大亚湾中微子实验波形数据获取软件设计

The Designation of the Waveform Data DAQ Software for Daya Bay Neutrino Experiment

介绍了大亚湾中微子实验波形数据读出和数据压缩算法的数据获取软件设计。该软件是以大亚湾中微子实验数据获取系统为基础,在不影响现有电子学系统正常取数的前提下,针对一号实验厅新增的一套前端电子学系统实现波形数据的网络读出、检查、组装、压缩和存盘等功能的软件系统。文中详细说明了波形数据的读出流程以及不同数据压缩方法的实现,并给出了软件的长期稳定性测试结果。

This paper introduces the design and realization of the waveform data readout and compression algo- rithm of the data acquisition software for DayaBay neutrino experiment. The software, based on DAQ of Day- aBay neutrino experiment, implies the functions of reading out data through network, inspection, assembling, compression and storage without affecting the normal working of the existing system, aiming at the added front - end electronics system in the experimental hall 1. In this paper, the waveform data reading process and the im- plementation of different data compression methods are illustrated in detail, and the long - term test results of stability of the software are also presented.
