Abstract

The invention discloses a temperature detecting system based on an interference eliminating circuit. The temperature detecting system is mainly composed of a processing chip U1, a temperature sensor U, the interference eliminating circuit which is connected with an IN+ pin of the processing chip U1, a base electrode triggering circuit which is serially connected between the temperature sensor U and the interference eliminating circuit, and a capacitor C4 of which the anode is connected with the V+ pin of the processing chip U1 through a resistor R9 and a resistor R8 and the cathode is connected with the BALANCE pin of the processing chip U1. The temperature detecting system can process the frequency of a detecting signal so that the frequency of the detecting signal is more stable, thereby keeping consistency between the waveform of an input detecting signal and the waveform of an output detecting signal, keeping fidelity of the detecting signal and preventing temperature detecting precision reduction caused by signal distortion.

Description

technical field [0001] The invention relates to a detection system, in particular to a temperature detection system based on an interference elimination circuit. Background technique [0002] In the industrial production process and scientific research work, it is often necessary to detect the temperature of the production equipment or the production environment and control the temperature according to the demand, so as to improve the production efficiency and product quality. However, the existing temperature detection system tends to distort the detection signal when processing the detection signal, so that it cannot accurately detect the temperature value and cannot meet the production requirements. Contents of the invention [0003] The purpose of the present invention is to overcome the defect that the current temperature detection system easily distorts the detection signal when processing the detection signal, and provides a temperature detection system based on an ...
