Abstract.With the continuous development of information technology, the application level of city information is increasing. A model based on Internet of street lamp illumination by automatic control system is designed in this paper. Based on intensity of illumination, and traffic noise, the information such as temperature and humidity automatic data collection and information processing, the system sets the corresponding weights of each measurement parameter, through the corresponding algorithm to judge the different road and weather conditions and make the corresponding instruction, implement different road and weather conditions of intelligent street lamp illumination adjustment function.We designed a partial state observer to estimate it easily utilizing the vibrations of car-body and bogie frame. And the vertical vehicle dynamic system model was built and simulated with the track irregularity as excitation to product the corresponding vibrations, and thus, to validate the feasibility of the observer, as well as the observer performances of estimation errors and convergence time. In this paper, we study the moduli space 2 3 of time-like pseudo circles in 1 3 . Up to Möbius transformations, all the geodesics in 2 3 are determined to form a one-parameter family of time-like pseudo circles on a generalized helicoid in space form 1 3 (1), 1 3 (−1), 1 3 (0)，resp.
