AISP IP Network PA System for Wuhan Liyuan Subway Station

Wuhan East Lake Liyuan Square, located in the northwest of East Lake and adjacent to the Second Ring Road, runs parallel with the Rail Transit Line 4. It covers an area of 35,400 square meters, including 17,500 square meters of green space. This square is a comprehensive square that integrates transportation, sightseeing, leisure, and landscape.

As a modern transportation hub, the subway station's public broadcasting system should meet modern usage requirements, providing convenience, quickness, and efficiency for both staff and passengers. The subway station's broadcasting system is primarily used to broadcast train dynamic information, station service information, and also provides services such as paging, person search, announcements, background music, and community broadcasting. In the event of a disaster, it also serves as a disaster relief broadcasting system, organizing passenger transportation operations, guiding passenger flow, ensuring traffic safety, and effectively conducting passenger transportation management and services. The system features automatic broadcasting, semi-automatic broadcasting, manual broadcasting, and emergency broadcasting functions; it allows for the selection of any one or multiple broadcasting zones in the station for broadcasting, either individually, in groups, or in full; in the event of a fire, it switches to fire emergency broadcasting, which has the highest priority.

Based on the actual needs of the subway and relevant design standards,AISP has designed a set of IP Network PA system for Liyuan Subway Station, covering the ground and underground areas including Liyuan Subway Station. Ceiling speakers are installed at the front ends of subway platforms, office areas, concourses, and other locations, with IP network adapters, constant voltage broadcasting amplifiers, main and backup amplifier switchers, and other equipment. According to the specific conditions of each area, reasonable front-end equipment is configured to ensure the stable operation of the broadcasting system.

Currently, the subway broadcasting system is developing towards digital processing and networked transmission. Compared with traditional analog broadcasting systems, and combined with practical application cases of network digital broadcasting systems in subways, it is not difficult to find that digital broadcasting systems offer more flexible operation, higher system stability and reliability, as well as better energy efficiency and environmental protection. It is believed that in the near future, digital broadcasting systems will be widely used in the subway sector, providing more intelligent broadcasting means for intelligent rail transit.
