The traffic light intelligent prompting control method is improved for the existing traffic light working mode, a brand new traffic light working mode is designed to synchronously provide vehicle drivers and passengers with the real-time working conditions of traffic lights ahead in the real-time driving directions of the vehicles and at the closes turnings, and the vehicle drivers and passengers are enabled to know the real-time working conditions of traffic lights ahead and at the turnings timely, and therefore, the defects of the existing running mode are overcome; in addition, in the process of providing the vehicle drivers and passengers with the real-time working conditions of the traffic lights at the turnings, information is transmitted by use of a broadcast signal in a one-way transmission manner so that the influence from any aspect on the work of the traffic lights can be thoroughly eliminated and normal and ordered road traffic can be guaranteed.
Description
Technical field
The present invention relates to
oneplant traffic lights intelligent prompt control method, belong to technical field of intelligent traffic.
Background technology
Traffic lights is often referred to and forms signal lamp for directing traffic by red, yellow, and green three kinds of color lamps, and during green light, permit vehicle pass-through, when amber light is bright, the vehicle having crossed stop line can continue to pass through; During when red, no thoroughfare for vehicles.Along with improving constantly of living standard, born of the same parents' amount of having of vehicle also increases increasingly, traffic network also becomes more crowded, more complicated, traffic lights thereupon for directing traffic also occurs to change, from initial simple light source, light source has been designed out direction finally, comprise craspedodrome, turn left, turn right and tune, and with the design also having countdown display occurred, be all while maintaining traffic order, give vehicle, pedestrian is more directly perceived, reliable signal lamp prompting, and in prior art, for the design of traffic lights, also run far deeper than these, such as number of patent application: 201010551590.9, disclose a kind of digitalization control method of traffic lights, each controlled traffic lights configures DTU unit, DTU unit connection signal amplifying circuit is connected with traffic lights with after driving circuit, each DTU unit has unique address code, the DTU unit had with this particular address code corresponding address code is transferred to by wireless-transmission network by intracardiac in the controlling for the control signal being loaded with steering order " 0 " or " 1 " and particular address code, DTU unit receives control signal, controls traffic lights work after control signal being amplified by driving circuit according to steering order.Technique scheme can control every traffic lights separately, overcomes the restriction of crossing traffic lamp interlocking, is convenient to control traffic lights according to actual traffic situation neatly.
Also has number of patent application: 201210534238.3, disclose a kind of emergent radio remote control traffic light apparatus, for controlling the telepilot of traffic lights, institute's telepilot is built-in with single-chip microcomputer, described single-chip microcomputer is connected with wireless transmitter module, described traffic lights is provided with single-chip microcomputer, described single-chip microcomputer is connected with wireless receiving module, the wireless receiving module installed on traffic lights given by described telepilot by wireless transmitter module emission instruction signal, the single-chip microcomputer that the information received passes on traffic lights processes by wireless receiving module, thus control the transit time of traffic lights display, and transit time is presented on light-emitting diode display.The emergent radio remote control traffic light apparatus of technique scheme design can make traffic police's manual remote pilot traffic lights traffic lights after the traffic conditions at the crossing observed obtain length to occur to the situation reducing traffic jam, and this device can reduce again the difficulty that traffic police dredges traffic facilitating everybody to go on a journey to reduce while traffic congestion.
Moreover, the patent No.: 201210136746.6, disclose the traffic lights fault supervisory systems of a kind of sing on web GIS, this system is primarily of traffic lights information acquisition terminal, supervision center, supervisory user end, maintenance user side composition, realized the two-way communication of information by mobile communications network and Internet network between them, traffic lights information acquisition terminal periodically gathers the status information of traffic lights and the failure message of appearance is sent to supervision center with note form, supervision center is analyzed failure message, process, traffic lights real time fail information is provided to the supervisory user end logged in by browser with the form of WebGIS map, and the appointment optimization that supervision center automatically can carry out maintenance task after receiving new failure message calculates and send maintenance task instruction from trend maintenance user side after monitor staff confirms, system achieves real-time monitoring to traffic lights and on-call maintenance, adds the time between failures of traffic lights, thus ensures the safety of road traffic and unimpeded.
Make a general survey of the Design of Traffic Lights of prior art, can find out that deviser is that the development of traffic lights provides many improvement, design proposal, but in the driving of reality, still can there are some problems in traffic lights, such as a dolly follows a cart to pass behind crossing, dolly is followed after cart, just be difficult to observe, even directly do not observe the situation of crossing traffic lamp, likely cart passes through stop line in the very last seconds of green light, when dolly is again by stop line, the situation of just likely making a dash across the red light, Here it is cart blocks for dolly the trouble that sight line causes, mention traffic, regardless of size, the traveling of vehicle is related to the safety of driver and crew and vehicle periphery people, the current mode that sight line is blocked at this crossing brings puzzlement to countless driver, therefore, this is the deficiency also existed in existing traffic lights.
Summary of the invention
