Thermal parameter measuring method, device and thermal sensation sensor

Abstract

The invention provides a thermal parameter measuring method, device and a thermal sensation sensor. The method comprises steps: the voltage and the current when the thermal sensation sensor is contacted with a to-be-measured object are acquired, and according to the voltage and the current, the resistance when the thermal sensation sensor is contacted with the to-be-measured object is determined;according to the resistance and a pre-calibrated and obtained thermal sensation sensor resistance and temperature relationship, the actually-measured temperature of the contact surface between the thermal sensation sensor and the to-be-measured object is determined; and according to the relationship of the temperature along with changes of time when the thermal sensation sensor is contacted with the to-be-measured object and the actually-measured temperature of the contact surface between the thermal sensation sensor and the to-be-measured object, the thermal parameters of the to-be-measured object are obtained, wherein the relationship of the temperature along with changes of time is solved through a heat transfer model. The above technical scheme realizes the quantitative measurement ofthe thermal parameters of the to-be-measured object.

Description

technical field [0001] The invention relates to the technical field of thermal parameter measurement, in particular to a method, device and thermal sensor for measuring thermal parameters. Background technique [0002] With the development of microcomputer and Internet of Things technology and the implementation of Industry 4.0, sensors, as the basis of Internet of Things perception signals, are getting more and more attention and development. [0003] The tactile sensor imitates the complex sensing system of the human skin, and can detect many important signals such as pressure, temperature, texture, vibration, etc., among which the thermal sensor is an important part, and the information is obtained through the contact between the sensor and the object. In the following three aspects: obtain temperature information, such as electronic skin temperature measurement for health monitoring, robots perceive environmental temperature, etc.; obtain other information through temper...
