smartVES

Flexible topology for large, urban stations

smartVES is a network-based public address system utilizing TCP/IP technology, compliant with railway standards (especially regarding EMC) and fully EN54 certified.

A key feature of the system is intelligent real-time sound adaptation, ensuring high speech intelligibility even in significant noise. The system integrates with passenger information systems, offering automatic announcements and remote management. Its primary task is to convey crucial voice information to travelers regarding safety, timetables, railway traffic, and carrier services.

Certified compliant with EN 54-16, EN 54-4

Tested for compliance with EMC standards in a railway environment

Networked Public Address System using TCP/IP technology

Remote configuration and monitoring capability, without the need for an on-site visit

Automatic volume and sound timbre adjustment function based on real-time noise sensor readings

Modular design minimizing the effects of failure

Ability to integrate with third-party systems in the digital domain using IP protocols: IP telephony, intercom systems, passenger information systems, visualization and management systems (PSIM, BMS, SCADA)

Intercom System

Reliable two-way communication at railway stations

The Intercom System is an advanced tool for two-way voice communication, based on the IP protocol.

It ensures seamless information exchange in key locations such as stations and platforms. Thanks to advanced digital sound processing – including noise reduction, echo cancellation, and automatic volume control – the system guarantees high speech intelligibility even in exceptionally noisy environments. The robust design and durable casing of the devices ensure reliable operation in harsh environmental conditions.

The system is characterized by easy integration with PA and other security systems, enabling comprehensive facility management, efficient handling of emergency calls, and continuous monitoring. Additionally, all events and conversations are recorded, providing valuable support for security analysis and crisis management.

smartVES Central Unit

The central control unit SMART-CU11 is a key functional element of the system. The system is scaled by the required number of control units, which communicate with each other via a TCP/IP network, ensuring flexibility in extensive installations.

Each location requires at least one smart-CU11 unit, equipped with a service panel featuring an intuitive touchscreen. The SMART-CU11 performs many key functions: it acts as a digital announcement player, an audio matrix for signal routing management, an amplifier control interface, a fire alarm interface, and an advanced DSP (Digital Signal Processor). Furthermore, the smart-CU11 unit offers integration with external systems, utilizing both analog and digital interfaces.

Two-way communication

The Intercom System is a tool for two-way communication between passengers and services responsible for safety, assistance, and order.

It consists of communication modules (intercoms), equipped with a microphone, speaker, and function buttons, installed at stations and passenger stops. All transmissions within the system occur via the IP network. Operators, located in the control center, receive calls from intercoms and take appropriate actions. The server additionally enables intercom integration with third-party systems, particularly PSIM and CCTV, ensuring comprehensive supervision and event management.

smartVES Intelligent Algorithms

STTA
Speech Signal Time Transposition
Algorithm

A function for adjusting the pace of announcements. The system automatically slows down announcements made by operators, which increases their intelligibility.

AF
Adaptive Filtration
Algorithm

A function for automatic volume and sound timbre adjustment based on real-time noise sensor readings. The system analyzes the noise spectrum and reacts to its changes by applying narrowband filters. This ensures that announcements remain intelligible, even in noisy conditions.

Intercom System Intelligent Algorithms

Noise
Reduction

Effectively eliminates unwanted background noise (e.g., street traffic, train noise) from the speech signal. Increases communication clarity in acoustically challenging locations.

Echo
Cancellation

Detects and eliminates acoustic echo during two-way communication. Ensures natural and fluid conversations, improving user comfort.

Automatic
Volume Control

Dynamically adjusts the audio signal volume to prevailing acoustic conditions. Maintains optimal speech intelligibility, regardless of changing environments.

Integration of voice communication systems in railways

Intelligent and Integrated PA and Intercom Systems

An individual approach to design, based on specialized engineering knowledge, guarantees the system's adaptation to specific facility and technical requirements.

Public Address System
Integration

The public address system serves as a tool for conveying information to passengers regarding train timetables. In the case of extensive stations, this system can simultaneously function as a PAVA.

Therefore, to ensure comprehensive functionality and safety, the system must be integrated, in particular, with:

Passenger Information System
Fire Alarm System
PSIM System

Intercom System
Integration

The intercom system enables two-way communication between passengers and railway personnel. This functionality allows operators to take action in response to reports and emergency situations.

For this purpose, the intercom system connects with security systems such as:
