基于PC机的多客户响应实时数据采集系统

Design of PC-based data acquisition system meet the need of muliti-client's real time data request

为解决一种基于 PC网络的数据采集系统如何响应多个分散客户对实时数据采集的请求问题 ,建立了一个数据采集端响应的模型 ,提出了一种利用操作系统的多任务 ,程序多线程、时间片分隔法以及缓冲区非空触发法等来实现上述功能要求的方案 ,实现了多个客户端实时数据请求的响应 ,为硬件资源的共享和以数据采集为基础的虚拟仪器的建立提出了一种可响应多用户请求的解决办法。

A module to respond to multi-client's real time data acquisition is set up. The model can solve the problem of how a computer network based data acquisition port responds multi-user request ports. And then, a solution to realize the system by use of OS's multi-task support multi-thread, time scale, nonempty buffer triggering was introduced. Realization of the respond to muti-clietn's real time data acquistion on which the solution for hardware source sharing and establish of data acquistion-based virtual instrument which can response of multi-client based.
