Description

A transformable road yellow solid line system

technical field

The utility model relates to a road traffic device, in particular to a convertible road yellow solid line system.

Background technique

With the rapid development of my country's economy, the road status of many cities can no longer meet the needs of traffic, which seriously limits the steady development of cities. Take Nanjing as an example. Since the 21st century, the rapid development of Nanjing city has attracted a large number of foreign technical personnel. Due to economic and other reasons, foreign technical personnel basically choose to live in Jiangbei, and most of the companies they work for are located in the main urban area. This has resulted in the Nanjing Yangtze River Bridge's morning peak traffic flow direction being from the bridge north to the main urban area, and evening peak traffic flow direction from the main urban area to the bridge north. Therefore, the traffic congestion in one direction is serious, while the traffic flow in the other direction is too small, and the lane utilization rate is not high. Vehicles scratching in the same direction and rear-end collision accidents occur frequently, seriously affecting people's travel. Therefore, it is particularly important to monitor the traffic flow information in all directions in real time, adjust the yellow solid line of the road in time, make full use of each lane, and ensure that the traffic on the bridge deck is carried out in an orderly manner.

At present, the main way to replace the yellow solid line on the bridge deck with manual measures is: the traffic control department estimates the traffic volume in each direction, manually arranges fences, cone-shaped barrels, or a traffic policeman at a certain distance to direct the traffic. This method has a large workload and low efficiency, and cannot efficiently guide traffic.

Utility model content

The purpose of the utility model is to overcome the shortcomings in the above-mentioned prior art, and provide a system for changing the yellow solid line of the road.

In order to achieve the above object, the utility model adopts the following technical solutions:

It includes the chassis and the single-chip microcomputer installed in the chassis. The input terminals of the single-chip microcomputer are respectively connected with the speedometers used to measure the speed of vehicles in all directions, and the output terminals of the single-chip microcomputer are connected with strip fluorescent lamps. line position.

The lane is located on the bridge deck.

The strip-shaped fluorescent lamp adopts a light-emitting side cover plate of white light-transmitting material.

Described single-chip microcomputer is MSP430 single-chip microcomputer.

The speedometer is HT3000 flat-panel narrow-wave radar speedometer.

The strip fluorescent lamps are arranged in two rows at the same lane boundary and lane centerline, and the total width of the two rows of strip fluorescent lamps is the same as the width of the corresponding lane boundary or lane centerline.

The utility model has the following beneficial effects: the utility model uses a speedometer to obtain real-time traffic conditions of vehicles in all directions on the road, and then changes the position of the center line of the lane by lighting up the strip fluorescent lamps at the corresponding positions, thereby accurately dividing the vehicles in each direction. The driving lane has the advantages of simple structure and rapid division of lanes, which improves the efficiency of traffic control.

Detailed ways

Below in conjunction with accompanying drawing and embodiment the utility model is described in detail.

Referring to Fig. 1 and Fig. 2, the variable road yellow solid line system described in the utility model comprises cabinet 2 and the single-chip microcomputer that is arranged in the chassis 2, and described single-chip microcomputer is MSP430 single-chip microcomputer, and the input end of single-chip microcomputer is used for measuring each direction vehicle speed respectively. The speedometer 1 is connected, the speedometer is HT3000 flat narrow-band radar speedometer, the output end of the single-chip microcomputer is connected with the white strip-shaped thin-plate fluorescent lamp 5, and the light-emitting side cover plate of the white light-transmitting material is used for the fluorescent lamp, which is not lit. It is white at the time, and emits yellow light after being lit. The fluorescent lamp is set on the lane boundary line (white, used to separate traffic flow in the same direction) on the bridge surface and the center line of the lane (yellow, used to separate traffic flow in the opposite direction). traffic flow), the fluorescent lamps are arranged in two rows at the same lane boundary position and lane centerline position, and the total width of the two rows of fluorescent lamps is the same as the width of the corresponding lane boundary line or lane centerline, and can be flashed in a single row Or the single column lights up first to inform the vehicle that the traffic lane is about to change.

Working principle of the utility model:

Before use, refer to Fig. 1 to carry out equipment connection, the input end of the MSP430 single-chip microcomputer in the chassis 2 is respectively connected to the HT3000 flat narrow-wave radar speedometer 1 for measuring the speed of each direction; Fluorescent lamps 5, the device may be powered by rechargeable batteries.

Referring to Fig. 2 and Fig. 3, when the vehicles in each direction enter the bridge head, the speedometer measures N groups of vehicle speed values in each direction, and transmits them to the chassis 2, and the single-chip microcomputer processes the incoming data to calculate the vehicle speed in each direction. Average V ₁ , V ₂ , and make a difference M=V ₁ -V ₂ , and make a judgment: when M≥0 or when M<0, if the absolute value of M is larger, it means that the traffic congestion is more serious, so More lanes should be allocated to the traffic flow in this direction. According to the judgment results, it is determined that one of the white strip-shaped thin-plate fluorescent lights at the position of the lane boundary line from 1 to 2K+1 is yellow, so as to achieve the effect of separating the opposite lanes and make the center line of the lane position to move to the other lane.

In this patent application, the single-chip microcomputer divides several threshold ranges (m ₁ ,...,m _a-1 ,...,m _a in Figure 3) and performs corresponding operations within the corresponding threshold ranges. You can refer to the document "The Temperature Based on the MSP430 Single-chip Microcomputer and Gas Alarm System Design_Zhao Na".

In a word, the utility model imports the speed information of the traffic flow in each direction into the single-chip microcomputer in the chassis through two speedometers, and turns on the corresponding fluorescent lamp through the control of the single-chip microcomputer, so that it is transformed into a yellow solid line. So as to accurately and quickly divide the traffic lanes in each direction. At the same time, by arranging a display unit and a key input unit connected to the single-chip microcomputer in the chassis, it is also possible to manually divide the traffic lanes in each direction according to the speed information of the traffic flow in each direction.
