" way to pile up more money ", if accumulator is stolen, can cause emergency power supply product normally to work, and will have a strong impact on the normal raw of people
Live
For the phenomenon that emergency power supply accumulator is the most stolen, the guard method of accumulator is had and locks at mainframe by people
With supervising device etc. is installed, but, these methods can not thoroughly solve problem, needs the biggest manpower and materials support, and
In time the information very first time stolen for accumulator cannot be pass on to relevant departments.Therefore, a kind of emergency power supply electric power storage is developed
The method of the antitheft detection in pond seems most important.
Summary of the invention
Whether the antitheft testing circuit of a kind of emergency power supply accumulator that the present invention provides, solve emergency power supply accumulator
Stolen problem.
The purpose of the present invention can be achieved through the following technical solutions:
A kind of antitheft testing circuit of emergency power supply accumulator, it is characterised in that: include sample circuit, bleeder circuit, limit

Using reaction diode D in described sample circuit, when accumulator battery no-voltage and relay J C disconnect, direct current is female
The voltage of line will not transfer back in accumulator battery.
Beneficial effects of the present invention: by the voltage of M signal end in testing circuit judge emergency power supply accumulator whether by
Steal, not only ensure that emergency power supply can resist the ability of burst power failure, and be able to detect that emergency power supply accumulator
Situation, it is to avoid affect the orthobiosis of people and the operation of enterprise and production.
Accompanying drawing explanation
For the ease of it will be appreciated by those skilled in the art that the present invention is further illustrated below in conjunction with the accompanying drawings.
Fig. 1 is the antitheft testing circuit figure of the present invention a kind of emergency power supply accumulator.
Detailed description of the invention
The antitheft testing circuit of a kind of emergency power supply accumulator, as it is shown in figure 1, include sample circuit, bleeder circuit, current limliting
Circuit, isolation circuit, alarm module, wherein, sample circuit includes accumulator battery, reaction diode D, and bleeder circuit includes resistance
R1, resistance R2, current-limiting circuit includes that resistance R3, isolation circuit include photoelectrical coupler, and alarm module uses buzzer to report
Alert.
One outfan of charger is connected to the sun of the negative electrode of accumulator battery, another outfan and accumulator by relay
Pole connects, and the negative electrode of accumulator battery is connected with dc bus DC-, and the anode of accumulator battery is by connecting the anode of reaction diode
Being connected with dc bus DC+, resistance R1 connects in parallel with accumulator battery with resistance R2 again, resistance R3 one end and resistance R1 and resistance
Node between R2 connects, and the other end is connected with an input of photoelectrical coupler, another input of photoelectrical coupler and storage
The anode of set of cells connects, and an outfan of photoelectrical coupler is connected M signal end and is connected on 3.3V voltage, separately by resistance R4
One output head grounding, M signal end is connected with buzzer.
Under civil power normal power supply state, the voltage of panel detection DC+, DC-, if DC+, DC-are not reaching to specified electricity
Pressure, controls relay J C Guan Bi, thus realizes to battery charging, after DC+, DC-reach rated voltage, controls relay
JC disconnects, thus stops charging a battery.The output of accumulator battery accesses dc bus circuit through reaction diode D, logical
Cross dc bus to power to emergency power supply, use reaction diode D, when accumulator battery no-voltage and relay J C disconnect, directly
The voltage of stream bus will not transfer back in accumulator battery.Accumulator battery output samples the input from reaction diode D1 and electric power storage
The negative electrode sampling of pond group, through divider resistance R1, resistance R2, is reduced to 20V DC voltage by the High Level DC Voltage of accumulator, then
It is connected with photoelectrical coupler through current-limiting resistance R3.
When accumulator battery is without output, the input of photoelectrical coupler does not has voltage, M signal end voltage to be 3.3V, buzzing
Device sends alarm signal；When accumulator battery has output, the input of photoelectrical coupler has voltage, M signal end voltage to be 0V, because of
This can send signal according to buzzer and directly judge the most stolen situation of accumulator battery.
Wherein photoelectrical coupler, on the one hand by good with the weak electricity system of control system for the direct current forceful electric power end of accumulator battery
Isolation, is on the other hand converted to switching signal by the analogue signal of sampling, it is easier to realize the judgement of accumulator battery fault.
