Abstract

The 3D ultrasonic anemometer transmits measured data by connecting PC and RS232C interface. Depending on the observation location, it is often necessary to extend the cable connecting the PC and the sensor. When installing on the test bed of the Air Meteorological Agency, the original AWM2919 cable was required to be extended because the distance between the PC container and the equipment installation site was more than 30 m. The cable was extended through a process such as extending the AWM2919 cable, converting the interface with the PC from RS232C to RS485, and testing the RS485 communication. After the equipment was installed with an extended cable, data were remotely collected and analyzed to confirm successful cable extension.

3차원 초음파풍속계는 PC와 RS232C(:Recommended Standard 232C) 인터페이스로 연결하여 관측 자료를 전송한다. 관측 장소에 따라 PC와 센서를 연결하는 케이블 연장이 필요한 경우가 종종 발생한다. 항공기상청 항공기상관측장비 테스트베드에서 PC를 두는 콘테이너와 장비 설치하는 곳까지 거리가 30 m 이상 되어 본래의 AWM2919(:Appliance Wiring Material 2919) 케이블로의 연장이 필요했다. 문제 해결을 위해서 AWM2919 케이블 연장, PC와의 인터페이스를 RS232C에서 RS485로 개조, RS485 검사 등의 조치를 하였다. 연장된 케이블로 장비를 설치한 후에 원격으로 자료를 수집하고 분석하여 성공적인 케이블 연장을 확인하였다.
