| Abstract: | Power electric equipment often requires remote communication in very bad electricity environment. The paper analyses the RS- 485 bus reliability applying to actual system in theory. And basing on the different conditions, it researches practicable ways to improve the reliability of RS- 485 bus system, respectively from different aspects such as network configuration, transient voltage, the reflection interference and common mode interference. |
