Control system for carrying out diagnostic analysis on power supply work

Abstract

The invention discloses a control system for carrying out diagnostic analysis on power supply work, which comprises an acquisition circuit, a fault detection circuit, a linear voltage regulator LDO, an analog to digital converter ADC, a programmable controller FPGA, a signal converter, a monitor, a control switch, a battery and a charging device, wherein one end of the acquisition circuit serves as power supply output, and the other end is respectively connected with the linear voltage regulator LDO and the analog to digital converter ADC; and the port of the programmable controller FPGA is respectively connected with the linear voltage regulator LDO, the analog to digital converter ADC, the fault detection circuit, the signal converter, the charging device, the control switch and the battery. The preset voltage threshold can be extremely conveniently modified inside the programmable controller FPGA, and the same power supply monitoring system can monitor power supply conditions of different sub circuits by the main power supply; and when power supply of the main power supply fails, emergency power supply is quickly carried out, the sub circuits can be ensured to work normally, and the power supply quality is improved.

Description

technical field [0001] The invention relates to the field of power supply control, in particular to a control system for diagnosis and analysis of power supply work. Background technique [0002] At present, in many devices, the main power supply is required to supply power to the sub-circuits, and at the same time, the power supply needs to be monitored. In the commonly used monitoring system for the power supply of the main power supply to the sub-circuits, only one voltage threshold is set. When monitoring different sub-circuits , the voltage threshold needs to be changed, and it can be used after repeated debugging, which is very troublesome to use. [0003] In addition, during the working process of some precision devices, it is not only necessary to monitor different sub-circuits conveniently, but also to ensure that the sub-circuits can still supply power normally when the main power supply fails. Contents of the invention [0004] The object of the present inv...
