Quality is dedicated to the future

Tsunami buoy

A tsunami is called a "shallow water wave" and its wavelength can reach hundreds of kilometers, which is much larger than the water depth. In the deep water area, the existence of the "bottom" can be felt, and it is an ideal low-pass filter. Tsunamis, tides and other long-period fluctuations are monitored by simply measuring pressure at a fixed point on the ocean floor. Once a tsunami occurs, the tsunami buoy can be triggered automatically or by manual instruction (satellite transmission) for high-density sampling and data transmission. The system includes a seabed-based pressure gauge (with acoustic release and battery unit), surface mooring system (mainly used for hydroacoustic communication and satellite data transmission). The real-time water level data in the early warning responsibility area will be integrated into the tsunami buoy system, which can provide functions and management similar to tide level stations.

Communication relay buoy

The communication relay buoy focuses on solving the problem that when the distance from the underwater terminal to the shore base station in the ocean network is too far, a buoy relay station can be set up to forward the signal sent by the previous station to the next station as it is, extending the communication distance and maintaining better communication quality.

Emergency warning AIS buoys for inland rivers

Equipped with an AIS positioning transmitter and warning signal lights, it can be used to locate and mark obstacles (no-navigation areas), and regularly send messages to the AIS shipboard terminals of adjacent sailing ships and the information platform of the port and shipping management department, so that sailing ships can be effectively avoided. Provides safety information for a variety of water activities.

Dynamic Monitoring System of the Ship

The ship supervision system is composed of the onboard monitoring terminal and system monitoring platform software. The onboard monitoring terminal receives global navigation satellite system (GNSS) signals to form ship position information, and sends it to the system monitoring platform regularly through wireless communication (Beidou + public network). The system monitoring platform can form information such as ship position, trajectory, and entry and exit visa records through data reception, processing, and integration. There will be an alarm when there is an abnormality, which can be displayed on the system monitoring platform and the mobile phone of the administrator, thereby providing a basis for scientific and efficient management of law enforcement.

VHF Communication System

The VHF communication system adopts the digital switching control equipment as the shore-based dispatch communication platform for port communication, so it can be used for maritime distress search and rescue wireless communication for ships in coastal waters, including dispatch, dialogue, and alarm functions. In addition, the communication system can also provide watercraft traffic safety and emergency command for inland waterways and maritime affairs departments. The system fully complies with the industry standards and specifications of related technologies and equipment formulated by the national transportation department.
