CN203102602U - A road sign that shows traffic flow - Google Patents

Abstract

The utility model discloses a signpost capable of displaying a traffic flow, belonging to the field of traffic signposts. The signpost comprises a main signpost body (1) and a controller (2), wherein a plurality of road signs (7) are printed on the main signpost body (1); the road signs (7) are provided with red LED (Light Emitting Diode) lamp bands (4), yellow LED lamp bands (5) and green LED lamp bands (6); and the controller (2) comprises an MCU (Microprogrammed Control Unit) control circuit, an LED driving circuit, a power supply circuit and a GSM (Global System For Mobile Communication) module. The traffic flow information of a nearby road is acquired through the communication between the GSM module and a remote computer, and the traffic flow situation of each road is reflected through the LED lamp bands with different colors, so that a driver can avoid a traffic jamming road section in time and select other smooth road sections to drive, and furthermore, the road traffic load is relieved.

Description

A road sign that shows traffic flow

technical field

The utility model relates to a road signboard capable of displaying traffic flow, which belongs to the field of traffic signboards.

Background technique

Road congestion in big cities has become a headache for people, especially during the peak hours of commuting. Traffic jams are very serious. When you find a traffic jam after driving into a road, it is difficult to change the road and you can only wait for the road helplessly. unimpeded. Nowadays, with the improvement of science and technology, there is already a traffic flow detection device, and the traffic management department can obtain the traffic flow of each road through this device, but ordinary drivers need to know the flow information of some roads through traffic radio stations. , neither comprehensive nor timely.

Utility model content

The utility model provides a road indicator board capable of displaying traffic flow, and the indicator board can indicate the traffic flow information of nearby road sections to drivers.

The utility model adopts the following technical solutions for solving the above technical problems:

A road sign capable of displaying traffic flow, comprising a main body of the sign and a controller; several road signs are printed on the main body of the sign; red LED strips, yellow LED strips and green LED strips are arranged on the road signs. LED light strip; the controller includes an MCU control circuit, an LED drive circuit, a power supply circuit and a GSM module; the MCU control circuit is respectively connected to the red LED light strip, the yellow LED light strip and the green LED light strip through the LED drive circuit; The MCU control circuit is connected with the GSM module through a serial port data line.

As a further optimization solution of the utility model, it also includes an LED subtitle screen; the LED subtitle screen is located below the main body of the sign; the MCU control circuit is connected to the LED subtitle screen through an RS485 communication line.

The utility model adopts the above technical scheme, and has the following technical effects compared with the prior art:

The utility model obtains the traffic flow information of nearby roads through the GSM module, and intuitively reflects the traffic flow conditions of these roads through the LED light strips of three different colors, which is convenient for drivers to choose smooth roads for driving.

The utility model has an LED subtitle screen, and the subtitle screen can be used to play some bad weather attention information to remind drivers to drive carefully.

The MCU control circuit controls the LED subtitle screen to display subtitles through RS485 communication, which has the characteristics of strong dry resistance.
