Temperature transmitter measurement error intelligent verification and analysis system

Abstract

The invention discloses a temperature transmitter measurement error intelligent verification and analysis system, which is used for verifying and analyzing measurement errors of a temperature transmitter to be verified. The system comprises a standard signal source, a data acquisition card and an intelligent verification terminal. The input end of the temperature transmitter to be verified is connected with the standard signal source, and the output end thereof is connected to the intelligent verification terminal through the data acquisition card. The standard signal source comprises an adjustable resistance standard source, an adjustable voltage standard source and an adjustable current standard source. The intelligent verification terminal comprises a parameter setting module and a result analysis module. The parameter setting module is used for generating a control signal according to test parameters set by a user and transmitting the control signal to the standard signal source; and the result analysis module is used for calculating the measurement errors. The provided temperature transmitter measurement error intelligent verification and analysis system realizes automatic verification of the temperature transmitter and is efficient and accurate.

Description

technical field [0001] The invention relates to an intelligent error calibration and analysis system, in particular to an intelligent calibration and analysis system for measuring the error of a temperature transmitter. Background technique [0002] A temperature transmitter is an instrument that converts a temperature variable into a transmittable standardized output signal. It is mainly used to measure the oil temperature of the main transformer of the power system. According to the requirements of the specification for the use of the temperature transmitter, it needs to be inspected periodically to ensure that the accuracy of the temperature transmitter meets the requirements. At present, the annual inspection workload of temperature transmitters is heavy. At present, the existing temperature transmitter calibration instrument can only calibrate a single transmitter at a time, and requires manual real-time operation and recording, and the calibration time is long; at the...
