SOS Systems for Road Applications

SOS Systems

Electronic units specifically designed to handle emergency calls along highways.
The units, all IP65 and equipped with built-in self-diagnostics and centralized monitoring, are produced in a wide range of solutions to meet disparate application contexts.
In particular there are the following alternatives:

  • Communication media (copper cable, optical fiber, wireless);
  • Power source (remote powering via cable, mains, solar panels, POE);
  • Tecnology type (analogic, GSM, VoIP);
  • Functional options (webcam, actuators, sensors);
  • Installation environment (road side, galleries, viaducts).

VoIP Power Amplifier

Immagine STSIPA

The STSI_PA is a high performance Class D audio amplifier with integrated closed loop feedback technology (known as PurePath HD) and up to 120 W of power.
PurePath HD technology enables traditional AB-Amplifier performance levels (< 0.03% THD) while providing the power efficiency of traditional class D amplifiers.
The amplifier is designed to broadcast emergency messages in accordance with CEI EN60849 specifications for constant voltage loads (100 Vac) and low Amperes.
Available in different cases to suit your installation requirements, it incorporates advanced features such as:

  • WEB management interface;
  • Antilarsen Filter integrated;
  • Auto activation based on the level of the input signal (VOX function);
  • ALC (Automatic Level Control) can be enabled on all inputs;
  • Automatic generation of the warning signal (two-tone bell);
  • Day&Night Volume Control;
  • Broadcast of incoming VoIP messages (SIP phone integrated);
  • Support for automatic transmission of messages to a remote VoIP recorder;
  • Auto insertion of the ongoing recording signal;
  • Periodic diagnostic including the test of the speaker line.

CoaXPress Camera Sensor

Immagine CoaXPress

CoaXPress (CXP) is an asymmetric high speed serial communication standard over coaxial cable.
The most common application is to interface cameras to computers (via frame grabbers) on applications (such as machine vision) which involve automated acquisition and analysis of images.
A CoaXPress camera can be interfaced to a CoaXPress frame grabber by a single coaxial cable without an external power supply or extra cables for uplink communication to the camera.
The version CXP-6 supports up to 6.25 Gbps on cables of up to 68 m.
A low speed uplink channel, operating at 20.833 Mbit/s can be used for camera control or triggering.

Our product features:

  • Down stream speed up to 6.25 Gbps per lane
  • All the key functions integrated in a SOC based on Xilinx Kintex160 FPGA device
  • 1GbE (IEEE 802.3) channel
  • 1GB DDR3 memory
  • Supports both CIS and CCD sensors
  • mBlaze service processor
  • Real time Image correction
  • Integrated System Monitor and Debug
  • I/O opto isolated signals
  • Integrated Stack TCP/IP

Tunnel Navigator Safety System

Immagine TUNSS

System able to help the driver in situations where the visibility is low due to high density smoke, fog or smog.
Several technologies are integrated to detect objects in the worst conditions:

  • New generation radar (77GHz) based on Frequency Modulation Continuous Wave with 16 beams
  • 180° Laser Scan with 850nm wave length
  • Thermo Camera to detect objects depending on their temperature
  • Ultrasound sensors to detect lateral walls
  • A GPS receiver and an odometer to provide position information

Product Features:

  • Data fusion of different information coming from different sensors.
    All the data are placed considering the real position in a prospectic view.
  • The scene is build on a sequence of pictures pre-acquired that are automatically managed by the solution during the movement.
  • GPS information provides the global positioning through a map.
  • Acoustic signals alerts on the presence of objects
