[IEEE 2018 17th International Symposium on Distributed Computing and Applications for Business Engineering and Science (DCABES) - Wuxi, China (2018.10.19-2018.10.23)] 2018 17th International Symposium on Distributed Computing and Applications for Business Engineering and Science (DCABES) - Intelligent Street Lamp Control System with Dynamic Light Control Function
摘要： In order to solve the problem that the traditional street lamps cannot be controlled dynamically according to the specific conditions of the road at night, an intelligent street lamp control system based on speed and sensor detection information is designed to adjust the number of street lamps in front of the vehicle which are turned on in advance, including the illumination level of street lamps. The system combines Radio frequency identification technology to read the tag information of the vehicle through the reader installed on the street lamp and calculate the driving speed and the number of lamps to be turned on. The sensors are installed on the street lamp node to collect the environmental illumination and the vehicle driving information in real time. According to the fuzzy control strategy, the information is analyzed and calculated and the illumination level of the street lamp is adjusted accordingly. MATLAB simulation results show that the system can adjust the illumination level of the lamp quickly according to the result of the sensors, thus reducing the energy consumption of the system.

Conductive polymer nanoantennas for dynamic organic plasmonics
摘要： Being able to dynamically shape light at the nanoscale is one of the ultimate goals in nano-optics. Resonant light–matter interaction can be achieved using conventional plasmonics based on metal nanostructures, but their tunability is highly limited due to a fixed permittivity. Materials with switchable states and methods for dynamic control of light–matter interaction at the nanoscale are therefore desired. Here we show that nanodisks of a conductive polymer can support localized surface plasmon resonances in the near-infrared and function as dynamic nano-optical antennas, with their resonance behaviour tunable by chemical redox reactions. These plasmons originate from the mobile polaronic charge carriers of a poly(3,4-ethylenedioxythiophene:sulfate) (PEDOT:Sulf) polymer network. We demonstrate complete and reversible switching of the optical response of the nanoantennas by chemical tuning of their redox state, which modulates the material permittivity between plasmonic and dielectric regimes via non-volatile changes in the mobile charge carrier density. Further research may study different conductive polymers and nanostructures and explore their use in various applications, such as dynamic meta-optics and reflective displays.

Solar active envelope module with an adjustable transmittance/absorptance
摘要： A solar active envelope module with a high ?exibility degree is proposed in this paper. The transparent module controls the day-lighting of the room, improving the indoor environment, while absorbing the super?uous solar energy inside. That energy is used to increase the e?ciency of heating, ventilation, and the air-conditioning (HVAC) system of the building. This is carried out through a ?ne control of the absorptance of the envelope module. The active envelope module consists of three glazed chambers with advanced coatings and frames to assure a minimum thermal transmittance while allowing transparency. A ?uid containing heat-absorbing nanoparticles ?ows inside the central chamber and is heated up due to the impinging solar energy. Unlike other systems proposed in the past, which included transparency control systems based on complex ?lters and chemical processes, the absorption of the module is controlled by the variation of the thickness of the central chamber with a mechanical device. That is, varying the thickness of the central chamber, it allows controlling the absorptance of the whole system and, as a result, indoor day-lighting and thermal loads. Therefore, a new system is proposed that enables to: ? Dynamically control the thermal loads and solar day-lighting. ? Improve the thermal performance of building envelope and reduce the energy demand of the building. ? Increase the solar fraction of the heating and cooling, and reduce the thermal losses improving the e?ciency of the building. The solar active device proposed in this article is protected by a Spanish patent application (Fundaci ′on Tekniker, Fundaci ′on CENER-CIEMAT, 2014).
