Data Collecting Platforms PM 46
Data Collecting Platforms PM 46: Hardware Description
collecting platforms PM46 are manufactured according with specifications
requested by MED-HYCOS project. Designed for remote monitoring, the platform
is able to accommodate 17 sensors, in a range of temperatures from -20°C
Basic measurements of water
level, rainfall, water temperature and air temperature
Storage of elaborated data on
waterproof removable cartridge flash type EEPROM, without connection,
METEOSAT radio transmission
(MED-HYCOS) and also possibility to use GOES/GMS, ARGOS, INMARSAT or modem.
self power supply,
Easy installation and maintenance,
Possible evolution on site :
interfacing of new sensors, processing...,
Additional capacities for meteorology
or water quality monitoring.
Designing of platform
Modular device allowing interfacing
of any type of sensors,
Double housing unit : ventilated
external box, watertight internal box including electronics,
External box made of polyester-glass
fibre resisting to severe environmental conditions (humidity, salinity;,
standard and evolutionary user's
Configuration of the platform
and set up of the measurement channels with interface keyboard - LCD screen,
Verification and permanent display
in-situ of housekeeping variables.
Data acquisition electronics
Simple and secured by using
tested components (built on a micro-controler INTEL 80C186).
Self powered supply by solar
panel with regulator on-board and a lead type battery.
Very low consumption obtained
by using 3 volts Cmos components .
Sampling interval programmable
individually for each sensor from 1 minute to 60 minutes ,
Fixing of zero of scale possible
for water level,
Pre-processing operations (minimal,
maxima, means, filtering or anything else) programmable on interval times
from 1, 6, 15, 30 minutes, 1, 3, 6, 12 or 24 hours,
Data formatting for transmission,
Data recording on-site using
a solid state removable card and depending on minimum threshold variation
(or other criteria) programmable for each sensor.
2 intelligent digital inputs
for water level sensors ( SDI12, RS232/V28, CCI or TTL),
4 counting inputs (2 for tipping
bucket rain gauges, 2 else for frequency measures),
12 analogue inputs (3 for wind,
9 for temperatures, hygrometry, atmospheric pressure, solar radiation and
any sensors with low or high voltage output, current measure output or
3 digital communications output/input:
1 for METEOSAT (V28), 1 for a modem (V28), 1 for test and maintenance,
Possibility (on request) of
two code gray inputs
Data recording on removable
memory card : solid state waterproof module, contact less (induction link),
capacity of 128 Koctets or 1 Megaoctet.
Data formatting depending on
Possibility to use transmitters
UHF88 ARGOS, BM18 METEOSAT or SATURN Cof ABB for INMARSAT C. METEOSAT transmitter
self-synchronisation by GPS, allowing automatic synchronization of the
possibility (remote control and maintenance) with INMARSAT-C,
Coupling for telephone modem
or VHF radio.
Self powered supply
Nominal power supply : 12 V
Solar panel 20 Watts / waterproof
lead battery 12 Volts / 26 Ah.
