Abstract
The utility model discloses a direct-current power supply mechanism having a stand-by power source. The direct-current power supply mechanism comprises an AC/DC converting module, a control module, a DC/DC converting module, and a electric storage module, wherein the above module are connected in sequence, the AC/DC converting module is connected with commercial power, the DC/DC converting module is connected with working equipment, the electric storage module is connected with the control module to be under charging and discharging control of the control module. Compared with the prior art, the direct-current power supply mechanism of the utility model has the beneficial effects that: firstly, the direct-current power supply mechanism can be automatically switched to the electric storage module for supplying electricity to the working equipment when commercial power fails, and the continuity of electricity supply is guaranteed by using the electric storage module; secondly, the overall structure of the direct-current power supply mechanism is simple, and compact and the repair and maintenance are facilitated by adopting the modularized design; and finally, the usage is safe, stable and reliable, the cost is reduced, and the benefits are enhanced.
Description
Technical field
The utility model relates to a kind of DC power supply mechanism, belongs to the dc suppling equipment technical field, refers in particular to a kind of DC power supply mechanism that possesses back-up source.
Background technology
At present; The DC power supply mechanism that is used for direct current supply on the market generally realizes through the AC/DC modular converter; And, all need set ups power usually for the working equipment that needs carry out data protection, so that losing under the civil power situation; Utilize ups power that the data that needs keep are promptly deposited, guarantee can not lose or corrupt data because of having a power failure suddenly.But working equipment sets ups power, has not only increased the equipment funds input, and the limited inner space of the equipment that taken is caused and used inconvenience, and has increased the fault point of whole set equipment, has increased maintenance difficulties.
The utility model content
The purpose of the utility model is to overcome shortcoming of the prior art with not enough, a kind of safety simple and compact for structure, easy to use is provided, cost is low and the DC power supply mechanism that possesses back-up source that do not take up space.
To achieve these goals, the utility model is realized according to following technical scheme:
A kind of DC power supply mechanism that possesses back-up source includes AC/DC modular converter, control module and DC/DC modular converter, and above-mentioned module connects in regular turn, and the AC/DC modular converter connects civil power, and the DC/DC modular converter connects working equipment; Further, also include power storage module, said power storage module is connected with control module, discharges and recharges control to accept control module.
Further, be provided with relay switch between said control module and the power storage module.
Further, said control module is communicated by letter with working equipment and is connected.
Further, said DC/DC modular converter includes several DC/DC modular converter unit that works alone.
The utility model compared with prior art, its beneficial effect is:
1, utilizes power storage module, when the civil power dead electricity, can automatically switch to power storage module working equipment is supplied power, ensure the continuity of power supply;
2, adopt modularized design, the overall structure compact makes things convenient for repair and maintenance;
3, safe in utilization reliable and stable, reduced cost, improved benefit.
In order to understand the utility model more clearly, below accompanying drawings is set forth the embodiment of the utility model.
Description of drawings
Fig. 1 is that the circuit of the utility model connects sketch map.
Embodiment
As shown in Figure 1; The said DC power supply mechanism that possesses back-up source of the utility model includes AC/DC modular converter, control module and DC/DC modular converter, and above-mentioned module connects in regular turn; And the AC/DC modular converter connects civil power, and the DC/DC modular converter connects working equipment.Further, also include power storage module, said power storage module is connected with control module, discharges and recharges control to accept control module.
As the preferred version of present embodiment, be provided with relay switch between above-mentioned control module and the power storage module, and communicate by letter with working equipment and to be connected; Above-mentioned DC/DC modular converter includes several DC/DC modular converter unit that works alone.
The operation principle of the utility model is described below: when the civil power normal power supply; Civil power is earlier through the AC/DC modular converter; Convert the 220V AC power into DC power supply, the DC power supply after the conversion is given control module, and control module utilizes this DC power supply to give each DC/DC modular converter unit and working equipment; Thereby working equipment is carried out the multiple voltage power supply; Control module utilizes this DC power supply that power storage module is discharged and recharged control simultaneously, and meanwhile, control module also detects the mains-supplied state in real time; After the civil power dead electricity, control module drives the relay switch action, switches to the power storage module powering mode; Transmit the civil power state information simultaneously to working equipment; And then to the related data processing of promptly depositing, after data were preserved, working equipment sent the outage control command to control module again; Cut off back-up source, the working equipment shutdown.
The utility model is not limited to above-mentioned execution mode; If spirit and scope that the various changes or the modification of the utility model do not broken away from the utility model; If these are changed and modification belongs within the claim and equivalent technologies scope of the utility model, then the utility model also is intended to comprise these changes and modification.
