One-button humidity sensor field calibration system and method suitable for deep ocean buoy

Abstract

The invention dislcoses a one-button humidity sensor field calibration system and method suitable for a deep ocean buoy. The one-button humidity sensor field calibration system comprises a controller,wherein the controller is connected with a first humidity sensor and a second humidity sensor; the first humidity sensor and the second humidity sensor are both mounted on the deep ocean buoy; the controller is also connected with an iridium satellite module; through data collected by the first humidity sensor and the second humidity sensor, the controller sends a humidity sensor calibration request to a satellite through the iridium satellite module, and the satellite forwards the calibration request to an iridium satellite module of a shore station; the controller starts one-button calibration on one humidity sensor according to a calibration command; through controlling motion of a triaxial manipulator, the controller grabs one humidity sensor to be calibrated through a clamping jaw, and performs preprocessing; through controlling motion of the triaxial manipulator, the controller grabs the humidity sensor to be calibrated through the clamping jaw, puts into a humidity generator and starts calibration work. The one-button humidity sensor field calibration system and method can be used for achieving one-button field calibration on the deep ocean buoy.

Description

technical field [0001] The invention relates to the field of marine meteorological monitoring, in particular to an on-site calibration system and method for a one-button humidity sensor suitable for deep-sea buoys. Background technique [0002] According to the conditions of use of the eddy correlation method, the calculation of the air-sea flux requires high-precision measurement data, such as: high-precision temperature, humidity, pressure and rainfall data; [0003] Humidity measurement data needs to be collected by a humidity sensor; as the working time of the sensor increases, the measured data will drift accordingly, so it is hoped that a short-term calibration can improve the accuracy of the measurement data, but for the deep sea field, especially for water depths of 4000 meters In the following deep-sea fields, the existing technology is to install humidity sensors on deep-sea buoys. The buoys are far away from the land. The cost of the fleet going to sea once is too...

Problems solved by technology

[0004] First, the cost of going to sea for the fleet is as high as 7.5 million to 10 million yuan. If the humidity sensor is calibrated to go to sea once a year, the cost of going to sea will be wasted;

[0005] Second, the current situation of marine humidity sensor calibration is manual calibration, which is inefficient and has the possibility of misoperation, resulting in inaccurate calibration; the existing technology has certain deficiencies in the processing of calibration accuracy, and marine humidity sensors work in marine environments. , different from the land environment, the humidity sensor will face the particularity of the environment when used in the ocean, including strong corrosion, high humidity, wind speed 25% higher than that on land, and humidity sensors are often integrated on platforms such as buoys or ships and swing with the platform, etc. , the complex working environment brings high requirements for the fast and accurat
