Abstract
A kind of passive keyboard of NFC, including the NFC chip being sequentially connected with, MCU single-chip microcomputer and keyboard, connects in described NFC chip and has NFC antenna.By then passing through near-field communication (NFC) know-why, the NFC label being made up of NFC chip and NFC antenna is utilized to power to keyboard and make NFC device quickly find and identify this keyboard, thus realize the use between passive keyboard and NFC device, thus do not worry keyboard electricity not enough and cannot use, passive keyboard uses the electricity in a small amount of NFC device in connecting every time, then avoid the need for for its charging or frequently changing battery to keyboard at set intervals so that the use of passive keyboard is more convenient and can improve service efficiency；Meanwhile, owing to NFC is short-distance wireless communication technology standard, for bluetooth, the passive keyboard of NFC is the cheapest, uses the most extensive, and passive keyboard also has frivolous advantage easily.
Description
Technical field
The present invention relates to a kind of information technoloy equipment.
Background technology
Bigger for the general bodily form of common keyboard on market, it has not been convenient to the deficiency carried, people have developed a kind of wireless
Keyboard.Current Wireless Keyboard is to realize by the way of bluetooth mostly, and this bluetooth keyboard needs battery to power just to make
With, cause the production cost of bluetooth keyboard to increase, and battery be once be finished, and cannot use, at this moment must be charged or
Change battery, cause the service efficiency reducing keyboard.
Along with popularizing of mobile phone, flat board and computer, it is more and more higher that the use of the smart machines such as mobile phone is experienced requirement by people,
Currently occur in that again NFC smart mobile phone etc..
It is known that keyboard for typewriting is still had pursuance by a lot of people, they like being typewrited by keyboard.For currently
The deficiency of bluetooth keyboard, if utilizing NFC device, to realize passive keyboard, this is how well, the purpose institute of this applicant just
?.
Summary of the invention
It is an object of the invention to be to overcome the deficiencies in the prior art, it is provided that a kind of use is more convenient and can improve use
The passive keyboard of NFC of efficiency, its production cost is lower, it is the most extensive to use.
In order to solve the technical problem of above-mentioned existence, the present invention uses following technical proposals:
A kind of passive keyboard of NFC, including the NFC chip being sequentially connected with, MCU single-chip microcomputer and keyboard, connects in described NFC chip
There is NFC antenna.
In the improvement project of keyboard passive to above-mentioned NFC, described MCU single-chip microcomputer is 2C8051F series, MSP430 system
Row or STM8L series.
Prior art is compared, and the invention has the beneficial effects as follows: by then passing through near-field communication (NFC) know-why, utilizes
The NFC label being made up of NFC chip and NFC antenna is powered to keyboard and makes NFC device quickly find and identify this keyboard,
Thus realize the use between passive keyboard and NFC device, and thus do not worry that keyboard electricity deficiency cannot use, passive
Keyboard uses the electricity in a small amount of NFC device in connecting every time, then avoids the need for charging for it at set intervals
Or frequently change battery to keyboard so that the use of passive keyboard is more convenient and can improve service efficiency；Meanwhile, due to
NFC is short-distance wireless communication technology standard, and for bluetooth, the passive keyboard of NFC is the cheapest, uses the most extensive,
And passive keyboard also has frivolous advantage easily.
The present invention is described in further detail with detailed description of the invention below in conjunction with the accompanying drawings:
[accompanying drawing explanation]
Fig. 1 is the principle schematic of the embodiment of the present invention.
[detailed description of the invention]
A kind of passive keyboard of NFC, as it is shown in figure 1, include NFC chip 1, MCU single-chip microcomputer 2 and the keyboard 3 being sequentially connected with, described
Connecting in NFC chip 1 and have NFC antenna 4, they are located in keyboard base, have no difference with current Wireless Keyboard in terms of appearance.
The present invention in use, i.e. needs to use passive keyboard to stroke content in the display screen display of NFC device (such as NFC mobile phone etc.)
Time, NFC device can first pass through NFC antenna 4, supplies to NFC chip 1 and the MCU single-chip microcomputer 2 and the keyboard 3 that are connected with NFC chip
Electricity, so, when beaing keyboard 3, MCU single-chip microcomputer 2 judges that keyboard is worth accordingly, revises NFC core by IIC interface
The corresponding data of sheet, last NFC mobile phone just can read the number of NFC chip amendment according to the signal that NFC antenna 4 launches
According to, thus in NFC device, show the content of the beaten keyboard of people.
From the aforegoing it can be seen that the present invention is to utilize near-field communication (NFC) technology to achieve the use without battery keyboard, its profit
Power to keyboard by the NFC label being made up of NFC chip and NFC antenna and make NFC device quickly find and identify this key
Dish, thus realize the use between passive keyboard and NFC device, passive keyboard uses in a small amount of NFC device in connecting every time
Electricity, then user does not worries that keyboard electricity is not enough and cannot use, and avoids the need at set intervals for it yet
Charging or frequent to keyboard replacing battery so that the use of passive keyboard is more convenient and can improve service efficiency；Meanwhile, by
Being short-distance wireless communication technology standard in NFC, for bluetooth, the passive keyboard of NFC is the cheapest, uses the widest
General；And passive keyboard also has frivolous advantage easily, the most convenient when out using keyboard, and use keyboard can be decreased
Extra cost.It can use the material of softness to make, and is convenient for carrying.
Described MCU single-chip microcomputer 2 can use 8 of low-power consumption, 16, the single-chip microcomputer of 32, such as C8051F series,
MSP430 series, STM8L series etc..
Although the present invention being described in detail with reference to above example, but by the disclosure, those skilled in the art are shown
And be clear to, in the case of the principle and scope of the present invention limited without departing from described claim, can be to this
Invention makes a variety of changes or revises.Therefore, the detailed description of disclosure embodiment is only used for explaining rather than for limiting this
Invention, but it is defined by the subject-matter of the claims the scope of protection.
Claims (2)
1. the passive keyboard of NFC, it is characterised in that include NFC chip, MCU single-chip microcomputer and the keyboard being sequentially connected with, described
Connect in NFC chip and have NFC antenna.
The passive keyboard of NFC the most according to claim 1, it is characterised in that described MCU single-chip microcomputer be 2C8051F series,
