Problems solved by technology

[0003] There are also induction coils buried underground in all directions near the intersection. When a car passes by, eddy current loss will occur, and the inductance of the ring-shaped insulated wire will begin to decrease, and the passing of the car can be detected, but the volume of the induction coil is about 2 meters × 2 meters, inconvenient to install and easy to be crushed and difficult to be widely used

Embodiment Construction

[0020] The distribution diagram of traffic flow direction at the intersection of the road traffic signal light control system based on GSM network is as follows figure 1 As shown, the traffic flow distribution diagram at the intersection only shows one of various types of traffic flow distribution and its traffic control. The GSM network-based road traffic signal light control system for other types of vehicle flow distribution and its traffic control can be easily obtained by analogy. get. figure 1 In the middle, when the red light is on in the east-west direction, in the north-south direction, A is the time when the green light is on for the straight-through and right turn, and B is the time for the green light for the left turn to be on

[0021] The schematic diagram of embedding the laser diode is as follows figure 2 shown. Its structure includes: steel pipe (1), cover plate (2), round glass sheet (3), laser diode kit (4), fixing plate (5), screw kit (6), bracket (7), j...

Abstract

The invention relates to a road traffic signal light control system based on a GSM network. A laser correlation apparatus which is installed on each lane outflux of a crossroad measures the number of vehicles which pass through the lane outflux at green light. According to traffic data of the front crossroad, release time is calculated, simultaneously a distance between the vehicles during the release time is measured and a release traffic congestion condition is determined. The strong GSM network is used and communication among the crossroads is realized through a mode of sending short messages to each other.

Description

(1) Technical field: [0001] The invention relates to a road traffic signal light control system based on a GSM network. It measures the number of vehicles passing through the exits of the lanes by means of a laser beam-shooting device installed at the exits of each lane at the intersection, and calculates the release time based on the traffic data at the crossroads ahead. At the same time, measure the distance between the front and rear vehicles when passing, judge the congestion situation of the passing vehicles, and use the powerful GSM network to realize the communication between the intersections by sending text messages to each other. (two) background technology: [0002] With the rapid development of my country's economy, the number of urban motor vehicles and the total traffic volume continue to increase, and the corresponding road infrastructure construction is difficult to keep up with in time. capacity bottleneck. Especially during commuting hours, the traffic is v...
