Cargo Control System Composition

Our cargo control system adopts an advanced modular design. On one hand, the system can operate independently; on the other hand, it can function as a subsystem of the ship-wide monitoring and alarm system. The cargo control system is primarily composed of the following four subsystems:

·Tank Level Telemetry System
·Valve Remote Control System
·Cargo Hold Water Ingress Alarm System
·Independent High-Level and Overfill Alarm System

Internal communication between the subsystems is highly efficient. Each subsystem can operate independently, and clients can select the specific subsystems according to their requirements.

Advantages of Our Cargo Control System

Uses a general-purpose programmable logic controller (PLC) as the control and signal acquisition module, maximizing system stability and safety.

Distributed data acquisition with centralized control ensures accurate and convenient collection and management of various signals.

Compatible with multiple standard bus protocols, such as GeniusBus, ModBus, ProfiBus, greatly expanding system applicability.

Advanced modular packaged design allows subsystems to operate independently while also enabling seamless interconnection and coordinated operation, supporting customized configurations to meet specific client requirements.

Multiple human–machine interfaces (HMI), including IPC, touchscreen panels, and MIMIC boards, ensure operators can easily and quickly access information and control the system.

Built with high-quality hardware and software, providing safe, reliable, and high-performance operation, with unified management and comprehensive global maintenance support.

Detailed Overview of the Tank Level Telemetry System

The Tank Level Telemetry System monitors and alarms for tank liquid levels, pressures, temperatures, and draft at the four corners of the vessel. All signals are collected through Remote I/O modules installed in distributed acquisition boxes, ensuring signal accuracy. The Remote I/O modules communicate via bus with the PLC master station installed at the cargo control console, transmitting the collected signals to the PLC CPU module. The CPU processes the data and sends control signals back to the Remote I/O modules to implement remote telemetry.

The human–machine interface installed on the industrial PC (IPC) allows operators to access real-time monitoring data and handle alarm information, including storage, printing, and backup.
