Datalogger

Datalogger for windpower business

In collaboration with Euroservice Group, a leader company of meteorological towers installation in Italy and around the world, and Q-Life Group, leader company in projects design and development of green power plants, FST is developing a new datalogger for windpower business.
The datalogger has been design to automatically acquire and store data in long period. The first application is in windpower business, but thanks to the flexibility of the software and to the wide range of input types in the hardware it is possible to use it in various applications. The main parts of the datalogger are:

  • The data acquisition module, the main part of the system;
  • The energy supply module, with a 12V battery, a spair 9V battery and a 3V battery used for the system clock;
  • The recharge battery module, with a solar panel and a batteries charger;
  • A GPRS/EDGE module for data transmition (replaceable with a sat modem);
  • A LCD display used for debugging and data visualization in loco;
  • A watertight box IP65.

Main Features
The system has:

  • Up to 41 input channels divided between digital, analogical, in current and gray code;
  • The possibility to read from each input channels every second and the elaboration can be done with frequency of 1 minute, 10 minutes, 1 hour or 1 day.
  • It is possible to acquire: average, standard deviation, maximum value, minimum value, time of maximum, time of minimum, sample, cycles or 3-second gust.
  • The system guarantees functionality in range -40 °C < Ta < 85 °C
  • The system has a relè to activate the sensors warm up;
  • The system store data into an SD memory ables to store for years all the values acquired from the sensors and the elaborations, plus it has a flash memory to preserve the functionality of the system from errors and SD corruption. The flash memory has also the capability of up to 60-90 days of data;
  • All data acquired can be sended via modem periodically;
  • The system is configurable, using a direct connection via USB to the computer, using a USB storage device or using a internet connection;

State of the art
A long period test is in progress, which means that dataloggers are installed and are working to verify the funcionalities and to validate the system. This important step will come out with a safe, reliable and efficient product.
The distribution of the product is expected to be on the second quarter-year of 2012.
