Subway Line Upgrade

Infrastructure Control and Monitoring System

Altus’ Engineering team was contracted to develop and implement a new supervision system for seven stations connected to the South Line of Companhia Paulista de Trens Metropolitanos (CPTM), fully integrated into the metro network of the city of São Paulo in Brazil.

Control System for Itaquera and Belém Yards

The Supervision System, designed with redundant RTUs to ensure high availability, was implemented to manage and monitor critical subsystems at each station on the South Line of Companhia Paulista de Trens Metropolitanos.

The solution enables real-time control and supervision of lighting systems, escalators, fire pumps, and main circuit breakers, ensuring operational continuity, rapid fault detection, and enhanced passenger safety. The redundant architecture minimizes downtime and guarantees secure communication between field devices and the central supervision environment.

The stations covered by the automation project include: Socorro, Granja Julieta, Morumbi, Berrini, Vila Olímpia, Cidade Jardim, Hebraica–Rebouças (formerly Eusébio Matoso).

With centralized monitoring and robust system redundancy, the project significantly improved reliability, safety, and operational efficiency across the South Line corridor.

The system integrates with other panels using protocols such as MODBUS and SPEC 6201, the latter designed specifically for communication with the Fire Panel. Communication via MODBUS and SPEC 6201 enables monitoring and operational control of the General Distribution Board (QGD), pumps, elevators, and fire systems.

Each station is equipped with a Monitoring System (supervisory stations) that communicates with the redundant PLCs over an Ethernet network. This redundancy ensures comprehensive control and command across all system points.
