Product Description

HPQN-X Target free Multi point Bridge Deflectometer

This product adopts image speckle recognition technology and image blur recognition technology. There is no need for targets or other characteristic markers on site, and only one host can simultaneously measure dynamic deflection, static deflection, displacement, and vibration data from multiple points.
This product adopts advanced image speckle recognition and tracking technology and sub-pixel image algorithm. There is no need for targets or other artificial feature points on site. Only one host can simultaneously measure the multi-point dynamic and static deflection, displacement, impact coefficient, vibration frequency and other data of the structure. Meet the technical requirements for bridge dynamic parameter testing equipment in Appendix C of JTG/TJ21-01-2015 Load Test Code for Highway Bridges. This product is mainly used for measuring static and dynamic deflection, such as bridge completion acceptance and appraisal, special bridge inspection such as military floating bridges and suspension bridges, deformation and vibration displacement detection of dams and docks, and deformation and vibration displacement detection of large-span structures such as beams, columns, high-rise buildings, lifting machinery, drilling platforms, etc.

Product Function
This product adopts image speckle recognition technology and image blur recognition technology. There is no need for targets or other characteristic markers on site, and a single host can simultaneously measure dynamic deflection, static deflection, displacement, and vibration data from multiple points.

Product Features
1.This product has functions such as base point, full field calibration, light and shadow correction, full screen scanning, image denoising, and recording conditions, fully meeting the requirements of on-site applications;
2.Base point function: Based on the measurement data of this product as the spatial relative coordinates of the measured point, in order to eliminate external interference on the host installation end during on-site measurement, we specially set a reference point within the field of view of the host, and at the same time maintain that the reference point and the measured point are always within the field of view, which can effectively improve the accuracy of on-site measurement.
3.Recording conditions: On site measurement is recorded simultaneously, and data processing in the office allows for the addition of measurement points and supplementary measurement data. With the support of full field calibration function, the distance between measurement points is automatically generated, and supplementary measurement points do not need to return to the site for distance measurement;
4.Full field calibration: Given the distances between three measurement points and the host, the distances of other measurement points are automatically generated

Product characteristics
Target free non-contact: No need for target lights, natural feature points or manually marked points on the structure can be used as measurement points for measurement;
Multi point synchronous real-time measurement: 30-50 dynamic measurement points can be selected within the field of view, and all measurement points are measured and displayed in real-time without delay
Ultra long distance measurement: Through on-site testing of the Yangsi Port Yangtze River Bridge in Wuhan, it has been confirmed that the detection distance of this equipment can reach 1028 meters
Data collection module: recording working conditions, base point correction, measurement point retrieval
Data analysis module: equipped with intelligent filtering, full field calibration, recording conditions, light and shadow correction, full screen scanning, quality evaluation of measured points, image denoising, baseline self adjustment, base point function, system automatic calibration, real-time data display, automatic file storage, automatic analysis of maximum and minimum deflection values, mean measurement, impact coefficient, power spectrum, interval frequency, mean filtering, digital filtering, over limit warning, curve deletion, Excel generation, automatic generation of test reports and other functions.
