求翻译：对整个直流系统的运行状态进行实时监控，由RS485通信接口与变电所综合自动化系统上位监控机通信、实现遥控、遥测、遥信功能，协议开放，满足无人值班的要求。是什么意思？

Real-time monitoring of the operational status of the entire DC system, position monitoring machine communication rs485 communication interface with integrated substation automation system, realize remote telemetry, remote signaling function, the opening up of the agreement, to meet the requirements

On the whole DC system for the operating status, real-time monitoring by RS 485 communication interface with an integrated automation system based on monitoring the communications, for remote control, telemetry, remote letter agreement, open, for there is no duty.

Carries on the real-time monitoring to entire direct current system running status, by the RS485 correspondence connection and on the transformer substation synthesis automated system the position monitoring machine correspondence, the realization remote control, the telemetering, the remote letter

Real-time monitoring of the entire DC system running from RS485 communication interfaces and substation integrated automation system communication between upper monitoring, remote control, telemetry, remote signaling function, Protocol open, meet the demands of unattended.
