Embodiment 11

[0051]Present traffic lights are made up of 2-3 signal lamps 1, and each signal lamp has 2 electric wires to lead to master controller 4. The wire has both the function of powering the signal lamp and the function of signal transmission. Each lamp is independent of each other, there is no parallel or series relationship. At the same time, the wires are relatively thick, and when the quantity is large, the cost is very high. If row of lights has 100 signal lamps 1, if each signal lamp is to connect master controller 4 with electric wire, then need go up 200 electric wires. The average length is 50 meters, and the total length can reach 50*200=10000 meters, and the total cost is very high.

[0052] A row of lights, the row of lights is composed of 100 signal lights and 100 driver chips 2 in a row, arranged along the exit of the intersection. The length of the row of lights is 100 meters, and there is a signal light 1 every 1 meter, and the distance between two adjacent signal...

[0055] Currently commercially available LED running water marquee can be more than 10 meters in length, with 20-60 LED lights per meter, each LED light is about 0.1w, and DMX512 programmable controller is used as the main controller 4 . The DMX512 controller has 512 output channels and can control up to 170 full-color nodes. The DMX512 controller is programmable and can generate control effects arbitrarily. The DMX512 controllers are connected by network cables, so that multiple DMX512 controllers can work together, and the number of nodes controlled can be almost unlimited. The CD4066 switch chip is a chip used for circuit on-off, which can control the on-off of up to 4 circuits at the same time.

[0056] An intersection with four exits each with a set of lights. Each group of lights has a total length of 100 meters and is arranged longitudinally along the exit lane of the intersection. like figure 2 As shown, each row of lights is composed of 100 signal lamps 1, 100 CD4...

[0059] NordicVLSI company produces nRF905 wireless transmission module 7, which is a wireless transmission module with a transmission range of 300-500 meters, and is often used for remote control and data transmission. For example, a commercially available water distributor is generally composed of a master controller 4 and multiple control valves. The master controller and each control valve are respectively connected to the nRF905 wireless transmission module. Remotely control the water supply, water stop, and water volume of each branch water pipe. There are dozens of control valves for the water separator, which can be used in floor heating systems, central air conditioning, water supply projects, etc. At present, there are LED lanterns, and thousands of small lanterns are controlled by Bluetooth communication.

Abstract

In a batch variable area intersection, a row lamp is needed to guide a vehicle in a left turn waiting area to run into a retrograde area. The length of the row lamp is more than 50-100 meters, and thenumber of required signal lamps is above 50-150. The length of the row lamp is large, and the number of signal lamps is large. Each signal lamp requires two wire loops as power supply and control circuits, and the row lamp is difficult to erect, which affects city appearance. The row lamp only has two power supply lines. Each row lamp or a driving chip is connected in parallel to the power supplylines so as to greatly reduce the total length and the complexity of the power supply lines. The occupied height of the row lamp, the number of signal lamps and line complexity are reduced.

Description

technical field [0001] The invention relates to the field of batch-changing intersections, traffic lights, and LED lights. The bar lights of the invention are used for signal control at intersections, and are used to guide vehicles in left-turn waiting areas to start and turn left. Background technique [0002] During urban planning and construction, in order to avoid affecting the beauty of the city and avoiding the feeling of splitting the sky of the city, the use of pull wires and scaffolding is strictly restricted in the sky above the road. Especially at the intersection, where the flow of people and vehicles is dense, the perspective view is very important. In urban construction, it is better to increase the investment of 300,000 to 3 million yuan, but also to make the wires and cables at the intersection go underground, which shows the importance of the landscape at the intersection. [0003] Batch variable area intersection is an intersection structure described in p...
