Description
Technical field
The present invention is applied to the adapter of electronic equipment, the adapter of particularly in case of emergency powering.
Background technology
Power supply adaptor becomes power electronic equipment equipment, and namely civil power (AC high voltage) to be converted to low-voltage dc voltage for electronic equipment by power-switching circuit and provides stable power supply by power supply adaptor.In order to tackle the situation of the unexpected power-off of civil power, occurred the adapter with battery in the market, can prevent when civil power power-off, adapter still can be powered for electronic equipment.But because the method has a drawback at present, cannot cannot continue as its power supply by electronic device adapter when battery exhausts substantially, so when running down of battery, electronic equipment still there will be the situation of unexpected power-off.Having of this situation may cause expendable injury to electronic equipment.In order to tackle this situation, just needing to occur that one is when using battery adapter, providing real-time battery electric quantity to detect and carrying out corresponding protection mechanism in order to electronic equipment, carrying out power-off operation when battery electric quantity is low as carried out, and carry out data protection storage.
Summary of the invention
Be that electronic equipment carries out power-down notice for tackling in prior art when adapter cannot be powered; for solving the problem; before the invention provides a kind of power-off, electronic device carries out shutdown protection mechanism, and for achieving the above object, technical scheme of the present invention realizes like this.
A kind of electricity supervisory control system of adapter, comprise alternating current input module, rectification circuit module, battery management module, battery module, booster circuit module and output switching circuit, Power Entry Module, output switching circuit is according to the path/open circuit conditions of alternating current, Switching power input pattern, when alternating current power-off, by battery module, after booster circuit module boosting process, through power supply output module to power terminal equipment, described battery module is in real time to battery management module feedback information about power, described battery module feeds back the warning information of electricity lower than preset value to battery management module, described battery management module sends the request instruction of closing device to the terminal equipment be connected with described system according to described warning information.
The power supply output module of described system and terminal equipment are connected by data wire and charge, and the request instruction of closing device is sent to terminal equipment by data wire.
Compared with prior art; beneficial effect of the present invention is; when can be implemented in civil power power-off by implementing technical scheme of the present invention; it can be still power electronic equipment; real-time display battery electric quantity state; carry out reporting to the police and reporting battery electric quantity to electronic equipment after electricity is lower than certain value, electronic device is carried out power-off shutdown protection and is operated and realize the operation of data storage protection.

Fig. 2 is the structural frames line schematic diagram of Fig. 1 electricity early warning.
Embodiment
Below in conjunction with accompanying drawing, embodiments of the invention are described in detail, but the multitude of different ways that the present invention can be defined by the claims and cover is implemented.
Please refer to Fig. 1, Fig. 1 is the electricity real-time monitoring circuit structured flowchart of a kind of adapter of the present invention, in detail in this figure, entering the civil power of adapter circuit, is generally the alternating current of 220V, flow through rectification circuit module, after rectification circuit, filter circuit, the civil power of 220V is converted to the direct current of 12V or 9V or 5V wherein a kind of specification, concrete specification is determined according to adapter, under charge mode, the direct voltage being rectified into appropriate size is directly charged to terminal electronic device by voltage output module.
In another mode, low-voltage DC after rectification is through main control unit, main control unit effect is the state controlling battery charging and monitor whole circuit, by connecting the voltage/current state of sensing circuit real-time monitoring circuit in circuit, under normal mode, by the current storage of main control unit at battery unit.Because terminal equipment is different to the requirement of supply voltage, the power supply that battery unit stores stores with low pressure, and therefore after civil power power-off, the voltage that battery unit is carried to terminal equipment need carry out Voltage Cortrol through booster circuit module, according to alternating current whether power-off, switch the different power supply way of outputs, when city's electric pathway, control power supply switch circuit, the power supply adopting high pressure to turn low pressure exports, when civil power power-off, control power supply switch circuit, adopt power boost power supply to export.
In the present embodiment, system is in particular in, by power on/off according to civil power of output switching circuit, and Switching power output mode; When civil power power-off, output switching circuit switches to the pattern of being powered by battery module; The electric current that battery module exports carries out boosting process through booster circuit module; Battery module is in real time to the signal of battery management module feedback state of charge; Battery module obtains the electricity of battery module lower than after the alarm signal of preset value, is sent the request of closing device by power supply output module to terminal equipment.
Specifically, output switching circuit detects that civil power is disconnected, commutation circuit, adopt and powered by battery module, the power supply way of output of boosting, continue to charge to mobile phone, in charging process, the state of charge of battery management module Real-Time Monitoring battery module, collect power state information, when the electricity of battery module is lower than the value preset, battery management module collects warning information, the electricity warning information of data line transfer battery module of adapter by being connected with terminal equipment, after receiving warning information, the stop terminal equipment of running background of terminal equipment by pre-setting.
Specifically, under normal circumstances, adapter is electrically connected with city by diplopore or porous socket, whether output switching circuit detects has civil power to access, control the state that electrical source exchange unit is power on/off according to civil power, under civil power "on" position, control power supply switch circuit, alternating current is converted to low-voltage DC by rectification module by adaptor interface, directly be communicated with mobile phone on the one hand, charging action is carried out to mobile phone, on the other hand, in charging process, battery management circuit module manages battery charging, according to the circuit state of battery module, whether battery module is charged, when not charging, automatic cut-out is to the electric current of adapter battery module, electricity as battery module is not enough, then start the charging to battery, simultaneously, Real-Time Monitoring battery electric quantity state, read battery level information, when information about power display is full of, then stop charging, enter pattern to be charged.
These are only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
