Samarco Mining

Control System for Access to the Breakwater Area

A unidade da Samarco Mineração, localizada na cidade de Ubu, no Espírito Santo, buscou nos produtos da Altus a tecnologia necessária para implementar um sistema de segurança contra ressacas marítimas, reforçando seu compromisso com a proteção da infraestrutura, dos colaboradores e do meio ambiente.

Storm Surge Safety System

A solução, criada pelo cliente em conjunto com a Luxvix, representante comercial da Altus no estado do Espirito Santo, controla o acesso à área do quebramar do porto. Ela utiliza dois controladores da Série XP, nossa linha de CLPs compactos e IoT-ready, para comunicar com a boia instrumentada, que fica em alto mar, e com os semáforos para indicação de ressaca.

O sistema desenvolvido é utilizado para controlar a entrada à área do quebra-mar do porto e sinalizar aos trabalhadores o risco de acesso ao local.

Safety

Control access to the breakwater area and warn workers about possible risks

Alert System

The Altus PLC evaluates storm surge risks and activates the traffic lights

Communication

A web-based system powered by NODE-Red makes HTTP requests to the server holding the data

Acesso remoto

The system is also connected to the Ubu Port IIoT Portal via the MQTT protocol

Comunicação rápida e estável para evitar desastres

Reliable communication to prevent disasters

The architecture relies on two XP340 PLCs, the most advanced model in the XP Series, to assess storm surge risks and activate the traffic lights that signal danger in the area. The solution includes a web-based system using NODE-Red to send HTTP requests to the server, which stores data collected by sensors on the instrumented buoy offshore. This buoy monitors weather conditions and other variables that indicate approaching ocean disturbances. The system then transmits the data to the controller via the OPC UA communication protocol.

Como funciona o sistema de segurança contra ressacas

How the storm surge safety system works

If wave heights exceed the pre-set threshold in the logic, the PLC turns on the red light, signaling that the area is at risk from a storm surge. If the PLC goes more than one hour without receiving new wave height data, the yellow light activates, warning of potential risk. If the wave height remains within safe limits, the green light allows access to the area.

The system is also connected to the Ubu Port IIoT Portal via MQTT, a widely used standard in IoT applications, allowing for remote monitoring and manual control of the traffic lights when necessary.
