【摘要】：远程实验台实现了实验室的资源共享,成为目前高校实验室建设中的热点。针对远程实验台应用需求量大而成本较高,结构复杂的特点,提出了一种新型构建方案。该方案主要利用单片机C8051F020代替数据采集卡作为系统的测控核心,通过单机和多机通信相结合的通信方式,可以实现客户端远程实时操作多个实验项目的目标。利用Internet以及LabVIEW实现互联网通信和平台交互。最后结合滤波电路、步进电机驱动电路、电平转换电路等,使用户可以通过网络终端远程采集实验数据,搭建实验电路,观测实验过程。实验表明:新的方案不仅大大的降低了成本,也提升了系统性能和稳定性,满足了目前教学实验改革的需求。
[Abstract]:The remote laboratory platform has realized the sharing of laboratory resources, and has become a hot spot in the construction of university laboratories, aiming at the characteristics of large demand for remote laboratory applications, high cost and complex structure. In this paper, a new construction scheme is put forward, which mainly uses single chip computer C8051F020 instead of data acquisition card as the measuring and controlling core of the system, and communicates with single computer and multi-computer. Can realize the client remote real-time operation of multiple experimental projects, using Internet and LabVIEW to achieve Internet communication and platform interaction. Finally, combined with filter circuit. Stepping motor drive circuit, level conversion circuit, so that users can remote collection of experimental data through the network terminal, build the experimental circuit. The experimental results show that the new scheme not only greatly reduces the cost, but also improves the performance and stability of the system, and meets the needs of the current teaching experiment reform.
