本文介绍了一种数据采集系统，该系统由基于fpga的电子器件和面向对象的读出软件组成，该软件是根据多通道探测器的需要而开发的。DAQ电子学的设计目标是开发一种经济实惠且可扩展的多通道系统，该系统足够灵活，可以轻松适应实验要求。模拟电路集成在单独的模拟板上，便于适应不同的实验。电子器件的核心是一个由多达81个fpga组成的分层系统，分为三层。它以10至40MHz的采样率使用12位adc数字化多达480个通道。电子设备通过pci桥接到商用处理器PMC板。
In this article a data acquisition (DAQ) system is presented consisting of FPGA-based electronics and an object-oriented readout software that has been developed for the needs of multi-channel detectors. The design goal of the DAQ electronics was to develop an affordable and scalable multi-channel system that is flexible enough to be easily adapted to the experiment requirements. The analog circuitry is integrated on separate analog boards for easy adaptation to different experiments. The heart of the electronics is a hierarchical system of up to 81 FPGAs organized in three layers. It digitizes up to 480 channels with 12 bit ADCs at 10 to 40MHz sampling rate. The electronics are interfaced by a PCI-bridge to a commercial Processor PMC board.
