ADS-B signal transceiving device

Abstract

The invention discloses an ADS-B signal transceiving device which comprises a parabolic plate, a supporting rod and an antenna, wherein one end of the supporting rod is connected with the antenna, and the other end of the supporting rod is connected with the parabolic plate. The ADS-B signal transceiving device further comprises a box body, a first telescopic pipe is arranged in the box body, a first ball body is arranged at the telescopic end of the first telescopic pipe, an adjusting assembly is further arranged in the first ball body, the supporting rod extends into the first ball to be connected with the adjusting assembly, a channel is formed in the supporting rod, one end of the channel communicates with the first ball, and the other end of the channel communicates with the arc-shaped concave face of the parabolic plate. A second telescopic pipe is further arranged in the first telescopic pipe, and the second telescopic pipe can stretch into the first ball body after expanding. By introducing gas into the first telescopic pipe and the second telescopic pipe, the height of the antenna can be adjusted, and impurities attached to the surface of the antenna can be cleaned, so that the antenna at a high position can be remotely maintained, and the situation that a maintainer falls off during high-position maintenance is avoided.

Description

technical field [0001] The invention relates to the technical field of ADS-B, in particular to an ADS-B signal transceiver. Background technique [0002] ADS-B technology is a new type of aircraft monitoring technology developed in recent years. It is an aircraft operation monitoring system based on GNSS satellite positioning and ground / air data link communication. Because its communication is not affected by climate and terrain, it can achieve all-weather real-time communication. . Compared with traditional radar surveillance technology, ADS-B technology has obvious advantages such as low cost of use, small precision error, high data update rate and strong surveillance capability. It also has broad application prospects for air traffic services in high-density flight areas, such as scene surveillance etc. Based on factors such as its low cost, easy installation and technological advancement, it has become an important technical means of current air traffic surveillance. ...

AI Technical Summary

Problems solved by technology

At present, in order to ensure that the ADS-B receiving equipment can effectively receive the transmitted signal, the antenna assembly of the ADS-B receiving equipment is usually installed at a high place, but after the antenna assembly is used for a long time, a large amount of dust will adhere to the surface, affecting The normal reception of the signal by the antenna and the bad weather will also have a certain impact on the ADS-B antenna components
