The ballast water system is critical for maintaining the stability and balance of ocean-going cargo vessels. This solution employs an ARM Edge Controller to automate ballast cabin control, ensuring optimal vessel trim and stability under varying load conditions.
The proposed solution utilizes the following components:
ARMxy Main Controller (Marine-Grade): A robust, marine-certified ARM Edge Controller designed to withstand harsh maritime environments.
Y-AI Board: Analog input board for monitoring draft depth and cabin liquid levels.
X-DO Board: Digital output board for controlling ballast pumps and valves.
Draft Sensor: Measures vessel draft depth with a 0-20mA signal corresponding to 0-15 meters. The Y-AI board converts this analog signal to digital data for processing.
Cabin Liquid Level Sensor: Utilizes ultrasonic sensors with a 4-20mA output to monitor ballast cabin liquid levels, ensuring precise volume measurements.
The ARMxy Edge Controller processes real-time data from the Y-AI board, including vessel load and draft measurements.
Based on the cargo load, the system calculates an optimal trim scheme to maintain vessel stability, adhering to maritime safety standards.
The control logic is implemented using OpenPLC, an open-source programmable logic controller software tailored for industrial automation.
OpenPLC processes inputs from the Y-AI board and executes control algorithms to adjust ballast pump and valve operations via the X-DO board.
The logic ensures dynamic adjustment of ballast water distribution to achieve the desired trim and stability.
The ARMxy Edge Controller interfaces with a satellite communication module to transmit operational reports to the shipping company’s headquarters.
Reports include real-time data on draft depth, cabin liquid levels, pump/valve status, and trim calculations.
Data is securely transmitted in a standardized format (e.g., JSON or XML) for compatibility with fleet management systems.
Remote Monitoring: The ship company’s headquarters can remotely monitor the real-time status of the global fleet, enabling proactive decision-making and maintenance scheduling.
Automation and Precision: Automated trim calculations reduce human error and ensure optimal vessel stability, improving fuel efficiency and safety.
Scalability: The modular design of the ARMxy Edge Controller, Y-AI, and X-DO boards allows easy integration with additional sensors or systems as needed.
Robustness: Marine-grade components ensure reliable operation in harsh environmental conditions, including high humidity, temperature variations, and vibrations.
The ARM Edge Controller for the ballast water treatment system provides a reliable, automated and scalable solution for ballast tank management for ocean-going cargo ships. By leveraging real-time data acquisition, OpenPLC control logic and satellite communications, the system improves ship stability, operational efficiency and remote fleet management capabilities.
