The mar.vijalight.com software remotely monitors VIJALight® lanterns with built-in monitoring (VIJA-370COM, VIJA-412COM, VIJA-540, VIJA-540AIS). Each lantern finds its position by GPS and sends reports to the server over the 4G mobile network.
- Shows every aid to navigation on a Google digital map.
- Lists aids to navigation with their position, operating status and alert status.
- Produces reports on the lanterns along a route and exports them to Excel.
Map
The Map view shows the whole aids-to-navigation system at a glance.
Click an aid's icon to see its details: code, type, set position, last position, distance from the last position to the set position, status, current, voltage, year of manufacture and managing organisation.
Lantern details
Click Chi tiết thông số (details) to see the movement route, voltage chart and data history: every report sent to the server, with its date, time, status and coordinates.
Movement route
Click Lộ trình di chuyển (movement route) to see the coordinates the lantern reported at each point in time.
For example, lantern QG182P2CP was installed on the Tien River in 2019. When it was stolen and put on a boat, the software showed its route as below.
This lets managers see where a lantern is now and where it has been, and plan how to find and recover it. In practice, many buoys that broke their chains in storms and floods or were hit by vessels, and drifted out to sea with their lanterns, have been found and quickly recovered this way.
Once the lantern is back at its original position, it stops sending off-position alerts automatically.
Voltage chart
Click Đồ thị điện áp (voltage chart) to see the lantern's voltage over time, so managers can judge the current condition of its battery.
Aids-to-navigation list
The list shows full information on every aid and can be filtered and sorted by installing organisation, management station, status, year of manufacture, code, type, managing organisation, river route, phone number, distance, voltage, current, clearance, flash character and last update.
It also shows the total number of aids and how many are in each state: normal, off position, battery alert, lantern alert, signal lost and under repair. Click any aid to open its details, movement route, voltage chart and update history.
Reports
The software produces statistics by type of aid, installing organisation and managing organisation, plus a report of lanterns off position, and exports them to Excel.
