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. A new method for measurement of construction strain is presented. It is based on evaluation of small changes of resistance with balancing currents. Measurements methods of these days are listed and their main advantages are discussed. Structure of strain gauge and formulas for calculating code of resistance changes is presented. Computerized and experimental models are made.
