High-temperature furnace temperature measuring system capable of automatically correcting temperature

The invention discloses a high-temperature furnace temperature measurement system capable of automatically correcting temperature, and the system comprises a high-temperature furnace unit which is a closed cavity and is used for placing a sample and maintaining a constant environment; the execution unit is used for heating the high-temperature furnace body and processing the feedback temperature; the temperature thermocouple is used for measuring the in-situ temperature of the sample; the infrared temperature measurement system is used for measuring the temperature of a medium-high temperature section of the sample; the temperature processing unit is used for temperature fitting correction and data output; and after temperature data measured by the temperature measuring thermocouple and the infrared temperature measuring system are processed by the temperature processing unit, the in-situ temperature of the whole temperature section of the sample is fed back. The in-situ temperature of the sample is accuratel
