Power supply is called the heart of communication system, for system provides power-electric energy endlessly, and storage battery is as the back-up source of communication system, when outer electric fault or other reason cause power failure, storage battery ensures communication system uninterrupted power supply, guarantees that unimpeded unique of network is also one last defence line, its safe operation for the reliability of communication system and fail safe self-evident.
The backup battery used in communications equipment room or mobile base station at present, great majority are valve controlled sealed lead-acid accumulator (Valve Regulated Lead-Acid Battery), are called for short VRLA battery.Relative to traditional lead-acid battery, its non-maintaining property, no leakage, more than the 10 year good characteristics such as life-span, compact conformation minimum without acid mist, self discharge, make them after the 90's of 20th century, be equipped on the communications equipment room base stations such as domestic electric power, communication, railway in a large number.
The online discharge scheme of current most of storage battery, mainly contains following two kinds of modes:
One is directly connected in series boosting unit between storage battery exports with Switching Power Supply, although this scheme can be implemented in line electric discharge, has been connected in series extra circuit in the power supply system, added fault point to system, is difficult to ensure being perfectly safe of power-supply system;
Another kind of common approach first storage battery is stripped out from power-supply system, then utilizes direct-flow inverter to discharge to storage battery as the load of storage battery, inversion exported and is linked on load equipment, to reach the object of energy recovery.This scheme has in fact been not really online electric discharge, just can realize energy recovery, and needs manually storage battery to be stripped out, and adds the workload of staff.
Utility model content
In order to solve the problems of the technologies described above, it is simple that the purpose of this utility model is to provide a kind of structure, and the online discharge system of a kind of storage battery that fail safe is higher.
The technical scheme that the utility model adopts is:
The online discharge system of a kind of storage battery, comprise multiple batteries, the collecting unit corresponding with batteries quantity, direct-current switch power supply, load equipment and server, the output of described direct-current switch power supply is connected with the input of load equipment, described batteries is connected with direct-current switch power supply and collecting unit respectively, described collecting unit is connected with server, described direct-current switch power supply is provided with control interface, and described direct-current switch power supply is connected with server by control interface.
As further improvement of the utility model, between described direct-current switch power supply and batteries, be also connected with fusible link.
As further improvement of the utility model, described collecting unit comprises voltage acquisition module, current acquisition module, internal resistance measurement module and battery temperature acquisition module, described batteries is connected with voltage acquisition module, current acquisition module, internal resistance measurement module and battery temperature acquisition module respectively, and described voltage acquisition module, current acquisition module, internal resistance measurement module are all connected with server with battery temperature acquisition module.
As further improvement of the utility model, described direct-current switch power supply is provided with control inputs panel.
The beneficial effects of the utility model are:
A kind of storage battery of the utility model online discharge system structure is simple, without the need to connecting dummy load, without the need to sealing in circuit in the power supply system, greatly reduce fault point, the utility model utilizes the adjustable characteristic of direct-current switch power supply and actual loading to discharge online, and gathers battery information by collecting unit and transfer to server and show, and facilitates the state of staff's real-time monitoring battery in discharge process, effective raising equipment safety, improves maintenance efficiency greatly.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further:
Fig. 1 is the functional-block diagram of the online discharge system of a kind of storage battery of the utility model;
Fig. 2 is the functional-block diagram of the online discharge system collecting unit of a kind of storage battery of the utility model.
Embodiment
With reference to figure 1, the online discharge system of a kind of storage battery of the utility model, comprise multiple batteries, the collecting unit corresponding with batteries quantity, direct-current switch power supply, load equipment and server, the output of described direct-current switch power supply is connected with the input of load equipment, described batteries is connected with direct-current switch power supply and collecting unit respectively, described collecting unit is connected with server, described direct-current switch power supply is provided with control interface, and described direct-current switch power supply is connected with server by control interface.
Be further used as preferred embodiment, between described direct-current switch power supply and batteries, be also connected with fusible link.
With reference to figure 2, be further used as preferred embodiment, described collecting unit comprises voltage acquisition module, current acquisition module, internal resistance measurement module and battery temperature acquisition module, described batteries is connected with voltage acquisition module, current acquisition module, internal resistance measurement module and battery temperature acquisition module respectively, and described voltage acquisition module, current acquisition module, internal resistance measurement module are all connected with server with battery temperature acquisition module.
Be further used as preferred embodiment, described direct-current switch power supply is provided with control inputs panel.
Specific embodiment is as follows:
Suppose that power-supply system is configured with two group storage batteries, need when wherein a group storage battery A discharges online,
Operating procedure is as follows:
1, the fusible link of storage battery B is disconnected, at this moment storage battery B and system depart from, storage battery A then on-line operation, and Switching Power Supply carries out floating charge to storage battery A, even if at this time mains failure, because storage battery A completely fills for subsequent use online, load equipment can not power down;
2, by panel or the control interface of direct-current switch power supply, direct voltage output is adjusted to final discharging voltage;
3, final discharging voltage forces down than storage battery full charge, but can meet the minimum power supply needs of load equipment.Now because the magnitude of voltage (final discharging voltage) that Switching Power Supply exports exports than low than storage battery A voltage, therefore, storage battery A starts to start electric discharge to load equipment, even if at this moment batteries A off-capacity or battery failures cause voltage to decline rapidly, because Switching Power Supply is in the state of working online, can power for load equipment, can not cause system power failure, power-supply system is safe;
4, the discharge process of collecting unit Real-time Collection storage battery A, arrives when staff views discharge off condition, just can stop by controlled discharge at once;
5, by panel or the control interface of direct-current switch power supply, Switching Power Supply is exported and is reset to automatic charging pattern, the batteries A completing electric discharge is charged, until batteries A is full of, till being converted to floating charge pattern;
6, close the fusible link of storage battery B, completes the discharge operation of batteries A.
More than that better enforcement of the present utility model is illustrated, but the utility model is created and is not limited to described embodiment, those of ordinary skill in the art also can make all equivalent variations or replacement under the prerequisite without prejudice to the utility model spirit, and these equivalent distortion or replacement are all included in the application's claim limited range.
