摘　　要：针对触点间燃弧时间及电弧释放的能量是诱发继电器触点粘连的主要原因,设计了基于DSP的触点电弧数据采集卡,给出了采集卡软硬件设计方法,并研究了继电器控制小功率直流电动机时,燃弧时间和电弧释放能量的的测量技术。该采集卡具有与PC机的通信功能,改进了继由器电寿命检测技术。Aiming at that the arcing time and the arc energy are the main reasons for the contact adhering of the relay, an arc data acquisition card based on DSP was designed, and its software and hardware design were proposed. The arcing time and arc energy measurement technology was studied on the condition that the relay controlled low power DC motor. This data acquisition card can communicate with PC and improve the electrical endurance detecting technology of relay.
