Abstract

The invention provides a novel sensor based on displacement amplifying device automatic identification technology. The sensor can be applied for shaft force measurement in civil engineering monitoring field. The sensor comprises a mechanical part and a computer vision system. The mechanical part comprises an end cover, a fine tuning pedestal, a fine tuning rod, an elastic body, a displacement amplifying device clamp, a displacement amplifying device, a fixed base plate and a tubular body. The displacement amplifying device is fixed in the elastic body via the displacement amplifying device clamp. The computer vision system is arranged in the tubular body which is connected with the elastic body. When the elastic body bears axial pressure and deforms, a pointer of the displacement amplifying device will deflect, and after processing of the computer vision system, deflection quantity of the elastic body can be obtained. By use of the deformation quantity of the elastic boy, the value of the shaft force borne by the whole sensor can be calculated. The sensor is high in precision, convenient to install and maintain, free form interference of electromagnet field, highly reliable and long in service lifetime.

Description

technical field [0001] The invention belongs to the technical field of detection and relates to civil engineering measurement, in particular to a sensor based on the automatic identification technology of a displacement amplification device. Background technique [0002] At present, in pressure detection, the most widely used pressure sensors are as follows: strain gauge sensor, piezoresistive pressure sensor, piezoelectric sensor, capacitive pressure sensor, Hall pressure gauge. Among them, strain gauge, piezoresistive and Hall pressure sensors are easily affected by temperature; piezoelectric sensors are not suitable for static pressure measurement and are susceptible to electromagnetic interference; capacitive sensor output is nonlinear, parasitic capacitance and distributed capacitance Accuracy is greatly affected. [0003] Since the vibrating wire sensor was invented in the last century, it has been widely used in the safety monitoring of bridges, dams, tunnels and oth...
