Description
Technical field
The utility model relates to teaching equipment technical field, specially a kind of smart pen group network system applied to teaching.
Background technique
With the rapid development of Internet of Things, more and more products based on wireless transmission enter in people's lives, intelligence
Pen is that wherein one of more successful product, smart pen only need a piece of paper, and notes can be passed to hand in real time by one-pen
In the mobile devices such as machine, pad, cooperates the app in mobile device, these characteristics can be possessed with archive backups, smart pen, undoubtedly
It can apply on teaching classroom, but since classroom needs more smart pens, Bluetooth transmission mode will be unable to realize number at present
According to docking, so link structure must change.
Utility model content
The problem of for background technique, the utility model provide a kind of smart pen networking system applied to teaching
System.
To achieve the above object, the utility model provides the following technical solutions: a kind of smart pen networking applied to teaching
System, comprising:
Several smart pens: handwriting is generated and writes data by the smart pen；
Hub equipment: the Hub equipment is logical equipped with several AP embedded with BLE Soc chip, the AP by USB interface
It crosses bluetooth and receives the writing data that the smart pen transmits, then send data to Hub equipment；
Terminal PC: the terminal PC accesses the Hub equipment by USB interface, for receiving the Hub equipment transmission
It writes data and carries out final display.
As the utility model a preferred technical solution, USB interface communication is measured USBHID agreement.
Compared with prior art, the utility model has the beneficial effects that can be by more smart pens by the utility model
Carry out data transmission with terminal PC and be applied in tutoring system, keep teaching environment more intelligent, reinforces in teaching process
Interaction improves efficiency of teaching and quality.
Detailed description of the invention
Fig. 1 is the utility model overall structure diagram；
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Embodiment:
Referring to Fig. 1, the utility model provides a kind of smart pen group network system applied to teaching, comprising:
Several smart pens: handwriting is generated and writes data by the smart pen；
Several Hub equipment: the Hub equipment passes through bluetooth equipped with several AP embedded with BLE Soc chip, the AP
The writing data that the smart pen transmits are received, Hub equipment is then sent data to；
Terminal PC: the terminal PC accesses the Hub equipment by USB interface, and USB interface communication is measured
USB HID protocol, for receiving the writing data of the Hub equipment transmission and carrying out final display.
In the specific use process, smart pen is distributed to the use of each student in classroom, and terminal PC is then for teacher
It uses, teacher can carry out testing with hall in classroom, and students are finished writing answer by smart pen, the function of every smart pen
It is acquisition trajectories information and is encoded into data packet, packet serial number, device id, trace information etc. are contained in data, and data passes through BLE
Soc chip Bluetooth transmission comes, and then carries out USB between AP and the Hub equipment embedded with BLE Soc chip and docks, again by data
It is transferred to Hub equipment, for Hub equipment by received data original sample by USB transmission to terminal PC, terminal PC passes through packet
Device id can navigate to smart pen, can restore notes information further according to trace information.
The AP embedded with BLE Soc chip in the utility model once at most can connect 5~7 smart pens, then will
Several AP are connected in Hub equipment as Master role, and smart pen is as Slave role's BLE Soc chip at interval of one section
Time carries out single pass, will initiate the connection and asks to the source device of broadcast packet when scanning is to the broadcast packet with special characteristic
It asks, connection will do it the update of Connecting quantity after completing, finally carry out to the Service of smart pen and Characteristic
Read, due to BLE Soc chip connecting pen be it is linear, that is, need one by one pen be sequentially connected, whole connection speed can
To be adjusted by adjusting BLE Soc chip scanning interval, BLE Soc chip will stop scanning after connection number reaches maximum.
The process of whole networking are as follows:
1, more smart pens start to broadcast；
2, the Hub equipment for being connected with several AP starts to scan, and initiates the connection when scanning is to the broadcast packet for having specific information
Request, pen will go off the air after smart pen connects upper BLE Soc chip；
3, continue to connect other pens in the same way after BLE Soc chip has connected one-pen, when one
BLE Soc chip will stop scanning after connecting completely；
4, process completes connection as described above for each BLE Soc chip and smart pen, forms entire smart pen religion
Learn group network system.
Based on above-mentioned, the utility model has advantages in that can be by more smart pens and end by the utility model
End PC carries out data transmission and is applied in tutoring system, keeps teaching environment more intelligent, reinforces the interaction in teaching process,
Improve efficiency of teaching and quality.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Made any modifications, equivalent replacements, and improvements etc., should be included in the utility model within the spirit and principle of utility model
Protection scope within.
