在自动控制、通信等应用领域中,某些情况下需对操作现场进行瞬态信号测试,有时也涉及对多路信号进行故障诊断和分析。这些场合都需要系统提供多通道同步高速数据采集与处理单元,研制了一种低成本、多通道同步采集的数据采集和处理系统。该系统是以同步采样芯片MAX125为A/D采样芯片、定点DSP芯片TMS320LF2407为主处理器,它具有体积小、功耗低、使用方便、处理数据量大、处理精度高、性价比高等优点。
In some applications such as automatic control and communications, transient signal tests on the operation site are required in some cases, and fault diagnosis and analysis of multiple signals are sometimes involved. These occasions require the system to provide multi-channel synchronous high-speed data acquisition and processing unit, developed a low-cost, multi-channel synchronous acquisition data acquisition and processing system. The system takes the synchronous sampling chip MAX125 as the A / D sampling chip and the fixed-point DSP chip TMS320LF2407 as the main processor. The system has the advantages of small size, low power consumption, convenient use, large data processing amount, high processing precision and high cost performance.
