All our projects have a flexible guarantee period tailored to the specific features and needs of each customer, wherever required, achieving/guaranteeing safety at all times as well as the highest availability and reliability rates.
SAM is CAF Signalling’s solution for a comprehensive trackside signalling system maintenance.
SAM allows the gathering of diagnosis information from all kind of trackside signalling products (interlockings, ERTMS, etc.) aiming to show real time status of the equipment and field elements. SAM is able to display raw and processed information using various layouts and formats to ease maintenance tasks.
TECHNICAL FEATURES
Architecture
The SAM’s suit of products have been designed to offer different functionalities depending on the project needs.
- SCOM: In charge of acquisition and storage of diagnosis information directly from signalling products, this CENELEC SIL2 product allows a redundant active/active architecture optionally. SAM and JRU need SCOM for raw data gathering in a lower level.
- Local & Central SAM: After receiving data from the different trackside signalling products through SCOM, these products show relevant information for the maintenance of those systems to the final user.
- JRU: This CENELEC SIL2 developed product implements specific juridical recording functionalities.
Layouts
Local & Central SAM are able to show relevant information in different aggregation levels and formats: dashboards, communication networks, operational synoptic, several housing perspectives, etc.
Playback
Local & Central SAM handle the information in a way that allow the playback of past events using the operational synoptic layout. Thus, the final user is capable to analyse the sequence of alarms and events occurred in a certain zone of the line.
Alarm management
This feature presents real time alarms, or gives the possibility to search for a concrete alarm or event occurred in the past. Generation of alarm and event statistics is possible too in a graphical manner.
Reports
SAM is able to generate reports like: active alarms, filtered list of events, status of key variables of the system, executed maintenance commands, list of existing software version and data configuration version in supervised equipment, etc.
Maintenance commands & services
Some maintenance-related actions are possible to be commanded from SAM HMI by the user, like: operational counters management, movement of switches and points due to maintenance activities in coordination with control centre, signal normalization after maintenance intervention, download of JRU, etc.
System master clock
Optionally, the SCOM can behave as system master clock synchronizing all the products under supervision using NTP protocols.
Remote access
Once the SAM is installed, a remote connexion using a light client from any other PC in the network to check maintenance information is possible.
Users & profile management
The access to the SAM application is controlled by security mechanisms, able to manage users and profile types. This way, access to the different information areas and functionalities depending on the user and its profile is ensured.
Project specific data prep
A project specific customization layer allows SAM to be flexible and be adapted to every client and project specificities. This specific configuration is developed and tested in laboratory before commissioning.
BENEFITS & ADVANTAGES
Comprehensive maintenance solution
SAM gathers and organizes maintenance information from all CAF Signalling products in one single homogeneous application. The harmonized look and fell and its user-friendly interface allow an easy and short learning process for the maintenance user.
Scalability & adaptability
SAM’s software is designed to allow an easy extension of the number and type of supervised products, not requiring software configuration changes when an already supervised product increases the number of elements of a certain type (eg. IXL sending new signals information).
From corrective to condition-based maintenance
Corrective, predictive and condition-based maintenance functionalities are implemented in the SAM. These functions allow a better coordination of maintenance actions, and the optimization of field elements’ life cycle.
