Control method and control system of carbon dioxide incubator and carbon dioxide incubator

Abstract

A control method of a carbon dioxide incubator includes the following steps: obtaining a current temperature and preset temperature of an inner chamber of the carbon dioxide incubator; outputting indirect heating power of an inner chamber wall according to a preset PID control algorithm; judging whether the temperature difference between the preset temperature and the current temperature belongs to a steady-state interval; if the temperature difference between the preset temperature and the current temperature belongs to the steady-state interval, obtaining minimum power of indirect heating ofthe inner chamber wall in a first preset period under the condition that the temperature difference belongs to the steady-state interval; generating set power according to the minimum power; and adjusting the set power to initial power of indirect heating of the inner chamber wall in a second preset period continuous with the first preset period, wherein the set power is greater than or equal tothe minimum power. The invention also discloses a control system and the carbon dioxide incubator. After the carbon dioxide incubator enters steady-state operation, pre-intervention is directly performed on the initial power of the next cycle according to the current operation state, so that the initiative of temperature control is realized, and the control effect is improved.

Description

Technical field [0001] The invention belongs to the technical field of cultivation devices, and particularly relates to a control method of a carbon dioxide incubator, a control system, and a carbon dioxide incubator adopting the control method. Background technique [0002] The carbon dioxide incubator is an advanced instrument for cell, tissue, and bacterial culture. It is a necessary equipment for immunology, oncology, genetics and bioengineering. It is widely used in the research and production fields of microorganisms, agricultural sciences, and pharmacology. The carbon dioxide incubator can cultivate cells, tissues and bacteria in vitro by simulating the growth environment of cells, tissues, and bacteria in the organism. Generally, the incubator requires a stable temperature, a stable carbon dioxide level, a constant pH and a high relative saturation humidity. [0003] A common carbon dioxide incubator is composed of three main parts: a shell, a working chamber, and a contr...

AI Technical Summary

Problems solved by technology

[0005] The present invention is aimed at the carbon dioxide incubator in the prior art. When the temperature of the inner chamber reaches the set value and the heat stored in the insulation cotton of the box is dissipated, the actual power of the indirect heating of the inner chamber wall is low, causing the actual temperature to deviate from the set temperature. , leading to the problem of fluctuations in the temperature of the inner chamber, providing a new control method for carbon dioxide incubators
