| Abstract: | The data gather system made by micro controller may make up of a multi computer system expediently with the RS 485 bus, which can gather data synchronously in parallel. However, along with the application of multi computer, the reliability of data communication is vital in the whole application system. Here comparative fully proposed some hardware and software measures of enhancing the reliability of multi computer system. The measures applied in practice system shows that the effect of using the measures is very good. |
