The small size of its units, components reliability, installation simplicity
and flexibility, as well as data transmission security, all within a reasonable
price, make the SARP a highly rentable product for any company users.
SARP is the only system that simultaneously manages consumptions of
electricity, water and gas counters provided with open/closed contact pulse
output type.
Pulse Memorizing Unit - UMP
The UMP is the "heart" of the SARP. Manufactured with modern
technology, SMT, ASIC, CMOS, etc., the UMP is the system element
that identifies, counts, and stores pulses sent by the counter.
Each counter needs one UMP.
It has a capacity of up to 4.294 million pulses.
The undeletable serial number (arranged as a drill code into the same
printed circuit), identifies each UMP among others within a total
number of up to 16,7 million units.
Up to 512 UMPs can be connected into the same bus. Their positions
in the bus are coded with "jumpers".
No connection to the main power is necessary, since its very low current
drain, under 6 microamperes, will guarantee data retention for a minimum
of ten years from a Li/Mn built-in battery.
All UMPs in the same bus are read from a single connection point.
A couple of wires connect the counter pulse outputs to their respective
UMPs.
All UMPs, whatever the nature of counter pulses received, electric
energy, water or gas, can be connected to the same bus.
Each UMP and its connector are housed in a fire resistant Celanex
box, hermetically closed.
Under demand, the box can be manufactured with different materials or
shapes, even containing more than one UMP.
The physical support of the UMPs connection bus can also be manufactured,
under demand, with different configurations or protection levels depending
on the application (electric energy alone, water or gas, or some of them
together).
Data Transceiver Processor - PTD
The PTD is the equipment that provides "intelligence" to the
SARP, besides being the system that links, via a bidirectional radio, the
UMPs and the user company.
Every PTD will accept between 1 and 4 buses with UMPs. This means
that up to 2048 Electricity, Water or Gas counters can be connected to
the same PTD simultaneously.
Each PTD carries a different number of particular calling codes,
between 1 and 4, that identifies it within a million possible installations.
The modular design of the PTD makes easy its installation as
well as any modification, thereby adapting to specifical requirements of
user companies.
According to the communication method, there are several PTD
equipments,
-
PTD Radio UHF (at 411,375 MHz and 411,425 MHz)
-
PTD Radio VHF (at 71,375 MHz)
-
PTD Modem STN (2,400 bauds through Switching Telephony Network)
-
PTD Radio Coaxial (coax cables transceptor)
Mobile Unit Processor - PRM
The PRM equipment is the one to be used together with the PTD
Radio (UHF or VHF).
PRM components are a computer - PC or Notebook, depending on
if it should be carried close to the PTD or not - IBM compatible connected
to an IFR (RADIO INTERFACE).
Depending on the frequence to be used, differents IFR are provided.
Portable Reading Processor - PLP
The PLP is a hand portable computer that can be directly connected,
through its probe cable, to the UMPs, to collect data from them.
It loads routes to follow through its serial interface, downloading
later collected data.
