Different methods of data processing are used in Wialon. Some of them are as follows:
Real-time data processing allows for quick acquisition of data on trips, sensors, ignition, fuel, counters, speeding, and is used:
The data obtained as a result of such processing is bound to time and constitutes time intervals.
When data is processed in real time, mileage is calculated only by GPS, regardless of the mileage counter selected in the unit properties.
All the data sent by trackers go to the database that stores it in the form of messages. Every time the user wants to obtain summary data (for example, when executing reports or viewing tracks), a request is directed to the database and the system processes all the messages for the indicated time interval.
In most cases, both mechanisms of data processing give the same results. The discrepancies might arise for the following reasons:
If you change the unit properties, the recalculation of the data processed in real time is carried out automatically in 15 minutes. In the case of processing messages from the database upon request, the changes are reflected immediately.
The data processed in real time is not recalculated in case of deleting or importing messages.
