Abstract: Results of analysis of recent accidents in public buildings are presented. It is shown that construction state identification systems are integral part of public and local warning and security systems. Structure of construction of state identification system is proposed and analysed. It is established that in order to ensure wide usage of such systems it is necessary to solve some scientific problems. Solution for multipoint measurement of strain as one of the most important parameter for construction state identification is proposed. It is shown that measurements of strain by using closed-loop self-balancing system ensure necessary resolution with high accuracy and can be used in multipoint measurements. Two closed-loop self-balancing systems using digitally balanced Wheatstone bridge and balancing of currents are presented and analysed.
