In order to solve the problems of large energy consumption existing in tunnel lighting control system, an automatic control system of tunnel lighting is designed based on stepless control method. The tunnel lighting control model is established based on “Specifications for Design of Ventilation and Lighting of Highway Tunnel (China)”. Simulation of tunnel lighting control based on the establish...

Energy efficiency represents one of the main challenges in the engineering field, i.e., by means of decreasing the energy consumption due to a better design minimising the energy losses. This is particularly true in real world processes in the industry or in business, where the elements involved generate data full of noise and biases. In other fields as lighting control systems, the emergence o...

This paper presents a design for intelligent control system of scene adaptive semiconductor lighting. The new design contains the host computer and the terminal in a control network. The lighting effect patterns are edited by the software on the host computer, then the lighting scene data is transported to the terminal through network. The terminal is a sub-controller based on the embedded syst...

The localization of people and objects in different environments is an essential prerequisite for many applications in navigation, robotics, machine control and monitoring. The limiting factor for many applications is the indoor environment in which the Global Satellite Systems work only partially or cannot function at all. Currently radio frequency (RF) based methods are being increasingly imp...
