Problems solved by technology

[0002] During the temperature measurement process, the sensor must establish a thermal balance with the measured medium in order to measure the temperature change of the measured medium. Because the sensor package and product protection shell will affect the heat exchange, resulting in a longer response time of the sensor, the measured There is a certain delay (lag) time between the temperature and the actual temperature

Embodiment Construction

[0039] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0040] In one embodiment, such as figure 1 As shown, a method for quickly measuring temperature includes the following steps:

[0041] S1. Obtain the sampling data at the sampling time through the temperature sensor;

[0042] S2. Obtain the first data at the sampling moment, where the first data at the sampling moment is data obtained after the sampling data at the sampling moment undergoes adaptive low-pass filtering;

[0043] S3. Obtain second data at the sampling moment, where the second data at the sampling moment is data obtained after frequency expansion of the first data at the sampling moment;

[0044] S4. Obtain the third data at the sampling moment, where the third data at the sampling moment is the first correction amount after acceleration of the sec...

Abstract

The invention relates to a method and apparatus for rapidly measuring temperature. The method includes the steps of obtaining sampling data at a sampling time through a temperature sensor, obtaining first data at the sampling time, obtaining second data at the sampling time, obtaining third data at the sampling time, and conducting adaptive smooth processing on the third data at the sampling time to obtain the final data of the sampling time. Adaptive low-pass filtering, frequency expansion dynamic acceleration and adaptive smooth processing are conducted for sampling data output by the sensor, thereby substantially improving the sensitivity of temperature measurement.

Description

technical field [0001] The invention relates to a temperature measurement system, in particular to a method and device for rapidly measuring temperature. Background technique [0002] In the temperature measurement process, the sensor must establish a thermal balance with the measured medium to measure the temperature change of the measured medium. Because the sensor package and product protection shell will affect the heat exchange, resulting in a longer response time of the sensor, the measured There is a certain delay (lag) time between the temperature and the actual temperature. The time constant and lag time of the temperature sensor are related to the thermal capacity and thermal resistance of the temperature sensor. [0003] It is a very important issue to correctly understand and treat the time constant and hysteresis of the temperature sensor. It is related to whether the temperature can be measured correctly and the change of the measured temperature can be refle...
