Abstract

The invention provides a method and a device for calibration of photoelectric bridge deflection meters. The device comprises a measurement mainframe, a moving module and an automatic leveling module. The measurement mainframe is used for calculating calibration data of a to-be-calibrated deflection meter on the basis of set reference data and measurement data of the to-be-calibrated deflection meter. The moving module is connected with the measurement mainframe and vertically moving relative to the horizontal plane to enable deflection measurement of the to-be-calibrated deflection meter on the basis of control signals obtained from the reference data processed by the measurement mainframe. The moving module is arranged on the automatic leveling module which is connected with the measurement mainframe, and the automatic leveling module is controlled by the measurement mainframe to realize automatic leveling. By the method and the device for calibration of the photoelectric bridge deflection meters, calibration of static deflection and dynamic deflection of the photoelectric bridge deflection meters can be realized.

Description

technical field [0001] The invention belongs to the technical field of bridge detection, and in particular relates to a photoelectric bridge deflection meter calibration device and method. Background technique [0002] With the rapid development of China's economy, there has been a trend of heavy-duty, high-speed, and large-flow modern transportation structures in transportation, and the proportion of road transportation in the entire transportation system is increasing. Bridges are the throat of roads. Therefore, road transportation has put forward higher requirements on the structural performance and service quality of existing bridges (ie old bridges) and new bridges. In order to test the quality of newly built bridges and ensure the safety of bridge structures in service, on-site load tests and health monitoring of bridges are indispensable. [0003] There are two types of bridge load tests: static load test and dynamic load test. The static load test is to observe the...
