Intelligent signal control scheme based on intersection video images and MEC computation
With the acceleration of urbanization, problems such as traffic congestion and environmental pollution are becoming more and more prominent. Most of the traditional traffic signal systems rely on utility power supply, which not only increases the operation cost, but also imposes a certain burden on the environment. In order to solve these problems, this solution is an intelligent traffic intersection solution based on solar and wind power supply and energy storage, aiming to realize energy saving and emission reduction, reduce operation cost and improve traffic management efficiency.
Program Overview
This solution integrates surveillance cameras, radar and fill-in lights on poles at traffic intersections and utilizes wind and light energy for power supply. The stability of the power supply is guaranteed by an advanced energy storage system and the dependence on utility power is minimized. The main goal is to realize intelligent management of road surveillance and traffic signals, and at the same time to save significantly on electricity costs.
Program Details
Power Supply System
1.1 Solar Power Generation
Highly efficient solar photovoltaic panels are installed on the poles at traffic intersections to capture daylight and convert it into electricity. The photovoltaic panels are configured according to actual demand to ensure stable power generation capacity under different weather conditions. The advantages of solar energy lie in its wide applicability and long-term economic benefits, and the efficiency of power generation can be effectively ensured through regular maintenance.
1.2 Wind power generation
In conjunction with the riser structure, a small wind turbine is installed for capturing wind energy and converting it into electricity. Wind power can provide additional power support when solar power generation is insufficient. The selection of wind turbines should be adjusted according to the wind speed data of the area where the intersection is located to ensure that the power generation efficiency is maximized.
Energy Storage System
To ensure the continuity and stability of power supply, this solution is equipped with high-performance energy storage batteries. The energy storage system is capable of providing supplementary power when solar and wind power generation is insufficient. Through the intelligent Battery Management System (BMS), the status of the battery is effectively monitored to ensure the service life of the battery and the reasonable distribution of power. Meanwhile, the link to the utility line allows seamless switching to utility power supply when the energy storage runs out in extreme weather conditions, guaranteeing the stability of the business.
Intelligent Transportation Equipment
3.1 Surveillance Camera
High-resolution surveillance cameras are installed on poles to realize all-weather road monitoring. The cameras are equipped with night vision function, which can clearly capture images in low-light environment. Real-time transmission and analysis of video data is realized through the cloud platform to improve the accuracy and response speed of traffic management.
3.2 Radar System
Radar system is used to detect vehicle flow, speed and other information, assisting traffic signal lights for intelligent regulation. The data fusion of radar and monitoring camera helps to realize dynamic traffic signal control and optimize traffic flow.
3.3 Fill light
Fill light is integrated in the riser for enhancing the monitoring effect at night. The fill light adopts high-efficiency LED lamps, which can automatically adjust the brightness according to the ambient light to ensure the normal operation of the surveillance and traffic management equipment at night or under adverse weather conditions.
Signal Light System
In order to minimize the reliance on utility power, the traffic signal system is also powered by solar and wind energy as much as possible. The power supply design of the signals will take into account high-efficiency LED luminaires to reduce power consumption. Through the intelligent regulation system, the working time and cycle of the signals will be optimized to improve traffic smoothness and safety.
Communication Network System
The whole system builds a dedicated communication network through industrial switches to interconnect the sensing nodes, cameras, signal light controllers at each intersection, and the power generation and energy storage systems. It adopts star or ring structure network and connects with the management center to ensure real-time and at the same time, it is convenient for the classification management and control of the overall business.
System Management and Maintenance
All equipment is equipped with remote monitoring function, which is convenient for real-time control of the system’s operation status. Maintenance personnel can perform remote troubleshooting and maintenance operations through the system management platform, reducing maintenance costs and time. Regular system inspection and maintenance are carried out to ensure the long-term stable operation of the equipment.
The intelligent traffic intersection solution based on integrated solar and wind power supply and energy storage provides an efficient and environmentally friendly traffic management solution by integrating renewable energy, advanced energy storage technology and intelligent transportation equipment. The solution not only significantly reduces operating costs, but also enhances the intelligence of traffic management. We believe that by implementing this solution, you will be able to obtain a more efficient and safer transportation system while saving energy and reducing emissions.
