Embodiment

[0029] Example: such as figure 1 As shown, the present embodiment relates to a composite function light warning guidance system for urban underground roads. The system includes

[0030] A control module, the control module stores all the spatial information of the underground road, can receive the accident information of the underground road, and can issue control instructions for the light-emitting module and the rotatable light-reflecting device;

[0031] A rotatable reflective device, the rotatable reflective device is composed of a wireless Internet of Things module, a control circuit, an electric rotary rod 6 and a reflector 7, the wireless Internet of Things module can wirelessly receive instructions from the control module, and the instructions are controlled by the control circuit Rotate the pole so that the reflective device is retracted or put down.

[0032] A light-emitting module, the light-emitting module is composed of a wireless Internet of Things module, a co...

Abstract

The invention particularly relates to a composite function light warning and guiding system for urban underground roads. A control module stores all space information of the underground roads, can receive underground road accident information and can release control instructions for a light emitting module and a rotary reflection device. The light emitting module is composed of a wireless internet-of-things module, a control circuit and a lamp set containing a plurality of LED lamp beads, and the instructions from the control module can be wirelessly received, so that the light color and the flickering frequency are changed. The system can form geometric light beams on underground road top plates and side walls, so that the contours of the underground roads are effectively marked, and a strong vehicle speed feeling is provided for drivers in the underground roads. For traffic accident road sections of the underground roads, a light mode can be switched to timely warn subsequent vehicles for deceleration and avoidance. For division and confluence portions of the underground roads, division of front entrances and exits can be effectively forecasted, and the vehicles are guided to drive into the underground roads in time.

Description

technical field [0001] The invention relates to aspects of underground road accident warning and early warning and traffic guidance, in particular to a composite function light warning and guidance system for urban underground roads. Background technique [0002] As a relatively closed structure, underground roads face problems such as insufficient lighting conditions, poor lighting conditions in the driving environment, and few reference objects. [0003] The underground road is a weak visual reference system. When the vehicle is driving at high speed in the underground road, due to low illumination, few reference objects, low contrast, and monotonous environment, the driver will have visual illusions and misjudgment of speed, distance, and time. [0004] Driving in a monotonous visual environment for a long time will cause visual fatigue and inattention to the driver, which will easily lead to bad driving behavior, causing traffic accidents such as hitting the side wall of...
