Abstract

본 발명은 초음파센서를 이용하여 교통량을 감지하고 그 교롱량의 흐름을 시간대별과 요일별로 누적 저장하여 두고서 이 누적 저장된 교통량 데이터를 기초로 신호등의 신호체계를 자동으르 제어하도록 하는 신호등 제어장치를 제공하기 위한 것이다.The present invention provides a traffic light control device that senses the traffic volume by using an ultrasonic sensor and accumulates and stores the flow of harassment by time and day, and automatically controls the signal system of the traffic light based on the accumulated stored traffic data. It is to.

이를 위해 본 발명은, 이동차량을 감지하는 초음파센서부(10)와, 상기 초음파센서부(10)에서 감지한 출력신호를 기초로 이동차량의 대수를 카운트하는 카운터부(20), 시간을 계시하는 타이머(40), 교통량데이터를 누적저장하기 위한 메모리 (50), 상기 카운터부(20)로부터의 카운트신호를 기초로 상기 타이머(40)의 시간에 따라 차량의 대수를 시간대별과 요일별로 계산하여 상기 메모리(50)에 저장하고 상기 메모리(50)에 저장된 교통량데이터를 기초로 신호등제어부(60)에 신호등 절환제어신호를 출력하는 마이컴(30)으로 이루어진 것을 특징으로 한다.To this end, the present invention, the ultrasonic sensor unit 10 for detecting the moving vehicle, the counter unit 20 for counting the number of the moving vehicle based on the output signal detected by the ultrasonic sensor unit 10, time The number of vehicles is calculated for each time zone and day of the week according to the time of the timer 40 based on a timer 40, a memory 50 for accumulating and storing traffic data, and a count signal from the counter unit 20. The microcomputer 30 stores the traffic light switching control signal to the traffic light control unit 60 based on the traffic data stored in the memory 50 and stored in the memory 50.
