Temperature control method and system

Abstract

The invention discloses a temperature control method and system. The temperature control method includes the following steps that: when each electric oven carries out heating each time, a temperature rise delay difference value in a current heating process is calculated automatically according to a current use environment, wherein the temperature rise delay difference value is the difference value of a temperature value detected by a temperature sensing bulb and an actual temperature value; and temperature fed back by the temperature sensing bulb is compensated with the temperature rise delay difference value adopted as a temperature compensation value. According to the temperature control method and system of the invention, when each electric oven carries out heating each time, the temperature rise delay difference value is calculated independently according to the current use environment, and test data are not required to be collected at an early stage, and thus, compared with a method in the prior art according to which segmental compensation is adopted, the temperature control method of the invention can ensure the accuracy of a temperature compensation value under conditions that relevant materials change such as conditions that temperature sensing bulb material changes, temperature sensing bulb parameters are adjusted, the use environments of electric ovens changes, and user settings are changed, and can assist in greatly reducing workload.

Description

Technical field [0001] The present invention relates to the technical field of temperature control, and more specifically, to a temperature control method and system. Background technique [0002] At present, the method of controlling the heating temperature of the electric oven is: when the heating tube in the oven is heated, the temperature sensor will detect the temperature value in the electric oven in real time, and feedback the temperature value to the controller, and the controller will feedback the temperature sensor The temperature value is compared with the user set temperature value. When the temperature value is lower than the user set temperature value, the controller continues to control the heating of the heating tube. When the temperature value reaches or exceeds the user set temperature value, the controller controls the heating The tube is powered off to stop heating to ensure the consistency of the user's set temperature value with the actual temperature value ...

AI Technical Summary

Problems solved by technology

In order to ensure the accuracy of the relevant temperature, it is necessary to simulate various situations in the early stage and do a large number of experimental tests to extract data, and once there is a change in related materials (such as a change in the temperature sensor parameters), a large number of experiments must be done again to verify and confirm. Therefore, the existing temperature compensation method has a large workload

In addition, since the difference obtained in the experiment is for all temperature-sensing packages with a detection temperature in a certain temperature range, and there will be certain differences between temperature-sensing packages of different models and batches, the actual ambient temperature of the electric oven is compared with The temperature during the experiment also has certain fluctuations, therefore, there is still a certain error in the temperature compensation value obtained by using the existing temperature compensation method
