Description
Technical field
Whether normally the utility model relates to a kind of battery failures testing circuit, specifically, relate to a kind of on-line testing uninterruptible power system battery testing circuit that is used for.
Background technology
For uninterruptible power system, whether backup battery is online.Determined whether uninterruptible power system has the function of " uninterruptedly ".Battery is not online to be to cause uninterrupted power source can to have the multiple fault of gap power supply at crucial moment.If whether online a kind of reliable battery detection module arranged, when battery occurring when not online, provide alerting signal immediately, will powerful guarantee be provided to the reliable and stable work of uninterruptible power system.Because uninterruptible power system will charge to battery under main electric electric power thus supplied, after the main electricity power supply failure, be system's power supply by battery.Charging port is the input port of battery.Just because of the existence of charge function, so even battery is not online, the voltage that the cell input terminal mouth also has suitable value exists.Directly detect the whether online purpose of battery through battery port voltage being detected to reach.If detect through electric current, being not quite similar again of the characteristic of the battery of different brands, even same Battery pack also can be along with the increase of service time, its internal characteristic also can be issued variation.So the threshold values of current detecting just is difficult to accurately set, and has received influence with regard to the stability that makes electric current testing like this.
The utility model content
The online detection module of a kind of uninterrupted power source battery that the utility model designs in order to solve the problems of the technologies described above just.
The utility model solves the technical scheme that its technical matters adopted:
The online detection module of a kind of uninterruptible power system battery comprises and follows inspection pulse generating circuit, voltage detecting circuit, auxiliary power circuit and electronic power switch.The output that follows the inspection pulse generating circuit links to each other with the drive end of electronic power switch, and the electronic power switch output terminal links to each other with the voltage detecting circuit input end, and auxiliary power circuit provides direct supply for following inspection pulse generating circuit and electronic power switch; Following the inspection pulse generating circuit, to produce the pulse decide frequency be that electronic power switch provides respective drive voltage; Wherein voltage detecting circuit is made up of voltage comparator, delay circuit, monostable circuit and signal output apparatus; Anode links to each other with the voltage detecting circuit input end; The voltage detecting circuit output terminal links to each other with the delay circuit input end, and the delay circuit output terminal links to each other with the monostable circuit input end, and the monostable circuit output terminal links to each other with signal output apparatus; Signal output apparatus links to each other with warning device, and resetting means links to each other with the reset terminal of monostable circuit.
The online detection module of said a kind of uninterruptible power system battery, it follows the inspection pulse generating circuit is made up of time-base integrated circuit LM555 and peripheral components, and the generation cycle is 70 seconds, and dutycycle is 0.9 fixed cycle pulse signal.
The online detection module of said a kind of uninterruptible power system battery, its electronic power switch uses the switch mosfet pipe.
The online detection module of said a kind of uninterruptible power system battery, its signal output apparatus is exported with passive node and open-collector triode mode.
1, principle of work
The core devices that follows the inspection pulse generating circuit is time-base integrated circuit LM555, and LM555 is 70 seconds through the generation cycle that cooperates with peripheral components, and dutycycle is 0.9 fixed cycle pulse signal.Remove power controlling switch MOS pipe through this pulse signal.Formation is closed short time of the fixed cycle of charge circuit.After charge circuit was closed, charging port (cell input terminal mouth) was the voltage that the outside feeds.If battery is not online, then the voltage of port is 0V, and voltage detecting circuit detects that cell input terminal mouth voltage is low then can to send alerting signal.If battery is online and in the nominal voltage scope, then voltage detecting circuit is failure to actuate.Though if battery has fault at input port certain voltage to be arranged, not in the nominal voltage scope, then also can to detect cell voltage low and go out alerting signal for voltage detecting circuit, thinks that also this kind situation is the not presence of battery.
Have no progeny when the pass of the charge circuit of short time, it is open-minded that charge circuit recovers again, if battery is not online, voltage detecting circuit detects port again has normal voltage; Then can remove failure alarm signal very soon, of short duration warning inspection signal may not be by timely discovery, so introduced monostable circuit again at this; When fault-signal produces, can trigger monostable circuit, its state is held; This monostable circuit can be passed through reset switch, after fault is got rid of, fault-signal is resetted.
2, the characteristics of module
1. circuit is succinct
The utility model patent has adopted pure hardware to form.Debugging is simple, can accomplish debugging smoothly as long as have the personnel on primary electron basis.Production cost is lower simultaneously, has good cost performance.Be fit to mass production.
2. working stability
Owing to adopt pure hardware mode, so its antijamming capability is strong.Has higher job stability.The electronic switch (MOSFET) that switch adopts, its switch life is far longer than the mechanical switch of relay class.Adopt electronic switch also to greatly reduce the power consumption of driving circuit simultaneously.
3. improved the charging performance of charger:
Turn-off the effect of charge circuit because this circuit has the fixed cycle short time, thereby make the charged state of charger be similar to the pulse charge mode.This mode can significantly reduce the heat accumulation of battery.Thereby the recovery and the serviceable life that increases battery that help the capacity of battery.
The beneficial effect of the utility model is to adopt a kind of inspection on-off mode of following, and has solved and should charge to battery, simultaneously also will be through the voltage detecting mode to the battery online contradiction that detects whether.Adopt the mode of electronic switch, improved reliability of products greatly, also reduced the power consumption of module simultaneously.This module have circuit succinct, be easy to debug, the characteristics of low-cost, working stability.
