Abstract

The invention relates to an intelligent AC distribution monitoring system, in particular to an intelligent AC distribution monitoring system applied to the electric power distribution of an unattended operation type astronomical telescope, and consisting of five main parts including a system control unit, a distribution output unit, an electric quantity monitoring unit, a human machine interface module, an AC/DC power source and the like, wherein the system control unit is connected with the distribution output unit, the electric quantity monitoring unit and the human machine interface module, and the system control unit transmits the voltage information and the current information acquired by the electric quantity monitoring unit to the human-machine interface module for the local display treatment; simultaneously, the acquired electric quantity information and system existing state are transmitted to a remote control computer through an Ethernet network, thus the operation control of the distribution output unit is realized. The system can realize safe and flexible remote operation control and monitoring of the electricity distribution system of the unattended operation type astronomical telescope.

Description

technical field [0001] The invention relates to an intelligent AC power distribution monitoring system, in particular to an intelligent monitoring system suitable for the power distribution of unattended astronomical telescopes. Background technique [0002] Affected by human activities and the natural environment, astronomical telescopes are often built in relatively remote places. The living and working conditions in these places are relatively poor, which brings inconvenience to the staff. It will be of great practical significance if the garrison of personnel can be reduced, or even unattended, and the operation of the telescope can be realized by remote control. At present, the remote control of the telescope is mainly focused on the remote transmission of observation data, and the power supply operation and abnormal handling of the entire instrument and ancillary equipment need to be realized by on-site staff, which cannot achieve true unattended operation.
