Research and development of database for data acquisition middleware

本课题的研究计划是研究一种新的数据采集模型，旨在建立一种新的数据采集系统配置方法，而这种配置方法是以往数据采集系统所没有的，并且与操作系统、语言、通信协议无关。重点研究和开发了组成数据采集系统所必需的组态数据库和分布式数据库。根据数据采集过程的每个角色，需要大量的参数。例如，在使用被称为CC/NET的CAMAC控制器的情况下，当必要的CAMAC指令在数据库中时，有进行实验而不修改程序代码的优点。XML用于描述此配置参数。XML是WEB技术中描述信息的主要技术。另外，如何管理和使用为每个DAQ过程动态生成的公共数据库，也是一个需要解决的问题。使用Apache服务器框架的WEB服务，是用的。例如，WEB浏览器可以作为DAQ上的WEB服务获取挂载状态信息。从而明确了能够统一管理DAQ的各种分布式数据。

The research plan is to research a new data acquisition model, and to aim at the establishment of a new system configuration method while it is not in a past data acquisition system, and independent of OS, the language, and the communication protocol.In this research, the data base for the data acquisition was researched and developed. Especially, a configuration data base and a distributed database which is necessary to compose the data acquisition system, were researched and developed. A lot of parameters are needed according to each role of the data acquisition process. For instance, there is an advantage of proceeding experiment without modifying the program codes when a necessary CAMAC instructions are in a data base, in case of using a CAMAC controller's called CC/NET. XML is used to describe this configuration parameter. XML is a major technology to describe information on WEB technology. Generalizing was achieved by describing all parameters by the XML specification.Moreover, another issue was how to manage and to use common database dynamically generated to each DAQ process. Apache server using the framework of WEB service, is used. For instance, WEB browser could retrieve status information in mounting as the WEB service on DAQ. As a result, it has made clear to be able to manage a variety of distributed data of DAQ uniformly.
