Embodiment
Please refer to Fig. 1, it illustrates is circuit block diagram according to a preferred embodiment of the present invention.Battery charger 108 comprises a conventional batteries charging device 102 and a supervising device 104.Wherein, conventional batteries charging device 102 couples this supervising device 104.
Behind power supply input conventional batteries charging device 102, begin rechargeable battery is charged.In order to keep rechargeable battery, must continue rechargeable battery is charged at any time at high-energy and high-tension state.Therefore, whether supervising device 104 real-time monitoring power supplies import conventional batteries charging device 102, normally carry out so that keep the charging action.If power supply is not imported conventional batteries charging device 102, then supervising device can be exported alerting.When generator starting, must guarantee that rechargeable battery can supply enough energy, to drive generator 106.Therefore, when finding that as if supervising device the charge circuit of charging current opens circuit, then export alerting.
Please merge with reference to Fig. 2, what it illustrated is the refinement circuit block diagram of Fig. 1 embodiment.Supervising device 104 comprises power supply checking circuit 202, current-sensing circuit 206 and man-machine interface 208.Wherein, power supply checking circuit 202 comprises relay 214, fuse 210 and fuse 212.Wherein, current-sensing circuit 206 comprises fuse 220 and internal lock switch 222.Wherein, man-machine interface 208 comprises field digital controller 226 and monitoring host computer 228.Conventional batteries charging device 102 electric property coupling power supply checking circuits 202.Moreover, current-sensing circuit 206 electric property coupling conventional batteries charging devices 102.Moreover, man-machine interface 208 electric property coupling power supply checking circuits 202 and current-sensing circuit 206.
Under the situation of normal operation, power supply is via power supply checking circuit 202 input transformers 230.At this moment, because relay 214 is an open-circuit condition, so field digital controller 226 can't detect any signal.Afterwards, power supply is through bridge rectifier 232 rectifications.Then, a power supply filter capacitor 234 of input and a voltage stabilizing diode 236 carry out filtering and voltage stabilizing.After above-mentioned alternating current was changed galvanic process and finished, direct supply charged to a rechargeable battery 218.In addition, the fuse 216 that comprises a reometer 238 and 30 amperes in the charge circuit of above-mentioned charging action.Wherein, reometer 238 can be monitored the running situation of charging device for the monitor staff.In addition, because generator starting momentary charge battery 218 can be exported powerful electric current, so but install fuse 216 prevent mean internal circuits and burn.In addition, the fuse 220 that fuse 216 parallel connections are 0.5 ampere is when the charging device normal operation, because the resistance value of fuse 220 (0.5 ampere) is much larger than fuse 216 (30 amperes), so most electric current can flow through fuse 216.Therefore, the loop of fuse 220 only has a little electric current to pass through.Moreover fuse 220 has a relation that is connected locking with an internal lock switch 222.That is when fuse 220 normal operations, internal lock switch 222 keeps open-circuit condition, makes field digital controller 226 can't detect any signal.Otherwise, when fuse 220 burns, trigger internal lock switch 222, cause internal lock switch 222 to produce closing motion and make field digital controller 226 detect a short circuit signal.
Under unusual situation, suppose the sudden outage of Utilities Electric Co., must activate generator this moment in real time.At first, because the power supply disappearance, so power supply checking circuit 202 does not have the power supply input.Therefore, because relay 214 transfers short-circuit condition to, so field digital controller 226 detects a short circuit signal.Then, field digital controller 226 sends a unusual alerting.At last, alerting of monitoring host computer 228 outputs is notified the monitor staff.On the other hand, after generator starting was finished, conventional batteries charging device 102 was immediately to rechargeable battery 218 a large amount of rapid charges, and the powerful electric current of its generation opens circuit because the loop produces, so electric current will transfer inflow fuse 220 when burning fuse 216.Afterwards, because the anti-flow valuve of fuse 220 only is 0.5 ampere, so fuse 220 can burn.Then, because fuse 220 burns,, make locking switch 222 generation closing motions and field digital controller 226 detect a short circuit signal so trigger internal lock switch 222.At last, alerting of monitoring host computer 228 outputs is notified the monitor staff.
Comprehensively above-mentioned, the present invention proposes a kind of battery charger monitoring circuit, is applicable to generator, diesel oil fire extinguishing pump etc.When needs activate generator, can guarantee that the electric energy of rechargeable battery maintains the state of the high electric energy of high voltage.In addition, after generator activates, when finding that conventional batteries charging device charging current is burnt inner fuse, more can send alerting in real time, notify the monitor staff to go to processing, to strive for servicing time.Therefore, make generator, diesel oil fire extinguishing pump etc. be brought into play the usefulness of expection, reduce time and monetary loss because of power breakdown caused.
Above-mentioned disclosed diagram and explanation only are a preferred embodiment of the present invention, be not in order to qualification the present invention, so protection scope of the present invention are as the criterion with claims.
