Remote Monitoring & Control System for the Mobile Telephony Base Stations

Evaluation of Energy Consumptionat the Base Station Installation

Tas

k 1


Measures the total energy consumedand its distribution to the Devicesinstalled at the Base Station.

It is necessary for making the best decisionto reduce the energy and fuel demand.

It is highly recommended before every attempt for energy

optimization of the Mobile Telecom Base Station.

For existing old-fashioned Base Station Devices,

not supporting serial communication

the monitoring is performed by external hardware

measurement of the currents and the voltagesat the input and output connections and by

sensing any special signaling outputs (dry contacts etc).

the control is performed through relay contactsto the appropriateinput, output and control connections.

The system consists of an integral

set of hardware and software:


The hardware part of the systemis Modularand consists of various typesof interconnected units,depending onthe installation structureand the desired operation. D

The interconnection of the various units

is simple and reliable,by a single cable in a daisy chain (or even star) layout, implementing the ‘Z-Bus’,(consisting of a

special RS-485 optically isolated bus

and a galvanically isolated power bus).

Due to the simplicity of the interconnection and the galvanic isolation

the units of the systemcan be ‘physically decentralized’and be mounted to proper rooms and positionsof the installation,near-bythe monitored Base Station devices and

sensors,in order to minimize local wiring.

Linking to the Base Station Installed Devices*

is through serial ports implementing bothRS-232 and RS-485 communication

protocols.

* For devices not supporting serial communication, there is provision for:

measurement of AC-current at four supply lines

(by means of, external current sensors) the detection of two signal dry contacts the stimulation of two control inputs by the two

relay output contacts of the unit.

Energy Measuring Unit(p/n 840303)


It is a totally insulated, small sized deviceattached directly to the ac supply conductors,thus minimizing installation labor.

It measures on a 3-phase system,true-rms ac voltage and current,active, apparent and reactive power per

phaseand accumulates energy (KWh),in two independent counters (optionally

resettable).

Alarms


The on-site units may be programmedto generate alarm conditions,according to measured values

in order to: apply on site controls handle undesired conditions.

These alarm conditionsare reported to the serverand they are available as reported

alarms.

Additionally, the server side softwaremay detect alarm condition,while processing reported data.

All the alarms are handled by a versatilealarm ticketing and processing

system.

It creates ‘Tickets’which are presented in the form ofhandy, user filterable lists.
