Description

Technical Field

[0001] The utility model belongs to the technical field of bridge displacement monitoring instruments, and in particular relates to a bridge displacement monitoring instrument based on GNSS. Background Art

[0002] Bridges generally refer to structures erected over rivers, lakes, and seas to allow vehicles and pedestrians to pass smoothly. In order to adapt to the modern high-speed development of the transportation industry, bridges are also extended to buildings that are erected to cross mountain streams, poor geology, or meet other transportation needs to make passage more convenient. Bridges are generally composed of superstructures, substructures, supports, and ancillary structures. The superstructure, also known as the span structure, is the main structure for crossing obstacles; the substructure includes abutments, piers, and foundations; the supports are force transmission devices installed at the supporting locations of the span structure and piers or abutments; the ancillary structures refer to the bridgehead slabs, conical slope protection, revetments, diversion projects, etc.

[0003] Chinese patent application No. 2023216153247 discloses a bridge vibration displacement monitoring device, which relates to the field of displacement monitoring devices, including a rust-proof shell and a laser monitoring mechanism. The laser monitoring mechanism accurately locates any displacement caused by bridge vibration in three-dimensional space through three laser displacement sensors. The monitored signal is fed back to the integrated controller to accurately determine the degree of bridge vibration displacement through algorithm calculation. The gyroscope module can calibrate the change position of the monitoring device that produces relative displacement due to being fixed on the bridge. After the integrated controller algorithm corrects the detection parameters, the strong penetrating signal of the signal antenna can provide more stable information transmission, reducing data loss caused by information interaction with remote electronic devices. The rust-proof shell can ensure the safe use of internal electronic devices in the external rain and wind erosion environment. The drilling fixture is stably installed on the bridge position through large bolts, and the internal load-bearing plug-in board can extremely conveniently replace the electronic components therein.
