Security Protection for Intelligent Road Lamp Control System

Abstract: According to the current situation of relatively limited smart street light security control,this paper proposes a 128-bit ciphering solution to project smart street light control,based on security chip and key management system.Leveraging various technology including encryption and digital authentication,this solution greatly reduces the security control risks when street lights are attacked,without affecting system performance.

Intelligent street lighting using traffic & ambient lightning

Abstract: The proposed system deals with remote streetlight monitoring and controlling system. Street light system's includes a threshold situation in time and automatic control pattern for conservation of electricity by making switch ON light automatically during vehicles passing & light will switch OFF later. It results in conservation of electricity in comparison with existing streetlamps in operation during nights. The proposed system can be widely applied in various places with controllable in time such as Schools, Stations, Roads and Industries and so on. The proposed system is constructed based on the Microchip's PIC16F Microcontroller.

A feasibility analysis of retrofitting existing roadway lighting infrastructure with LED technology

Abstract: LED technology has advanced towards use in high intensity lighting purposes. LED luminaires have a significantly longer expected lifetime than traditional highintensity discharge lighting systems. Due to these recent improvements in LED technology, there is a growing need for a comprehensive method to analyze the applicability of LED luminaires for use on major routes and roadways. This research investigates the acceptability of LED luminaires for use on major roadways through a feasibility analysis using data collected at various LED street light testing sites. Nine distinct LED luminaires were analyzed in field testing. The field data was then analyzed and compared to manufacturer’s claims, or values produced by the manufacturer’s IES file. Sustainability was incorporated through an economic analysis, environmental impact analysis, and a stakeholder analysis. Each of the nine luminaires in the field feasibility study were also economically analyzed. An economic life cycle approach was used to analyze the economic requirements for each luminaire. The life cycle approach includes cradle to grave costs, including installation costs, operation and maintenance costs, and removal and disposal costs. A sensitivity analysis was also performed to identify the most critical variables within the life cycle analysis. The increased electrical efficiency provided by LED luminaires causes a decreased environmental impact through reductions in CO2 production and reduced water consumption. Social sustainability was analyzed through the discussions and interviews with the penultimate end users, state and local agencies. Plans for testing products for future implementation are also discussed.

Detecting Inefficient Lighting Solutions: Step-by-Step Geographic information system (GIS) Technique

Abstract: Outdoor lighting is used to illuminate roadways, parking lots, yards, sidewalks, public meeting areas, signs, work sites, and buildings. It provides us with better visibility and a sense of security. When well designed and properly installed, outdoor lighting can be and is very useful in improving visibility and safety and a sense of security, while at the same time minimizing energy use and operating costs. But, because nobody thought at this, most street lights shine light not only on the nearby ground, where is needed, but also miles away and skywards. Thus a large fraction of the light is lost, at consumer expense and without his/her consent. In the other hand, shortage in street light may cause more crimes as well as accidents. Most of the wasted or short light comes from the poorly designed street lights. Billboards, decorative lights, poorly shielded security lights are part of the problem too, but the main culprit for the waste and ugly glow one sees above one's head at nights is from the streetlights. Thus, recent computer technology gives us tools to be employed for testing the quality of light. Geographic Information System (GIS) software could be utilized to achieve that mission through applying mapping technique. This technique could analyze digital photographs and define light polluted areas as well as bad lighted. This paper reveals that step by step technique, which employs hybrid technologies to solve such problem for better planning decisions.

Intelligent solar street light control system and control method thereof

Abstract: The invention discloses an intelligent solar street light control system and a control method thereof. The system comprises at least a mono-lever system with a wireless communication interface and a manager with the wireless communication interface; wherein, the mono-lever system comprises a controller, an LED lamp, a solar panel and a storage battery; the controller monitors and records the operating data of the solar panel and the storage battery; the manager can modify the parameters of the mono-lever system and store the parameters in the controller; the manager is connected with a host. By adopting the technical proposal, the invention can solve the centralized control problem of independent solar street lights, accurately set, control and monitor each street light in the whole solar street light system, inquire the working conditions of each street light, help the street light management personnel timely master the operating states of each solar street light and find out the hidden problems of the street lights so as to timely repair the street lights to prevent accidents.
