Description

UPS accumulator does not connect or abnormal detector
Technical field
The utility model relates to UPS accumulator and detects, and particularly a kind of UPS accumulator does not connect or abnormal pick-up unit.
Background technology
Because UPS has charge function conventionally, DC port has DC voltage to exist always under normal circumstances, and whether this just makes UPS connect accumulator or be extremely difficult to make effective judgement.And for UPS power supply be uninterruptedly its most key attribute, if because accumulator does not connect or is abnormal and cause load power-off to be a very serious problem.
Existing UPS accumulator does not connect detection technique patent and mainly contains two kinds:
Publication number is that CN 102901903 A publication numbers are " UPS accumulator disconnection detection device ", the in the situation that at charger, oneself opening, if charging current enough greatly, is judged accumulator and is not opened circuit, if the very little charge closing of charging current device judges by battery tension whether accumulator does not connect.Existing problems: 1. this pick-up unit need to have charging current detecting circuit; 2. necessary charge closing device in the time testing, this just makes UPS can not adopt separately charging voltage and battery tension to input as power supply, otherwise can cause power interruption.
Publication number is that CN 103176100 A publication numbers are by controlling ChargeOn/Off switch for " detecting method and device that battery does not connect in a kind of UPS ", control charging panel relay and whether battery is charged, then by judging that cell voltage detects battery and whether connects normally.Existing problems: the problem that rear UPS can not adopt separately charging voltage and cell voltage to input as power supply is closed in same existence charging, otherwise have equally the risk of power interruption.Here mention and carry out time bias with charging panel electrochemical capacitor, but charging panel capacitance is had relatively high expectations.
Summary of the invention
The purpose of this utility model is to provide a kind of UPS accumulator not connect or abnormal pick-up unit, and without charging current being detected, charge without turn-offing, not affecting the pick-up unit that UPS moves, this device circuit is simple in structure, applied widely.
For achieving the above object, the technical solution of the utility model is: a kind of UPS accumulator does not connect or abnormal detector, comprises that one is connected to voltage sampling circuit and a single-chip microcomputer of UPS accumulator; The output terminal of described voltage sampling circuit is connected with the DC/DC charger of the input end of single-chip microcomputer, ups power and one end of a switching tube; The first output terminal of described single-chip microcomputer is connected to the control end of switching tube, and the second output terminal of described single-chip microcomputer is connected to abnormality alarming circuit; The other end ground connection of described switching tube.
In the utility model one embodiment, described abnormality alarming circuit is pilot lamp or display panel.
In the utility model one embodiment, described switching tube is metal-oxide-semiconductor; One end of described switching tube is the drain electrode of metal-oxide-semiconductor, the grid that the control end of described switching tube is metal-oxide-semiconductor, the source electrode that the other end of described switching tube is metal-oxide-semiconductor.
In the utility model one embodiment, described switching tube is triode; One end of described switching tube is the collector of triode, the base stage that the control end of described switching tube is triode, the emitter that the other end of described switching tube is triode.
In the utility model one embodiment, described single-chip microcomputer is MC9S08FL16.
Compared to prior art, the utlity model has following beneficial effect:
1, pick-up unit of the present utility model, without charging current is detected, possesses circuit structure advantage simple, applied widely;
2, this pick-up unit coordinates existing Software in Single Chip Microcomputer Control, can realize without charging current is detected, utilize PWM to control and turn down charging voltage, instead of turn-off and charge, when detection, charger is not closed, the problem that can not cause charging voltage to interrupt, avoid causing while adopting charging voltage or battery tension to input as UPS working power the interruption of power supply, can not cause power interruption even if accumulator does not connect, efficiently solve UPS execution accumulator in prior art and do not connect the problem that while test, charger turn-offs yet.
Brief description of the drawings
Fig. 1 is the circuit block diagram of the utility model pick-up unit.
Embodiment
Below in conjunction with accompanying drawing, the technical solution of the utility model is specifically described.
A kind of UPS accumulator of the present utility model does not connect or abnormal detector, comprises that one is connected to voltage sampling circuit and a single-chip microcomputer of UPS accumulator; The output terminal of described voltage sampling circuit is connected with the DC/DC charger of the input end of single-chip microcomputer, ups power and one end of switching tube; The first output terminal of described single-chip microcomputer is connected to the control end of switching tube, and the second output terminal of described single-chip microcomputer is connected to abnormality alarming circuit; The other end ground connection of described switching tube.
Described abnormality alarming circuit is pilot lamp or display panel; Described switching tube is metal-oxide-semiconductor; , the drain electrode that one end of described switching tube is metal-oxide-semiconductor, the grid that the control end of described switching tube is metal-oxide-semiconductor, the source electrode that the other end of described switching tube is metal-oxide-semiconductor.
Described single-chip microcomputer is MC9S08FL16.
Described switching tube also can be triode; One end of described switching tube is the collector of triode, the base stage that the control end of described switching tube is triode, the emitter that the other end of described switching tube is triode.
For allowing those skilled in the art more understand hardware configuration scheme of the present utility model; tell about the utility model below in conjunction with specific embodiment; it should be noted that the software section that this process relates to is not protection content of the present utility model, the explanation of just carrying out in order to allow technician more understand the utility model.
As shown in Figure 1, under normal condition, UPS accumulator is not connect or abnormal detection, it is low level signal that single-chip microcomputer sends Charge Off signal, switching tube Q1 is off-state, the DC/DC charger on ups power and on the charging process of UPS accumulator without impact.
When UPS accumulator not being connect or when abnormality detection, first sending Charge Off signal by single-chip microcomputer is pwm signal, this signal is adjusted the voltage feedback signal of DC/DC charger by switching tube Q1, the charging voltage of DC/DC charger output is turned down a little more than storage battery low-voltage protection point, single-chip microcomputer will judge battery tension simultaneously, if battery tension is not along with quick drop is for accumulator connects or extremely, single-chip microcomputer sends alarm signal to abnormality alarming circuit, abnormality alarming circuit can not connect or extremely by pilot lamp or Display panel information notification user accumulator, if battery tension still maintains high voltage for accumulator is normal.
It should be noted that, before accumulator testing, first judge whether normal a period of time (this time is to be charged to the saturated required time by charger after battery discharging) of civil power, when getting rid of test accumulator because of electric discharge after situation in low pressure.
Be more than preferred embodiment of the present utility model, all changes of doing according to technical solutions of the utility model, when the function producing does not exceed the scope of technical solutions of the utility model, all belong to protection domain of the present utility model.
