A kind of intelligent transportation system
Technical field
The utility model belongs to automatic detection field, is specifically related to a kind of intelligent transportation system.
Background technology
Traffic hazard becomes " the first in the world evil ", and China is one of country that toll on traffic is maximum in the world.From later 1980s Chinese transportation accident year death toll exceed first 50,000 people so far, approximately 500,000 of the annual traffic hazards of China, because toll on traffic exceedes 100,000 people every year, rank first in the world for continuous more than ten years.
The generation of traffic hazard is much because make a dash across the red light, the pedestrian and non motorized vehicle phenomenon of making a dash across the red light occurs again and again, bring huge hidden danger to traffic safety, nowadays often in peak period, can set up traffic police at crossing and carry out control, but manpower is limited after all, basic pipe is not come, moreover in most of situation, all there is no traffic police, make a dash across the red light and bring significant damage to traffic safety.
Summary of the invention
The utility model provides a kind of intelligent transportation system, the utility model intelligent transportation system, be provided with infrared sensor, this infrared sensor is arranged on the pedestrian Accreditation Waiting Area of zebra stripes, if pedestrian running red light, can monitor and transmit information to single-chip microcomputer, single-chip microcomputer is processed rear control buzzer warning to data-signal, reminds pedestrian not make a dash across the red light; The utility model intelligent transportation system, is provided with traffic lights module, and this traffic lights module, in the time of when red, is sent signal to single-chip microcomputer, and Single-chip Controlling infrared sensor starts monitoring, and in the time of green light, Single-chip Controlling infrared sensor cuts out monitoring; The utility model intelligent transportation system, has effectively prevented the behavior of pedestrian running red light, and in the zebra money both sides at each crossing, pedestrian's traffic lights arrange.
Technical solutions of the utility model are as follows:
A kind of intelligent transportation system, is characterized in that, comprises microprocessor module, infrared sensor module, alarm module and traffic lights module; Described infrared sensor module, alarm module and traffic lights module are all connected with microprocessor module.
Described microprocessor module adopts AT89S51 single-chip microcomputer.
