Introduction► Maven systems is a product engineering company with an

expertise in providing end to end solutions for automatic meter reading.

► AMR solutions are based on LPRF, PLC and GPRS technologies► Hands on expertise on ZigBee, proprietary mesh, 6LoWPAN,

DLMS, Modbus, KNX, M-Bus protocols to name a few.► Multiple pilots based on LPRF based technologies are in place

based on Sub 1 GHz (865- 867 MHz) and 2.4 GHz technologies.

► Both technologies have their set of advantages / disadvantages and in the course we have benefited with substantial learning and observations about implementations of AMR.

Deployment scenario

AMR Frame work

Pre requisites of a successful AMR implementation► Robust and appropriate technology for last milestone connectivity

► Ease of data collection with user friendly customer touch points

► Ease of implementation and deployment

► Reliable system with low maintenance

► Lower implementation and operational costs

► Stable and self healing networks

Important

► Capability to capture accurate base line data which could be closely linked with generation capacity and distribution management

► The implementation should be scalable to a AMI, smart grid implementation with minimal changes and efforts.

Maven’s mesh network protocol

Topics

► Adhoc on-demand routing

► Mesh advantages

► Data concentrator

Adhoc on-demand routing► Network is silent until a connection/ data is needed

► Eliminates the efforts of identifying the locations for the coordinator, routers for data fetching. o In case of ZigBee if the coordinator fails then data cannot be

fetched till the time coordinator is restored and the network is created again.

► Installation process is simpler and connection setup delay is lower

► Data can be fetched on demand and / or at regular interval

Mesh advantages► Cost effective and dynamic high bandwidth networks over a

specific coverage area

► Self healing in case of failures of one of the meters in the path

► Auto discovery helps identify the newly introduced meters

► Reduces the efforts of meter commissioning

► PAN ID is used to create the specified coverage area

Data concentrator► Data concentrator can cache the history data up to 1000 meters

along with time stamp as it has larger memory available.

► DC has a list of meters to be polled and the polling duration at which the data can be cached from meters.

► DC uploads the cached data when GPRS connection is available else would store the data and upload it offline when GPRS connectivity is available.

► Cached data on server can be used for billing, plotting the usage patterns and / or energy profiling.

► Hand held unit can also collect the cached data from the DC
