In order to realize remote control of electrical towage system, the structure of Asp.Net was introduced and its advantages in programming, configuration, disposition, debugging and safety were analyzed. Some basic concept of networked control system (NCS), which is a new study field that integrates computer, communication technology and control technology, was introduced. The structure of the whole Web system was described and then, how to establish IIS6 Web server and how to create a Web site on it were introduced. Networked control system based on Asp.Net was established and some problems in its construction, including there is no way to directly transfer variables through Web form, were discussed. Some programs were provided to explain how to transfer control variables through Asp.Net. Some programs about how to create Web form, which is different from and more efficient than the traditional ASP, were also provided. The real-time problem of networked control system was discussed and some measures were proposed to improve real-time property. Last, some graphs and results about our experiment were presented, which shows that an electromotor in long distance was successfully controlled through constructing IIS6 Web server and LAN. Results prove the reliability and the validity of Asp.Net in remote control.
