Key roles - conditional reconnection. Change of integration period in case of 15-minute power. Voltage threshold for phase presence decision. Change of maximum power limit. Change of registers within profile framework. Change of profile periods. Voltage thresholds related to electricity quality. Meter software change. Credit change for Pre-Paid meters. Message sending to the customer Communication functions Concentrator is in communication terms realized as the device communicating with two sides: on one side there are electricity meters located in the substation region where the concentrator is also installed, while on the other side it communicates with AMR Centre. The connection via both communication paths is bidirectional. Communication with meters goes on via RS485 or PLC (Power Line Carrier) communication. Communication with AMR Centre goes on via RS232, MODEM, Ethernet or GRPS communication. Communication with AMR Centre is initiated in several ways: According to automatic concentrator response sequence. According to emergency request of the concentrator. Upon the request from AMR Centre. Data processing functions Concentrator software performs partial processing of collected data. Concentrator executes initial data processing collected up to that moment, in the manner not affecting data reading, parameterisation and delivery. Data processing function processes alarms and statuses of meters, electricity supply quality logs, event logs, with the making of corresponding reports after finding corresponding alarms, statuses and events to be sent to AMR Centre upon emergency request of the concentrator. This function processes events and alarms related to the disruption of meter integrity (e.g. opening of termination cover), as well as attempt or disruption of data integrity in the meters themselves (e.g. meter reprogramming attempt, etc). This function performs analysis of voltage circumstances on meters themselves, since there are corresponding records in electricity delivery quality register recording voltage drops below agreed voltage thresholds and supply interruptions. In this manner, this function would indicate poor voltage circumstances of one or a group of customers and it would serve as the reason to send crews into the field. The concentrator also automatically informs AMR Centre on the detection of new meters in the subordinate substation region. Data and access protection functions Access to data and functions of the concentrator is protected by authentication and authorisation procedure. Concentrator creates access logs both for local and remote access through communication channels. Concentrator supports communication encryption with meters and with AMR Centre. Administration functions Administration function can be done locally or remotely. It provides: Review and synchronisation of reading programmes/sequences with AMR Centre or a laptop. Review and synchronisation of management/parameterisation programmes/sequences with AMR Centre or local laptop. Review and change of programmes/sequences execution priorities. Real time clock synchronisation. Review of communication routes. Review and change of concentrator reporting time and frequency parameters. Review and change of communication parameters of concentrator. Review and change of all other concentrator parameters. Change of concentrator management software.
