AWS-310A Automatic Weather Station（AWS）-Weather-Zhuhai Bright Aviation Inc.-Airport facilities and brand suppliers

一、Business

“Bright Aviation” supplies complete sets of equipment, including spare parts supply, installation and commissioning, technical consultation, after-sales service, spare parts support, equipment repair, factory training, software upgrade and other businesses.

二、Overview

1、“AWS” measure six conventional weather elements (wind direction, wind speed, temperature, humidity, air pressure, precipitation) around airport runways, providing high-precision and highly reliable real-time meteorological data to ensure the safety of airport flights and improve flight operation efficiency. It is one of the essential infrastructure in the modern aviation system.

2、“AWS”, also known as “Conventional Weather Observation Station”, “Conventional Weather Observation System”,“Conventional Automatic Weather Observation Station”.

3、The difference between “AWS” and “AWOS”:

(1)AWS is a simple Weather observation equipment that only provides system software and six element conventional Weather data.

(2) AWOS not only has all the functions of “AWS”, but also provides sensor data such as runway visual range, cloud height, and weather phenomena, and is equipped with powerful monitoring and automation software integration systems.

三、Characteristic

1. Monitor the data of six weather elements 24 hours a day.

2. When the real-time monitoring data exceeds the alarm threshold setting value, provide visual graphics and voice alarm prompts in a timely manner.

3. Perfect weather observation software, free system upgrade.

4. Communication mode: wired (optical cable or telephone cable) or wireless dual backup communication mode (optional).

5. Power supply mode: AC and DC power supply.

6. Stainless steel support and outdoor protection box are used. The box is solid, beautiful, corrosion resistant, waterproof and moisture-proof.

7. Continuous working for 24 hours, working stability ≥ 10 years.
