基于DSP的双电源备自投控制器

Design of Intelligent Dual Power Automatic Switching Controller Based on DSP

针对不间断供电的需求,提出了一种基于DSP的双电源备用电源自动切换控制器设计方案,使用AD模块完成数据采集,使用傅立叶算法进行数据处理,通过CAN总线与监控主站进行通信,完成双电源备自投功能;实验验证了该设计的正确性及有效性,为双电源备自投控制器更新换代开辟了一条高性能低成本途径。

Aiming at the demand of uninterrupted power supply,a novel design method of intelligent dual power automatic switching controller based on DSP is presented,The system can sample the signal in the same time with the an analog to digital converter module,and process power quality's data in real time with FFT algorithm,It can also communicate the data to monitoring host with CAN Bus and Ethernet,and finish the order from monitoring host;the experiments verify the feasibility and reliability of the design proposed,the design is an effective way for traditional BZT to upgrade.
