Embodiment Construction

[0032] In order to make the technical solutions and advantages of the present invention more clear, the technical solutions in the embodiments of the present invention are clearly and completely described below in conjunction with the drawings in the embodiments of the present invention:

[0033] Such as figure 1 shown as a CO 2 The temperature control method of the incubator, the method calculates the floating control parameters through the ambient temperature and the set temperature, and uses the temperature control algorithm to control the output power of the heating element, so that the CO 2 When the incubator is in the environment of 15-35°C and the set temperature is 30-50°C, the control error can be kept at ≤±0.2°C. When the set value is 37°C and the ambient temperature is 23°C, the control accuracy can be guaranteed At ≤±0.1°C. Among them, St is the set temperature, t is the temperature in the box, EL is the lower limit value of the control output, EH is the upper li...

Abstract

The invention discloses a CO 2 The temperature control method of the incubator, including: according to the set temperature st and CO 2 The real-time temperature t inside the incubator is used to calculate the temperature control deviation value er; 2 The incubator temperature control method controls the output power of the heating element, controls the CO 2 The temperature t in the incubator is within the precise range. This method effectively avoids temperature overshoot, effectively controls the stability and uniformity of the box temperature, and ensures that different cells can be cultivated under different environmental conditions, making CO 2 When the incubator is in the environment of 15-35°C and the set temperature is 30-50°C, the control error can be kept at ≤±0.2°C. When the set value is 37°C and the ambient temperature is 23°C, the control accuracy can be guaranteed At ≤±0.1°C.

Description

technical field [0001] The invention relates to the field of incubator control, in particular to a CO 2 The temperature control method of the incubator. Background technique [0002] The carbon dioxide incubator is a device for culturing cells / tissues in vitro by simulating a growth environment similar to cells / tissues in organisms in the incubator. It is an advanced instrument for cell, tissue, and bacterial culture. It is the key equipment necessary for immunology, oncology, genetics and bioengineering. [0003] Research and production in scientific fields such as microbiology, medicine, pharmaceuticals, environmental protection, food, animal husbandry, etc. Commonly used in cell kinetics research, collection of mammalian cell secretions, carcinogenic or toxicological effects of various physical and chemical factors, research and production of antigens, cultivation of hybridoma cells to produce antibodies, in vitro fertilization (IVF), stem cells, tissues In research fi...
