Embodiment

[0026] Such as figure 1 As shown, the present invention discloses a method for picking cryopreservation tubes based on visual aid verification, which is suitable for picking cryopreservation tubes in a deep low temperature environment. It can monitor the pipe picking process and quickly and timely find wrong pipe picking information. It mainly relies on the camera to take pictures and intelligently analyze the pictures, and then interacts with the PLC controller for data interaction and realizes error logic. Relying on the visual processing library that comes with the smart camera, the collected Each picture obtained is analyzed according to the configured rules, and the information on the presence or absence of the cryotube hole in the picture can be accurately obtained. Through the data interaction with the PLC register, the purpose of comparison is realized, and the process of picking the tube is verified.

[0027] In specific operations, it is preferred to write data into ...

Abstract

The invention discloses a cryopreservation tube selection method based on visual auxiliary verification, and mainly solves the problems that existing cryopreservation tube selection is likely to go wrong, and error information cannot be quickly monitored in time under the condition of tube selection errors. According to the method, two intelligent cameras are arranged, the two cameras may be a source position camera and a target position camera according to different tube selection requirements, the two cameras are different in starting time period and are used for recording vacancy changes ofa cryopreservation box before and after selection of a source cryopreservation tube respectively, and by means of a visual processing library of the intelligent cameras, each collected picture is analyzed according to a configured rule, whether cryopreservation tube hole sites exist in the pictures or not can be accurately obtained, the purpose of comparison is achieved through data interaction with a PLC register, the accuracy of each tube selection is doubly verified, and the accuracy of tube selection is improved. Therefore, the cryopreservation tube selection method is suitable for popularization and application.

Description

technical field [0001] The invention relates to the technical field of cryopreservation tube selection, in particular to a method for selecting cryopreservation tubes based on visual aided verification. Background technique [0002] Cryopreservation tube is a kind of strain preservation tube, mainly composed of three parts: preservation solution, preservation tube and small porcelain beads. It is a container for preservation of strains in the laboratory, used for preservation or transfer of strains. There are 25 small ceramic beads in the preservation tube for the adsorption and preservation of bacteria. [0003] In the cryopreservation tube picking operation in a deep low temperature environment, due to the interference of various factors such as low temperature, static electricity, and air humidity, it is impossible to guarantee 100% accuracy of every mechanical tube picking action. Therefore, how to pick tubes In the event of an error, it becomes particularly important t...
