Description
Technical field
The present invention relates to private content protection technique field, espespecially a kind of ring for keeping a diary.
Background technology
Many people have the custom kept a diary, generally it is not desirable that others sees, and existing diary otherwise
Exactly recorded with diary, be then encrypted with various locks, otherwise be exactly to be encrypted by computer editing, so
It is no matter writing or use computer editing during keeping a diary first and aforesaid way cannot accomplish privacy very
Mode, other people can steal a glance at from side, in addition, no matter existing cipher mode can be cracked, finally, keep a diary and generally require standby paper
Pen or computer be just capable of achieving to keep a diary, if do not carry corresponding tool cannot just keep a diary, therefore it is existing keep a diary mode without
Method is accomplished with note mode.
The content of the invention
To solve the above problems, the present invention provides a kind of ring for keeping a diary.
To achieve the above object, the present invention is adopted the following technical scheme that is：A kind of ring for keeping a diary, including with
In the ring-type finger ring of wearing, ring-type finger ring is provided with support, and upper and lower two accommodating chamber is divided into support, and upper accommodating chamber is used for boudle
Thing, is provided with control system in lower accommodating chamber, control system is electrically connected with power module, and described power module is used for control
System power supply；Described control system includes：

Instruction, then transmits commands to wireless communication module；
Step 5：Wireless communication module is uploaded to word and/or dependent instruction in Cloud Server, now may be used according to actual needs
So that status indicator lamp works, for representing that writing words have been uploaded successfully.
The beneficial effects of the present invention are：Profile of the present invention as common ring, it is compact it is attractive in appearance, be easy to carry about with one, can use
In decoration；Be worn over when on finger, only stroke need to be in the air carried out by finger and carry out writing mood, without rely on conventional keyboard,
The fixed input equipment such as microphone and board, without hand-held any sensing stage property, as long as in the inductive spacing of somatosensory device
It is interior to complete hand-written, freedom is write, operation is comfortable；Wireless communication module in rear ring is write to send to Cloud Server mood
Stored, when user wants to transfer diary, had access into Cloud Server by intelligent terminal, can into Cloud Server
To be online mode, or ad hoc mode, stroke is carried out by finger, other people cannot steal a glance at and obtain, only use
Person just knows that, even if others obtains ring also cannot therefrom obtain related personal information, all of record passes through Cloud Server
Stored, only user is logged in by account number cipher and can just obtained, other people can not easily know that user operates, so that
The probability that private content is seen by other people is greatly reduced, it is achieved thereby that reliably and efficiently protecting private content.
Used as a kind of worn ornament, user can carry with without forgeing ring simultaneously, when needs are for keeping a diary
When also without taking off, realize with writing with note.

Specific embodiment
Refer to shown in Fig. 1-3, the present invention on a kind of ring for keeping a diary, including for dress ring-type refer to
Ring, ring-type finger ring is provided with support, and upper and lower two accommodating chamber is divided into support, and control system is provided with lower accommodating chamber, and upper accommodating chamber is used for
Boudle thing, such as diamond, jewel, jade, control system are electrically connected with power module, and described power module is used to give
Control system is powered；Described control system includes：
Gesture recognition module, starts to write, terminates the gesture write for identification marking；
The gesture recognition module is connected with movement locus induction module, and the hand for writing and terminating to write is started for identification marking
Gesture；In an embodiment of the present invention, it is that " starting to write " and " end is write " the two states respectively define gesture triggering thing
Part：The action of " holding the single finger of fist to stretch out " represents and starts to write, and the action of " release fist " represents that end is once write,
When the gesture recognition module recognizes both gestures, corresponding state will be entered into.The present embodiment definition this two
Plant gesture simple, efficient, be easy to user to grasp and use, but not limited to this two ways.
Movement locus induction module, the change of track and state for recognizing the motion of ring-type finger ring, including acceleration is passed
At least one of sensor, obliquity sensor, optoelectronic induction positioner, localization by ultrasonic induction installation, movement locus sensing mould
Block can recognize the horizontal stroke of ring-type finger ring（One）, it is perpendicular（Shu）, skim（Pie）, point（Dian）, right-falling stroke（Fu）, folding（ㄱ、∠）Whipping and above-mentioned action are appointed
Meaning combination, the change of the track and state of the motion of ring-type finger ring is mainly worn in user's finger by by ring-type finger ring, Ran Houtong
Cross to change and wear the finger motion locus and state of ring-type finger ring and realize, i.e., change the motion of ring-type finger ring by finger ring gesture
Track and the change of state, naturally it is also possible to ring-type finger ring is not worn on finger the track that directly changes the motion of ring-type finger ring and
State, the ring-type finger ring gesture after combination includes circle, any broken line and SPL, horizontal stroke（One）, it is perpendicular（Shu）, skim（Pie）, point
（Dian）, right-falling stroke（Fu）, folding（ㄱ、∠）Etc. type gesture and they by after Arbitrary Rotation formed new gesture；
