METER READING and M-BUS AUTOMATION

The M-bus is an inexpensive solution for widespread networking and remote meter
reading for large numbers of heat meters, gas meters, water meters and energy meters from
various manufacturers. The task of reading outsmall amounts of data per energy consumption
meter at fairly large time intervals places only minimal demands on transmission speed, and
allows for very long transmission distances using simple, standard cables. The M-Bus
(meter bus) is based upon the European standard for heat meters, namely EN 1434-3,
with regard to data exchange and interfaces.
1.1 System Overview
Consumption meters distributed throughout homes and industrial operations are connected
via the M-Bus to a central master, which supplies all of the interconnected meters with
electrical power, gathers data, generates consumption profiles and forwards them to the
master consumption logging and billing point. Data is transmitted to the meter reader.s
pocket PC either directly via serial interface,indirectly by means of modems via public
telephone lines, or via an optical interface (IrDA).Incoming data are collected at a server and
are saved to a database. Various users are then able to visualize and analyze the data
using clients and appropriate software products, or export them to EXCEL
for processing. A web server application can be used to process the data, thus allowing for worldwide available on the Internet.
Where large complexes are involved, M-Bus consumption-billing data are often transmitted
to parallel installed building service control systems, where they are processed as part of
the facility management concept. Corresponding links between the two systems
are implemented either at the lower level by means of protocol converters, or at the upper
level using databases. When consumption logging devices are retrofitted at locations where no M-Bus had previously been available, data can also be transmitted by radio and then incorporated into existing M-Bus installations. This method is being used to an ever greater extent for retrofitting billing systems in real estate holdings.
1.2 User Benefits
Use of the M-Bus for remote reading of consumption meters offers various advantages to utility companies, billing service providers and end users:
! Fast, error-free reading
! Simple processing of electronic data
! Accelerated receipt of payments thanks to immediate billing as soon as consumption data is gathered
! Minimal remote meter reading personnel, even for difficult to access meters
! Preservation of the customer.s private sphere
! Meter reading on short notice reduces costs associated with meter replacement and tariff changes
! Acquirement of statistical consumption data allows for system and tariff optimization
Broad acceptance of the M-Bus amongst meter manufacturers, planners, installation technicians and end users is achieved by means of:
! Minimal additional costs for connecting the consumption meters to the bus
! Use of a commercially available, easy to use technology
! Good interference immunity and secure data transmission
! Open system with international standardization
M-Bus is based on the "meter bus" standard. This uniformity of the interface is a great advantage of the wired meter reading system: devices of different manufacturers can be operated without problems at the bus. The M-Bus can also be used for all types of consumption meters as well as a variety of sensors and actuators.
The M-Bus system is used for recording consumption data, mainly for heat and water meters. Compared to radio systems, wired systems make sense wherever meters have to transmit instantaneous values or where a few meters for central recording are spread over a large area.
