| Abstract: | This dissertation designs interface hardware electrocircuit which connects PC machine and singlechip with RS-485 chief-line, and also designs software agreement and correspondence software. This technology can apply to minisize-compute monitoring of power supply system. In monitoring system PC machine connects singlechip which connects relative sensor and relay through RS-485 chief line network, thus it can realize long-distance monitoring of power supply. |
