摘　　要：为了提高轨道车辆车厢LED照明控制系统的抗干扰能力和散热性,实现自动调光,设计了控制系统的硬件方案。设计了以WTB(绞线式列车总线)和MVB(多功能车辆总线)为基础的通信网络,结合亮度采集模块采集环境亮度信息,应用PWM技术对LED亮度进行自动调节。实验结果表明,设计的轨道车辆车厢LED照明系统硬件散热性好,发光稳定,能够根据外界环境变化自动调光,亮度的调节误差小于1%,验证了硬件设计的合理性。In order to improve the anti-interference ability and heat dissipating capability of railway vehicle LED lighting con trol system and achieve automatic dimming ,a scheme of the hardware of the control system is designed. WTB （stranded wire train bus） and MVB（muhifunction vehicle bus） are used as the basis of communication network. PWM technology is used to automatically adjust the brightness of LED. Experiment results show that the design of LED lighting system hardware of railway vehicle is with good heat dissipation, lights stability, and can adjust light automatically according to the external environment change with brightness error less than 1%.The design of hardware can be proved to be rational.
