Description

The configuration “VIGENZONE” is based on the “Outdoor” model and is designed to meet the project requirements. The name comes from the site of the first intallation of this configuration (Vigenzone channel at Battaglia Terme, PD, Italy). The following figure describes the general architecture scheme.

Measuring Chain

The measuring chain is featured at each site of installation by the coupling of a measuring instrument dedicated to the hydrometrical level and a remote station both realized in compliance of the ACRONET Paradigm. The station hosts the Datalogger and rice-transmission of data functionalities. Data are transmitted directly through the GPRS module mounted in the station that has been programmed to send data to the ACRONETWORK infrastructure.

Devices and physical connections

The selected measuring instrument is the “ULG o03” from the ACROSENSOR family realized ad-hoc by integrating the transducer MB7563 from MaxBotix. Also in this case The Datalogger identified is the first device ACROSTATION family "O" (outdoor) issued for the occasion in release 02. In particular, it is the version "a" with metal box, internal GPRS antenna and standard power module (electronic board and battery backup). The power supply is furnished by the 10W solar panel the station is equipped with. The connection between the apparatuses is through the cable the measuring instrument is equipped with, with no remarkable limits for installation. The cable from the measuring instrument dedicated to the hydrometrical level can be directly connected to the serial port available in the ACROboard Station v01 r09 contained in the station.

Signals, data and protocols

The station receives the signal of the ACROSENSOR ULG o03 temperature-compensated (with an external thermometric sensor, namely MB7958 directly interfaced with the MB7563) generating with the same continuity the timeseries of data in native format. The firmware of the configurataion allows the metadating, the integration in time, and an early check of the accuracy by filtering eventual anomalous values.

Finally, the GPRS module transmits data according with the configuration file to the ACRONETWORK, in compliance with a simple HTTP not encripted protocol.

Power

Considering the solar radiation characteristics of the site, the power is supplied exclusively by the solar panel the station is equipped with.

Implementation

To make the configuration operational, the corresponding firmware (available at the bottom of this page) has to be installed, by using the appropriate programmer, in the MIC which is mounted on the ACROboard Station (equipping the station itself).

Similarly, at the first run, the base configuration file (available at the bottom of this page) that makes available the dialog with the ACRONETWORK infrastructure has to be uploaded.

Mounting and Installing

The assembly included a staff hosting the station and an outreach (both in galvanized iron) hosting the sensor. The fixing of the whole system will vary depending on the characteristics of the site and will be assessed at a later stage in relation to the availability of appropriate facilities (bridges, roads, dams, etc.).

Download Box

This area includes both the firmware dedicated to this specific Configuration and the basic implementation. You can use the firmware to manage the electronic side of the apparatuses, while the basic implementation is fundamental to run the system (define parameters, position, etc.). You can easily download them or find them in the GitHub repository.

Firmware

The Firmware is the program (sequence of instructions) that has to be integrated directly into the microcontroller placed on the ACROBoard selected for the Configuration. Its main purpose is to start the MIC as well as to interact with the other electronic items. Here you can find the .7z, the .zip folders and the link to the GitHub repository.

Basic Implementation

This set of files is coupled with the firmware and is fundamental to set specific operational parameters (position, frequency of logging, etc.).Here you can find the .7z, the .zip folders and the link to the GitHub repository.
