Development of Voice Interaction Vibration Monitoring System Based on STM32

摘要: 传统振动监测系统在中小型工业场景中部署多节点时，常存在结构冗余、协同响应慢等问题，影响监测的有效性与运维效率。为此，本研究设计了一种基于一主多从架构、支持语音交互的振动监测系统，选用STM32F405RGT6作为核心控制单元，构建“主机集中管控–从机分布式采集”体系，整合PKG-100压电振动传感器、E22-400T22D LoRa通信模块及ASRPRO离线语音交互模块，实现振动信号实时采集、边缘端异常预处理及多节点数据可靠交互。该系统结构紧凑，待机电流低于50 mA，适用于电池供电场合，并可扩展至10个从机节点，能够较好满足中小型工业设备多位置振动监测的需求，在兼容性与可扩展性方面具有较好的实用性。

Abstract: When traditional vibration monitoring systems are deployed with multiple nodes in small and medium-sized industrial scenarios, there are often problems such as structural redundancy and slow collaborative response, which affect the effectiveness of monitoring and operational efficiency. To this end, this study designed a vibration monitoring system based on a one master multi slave architecture that supports voice interaction. STM32F405RGT6 was selected as the core control unit, and a “centralized control of the host and distributed acquisition of the slave” system was constructed. The PKG-100 piezoelectric vibration sensor, E22-400T22D LoRa communication module, and ASRPRO offline voice interaction module were integrated to achieve real-time vibration signal acquisition, edge end anomaly preprocessing, and reliable interaction of multi node data. The system has a compact structure with a standby current of less than 50 mA, suitable for battery powered applications, and can be expanded to 10 slave nodes, which can better meet the needs of multi position vibration monitoring for small and medium-sized industrial equipment. It has good practicality in terms of compatibility and scalability.
