Marine controller

By means of technical means, the ship’s location is monitored in real time, so as to realize remote real-time tracking of production safety and shipment schedule execution.

application

The realization of ship real-time monitoring has important commercial value. On the one hand, shipping companies, chartering companies and other ship operators can remotely monitor the real-time dynamics of ships, so as to understand the safety management of ships and the implementation of shipping schedules.

On the other hand, the port management department can realize all the monitoring of the ships in the port area, so as to better arrange the operation plan and ensure the safety of the port area.

In addition, ship agency companies, spare material supply companies and other ancillary industries of ship services can obtain more business opportunities by mastering ship dynamics at ports and contacting shipowners in advance.

type

From a technical point of view, there are three main monitoring methods:

1. Coastal CDMA network monitoring

Namely through China Telecom (formerly China Unicom) CDMA network to achieve the dynamic monitoring of coastal ships.
This monitoring method requires the ship to install transmitter, the shore-based installation of receiving equipment, through CDMA network to achieve ship dynamic data transmission.
The obvious disadvantage of this monitoring method is that it can only be used in coastal areas with CDMA signals, so it is suitable for coastal transport ships.

2. Satellite monitoring

The transmission of ship position data to the company through shipborne satellite transmitters and receivers.
This method is not restricted by the sea area where the ship is located, so it can better realize all-weather monitoring.
However, the significant disadvantage is that satellite communication is expensive and not suitable for continuous monitoring.

3. Coastal AIS system monitoring

It means to grasp the ship dynamic data in real time through the signals sent by the shipborne AIS system.
AIS, which stands for Ship Identification System, is mandatory for any ship in the world over 500 gross tons, so it covers a very wide range of ships.

Since the signal transmitted by the AIS system can only cover the surrounding distance of 30 nautical miles, the dynamic monitoring of ships in the port area can only be realized through the AIS system.
