| Abstract: | The shortcomings of the present computer survey and control system in hydraulic model tests are firstly analyzed in this article. The principles as well as the characteristics of computer long_range I/O control are then introduced. Finally the ideas of using computer long_rang I/O control technology,changing the simulated communication of present survey and control system into digital communication, and constructing the RS 485 based industrial control net to a large_scale scattered long_range survey and control system of the hydraulic model test are putted forward. |
