摘　　要：北京谱仪（ＢＥＳⅡ）顶点探测器数据获取系统是北京谱仪数据获取系统的一部分，该子系统电子学采用快总线标准。本文描述了该系统的硬件结构和软件系统，软件包括快总线系统的微码软件和上层控制软件。该系统的死时间为１．５ｎｓ。对ＢＥＳⅡ系统总死时间的贡献小于０．５ｍｓ。Data acquisition system for BES Ⅱ Vertex Chamber (VC) is a part of data acquisition system of BES Ⅱ. The electronic system is based on Fastbus standard.This paper describes the hardware architecture and software of the system. The software system consist of microcode for Fastbus system and upper layer control software.The total dead time of the sybsystem is estimated to be 1.5ms, and the dead time that is contributed by VC DAQ system to whole BES Ⅱ DAQ system is less than 0.5ms.
