Abstract

The invention relates to a vibration sensing device, a data screening and direction judging method and a fan monitoring system. The fan vibration monitoring system comprises a fan multi-direction vibration sensor, a data transmission module, a fan main control PLC and a monitor analysis server, the fan multi-direction vibration sensor comprises the multi-direction vibration sensing device, the multi-direction vibration sensing device comprises an installation seat, the installation seat is provided with a swing block and is provided with a plurality of elastic beam pairs surrounding the swingblock, each elastic beam pair comprises two elastic beams, and each elastic beam is provided with a piezoelectric piece converting the deformation quantity into corresponding electrical signals. A threshold value is set, if each electrical signal data in any group is less than the threshold value, the group of electrical signal data is discarded; and if in any two adjacent groups of valid electrical signal data, only the electrical signal data corresponding to the two elastic beams of one of the elastic beam pairs is larger than the threshold value and generates the maximum value alternately,the direction which the elastic beam pair is in is the vibration direction.

Description

technical field [0001] The invention relates to a vibration sensing device, a data screening and direction judgment method, and a fan monitoring system, specifically a multi-directional vibration sensing device, a fan vibration monitoring system using the multi-directional vibration sensing device, data screening and vibration direction judgment method. Background technique [0002] As a clean and renewable new type of energy, wind power is developing rapidly, and the number of wind power generators (referred to as fans) has increased dramatically. As the key equipment of wind power generation, wind turbines will inevitably fail due to the complex operating environment. If it leads to abnormal shutdown, it will seriously affect the power generation efficiency. Therefore, it is very necessary and urgent to monitor the key operating signals of the fan and analyze and diagnose the fault of the fan. Fan faults mainly include electrical faults and mechanical faults. At present...
