Installation and Operational Challenges​

Modern stations, no matter whether Metro or Main Line, Underground or Overground, all play multiple roles, and are of strategic importance. Stations pose considerable security, installation and operational challenges, while passenger demand is expected to double over the next ten years. The need for reliable safety and security systems at rail stations is higher than ever.

Focus on Rail and Rail Safety

Rail is a core market for ASL, and our products are designed around the world’s most stringent safety standards; EN 54, CSA and UL, as well as local pre-approvals such as Network Rail’s PADS in the UK and TransQ across Scandinavia. ASL’s focus on rail means that we produce sector-specific products, for a perfect fit with the requirements. These include dynamic volume control, platform microphones, and radio microphone systems.

Long Line Solutions

ASL’s Public Address and Voice Alarm equipment is designed for remote operation over long distances. ASL’s PAVA products deliver the performance you need, in the most remote stations, with the most demanding environments, and with remote system monitoring and control. ASL’s iVENCS Long Line Public Address (LLPA) and Customer Information System (CIS / PIS) solutions enable rail operators to manage an entire network’s PA or CIS requirements simultaneously, across multiple lines, stations and interchanges.

Challenges

With more than 25 years experience of designing and developing Public Address and Voice Alarm products for the transportation market, ASL offers peace of mind. You can rely on ASL solutions to work, and to continue working, throughout the life of the system.

Our PAVA systems will deliver the message to where it needs to be heard, when it needs to be heard.

ASL’s DANS01 dynamic ambient noise sensor enables the  PA volume level to be automatically adjusted in real time. These noise sensors feed audio from their PA zone back to the ASL router, where the DSP digital signal processor separates any broadcast audio from the ambient noise. Thus, the volume can be controlled in response to ambient noise, even during announcements.

The DANS noise sensors are ideal for use on railway platforms, to keep the audio at a comfortable level and intelligible, while also addressing any noise abatement issues, even if the noise level varies widely during a broadcast.

ASL understands that PA migration come with risks and often happen in stages. ASL systems can readily work with existing third-party PA systems either during a changeover phase or on a permanent basis to manage risk in a predictable way.

The ASL equipment's analogue audio inputs as well as IP LLPA control enables easy migration even when installing an entire new ASL LLPA system, with an iVENCS control front end.

Proven reliability: With ASL's first generation systems still installed and running. Long, reliable, product life means lower ownership costs and low whole life costs.

Efficient power supplies and amplifiers reduces lifetime energy usage, and reduces equipment room cooling requirements.

Hot-swappable amplifier cards means less need for costly night time service visits.

ASL's professional audio PAVA systems provide high quality background music, to ensure a relaxing and consistent customer experience, as well as providing the highest standards of station safety.

Local control of music source and volume allows tenanted areas to create their own ambience. without the need for a separate system, and without loss of control to the station staff.

Interfacing to Active Array Speakers is simple, including speaker monitoring. End to end audio path monitoring is facilitated by the use of specialist audio monitoring tones, built-in to the ASL routers.

To secure the PAVA system and to ensure uninterrupted operation: ASL’s solution supports full encryption and authentication of control and audio data, including 2Factor authentication for tools and configuration management.

ASL’s iVENCS Control System provides powerful Long Line PA controls, and can be integrated with any train control or signalling system, or with Darwin.

For integrated PA and Customer Information Display messaging, simply add the display module to a LLPA system, or add other modules such as CCTV, Help Points or SCADA to produce a whole-line control system.

Sector-Specific Products

ASL combines close liaison with our customers and end users, technological innovation, and the comprehensive railway knowledge of our experienced team to set new standards with our industry specific products. A few key examples are referenced below. All of which were designed in close collaboration with the UK’s Network Rail and Transport for London (TfL).

Radio Microphones

ASL’s RPA01 handheld Radio Microphone Transmitters and the supporting receivers, chargers, and radio antennae are in constant use across the London Underground network. These radio microphones were developed in conjunction with TfL to meet the specific requirements of London Underground.

The RPA radio microphone system demonstrates ASL’s ability to design specific products for a customer’s need.

Induction Loop Panels

ASL’s ILP02 Induction Loop Panel delivers easily-heard announcements for people with hearing impediments, through their hearing aids or cochlear implants. The ILP02 was designed with TfL to provide easy to install and reliable local induction loop coverage at station and platform information boards, and are driven remotely by standard ASL 100V PAVA amplifiers. The loop panels are mounted above the information boards, visually integrated with the board frames, or are located nearby on the ceiling.

These loops are in wide-scale use across the London Underground.

 

Vandal-Resistant Microphones

ASL’s range of SAP rail-specific platform microphones are housed in IP65 vandal-resistant, lockable, stainless-steel wall-mounting boxes, making them ideal for public areas. The SAP02 is a single-zone microphone, while the SAP03 provides ten function and zone selection buttons. The SAP02 can also house an ASL RMR02 Radio Microphone Receiver, to enable radio microphone announcements to be made in addition to the SAP’s standard fist microphone announcements. For emergency use there is also a red coloured variant of this microphone, the EAP01.
These microphones are in wide-scale use across the London Underground network.

iVENCS

The iVENCS Control Software is a truly open and intuitive integrated management platform

iVENCS - LLPA, Long Line CIS, and Station or Line Management System

ASL’s enhanced iVENCS Line and Station Management System provides integrated distributed control

The iVENCS Control System has recently received an entire technology and GUI upgrade, consolidating its place at the forefront of station and line management.

The iVENCS Line and Station Management System (LSMS) provides the ability to control and monitor all aspects of Line, Depot, Station and On-Train systems, with full integration with your Train Control and Signalling System. The LSMS can provide powerful OCC Operational Control Centre and local station workstations, plus Line Overview Video Walls which combine alarm and status reporting with CCTV views, and can also be combined with the signalling system’s line map. Integrating the iVENCS LSMS with your Train and Signalling Control system enables the trains to be managed at the required Safety Integrity Level, while iVENCS provides the operators at the OCC and at the stations with powerful and simple to use telecoms and security controls.

The award-winning and unique true 3D GUI can show a whole line map with drill down to accurate, fully scaled models of individual stations. The model’s pan, tilt, rotate and zoom controls allow the user to move the viewpoint at will, to any part of the 3D station models and to any floor, with seamless viewing from any position. This avoids other system’s need to split the station map GUI into multiple small 2D maps and false-3D building plans, requiring the operators to switch between many different maps in order to operate the station’s equipment.

Key Features:

  • Award-winning 3D or traditional 2D GUI
  • System schematics and dedicated subsystem controls
  • Consistent and simple to use functionality, for multiple systems
  • Ability to provide advertising content onto displays
  • Remote Condition Monitoring
  • Distributed processing with multi-site redundancy
  • Modular system architecture; easily expandable
  • Cross-platform support
  • No ongoing license cost

Line and station operators need to monitor an ever-increasing number of subsystems, from fire detection to CCTV, PA to information displays, access control to intruder detection, and far more. ASL’s award-winning iVENCS Control System empowers both managers and staff to simultaneously control a multitude of systems. Via the intuitive 3D user interface, operators can keep a constant eye on the public and on the status of equipment around the station or along an entire line and on the trains. The operators are able to remotely control devices, and be alerted to any faults and devices that are in need of investigation.

iVENCS makes public and staff communications easier to manage, through synchronised PA and CIS display messaging, auto-scheduled announcements, intelligent message builders and multilingual messaging capability. iVENCS can give complete control of passenger and staff information boards and advertising displays.
