Temperature control method and system

Abstract

The invention relates to a temperature control method and system. The method comprises acquiring a first temperature signal output by a first temperature sensor used for detecting the temperature in areagent chamber, acquiring a second temperature signal output by a second temperature sensor used for detecting the temperature of a heat dissipating module, acquiring a first temperature value according to the first temperature signal, acquiring a second temperature value according to the second temperature signal, and when the first temperature value is greater than a first preset threshold andthe second temperature value is less than a fourth preset threshold, controlling the work of a cooling sheet. The method and system can keep the reagent chamber temperature in a desired temperature range and in a stable state and guarantee the effectiveness of the chemical reagent.

Description

technical field [0001] The invention relates to clinical diagnostic equipment, in particular to a temperature control method and system. Background technique [0002] The automatic chemiluminescence immunoassay analyzer combines highly sensitive chemiluminescence assay technology with a highly specific immune response, and is used for the detection and analysis of patients' serum, saliva, urine, etc., such as antigens, haptens, antibodies, hormones , enzymes, fatty acids, vitamins and drugs and other indicators, so that the fully automated medical testing equipment for immune analysis of the human body plays an important role in clinical diagnosis and chemical testing. After fluorescence immunoassay, radioimmunoassay, and enzyme immunoassay, chemiluminescence immunoassay reagent (CLIA) was developed. As a high-sensitivity clinical diagnostic reagent, factors affecting the quality and characteristics of chemiluminescence instruments in the process of use numerous. [0003] ...

AI Technical Summary

Problems solved by technology

[0004] At present, semiconductor refrigeration technology is generally used, such as Peltier. Peltier cools at one end while the other end heats up, but the reagent compartment has no overheat protection function for the hot end, or uses a temperature sensor to achieve overheat protection. If the temperature sensor fails, Peltier The sticker will always work at maximum power, there is a risk of overheating

Moreover, in the process of temperature control, generally only Peltier control measures are taken, and the fan runs at full speed during the heat dissipation process, and the noise generated is relatively large.
