Demo timelapse concerning the demolition of Corso Grosseto overpass in Turin, started on May the 21st, 2018.

DAB+ Trasmission Tools

DAB (Digital Audio Broadcast) is one of the standard used to broadcast radio using digital encoding. Aside form audio, DAB permits the transmission of multimedia / applicative contents, such as images slideshow, traffic information, news and so on.

Audio encoding is based on MPEG-2 codec for legacy DAB and AAC+ for DAB+.
CSP has developed a system able to build a full DAB+ trasmission chian; basic components are:

AAC audio encoder (including insertion of ancillary data – slideshow and DLS)
ETI muxer
IQ modulator
RF modulator
a simple GUI to control all the components

A system of traffic flow monitoring based on video processing

Traffic Flow – Corso Castelfidardo

This system monitors traffic in urban context in real time and evaluates the vehicle flows. The video captured by a webcam is processed and the system is able to create dynamically a model of the roads (areas of the video frame where vehicle traffic is located) and calculate the vehicle traffic density for each flow.

Urban traffic monitoring is becoming increasingly important in order to optimize traffic, reduce travel times and reduce the environmental impact of traffic. Traditional techniques to count vehicles consist of installing mechanical or electrical sensors into the road pavement. These methods can be expensive and require physical changes (break pave, install sensors and repave the road). An alternative technique of traffic flow detection is based on video processing using computer vision algorithms. This technique is cheaper, more flexible and scalable than traditional ones.

A lamp measures the air quality

CSP has been developed a prototype unit for measuring the indoor air quality (IAQ). All sensors are integrated on a customized board and measurement are sent to a server using WiFi connection. A lamp has been suitably modified to accommodate inside the sensors and electronic boards.

Air pollution isn’t only an outdoor problem. The air in enclosed spaces, such as home, schools or workplaces, can also be polluted. In fact, some kinds of air pollution can be worse indoors than outdoors, such as tobacco smoke, mould, and chemicals released from synthetic fabrics, furnishings and household products. Wooden furniture and some paints or dyes for cloth can release toxic substances into the environment, such as formaldehyde.

The “lamp” measures Volatile Organic Compounds (VOCs) and formaldehyde (CH2O) levels and get a feedback lighting in different colors (green for clean air, yellow for warning level, red for polluted air). Other physical parameters are acquired such as temperature, humidity and illuminance.

MeteoIdro: a remote monitoring station using TETRA network

In this project an hydrometric station has been developed using high performance radar water level sensor and low power embedded systems. The entire system is powered by solar energy and uses a Texas Instruments MSP430 micro-controller for all operations.

Level water measurements are requested to sensor in polling mode, stored in a microSD and sent to remote site thanks to a TETRA wireless network. The station behaviour is based on profiles concept. Each profile defines the receiving and transmitting windows duration and the measurement period. Three profiles are implemented and the transition from one to another is based on river level variation.

A remote user can modify the station settings (like measurement, transmission and receiving periods) sending commands over the TETRA connection.

Gnuradio package is available on Odroid boards

gnuradio on odroid board

GNU Radio is a free software development toolkit that provides the signal processing runtime and processing blocks to implement software radios. GNU Radio SDR toolkit has been compiled to the ARM architecture and tested on Odroid-X, Odroid-X2 and Odroid-U2 boards running Linaro, a Linux distribution based on Ubuntu 12.11.

Air quality monitoring on GTT electric bus

The MASP (Monitoraggio Aree Sensibili e Protette) project was completed on February 28th 2013 and as final step it has been installed a mobile testbed on the electric bus of the company Gruppo Torinese Trasporti (GTT). This project aims at the development of an air quality monitoring system for sensible and protected areas. The MASP […]
