Problems solved by technology

Although infrared sensing has the above advantages in temperature measurement, this type of sensor also has disadvantages such as low temperature measurement accuracy (compared with contact temperature measurement sensors), and large deviations in temperature measurement data between different sensors.

Abstract

The invention discloses a measurement device and a calibration method used for consistency calibration, wherein at least two control motors are disposed on a measurement support; an installation plate is disposed on a power output shaft of each control motor; an infrared measurement sensor is disposed on the installation plate; a calibration benchmark object is disposed on the measurement support; a contact-type high-precision sensor is disposed on the calibration benchmark object; and the contact-type high-precision sensor and the infrared measurement sensors are in a communication connection with a control center. The multiple infrared sensors measure different parts of the same object; good temperature measurement consistency is required between temperature measurement sensors; a benchmark temperature is determined at first by the contact-type high-precision sensor; then the benchmark temperature and temperature measurement data of the infrared temperature measurement sensors are compared one by one; a corresponding algorithm model is established; and the infrared temperature measurement sensors are finally used to carry out temperature measurement of the surface of the tested object, so that calibration errors among the different infrared measurement sensors are eliminated and temperature measurement accuracy is increased.

Description

technical field [0001] The invention relates to a measuring device and a calibration method for consistency calibration. Background technique [0002] At present, there are two main methods of temperature measurement: contact and non-contact. It is difficult to measure the temperature of the surface of a moving object, a small heat capacity, a very rapid temperature change, or a small object with a contact sensor. Generally, a non-contact measurement method is used. The most commonly used non-contact measurement method is infrared temperature measurement. Sensors, infrared temperature sensors can not only measure the temperature of the measured object, but also can be used to measure the temperature distribution in the temperature field. Non-contact measurement There is no contact between the measured object and its sensitive elements, so it is also called a non-contact temperature measuring instrument. The most frequently used non-contact thermometers work according to th...
