Wiring Arrangement Method of Led Traffic Signal

Image
  Ⅰ. The importance of LED traffic signal lights   Intelligent transportation is the development direction of the future transportation system. Intelligent transportation effectively integrates advanced information technology, data communication transmission technology, electronic sensor technology, control technology and computer technology in the entire ground transportation management system. What it establishes is a real-time, accurate, and efficient comprehensive transportation management system that works in a wide range and all-round way. Among them, the most important thing is the use of traffic lights.   LED crosswalk signal lights  are an important part of traffic signal command and the basic language of road traffic. Traffic lights are placed at intersections in every city by urban planning. It is precisely because they direct traffic day and night that traffic can remain stable and unobstructed. LED traffic signal lights  play an irreplaceable role i...

What Factors Should Be Considered in the Design of Solar Road Studs?

Image
  There are many forms of solar road studs, and the installation positions are also different. No matter what kind of solar road studs, some factors need to be considered when designing.   Here are some factors to consider.   1. The sealing performance and brightness of solar road studs   If the solar road studs  are not completely sealed, water will leak, which will cause a short circuit, and the consequences will be catastrophic. Therefore, for a qualified solar road stud, its sealing performance must be satisfactory.   Solar road studs must be able to actively emit light. The outline and edge of the road are drawn to the greatest extent, which is one of the most important features compared to ordinary reflective road studs. In terms of this indicator requirement, the relevant standard of the Ministry of Transport is 2000MCD.   2. The long-term stability of the brightness of solar road studs   Another important factor that determines the life of...

The Role of Geomagnetic Sensors in the Realization of Parking Guidance and Billing Functions

Image
  Geomagnetic sensors  can be used to detect the presence of vehicles and vehicle type recognition. The data acquisition system plays a very important role in the traffic monitoring system. The geomagnetic sensor is a key part of the data acquisition system. The performance of the sensor plays a decisive role in the accuracy of the data acquisition system.   Geomagnetic sensors can be used to detect the existence and model of a vehicle. It uses the influence of the earth's magnetic field when vehicles pass the road to work. And this kind of sensor is very compact and convenient, the sensitivity is also first-class, the construction amount is very small, but its service life is very long, and the damage to the road surface is also very small.   1. The working principle of geomagnetic sensor in parking service   The geomagnetic sensor is the front-end sensing device of the ground guidance system, which can accurately lock the stay and departure time of the vehicle...

Combination of Geomagnetic Sensors and Traffic Signal Lights

Image
  When you drive a vehicle on the road, do you often encounter a coincidence: After the green light is on, it often turns to red after the last vehicle has passed, and the time is very accurate. In fact, this kind of experience is not a "coincidence", thanks to the geomagnetic sensor buried under the road. In conjunction with intelligent traffic lights, in order to further improve the traffic capacity of urban roads, geomagnetic sensors are playing a very important role, allowing traffic lights to "change their faces" with traffic flow.   1. To understand geomagnetic sensors   The geomagnetic field is an inherent resource of the earth, which provides a natural coordinate system for aviation, aerospace, and navigation, and can be used for the positioning and orientation and attitude control of spacecraft or ships. Magnetic navigation technology that uses the spatial distribution of the earth's magnetic field is simple, efficient, reliable, and anti-interference. ...

Specification for mounting height of LED traffic lights

Image
  Traffic signal  lights are divided into motor vehicle signal lights, non motor vehicle signal lights, crosswalk signal lights, direction indicator lights (arrow signal lights), lane signal lights, flashing warning signal lights, road and railway level intersection signal lights. The requirements for installation height of various walk traffic light s are also different.   The installation height requirements of LED traffic lights  are as follows:   1. Installation height of motor smart traffic light , direction indicator light and flashing warning light:   a. Overhung mounting, the height is 5.5m ~ 7m;   b. Column shaped installation, the height shall not be less than 3m;   c. Installed on the overpass body less than 6m, it shall not be lower than horizontal and vertical clearance above bridge deck;   d. When the installation height of the additional signal light is less than 2m, the signal light shell shall not have sharp protrusions. ...

Benefits of Pedestrian Crossing Road Studs

Image
  Road studs are very useful road safety products on the road and have powerful advantages. Solar road stud is a road stud powered by solar energy. It is a new era alternative to traditional reflective road studs (commonly known as CAT EYES). Solar road studs can provide drivers with clear road edge markings and directions at night and under severe weather conditions (such as fog, rain, etc.). Therefore, it can reduce the accident rate by more than 70%, thereby reducing the impact on the environment and saving costs.   Ⅰ. Knowledge about crosswalk nails   Solar road studs  can be used as permanent or temporary lighting equipment in danger. Solar road studs, contour lines and beacons were developed to improve road safety, but can also be used in many other applications, such as agricultural applications and off-grid garden decorative lighting.   In order to improve the safety factor of zebra crossings and reduce the potential dangers that pedestrians face on zebr...

The Advantages and Development of LED Traffic Lights

Image
  After generations of technological improvements, LED walk traffic light s  have greatly improved their luminous efficiency. The light effect of incandescent lamps and halogen tungsten lamps is 12-24 lumens/W, fluorescent lamps 50-70 lumens/W, sodium lamps 90-140 lumens/W, most of the power consumption becomes heat loss. The improved LED light efficiency will reach 50-200 lumens/watt, and its light monochromaticity is good, the spectrum is narrow, and it can directly emit colored visible light without filtering.   Ⅰ. Advantages of LED traffic signal lights   1. Long lifespan   The working environment of traffic light s is relatively harsh, with severe cold and heat, sun and rain, so the requirements for lamps are relatively high. The average lifespan of incandescent bulbs for general signal lights is 1000h, and the average lifespan of low-voltage tungsten halogen bulbs is 2000h. The resulting maintenance costs are high. The LED traffic signal lamp has no filame...
