The invention discloses a detection device for a bridge construction field structure deformation measurement sensor. The detection device is used for calibrating a deformation measurement sensor to bedetected. The detection device comprises a deformation mechanism, a loading mechanism and a data acquisition and analysis mechanism; the deformation mechanism comprises a deformation portion which can deform elastically, wherein the deformation portion is fixedly connected with two ends of the deformation measurement sensor to be detected; the loading mechanism is connected with the deformation mechanism and loads an acting force to the deformation portion so as to change the strain of the deformation portion; and the data acquisition and analysis mechanism is electrically connected with thedeformation measurement sensor to be detected, and obtains the strain of the deformation measurement sensor to be detected so as to complete the verification of the deformation measurement sensor to be detected. The detection device of the invention is specially used for the deformation measurement sensor. According to the detection device, the deformation of the deformation measurement sensor tobe detected is driven by the deformation of the deformation portion in the deformation mechanism; the data acquisition and analysis mechanism is used for acquiring the strain of the deformation measurement sensor to be detected; and therefore, the detection of the deformation measurement sensor to be detected is completed.

Description

technical field [0001] The invention relates to the field of sensor verification for structural health monitoring, in particular to a verification device and method for a structural deformation measurement sensor at a bridge construction site. Background technique [0002] In the field of bridge construction, with the advancement of information and communication technology, the control and management of the bridge construction process are becoming more and more intelligent. By using a large number of strain / displacement sensors, also known as deformation measurement sensors, to build intelligent construction sites, such as , installing vertical displacement sensors on the pile foundation to monitor the subsidence of the pile foundation remotely in real time, and installing strain sensors on the concrete box girder and steel box girder to monitor whether the construction stress exceeds the standard and achieve optimal control. [0003] However, in actual construction, there a...

Problems solved by technology

On the construction site, there is often a lack of standard loading instruments such as tensile testing machines (TMS) and corresponding verification devices, and the cost of sending them to other places for inspection is relatively high. The parameters provided by the manufacturer shall prevail, eliminating the need for verification before use, which buys hidden dangers for strict quality control and real-time and accurate monitoring of the structure during the construction process
