The DataStation E3 is a data concentrator (Data Logger).

It collects the information from various measuring equipment:
Sensors, electric meter or fluid counter, pulse concentrators, PLC's, etc ..

With an ARM core Linux OS, it has a powerful processing intelligence that allows it to filter, calculate and store information before sending the software E³Manager.
 

E³ Link : the protocol of communication resulting from the experience of exhibition centres (processing capacity of 3000 terminals in real time).

E-cube Link transmits safely and in real time the data collected to e-cube Manager, thanks to wireless or landline communication networks.

 

The software is a multi DataStation E³ administration console.
It also allows to view data in different forms with a simple and efficient access.

E³Manager stores data in a SQL or PostgreSQL open source database in SAS mode or on a local server
It has multiple interfaces to make data available to external software processing and analysis.

 

The DataStation E³ manages three types of data:

Primary data (D_cpt):

These are the data collected from the meters or connected to the DataStation E³.
The recovery of the primary data is made at a speed depending on the number and performance counters.
Speed recovery and data integration in the DataStation E³ is 500ms maximum for 100ms maximum frames at a transmission speed of 38,400 bits / s.

In addition to the index, DataStation E³ can integrate up to 8 electrical quantities for each phase, 24 sizes in total.
 

Continuously transmitted data (D_t) :

The data continuously transmitted are calculated from primary data from the meters over a period of time.

The user has the choice between two frequency calculation every 10 minutes (FMax) or every 60 minutes (FMin).

The DataStation E³ calculates on the period chosen the Max, Min and Average of each size.

Dt data are transmitted to the software E³Manager at the frequency chosen by the user (Fmax or Fmin).
In addition to the calculated data, the DataStation E³ sends the index counters at the same frequency as that chosen by the user.

Data transmitted on Events (D_event) :

Each DataStation E³ has an automatic frequency variation mechanism based on exceeded preset thresholds.

The frequency of calculating D_event data is faster than the data D_t.
The wind shadow data is calculated every minute to Fmax and every 10 minutes at LRL and stored in flash memory of the DataStation E³ in FIFO (First In First Out).

The data is transmitted to D_event E³Manager software only if they exceed a threshold set by the user:
The E³Manager software allows to set two thresholds for each value.Threshold max and min threshold which are constantly compared with the values retrieved counters:

• Threshold max (S max): An event is triggered if the counter value exceeds the maximum threshold,
• Threshold min (S min): an event is triggered if the counter value falls below the minimum threshold.

By setting both a value for Smax and Smin, the user has the possibility of setting a tolerance level to avoid repetitive alerts and without major object.

   Interest: Visualization of event data helps identify a potential problem, with a set of precise values around the event (6 to 10x more data).

E3 DataStation data concentrator has a "memory" feature that allows it to transmit data prior to the event!

Once a threshold of event is exceeded, the DataStation E³ transmits data prior to the event  (10 'data Fmax or 60 data LRL), to the software E³Manager, in addition to the data collected during the time of the event.

 The past data recovery software allows the user E³Manager to know precisely the status of actions before the occurrence of the event and thus to have a valuable diagnostic aid.

The DataStation E³ is able to generate two types of events:

Events due to malfunction of systems:

The DataStation E³ is capable of generating an event in case of breakdown in communication with an element of the system (meter, power measurement, input / output module, etc.).
The event is triggered if the DataStation E³ is not able, for a given time, to recover the data from the malfunction element.

• When connected continuously, the event is transmitted to E³Manager software.

• When not connected continously, the event is stored in the memory of the DataStation E³ and automatically referred to E³Manager software as soon as the communication is established through an automatic synchronization mechanism.

 

Event due to threshold crossing

The DataStation E³ is capable of generating events if thresholds is exceeded over a specific value.
The time between the threshold is exceeded and the event generation can be set from the software E3Manager with an adjustment range from 0 to 60 seconds.

 This variable is useful to eliminate false threshold overruns generated by interferences or transients, as the engines start.
