Detailed Description
The technical solutions in the embodiments of the present invention are clearly and completely described below with reference to the drawings of the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
It will be understood that the terms "comprises" and/or "comprising," when used in this specification and the appended claims, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof.
It is also to be understood that the terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used in the specification of the present invention and the appended claims, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. Unless stated to the contrary, use of directional terms such as "upper, lower, left, right" are generally defined with reference to the drawing plane directions of the corresponding drawings of the present disclosure, and "inner and outer" refer to the inner and outer of the corresponding component profiles.
As shown in fig. 1, the pseudo battery power supply system architecture of the present invention mainly includes: the device comprises a false battery power supply module, a power supply selection module, a power supply end head manager, an information memory and a user display interface.
The power supply terminal manager is responsible for the distribution of power supply terminal authorities when multiple power supply terminals work, and the embodiment is described by a scheme of distributing two power supply terminals. When the A port or the B port detects that equipment is inserted, the power supply authority is distributed to the corresponding power supply end, and when the A port and the B port detect that the equipment is inserted, the power supply authority is controlled by the power supply end manager to provide fixed safe power supply output.
FIG. 2 illustrates a flow diagram for parameterizing management behavior of a power head manager in accordance with the disclosed embodiments. The parameter configuration process comprises the following steps:
s1, the user display interface may have a variety of configurations and displays by setting parameters to configure management behavior of the power tip manager.
S2, common parameters applicable to all power supply terminals managed by the power supply terminal manager are set. The generic parameters can be configured by the operator. For example, a minimum supply current of 2A or 5A, etc., compatible with all supply terminals.
And S3, setting intelligent identification parameters for all power supply terminals, thereby realizing intelligent identification operation. The smart identification parameter may be the maximum output power that can be achieved by each power supply terminal, for example, the maximum output power of the power supply terminal port a is 44W, and the maximum output power of the power supply terminal port B is 60W.
The Smart Authent operation has two options: opening the power supply terminal and closing the power supply terminal. The smart identified parameters are recorded in a power supply tip universal parameter table, which is stored in an information memory and set via a user display interface. If the "open power terminal" option is indicated via step S3, the power terminal manager will perform a performance test on a plurality of dummy battery power units after opening the corresponding power terminal, and display the dummy battery power units with superior test performance via the user display interface, the performance test may be performed periodically or in a dynamic manner.
If the "power head off" option is indicated via step S3, the power head manager will not conduct performance tests on multiple dummy battery power cells. In addition, the power tip manager will not use the user display interface to display any results from the test.
And S4, setting intelligent conversion parameters for all the power supply terminals, thereby realizing the intelligent conversion operation of all the opened power supply terminals. The intelligent switching operation is used to switch the service line to the preferred line. For example, in fig. 1, the two power supply terminals, port a and port B, extend to two sides respectively. The intelligent conversion operation has two options: the switching option and the holding option, and accordingly, the intelligent switching parameter comprises a switching parameter and a holding parameter.
If the switch parameter is set as indicated in step S4, then the smart verify operation in step S3 will set all power tips to "open power tips" first, and in the "open power tips" state, the power tip manager will perform the switch option in step S4 to automatically switch the service line to the preferred line if the preferred line is different from the current service line.
Preferably, the power tip manager can intelligently switch lines and also notify the operator of this switch. When a smart switching operation occurs, notification may occur through the use of a pop-up window on the user display interface.
If "power supply tip off" is indicated in step S3, the smart switching operation in step S3 is disabled. The power tip manager does not select any line that is different from the current service line.
And S5, setting the specific power supply terminal parameters through the user display interface, and configuring the specific power supply terminal parameters for the power supply terminal manager. The specific power supply terminal parameters, which may be configured by the operator, affect the preferred circuitry for the intelligent switching of step S4.
The particular power head parameters are stored in a particular parameter table, which may be stored in an information store and accessible by a power head manager. Three specific power supply end parameters are set in the specific parameter table: preferred parameters, general parameters, query selection parameters.
If the preferred parameter is set, the power head manager will always switch when this line is the preferred line. If the general parameter is set, the power tip manager will not switch to the preferred line. If the query selection parameter is set, the power tip manager will query the operator whether to switch. Based on the operator response, the power tip manager will operate.
S6, the power supply terminal manager is updated by the parameters set in steps S1-S5. The parameters are used to configure the power head manager and remain unchanged until step S1 is performed again to set the parameters.

In a preferred embodiment, the linearly supplemented auxiliary power supply in the fixed power supply mode has an adapter for connecting to an external ac power supply and converting the ac power to dc power for use by the dummy battery power supply unit, and receives the dc power converted by the adapter and supplies the dc power to the output circuit of the dummy battery power supply unit.
In a preferred embodiment, the output voltage of the linearly-supplemented auxiliary power supply adopting the programmed power supply mode is controlled by a voltage self-controller, and the structural schematic diagram of the voltage self-controller is shown in fig. 3.
The voltage self-controllers include a buck self-controller and a boost self-controller, which are connected to each other in a cascade to provide an output voltage having a target value. The voltage self-controller receives a voltage between the voltage output terminal of the auxiliary power supply and the voltage return terminal of the auxiliary power supply, and responsively generates an output voltage between the voltage output terminal of the voltage self-controller and the voltage return terminal of the auxiliary power supply.
