Vision and Challenges for Realising the Internet of Things

eader was tested to survive the outdoor temperatures and to operate under vibrations and
shocks at the levels specified in ISO 15003 (2 G vibration at 10–2000 Hz, 50 G shocks), which
specifies the environmental resistance testing for electronic devices for agricultural machines.
The reader is enclosed into a robust IP67 casing. The reader prototype is shown in Figure
4.9-3 together with a reader set-up at a saw mill.
The RFID reader is controlled over a CAN-bus in the harvester using EPCglobal’s Reader Protocol.
For implementing the Reader Protocol over the CAN-bus a new Messaging/Transport
Binding (MTB) was developed.
Figure 4.9-3: Developed RFID reader for the harvester and a test reader set-up at a saw mill.
At the saw mill, commercial RFID readers (Sirit IN510) were used with specially developed
software for log identification and singulation. The readers were placed into robust aluminium
casings to protect them from possible impacts, dirt and dust. Robust metal antennas (Intermec
IA33D Antenna Cell) were integrated to the reader casings. The integrated reader set-ups
were positioned over the conveyor at the log sorting, where the logs are received at the saw
mill, and at the saw intake, before the logs are sawn into boards, at two saw mills; one in Sweden
and another one in Finland. The reader position over the conveyor allows the reader installation
at the saw mills with minimal changes to the existing conveyors. A read rate of approximately
100 % was achieved for operating transponders inside the log ends in the tests at
saw mills. The read rate is affected by the survival of the transponders in the logs, which depends
on the success of the application into the log end. Transponders that are not fully inserted
are vulnerable to damage during the handling of the logs.
2.2 Traceability services
Indisputable Key project’s view of traceability is more than just knowing the location of an
object. In addition to location information, the information related to the production/processing
throughout the supply chain is gathered, e.g. processing conditions and wood
quality parameters.
Traceability Services (TS) enables traceability and visibility of products in the distributed supply
chain. By rolling out Traceability Services the organisation can monitor and analyse the
efficiency of its processes and value chain in real time.
Traceability Services
Connects the steps of the supply chain together
Provides a common data model for the whole supply chain
Enables statistical and logical analysis of large sets of transaction data which can be used in
Enterprise Resource Planning
Provides the metrics to monitor and analyse the performance of a company.
By combining the process information of the supply chain and the traceability data about
products travelling through the supply chain Traceability Services enables new methods for
analyzing the performance of the organisation. The modules of Traceability Services have the
capability for receiving and processing environmental product and process properties.
The performance of products can be compared and analyzed between different steps; e.g. how
the environmental performance of products is affected by the use of different transport processes
having varying environmental properties (diesel vs. biodiesel as the energy source). Another
possibility is to analyze how a certain product property affects another product property.
For example, how the area of origin of the log affects the board quality.
