Abstract
A high-temperature warning circuit with compensation correction comprises a temperature sensor and a temperature detection module connected with the signal output end of the temperature sensor. The temperature detection module realizes the conversion from temperature signals to electrical signals. The output of the temperature detection module is connected with an amplification circuit. The output of the amplification circuit is connected with a display module and a warning module. An amplification module is connected with a correction module for compensating distortion. Through the correction compensation for the distortion of the amplification portion, the accuracy in temperature detection is guaranteed.
Description
Technical field
The present invention relates to temperature monitoring early warning technology field, particularly a kind of high temperature warning circuit with compensation correction.
Background technology
In current temperature detection technology, how research emphasis is placed on to obtaining with system-level processing stage of signal, has ignored amplifying element.Cause in existing scheme, the working range of amplifying circuit is smaller, makes the temperature distortion detecting.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the object of the present invention is to provide a kind of high temperature warning circuit with compensation correction.
To achieve these goals, the technical solution used in the present invention is:
A kind of high temperature warning circuit with compensation correction, comprise the temperature detecting module of temperature sensor and jointing temp sensor signal output terminal, temperature detecting module realizes the transformation of temperature signal to electric signal, the output of temperature detecting module connects amplifying circuit, the output of amplifying circuit connects display module and alarm module, and described amplification module is connected to the correction module into its compensating distortion.
Compared with prior art, the present invention, by the distortion correction compensation to amplifier section, guarantees the accuracy of detected temperatures.
Accompanying drawing explanation
Accompanying drawing is structural representation of the present invention.
Embodiment
Below in conjunction with drawings and Examples, the present invention is carried out to more detailed explanation.
As shown in the figure, the present invention is a kind of high temperature warning circuit with compensation correction, comprise the temperature detecting module of temperature sensor and jointing temp sensor signal output terminal, temperature detecting module realizes the transformation of temperature signal to electric signal, the output of temperature detecting module connects amplifying circuit, the output of amplifying circuit connects display module and alarm module, and described amplification module is connected to the correction module into its compensating distortion.Wherein display module and alarm module are connected with control panel, in order to complete, high temperature warning value and warning volume and type are arranged.
In this programme, signal starts to form the transformation of thermal signal to electric signal by temperature sensor and temperature detecting unit most, is converted into after electric signal, the ability of electric signal is very little, need to carry out amplifying signal by amplifying circuit, make it to drive show and report to the police, and and control panel exchange message.
In whole link, correcting circuit is key component, is related to stability and the correctness of temperature detection value, and its principle is the duty according to amplifying circuit, gives the circuit part of amplifying circuit compensating distortion, guarantees that through amplifying signal be accurately.
