Description

Meteorological platinum resistance temperature sensor intelligence verification system

Technical Field

The utility model relates to a temperature examination field in meteorological measurement industry, concretely relates to platinum resistance temperature sensor intelligence verification system for meteorological affairs.

Background

The weather verification regulation JJG (weather) 002-2015 stipulates that the automatic weather station temperature sensor verification has the main technical requirements that the temperature sensor to be detected and a standard thermometer are immersed in a constant-temperature water tank or an alcohol tank, and the temperature sensor and the standard thermometer in the tank are read for four times after the temperature values of the standard thermometer and the measured temperature sensor are stable. The measurement error of the temperature sensor can be calculated by comparing the measurement results of the temperature sensor and the standard thermometer, so that whether the detected temperature sensor meets the meteorological measurement performance requirement or not is judged. At the same time, the protocol also makes specific requirements for the selection of the temperature detection points, namely-30 ℃ (-50 ℃), 0 ℃, 20 ℃ and 50 ℃.

The technical scheme commonly used by all levels of meteorological departments is to finish the verification of four temperature points in a constant temperature bath. The specific process is as follows:

(1) connecting the detected sensor and the standard thermometer into a temperature detection system, setting the temperature of alcohol in a constant temperature bath to be stable to 0 ℃, immersing the detected temperature sensor and the standard thermometer into the alcohol, and reading the detected temperature sensor and the standard thermometer after the detected system displays that the temperature values of the detected temperature sensor and the standard thermometer are stable;

(2) stabilizing the temperature of alcohol in the thermostatic bath to-30 ℃ (-50 ℃), displaying the temperature values of the detected temperature sensor and the standard thermometer by the system to be detected to be stable, and reading the temperature values;

(3) replacing alcohol in the thermostatic bath with pure water, setting the water temperature in the thermostatic bath to be stable to 20 ℃, and displaying the temperature values of a detected temperature sensor and a standard thermometer by a system to be detected to be stable and then reading the temperature values;

(4) setting the water temperature in the thermostatic bath to be stabilized to 50 ℃, and displaying the temperature values of the detected temperature sensor and the standard thermometer by the system to be detected to be stable and then reading the temperature values;

(5) and comparing the readings of the detected sensor at the four temperature points with the readings of the corresponding points of the standard thermometer to obtain detection results such as measurement errors of the detected sensor, and judging whether the detected sensor can be continuously used in the automatic weather station.

The verification personnel can perform batch verification through various temperature verification systems, automatic acquisition of temperature data and automatic processing of verification errors in the verification process are realized, and the working mode still has certain limitation. Firstly, the problem of verification efficiency is solved, as an automatic weather station gradually replaces manual conventional ground observation equipment, the annual verification number of the temperature sensors in the province of 2018 exceeds 3000, the data is still continuously increased, and under the condition that a verification system normally operates, only one batch of temperature sensors can be verified in batches every working day, the models of the verification systems are different, the verification number of each batch is also different, and each batch is about 20-32. Secondly, the problem of long manual waiting time is that the stability time of the temperature of the liquid medium in the thermostatic bath from one detection point to the next detection point is long in the detection process, especially the temperature reduction process of the liquid medium needs several hours, and the liquid medium needs to be replaced manually in the detection process. And finally, the problem that emerging technologies such as big data, artificial intelligence and the like provide higher requirements for meteorological measurement is solved, 4 temperature detection points are required by relevant regulation specifications at the present stage, and only 4 corresponding groups of values are obtained in the detection process, so that data support cannot be provided for methods such as data fusion, equipment fault diagnosis and the like. The analysis shows that the existing technical scheme cannot meet the current situation of service growth, the temperature verification process is time-consuming and labor-consuming, and the automation and intelligence level of the temperature verification system needs to be improved.
