Description

High-precision airborne meteorological monitoring integrated device for unmanned aerial vehicle Technical Field The invention belongs to the technical field of unmanned aerial vehicle weather acquisition, and particularly relates to a high-precision airborne weather monitoring integrated device for an unmanned aerial vehicle. Background Meteorological has important influence on human life and agricultural production, and a meteorological station is a main device for monitoring meteorological conditions, so that today meteorological data acquisition mainly depends on fixed meteorological observation equipment or unpowered air-floating balloons on the ground, only some meteorological data on the ground and near a specific height can be monitored, and the meteorological data of a certain height and a certain area in the air can not be monitored flexibly in real time. Although the manned fixed wing aircraft can collect high-altitude meteorological data, the unmanned fixed wing aircraft has the defects of high cost, short collection time, difficult track planning, few types of collected data, high risk of crewmembers in severe weather and the like. Currently, when an unmanned aerial vehicle is applied to weather monitoring, two modes are generally adopted, namely, a single-function weather sensor (such as a temperature probe) is carried, limited parameters can be obtained only, the data comprehensiveness is insufficient, and a plurality of independent commercial miniature sensors (such as temperature, relative humidity and air pressure sensors) are simply bundled and then are mounted on an unmanned aerial vehicle body or a landing gear. The sensors usually come from different manufacturers and work independently of each other, data are respectively transmitted to a flight control computer or a ground station through respective data lines or wireless modules, and then data summarization and simple processing are carried out by software, so that the combination mode only realizes the physical concentration of equipment, but not the real system integration. At present, each data acquisition module of the existing airborne weather monitoring integrated device independently works and is connected with a host through a lead, so that the device is not only disordered and unordered, but also inconvenient to install and influence the flight safety, and inconvenient to use. The method has the advantages that the method is low in integration level, the flying performance is affected, the integral load is large in size and large in weight due to a plurality of independent devices and connecting cables and power supplies of the independent devices, the aerodynamic appearance is poor, the power consumption of the unmanned aerial vehicle is obviously increased, the effective endurance time of the unmanned aerial vehicle is shortened, the flying stability and operability are possibly affected, the data synchronism and the fusion performance are poor due to multi-channel acquisition and transmission, each sensor is independently acquired and independently transmitted, the problems of asynchronous time stamps and inconsistent sampling frequencies exist, the acquired multi-element meteorological data are difficult to accurately match on a space-time reference, the later data fusion analysis and construction of a refined meteorological model are difficult, the monitoring precision is affected, the installation layout is not scientific, the mutual interference is large, and the influence of electromagnetic interference and thermal interference among the sensors and the influence of the unmanned aerial vehicle body (such as propeller airflow and motor heating) on the measurement accuracy is not fully considered due to simple binding installation. For example, if the anemometer is installed in a propeller turbulence area, the measured value will be severely distorted, the electronic device heating will affect the reading of a nearby temperature sensor, the exposed cable and a plurality of plug-ins are easy to loose and damage in a complex flight environment, the failure rate is high, the daily calibration, maintenance and upgrading and replacement are very inconvenient due to the module dispersion, the function expansibility is weak, the existing loose structure is difficult to integrate new detection modules (such as a visibility meter and a particulate matter sensor) conveniently, and the system upgrading and customizing capability is insufficient. Disclosure of Invention First, the technical problem to be solved The technical problem to be solved by the invention is how to overcome the defects of the prior art, and how to provide a high-precision airborne weather monitoring device for an unmanned aerial vehicle, and how to realize the deep integration of six meteorological elements (temperature, relative humidity, visibility, air pressure, wind direction and wind speed) detection equipment through a high-integration and modularized
