| Abstract: | This artcle briefly discusses the common problems and the corresponding solutions of the RS-485 bus.Besides,it analyzes the disadvantages of the current testing method in the network constituted by the RS-485 bus.In this paper,the RS-485 Hand Detector of web failures has been designed,the schematic diagram bas been schemed out and the selection of the chip and the exploration of the program have been completed.Thereafter,the principles and process of the realization of the web failure detector have been summarized in this paper.Finally,the essay illustrates that this instrument had simplified the detecting process and greatly improved the testing accuracy of the RS-485 web failures. |
