Abstract

The Traffic controller currently used in Korea is a switch control system that directly transfers 220V of high voltage to traffic lights one to one. This method requires a lot of cables, and there are concerns about electric shock. Accordingly, Korea Road Traffic Authority added the digital communication signal controller standard using digital communication method to the standard specification of the communication signal controller of the National Police Agency. Based on these specifications, this paper intended to develop digital communication call controllers. In addition, it was verified that even if the digital communication signal controller and analogue communication call controller were mixed, they could operate in the signal control system currently in operation.

현재 국내에서 사용되고 있는 교통신호제어기는 220V의 고전압을 신호등에 일대일로 직접 전달하는 스위치 제어 방식이다. 이러한 방식은 교통신호제어기와 신호등들을 연결하는 데 상대적으로 많은 케이블이 소요되고, 또한 감전에 대한 우려가 있다. 이에 따라 도로교통공단에서는 경찰청 교통신호제어기 표준규격서에 디지털 통신 방식을 이용한 디지털 교통신호제어기의 규격을 추가하였다. 본 연구에서는 이러한 표준규격서를 바탕으로 디지털 교통신호제어기를 개발하고자 하였다. 또한 디지털 교통신호제어기와 아날로그 교통신호제어기가 혼재되어 있어도 현재 운영 중인 신호제어시스템에서 운영이 가능함을 검증하였다.
