Snow melting or deicing system and snow melting or deicing method for satellite antenna

Abstract

The invention relates to a snow melting or deicing system and a snow melting or deicing method for a satellite antenna. The snow melting or deicing system comprises heaters, a rain or snow sensor, a controller, temperature sensors, a temperature acquisition box and a power supply module; a thermal insulation plate is arranged on the back of a reflection surface of the satellite antenna, and the thermal insulation plate and the back of the reflection surface of the satellite antenna form a closed space; the heaters are uniformly arranged in the closed space along the circumference of the satellite antenna, and the sector where each heater is located is a heating channel; the temperature sensors are arranged in the heating channels, and the rain or snow sensor is arranged at the edge of the main reflection surface of the satellite antenna; the heaters and the rain or snow sensor are all connected with the controller, the temperature sensors are connected with the temperature acquisition box, the temperature acquisition box is connected with the controller, and the power supply module supplies power to the controller. By adopting the intelligent control technology, once rain or snow is detected, the system runs automatically, and raining or snowing is ended, the system stops automatically. The system and the method have the characteristics of simple control, high efficiency, good snow melting effect and the like.

Description

technical field [0001] The invention belongs to the technical field of antennas, and in particular relates to a satellite antenna snow melting and deicing system and a snow melting and deicing method. Background technique [0002] The satellite antenna is an important equipment of the satellite ground station and a device for realizing energy conversion in the wireless communication system. It undertakes the task of transmitting and receiving electromagnetic waves. Most of the satellite communication systems work in the microwave frequency band (C, Ku, and Ka bands). Antennas used in high-latitude areas with high air humidity will encounter rain in late autumn and winter when the temperature is lower than 0°C or the humidity is high. In snowy weather, ice and snow will appear on the antenna reflector. This phenomenon will increase the load on the reflective surface of the antenna, and due to the uneven thickness of ice and snow, irregular irregularities often appear, and th...
