基于OPS系统与抗干扰技术的轨道交通站台显示屏设计OA

To address the deficiencies of existing Passenger Information System(PIS)display devices at rail transit platforms in terms of environmental adaptability,anti-interference capability,and functional expandability,a design scheme of platform display screen based on the Open Pluggable Specification(OPS)system and anti-interference technology is proposed.The scheme adopts a modular hierarchical architecture,integrating an LCD display module,an OPS core control module,a multi-interface adaptation module,a stable power supply module,and a dual protection module.The anti-interference performance is enhanced through the collaborative design of hardware and software filters.Tests show that the display screen meets the requirements of high-interference platform scenarios,and possesses the capabilities of modular rapid maintenance and functional expansion,making it suitable for integration applications in various rail transit PIS systems.
