Abstract
The invention discloses a kind of automatic calibrating method of the temperature transmitter based on discrete analysis, its numerical value that can be detected during temperature transmitter is operated to it is analyzed in real time, by judging that the Temperature numerical of above-mentioned detection is that to belong to temperature caused by unit exception in environment abnormal vertically for the temperature Discrete Change trend in normal operation of temperature in environment, also or factor change in environment periphery causes variation of ambient temperature and causes Temperature numerical anomaly, and then temperature transmitter is caused to realize the judgement to abnormality simultaneously in detection process, to improve its operating accuracy.
Description
Technical field
The present invention relates to electronic technology field, the automatic calibration side of especially a kind of temperature transmitter based on discrete analysis
Method.
Background technology
Transmitter is that physical measurement signal or generic telecommunication number are converted to standard electric signal output by one kind, or with communication
The equipment of protocol mode output.Temperature transmitter is one of common transmitter, its temperature change shape being used to detect in environment
State.Existing temperature transmitter is only capable of single reaction, and it detects Temperature numerical in environment, but the temperature anomaly in environment can
It can form for different reasons, the above-mentioned variation tendency of reaction that existing temperature transmitter can not be good, therefore its accuracy of detection
Exist bad.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of automatic calibrating method of temperature transmitter, and it can be by discrete
The mode of analysis is to detect the judgement of temperature anomaly reason in environment for temperature transmitter, to improve the work of temperature transmitter
Make precision.
In order to solve the above technical problems, the present invention relates to a kind of automatic calibration side of the temperature transmitter based on discrete analysis
Method, including have the following steps：
1) its local environment multiple detection numerical value in the detection cycle of setting are recorded by temperature transmitter, by above-mentioned multiple inspections
Numerical value is surveyed to be stored among temperature transmitter；The variance between above-mentioned multiple detection numerical value is calculated to obtain detection variance yields, will
Detection variance yields is recorded among temperature transmitter；The detection cycle is 4 to 5h；
2) when the arbitrary temp numerical value that temperature transmitter detects in environment in the course of the work exceedes given threshold, temperature becomes
After sending device to record Temperature numerical generation automatically, multiple Temperature numericals of its local environment in calibration cycle are to be used as calibration number
Value；The calibration cycle is 40 to 80s；
3) calculation procedure 2）In multiple calibration figures calibration variance yields, by above-mentioned calibration variance yields and step 1）Among inspection
Survey variance yields to be compared, if calibration variance yields is more than detection variance yields, temperature transmitter is normally by step 2）Middle detection
The Temperature numerical arrived carries out alert process, if calibration variance yields is less than or equal to detection variance yields, then temperature transmitter continues weight
The acquisition of a multiple calibration cycle internal calibration numerical value is with comparing.
Using the automatic calibrating method of the temperature transmitter based on discrete analysis of above-mentioned technical proposal, it can become in temperature
The numerical value for sending device to be detected during being operated to it is analyzed in real time, by for temperature in environment in normal operation
Temperature Discrete Change trend to judge that the Temperature numerical of above-mentioned detection is to belong in environment that temperature is erected caused by unit exception
Straight abnormal, also or factor change in environment periphery causes variation of ambient temperature and causes Temperature numerical anomaly, and then causes temperature
Degree transmitter can realize the judgement to abnormality simultaneously in detection process, to improve its operating accuracy.
