Abstract
The utility model discloses a high-efficiency building intercommunication standby power supply system, which comprises a power supply system and an intercommunication system. The power supply system comprises a power input interface, a voltage converting circuit, a charging circuit, a power output interface and a button switch, wherein the button switch is connected with a connected wire of the power input interface and an external 220V power supply, the power input interface is connected with the voltage converting circuit, the voltage converting circuit is connected with the charging circuit, and the charging circuit is connected with the power output interface; and the intercommunication system is an interphone, wherein the interphone with the power supply system is positioned in the same plastic housing, and is charged by the charging circuit. According to the utility model, the interphone is arranged in the standby power supply system, so that when the mobile interphone used by security staff is powered off, the standby power supply system can charge the interphone, and the interphone can continue to carry out intercommunication and conversation.
Description
Technical field
The utility model relates to a kind of backup power system, belongs to the electric device field.
Background technology
In building, intercom is that security personnel wait the most frequently used communication device of attendant, but the power-supply system in the building is not made at this immediate communication tool of intercom and is supported design, usually the power supply that need get back to room security when intercom does not have electricity charges, go on patrol the work meeting in this case and of short duration space occurs, brought potential safety hazard.
Summary of the invention
Defective at prior art, the utility model discloses a kind of backup power system of building talkback efficiently, not only can in charging, can proceed the intercommunication conversation for the mobile intercom that uses charges, guarantee the continuity of security, improved the building safety degree.
For achieving the above object, the utility model is achieved through the following technical solutions:
Efficient building talkback backup power system, comprise power-supply system and intercom system, described power-supply system comprises electric power input interface, voltage conversion circuit, charging circuit, electric power output interface and key switch, key switch is connected to being connected on the electric wire of electric power input interface and outside 220V power supply, the electric power input interface is connected to voltage conversion circuit, voltage conversion circuit is connected to charging circuit, and charging circuit is connected to the electric power output interface; Intercom system is intercom, is arranged in same plastic casing with power-supply system, and intercom is from the charging circuit power taking.
In said system, key switch plays the effect of switching circuit, and voltage conversion circuit is converted to the 5V direct current with the 220V alternating current, and charging circuit carries out rectification and clutter reduction to circuit, and the electric power output interface is the pure 5V direct current of output outwards.When the mobile intercom of Security Personnel's use cuts off the power supply, can be connected on the electric power output interface and charge, use built-in intercom to proceed conversation simultaneously, to guarantee the continuity of conversation.
Further, in order to satisfy the emergency application under the extensive power failure, rechargeable battery is installed also in the described power-supply system, rechargeable battery is connected to charging circuit.
When the long-time disconnection of 220V electric power input occurring, intercom is connected on the electric power output interface, charging circuit obtains electric power from rechargeable battery, can continue as it and charge; Simultaneously also rely on rechargeable battery work at built-in intercom in such cases.Behind the power recovery, be that rechargeable battery charges by charging circuit externally.
Further, for the ease of other user in the building, as cellphone subscriber's emergent charging, the electric power output interface has the two-way output, can support two equipment to charge simultaneously.
Description of drawings
Fig. 1 is the electrical block diagram of the utility model backup power system.
