Embodiment Construction

[0035]The following will be described in detail in conjunction with examples.

[0036] 1. Build the virtual instrument server, test server, data acquisition card and experiment box as follows figure 1 The local area network (LAN) is shown; the LAN is connected to the Internet through a proxy server, and the client can conduct remote virtual experiments through a browser. The virtual instrument server adopts Sugon 4000A mainframe and Tsinghua Tongfang desktop with dual-core processor as the test server, and the client can be an ordinary PC.

[0037] The 68pin data acquisition card PCI6221 used in this system is the M series multi-function data acquisition card produced by National Instruments; PCI6221 connects the test server and the experiment box through the PCI bus interface. The main board of the experimental box and the 8 sensor modules used in conjunction with the main board of the experimental box are self-developed.

[0038] There are 6 general-purpose slots on the mo...

Abstract

The invention relates to a sensing detection experimental method based on networked virtual instruments, and belongs to the technical field of sensing detection experimental application. The sensing detection experimental method is based on a sensing detection system of the networked virtual instruments. The system relates to system hardware lap joint and software architecture. By means of the method, remote control and real-time detection of sensing experimental boxes and experimental instruments can be achieved, a virtual laboratory environment can be provided for experimenters remotely, and the utilization rate of experimental equipment and the utilization rate of a laboratory can be increased. Meanwhile, by means of the method, key technologies of application of the networked virtual instruments can be achieved, a professional, efficient and novel sensing detection educating and learning experimental platform is provided for a great number of college teachers and students, the problem that it is difficult for students to carry out practice is solved, high-quality resources can be shared, and beneficial exploration is carried out on discussion and solution of the problem that college experimental resources are imbalanced.

Description

technical field [0001] The invention relates to a sensory detection experiment method based on a networked virtual instrument, belonging to the technical field of sensory detection experiment application. Background technique [0002] Networked virtual instrument organically combines network technology, virtual instrument technology and test technology, which not only has flexibility, reliability and openness, but also fully embodies the sharing function of network resources. Networked virtual instruments play an increasingly important role in various fields such as education, scientific research and production. [0003] At present, the networked virtual experiment system has been studied at home and abroad, and some achievements have been made. For example, the Electrical Engineering Department of Portland University in the United States has established a network laboratory with relatively complete functions based on virtual instruments, which has been applied in several c...
