Qingdao to enable solar powered traffic signs

Reporter from the Qingdao City Traffic Police Department learned that in order to alleviate the haze or other low visibility weather conditions of traffic congestion is not smooth,  Solar Traffic Sign ,the low road traffic accident occurs, the traffic police department took the lead in the installation of the enabled 200 solar active luminous sign. Since June began to traffic police detachment facility in Qianhai road added active light guiding sign, ready to install the luminous sign had 40 sides, green led warning strobe light involving to the Zhongshan Road, Hubei Road, Hunan Road, 10 road. As of now, 27 sides have been installed, the remaining 13 will be installed in the near future.

Use the rules of LED traffic signs

LED traffic signs is an important measure to guarantee the traffic safety, smooth. There are led traffic signs many types of traffic signs, can be used in various ways to distinguish: main signs and auxiliary sign; the movable markers and fixed signs; lighting signs and luminous signs and reflective signs; variable message signs and reflect the driving environment change.
LED traffic signs of Solar Traffic Sign general shape using the rules are as follows:
A. is an equilateral triangle: used for warning signs;
B. round: for the ban and indication;
C. inverted equilateral triangle: for the "slow to yield" ban signs;
D. octagon: "stop line" Road traffic signs prohibition signs for;
E. fork: for the "railway crossing fork symbol" warning sign:
F. Square: for road signs, warning, ban and indication, tourist area signs, auxiliary sign, sign sign lamp.

LED traffic signs is divided into several categories

The main LED traffic signs can be divided into four. The indicator; usually round and rectangular, blue and white pattern. Used to indicate the moving vehicles and led traffic signs  in the specified direction, location. Such as straight line, turning left and right, parking, bypass etc.. The warning signs: usually an equilateral triangle (or diamond), yellow (white) background and black (red) side, black (or dark blue) pattern. Used to warn drivers to pay attention to the danger the front sections of existence and the measures to be taken. If notice of intersection, the road bends, a railway crossing, slippery road, road, rough road, possible rockfall merging traffic etc.. The prohibition signs: usually round, Traffic warning sign  red edge, red slash black pattern. According to the street, road and led traffic signs of vehicles marked ban or proper limits. Such as the prohibition of passage, no parking, speed limit, limit the weight, width limit etc.. The guide sign: usually rectangular, blue (green) and white and white pattern. Used to indicate the village city boundary, the direction to the destination, distance, freeway access, service area and a famous place, and along the way various guide. Such as the national highway number, milepost, Solar Traffic Sign  meter pile, boundary tablet, guideposts, brand, and the highway entrance, gas station, repair signs, parking station etc.. The auxiliary tags attached to the major mark up added effect. LED traffic signs can be divided into said vehicle type, representing the time, said interval range and said distance four. Can't set up a separate auxiliary sign. Auxiliary sign Signs attached to the main under the sign, the play a supporting role, at that time, vehicle type, region or the distance, warning, prohibition and other types of reasons.

Selection and application of LED traffic signs reflective material

1) led traffic signs principle on the road at all levels should use reflective material logo made surface. 2) traffic signs, a road and city trunk road should adopt a ~ three grade led traffic signs  film; two or three highway and the general city road led traffic signs should adopt the reflective film of level four or above. Four or five grade reflective film can be used for other road four highway and traffic volume is very small. 3) curve section of highway, a highway, city expressway on the sign, led flashing traffic sign  intersection and city area, should adopt the above three levels of reflective materials. 4) of portal city expressway, expressway and cantilever logo, to obtain and roadside sign reflecting effect of quite, should choose road side marker for reflecting film rating for the reflective material is high, or the door frame and cantilever mark symbol characters on the warning signal light  to the reflector, to improve the visibility of the night. In important sections of the condition, also can use lighting sign. C led traffic signs) rules and reference color samples of color.

The power supply design of LED traffic signs

In order to change the traditional highway LED traffic signs requires electricity supply, can not move, marking the disadvantage of single, designed a new generation of highway led traffic signs  safety facilities -- mobile solar traffic sign vehicle. Its mainly by the battery, transmission part, control part, display part and a car body. The design structure is simple and reasonable, the bidirectional power supply solar and battery, warning distance, independent working for a long time, R & D warning icon display system can display various icons in Solar Traffic Sign  with national standards, when in use can be replaced at any time, and design a set of automatic tracking system for solar panels, can make the rate to improve the utilization of solar energy, energy saving, emission reduction, energy, efficiency purposes.Led traffic signs is especially suitable for in no led flashing traffic sign  highway, non fixed construction (maintenance) site and bend, mountain high risk areas, but also can play its convenient movement characteristics under emergency.

LED traffic signs function

According to estimates, the driver needed in the driving vehicle information, accounting for 90% of the led traffic signs  information. Visual characteristics such as visual depth, width, eye movement, color, luminance and glare impact identification, speed judgment, is the basic elements to consider LED traffic signs settings. The road users, almost all information through the visual transmission reception, so setting LED traffic signs, we should pay attention to the significant, led flashing traffic sign  to understand, credibility and positioning. The driver's driving task includes obtaining information, processing information, select the action plan, the implementation of action plans, and through this process is repeated to observe the result of decision. Because of the relationship between human behavior and the limitation of the driver, vehicle and road environment makes the process very complex. The installation of traffic signs, also should consider the driver's expected value, reaction time and short-term memory characteristics. Only fully consider the behavior of the road users, traffic signs are effective. This article refers to "not familiar with the surrounding road network system of road users" is not to say that the warning signal light  users without knowledge of the ring around the altar, but through the map or other means of inquiry, the destination and route to understand, LED traffic signs guidelines can then reach the destination.

