Thanks to its innovation and development capabilities acquired in the aerospace field, TSD can support Industries working in different fields in the definition and development of  products from the conceptual design to the engineering  prototype realization. The most important developed products are:

 •  Data Acquisition Unit (Unità Acquisizione Dati UAD)
 •  Data Acquisition Unit 2.5 (Unità Acquisizione Dati 2.5, UAD 2.5)
 •  WASP (Web Application Service Provider)


UAD is remarkable example of  product entirely developed for a specific field. It is an advanced system for the acquisition of geological and infrastractural environment data of the  railways for high speed trains (Prime contractor Strago, final Customer Italfer)

The main features of the UAD are:

 •  High resolution data acquisition (20 bit)
 •  Processing and storage in loco of the acquired data
 •  Remote and local control of the data acquisition system
 •  Modular and configurable architecture
 •  High reliability

System Architecture
The UAD overall architecture comprises the following items:

URGD board, based on Atmel 80C32 microcontroller, is in charge of data processing and storage; it also implements the communication interfaces of the entire UAD. For high data flow application the usage of a DSP is foreseen (ADSP-2185 by Analog Devices).
HRDA (High Resolution Data Acquisition) boards, that implement a 20 bit analog to digital conversion of the signals coming from the sensors. The communication link between the HRDA and the URGD is composed by a full-duplex digital serial link with a programmable bit-rate (up to 2 Mbit/s).

POWER SUPPLY SECTION, composed by a backup battery and an electronic circuit for the battery charging and the system partial turning-off, during the inactivity periods.   

UAD 2.5

UAD2.5 (Unità di Acquisizione Dati, ver. 2.5) represents an evolution of the UAD. It is a system for the acquisition of geological and infrastractural environment data (Prime contractor Strago)

The purpose of the INVISS project (Innovative Network VIdeo  Surveillance System) is to realize an integrated and smart video-surveillance system. The INVISS will join, in a single product several features like advanced compression techniques, high storage capabilities at high data rate and very compact architecture with high performances.

The INVISS is composed of three modules:

  • a video camera comprising
    • the Mass Storage Module (MSM) handling the I/F towards a solid state memory (capacity 16GBytes) used to store the acquired video images after their real time compression at low compression factor by an Embedded Video Encoder
    • a Processing Unit (PU) hosting the motion detection, audio detection and alarm detection algorithms and used to perform "lossless" and "visually-lossless" compression of video data; the unit will be also capable to perform the compression of Region of Interest of the  images in a MPEG4 compatible format and to send these compressed data on ethernet network
  • an I/O module able to handle ethernet I/F (used both for data transmission and camera powering according to PoE standard), USB I/F and further I/O devices
  • a Wireless Communication & Control Module in charge of handling all wireless I/Fs of the system (i.e. WiFi for data transmission/reception towards wireless router/switch, GPRS I/F for SMS transmission, "Satellite" I/F used to transmit data also in extreme conditions when the traditional communication links are not available)
