[Abstract]:Vibration detection analyzer is one of the most basic and commonly used instruments in mechanical industry. It is mainly used to judge the operation of mechanical equipment and widely used in coal mines and manufacturing industries. Hand-held vibration detector is a miniaturized portable instrument mainly used in field and field measurement with high performance and price ratio. As a special computer system which can be reduced by both hardware and software, embedded system has the characteristics of high performance, miniaturization, low power consumption and low cost, which can meet the design requirements of hand-held vibration detector. With the development of mechanical industry, the requirement of mechanical vibration detector is more and more high. Aiming at the disadvantages of traditional vibration detector, such as poor real time, not easy to carry and large power consumption, this paper presents a vibration detector based on Atom and ARM. It is an on-line real-time detection system with the advantages of good real-time, easy to carry and low power consumption. The main structure includes sensors, ARM platform and Atom510 platform. The latest ATOM platform not only has low power consumption, but also can transmit data online with ARM platform. It can realize remote control, and the system is extensible. Its structure is that sensors are connected to ARM platform, ARM platform is connected to Atom510 platform. The sensor converts the vibration signal of the device into electric signal, and the command is sent by the ATOM platform to control the Ar / D module on the ARM platform to sample the converted electrical signal, and the signal is transmitted to the Atom510 platform through the control of the ARM processor. The Atom510 platform carries on the spectrum analysis to the received data, and displays on the graphical interface. The system adopts the latest ATOM510 platform and ARM platform to improve the computing performance, reduce the power consumption, and reduce the size of the portable space, and further improve the algorithm. Most of the traditional vibration detectors use the FFT algorithm, which has a large amount of calculation, which affects the real-time performance. This system uses the sliding FFT algorithm to reduce the amount of calculation, improve the real-time performance, and reduce the storage space of the system.
