摘　　要：多功能一体化原子化器是原子吸收分光光度计采样系统的重要组成部分,要求装置定位在光路上并保证精确可靠.为集成5种功能于一体,硬件设计以STM32为核心的电机控制模块和气路控制模块,采用实时分布式结构.系统利用S曲线算法实现了双轨行进控制定位,并设计了气体压力检测和气路控制,保证系统通气安全.实验结果表明:原子化器能够实现5种功能的快速平稳切换,提高仪器定位精度及效率.Multi-functional integrate atomizer was an important part of the sampling system of atomic absorption spectrophotometer,for device positioning in the optical path to ensure accurate and reliable. In order to integrate the function of five analytical instruments,motor control module and pneumatic control module,which were based on STM32,employed real-time distributed structure for hardware design. The system achieved double-track location by the S-curve algorithm,and gas pressure detection and pneumatic control were designed,ensuring safety of the ventilation. The result shows that the system achieves appara-tus switching fast and steady,improving the positioning precision and efficiency.
