Real-time automatic monitoring system of bent slope pier beam displacement

Abstract

The invention discloses a real-time automatic monitoring system of bent slope pier beam displacement. The real-time automatic monitoring system comprises a first pier beam displacement detecting device used for detecting relative displacement between pier beams and converting the relative displacement to digital signals, a second pier beam displacement detecting device used for carrying out auxiliary verification on the first pier beam displacement detecting device, an image collecting device, a temperature sensor used for sensing temperature values, a signal processor and a power supply device, wherein the signal processor is used for temporarily storing the digital signals obtained through the first pier beam displacement detecting device, images collected by the image collecting device and the temperature values sensed by the temperature sensor and is used for transmitting signals to a remote monitoring center and a plurality of client sides, and the power supply device is used for supplying power for on-site terminals. By means of the real-time automatic monitoring system of bent slope pier beam displacement, real-time automatic monitoring on pier beam relative displacement, manual judging of expansion joint displacement conditions and support sliding states and verifying of data collected by the first pier beam displacement detecting device can be achieved.

Description

technical field [0001] The invention relates to the field of bridge pier beam displacement monitoring, in particular to a real-time automatic monitoring system for curved slope bridge pier beam displacement. Background technique [0002] The survey of a large number of curved bridges and slope bridges (collectively referred to as curved slope bridges) during the operation period shows that the pier, beam, support and expansion joints of the curved slope bridge will have interrelated diseases, such as: there will be damage between the beam body and the pier column. Abnormal displacement, mainly manifested as: excessive slippage, damage, or even failure of the support; abnormal displacement of the pier column, and in severe cases, circumferential cracks in the concrete within a certain height above the ground; abnormal sliding of the beam body to the width of the expansion joint Exceeding the limit or reaching the dead end, the expansion joints of the curved bridge are lateral...

Problems solved by technology

The manual detection method has various disadvantages such as laborious, labor-intensive, high cost, long construction period, affecting traffic, and requires professionals to carry out on-site measurement; while the displacement sensor method only monitors a single part, and the monitoring data is not comprehensive enough
