Under, other accompanying drawings can be obtained with the structure according to these accompanying drawings.
Fig. 1 is structure principle chart of the present utility model.
The realization of this utility model purpose, functional characteristics and advantage will be described further in conjunction with the embodiments referring to the drawings.
Specific embodiment
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the present utility model, rather than all
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not making creative work premise
Lower obtained every other embodiment, belongs to the scope of this utility model protection.
If it is to be appreciated that relate in this utility model embodiment directivity indicate (such as upper and lower, left and right, it is front,
Afterwards ...), then directionality indicates to be only used for explaining relative between each part under a certain particular pose (as shown in drawings)
Position relationship, motion conditions etc., if the particular pose changes, directionality indicates also correspondingly to change therewith.
In addition, if the description of " first ", " second " etc. is related in this utility model embodiment, should " first ", " the
Two " description etc. is only used for describing purpose, and it is not intended that indicating or implying its relative importance or implicit indicate indication
The quantity of the technical characteristic for showing.Thus, define " first ", the feature of " second " can be expressed or implicitly include at least one
Individual this feature.In addition, the technical scheme between each embodiment can be combined with each other, but must be with ordinary skill
Personnel can be implemented as basis, will be understood that this technical side when the combination appearance of technical scheme is conflicting or cannot realize
The combination of case is not present, also not within the protection domain that this utility model is required.
The utility model proposes a kind of power-down protection apparatus.
Refer to Fig. 1, a kind of power-down protection apparatus of the present utility model, including power module, voltage acquisition module, voltage
Comparison and alarm module, ephemeral data memory module, non-volatile memory modules, main system processing module.Wherein power module
Including external power supply and accumulation power supply, external power supply is in normal operating conditions, electric to main system processing module and energy storage respectively
Source powers, accumulation power supply in external power supply normal power supply in charge state, when external power supply power-off accumulation power supply to
Main system processing module is powered.The on off operating mode out-put supply collection signal of voltage acquisition module monitor in real time external power supply；
Power supply collection signal be less than given threshold, voltage ratio compared with and alarm module send power-off alarm signal；Ephemeral data memory module
Read the processing data of main system processing module；Non-volatile memory modules are in external power cut-off by main system processing module
Activation；After main system processing module receives power-off alarm signal, ephemeral data memory module and non-volatile memory modules are sent out
Go out store instruction, non-volatile memory modules read the data of ephemeral data memory module and permanently preserved.
, in the state of external power supply normal work, external power supply is to main system processing module and storage for power-down protection apparatus
Energy power supply normal power supply, because accumulation power supply is lithium battery or accumulator, therefore accumulation power supply is in external power supply normal power supply
In continual charged state.When the unexpected power-off of external power supply, external power supply will be switched off to main system processing module and
The power supply of accumulation power supply, accumulation power supply will become discharge condition from charged state conversion, and to main system within the regular hour
Processing module is powered.Because voltage acquisition module is electrically connected with external power supply, after external power supply disconnects powers, external power supply
Voltage gradually decay, voltage acquisition module by capture external power supply off-state and to voltage ratio compared with and alarm module send
Power supply gather signal, voltage ratio compared with and alarm module by the power supply for getting gather signal with set threshold value be compared, when
Power supply collection signal provide with regard to supply voltage be less than given threshold when, voltage ratio compared with and alarm module can determine that external power supply
Brownout simultaneously sends power-off alarm signal to main system processing module, and main system processing module is obtaining power alarm signal
Afterwards, the ephemeral data memory module electrically connected with main system processing module and non-volatile memory modules are activated and sends storage
Instruction, because ephemeral data memory module is random access memory, if in the process that is gradually lowered of voltage of external power supply
In read not in time and be stored in the data of ephemeral data memory module, then data can be caused permanently to lose, therefore at main system
Reason module instruction non-volatile memory modules read instant data to ephemeral data memory module, and by the data for reading and
When be stored in non-volatile memory modules, after can reclosing for external power supply, carry out providing data backup during data recovery.
In embodiment of the present utility model, power-down protection apparatus are enabled standby electricity after external power cut-off, in time
Source, and backed up by timely data exchange, be prevented effectively from the technical problem of loss of data is caused because of power failure.
This utility model also proposed a kind of cash register system, and the cash register system applies the power down in above-described embodiment
Protection device, can avoid power failure from causing the loss of cashier's machine present deal data.
Preferred embodiment of the present utility model is the foregoing is only, the scope of the claims of the present utility model is not thereby limited,
It is every under inventive concept of the present utility model, the equivalent structure made using this utility model description and accompanying drawing content is become
Change, or directly/be used in indirectly other related technical fields and be included in scope of patent protection of the present utility model.
