摘　　要：基于VCL组件的体系构架 ,提出一种面向高速数据采集的VCL组件模型。采用“组件类”以属性、方法和事件的形式对数据采集的硬件资源与软件操作进行封装 ,并通过“监视线程类”监视采集状态以激发数据处理事件 ,从而实现高速数据采集与处理的并行。该VCL组件的应用有助于实现数据采集软件的快速。A high-speed data acquisition-oriented VCL component based on the system structure of VCL is put forward. A 'component class' is used to encapsulate the hardware resources and software operations as styles of properties, methods and events.The acquisition state is monitored by a 'surveillance thread' to inspire an event for data processing.Thus, a synchronous high-speed data acquisition and processing is obtained.The application of the VCL component is much helpful to the achievement of a rapid,reliable and visualized design for data acquisition software.
