Generally, the definition of 'remote monitoring' is getting to know the status or conditions of operation, without having to be physically present on site.
WM-RMS2000 remote monitoring system consists of a master terminal unit connected to the workstation (installed with window-based software), communicating with a route terminal unit being installed inside the AtoN itself. (Refer to Figure 1.)
This communication link can be accomplished using an appropriate transmission network (VHF, GSM-GPRS, Satellite, AIS AtoN, etc.), depending on site situation and end-user's requirements.
Basically, Wealth Marine's Remote Monitoring System consists of 3 main components, namely the Master Terminal Unit (WM-MTU2000), Route Terminal Unit (WM-RTU2000) and a computer hardware/ workstation (PC with window-based Operating System).
WM-RTU2000 Route Terminal Unit
Wealth Marine's WM-RTU2000 is being installed inside WM-CL150A LED Marine Lantern. It is capable of changing the flash character of a marine lantern, has an automatic alarm system, and can be readily connected via transmission system to transmit data to the control centre (Master Terminal Unit WM-MTU2000) directly.
This intelligent Route Terminal can also execute instructions preset by the control centre for remote monitoring and control purposes.
Output Data Transmitted from the lantern (WM-RTU2000):
Automatic Alarm Reporting of WM-RMS2000:
WM-MTU2000 Master Terminal Unit:
The Master Terminal Unit (WM-MTU2000) only consists of the MTU2000 communication PCB and a power supply PCB for various distributions (indicators). The size of the housing can be customized to integrate into existing systems with space limitation or as per end-user's preference.
The Master Terminal Unit is located at the control centre and is able to:
Basic features and standard indications on the housing panel includes:
The MTU2000 communication PCB simply manages the data transmission via the GSM module mounted on the same board. A socket for a local SIM card to be inserted (like mobile phones) is also situated within the same PCB.
The MTU2000 communication PCB provides a display access via RS232 or RS485 serial interface and therefore, connection to a desktop PC or laptop computer would be readily available. The MTU2000 communication PCB and a power supply PCB could be housed inside a compact box (handheld unit) or inside a desktop module.
