Problems solved by technology
When a system is connected to a large number of dynamic sensors, a large amount of data enters the server at the same time, and the network and data processing burden of the monitoring center will be very heavy, which will have a serious impact on the effectiveness of the early warning. It takes a long time to discover and call the police, which makes it impossible for the structure operation and maintenance personnel to deal with the abnormal state of the structure in time

The invention belongs to the technical field of structure real-time monitoring and relates to a vibration sensor for structure monitoring, in particular, a three-axis intelligent vibration sensor capable of realizing cooperative calculation. The three-axis intelligent vibration sensor capable of realizing cooperative calculation comprises a three-axis vibration sensor, an RC low-pass filter, a synchronous 3-channel analog-digital converter, a microprocessor unit, a communication module, a power source module, a FLASH memory and a data storage device; the microprocessor finishes a data acquisition, data characteristic value processing and data anomaly judgment cooperative processing function and interacts with an upper computer through a communication module; and the cooperative calculation of the microprocessor involves low-pass FIR filtering data noise reduction, characteristic value extraction, abnormal data removal, threshold exceeding warning and the like. According to the three-axis intelligent vibration sensor capable of realizing cooperative calculation of the invention, some operation processes and partial storage functions are distributed on the intelligent sensor, so that the calculation pressure of a server is reduced, requirements for a network are lowered, and fault processing tardy due to time delay caused by the overlarge computing pressure of the server is avoided.
Description
technical field [0001] The invention relates to the technical field of real-time monitoring of structures, and relates to a vibration sensor for structure monitoring, and relates to a three-axis intelligent vibration sensor capable of collaborative calculation. Background technique [0002] In the traditional structural health monitoring system, the vibration sensor nodes mainly complete the data collection and transmission functions, and all data processing and analysis are completed by the local monitoring center or remote monitoring center server. When a system is connected to a large number of dynamic sensors, a large amount of data enters the server at the same time, and the network and data processing burden of the monitoring center will be very heavy, which will have a serious impact on the effectiveness of early warning. It takes a long time to discover and call the police, which makes it impossible for structural operation and maintenance personnel to deal with abno...
