Embodiment
The technical solution of the utility model is described in detail below in conjunction with drawings and Examples:
The utility model is in prior art, USB power supply can not concentrate the problem of power supply in enormous quantities, a kind of centralized USB electric power system is provided, comprise power input, power transfer module one, charging module, power transfer module two and USB output, described power input is connected with power transfer module one, power transfer module one is connected with power transfer module two and charging module respectively, and described power transfer module two is connected with USB output, and described USB output is at least one.Power not only can to multi-user simultaneously, and can continue when civil power power-off to the electricity of USB power consumption equipment for a period of time.
Embodiment
The centralized USB electric power system of this example, as shown in Figure 1, comprise power input, switch module 1, input power power detection module 2, power transfer module 1, charging module 4, switch module 25, charge capacity detection module 6, power transfer module 27, switch module 38, USB output 9 and power supply detection module 10.Described power input is connected with power transfer module 1 by switch module 1; Power transfer module 1 is connected with power transfer module 27 and charging module 4 respectively, and described power transfer module 27 is connected with USB output 9; Input power detection module 2 of powering is in parallel with power transfer module 1; Power transfer module 1 is connected with charging module 4 by switch module 25; Charge capacity detection module 6 is in parallel with charging module 4, concrete, and charge capacity detection module 6 comprises electric power detection unit and indicating member, and described electric power detection unit is in parallel with charging module 4, and described indicating member is connected with electric power detection unit; Power transfer module 27 is connected with USB output 9 by switch module 38; Power supply detection module 10 is in parallel with USB output 9.Wherein, USB output 9 is at least one, and with power supply detection module 10 one_to_one corresponding.Wherein, power transfer module one turns 12V DC Module for 220V.Described power transfer module two turns 5V module for 12V.
In this example, in order to improve versatility and the maintainability of native system, the electronic component of native system inside adopts existing integrated IC.
Power input is accessed 220V alternating current, open switch module 1 and make civil power enter native system inside, if now civil power has electricity, input power detection module 2 of powering sends prompting message, if without electricity, input power is powered detection module 2 not conduct.
Civil power turns 12V DC Module 3 through 220V and is converted to 12V direct current of voltage regulation, charges for charging module 4 in one road, and the power supply that a road turns 5V module as 12V uses.During to charging module 4 charged electrical, need closed accumulator cell charging and discharging switch, i.e. switch module 25, the charge condition of charge capacity detection module 6 pairs of charging modules checks simultaneously, and inspection situation is shown to user by the indicating member in charge capacity detection module 6.It is that USB output 9 can for identifying with the 5V voltage received for user by voltage transitions that 12V turns 5V module, user to need mobile terminal device by USB connecting line in use to USB output 9, then USB power switch is pressed, i.e. switch module 38, USB detection module 10 of powering will detect the voltage charge condition of USB access device, power supply detecting unit and power supply indicating member is comprised in detection module 10, after power supply detecting unit detects the voltage charge condition of access device, user is shown to by power supply indicating member, such as if so the change by USB indicator light 12 is informed by charging be still full of electricity with the charging stage.When mains failure, by the charge and discharge switch of closed charging module 4, i.e. switch module 25, use charging module 4 to customer power supply.The accumulator cell charging and discharging switch of charging module 4, i.e. the switch module 25 closed effect effectively can playing filtering and voltage stabilizing for a long time.