LED traffic signs support

(1) warning, ban, indication and small size guide sign should adopt the single column type support, in solar led traffic sign ,  the double column or columns support. (2) when meets the following conditions, according to the needs of the cantilever rack, or hanging support (layout content less, should adopt the cantilever): The LED traffic signs reached the design capacity; The design of the interchange is complicated; The one-way three or more than three lane; The interchange led flashing traffic sign  is near; The outlet for multi lane; The large vehicle proportion is large; ⑦ across multiple interchange, consistent sign information set position;; The roadside installation space or by occlusion; Hub of the connection between the two highways at; The off ramp is left to export; The plane intersection signs or in interchange the deceleration lane of the starting Solar Traffic Sign  of the export notice signs. (3) are arranged along the highway overpass bridge structures, the roadside is provided with high retaining wall, light bar, LED traffic signs in order to meet the requirements of highway construction clearance, can use the attached type support.

4 battery life. The storage battery is the battery, according to its internal material is divided into several lead-acid batteries, nickel hydrogen batteries, lithium batteries and other categories. In accordance with the outdoor environment traffic battery is Ni MH and Li ion battery, because relatively speaking them in high and low temperature properties, volume and capacity ratio, environmental protection, life is better than lead-acid batteries. If in order to maintain statistical lead-acid battery cycle number 60% capacity in about 400 times, Ni MH battery in about 500 times, lithium battery in about 600. If in order to maintain statistical lead-acid battery cycle number 60% capacity in about 400 times, Ni MH battery in about 500 times, lithium battery in about 600. In this cycle the so-called refers to the battery full full, full as a cycle. But in fact the solar signs need to consider the rainy days, the battery is most of the time in the free 1/5 charge when charging, the cardboard traffic signs  on the shallow charge floating charge state of the work can be greatly extended battery life. But in fact the solar signs need to consider the rainy days, the battery is most of the time in the free 1/5 charge when charging, the light on the shallow charge floating charge state of the work can be greatly extended battery life. Even so, solar signs if using lithium as usual, life is only about 4 years. From the above several solar signs of main components can be analyzed: the battery is the bottleneck that restricts its life. From the above several solar signs of main components can be analyzed: the battery is the bottleneck that restricts its life. The products of the battery should pay attention to moisture at the same time, should be easy to replace.

The role led traffic signs

(1) solar led traffic sign to warn vehicles, pedestrians mark hazardous locations;
(2) prohibition signs are prohibited or restricted vehicles, signs pedestrian traffic behavior;
(3) directional signs are indicative of the vehicle, pedestrian travel signs;
(4) passing electronic traffic signs are guiding the direction, location and distance information signs.
Auxiliary logo is attached under the main sign, play a supporting role in the mark description, points represents time, vehicle type, region, or distance, warnings, and other types of reasons for the ban.

The working principle of LED traffic signs

The eye-catching solar logos, daytime solar panels absorb sunlight, converts solar energy into electric energy, led traffic signs  in the energy storage device, in the evening, energy storage devices in the electric energy into light (automatic control through photoelectric switch), to draw the pattern profile of light emitted by LED, communication traffic information.
Early LED traffic signs, is basically a light box, circuit, controller, batteries are arranged in the box body. Its drawbacks: the box is too heavy, the solar panel the solar traffic sign  is too large, is not conducive to the packaging, transport, in the transport process, often causing internal damage; cell and circuit are sealed in a box body, should not be replaced; the box is too large, the seal is difficult to control.
LED traffic signs is based on a single crystal silicon solar cell components for energy, without network support, not subject to geographical constraints, the use is very convenient! It is the use of solar cells to the conversion of sunlight into electricity stored in signs, when night fell, the dim light or rainy weather, the line of sight is not good situation, LED LED traffic signs to automatically start flashing light, especially bright, eye-catching, with strong warning function. Particularly in the led flashing traffic sign field and dangerous areas without power highway, often moving, the active luminescent LED traffic signs reflects the special warning function, the visual distance is a reflective film as 5 times the sign reflective material brand, its dynamic effect is also common sign board which can not be substituted.

The development of LED stars, solar traffic signs

Made a simple LED traffic signs

We need to prepare tools, to do good work, must first sharpen his tools. If not familiar with the application of the tool, to find something more simple. First practice on the hand and then have a look the construction drawings, the required parts and lines are labeled on the diagram. led flashing traffic sign parts need: 10K resistance X2, 4.7K resistance x1, a 430 resistor x4, a potentiometer 1mx1, ceramic capacitors x1, elko4,7fx1, elko100fx1, bc327x1, ne555x1, IC transistor socket x1, PCB hollow plate x1 Prepare the materials needed to start, the plane to find a job first, put all the parts according to the circuit chart position is inserted into a circuit board pre opened hole, and then connecting element used wire pin. That is very simple, it requires each DIYer patient. IC socket is the first soldered to the circuit board, while the NE555 through the socket is installed, this can avoid the novice not careful because the welding time is too long or the welding tool is not anti-static measures and burnt integrated circuit. Inspection can have a look after electrifying effect! If welding is correct, after power can work. The adjustable potentiometer to adjust the flash frequency. Of course, here is a demonstration! You can put the solar traffic sign  into any color other than red, also can buy a light control panel to control led to achieve more dazzling effect.

led traffic signs are divided into seven categories

(1) Warning signs: led traffic signs Warning vehicles and pedestrians dangerous place logo. 

(2) prohibition signs: prohibit or restrict the vehicles, signs pedestrian traffic behavior. 

(3) indicator: Indicates vehicles and pedestrians traveling logo. 

(4) A directional sign: informative traffic signs Pass road direction, location, distance signs. 

(5) Tourist Area Codes: providing tourist attractions direction, distance signs. 

(6) construction safety road sign: Notice of road construction zone traffic sign. 

(7) Auxiliary signs: Help attached to the primary use of the logo mark began.
