AMI radio network

AMI (Anvanced Metering Infrastructure) networks are solutions with the highest functionality, but require some experience and diligence during implementation, especially in the wireless version. The fashionable concept of "smart metering" is very often associated with these assumptions. It should be noted that this concept does not necessarily relate only to electricity meters, but more broadly, to utility meters, and that the implementation of AMI networks alone does not mean that we are dealing with smart metering. Below you will find a description of a radio solution dedicated for multi-family housing for water and heat meters. It can also be successfully used in commercial construction and in industry, including gas and electricity meters. A broader description of the wireless industrial solution for monitoring production media can be found here.

Fixed radio network

System infrastructure

To build a fixed network, in addition to radio meters, you need devices that will provide automatic meter reading and then send data to the server to which we have access. The key issue in building the system is to ensure that all meters are read, regardless of changes in radio wave propagation. This propagation depends on the environmental conditions, the level of radio interference (background) and the temporary obstacles between the meters and the radio receiver. Therefore, building such a system in an optimal way, requires measurements of radio wave propagation and determining the correct location of the reading infrastructure devices. This reading infrastructure is at least a radio receiver and a communication gateway. GPRS gateway The radio receiver reads the meter index states, which are then read by the communication gateway and stored in its internal memory. The entire radio system uses the OMS compliant wireless M-Bus communication protocol, thanks to which meters from different manufacturers can be used, and the read infrastructure once built is independent of the legalization of meter replacement. The data collected in the communication gateway is then sent to the selected server: FTP, HTTP or SMTP. Depending on the type of gate selected, this transmission takes place using a cellular network (GPRS or LTE) or with the possibility of connecting to a computer network, using the Internet / Ethernet (LAN, wLAN).

The benefits of using a fixed network

The implementation of a fixed radio network has a number of benefits resulting in a quick return on investment.

  • Fully automatic meter reading without human intervention
  • Daily balancing of the facility - immediate detection of irregularities
  • Daily hourly data transmission - immediate information about irregularities from the last 24 hours
  • Quick liquidation of leaks, manipulation attempts (inverted meters, dismaunting of the radio module, etc.), thanks to current information
  • Accounting for recipients at any time (e.g. when changing recipients)
  • immediate detection of damaged water meters
