Abstract

Disclosed in the invention is a temperature control system comprising a control unit, a drive module, a thermoelectric cooler (TEC), and a ceramic heating plate. The control unit, the TEC, and the ceramic heating plate are connected with the drive module; and the TEC and the ceramic heating plate are connected with a controlled object. The control unit is used for obtaining a real-time temperature value of the controlled object, obtaining a temperature control signal according to the real-time temperature value and a target temperature value, and sending the temperature control signal to the drive module. The drive module is used for driving the TEC based on the temperature control signal to enable the TEC to cooling the controlled object or is used for driving the ceramic heating plate according to the temperature control signal to enable the ceramic heating plate to heat the controlled object. According to the invention, the temperature of the controlled object is controlled under the joint effect of the TEC and the ceramic heating plate. Compared with the way of controlling the temperature of the controlled object by cooling and heating of the TEC in the prior art, the provided temperature control system has advantages of high control precision and wide temperature control range.

Description

technical field [0001] The invention relates to the field of temperature control, in particular to a temperature control system. Background technique [0002] TEC, also known as semiconductor cooler, is a new type of cooling function device, which is often used in occasions with limited space and high reliability. The output of cooling capacity is controlled by controlling the magnitude of the current flowing through the semiconductor refrigerator. The semiconductor refrigerator has the characteristics of simple structure, no wear, good reliability, long life, quick start, flexible control and high precision. [0003] Changes in temperature will bring major changes to our life, work, and production, so the measurement of temperature is very important. Its measurement and control instruments use various temperature sensors. With the development of modern computer and automation technology, as a functional device for the perception, collection, conversion, transmission and ...
