The present invention provides a bridge structure health monitoring system having a low cost and a good convenience. The present invention includes a power source managing power source, a data collecting unit, a data processing unit, and a data transmitting unit; and the structural key points thereof are: the power source managing power source is respectively connected to the data collecting unit, the data processing unit, and the data transmitting unit; the data collecting unit includes a pressure sensor and an accelerated speed sensor; the data processing unit includes an AM29F032E chip, an RAMCY62512 chip, and an MSF43CF14S chip; and the data collecting unit, the data processing unit, and the data transmitting unit are successively connected.

Description

technical field [0001] The invention belongs to the technical field of bridge monitoring, in particular to a bridge structure health monitoring system. Background technique [0002] Structural health monitoring system is derived from bionics and is the common product of interdisciplinary interaction. The traditional way to achieve monitoring is based on wired sensor data acquisition, but this has many important defects: the most important thing is that the sensor equipment must be connected to the central data acquisition unit through cables, so there must be a large number of cables for laying, and this is Expensive and time-consuming; Another point is that the cables are pre-embedded in the structural layer to reduce the cost of testing, but this increases the workload of contractors and engineering designers, and cable damage is also a big problem, which is not an optimal solution. So the wireless form is the direction of the next step, and it is inevitable. Therefore, ...
