  • photovoltaic monitoring system

    Pragma Engineering has designed and developed in 2011 an Inverter DC Current Inputs Monitoring System for photovoltaic power plants.

    The monitoring system is able to acquire DC input currents of inverter devices included in a photovoltaic plant. In detail the monitoring system includes 8 current channels in order to acquire 4 DC lines for the master unit inverter and 4 DC lines for the slave unit inverter.

    The system has no views on local, but it can be queried via MODBUS TCP/IP protocol by Ethernet connection included in the controller module. The system has been configured with MODBUS parameters in order to permit requests by SCADA application supporting MODBUS communication protocol.

    Any fails of the transducers or of the system will be storage in the status discrete registers, in addition a led will be blinking in case of transducer fail or will be on in case of system fail (in normal operating mode the led will be off ).

  • Piazza del Campo Siena

    Starting from 1999 Pragma Engineering S.r.l. was charged by City of Siena to execute a monitoring intervention on tuff spreaded in Piazza del Campo when is running the Palio of Siena and this monitoring activity has the objective to improve safety conditions of jockeys and horses during the race.

    The main intend of the monitoring is the characterization of the soil (tuff) spreaded on the square when the race is running through detecting microclimatic parameters and physical features of the soil.

    The executed monitoring has allowed the creation of a wide and comprehensive database, that is needed to study and to implement improving actions for the sealing of soil especially in some critical points of the route.

    Executed actions :

    • Acquisition and analysing of data of the soil and climatic conditions of the square.
    • Supervision of the process of soil preparation, definition of soil preparation and eventually its revision.
    • Labs test in order to establish mechanical and physical features of the soil
    • Mechanical resistance tests of the soil locally executed.
    • Experimental activities of mechanical treatment of the soil.
