摘要 设计了PC机和单片机连接RS485总线的接口硬件电路,以及软件协议和通信软件。该技术可应用于供电系统微机监控,监控系统中主控机(PC机)通过RS485总线网络联结从机(单片机),从机联结相应的传感器和继电器,从而实现供电系统的远程检测监控。 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.
