Title:
TRAFFIC SIGNAL LIGHT SYSTEM
Document Type and Number:
WIPO Patent Application WO/2017/177912
Kind Code:
A1
Abstract:
A traffic signal light system comprises a signal machine (1610), a main controller (1630), and a road surface type bidirectional traffic signal light (1620, 600). The signal machine (1610) is in communication connection with the main controller (1630). A control signal output interface of the main controller (1630) is connected to a control signal input interface of the road surface type bidirectional traffic signal light (1620, 600). The road surface type bidirectional traffic signal light (1620, 600) comprises a main housing (60), a main control circuit board, a first light-emitting device (611), a second light-emitting device (621), a first protective cover (612), and a second protective cover (622). A third accommodating chamber used for accommodating the main control circuit board is disposed on the main housing (60). A first accommodating chamber (613) used for accommodating the first light-emitting device (611) is disposed on a first side surface of the main housing (60), and a second accommodating chamber (623) used for accommodating the second light-emitting device (621) is also disposed on a second side surface of the main housing (60). The first light-emitting device (611) and the second light-emitting device (621) are independently controlled by the main control circuit board. The system helps to improve the vehicle passing efficiency and the safety controllability of a planar intersection.
