摘要:

针对传统机械式接触器在智能化控制系统中的局限性,设计并实现了一种基于STM32微处理器的智能化无触点接触器。采用STM32作为核心控制器,利用其I/O端口资源和强大的嵌入式处理能力,构建人机交互界面,并实现对接触器控制信号的实时采集与处理。同时,通过无源滤波电路有效抑制电磁干扰,确保系统在复杂电磁环境下稳定运行。对核心组件进行电磁兼容(EMC)试验和冲击耐压试验等,测试结果显示在不同工况下均表现出良好的控制精度和稳定性,完全符合设计要求。

Abstract:

To address the limitations of traditional mechanical contactors in intelligent control systems, an intelligent contactless contactor based on the STM32 microprocessor has been designed and implemented.The STM32 is utilized as the core controller. Its I/O port resources and powerful embedded processing capabilities are utilized to construct a human-machine interaction interface and realize real-time acquisition and processing of contactor control signals.Meanwhile, a passive filter circuit is designed to effectively suppress electromagnetic interference, ensuring the system’s stable operation in complex electromagnetic environments.Electromagnetic compatibility (EMC) tests and impulse voltage withstand tests are conducted on core components.The test results show that it exhibits excellent control accuracy and stability under various operating conditions, which can meet the design requirements.

Key words: STM32 microprocessor, non-contact contactor, EMC, intelligent, passive filter
