Description

A kind of intelligent verification system and method of platinum resistance temperature sensor for meteorology

technical field

The invention relates to the field of temperature verification in the meteorological measurement industry, in particular to an intelligent verification system and method for a platinum resistance temperature sensor used in meteorology.

Background technique

Meteorological verification regulations "Platinum Resistance Temperature Sensor for Automatic Weather Station JJG (Weather) 002-2015" stipulates that the main technical requirement for the verification of temperature sensor of automatic weather station is to immerse the temperature sensor and standard thermometer to be tested in a constant temperature water tank or alcohol tank. After the temperature values of the standard thermometer and the measured temperature sensor are stable, take four readings on the temperature sensor and the standard thermometer in the tank. By comparing the measurement results of the temperature sensor and the standard thermometer, the measurement error of the temperature sensor can be calculated to determine whether the temperature sensor under test meets the performance requirements of meteorological measurement. At the same time, the regulations also make specific requirements for the selection of temperature verification points, which are -30 °C (-50 °C), 0 °C, 20 °C and 50 °C.

The technical solution commonly used by meteorological departments at all levels is to complete the verification of four temperature points in a constant temperature tank. The specific process is:

(1) Connect the tested sensor and standard thermometer to the temperature verification system, set the temperature of the alcohol in the constant temperature tank to be stable to 0°C, and immerse the tested temperature sensor and standard thermometer in the alcohol, and the system to be verified displays the tested temperature sensor and standard After the temperature value of the thermometer is stable, read it;

(2) Stabilize the temperature of the alcohol in the constant temperature bath to -30°C (-50°C), and read it after the verification system shows that the temperature values of the tested temperature sensor and the standard thermometer are stable;

(3) Replace the alcohol in the constant temperature tank with pure water, set the water temperature in the constant temperature tank to be stable to 20°C, and read it after the verification system shows that the temperature values of the tested temperature sensor and the standard thermometer are stable;

(4) Set the water temperature in the constant temperature tank to be stable to 50 °C, and read it after the verification system shows that the temperature values of the tested temperature sensor and the standard thermometer are stable;

(5) Compare the readings of the tested sensor at the four temperature points with the readings of the corresponding points of the standard thermometer, obtain the verification results such as the measurement error of the tested sensor, and judge whether the tested sensor can continue to be used in the automatic weather station.

Verifiers can perform batch verification through various temperature verification systems, and realize the automatic collection of temperature data and automatic processing of verification errors during the verification process. However, this working mode still has certain limitations. The first is the problem of verification efficiency. As automatic weather stations gradually replace manual conventional ground observation equipment, the number of annual inspections of temperature sensors in some provinces exceeded 3,000 by the end of 2018, and this data is still growing. Under the conditions of normal operation of the verification system, Only one batch of temperature sensors can be tested in batches per working day. The models of the test systems are different, and the number of testers for each batch is also different, about 20-32 per batch. The second is the problem of long manual waiting time. During the verification process, the temperature of the liquid medium in the constant temperature bath has a long stabilization time from one verification point to the next verification point, especially the cooling process of the liquid medium takes several hours, and in the verification process The liquid medium needs to be replaced manually. Finally, emerging technologies such as big data and artificial intelligence put forward higher requirements for meteorological measurement. At this stage, there are 4 temperature verification points required by relevant regulations and specifications, and only the corresponding 4 sets of values obtained during the verification process cannot be used for data fusion. , equipment fault diagnosis and other methods to provide data support. The above analysis shows that the existing technical solutions cannot meet the status quo of business growth, the temperature verification process is time-consuming and laborious, and the automation and intelligence level of the temperature verification system needs to be improved.

The arm 1 is positioned, grabs the first sensor container 9 and moves to the first constant temperature tank 3, and makes the first sensor container 9 enter the first constant temperature tank 3 through the first position recognition module, so that the alcohol in the tank is completely immersed in the first constant temperature tank 3. The platinum resistance probe in the sensor container 9; when the software control part 12 detects that the indication value of the standard thermometer 16 in the first constant temperature tank 3 reaches 0°C, the heating or cooling is stopped, and the temperature remains unchanged at 0°C, and the software control part 12 does not stop Receive the real-time temperature data measured by the measured sensor 14 in the first sensor container 9 collected by the terminal 13 and judge whether it is stable.

A sensor container 9 is moved into the second thermostatic bath 4 .

Step 4: According to the above steps, in the process of continuously moving from the first sensor container 9 to the fourth constant temperature bath, new sensor containers 9 are continuously put into the first constant temperature bath 3. In this way, four sensor containers are placed in the fourth constant temperature bath. One constant temperature tank 3 to the fourth constant temperature tank 6 form a water flow test. After the verification is completed, the four sensor containers 9 are placed in the third type of placement container 11 one by one.
