining a height value of the target solution in the target container based on the first image recognition result; and based on a height difference value between the height value and a target height value, controlling the pipetting equipment to continuously execute pipetting operation on the target container until the liquid level height of the target solution in the target container is the same as the target height value. The technical problem that the solution is easily polluted due to the fact that contact operation is adopted for constant volume treatment of the solution in the prior art is solved.

Description

technical field [0001] The present invention relates to the technical field of automated production, in particular to a pipetting control method and device. Background technique [0002] At present, the liquid constant volume technology is based on the liquid density to calculate the volume. Such solutions lead to poor volume constant accuracy and require additional measurement of the solution density. The density constant volume meeting is used in a large number of various solution volume constant operations in automated production scenarios. Time-consuming, poor precision, and the use of measuring instruments to contact liquids will also indirectly lead to contamination of the sample solution. [0003] For the above problems, no effective solution has been proposed yet. Contents of the invention [0004] The embodiment of the present invention provides a liquid pipetting control method and device, to at least solve the technical problem that in the related art, the cons...
