ALSTOM N897092520B N897092057Y TRENO N897092500E Control Module

Equipped with an industrial-grade processor, supporting real-time data collection, logical operation, and control command generation, suitable for dynamic adjustment of train traction/braking systems.

Capable of processing sensor inputs (such as speed, current, voltage signals) and generating precise control strategies through algorithms to ensure stable system operation.

Equipped with high-precision analog input channels (such as 4-20mA, 0-10V) for collecting motor parameters, pressure sensor signals, etc.; digital input/output channels (opto-isolated) for switch signal control.

Supports PWM (Pulse Width Modulation) output, enabling precise adjustment of parameters for actuators such as motor speed and valve opening.

Vibration and electromagnetic interference resistant (complying with EN 50155 rail transit standards), adapting to the harsh requirements of vehicle-mounted environments (such as temperature fluctuations and mechanical vibrations).

Built-in watchdog timer and fault self-diagnosis mechanism to ensure safe system response (such as automatic reset or fault reporting) in case of abnormalities.

Supports multiple industrial communication protocols, such as MVB (Multifunction Vehicle Bus), EtherNet/IP, Modbus, etc., enabling real-time data interaction with train network systems (TCMS) or upper computers.

Features data caching and transmission priority management to ensure communication stability in high-real-time scenarios.

Adopts standardized interface design, enabling seamless integration with other ALSTOM modules (such as N897092057Y), and supports system function expansion (such as adding communication interfaces or control channels).

Collects external signals (such as vehicle speed sensor and traction motor current signals) through analog/digital input channels, and stores analog signals in the cache after A/D conversion to digital quantities.

The internal processor filters, calibrates, and performs logical operations (such as motor status judgment and fault detection) on the signals at a preset frequency (such as 10kHz).

Generates control strategies (such as traction/braking torque adjustment) based on the collected data and upper computer commands, drives relays or transistors through digital output channels, or sends adjustment signals (such as PWM motor control) through analog output channels.

Supports closed-loop control: after outputting commands, monitors the status of actuators (such as motor speed feedback) through feedback channels, and real-time corrects control parameters to ensure accuracy.

As a node in the train network (such as MVB), encapsulates data frames through the protocol stack to interact information with the main control unit (VCU) and other modules (such as converter control units).

Receives control commands (such as start/stop commands) from the upper system, and uploads device status, fault codes, and other data to the monitoring system.

The power supply part adopts EMI filtering and isolation design to prevent voltage fluctuations; signal channels use magnetic isolation or opto-isolation to reduce electromagnetic interference.

Built-in fault diagnosis module real-time monitors chip temperature, voltage abnormalities, etc., reports faults through LED indicators or communication interfaces (such as code "E01" indicating communication interruption), and triggers protection mechanisms (such as cutting off output) when necessary.
