Technical field
This utility model belongs to radio frequency identification and wireless charging technical field, is specifically related to a kind of portable mobile wireless based on RFID charging computer identity recognizer.
Background technology
At present, notebook computer charging is main uses traditional wire charging modes, and connecting power frequency AC is that Notebook Battery is powered.This charging modes has a lot of deficiency, and the plug as frequently touched easily causes mechanical wear, and exposed charging connector easily causes electric shock accidents.
Wireless charging technology typically utilizes electromagnetic induction, microwave or electromagentic resonance, can charge for battery when battery separates with charge power supply, and mode of operation is simple and convenient.Wireless charging system mechanical loss is little, manual maintenance low cost, and the requirement to environment is low, has higher adaptability.
Electromagnetic induction power transmission is apart from comparatively short, and the extent of deviation of power transmission and reception has a strong impact on power transmission efficiency, so the flow of research being currently based on the wireless charging technology of electromagnetic induction is limited.During microwave power transmission, efficiency is too low, causes much electric power to become heat energy and is consumed in vain, so the range of wireless charging technology based on microwave is limited.The wireless charging technology that major part uses at present is wireless charging technology based on electromagentic resonance.
Wireless charging technology based on electromagentic resonance is on the basis of wireless charging device based on electromagnetic induction, installs a high-frequency drive power supply additional, uses the LC resonant circuit having both coil and capacitor.The numerical value of resonant frequency, can with power transmission with reception unit interval from change and change.To this end, resonant frequency can be adjusted by control circuit, make the circuit of two unit resonate, thus effectively transmit power supply.
RFID is a kind of REID, and accepter is by radio signal identification object and read-write data, and it is widely used in the fields such as industry manufacture, merchandise control, public transport management, safe identification.Its adaptive capacity to environment is relatively strong, low to operating environment requirements, and round-the-clock automatic identification quickly responds, and can penetrate non-metallic objectsit is not a metal object, anti-interference, anti-collision ability is stronger.
Utility model content
The purpose of this utility model is to provide a kind of portable portable mobile wireless based on RFID charging computer identity recognizer easy to operate, small and exquisite.
For reaching above-mentioned purpose, this utility model adopts the following technical scheme that:
A kind of portable mobile wireless based on RFID charging computer identity recognizer, including:
RFID, usb circuit, signal processing module and user prompt module, usb circuit, signal processing module, user prompt module are sequentially connected；
The supporting RFID reader that RFID is used for being arranged in wireless charging transmitting terminal launches signal；
Usb circuit is used for connecting computer battery by computer USB interface and being located at the wireless charging receiving terminal of computer, and the receiving coil realtime power information monitored by wireless charging receiving terminal sends to signal processing module；
User prompt module includes the display lamp of at least two different colours, points out different wireless charging states by different colours display lamp；
Signal processing module compares receiving coil realtime power information and preset value by comparison amplifier, and lights the display lamp of user prompt module different colours according to different comparative results.
Compared to the prior art, this utility model has the advantage that and beneficial effect:
(1) simple in construction, small volume and less weight, easy to operate, wide market.
(2) identification efficiency can be effectively improved, reduce human cost.
(3) use RFID technique to make this utility model evaluator have reliability and the environmental suitability of excellence, be applicable to different operating environment.
(4) user can look for optimal charge position according to the prompting of user prompt module, thus promote charge power, reduces the charging interval.

Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in detail.
This utility model evaluator is for being provided with the computer of wireless charging receiving terminal.Wireless charging system includes wireless charging receiving terminal and wireless charging transmitting terminal, and wireless charging transmitting terminal transmits electric energy to wireless charging receiving terminal.To the computer of wireless charging can be carried out, wireless charging receiving terminal need to be located at computer, and connect with computer battery；Meanwhile, wireless charging receiving terminal carries information detecting module, and information detecting module is used for real time monitoring wireless charging receiving end power receiving coil.During use, evaluator (3) being inserted computer USB interface, computer USB interface is the access interface of evaluator (3)；Wireless charging transmitting terminal (4) arranges RFID reader (5), and RFID reader (5) connects the controller of wireless charging transmitting terminal (4), sees Fig. 1.
See Fig. 2, this utility model evaluator includes RFID (6), usb circuit (7), signal processing module (8) and user prompt module (9), wherein, RFID (6) is used for launching signal to supporting RFID reader (5), and usb circuit (7), signal processing module (8), user prompt module (9) are sequentially connected.Usb circuit (7) connects computer battery and wireless charging receiving terminal (1) by computer USB interface, and the power receiving coil information monitored in real time by information detecting module sends to signal processing module (8).Signal processing module (8) compares power receiving coil and preset value by comparison amplifier, and according to the display lamp of result of the comparison control user prompt module (9), user prompt module (9) shows wireless charging state by display lamp.
Originally, in being embodied as, user prompt module (9) includes red led (10), green indicating lamp (11) and alarm module, sees Fig. 3.When power receiving coil is less than preset value, then it represents that being unsatisfactory for wireless charging condition, red led is bright, and alarm module starts, and now, user adjustable computer position is until meeting wireless charging condition simultaneously.If power receiving coil is not less than preset value, then it represents that meet wireless charging condition, then green indicating lamp is bright.
Of the present utility model concrete application process be provided below:
When the entrance of this utility model evaluator is provided with the region of wireless charging transmitting terminal, and RFID is by own electronic sequence transmission to RFID reader, RFID reader identification user identity.This utility model evaluator is inserted the computer USB interface being provided with wireless charging receiving terminal, can be that evaluator provides electric energy by computer USB interface.
If the E-serial that RFID is launched is by checking, start wireless charging transmitting terminal, wireless charging transmitting terminal transmits electric energy to the wireless charging receiving terminal being located at computer, simultaneously, information detecting module real time monitoring wireless charging receiving end power receiving coil information, reaches signal processing module by usb circuit by power receiving coil information.If the E-serial that RFID is launched is not verified, the most do not start wireless charging transmitting terminal.
Signal processing module controls the display lamp display wireless charging state of user prompt module according to the power receiving coil information received.Power receiving coil can reflect current wireless charged state, and power receiving coil value the biggest then wireless charging state is the most preferable.So signal processing module lights different colours display lamp in user prompt module according to the current power receiving coil value received.
