Abstract

본 발명은 횡단보도의 교통신호 제어 방법 및 장치에 관한 것으로, 종래에는 주 제어기의 중첩 운용에 사용될 수 있는 여분의 출력이 제한적이어서 다수의 이격 횡단보도에 대해 중첩 운용이 필요함에도 불구하고 중첩 운용을 지원할 수 없고 또한, 중첩 운용을 위해 여러 가닥의 등기 선로를 통상 수백 미터 가설하여야 하는 불편과 도시 미관에 악영향을 초래하는 문제점이 있었다. 이러한 문제점을 개선하기 위하여 본 발명은 독립 횡단보도에 분산 제어 모듈인 신호 제어기를 설치하고 주 제어기와의 통신을 통해 해당 횡단보도의 신호등을 제어하도록 창안한 것으로, 본 발명은 이격 횡단보도에 설치된 분산 제어기와 주 제어기간 제어 지령 및 제어결과를 교환하도록 공중 통신망을 적용하여 이격 횡단보도의 신호등을 제어함으로써 모든 이격 횡단보도에 신호등을 설치, 운용할 수 있고 또한, 독립 횡단보도에 설치되는 분산 제어기의 구성이 교통 신호 제어기에 비하여 극히 간단하고 제작 단가도 낮으므로 많은 이격 횡단보도에 신호등을 설치할 수 있다.The present invention relates to a traffic signal control method and apparatus for pedestrian crossings. In the related art, a redundant output that can be used for the overlapping operation of the main controller is limited, so that the overlapping operation is required despite the overlapping operation for a plurality of spaced crosswalks. There was a problem that it could not support and also caused inconvenience to the city aesthetics and inconvenience of having to lay several hundred meter tracks for overlapping operation. In order to solve this problem, the present invention is to provide a signal controller which is a distributed control module in an independent pedestrian crossing and to control the traffic light of the corresponding crosswalk through communication with the main controller, the present invention is distributed in a spaced crosswalk By applying the public communication network to exchange the control command and control result with the controller, the traffic lights can be installed and operated at all the crosswalks by controlling the traffic lights of the spaced crosswalks. The construction is extremely simple compared to the traffic signal controller and the manufacturing cost is low, so it is possible to install the traffic light in many pedestrian crossings.
