Direct-current generator unit control system

Abstract

The invention provides a direct-current generator unit control system comprising a controller and a switching power rectifying module. The controller is used to set default parameters in response to the operation by a user, acquire and display information of a unit, the switching power rectifying module and an external power supply in real time, and control the switching power rectifying module and the unit to act correspondingly when judging that a preset condition for opening or closing the switching power rectifying module and the unit is reached according to the default parameters and the information of the external power supply. The switching power rectifying module is used to transmit 48V direct-current power output through DC / DC conversion to a communication base station via a piece of power distribution output equipment. The control system integrates unit control and switching power control of a direct-current generator unit. The controller is used directly to display parameters, and the use of an electric parameter display meter is avoided. The switching power rectifying module and the power distribution output equipment are integrated in hardware equipment of the control system, so that the cost is reduced. The function of intelligent control on a direct-current generator unit is achieved.

Description

technical field [0001] The present application relates to the technical field of generating set control, in particular to a control system of a DC generating set. Background technique [0002] With the development of society, small DC generator sets have become the necessary equipment for communication base stations, and it is the trend of using small spare generator sets for communication base stations. After years of development in the generator set control industry, the control function of the generator set controller has been quite perfect, powerful and intelligent, and the switching power supply has been quite perfect and intelligent in terms of working efficiency, volume and control. [0003] However, for the small (6KW and below) diesel and gasoline DC generators currently on the market, the oil engine controller is composed of an operation panel, a mechanical display head and related buttons. The control method used is simple operation on the panel. Relevant paramet...

Problems solved by technology

[0003] However, for the small (6KW and below) diesel and gasoline DC generator sets currently on the market, the oil engine controller is composed of an operation panel, a mechanical display head and related buttons. The control method used is simple operation on the panel. Relevant parameters are only displayed through the corresponding mechanical meter, and the switching power supply is used alone. After the rectification module, the power distribution output does not have the intelligent management function of the switching power supply for the battery.

[0004] In addition, because the existing DC generator sets will increase the corresponding parameter display headers, resulting in an increase in production costs, and the existing control system is completely controlled manually, which cannot realize the intelligent start function
