Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of sensors, and in particular relates to a wireless vibration sensor based on the Star Flash SLE technology. Background Art
[0002] StarShine SLE technology is a wireless short-range communication protocol architecture. The wireless short-range access technologies that this protocol architecture can provide include StarShine basic access technology and StarShine low-power access technology. StarShine solves the communication needs of high-speed, low-latency and high-reliability between IoT devices, especially in terms of low energy consumption, fast speed and low latency.
[0003] Large-scale mechanical equipment has a large number of rotating mechanical parts inside, and they are distributed in various locations throughout the equipment. Failure of some important rotating parts will immediately cause the entire mechanical equipment to fail to operate normally, and may even cause serious accidents and severe economic losses. When an abnormal situation occurs during the operation of the machine, the vibration will generally increase and change. Usually, based on the results of measuring, processing, analyzing and identifying the vibration signal, the cause, location and degree of deterioration of the fault can be diagnosed without stopping or disassembling the equipment. Although the vibration problem of rotating machinery is often caused by a combination of multiple factors, various types of vibration still have their inherent properties. In addition to the differences in the vibration process and vibration characteristics, the vibration spectrum can usually reflect the nature of the vibration more completely. The cause of the vibration abnormality can be found based on the measured vibration spectrum distribution.
[0004] At present, vibration data collection mostly uses vibration meters, inspection instruments, smart phones, tablets and sensors. However, in factories, one hand is often required to hold the sensor and the other hand to hold the smart phone. At this time, it is difficult to operate the equipment during high-altitude operations and input information, which is difficult and inefficient. Utility Model Content
