Acquisition power station / Hydrological station
ACQUISITION CENTRE or HYDROLOGICAL STATION CPL+
The power stations of acquisition PARATRONIC CPL+ are based on the experience acquired with the power stations of acquisition or hydrological stations CPL and Op@l. These three models of power stations of acquisition or hydrological stations having been either certified PLQ2000 by the INERIS, or validated by the INERIS.
The CPL+ acquisition plants or hydrological stations have been selected by the French Ministry of Ecology, Sustainable Development and Planning (MEDAD) for hydrology and flood monitoring and management.
They have the dual advantage of being one of the most efficient acquisition plants or hydrological stations on the market in terms of communication and reliability, while remaining a very low consumption acquisition plant or hydrological station.
The CPL+ hydrological power station or hydrological station is a modular hydrological power station or hydrological station essentially designed for hydrology, flood forecasting and flood management. It is capable of acquiring data from most sensors on the market(Paratronic, OTT, hydrologic, WTW, Polymetron, etc.). This makes it possible to envisage the evolution of the hydrological, flood warning or flood management site over time, without the addition of a particular sensor requiring any modification to the installation or replacement of the hydrological acquisition station or station.
For economic reasons, not all types of inputs present at the PLC+ data acquisition stations or hydrological stations are activated, but only those inputs/outputs defined for the needs of the hydrology, flood warning or flood management site for which the hydrological station is intended are functional.
The activation of the other inputs of the hydrological station or data acquisition unit can be done by simply entering an activation code (same principle as for a software license, for example).
In addition, the CPL+ hydrological power plant allows the transmission of the collected data by GSM modem or any other means of communication.

1 CHARACTERISTICS OF THE PLANT CPL+
Number of measurement channels of a hydrological acquisition plant or station:
The hydrological power station or hydrological station shown in the photo has a 4-20mA analog measurement channel. The number of measuring channels of the data acquisition unit or hydrological station can be increased by activating additional channels (1 second 4-20mA analog channel, 2 counting channels, 1 RS232 channel, 1 RS485 channel, 1 SDI12 channel without adding any hardware or input board or by adding additional input/output modules (analog [current or voltage or PT100] or digital (BCD, GRAY, Binary) or counting or serial link for intelligent sensor [RS232 or SDI-12 or RS 485]).
It should be noted that
- The RS485 link (if activated) accepts up to 9 sensors (or parameters) on a bus with the "J BUS" protocol. "(19 if no SDI12 channel is used) or (without activation) up to 9 additional input modules. This feature limits the number of extension channels required to receive multiple sensors or multi-parameters used, in particular, for water quality measurements (for example: WTW IQ sensor).
- The data acquisition unit or hydrological station can receive as many extension modules (one measurement channel per module) as the RS 485 bus supports (with the limits linked to the PLQ2000 protocol).
- The CPL+ data acquisition unit or hydrological station or its extensions are compatible with intelligent sensors:
Limit gauges:
- CRUZOE radar PARATRONIC J Bus
- LPN8 bubble to bubble Hydrologic,
- Nimbus, OTT bubble bubble
- Thalimedes, OTT
Quality :
- IQ sensor of WTW J Bus
- Monec D9100 from Polymetron J Bus
As the JBUS protocol over RS485 is a standard used by almost all manufacturers of sensors and/or PLCs, the number of sensors compatible with the PLC+ data acquisition unit or hydrological station is almost infinite. The above list is therefore far from being exhaustive.
- CPL+ also manages thresholds, alarms and the control of automated systems or samplers.

2 MEMORIZATION AND DATA STORAGE
The acquisition station or hydrological station CPL+ has a memory capacity of 110,000 measurements and also saves events related to operating modes and communications.
The connection to the CPL+ data acquisition unit or hydrological station does not require any specific software. A simple web browser allows the parameter setting, data retrieval and curve plotting.
