摘要
利用LXI总线设计了一个由计算机控制的智能系统,实现了对设备的远程测量和控制。在硬件设计上提出了基于LXI总线的组件方案,这种结构为组建测试系统提供了最佳的灵活性,突破了测试地点和连接设备数量的局限性。在软件设计中,在基于Visual C++6.0的开发环境下,通过调用VISA的标准API函数和LABVIEW生成的动态链接库,提出了对LXI设备进行控制的方法。实验表明,该系统实现了通过以太网口对设备进行远程控制的目的,并为今后对以太网的LXI设备测试的扩展打下了基础。
An intelligent system controlled by computer is proposed based on the LXI bus, which realizes the remote measurement and control for equipments. In the hardware, the component of the program is proposed based on LXI bus, and the structure provides the best flexibility for the system and broke through the confine of test sites and the number of equipment. In the software, by using the API of VISA and the DLL of LABVIEW, a method of control equipments is presented based on the Visual C＋ ＋-6.0. The experiment results show that the system realizes the purpose of remote control equipments by using Ethernet,and lay the foundation of expanding the remote test of Ethernet LXI devices in the future.
