Los sistemas DAQ imc funcionan de forma descentralizada y en red, capturando todos los datos de medición de forma sincrónica. El análisis de datos integrado en tiempo real permite la visualización, el procesamiento, la vinculación y el análisis inmediatos de los datos. Este enfoque proporciona perspectivas e información significativa que van más allá de las simples mediciones directas. El análisis en tiempo real no se reserva para evaluaciones posteriores de los datos, sino que se realiza simultáneamente, está disponible junto con los datos de medición primarios y es gestionado de forma coherente por el sistema de medición. Esto permite combinar datos de todas las áreas del tren, como canales analógicos con datos de buses de campo internos del tren. Esta configuración permite disponer de una visión general del estado operativo del tren, de las unidades funcionales o de componentes específicos durante las pruebas, como una marcha de prueba. La "multimonitorización en directo" permite además una monitorización en tiempo real rápida, segura y eficaz, permitiendo que varias estaciones de monitorización (o PC) accedan simultáneamente a todos los datos, los visualicen y añadan comentarios de texto, audio o voz en directo.

Estas piezas de metainformación se ajustan con precisión a sus correspondientes canales de medición, se almacenan y se combinan con canales de vídeo para formar un sistema integrado de canales analógicos, digitales, virtuales (computados), de bus de campo y multimedia. Esta completa "reserva" de información de medición está disponible para la gestión avanzada del almacenamiento, la gestión de bases de datos y el análisis posterior mediante imc FAMOS u otras herramientas de terceros. Con esta configuración, los expertos pueden obtener resultados precisos basados en datos para el desarrollo y las pruebas de diversos componentes, como frenos, suspensión o sistemas de propulsión.

With more than 30 years of field experience and hundreds of successful rail projects worldwide, imc Test & Measurement offers proven DAQ platforms for distributed rail testing—from prototype evaluation to certification.

Distributed imc CRONOSflex and imc ARGUSfit systems are networked via high-speed, real-time buses:

imc CRONOSflex: based on EtherCAT, a deterministic fieldbus for high-precision synchronization and fast data exchange over large channel counts. 

imc ARGUSfit: uses fiber-optic links—immune to interference and suitable for long distances.

All imc DAQ systems support multiple synchronization methods:

• Cable sync for compact setups
• GPS or IRIG-B for long-range applications
• PTP (Precision Time Protocol) over Ethernet for distributed networks

A proprietary imc process guarantees sample-accurate timing across more than 1,000 channels distributed over multiple cars.

CRONOSflex modules support Power-over-Ethernet, carrying power, data, and sync on one line. For larger networks, separate power modules can be integrated wherever needed—keeping installation clean and scalable.

imc systems are designed for real-world rail conditions: shock- and vibration-proof, with optional extended temperature range  from –40 °C to +85 °C (–40 °F to +185 °F ) and high EMC immunity. The imc PROTECT series is built for the toughest test environments.

With imc CRONOSflex and imc ARGUSfit, imc offers two fully modular and distributed DAQ systems that can be flexibly combined to cover any rail testing requirement. Both platforms follow the same principle: measurement modules are positioned close to the sensors, digitizing signals right at the source and transmitting them synchronously across the train:

• imc CRONOSflex: A high-precision, modular DAQ system for large channel counts and demanding test programs. Ideal for certification, validation, and multi-car measurements, it supports EtherCAT networking, Power-over-Ethernet, and long-distance scalability.
• imc ARGUSfit: An ultra-compact, click-modular DAQ system designed for confined installation spaces such as underframes or interiors. Its fiber-optic link ensures interference-free operation and high data rates over extended distances.

For specialized measurement tasks, these systems can be seamlessly expanded with complementary imc solutions:

• imc BUSDAQ: A fieldbus data logger (CAN, MVB, Ethernet, etc.) that synchronizes perfectly with all imc DAQ platforms.
• imc Telemetry: For wireless signal acquisition from rotating components such as wheelsets or brake discs, transmitting measurement data reliably to the imc DAQ system 

Together, these modular systems provide engineers with a flexible, distributed measurement architecture—scalable from individual subsystems to complete trains.

With imc STUDIO software, all distributed modules can be configured, controlled, and monitored from one interface—no matter where they sit in the train.

Engineers can:

• Visualize and monitor signals live
• Automate measurements and trigger on events
• Run first analyses during test runs
• Detect limit violations instantly

Seamless integration with imc FAMOS allows detailed post-processing, automated evaluation, and customized reporting.
From measurement to report—a continuous, efficient workflow for rail testing.

imc DAQ systems integrate easily into existing toolchains:

• Import of sensor lists, thresholds, and metadata
• Export to MATLAB®, Python®, or DIAdem™
• Standard formats (MDF4, CSV, HDF5) for universal data access
• Direct links to databases and network storage
