Specific embodiment

The utility model is described in detail with reference to the accompanying drawings and examples, attached drawing is used to explain together with embodiment Release the utility model, but it will be appreciated by those skilled in the art that, following embodiment is not to technical solutions of the utility model Unique restriction, all any equivalents or change done under technical solutions of the utility model Spirit Essence should all regard To belong to the protection scope of the utility model.

The utility model provides a kind of pacesetting system based on light tracking, and design concept is to be arranged one in roadside Bank light, the spacing between each lamp are fixed, and allow the sequence light on and off that lamp is regular, visually form a luminous point (or one group of light Point simultaneously) movement can calculate luminous point using the distance between adjacent two lamp (or two groups of lamps) and lamp bright time Movement speed.Induction by vision to this speed generates a kind of consciousness automatically tracked, keeps it as far as possible and the speed Unanimously.

Therefore, which includes a light bar 1 in trackside setting, and the light bar is by multi-lamp equidistantly along vehicle driving Direction is arranged to make up, and its spacing can be as needed from setting, as shown in Figure 1.

For the road of one-way trip, the light bar can all be arranged in the both sides of the road of an one-way trip, or only be existed Side arrangement；It is preferably placed in when side is arranged close to this side of driver, when two sides are arranged, two light bar are symmetrical flat Row setting.

For the road of two-way traffic, can also all be arranged (as one-way road) in two sides on each direction road, It can only be arranged on intermediate isolating band.When being arranged on intermediate isolating band, if twocouese will regulation speed, just in centre Opposite direction arranges two light bar 1,2 each other on isolation strip, and a row guides the vehicle in this direction, and another row guides another direction Vehicle.Further, to avoid interfering between two rows of lights, partition 3 can be set between two rows of lights band, or set on lamps and lanterns It sets and blocks 4, as shown in Figure 2,3.

Lamps and lanterns in light bar, to have the function of can regular automatic light on and off be spaced between each lamp in a bank light Identical distance, it is light to be also spaced the identical time between each lamp one by one, can be only achieved the effect of even speed stream, with two lamps The distance between L divided by interval time t light between two lamps, movement speed V, the V=L/t of the luminous point exactly shown, speed Degree V is exactly the induced velocity of regulation speed.In a bank light, the movement of luminous point is reciprocation cycle, forms a kind of light wave.One It in secondary circulation, is lighted one by one since first lamp, when next lamp is light, the lamp of front just goes out, remaining lamp is worked as It is so also to go out；One after circulation terminates, then carry out subsequent cycle is lighted since first lamp, thus constantly to the vehicle passed by It is guided.

Further, light bar will not only have the function of pacesetting, can also have the adjustable function of brightness, this Function is to avoid driver from leading to the case where diverting attention without noticing of light to meet different weather and light needs. So this technology can take LED light to realize these functions, not only can the automatic light on and off under controlled case, but also brightness is adjustable, Effect utmostly avoids influence of the extra color to driver obviously without dazzling.

Still further, lamps and lanterns take seat is vertical to be located at road side, height about arrives the vertical height of operator's seat, with driving Member's sight is substantially flush, and does not both have to take suspension type, without raising type is taken, without setting up high bar and high-altitude electricity Cable, electric wire can be taken buried, save many costs.

To realize above-mentioned each function, the utility model provides a kind of feasible circuit control system, as shown in Figure 4.At this In system, external AC220V power supply 101 is system power supply, and controller 103 is manipulated by 102 man-machine interface of host computer, had Controller need that alternating current is further become DC12~36V direct current by rectifier.Controllable resistor 104 is arranged in power supply Load --- on the circuit of lamp power supply, and the resistance value of controllable resistor 104 is controlled by controller 103, due to what is be added on circuit The resistance value of controllable resistor 104 is alterable, so the electric current on entire load supplying circuit is caused to change, the bright darkness of lamp is just It is adjustable.In the utility model, a bank light is set, as illustrated in the drawing a signal lamp 1051, two signal lamps in same light bar 1052 ..., until N signal lamp 105N, N are natural numbers, 105N indicates the natural order number to sort since 1051.Each lamp it Between be arranged in parallel, and be connected in parallel on by controllable resistor 104 adjust resistance value after circuit on, so its bright dark degree is consistent.

