Radiocrafts (Oslo, Norway) is seeking to patent several of the unique features and methods used in the implementation of its Wireless M-Bus modules which are used for automatic meter reading (AMR) and smart metering.
“As a leading technology and solution provider it is very important to protect our IP, and using patents is one of the means we have to do this,” said Peder Martin Evjen, Managing Director of Radiocrafts.
The main features covered by the patent are innovations to handle a multitude of slaves (meters) by one master (concentrator or MUC), while meeting stringent timing requirements and using a minimum of memory resources.
In particular the patent covers the methods used to meet the timing requirements for a master, using an address register, a flag register, an encryption key register combined with an auto-message generator for standard messages and its combination with a mailbox with pre-generated messages or templates, and a given message priority, depending on incoming messages.
The company's modules include solutions compliant with the Dutch Smart Metering Requirements (DSMR / NTA 8130), and the Open Metering System specification (OMS) initiated in Germany. Radiocrafts is actively participating in the standardisation work of OMS, and in the CEN Technical Committee 294 reworking the EN 13757 (M-Bus).
Radiocrafts also offer its Wireless M-Bus IP for licensing to customers implementing and deploying large scale AMR systems.
