Problems solved by technology

Although the collected temperature of some temperature acquisition devices can be accurate to 0.1 degrees Celsius, it is difficult to adjust the temperature of the entire system accurately following the temperature change of the heated object, resulting in a large temperature error between the system temperature and the target temperature

Abstract

The invention relates to a temperature control system comprising a temperature measuring circuit, a control circuit, and an execution circuit. The temperature measuring circuit is used for carrying out periodic measurement on a temperature of a target object, generating a voltage signal, and outputting the signal. The control circuit connected with the temperature measuring circuit is used for receiving the voltage signal, obtaining a current temperature value of the target object based on the voltage signal, and setting heating time based on a preset target temperature value and the current temperature value, wherein the heating time is less than or equal to a measurement period of the temperature measuring circuit. The execution circuit connected with the control circuit is used for controlling a heating device to carry out heating according to the heating time, thereby realizing temperature adjustment of the target object. The temperature control system can detect the temperature of a target object periodically and set the conduction time of the heating device within the measurement period based on the detection time, thereby realizing temperature adjustment. The output is adjusted correspondingly with the temperature change of the target object, so that the temperature adjustment precision is improved and the temperature error is reduced.

Description

technical field [0001] The invention relates to the technical field of temperature control, in particular to a temperature control system. Background technique [0002] There are different degrees of temperature errors in traditional temperature control systems (such as in the heat preservation platform). Although the collected temperature of some temperature acquisition devices can be accurate to 0.1 degrees Celsius, it is difficult to adjust the temperature of the entire system accurately following the temperature change of the heated object, resulting in a large temperature error between the system temperature and the target temperature . Contents of the invention [0003] Based on this, it is necessary to provide a temperature control system with a small temperature error to solve the above problems. [0004] A temperature control system, comprising: a temperature measurement circuit for periodically measuring the temperature of a target object and outputting a volta...
