Abstract

The invention discloses a bridge support state monitoring device and method, and belongs to the technical field of bridge monitoring, the device comprises an MCU processor, an analog quantity input module, a digital quantity input module, an RS485 input communication module and an RS485 output communication module, the analog quantity input module, the digital quantity input module, the RS485 input communication module and the RS485 output communication module are respectively connected with the MCU processor, an RS485 bus is accessed to communicate with an upper computer, and the upper computer is connected with the MCU processor. Bridge support data collected by different types of sensors are forwarded to the upper computer for subsequent analysis and processing of the upper computer, labor intensity is reduced, data caching and abnormal data reporting are effectively guaranteed, and therefore monitoring of the state of the bridge support with good real-time performance is achieved.

Description

technical field [0001] The invention relates to the technical field of bridge monitoring, and more specifically relates to a bridge support state monitoring device and method. Background technique [0002] In bridge construction projects, errors in engineering structure design, construction and construction and defects in engineering materials are unavoidable. In order to ensure the safety of bridges and prolong the service life of bridges, bridge health monitoring is particularly important. Nowadays, bridge monitoring usually adopts manual periodic monitoring or wired monitoring system. Among them, foundation pile hole detection technology can be used to obtain parameters such as hole diameter, hole bottom sediment, inclination, depth, etc. Static load detection technology can detect deflection (structure), settlement (support and abutment), support degree (structure) , cracks (bridge deck) and other indicators. [0003] However, there is a problem of strong subjectivity ...
