Acquisition system of atmospheric profile parameters including temperature, humidity and pressure

Abstract

The invention discloses an atmospheric profile parameter acquisition system. The system includes a captive balloon, a coordinator, a receiving terminal and at least one group of acquisition unit. The at least one group of acquisition unit is sequentially fastened on the captive rope of the captive balloon; the acquisition unit includes a router and multiple acquisition nodes connected sequentially; the acquisition nodes are for the acquisition of three meteorological parameters including temperature, humidity and air pressure of an atmospheric profile, whose height the acquisition nodes are on; the router is used to collect the meteorological parameters of all acquisition nodes in the unit, in which the router locates; a coordinator and the router of the acquisition unit are in a wireless network; the coordinator receives meteorological parameters collected by each router and forwards the meteorological parameters to the receiving terminal. The system of the invention can realize real-time acquisition of three meteorological parameters including temperature, humidity and air pressure of the sea surface on the same longitude and latitude and obtain gradient distribution values concerning the three meteorological parameter values of the profile, and is conductive to accurate prediction of the time and region of atmospheric duct.

Description

technical field [0001] The invention relates to the technical field of marine atmospheric waveguide monitoring, in particular to an atmospheric profile parameter acquisition system for measuring atmospheric temperature, humidity and air pressure at different heights at the same longitude and latitude on the low-altitude sea surface. Background technique [0002] The monitoring and application of atmospheric ducts at sea is one of the important guarantees for improving marine security and protection capabilities. Direct detection, indirect detection and remote sensing detection are three methods of atmospheric duct measurement. A microwave refractometer is a device that directly measures the refractive index of the atmosphere. Since Bean and Dutton proposed the relationship between atmospheric refraction index and water pressure, air temperature and air pressure in 1968, atmospheric refraction index can also be obtained indirectly by measuring meteorological parameters.

Problems solved by technology

For example, in this scheme, each node directly communicates with the coordinator network, the communication distance is short, and the measurement height is limited; in different atmospheric temperature and humidity pressure ranges, the measurement results of the same sensor fluctuate greatly, and how to overcome the fluctuations remains to be solved ;Network communication between the collection nodes and the coordinator, the collection nodes
