1) Store data offline on site

For mobile applications, it is important to store data on site with the application. For this purpose, the Avisaro data loggers use USB memory sticks or SD card memory cards - which are very large at several GBytes. As long as your vehicle, forklift, watercraft, ... is on the move, the data is stored securely on site - regardless of whether there is an online data connection.

2) Upload with a time delay

If a data connection can be established later, the saved data will be uploaded to a server. As a rule, a new file is loaded onto the server every hour.
Depending on the Avisaro product, WLAN, LAN and mobile communications (LTE) are available as data connections. This makes this application equally suitable for company premises and worldwide use.
The simplest server is still an FTP server. The data is stored there in the form of individual files. Amazon and Google Cloud services will be available soon, as will MQTT data upload. A suitable FTP server can be rented from Avisaro, typically this can be provided by your company IT or Internet provider.

3) Download data and evaluate as needed

The data servers are now ready for further processing. The data is downloaded automatically or manually from a desktop PC. This depends on the details of the application. In most cases, applications adapted to the respective application are used - it is quite easy to automate this evaluation.
The free “FileZilla” FTP program can be used for easy downloading by hand. Many users use ordinary office tools such as "EXCEL" for the evaluation - or MathLAB or simple Phython scripts. Avisaro is available to you to create customized evaluation tools.

4) FAQ

What if the data connection is lost during transfer?

The data transmission is then repeated. This can be clearly seen on the FTP server because all data is initially written to a temporary file.

Will the data in the data logger be deleted?

Typically, the “ring memory” storage mode is set. All data remains stored locally until the storage medium is full. From then on, the oldest files are deleted to make room for the new data. With storage sizes of several GBytes, this means that the last few months, if not years, remain stored on site for security reasons.

What happens when local storage is full?

The Avisaro data loggers can be configured as a “ring memory”. The local memory is first written until it is full. The oldest files are then deleted to make room for new data. With memory sizes of several GBytes, you can achieve a history (“memory depth”) of several months or even years. With this setting, the data logger never stops recording.

Alternatively, the logger can be configured to stop recording when the local storage is full.
