Research And Implementation On Key Technology Of Remote Controllable Virtual Experimental Equipments Based On Internet

The design has deeply researched involved key technology in process of building remote controllable simulated experimental equipments. It provided the user-side simulated experiment platform software of network virtual circuit lab with really-interactable simulated experiment interface software, making experimental instrument in the lab present in user-side simulated experiment platform software with completely-true interface. Meanwhile, according to demand of network virtual circuit lab, the design set up remote controllable experiment instrument system using a virtual instrument product from NI in the sever-side of the virtual circuit lab. It has realized functions of experimental equipments built in user-side experiment platform software.The simulatively-designed objects of entire remotely-controllable simulated experimental equipments are commonly-used YB4320A oscilloscope, MF-47 pointer-type multimeter, DT9205M digital multimeter, EM1716 DC voltage source and SG1692P signal source in the circuit experiment lab. The system design carried on really-simulated fabrication towards both operating interface and functions of measurement, souce generation and power supply of these 5 experiment equipments. According to the need that instrument must be remote controllable, the design also researched software-realized means of long-range data transmission based on Internet.The innovation of the design has constructed the interactable interface and functiong of 5 instruments mentioned above completely truly, and realized their remote control based on Internet. It upbuilt remotely-controllable experimental equipments based on Internet for network virtual circuit lab on significance.
