Abstract
The invention relates to an abnormal power supply accurate positioning and warning device. The maximum value and the minimum value of output voltage of power supplies are determined according to voltage output of the power supplies, which is detected on the basis of the requirement on the output voltage, resistors R1, R2, R3 and R4 in a resistance voltage divider calculate voltage V1 and voltage V2 of a pin 2 and a pin 4, V1 is equal to the minimum value of the output voltage, V2 is equal to the maximum value of the output voltage, when the voltage output is higher than V1 and lower than V2 through comparison of comparators 1 and 2, the two comparators output high level, potential is still the high level through an AND gate circuit, and a light-emitting diode (LED) lamp is turned off through potential conversion; and low level is output in other states through an AND gate, the LED lamp is turned on through a potential converter, the voltage is abnormal, the LED lamp gives an alarm, and the group of power supplies are abnormal according to the turned-on LED lamp.
Description
Technical field
The present invention relates to server DC power-supply system and other many group power supplies fields, the method for designing of the accurate locating alarm device of specifically a kind of unusual power supply.
Background technology
The fast development of electronic industry, electronic product integrated, complicated degree is increasingly high.The thing followed is the differentiation to power supply requirement, and variation is increasingly high.The system that each is complicated, the power distribution system of the different voltages of many groups that invariably accompany.And electronic product is unusual, more shows the unusual of power supply again.How accurately navigating to unusual power supply, becoming our system intelligent monitoring system is unusual important component part.Thus, this paper has proposed a kind of method that accurately navigates to unusual power supply and report to the police.
Summary of the invention
The method for designing that the purpose of this invention is to provide the accurate locating alarm device of a kind of unusual power supply.
The objective of the invention is to realize by following mode; Comprise power supply changeover device, resitstance voltage divider, comparer 1, comparer 2, AND circuit, electric potential transducer, the linking relationship of each device is following: 1 pin of power supply changeover device connects power input, and 2 pin connect power output end; Resitstance voltage divider is made up of resistance R 1-R4 articulating; Wherein the linking point of resistance R 1, R3 is that 1 pin meets stabilized power source VCC, and the linking point of resistance R 1, R2 is 1 pin that 1 pin connects comparer 2, and the linking point of resistance R 2, R4 is 3 pin ground connection GND; The linking point of resistance R 4, R3 is 1 pin that 4 pin connect comparer 1; 2 pin of comparer 1 and comparer 2 connect 2 pin of power supply changeover device, and 3 pin of comparer 1 and comparer 2 connect 1 pin and 2 pin of AND circuit respectively, and the 3 pin serial connection electric potential transducer of AND circuit connects Led quality inspection lamp; The locating alarming step is following:
According to the power source voltage output that the requirement of output voltage detects, confirm the maximal value and the minimum value of electric power output voltage, through the resistance R in the resitstance voltage divider 1, R2; R3, R4 calculate the voltage V1 and the V2 of 2 pin and 4 pin, make V1 equal the minimum value of output voltage; V2 equals the maximal value of output voltage, through the comparison of comparer 1 and 2, when voltage is exported greater than V1; During less than V2, two comparers are all exported high level, through AND circuit; Current potential or high level through the current potential conversion, do not work the LED lamp then; And other states through with door output all be low level, through electric potential transducer, the LED lamp is lighted, electric voltage exception, LED lamp are reported to the police, and according to the LED lamp of lighting, then can be judged as that group power supply and occur unusual.
The invention has the beneficial effects as follows: use this invention, in the process of the maintenance of power supply and fault analysis, we just can judge that problem has appearred in that group power supply according to the LED that is lighted.So just save the time of a large amount of unusual power supplys of investigation, directly just can carry out the fault eliminating unusual power supply takes place.And employed components and parts all are modal electronic original parts in the whole circuit, and price is very cheap, can't bring the rising of a cost to total system, have very strong operability.
