Non-contact online temperature measurement method and system

Abstract

The invention discloses a non-contact online temperature measurement method and system. The method comprises the following steps: enabling a thermal conduction differential equation temperature resolving module built according to the principles of heat transfer to be placed in a data processing unit; enabling the data processing unit to be connected with a temperature collection device and an upper computer; enabling the data processing unit to receive the environment temperature data, collected by the temperature collection device, of the surroundings of a measured object after connection; enabling the temperature resolving module in the data processing unit to resolve the change process of the temperature of the measured object along with time according to the sampled environment data of the surroundings of the measured object; and enabling the upper computer to store, display, analysis and monitor the temperature of the measured object through receiving the change process, transmitted from the data processing unit, of temperature along with time. According to the invention, through the collection of the environment temperature data of the surroundings of the measured object, the method resolves the temperature of the measured object in real time through employing the temperature resolving module based on the thermal conduction differential equation, and is suitable for the temperature detection of the detected object with the internal temperature not being convenient to measure directly.

Description

technical field [0001] The invention relates to the technical field of measurement and control, in particular to a non-contact online temperature measurement method and system. Background technique [0002] In the production and management process of machinery industry, chemical industry, national defense industry and other fields, it is often necessary to monitor the internal temperature field of processed products or stored and managed items in real time to eliminate potential safety hazards and promote safe production and safety management. Reduce unnecessary personal and economic losses. For example, monitor the real-time temperature in the acid, alkali, salt, oil and chemical dangerous goods storage tanks (towers, cylinders) to eliminate dangerous (point) sources; monitor the temperature of grain in the warehouse so that it will not germinate and deteriorate; monitor propellants, etc. The internal temperature change of the solid fuel prevents spontaneous combustion, et...

AI Technical Summary

Problems solved by technology

A common feature of this type of temperature measurement problem is that the internal temperature of the measured object cannot be directly measured.

[0003] The traditional methods include thermocouple temperature measurement, infrared temperature measurement, spectral temperature measurement, etc. Some of these methods need to open holes for measurement, and some can only measure the surface temperature. They must directly contact the measured object, and manual recording of data is time-consuming and expensive Important data may be missed, and 24 / 7 automatic detection is not possible