At the same time, a time-delay relay is all set on the parallel circuit of each lamp, and corresponding with lamp is No.1 1061, No. two time-delay relays 1062 ... of time-delay relay, until N time-delay relay 106N, same N is natural number, 106N indicates the natural order number to sort since 1061.Each time-delay relay is separately positioned on each parallel circuit, institute Can be controlled separately the light on and off of a lamp.

Each time-delay relay is all controlled by controller 103, thus can by the way that start-stop time of each time-delay relay is arranged, Realize the sequence light on and off of each lamp, and the light on and off of settable constant duration.Citing, if the No.1 time-delay relay 1061 in figure Closing time is 5 seconds, and No. two time-delay relays 1062 start after No.1 time-delay relay 1061 is closed 5 seconds, same with this When No.1 time-delay relay 1061 disconnect, No. two 1062 closing times of time-delay relay are also No. three delay relays after 5 seconds, 5 seconds Device 1063 starts, and No. two time-delay relays 1062 disconnect, and so goes down, is exactly to be spaced sequence light on and off in 5 seconds between each lamp.Pass through The light on and off time (the namely make-and-break time of control circuit) of time-delay relay control lamp；By controller 103 to it is each delay after Electric appliance setting is delayed the start-stop time at equal intervals, can make the identical time light on and off in each lamp interval, at regularity, in addition between each lamp Spacing is identical, is exactly the at the uniform velocity forward movement of bright spot from sense organ.

Function setting can be set by the man-machine interface of host computer 102, as shown in figure 5, setting starts, stops on host computer Only, the buttons such as brighten, be dimmed, further also settable gradually to brighten, is dimmed, gradually brightens, dimmed grade is available presses The number of button indicates, shows number on a display screen.Controller 103 goes the resistance of adjustment controllable resistor 104 according to light/dark grade Value.Controller 103 tap into end X0-X5 connection host computer 102, receive host computer 102 convey various instructions (as starting, stopping, Brighten, be dimmed, gradually brightening, is gradually dimmed), 1 controllable resistor 104 and 5 time-delay relay (one of output end Y0-Y5 connection Number, No. two, No. three, No. four, No. five time-delay relays 1061,1062,1063,1064,1065), the quantity of time-delay relay by Lamp number determines that a lamp matches a time-delay relay.

The distance between delay light on and off time and two lamps between two lamps determine the mobile speed of light (luminous point) Degree, can be by adjusting two lamp on/off times and/or apart from adjusting, in general, after lamp installs if speed is improper It will not move, so generally being adjusted by adjusting delay light on and off time of lamp.

It is easy to happen the section of traffic jam in uphill way, narrow road section and road section etc., it is settable a set of in roadside Induced velocity is set within the scope of standard speed limit by the pacesetting system of the utility model design according to vehicle traveling direction (standard speed limit is provided by traffic control department) will affect the sense organ of people, lower meaning as long as the light on and off speed of lamp is different from speed driver Know ground to be adjusted to speed and the mobile identical speed of light.It is tested by practical road surface, as a result indicates, pass through the shadow of light stream It rings, over-speed vehicles can be made to slow down the speed of 2-5km/h, make slow-moving vehicle speedup 2-13km/h.Due to using LED light, can increase Add night illumination brightness, solve local street lamp placement selection place hardly possible, the disadvantage of street lamp deficiency has the function of high beam, subtracts Few traffic accident caused by distance light light irradiation.Since light stream is directional and advance, bootable vehicle is by correct side To traveling, it is arranged in one-way road or highway, can effectively solves the problems, such as to drive in the wrong direction, reduce traffic accident.
