DATABASE SOFTWARE REQUIREMENTS - definition
DATABASE SOFTWARE REQUIREMENTS -. AirLink is an "open" system. All data is fed to a flat-file database that is accessible to other system software (such as billing systems) in use by the utility. No special software interfaces are required to access the AirLink database. Alternative systems generally require a custom-designed database structure. NETWORK MANAGEMENT SOFTWARE REQUIREMENTS - AirLink provides, as part of its overall system, software to enable system management in conjunction with the database. This software is primarily used to create and transmit commands (read, status, etc.) to each data point (meter) in the system. It will also manage the protocol that polls meters and reports anomalies in meter status (power interruption, etc.) The basis of this protocol is that there are 10,000 data "slots" per second. Slots are available for status changes, etc. DISTRIBUTION AUTOMATION (SCADA) - The AirLink system enables utilities to use its components for distribution automation (SCADA) applications, including monitoring switching stations, load management, etc. Each AirLink module that is deployed for this purpose becomes an individual data point in the system and is managed by the network with a specific protocol and command structure. OTHER FEATURES - AirLink provides a number of other features and functions; some of which are unique and others which are competitive. These include remote connect/disconnect of meters, remote configuration of data points, demand metering, tamper and outage detection and advanced metering features for large-scale industrial users.
