Mass Transit Intelligent Lighting System

Abstract With the constant improvement of the rapid development of economic and social infrastructure, rail transit construction business has been steadily progressing in the modern rail transit station is a very important part。 According to the proportion of the current consumption of the illumination is gradually increased to 19% power。 In order to use a stressful situation can be eased, all countries need to improve lighting efficiency。

    This paper analyzes the various different types of stage lighting systems, they have their drawbacks, intelligent LED lighting system design based TMS320LF2407A DSP design is designed for these shortcomings, this system has an adaptive dimming function。 This article describes the LED environmentally friendly, high efficiency, long life and other characteristics。 Finally, the connection method。 System design dimmable LED size DIM pin PWM wave signal for controlling the power supply from the DSP BP2808 current output to adjust the LED luminous intensity, the purpose is to achieve adaptive dimming。 CAN bus reached the highest rate of 1Mbit / s, transmission distance of up to 10km, up to 110 nodes, which can not only meet the design requirements of real-time systems, but also improve the convenience of the system。

This paper has 17 figures, 3 tables, 41references。
