General information on telemetry

a means of acquiring, formating, transmitting and publishing technical data

a means of automating the water installations operation

The W@de range

RTUs vs Gateways

Benefits of the W@de solution


Acquiring, formating, transmitting and publishing technical dataTelemetry is a means which makes it possible...

to acquire technical data on installations distributed on a great geographical area (status, measurements, counters) ;

to formate them (alarms, logbooks, samplings) ;

to transmit them automaticaly and in a sure way to a SCADA, and/or to operators of maintenance by using different media and communications protocols ;

mediaprotocols

to publish them in the form of logbooks, curves, synoptics, reports ;

to control the operation of the installations remotely.


Automating installations and water networks

Telemetry is a means which makes it possible...

to automate the local operation of the installations (PLC function)

To automate the distant remote control of the installations*

* only if the media makes it possible

Technical data

DIG (Digital) : 1 / 0 ; True / False ; Yes / No

Example : contactor On/Off

MEASURE : analogic or numeric value ranging between two limitsExample : level, flow, presure, temperature, pH...

COUNTER : numeric valueExample : operating time of a pump, distributed volume...

DATE : Day / Month / Year Hour : Minute : SecondeExemple : 04/22/23 00:24:22

TEXT : alphanumeric character stringExample : THERMICS FAULT ON PUMP 3 DRILLING N° 2

The combination of theses informations makes it possible to manage technical dated data

Transmitting technical data

the informations are transmitted... from a RTU to another RTU from a RTU to the SCADA from the SCADA to the RTU from the RTU to the maintenance

operators from the SCADA to the maintenance

operators from the maintenance operators to the

RTU and to the SCADA

… by using different media... permanent : LL, Ethernet, GPRS periodical : radio occasional : PSTN, GSM

… and communication protocols adapted to the transmission of time stamped informations and to the media.

mediaprotocols


Publishing technical dataThe publication of information consists in making them easily exploitable by the operators which are in charge of the exploitation and the maintenance of the installations.

Displaying, printing and transmission of alarms for

the maintenance operators

Displaying of status and values for the

maintenance operators

Displaying and printing of reports for the

exploitation operators

Displaying and printing of curves for exploitation
