Assistant system of pedestrian safety of intersection

Abstract

The invention relates to an assistant system of pedestrian safety of an intersection, which is characterized by comprising a laser barrier module, a pedestrian monitoring prewarning module and a vehicle and road communication control module; the laser barrier module comprises two light source emitting props arranged in one diagonal position of both ends of a pedestrian crossing and two light source receiving props arranged in the other diagonal position of both ends of the pedestrian crossing; more than one group of laser light sources are correspondingly arranged on the two light source emitting props at intervals; each group of laser light source comprises two laser light sources arranged on each light source emitting prop; the pedestrian monitoring prewarning module comprises two voice warning devices and a photosensitive detecting device which corresponds to each laser light source; the vehicle and road communication control module comprises a singlechip control system, a communication interface and a corresponding peripheral circuit; the singlechip control system is electrically connected with each module respectively; the singlechip control system is used for obtaining state signals of red, green and yellow lights and sending signals for controlling opening or closing of the laser light sources; and when a pedestrian runs the red light, the singlechip control system sends a signal to the pedestrian monitoring prewarning module for warning the pedestrian. The system provided by the invention is widely applied for city traffic.

Description

technical field [0001] The invention relates to a safety auxiliary system, in particular to a safety auxiliary system for pedestrians at crossroads using a laser light source to simulate a fence based on a single-chip microcomputer control system. Background technique [0002] At intersections with heavy urban traffic, pedestrians frequently run red lights, which not only poses a huge threat to the personal safety of pedestrians, but also disrupts traffic order and affects the smooth running of the entire intersection, which will inevitably lead to a reduction in traffic efficiency. [0003] In the prior art, some measures are taken to avoid the occurrence of this situation as much as possible, such as arranging traffic coordinators on road sections with large traffic volumes to directly command vehicles and pedestrians.

[0002] At intersections with busy urban traffic, pedestrians run red lights frequently, which not only poses a huge threat to the personal safety of pedestrians, but also disrupts traffic order and affects the smooth running of the entire intersection, which will inevitably lead to a reduction in traffic efficiency.

[0003] In the prior art, some measures are taken to avoid the occurrence of this situation as much as possible, such as arranging traffic coordinators on road sections with large traffic volumes to directly command vehicles and pedestrians. This method can effectively reduce the situation of pedestrians running red lights, but it needs Invest a lot of manpower and material resources; another example is to install railings at both ends of crosswalks at intersections. The railings can be opened or closed at any time according to the red, green, and yellow light signals. This method can reduce pedestrians running red lights to a certain extent, but physical railings take up space Larger, timed opening and closing of railings and safety hazards of railings will reduce the efficiency of traffic
