Abstract
The invention relates to a UPS (uninterrupted power supply) storage battery circuit breaking detection method. The UPS storage battery circuit breaking detection method is finished by establishing a function module framework and controlling a computer system by a computer program instruction. The UPS storage battery circuit breaking detection method comprises the concrete steps as follows: when a charger is started, if a charging current is large enough, judging that a circuit of a storage battery is not broken. According to the UPS storage battery circuit breaking detection method, the UPS storage battery can be subjected to circuit breaking detection in an on line manner, and smoothness of a charging process is guaranteed.
Description
Technical field
The present invention relates to UPS accumulator broken circuit detecting method, the method is finished by computer program instructions control computer system by setting up functional module construction.
Background technology
Accumulator is the requisite ingredient of UPS (uninterrupted power source).UPS inputs when normal load supplying, and its charger is to charge in batteries simultaneously; After the input of UPS disconnects, then need to be responsible for power supply by accumulator.If open circuit in UPS accumulator accident when input is normal; UPS does not in time detect this situation; then UPS just can't power after input disconnects, and this allows UPS lose original defencive function, and this fault is a destructive strike to load that can not interruption of power supply.
Because when accumulator opens circuit, there is not output voltage, so traditional UPS accumulator broken circuit detecting method is to judge according to the size of cell voltage whether accumulator opens circuit, particularly, default threshold voltage, if record the accumulator current voltage greater than threshold voltage then judge accumulator and do not open circuit, if record the accumulator current voltage less than threshold voltage then judge accumulator and open circuit.But the 1st page of latter end of patent documentation CN1157926A instructions pointed out, charger directly links to each other with battery the two poles of the earth, it is the voltage of charger or the voltage of accumulator that detection means can't be told measured, suppose that accumulator opens circuit, but charger still can output voltage, and detection means records current voltage greater than threshold value, thinks that accumulator does not open circuit, but measured is the voltage of charger in fact, and accumulator in fact opens circuit.The 1st page of latter end of patent documentation CN1157926A instructions provided the method that detects again cell voltage behind the charge closing device simultaneously.In addition, some traditional UPS accumulator broken circuit detecting method need to be closed input and the charger of UPS, turns by accumulator and is responsible for power supply, detects cell voltage again, judges whether accumulator opens circuit.Above-mentioned existing solution can affect the normal operation of UPS and the fluency of charging process.
Summary of the invention
The technical matters that the present invention faces is, how online to the detection of opening circuit of UPS accumulator, and guarantees the fluency of charging process.
The invention thinking: in the situation that charger has been opened, suppose that accumulator does not open circuit, as long as the accumulator electric energy is not in the saturation region, charger will be with enough large electric current to charge in batteries.
Under this thinking, provide UPS accumulator broken circuit detecting method, it is characterized in that, in the situation that charger has been opened, if charging current is enough greatly then judge accumulator and do not open circuit.
Beneficial effect: in the situation that charger has been opened, if accumulator does not open circuit, as long as the accumulator electric energy is not in the saturation region, just can according to charging current enough greatly this testing result judge that directly accumulator does not open circuit, detect and need not the charge closing device.For said circumstances, the present invention need not the charge closing device, and the detection of opening circuit that can carry out the UPS accumulator online can not affect the work of UPS main circuit, and make charging process more smooth, and deterministic process is simpler.Be used for to weigh charging current whether enough large threshold current preset as the case may be.
In the situation that charger has been opened, even accumulator does not open circuit, if but the accumulator electric energy is in the saturation region, charging current is large not, whether can't judge immediately accumulator and open circuit this moment, need to adopt following operation steps: the charge closing device, then judge according to the size of cell voltage whether accumulator opens circuit.Do not open circuit if enough judge greatly accumulator according to cell voltage, then reopen charger, reopening charger should not overcharge as necessary condition take accumulator, prevents accumulator super-charge.After the charge closing device, judge according to the size of cell voltage accumulator is preferably delayed time before whether opening circuit, this is in order to allow fully discharging in order to avoid affect the voltage detecting result such as energy storage devices such as electric capacity in the circuit.Judging before whether accumulator open circuit, carry out at set intervals the charge closing device one time, then detect the size of cell voltage, reopen again the step of charger, judge according to the size of the cell voltage that repeatedly records whether accumulator opens circuit.
In the situation that charger is not opened, obviously can directly judge according to the size of cell voltage whether accumulator opens circuit.
In the said circumstances, warn after opening circuit judging accumulator.After warning, continue to judge according to the size of cell voltage whether accumulator opens circuit, and does not open circuit if judge accumulator, then remove warning.
Embodiment
Below describe UPS accumulator broken circuit detecting method in detail.
Judge at first whether charger is opened.
(1) in the situation that charger is not opened, directly judges according to the size of cell voltage whether accumulator opens circuit.
(2) in the situation that charger has been opened:
(2.1) if charging current enough greatly then judge accumulator and do not open circuit;
(2.2) if charging current is large not, then closing at set intervals a charger then delays time, judge according to the size of the cell voltage that repeatedly records whether accumulator opens circuit again, if judging accumulator does not open circuit, just be necessary to reopen charger, whether overcharge but before reopening charger, should detect first accumulator, only have accumulator not overcharge, just reopen charger.
In the said circumstances, warn after opening circuit judging accumulator.After warning, continue to judge according to the size of cell voltage whether accumulator opens circuit, and does not open circuit if judge accumulator, think that then open circuit fault repairs, so remove warning.
The method that this paper provides, all or part of step wherein can by setting up functional module construction, be finished by computer program instructions control computer system.These computer program instructions are stored in the computer-readable recording medium.
