SECURITY

SITE designs and develops the RENO System (Recognition Echoes Near Object), programmed to monitor the stability and security of bridges, providing continuous or on-demand reporting.
 

Reno System

Scouring, the erosion of the river bed around bridge piers, is a consequence of the water turbulences during floods which interfere with the piers, and represents one of the main causes of structural collapses and bridges unavailability to traffic.
advantages
RENO System, thanks to dynamic monitoring, allows to:
  • evaluate bridge safety related to the risk of pier scouring
  • evaluate river bed condition related to the risk of flooding
  • evaluate bridge conditions in order to determine the possible closure to the traffic

Reno System TD

Components
  • Reno FD probe
  • hydrometer
  • micropile installed into the rived bed
The Reno FD probe the system key point, is installed on the top of the micropile installed upstream the pier to keep monitored. It consists of:
  • accelerometer
  • data acquisition module
  • I/O GSM-GPRS modem
  • hermohygrometer
  • inclinometer
The hydrometer is installed on the bridge, using a cantilever support bracket. The micropile is made of S.
Technical specifications
Technical specifications
  • Diameter 22 cm
  • Weight 12 kg
  • Power supply Min 15 V ca., 12 V cc
  • Solar panel typology (if powered by panel) Min 40 W
  • Wireless data transmission GSM/GPRS
Measurement ranges
  • Scouring 0-8 m, precision ±0.2 m
  • Temperature -30°C +80°C resolution ±0.1 °C
  • Hydrometric level 0-16 m resolution ±0.1 m
  • Relative humidity 0-100 % resolution 1 %
  • Inclination (of the sensor, compared to the vertical) 0-35 ° resolution ±0.1 °
FUNTIONAL DESCRIPTION
The system measures the scouring level from the dynamic response of the micropile exposed to the fluid action, and supplies some auxiliary data such as:
  • micropile inclination
  • water level
  • ambient temperature
  • air relative humidity
TECHNOLOGICAL DESCRIPTION
RENO System detects the accelerations produced by the action of the current on the micropile. These data are transmitted to the remote control centre, which processes them using a proprietary algorithm. The remote control centre, consisting of dedicated servers, can be located wherever it can be reached by the GSM signal and connected to the internet; electronic control and computing unit is equipped with a TX/RX card able to collect data coming from the bridge. Based on the scouring intensity, the system is able to calibrate time acquisition and its switch-off, in order to observe the phenomenon progress more accurately. The procedure is completely automatic. System settings and configurations can be varied from a remote site by means of GSM connection.

    • Relative humidity 0-100 %, resolution 1 %
    FUNTIONAL DESCRIPTION
    The system measures the scouring level evaluating the reflections from the river bed to the ultrasounds generated by the sensors and supplies auxiliary data such as:
    • hydrometric level
    • ambient temperature
    • air relative humidity
    TECHNOLOGICAL DESCRIPTION
    RENO TD system is normally switched-off. Data acquisition starts in the following situations:
    • in normal weather conditions, to detect data like temperature and humidity
    • in case of weather crisis, to monitor the height of the river bed at regular intervals set by the user, together with the alarm thresholds
    The remote control centre, consisting of dedicated servers, can be located wherever it can be reached by the GSM signal and connected to the internet; electronic control and computing unit is equipped with a TX/RX card able to collect data coming from the bridge. System settings and configurations can be varied from a remote site by means of GSM connection.
