Abstract

It is a complete equipment which involves with generating plant complete equipment DC power supply panel intelligent monitor and controlling means. Especially it is used in places where DC power supply panel is used like converting station, electric power plant, factory and air port. The complete equipment can be used in converting station whose electric pressure is above 10KV and electric power plant of any capacitance. It is used to settle the settings in DC panel system which does central control, detecting, conservation, alarm and displaying to DC power supply box. This technique includes technical field such as monomer cell voltage detecting of group battery, isolate detecting technique and serial port stretching technique. There are many advantages in this invention. Centralized management can be realized and man-machine conservation can also be realized for its high intelligent and automaticity, complete function and high reliability. Amending working parameter and reacting running state and operating date can be realized through touch screen. It is high quality with low price for the advantages such as high-power random stretching, full automation, auto storing data, self-diagnostic and bug-auto-clear.

Description

technical field [0001] The invention relates to an intelligent monitor and control method of a DC power supply screen, which is used for a complete set of equipment in a substation above 10KV, especially a DC power supply screen used in factories, hospitals, hotels, shopping malls, mines, subways, airports, etc. In places where power plants have to use DC power screens regardless of the installed capacity; the control methods of the DC power screen intelligent monitor include: single cell voltage detection of battery packs, insulation monitoring technology and multi-serial port expansion technology and other technical fields. The DC power screen intelligent monitor and control method are used for centralized control, detection, protection, alarm and display of the DC power cabinet in the DC screen system. Background technique [0002] At present, for the control, detection, protection and alarm of DC power cabinets at home and abroad, single-chip or single-board computers ar...
