An Easy to Deploy Street Light Control System Based on Wireless Communication and LED Technology

This paper presents an intelligent streetlight management system based on LED lamps, designed to facilitate its deployment in existing facilities. The proposed approach, which is based on wireless communication technologies, will minimize the cost of investment of traditional wired systems, which always need civil engineering for burying of cable underground and consequently are more expensive than if the connection of the different nodes is made over the air. The deployed solution will be aware of their surrounding's environmental conditions, a fact that will be approached for the system intelligence in order to learn, and later, apply dynamic rules. The knowledge of real time illumination needs, in terms of instant use of the street in which it is installed, will also feed our system, with the objective of providing tangible solutions to reduce energy consumption according to the contextual needs, an exact calculation of energy consumption and reliable mechanisms for preventive maintenance of facilities.

The Design of Intelligent Street Lighting Control System

The paper puts forward a modification plan which combines the wireless communication network with power line communication to reduce energy waste in the city lighting system at night. The system framework is divided into three layers, the backend server controls the centralized controllers through the core network; each centralized controller controls the lamps through the access network; node controller on each street light works as a terminal which controls the light according to the commend receives from the centralized controllers through PLC. The system combines wireless communications, power line carrier, LED circuit constant current drive with PWM stepless dimming technology. The application results show that the system can reduce the electric energy consumption obviously, and the intelligent street lamps operate stably and reliably.

Design of Intelligent Street Light Control System Based on ZigBee

The design uses ZigBee wireless networking chips to connect each street light, ZigBee coordinator of the sub-control center responsible for the formation and maintenance of street lights subnet. The ZigBee coordinator collects all streetlights information and sents to the main control center via GSM module. The main control center sends control commands to the sub-control center via GSM module, and then to each street light controller. It is low-cost, easy to install and maintain.

Smart Street Lighting Control and Monitoring System for Electrical Power Saving by Using VANET

The huge amount of electrical power of many countries is consumed in lighting the streets. However, vehicles pass with very low rate in specific periods of time and parts of the streets are not occupied by vehicles over time. In this paper, we propose a system that automatically switches off the light for the parts of the streets having no vehicles and turns on the light for these parts once there are some vehicles that are going to come. Logically, this system may save a large amount of the electrical power. In addition, it may increase the lifetime of the lamps and reduce the pollutions. This system automatically controls and monitors the light of the streets. It can light only the parts that have vehicles and help on the maintenance of the lighting equipments. Vehicular Ad-Hoc Networks (VANET) make it possible to propose such system. VANET enables the possibility to know the presence of vehicles, their locations, their directions and their speeds in real time. These quantities are what are needed to develop this system. An advantage of using VANET is that there is no need to use specific network and equipments to design the system, but VANET infrastructure will be used. This decreases the cost and speed up the deployment of such system. This paper focuses on the proposal of different possible architectures of this system. Results show that the saved energy may reach up to 65% and an increase of the lifetime of the lamps of 53%.

Distributed Street Lighting Control System with IntelliSense

In this paper, we proposed a novel street lighting system called Distributed Street Lighting Control System with IntelliSense (DSLCSI), and on this basis, five-end architecture, an ItelliSense extension mechanism and a cable theft detection method are described in turn. DSLCSI is presented to overcome the complex configuration, poor scalability and low reliability of cable theft detection methods in existing street lighting system. The results of field application show that DSLCSI provides convenient system scalability and maintainability, and improves the reliability of cable theft detection.

선형적 데이터 전달의 안정성과 부하량을 고려한 무선 센서 네트워크 라우팅 프로토콜

Sensor networks are needed for special purposes such as collecting or transmitting information by using sensor devices, for which various routing protocols have been proposed. Among existing protocols, the modified PEGASIS routing technique is known to be effective when applied to cases with directional transmissions of data. However it does not consider recovery from errors or guaranteeing stability in data transmission, while sensor devices performing repetitive relays and controls are prone to errors. In this paper, a double relay routing protocol for Zigbee based sensor networks where data are transfered reliably with a linear direction. The proposed protocol is effective in the sense that it secures the relaible transmission of data with minimal energy consumption based on a directional data transfer. A streetlight control system has been presented as an application of the proposed protocol.

CMOS single-board computer

Traditional street light control systems only support manual control, photosensitive control, and simple timing control while the energy utilization rate is low and the operators cannot monitor the working state of the street lights in real time, which causes great inconvenience to management and maintenance. This paper designs an intelligent street light control system based on power line carrier communication, which effectively utilizes the power grid resources. In view of the shortcomings in the insufficient distance of power line carrier communication, the signal relay method is adopted to effectively extend the communication distance. It realizes the real-time control and management of street lighting, therefore, meeting the need of intelligent lighting. The experimental results show that the system runs stably and reliably to have great popularization value.
