Analysis and Research of Automatic Broadcast Filter Circuit
全自动广播滤波电路的分析研究

摘要

随着全自动运行系统的快速发展，无人驾驶列车越来越普及，对旅客信息系统的要求越来越高，因此可靠的全自动广播是保证乘客到站下车的根本保障，在应急情况下引导并疏散乘客，能够有效避免危害的扩大。由于全自动驾驶车辆的环境复杂，有很多未知的电磁干扰。因此，本文提出一种可以提高广播主机抗电磁干扰能力的方案，可以提高全自动广播播报的可靠性。

Abstract

With the rapid development of automatic operation systems, driverless trains are becoming more and more popular, and the requirements for passenger information systems are getting higher and higher. Therefore, reliable automatic broadcasting is the fundamental guarantee for passengers to get off at the station. Guiding and evacuating passengers in emergency situations can effectively avoid the expansion of hazards. Due to the complex environment of fully autonomous vehicles, there are many unknown electromagnetic disturbances. Therefore, this paper proposes a scheme that can improve the ability of the broadcast host to resist electromagnetic interference, which can improve the reliability of fully automatic broadcast broadcasts.
