Abstract
The utility model discloses an entry control system is failed to mainboard four ways power, including be used for discerning the electric access state power identification module, be used for control will power after power identification module discernment preface in proper order converts the switching of power module of VDC power, the double cell module of charging into, power identification module includes four ways power source and inserts the signal modules that listens behind the power, two battery module are according to power identification module's the instruction action of charging. The utility model discloses not only support many powers, realized seamless handover between the power moreover, satisfy the demand of system under different power environment, the double cell provides longer time of endurance for the system.
Description
Technical field
The utility model relates to a kind of mainboard four-way power supply input control system.
Background technology
In daily life, conventional desktop computer belongs to single supply system, and notebook computer belongs to double power-supply system.Desktop computer is converted into civil power by AT and ATX power supply the power supply of desktop computer mainboard needs; Notebook computer is converted into civil power by adapter the power supply of notebook mainboard needs, and provides charging to Notebook Battery, and during battery individualism, notebook computer is battery-powered.Single supply system does not relate to the switching of power supply, and double power-supply system is the switching of AC AC power and battery.Single supply system power supply is single, and without backup battery, when there is powering-off state, system cannot work.Double power-supply system is a many battery, although many a kind of power supply options, has its weak point.Such as when there is no AC AC power and high to battery life requirement, double power-supply system cannot satisfy the demands.
Utility model content
The purpose of this utility model be for frequent default AC AC power and high to battery life requirement when, a kind of mainboard four-way power supply input control system is provided.
In the utility model, four-way power supply refers to: AC power (AC), DC power supply (DC), the first battery (BAT1) and the second battery (BAT2).
The technical solution of the utility model is as follows: a kind of mainboard four-way power supply input control system, comprises the power supply identification module for identifying plant-grid connection state, the electrical source exchange module being sequentially converted to VDC power supply for controlling the power supply after by the identification of described power supply identification module, a double cell charging module; Detection signal module after described power supply identification module comprises four-way power supply interface and inserts power supply; Described double cell module carries out charging action according to the instruction of power supply identification module.
Preferably, described input control system also comprises double cell, is respectively the first battery and the second battery, is connected with the two-way in four-way power supply interface; Double cell when electricity less than, can by access AC, charge through double cell module, sufficient at electricity, in the non-existent situation of AC and DC, can discharge after the identification of power supply identification module, be VDC power supply be system power supply through electrical source exchange module converts thereupon.
In the utility model, when double cell charging module is included in AC existence and battery electric quantity underfill, preferentially to the first battery charging, then to the second battery charging.
Adopt such scheme, the utility model not only supports many power supplys, and achieves seamless switching between power supply, meets the demand of system under different electrical power environment; Double cell is that system provides longer cruising time.

Fig. 1 is configuration diagram of the present utility model;
Fig. 2 is the circuit diagram of the utility model power supply identification module;
Fig. 3 is the circuit diagram of the utility model electrical source exchange module;
Fig. 4 is the circuit diagram of the utility model double cell charging module.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
With reference to shown in Fig. 1, the utility model provides a kind of mainboard four-way power supply input control system, comprises the power supply identification module for identifying plant-grid connection state, the electrical source exchange module being sequentially converted to VDC power supply for controlling the power supply after by the identification of described power supply identification module, a double cell charging module; Detection signal module after described power supply identification module comprises four-way power supply interface and inserts power supply; Described double cell module carries out charging action according to the instruction of power supply identification module.
Four-way power supply is after identification and switching, and converting the VDC that system needs to, is system power supply.
As shown in Figure 2, power supply identification module of the present utility model comprises AC power interface and AC_IN signal, DC power supply interface and DC_IN signal, battery 1 interface and BAT1_IN signal, battery 2 interface and BAT2_IN signal, four-way power supply is while insertion power interface, circuit for detecting is according to AC_IN, DC_IN, BAT1_IN, BAT2_IN obtain power supply status.
As shown in Figure 3, electrical source exchange module is the emphasis of four-way power supply system, and the logic of electrical source exchange can be divided into three major types, totally ten five kinds of situations (see table 1):
The logical table that table 1 four-way power supply system power supply switches
For AC+DC+BAT1+BAT2 situation, Power supply order be AC preferentially, DC and BAT2, last BAT1 successively.When power supply circuits detect AC_IN signal, cut off the power supply of DC, BAT1 and BAT2, system is powered separately by AC; When power supply circuits detecting is less than (removing AC power supplies) during AC_IN signal, power supply circuits are switched to DC and power separately.
As shown in Figure 4, double cell charging module is battery powered guarantee, and the order of battery charging is that BAT1 is preferential, secondly BAT2.Battery only when AC and electricity deficiency, just opens charge function, has three kinds of situations (see table 2):
Show the charging order table in 2AC and the not enough situation of electricity
Deposit in case in AC power supplies, BAT1 and BAT2 exists simultaneously, and when electricity is not enough, preferential BAT1 charging, after BAT1 is full of, BAT2 starts charging; During BAT1 and BAT2 individualism, directly charge.
These are only preferred embodiment of the present utility model, be not limited to the utility model, all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection range of the present utility model.
