The Solution Experience Zone at PCI Customer Experience Center integrates various functionalities. It includes Digital Airport Solutions, Parade Solutions, Smart Guidance Solutions, and also offers the opportunity to experience various branded speakers represented by PCI. Today, let's start by exploring the Digital Airport Solution.

The robust and stable performance of the Q-SYS ecosystem forms the foundation that meets the complex demands of airport environments: handling multiple audio sources, numerous audio output channels, diverse business broadcasting formats, high concurrency demands, complex priority management, varied user departments, and dispersed user operation areas. This capability distinguishes PCI from its competitors and positions it as a partner for Beijing Daxing International Airport.

When I expressed interest in experiencing the Digital Airport Solution, the guide handed me an iPad, leaving me confused as to how to navigate such a complex system.

However, the interface, though entirely in Chinese, was clear and intuitive. Even as a novice, I could understand the functions through the button names. The interface also allowed customization of page layouts based on the airport's specific requirements, enabling control over various broadcast functions such as automatic broadcast, manual broadcast, background music, and emergency broadcasts.

The automatic broadcast function in the experience area plays pre-recorded audio content in designated areas at preset times, with customizable loop rules. Using the manual broadcast function is as simple as inputting the specific area code at the calling station or tapping the designated area on a mobile device for immediate voice broadcasting.

Additionally, the background music function not only plays local audio but also integrates with priority management. When a high-priority audio signal is detected, the background music automatically pauses and resumes after the signal ends.

During my exploration of the broadcast functions, an emergency alarm startled me. It turned out the guide was demonstrating the emergency broadcast feature, piquing my curiosity about the intricacies of such overlapping and complex functionalities.

The guide attributed the system's capabilities to the Q-SYS ecosystem, with the Core processor serving as its nucleus. All audio signal processing, routing, and control signals within the system occur here. The Core processor utilizes advanced 64-bit multi-core central processing units for audio signal processing, enabling it to handle the intricate demands of airport environments. A single processor can support 512 simultaneous input and output channels, arranging all channel priorities according to the configured settings through the priority broadcast management feature.

Moreover, post-routing by the Core processor's signal routing function, all audio signals can be freely selected for playback in specific areas, supporting simultaneous broadcast on 512 channels, preventing congestion during peak periods. The system's automatic voice broadcast employs dynamic audio channel routing, optimizing channel management to ensure each channel operates ideally and timely scheduled broadcasts are accurately deployed in designated areas.

I was intrigued; could a single processor suffice for such a vast airport? The guide explained that apart from supporting single-machine management, the strength of the Q-SYS ecosystem lies in its support for communication between multiple mainframes and systems, allowing for the construction of composite systems. This capability enables the system to handle an almost infinite number of channels, as long as an equivalent number of Core processors are employed, ensuring comprehensive coverage irrespective of the environment's size.

After the explanation, I discovered that the mobile terminal allows real-time monitoring of all device operations. Surprisingly, one processor had 'failed', but the guide assured me not to worry. In the event of one processor failure, another backup processor automatically takes over the system.

Moreover, to prevent network failures from paralyzing the system, adding switches and network cables allows for easy network backup. If the primary network fails, the Q-SYS system instantly switches to the backup network.

In critical locations, designers have the option to create backups for input/output interface boxes.

Furthermore, to ensure uninterrupted operation, the Q-SYS system supports comprehensive backups, including network, system processing hosts, input/output interface boxes, and amplifiers. Even simultaneous equipment and network failures won't disrupt system operation.

The Q-SYS ecosystem can be equipped with amplifier switchover devices, allowing switching between 8 main amplifiers and 1 backup amplifier using a single amplifier, complemented by automatic fault detection, alarms, and automatic switching to the backup device in conjunction with the Core processor.

Simultaneously, the amplifiers can monitor the impedance of each circuit speaker in real-time. If an abnormality is detected, the amplifier sends an alert to the Q-SYS ecosystem, specifying the problematic circuit. All alerts, fault types, and specific fault locations are promptly displayed and compiled into a fault detection list on the system management server, which can also be printed if needed.

To ensure comfortable and clear broadcast volume for passengers, the Q-SYS system features automatic gain control for ambient noise adjustment in current playback areas. Coupled with the powerful digital audio processing capabilities of the Core processor, it maintains comfortable and clear broadcast volume levels.

Upon seeing an aerial view of Beijing Daxing International Airport, I wondered how staff would manage equipment failures in such a vast area without wasting time traveling between terminals. The guide explained that for easy equipment management, the Q-SYS ecosystem employs a centralized management and decentralized control architecture based on three-tier Ethernet technology. All system devices are directly connected to the audio system's dedicated gigabit Ethernet via interfaces, ensuring low latency, high-quality audio, and centralized device management. Additionally, the system supports real-time network monitoring for staff to track device operations.

From the Digital Airport Solution manual, I learned that the system, based on Ethernet architecture, supports mainstream network audio transmission protocols like CobraNet, Dante, AVB, and LUA scripting language. This design ensures high scalability and compatibility for future IT functionalities and platforms. The system exhibits high scalability in terms of capacity, communication, processing capabilities, and system functionality. The Q-SYS ecosystem utilizes its diverse audio interfaces, control interfaces, and flexible programming to simplify and ensure reliable integration processes. It allows for low-cost product upgrades, replacements, functional expansions, adjustments, and renovations based on future usage requirements.

The Q-SYS system's powerful and stable performance is pivotal in meeting numerous requirements in airport environments, including multiple audio sources, numerous audio output channels, various business broadcasting formats, high concurrency demands, complex priority management, diverse user departments, dispersed user operation areas, complex engineering interfaces, and high stability and functionality expectations for broadcast systems. This distinction has propelled PCI above numerous competitors, making it a partner for Beijing Daxing International Airport.
