Device and method for forecasting freezing on surface of ground plane based on multisensor

Abstract

The invention provides a device and a method for forecasting freezing on the surface of a ground plane based on a multisensor. The device comprises a simulated plane wing, multiple temperature sensors, a temperature signal conditioning board, a humidity sensor, a humidity signal conditioning board, a wind speed sensor, an RS-485 serial communication interface and a computer system. In the device and method for forecasting freezing on the surface of the ground plane based on the multisensor provided in the invention, ice and snow weather forecast data of the airport region are combined with factors such as surface temperature of ground objects, atmosphere humidity and wind speed and the like to be served as input of mathematical model of the freezing forecast on the surface of the ground plane; the probability of freezing currently and in a short time in the future can be obtained through neural network forecast algorithm, therefore a short-time forecast can be conducted on freezing on the surface of the ground plane in the small region of the airport, timely monitoring can be carried out on the overnight planes on the parking apron so as to give freezing early warning signals in advance, thus being convenient for ground service departments in the airport to carry out deicing work in advance.

Description

technical field [0001] The invention belongs to the technical field of civil aviation, and in particular relates to a multi-sensor-based device and method for forecasting icing on the surface of an aircraft on the ground. Background technique [0002] At present, with the rapid expansion of my country's civil aviation transportation, the density of flight departures and landings has further increased. In order to ensure flight safety and efficient transportation of passengers, and reduce flight delays or cancellations caused by severe weather (ice, snow, freezing rain), weather forecasts in severe weather environments are of great significance to airport ground service support. [0003] Airport-wide meteorological forecasts are mainly provided by the airport meteorological department. Due to the large scope and long time of the forecast, and the forecast can only be made for atmospheric conditions, it cannot provide short-term forecasts for the icing conditions on the surfac...

AI Technical Summary

Problems solved by technology

Due to the large human factors and no scientific basis of this forecasting method, it is easy to have false positives and missed negatives, which can easily lead to flight safety accidents.

In addition, since this forecast method is actually an ex post forecast, it is not conducive to the airport ground service personnel to start the deicing procedure in advance, and it is also difficult for the management department to effectively organize resources such as personnel, equipment and materials to carry out deicing efficiently
