Method for preliminary selection by weight and assessment of technical condition of engineering structures

摘要

a pre selection of weight and condition assessment of bridge engineering, especially characterised by the fact that in the road placed set of deformation sensors (1) connected by wire or wirelessly to a control system of belt drogow a camera (5) is placed which is connected by wire or wirelessly to a control system.measured value emphasis on individual sensors (1) and the time interval between successive maksimami pressure with each sensor (1), the camera (5) placed on a road picture face of vehicleidentifies automatically vehicle on the basis of his images taken by the camera (5) and the result of identification is recorded in the data file identifying the vehicle; with maximum pressure values and time intervals between successive maksimami designates the number of axles of the vehicle and calculated value of pressure at each axle of the vehicle.the difference between the pressure on each axle and the threshold value and the vehicle speed, then the calculated values are assigned to a data file identifying the vehicle, then chooses the vehicles for which the difference between the value of the pressure value calculated in each axis and threshold value is greater than zero.
