Samarco Mining

Control System for Access to the Breakwater Area

The Samarco Mining facility, located in Ubu, Espírito Santo, chose Altus technology to implement a storm surge safety system.

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

Remote Access

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

A arquitetura implementada utiliza dois CLPs XP340, modelo mais avançado da Série XP, para calcular o risco de ressaca e realizar o acionamento dos semáforos que indicam o perigo de acesso ao local. A solução desenvolvida conta com um sistema web baseado em NODE-Red para fazer consultas do tipo HTTP ao servidor que contém os dados enviados pelos sensores embarcados na boia instrumentada em alto mar, utilizada para coletar informações sobre o clima e as variáveis que precedem o momento distúrbio do oceano. O sistema, então, envia estes dados para o controlador através do protocolo de comunicação OPC UA.

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.
