AISP Audio & Video System Implemented at Xuzhou National Basic Meteorological Station

As one of the grassroots meteorological stations in Jiangsu Province with the most comprehensive forecasting and observation services, Xuzhou National Basic Meteorological Station is located in the Jiulishan Airport area in the northern suburbs.It undertakes multiple core tasks including surface meteorological observation, upper-air meteorological detection, and agricultural meteorological observation, serving as a critical hub for regional meteorological disaster prevention and mitigation, agricultural production support, and upgraded meteorological services

To meet the requirements of smart meteorology construction, the station has comprehensively upgraded its venue facilities, creating a modern workspace integrating daily operation, conference discussion, training, and command scheduling.The implementation of a professional audio-video system has become essential support for the efficient operation of the new venue. Precise audio transmission and efficient site control are critical to meteorological work.AISP has successfully delivered a multi-scenario audio-video solution for Xuzhou National Basic Meteorological Station.Featuring professional sound reinforcement, intelligent central control, and outdoor public address systems, it establishes a stable and intelligent audio-visual environment for multiple conference rooms, empowering meteorological conferences, training, and emergency command scheduling.

The new venue includes various conference spaces: small business discussion rooms, multi-person conference halls, etc.With large spatial differences and diverse application scenarios, the audio-video system is required to meet strict standards:zone-based adaptation, stable and precise performance, and easy operation.It must ensure clear voice transmission during multi-person conferences and smooth display of high-definition materials such as satellite cloud images.Meanwhile, it must adapt to specialized scenarios including agricultural meteorological services and disaster emergency scheduling, guaranteeing efficient and synchronized command transmission.

Based on on-site investigation, AISP integrated professional equipment to deliver a customized solution that precisely aligns with the characteristics of meteorological operations.

Professional Sound Reinforcement, Laying a Solid Foundation for Audio Transmission

AISP adopts the design concept of “zone-based adaptation, system linkage” to equip conference rooms of different sizes with a full set of sound reinforcement equipment, achieving uniform sound field coverage and accurate sound quality reproduction.

The digital mixing console, audio processor and feedback suppressor work in coordination to eliminate howling and echo, ensuring clear transmission of meteorological data and forecast conclusions.Six professional conference speakers paired with three power amplifiers realize full-coverage sound without dead zones, solving uneven audio perception and adapting to various conference scenarios.

The hand-in-hand conference system (1 chairman unit + 5 delegate units) enables orderly management of speaking rights.Two anti-interference wireless microphones meet the needs of mobile speaking, suitable for training, temporary scheduling and other scenarios.

Intelligent Central Control, Improving Office Efficiency

Based on the central control host, an intelligent management platform is built to integrate full-scenario equipment, greatly reducing operation difficulty and meeting the high-efficiency requirements of meteorological operations.

The 8×8 ultra-high-definition HDMI seamless switcher realizes zero-delay switching of multiple signal sources, ensuring clear display of meteorological charts and satellite cloud images.Equipped with 4 infrared emitters, it supports preset scene modes, enabling one-key operation of equipment startup/shutdown and signal switching without professional personnel on duty.

The multi-function power sequencer controls power supply in a preset sequence, avoids surge current impact, protects equipment, extends service life, and builds a solid defense line for system stability

Full-Scenario Coverage, Balancing Practicality and Scalability

AISP's solution precisely meets the full-scenario operation demands of the new venue, establishing an audio-visual support system featuring efficient indoor conference discussion and timely outdoor early warning.

It strengthens core audio-video capabilities for indoor conference rooms, while supporting a professional outdoor broadcast system that integrates daily ambient sound, official announcements, and emergency meteorological early warnings.

Centered on a broadcast preamplifier and 16-zone matrix distributor, the system is equipped with 13 weather-resistant outdoor lawn speakers, a DVD player, and desktop microphones, enabling precise multi-zone control, multi-source audio playback, and manual announcements in emergencies.It ensures uniform sound coverage, clear audio quality, and excellent weather resistance and anti-interference performance.

Equipped with a power sequencer that coordinates with the indoor system, it accurately controls power on/off in a preset sequence, effectively avoiding surge current impact and ensuring safe and stable operation of the entire system.Adopting a modular design with sufficient reserved expansion ports, the system flexibly supports both current operations and future upgrades of the smart meteorological station.

Since the new venue was put into use, the system has provided stable and effective support for agricultural meteorology seminars, severe convective weather emergency conferences, and grassroots meteorological work.With reliable performance and excellent user experience, it has earned high recognition from the station's staff.

Focused on scenario-oriented solutions, AISP delivers high-quality integrated audio-video solutions for various institutions.In the future, AISP will continue to deepen technological innovation and empower high-quality development across all industries with precise and professional solutions.
