Description
Technical field
The present invention relates to UPS fault detection technique field, be specifically related to a kind of UPS charging panel fault detect machine and UPS charging panel fault detection method, the method is by setting up functional module construction, come by computer program instructions computer for controlling system, these computer program instructions store in a computer-readable storage medium.
Background technology
UPS(uninterrupted power source) be a kind of containing battery energy storage device, take inverter as the power protective equipment of formant.When civil power input is normal, civil power is just transformed to stable alternating voltage for load by rectification, inverter circuit by UPS, simultaneously the charging of complete battery pair; When civil power is abnormal, UPS just by the electric energy stored in battery by DC boosting and inversion is converted to the alternating current powering load of constant voltage, constant frequency.And when there is the abnormal occurrencies such as overload, excess temperature as UPS, load will be changed to bypass end from inversion end-grain cutting by uninterrupted power source, guarantees load end not power down.
The power supply mode of ups system has two kinds, and when civil power input is normal, ups system is powered by charging panel by civil power; Civil power input is abnormal or when inputting without civil power, ups system is then by its powered battery.If charging panel breaks down, civil power is not just powered to ups system by it, and also cannot charge to the battery of UPS, at this moment ups system just can only turn by the powered battery of UPS.Because the need for electricity of ups system is not high, and when commercial power supply is normal, load does not need powered battery, and battery only needs to power to ups system, and now battery will be in the state that small area analysis exports.The long-term small area analysis of battery exports and easily occurs that passivation damages, and the cost of the battery of UPS is very high, and the charging panel because of UPS breaks down and causes cell damage can bring very expensive maintenance cost.

The invention has the beneficial effects as follows: according to the voltage condition of the battery of UPS, if when the normal and battery underfill of civil power, cell voltage does not rise within a period of time, then can judge that charging panel breaks down exactly, to allow related personnel can process charging panel fault in time, thus avoid the battery of UPS to occur the situation of the long-term low discharging current because of charging panel fault, also just reduce battery and occur the risk that passivation damages, workable, be easy to realize, the loss that can effectively avoid cell damage to arrive.Being detected the voltage of its battery by the DSP of UPS self, without the need to increasing hardware again, therefore without the need to transforming UPS, having saved cost.
Accompanying drawing explanation
Fig. 1 is the structured flowchart of UPS charging panel fault detect machine of the present invention.
Reference numeral comprises: UPS 1, UPS charging panel fault detect machine 2.
Embodiment
Below in conjunction with specific embodiment, the present invention is elaborated.
embodiment 1
The UPS charging panel fault detection method of the present embodiment, specifically performed by UPS charging panel fault detect machine 2 as shown in Figure 1, described detection method mainly comprises following three steps.
First, as shown in Figure 1, the DSP(digital signal processor by UPS 1) continue to monitor the real-time voltage of the battery of UPS 1, the described real-time voltage that DSP is detected sends to the controller of UPS 1.UPS 1 has the DSP of the voltage of the battery for monitoring UPS 1 usually, also having alarm, is detected the voltage of its battery by the DSP of UPS 1 self, without the need to increasing hardware again, therefore without the need to transforming UPS 1, having saved cost.
Then, described controller judges that whether following three conditions are satisfied:
Condition one, mains-supplied is normal;
The voltage of the battery of condition two, UPS 1 does not reach the maximum voltage of the battery of UPS 1;
Real-time voltage continuous decrease in 6 hours of the battery of condition three, UPS 1,
When above-mentioned three conditions meet all, described controller just judges the charging panel fault of UPS 1.When civil power is normal and the voltage of the battery of UPS 1 does not reach its maximal value, civil power can be charged the battery by charging panel, so the voltage of battery should be able to slowly rise, therefore, not only if the voltage of the battery of UPS 1 does not rise in sufficiently long Preset Time, on the contrary at continuous decrease, then show that civil power does not charge to the battery of UPS 1 in this section of Preset Time, and the battery of UPS 1 is in continuous discharge, therefore the charging panel of deducibility UPS 1 has broken down, and ups system has turned the powered battery by UPS 1.Arranging of Preset Time need set according to the concrete condition of UPS, can not arrange long, in order to avoid just there is the situation that passivation damages in battery in Preset Time, can not arrange too short, because its voltage when battery charges slowly rises, if Preset Time is too short, the rising of cell voltage not yet obtains embodying the situation that just there will be wrong report charging panel fault in Preset Time.Preset Time is set to 6 hours by the present embodiment, is applicable to most UPS.
Finally, as shown in Figure 1, after judging the charging panel fault of UPS 1, described controller controls alarm and sends sound and light alarm signal, to point out its charging panel fault, reminds the timely handling failure of related personnel.
embodiment 2
The UPS charging panel fault detection method of the present embodiment, specifically performed by UPS charging panel fault detect machine 2 as shown in Figure 1, described detection method mainly comprises following three steps.
First, as shown in Figure 1, detected the voltage of the battery of a UPS 1 every 30 minutes by the DSP of UPS 1, the described real-time voltage that DSP is detected sends to the controller of UPS 1.
Then, described controller judges that whether following three conditions are satisfied:
Condition one, mains-supplied is normal;
The voltage of the battery of condition two, UPS 1 does not reach the maximum voltage of the battery of UPS 1;
The real-time voltage of the battery of condition three, UPS 1 did not rise in 8 hours;
When above-mentioned three conditions meet all, described controller just judges the charging panel fault of UPS 1.
Finally, as shown in Figure 1, after judging the charging panel fault of UPS 1, described controller controls alarm and sends sound and light alarm signal, to point out its charging panel fault, reminds the timely handling failure of related personnel.
The method provided herein, all or part of step wherein by setting up functional module construction, can have been come by computer program instructions computer for controlling system.These computer program instructions store in a computer-readable storage medium.
Finally should be noted that; above embodiment is only in order to illustrate technical scheme of the present invention; but not limiting the scope of the invention; although done to explain to the present invention with reference to preferred embodiment; those of ordinary skill in the art is to be understood that; can modify to technical scheme of the present invention or equivalent replacement, and not depart from essence and the scope of technical solution of the present invention.
