The entry process of the ships to ports, the course to be followed in the navigation inside the port, the reference points,... all these processes are indicated and carried out with a special maritime signaling. The light signals must be synchronized with each other to avoid sending wrong information to the users.
It was needed a system that could be integrated and embedded with the different types of maritime signals. A system that could guarantee such synchronization and that could allow a remote control of each one.
We have designed, developed and manufactured an electronic system that can be embedded and integrated into each one of those light signals (buoys, flashlights, beacons,...) and that allows a precise satellite-controlled synchronization.
Besides, we have included a great value-added service to this system by providing digital outputs and a GSM module that allows you to manage the different signals and to configure the device remotely.
The river and sea buoys are essential equipment for navigation and they are anchored to the seabed through different systems to retain their position. If that anchor gets broken, they will go adrif. That means a huge security risk for the navigation and a great cost in their search and recovery.
It was needed to keep all buoys localized at any time and know for sure if they lost their position, as this would greatly reduce the costs of their recovery and the navigation risks.
We designed a completely watertight device with GPS and GSM systems that can withstand the inclement weather that a buoy is exposed to. Such device is easily installed and integrated into the buoy itself allowing their location with less than 2m accuracy. This device sends SMS alerts if it leaves its radius of displacement previously set, notifying its position at a configurable time interval.
With this system the recovery costs are minimized because the ship will be sent only in case of real alarms, saving fuel and time. The exact position of the buoy will be known and the risk for the rest of seafarers will be reduced. The devices are fully configurable by SMS and have an easy maintenance.
We were part of a team whose goal was to develop a mobile vehicle armed with all the technology necessary to perform actions in situ, like comprehensive maintenance, optimization and control of a photovoltaic facility.
It must be a system that could access to narrow terrain of hard access, energy self-sufficient and able to maintain the right working temperature of the instrumentation.
Our participation consisted in develop, on the one hand, an embedded hardware system that was installed in a vehicle to identify the most relevant elements of the photovoltaic plant, to locate the mobile laboratory at any time and to issue alarms in case of theft.
And, on the other hand, implement a user interface which displayed in real time the acquired data, the exact position of the vehicle over a CAD map and the robbery alarms issued.
In this way it is generated a data base for each installation with the GPS coordinates of inverters, production meters, series of panels, anti-theft devices, and the data acquired in each supervision.
