Abstract

The invention discloses a temperature control system with an environment temperature compensating function. According to change of an environment temperature, the system actively changes a temperature of a reaction disc, and compensates influence of the environment temperature to a reaction solution temperature. The system comprises a reaction disc temperature detection circuit used for detecting a reaction disc temperature. The reaction disc temperature detection circuit connects with a one-chip microcomputer through a first A/D conversion module. The one-chip microcomputer connects with a drive circuit. The drive circuit connects with a heating plate. The heating plate is provided around the reaction disc. The reaction disc is embedded with a reaction cup and heats reaction solution in the reaction cup. The system also comprises an environment temperature detection circuit used for detecting the environment temperature. The environment temperature detection circuit connects with the one-chip microcomputer through a second A/D conversion module. According to the temperature control system of the present invention, requirements of high precision, fast response and good stability of temperature by a biochemistry analyzer are satisfied, and environmental adaptability of a device is improved.

Description

[0001] technical field [0002] The invention relates to a temperature control system, in particular to a temperature control system with an environment temperature compensation function. Background technique [0003] The temperature control system is an important part of the biochemical analyzer. Only when the tested samples and reagents are tested at the specified temperature can the reliability of the biochemical test results be guaranteed. At present, the main temperature control methods used in biochemical analyzers include air bath, water bath, constant temperature liquid bath, solid dry bath and Peltier effect sheet. Among them, the solid direct heating constant temperature system has many advantages, such as strong heat storage capacity of the reaction plate, rapid heat conduction, stable and uniform temperature, fast temperature rise of the reaction liquid, and convenient maintenance. Therefore, solid direct heating constant temperature systems are increasingly use...
