Abstract
The invention relates to an intelligent traffic light, in particular to an intelligent traffic light based on AT89S51. The invention provides an intelligent traffic light which is more efficient and more flexible. The intelligent traffic light comprises an AT89S51 singlechip, detection devices, a switch device and a time display device, and is characterized in that: the intelligent traffic light is provided with the detection devices respectively in the east-west direction and in the south-north direction, a car flow signal is transmitted to the singlechip to be processed, and the singlechip controls the traffic light time and the time display device in real time according to the car flow.
Description
Technical field:
The present invention relates to a kind of intelligent traffic light, more particularly, relate to a kind of intelligent traffic light design based on AT89S51.
Background technology:
At present, domestic traffic lights generally is located at the four crossway door, at the pilot lamp of full position with red, green, yellow three kinds of colors.The demonstration timer that adds a countdown is controlled driving.For safe driving generally speaking; Vehicle shunting still can play a role, but according to situation about occurring in the actual driving process, also has following shortcoming: 1. to banish line time identical for the vehicle wheel in liang track; At the parting of the ways; Often a track is major trunk roads, and vehicle is more, and the clearance time should be grown; Another track is an auxiliary main road, and vehicle is less, and the clearance time should lack.2. the red green time of two arterial highways can not be in time and the variation of vehicle flowrate and changing.
Summary of the invention:
The present invention is exactly to the problems referred to above, and a kind of intelligent traffic light more effectively more flexibly is provided.
For realizing above-mentioned purpose; The present invention adopts following technical scheme; The present invention includes AT89S51 single-chip microcomputer, pick-up unit, switchgear, time display; Its structural feature respectively is provided with pick-up unit at thing and North and South direction, and gives single-chip microcomputer the vehicle flowrate signal and handle, and single-chip microcomputer is according to vehicle flowrate controlled in real-time traffic lights time and time display.
Beneficial effect of the present invention:
Because the present invention detects in real time and controls condition of road surface, just can regulate transit time automatically according to the size of each road cross vehicle flowrate, reach the purpose of optimizing traffic.
Description of drawings:
Fig. 1 is a structure principle chart of the present invention.
Embodiment:
The present invention includes AT89S51 single-chip microcomputer, pick-up unit, switchgear, time display; Respectively be provided with pick-up unit at thing and North and South direction; And give single-chip microcomputer the vehicle flowrate signal and handle, single-chip microcomputer is according to vehicle flowrate controlled in real-time traffic lights time and time display.
Embodiment 1
When pressing urgent key, four direction all is a red light, and charactron stops timing.(benefit of this function is when severe traffic accidents takes place in the crossroad, can pass through button, makes traffic lights red entirely, can let the more efficient processing accident of traffic police like this, can not let traffic that serious obstruction is arranged.)
When pressing cancel key, traffic lights is got back to original countdown operate as normal.
Embodiment 2:
When some direction vehicles are crowded will cause the traffic congestion phenomenon time, pick-up unit will in time send the single-chip microcomputer that signal is given control module, according to the green time of suitable this direction of increase of setting value, increase the red time of another direction simultaneously; Give time display with the new demonstration time simultaneously.
Claims (3)
1. intelligent traffic light; Comprise AT89S51 single-chip microcomputer, pick-up unit, switchgear, time display; It is characterized in that respectively being provided with pick-up unit at thing and North and South direction; And give single-chip microcomputer the vehicle flowrate signal and handle, single-chip microcomputer is according to vehicle flowrate controlled in real-time traffic lights time and time display.
2. a kind of intelligent traffic light according to claim 1 is characterized in that described switchgear when pressing urgent key, and four direction all is a red light, and charactron stops timing.
3. a kind of intelligent traffic light according to claim 1; It is characterized in that described pick-up unit is when some direction vehicles are crowded will cause the traffic congestion phenomenon time; Pick-up unit will in time send the single-chip microcomputer that signal is given control module; According to the green time of suitable this direction of increase of setting value, increase the red time of another direction simultaneously; Give time display with the new demonstration time simultaneously.