The recovery of the measurements stored in the CPL+ data acquisition unit or hydrological station is carried out using the PLQ2000 protocol, recognised by the Sircade(Aquasys/Alcir), SIGMA II(PARATRONIC), NOE2000(centralp), Syrene, Cristal software programs ....
See our dedicated website: www.paratronic.info
3 COMMUNICATION WITH THE CENTRAL OFFICE CPL+
The CPL+ data acquisition unit or hydrological station can be configured and discharged locally or remotely via PSTN, GSM, Radio, Satellite, Minitel, Serial ports, Bluetooth, etc.
The modem shown in the picture is an ERCO GENER GENPRO20E modem associated with a DATA subscription. The GENPRO20E model is the GSM modem used on the majority of the sites of flood announcements or general hydrology of the ministry (MEDAD).
However, PLC+ data acquisition units or hydrological stations are compatible with most GSM/GPRS and PSTN modems on the market.
4 CONSUMPTION AND AUTONOMY
The autonomous power supply modes that can be supported by the PLC+ data acquisition unit or hydrological station are: battery, solar panel, cells, fuel cells or any other 12Vdc power source. The autonomy obtained depends directly on the characteristics of the power source, the number and type of sensors used, the acquisition time step and the transmission mode chosen for the hydrology, flood warning or flood management site.
For hydrological, flood warning or flood management sites that do not have mains power, the operation of the hydrological acquisition station or station is compatible with an autonomous power source (batteries, solar panel, etc.).
For hydrological, flood warning or flood management sites with a 230V power supply, the low consumption of the data acquisition or hydrological station allows an autonomy of several days, or several months, on battery power in case of power failure.
The acquisition station or hydrological station CPL+ is usually supplied by a stand-alone energy generating unit consisting of a solar panel and a battery coupled to a charge regulator.
The PLC+ hydrological power plant or hydrological station integrates a set of functionalities aimed at a fine management of consumption. This data acquisition unit or hydrological station can act on its own consumption as well as that of its peripherals (sensors, modem, etc.). This management is conditioned by the cycle linked to the acquisition period and by asynchronous events (incoming call, local terminal connection, etc.) to which the hydrological, flood warning or flood management site may be subjected.
From a consumption standpoint, the power plant or hydrological station has two main states: an active mode and a standby mode. The standby mode is the state in which the power plant or hydrological station has minimum consumption. When the acquisition station or hydrological station has no tasks to process and, if its configuration allows it, it automatically switches to this mode. The return to the active mode is conditioned by the following events:
Incoming call,
Acquisition on a measurement channel,
Press a button on the integrated interface,
Connecting the local terminal,
Change of state of the logic inputs.
The data acquisition unit or hydrological station manages the power supply to the sensors by individual parameterization. The power supply of the serial links and the modem link is also controlled by parameter setting of the data acquisition unit or hydrological station.
Consumption characteristics of the power plant or CPL+ hydrological station :
Active mode: 62 mA,
Sleep mode: 0.7 mA,
20 mA serial link.
Example of autonomy :
The autonomy of a hydrological, flood warning or flood management site depends both on the consumption of the hydrological acquisition station or station, the number and type of sensors, the nature of the modems, the frequency and depth of the collections and the nature and capacity of the energy source.
Configuration used for the calculations:
Data acquisition unit or hydrological station CPL+ connected to an analogue water level sensor of type RADAR CR420 (12mA on average, total power supply time of the sensor: 5s),
Periods of acquisition and storage in sliding file: 15 minutes,
Daily GSM communication (PROGEN20e from ERCO-GENER) with the SIGMA II collection system.
In this configuration, the photovoltaic unit shown above allows a completely autonomous operation and even allows an autonomy of 21 days in total absence of sunlight. This includes the possibility of generating five GSM communications per day over forty-eight hours in times of crisis.
In any case, the SIGMA II supervisor will be informed of the low battery charge level of the hydrology, flood warning or flood management site.
