LHD数据采集系统每次拍摄可处理>600 MB数据。该系统采用了全分布式数据处理和面向对象的系统设计思想。通过在数据处理中引入面向对象的方法，实现了其广泛的灵活性，其中对象共享和类库为网络客户-服务器编程提供了统一的数据处理方式。对象类库用C++语言描述，通过商业软件HARNESS提供网络对象共享。对于CAMAC设置，Java脚本可以使用C++类库，从而建立面向对象数据库和WWW服务器之间的关系。在铲运机试验中，CAMAC系统和Windows NT操作系统分别用于数据的数字化和采集。为了实现LHD数据采集的目的，在Windows NT上开发了新的CAMAC处理软件，用于操作SCSI连接的机箱控制器。CAMAC命令列表和诊断数据类在客户端和服务器计算机之间共享。采用面向对象的程序设计方法，可以将诊断数据块作为对象的一部分来处理。
The LHD data acquisition system handles >600 MB data per shot. The fully distributed data processing and the object-oriented system design are the main principles of this system. Its wide flexibility has been realized by introducing the object-oriented method into the data processing, in which the object sharing and class libraries will provide the unified way of data handling for the network client-server programming. The object class libraries are described in C++, and the network object sharing is provided through the commercial software named HARNESS. As for the CAMAC setup, the Java script can use the C++ class libraries and thus establishes the relationship between the object-oriented database and the WWW server. In LHD experiments, the CAMAC system and the Windows NT operating system are applied for digitizing and acquiring data, respectively. For the purpose of the LHD data acquisition, the new CAMAC handling software on Windows NT have been developed to manipulate the SCSI-connected crate controllers. The CAMAC command lists and diagnostic data classes are shared between client and server computers. A lump of the diagnostic data can be treated as part of an object by the object-oriented programming.
