Real-time monitoring system for bottom surface of bridge

Abstract

The invention provides a real-time monitoring system for a bottom surface of a bridge. The real-time monitoring system comprises a rail mechanism which is arranged at the bottom surface of the bridge, and a detection mechanism which is arranged on the rail mechanism and is used for detecting the actual condition of the bottom surface of the bridge; a main rail is arranged on the bottom surface of the bridge and a secondary rail is arranged at the lower part of a bridge opening and the detection mechanism arranged on the main rail is used for bearing a secondary detection mechanism; the arranged main rail is higher than the vertical height of the secondary rail; the detection mechanism moves on the main rail and the secondary detection mechanism is laid on the secondary rail along the movement direction of the main rail, so that a monitoring test is carried out in all directions and a phenomenon that a detection period is long is avoided; and acquired data information is returned back to a central control room and is subjected to rapid comparison and analysis, so that the problems of the bottom of the bridge are rapidly compared.

Description

technical field [0001] The invention relates to the technical field of bridge detection devices, in particular to a real-time monitoring system for the bottom surface of a bridge. Background technique [0002] Bridge deformation monitoring is of great significance for mastering the health of bridges and ensuring bridge safety. At present, the commonly used equipment for bridge deformation monitoring are: conventional ground measurement equipment, GPS bridge displacement detection equipment, and radar deformation measurement equipment; Timely response and treatment will result in huge property losses and heavy casualties, so we need to monitor the deformation of the bridge in real time to achieve the purpose of early treatment.

At present, the commonly used equipment for bridge deformation monitoring are: conventional ground measurement equipment, GPS bridge displacement detection equipment, and radar deformation measurement equipment; Timely response and treatment will result in huge property losses and heavy casualties, so we need to monitor the deformation of the bridge in real time to achieve the purpose of early treatment

[0003] A real-time monitoring system for bridge deformation is disclosed in the publication number CN 105890663 A. The invention includes a monitoring room and a bridge deck; the bottom of the bridge deck is connected with a bridge deck support beam; the two ends of the bridge deck support beam bottom are connected with bridge piers; One side of the bridge deck is equipped with bridge deck monitoring point sensors; the monitoring room is associated with the bridge deck monitoring point sensors; both sides of the bridge deck are provided with flanges; the flanges are in a horizontal state; the inside of the monitoring room is equipped with a data processor; An evaluation worker is set on one side of the data processor; the top surface of the evaluation worker is connected to a console; bridge monitoring point sensors are set at both ends of the front of the bridge deck support beam; bridge pier monitoring point sensors are set on the side of the bridge pier near the bottom ;The side of the other pier near the bottom is equipped with a displacement gauge; although this structure has obtained a good detection effect, it cannot detect the interior and all-round detection, which makes it prone to mistakes

[0004] In the publication number CN 105973452 A, a remote bridge vibration monitoring system includes a laser transmitter, an optical fiber coupler, an optical fiber, a stepping motor, a plane mirror, an optical fiber collimator, a photoelectric detector and a signal transmission module, and a laser transmitter The emitted laser light is dispersed into multiple laser beams after passing through the fiber coupler. The first laser beam is irradiated on the rotatable plane mirror through the optical fiber, and the laser beam is reflected on the plane mirror. The laser light is sent to multiple photodetectors respectively through the optical fiber; the photodetector also receives the scattered signal of the laser light on the bottom surface of the bridge and sends the signal together with the laser signal received from the optical fiber to the signal sending module; To obtain the information of the bridge, but it has not realized the all-round detection of the bridge, so it is also prone to mistakes.
