Abstract: To address the potential damage to important factory equipment during transportation, this paper designs a wireless vibration signal acquisition and storage system based on an STM32F103+FPGA framework, which can be used for real-time monitoring of abnormal vibrations during the transportation of important equipment. First, the system is rigidly attached to the equipment being transported. Vibration data is obtained through a three-axis vibration sensor. The FPGA collects and stores the data. The STM32 sends the data to the corresponding host computer via a wireless module, where corresponding vibration parameters are judged to determine the transportation status of the equipment. Vibration table experiments and actual collision experiment results prove that this wireless three-axis vibration signal acquisition and storage system can be applied to abnormal vibration monitoring of transported equipment, and features easy installation, fast, and accurate measurement.

0 Introduction

Vibration is a ubiquitous phenomenon. Although equipment such as vibrating screens [1] and road rollers, which utilize vibration characteristics, bring many conveniences to daily life, more often, vibration can damage mechanical equipment [2]. For example, abnormal vibrations generated during transportation often jeopardize the safety of the transported equipment. To ensure the safety of certain important factory equipment during transportation, this paper designs a wireless three-axis vibration acquisition and storage system [3] using STM32 and FPGA.

Currently, most vibration monitoring devices collect data through wired vibration sensors [4]. However, cables are inconvenient to deploy during transportation, and data cannot be transmitted to the host computer in real-time, making real
