Description
Technical field
The utility model relates to a kind of intersection multilane vehicle, the personnel traffic signals display device of current management in order, intelligent traffic signal pilot lamp that particularly a kind of embedded countdown shows of being used for.
Background technology
At present, the intelligent traffic signal pilot lamp in that the intersection of road is provided with generally becomes the traffic signals pilot lamp by red, green, yellow tri-colour LED with a countdown display group.Because the countdown display is again the separate component that separates with red, green, yellow tri-colour LED, so there are many problems in actual use: the one, increased material and installation cost.Because the countdown display is independent the setting, just need to increase corresponding components and parts and connecting line and the shell installed, increase the workload and the expense of installing; The 2nd, reliability reduces.Because device is many more, tie point is many more, complicated more, reliability is inevitable just low more; The 3rd, because the countdown display has only one, therefore, when there was a plurality of track at a crossing, the countdown display just can't show simultaneously.Such as, when left-hand rotation and craspedodrome all were green light, the time of its countdown was different, and the countdown display just can't show simultaneously; The 4th, the luminosity of pilot lamp and display can not be controlled.No matter day and night, signal lamp and countdown display all are operated in high brightness, current state, have quickened device aging, have reduced the serviceable life of traffic signals pilot lamp and countdown display; The 5th, versatility is poor.Present countdown display is to be produced separately by different producers, supporting use is provided for the traffic lights of oneself producing, and unified standard does not cause the countdown display of different manufacturers incompatible.This just gives maintenance, changes and brought trouble, has increased the cost of maintenance, replacing.
Summary of the invention
The purpose of this utility model provide a kind of that countdown display and red green or yellow tri-colour LED are united two into one, have an intelligent traffic signal pilot lamp that reliability height, highly versatile, display brightness can self-regulating embedded countdown show.
Its technical scheme is: the intelligent traffic signal pilot lamp that a kind of embedded countdown shows, form by traffic signals pilot lamp controller, single-chip microcomputer, light sensor, constant-current drive circuit, LED installing plate and power supply, it is characterized in that: on the described LED installing plate according to the form of disk frame or arrow frame, dot matrix is installed disc or the sagittate pilot lamp display part that is made of light emitting diode on its frame line, and dot matrix is installed the countdown display part of the digital or progress bar formula that is made of light emitting diode in its frame line; The power supply of the light emitting diode of pilot lamp display part and countdown display part is supplied with by monolithic processor controlled constant-current drive circuit respectively; The input end of single-chip microcomputer is connected with light sensor.
Its technique effect is: owing to the formation pilot lamp display part and the light emitting diode that constitutes the countdown display part with the traffic signals pilot lamp, be installed on the same LED installing plate, and adopt single-chip microcomputer to constituting the power supply of pilot lamp display part and the light emitting diode that constitutes the countdown display part, control respectively, characteristics such as therefore, the intelligent traffic signal pilot lamp of this embedded countdown demonstration has multi-functional demonstration, reliability height, highly versatile, cost is low, installation and maintenance are convenient; Simultaneously, the input end of single-chip microcomputer is connected to light sensor, can regulate the LED luminous intensity automatically according to ambient brightness, has both saved the energy, has prolonged the serviceable life of LED again.
