The TULCOEMPA project is based on the Swiss-Polish cooperation between the Lodz University of Technology (PL) and Empa in research and development of the innovative methods for monitoring in the civil engineering infrastructure.
This multidisciplinary project lasting from 2011 to 2015, focuses sustainable development of civil engineering activities on increasing the carrying capacity of bridges and their long-life monitoring with advanced wireless systems.
Multipurpose program of the project covers two areas: civil engineering, as a component of the environmental infrastructure in general and structural heath monitoring of buildings as a part of the information and communication technologies.
Combining activities of the two research fields is the aim of development of innovative civil engineering (CE) techniques, on the one hand, and modern systems of remote monitoring systems (ICT), on the other hand.
The first area of activities will be expressed by the pioneer worldwide usage of the innovative strengthening system of selected bridge (located in Szczercowska Wieś) using unanchored prestressed carbon fiber reinforced polymer (CFRP) laminates, whilst the area of ICT will ensure the effectiveness of this strengthening technique by the long-term monitoring of the facility and any additional environmental influences (temperature and humidity) as well as static and dynamic effects on the object.
Broad in scope and content monitoring will include multi-point measuring system composed of the networks of sensors, transducers, nodal points, a base station to the GSM wireless communications and computer system for collecting, processing and data coding.
The measuring system recording the static and dynamic deformation and environmental conditions form dozens of sensors due to the large amount of data requires the selection of measurement data and collaboration with the specialized system of recognition and identifying the mass, velocity and number of vehicles. The development of an innovative system for identity heavy vehicles will reduce the number of unnecessary data and monitoring system to run only during the passage of the vehicle, which significantly reduces power consumption of energy. Individual and specialized software system will enable the wireless control and recording of measurements of selected nodal point and the processing of measurement results in order to detect alarming systems.
Multipurpose and independence of this innovative monitoring system will be to guaranteed by batteries and energy harvesting from solar cells, which is another pioneering solution in the applied project.
Direct researcher results show their importance in scientific, industrial and social dimension.
-commercialization of the innovative technologies and services that increases the competitiveness of the national and International industry
-support the transformation and modernization of industry in the traditional building sector
-cost reduction of monitoring by easily deployable wireless monitoring
-increase of the social awareness of the alarming states and safety of the building maintenance
-extension of serviceability time the strengthened structures reduces costs of their replacement by new ones
-proper maintenance of the civil engineering infrastructure using innovative monitoring systems influence on the quality and building safety
-creates new skilled job opportunities for qualified technical personnel
Awareness increase in the strengthened and monitored bridges serviceability decreases economical and environmental consequences of their replacement, both in the financial,
energy and material resources, thus resulting in broad environmental protection.
