Basics
EnOcean is a battery free radio system that has been developed by the
company EnOcean in 2001. Due to the short signal length of 0.5ms and
10mW transmitting power the radio system technique has an energy
requirement of 50µWs. For this the system uses the energy of smallest
changes of pressure and temperature as power supply for the sensors.
The reach of the sensors is up to 300m out of doors. Additionally, every
transmitter gets an unique 32Bit address as ID during manufacturing. The
modules are using the internationally accredited SRD frequency band an
869 MHz.
Main points of usage of EnOcean are building automation, industrial
production and automotive.
•
Minimal energy requirements
•
Support of several transmitters in the immediate environs
•
Telegram length 0.5ms
•
Transfer reach up to 300m
•
Mono- and bi-directional communication
•
Easy extensibility
As modulation procedure EnOcean uses the incoherent amplitude -
modulation (ASK). The error likeliness is nearly the same compared with
the frequency modulation at identical interference signal level. The digital
amplitude modulation allows the realization of energy saving transmitters
because here only the "1"-Bits are transferred.
The transfer of a data telegram takes about 0.5ms. To enhance data
security every telegram is repeated two times within 40ms, whereat the
time lag between every repetition is perchancely.
This fast multiple sending allows that many neighborhood transmitters may
be working parallel together on one radio frequency with a low error ratio.
EnOcean uses IDs for the addressing. An ID is an compound of
ID base
and a freely configurable
bit area
. Since the EnOcean modules are
delivered by VIPA with a different
ID base
with extensive projects it is
recommended to note all
ID base
of the modules. So on error an module
can be replaced and the appropriate
ID base
can be taken.
For this details can be found at "Exchange module and set ID base".
