Abstract
Piggybacking left-hand rotation Dynamic Signal lamp, comprise control chip, control chip connects power supply, clock circuit and system change-over circuit respectively, described system change-over circuit connects multichannel latch cicuit, described latch cicuit connects a LED drive circuit respectively, LED drive circuit connects the LED group in left-hand rotation display screen respectively, and described latch cicuit is also connected in parallel a relay, and the control end of relay connects wireless controller.Control chip in the utility model alternately can export control signal, makes the lamp group roll display in left-hand rotation display screen, improves the notice of driver, ensure that the traffic efficiency of road.
Description
Technical field
The utility model relates to urban road junction field of traffic control, especially relate to a kind of can the piggybacking left-hand rotation Dynamic Signal lamp of Dynamic Announce.
Background technology
Crossing is as the key node in urban traffic network, and its smoothness, security have vital effect to city road network trouble-free operation.Turning to of wagon flow and the behavior such as conflict, intersection, shunting, interflow between the various wagon flows caused make the traffic characteristics more complicated of crossing, and crossing often becomes the key point whether urban transportation passes unimpeded.Crossing left turn traffic is the principal element producing conflict point, and irrational left turn traffic tissue can make intersection efficiency decline, and the delay time at stop is long, and vehicle queue causes obstruction to traffic, and toxic emission aggravates.Therefore, no matter be the capacity and level-of-service improving crossing, or ensure traffic safety, reduce motor vehicle exhaust emission, the science organization of left turn traffic is all most important.During existing intersection accidents tissue and signal control, in order to ensure the current smoothly of left turn traffic, the means usually adopted have: arrange exclusive left-turn lane, increase left turning vehicle transit time etc.The crossing more for left turning vehicle or intersection traffic pressure is larger, the exclusive left-turn lane arranged by broadening often can not meet current demand.Existing piggybacking left-hand rotation signal light path, belong to static state display, driver easily ignores, and causes the reduction of road efficiency.
Utility model content
In order to overcome above-mentioned technical matters, the utility model provide a kind of can the piggybacking left-hand rotation Dynamic Signal lamp of Dynamic Announce, the technical scheme of employing is as follows:
Piggybacking left-hand rotation Dynamic Signal lamp, comprise control chip, control chip connects power supply, clock circuit and system change-over circuit respectively, described system change-over circuit connects multichannel latch cicuit, described latch cicuit connects a LED drive circuit respectively, LED drive circuit connects the LED group in left-hand rotation display screen respectively, and described latch cicuit is also connected in parallel a relay, and the control end of relay connects wireless controller.
Further, described control chip adopts CD40193 chip.
Further, described clock circuit adopts CD4001 chip or crystal oscillating circuit.
Further, described LED group adopts red and green color LED.
Adopt above-mentioned piggybacking left-hand rotation Dynamic Signal lamp, control chip alternately can export control signal, makes the lamp group roll display in left-hand rotation display screen, improves the notice of driver, ensure that the traffic efficiency of road.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of piggybacking left-hand rotation Dynamic Signal lamp.
Embodiment
Piggybacking left-hand rotation Dynamic Signal lamp as shown in Figure 1, comprise the control chip U1 adopting CD40193, control chip U1 connects power supply VCC respectively, clock circuit X and system change-over circuit Y1, clock circuit X can adopt CD4001 chip or crystal oscillating circuit, the present embodiment adopts crystal oscillating circuit, 2 of control chip U1, 3, 6, 7, 12 are connected system change-over circuit Y1 with 13 pin, described system change-over circuit Y1 connects multichannel latch cicuit Y2, binary order is converted to decimal system order, described latch cicuit Y2 connects a LED drive circuit P respectively, LED drive circuit P connects the LED group in left-hand rotation display screen respectively, LED group adopts red and green color LED, described latch cicuit Y2 is also connected in parallel a relay J, the control end of relay J connects wireless controller R, wireless controller R receives the controlled in wireless of traffic control host terminal, the signal that relay J controls latch Y2 exports, after relay J disconnects, latch does not output signal, LED group shows red vehicle and can not pass through, after relay J is communicated with, latch Y2 exports control signal, due to the change of control signal, then LED group alternately flicker, demonstrate the effect of rolling, remind the attention of driver, ensure that efficiency and the safety of driving.
The above, be only embodiment of the present utility model, and those of ordinary skill in the art are in the scope that the utility model discloses, and the change that can expect easily, within the protection domain that all should be encompassed in utility model.
