Using labview software to collect and process measurement data as partof development of systems of monitoring of bearing structures Применение labview для решения задач сбораи обработки данных измерений при разработкесистем мониторинга несущих конструкций

Present-day urban construction trends make buildings taller and the urban environment denser. These developments result in the growth of negative effects produced on existing structures. That’s why the monitoring of the technical condition of structures is of vital importance. Now the most efficient way of forecasting and preventing emergency situations consists in the installation of automated monitoring systems operating in continuous and periodic modes.Monitoring systems may comprise various sensors, devices and measurement elements. Any signal must be coordinated to make sure that the data are accurate and reliable. Moreover, the proposed system (or network) composed of various items of equipment (often produced by various manufacturers) demands appropriate integrated software. The database of LabVIEW drivers can be employed for this purpose.LabVIEW environment is applied for the measurement, testing and management of applications that constitute embedded programming tools needed to develop complex applications designated for computer-aided measurements and data processing. The library of drivers is employed to assure the availability of the most common types of interfaces, sensors and devices. If a user lacks a particular driver, it can be either integrated or developed. The authors have successfully collected and processed the data in the LabVIEW environment of a measurement system based on tensometric sensors attached to experimental items of equipment.Обоснована необходимость проведения автоматического мониторинга несущих конструкций, рассмотрен алгоритм сбора данных, представлены наиболее распространенные типы преобразователей.
