Technology for a new Meteorological Monitoring Strategy

By: David FARHI – Envitech Ltd.

Typical Automatic Monitoring System

Meteorological data is measured at many locations using a variety of data collection devices.

The Typical AMS data collection process involves initiating a communication link with a field device using telephone lines.

The Central data collection site detects that it is time to get data, initiates a call, waits for a connection and issues a data request for the field device.

At the remote site the request is decoded and the device packages up a response.

Enhanced Real Time delivery of data

Significant benefits accrue in the Envitech TCP/IP data collection network design:

High Speed, simultaneous data collection from all nodes. Event based (Alert) messages, Continues reporting during

episodes and other events. Long distance charge eliminated, a connection to local Internet

Service Provider is used . Rich data sets, PC Based data acquisition can support cameras

and other visibility devices. Real Time Information, PC based DAS’s host their on web sites for

data presentation, diagnostic and reporting. Universal Inter-Network data exchange, any organization’s could

subscribe to receive data from any site.
