Technical Communication Based on the experience of installing DPDT dynamic positioning dynamic track a trace system on three dredgers, the configuration of the power system is critical. In the initial design of the ship's plan, it is necessary to analyze the dynamic positioning capability according to the selected main propulsion CPP, rudder and bow thruster, and consider the marine environment and operation mode of the actual operation of dredging and digging S, and adjust the main propulsion CPP, rudder and stern side. The power of the pusher. It is believed that the DPDT dynamic positioning dynamic trajectory system will be more maturely used on dredgers, and through its powerful computational analysis capabilities, accurate mathematical models, and reasonable power configuration, it can make the crew from heavy operations. Relieve in the process, improve the accuracy and efficiency of the operation, effectively shorten the construction time, reduce the cost, and improve the competitiveness of dredgers participating in international dredging competition.

Compressed air is still used in almost all industry sectors, whether for driving, control, motion or transmission. For efficient machine processing, compressed air must be analyzed and monitored as thoroughly as possible and integrated into the control system in an optimal manner. The EtherCAT terminal box EP3744 is a compact, all-in-one solution for this application. This IP67-rated terminal box integrates compressed air measurement, EtherCAT connection and digital I/O, which can be used directly on the processing site and installed outside the electrical cabinet. In addition to the 6 digital inputs and 2 digital outputs, the EtherCAT terminal means that the EP3744 has 4 pressure inputs and integrates 6mm ampere fittings. The pressure is measured as the difference from the fifth pressure connection and is connected via a hose to a protective enclosure with IP 67 protection. The measured value is provided in the form of a 16-bit value that is transmitted to the controller in an electrically isolated manner. The measuring range is "1 bar (15 psi) with a resolution of 1 mbar per digit. These allow this stand-alone compact stand-alone unit to be used for direct measurement and monitoring of field pressure. On the one hand, the need to remove from the machining site to the control cabinet The long route and hose connection. On the other hand, frequent provisioning of the specified electrical isolation and pneumatic system isolation becomes extremely simple. The other advantages of the system's integrated solution are also the short response time. Because of the local measurement, only one A/ is used. The D converter implements an EtherCAT interface and other digital I/Os, so it can be integrated into the control system particularly efficiently. Detect and eliminate leaks to reduce energy consumption. In addition to control and regulation, analysis and diagnosis are also essential where pneumatic systems are used. For example, the operating pressure can be monitored using the EtherCAT terminal box EP3744, which increases the transparency of the device. Another important feature is to eliminate leaks, which can reduce the energy costs associated with generating compressed air. Distributed and system-integrated pressure measurement is also an ideal solution for detecting and determining leak locations. The EP3744 also makes the process flow smoother: for example, the vacuum required for the clamping process in a fully automated pick-and-place machine can be monitored without difficulty. For this purpose, the EtherCAT terminal box can be integrated into the compressed air supply system of the gripper with a simple joint (T-joint).
