Embodiment Construction
[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0034] It should be understood that although terms such as "first" and "second" may be used herein to describe various elements, these elements should not be limited by these terms. These terms are only used to distinguish one element from another. Thus, a "first" element discussed below could also be termed a "second" element without departing from the teachings of the present invention. It will be understood that when an element is referred to as being "con...

The invention discloses an automatic real-time monitoring system for the displacement of slope bridge pier beams. The system comprises a first bridge pier beam displacement detector for detecting the relative displacement between bridge pier beams and converting the relative displacement into a digital signal, a second bridge pier beam displacement detector for performing auxiliary verification on the relative displacement, obtained by the first bridge pier beam displacement detector, between the bridge pier beams, an image collector for collecting images, a temperature sensor for sensing a temperature value, and a signal processor for temporarily storing the digital signal obtained by the first bridge pier beam displacement detector, the image collected by the image collector and the temperature value sensed by the temperature sensor and transmitting the signal to a remote monitoring center. The automatic real-time monitoring system for the displacement of the slope bridge pier beams can perform real-time automatic monitoring on the relative displacement of the bridge pier beams, performs manual judgment on the displacement condition of telescopic seams and the sliding state of a support base, and realizes the verification function on the data collected by the first bridge pier beam displacement detector.
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...
