Abstract

The application discloses an intelligent temperature monitoring system based on NTC thermistor, and particularly relates to the technical field of temperature monitoring, and comprises a parameter configuration module, a voltage separation module, a temperature correction module, a feature extraction module and a report generation module, wherein the parameter configuration module controls an excitation source to generate a composite excitation signal according to parameters, and applies the composite excitation signal to the NTC thermistor, so as to establish a special excitation state acting on the sensor and the environment; the voltage separation module is used for synchronously acquiring total response voltage generated by the thermistor under the special excitation state, and separating the total response voltage into direct current response voltage and alternating current characteristic voltage; the temperature correction module is used for deducing a current temperature parameter according to the direct current response voltage and a standard electrothermal relationship of the thermistor; through the construction of a multi-module cooperative working mechanism under the composite excitation state, the dual improvement of temperature monitoring precision and environmental state sensing capability is realized.
