For example, for a multifunctional intelligent writing pen with writing color switching function, pen point type switching function, stroke thickness switching function, writing/erasing mode switching function, and difference number switching function, when a user inputs a writing color switching signal, the intelligent writing pen modifies data of a data bit corresponding to the writing color, that is, a controller in the intelligent writing pen finds a register corresponding to the writing color according to the writing color switching signal input by the user and modifies attribute data in the register, and the principle of setting other attributes is the same, which is not described herein again.

in the embodiment of the present invention, the intelligent writing pen is further provided with a communication module for performing data communication with the node configuration device, wherein the communication module may have multiple options, such as a WIFI communication module, a bluetooth communication module, or a 2.4G wireless communication module.

It should be noted that, the attribute data packet is sent to the node configuration device by the intelligent writing pen, and may be directly sent to the node configuration device after the attribute data packet is generated by the intelligent writing pen, or may be waited for the intelligent writing pen to touch the intelligent tablet after the attribute data packet is generated by the intelligent writing pen, and then the intelligent writing pen is triggered by the touch action of the intelligent writing pen to send the attribute data packet to the node configuration device.

in the embodiment of the invention, the node configuration device integrates hardware and software, and the hardware is provided with a control module, a storage module, a wireless communication module and a USB interface module. The control module runs a software program and is used for realizing data processing; the storage unit is used for storing an executable software program; the wireless communication module is used for carrying out wireless data communication with the intelligent writing pen so as to receive the attribute data packet sent by the intelligent tablet; the USB interface module is used for carrying out USB data communication with the intelligent tablet to send the attribute data packet from the intelligent writing pen to the intelligent tablet. In software, the executable software programs include a wireless communication program and a USB communication program. Specifically, the node configuration device performs wireless data communication with the intelligent writing pen through the wireless communication module according to a specified protocol to receive the attribute data packet from the intelligent writing pen, establishes a communication link with the intelligent tablet through a pre-installed driver (such as a USB HID device driver) of the intelligent tablet, and then sends the received attribute data packet to the intelligent tablet.

it should be noted that, the attribute data packet of the intelligent writing pen is finally sent to the intelligent tablet, and in the embodiment of the present invention, the node configuration device is used as a data transmission medium between the intelligent writing pen and the intelligent tablet, so as to implement data forwarding.

It should be noted that, in the form of hardware, the node configuration apparatus may be an independent apparatus independent from the smart pen and the smart tablet, or may be integrated in the smart pen or the smart tablet.

In the embodiment of the invention, a writing part (such as a pen point) of an intelligent writing pen is contacted with a touch part (such as a touch outer screen) of an intelligent flat plate and moves on the touch part, the intelligent writing pen sends an attribute data packet to the intelligent flat plate through a node configuration device, the intelligent flat plate analyzes the attribute data packet after receiving the attribute data packet, and sets the output attribute of the intelligent writing pen according to the attribute data in the attribute data packet, meanwhile, in the touch process of the intelligent writing pen, the contact positions of the intelligent writing pen are detected, a plurality of contact positions are combined to obtain the touch track of the intelligent writing pen, and a track line with corresponding attribute is output according to the touch track; the mode of detecting the contact position of the intelligent writing pen by the intelligent tablet can be infrared induction detection, capacitance induction detection or electromagnetic induction detection and the like.

According to the intelligent writing method provided by the embodiment of the invention, the intelligent writing pen receives the switching signal, generates the attribute data packet according to the switching signal and sends the attribute data packet to the node configuration device; the node configuration device receives the attribute data packet sent by the intelligent writing pen and sends the attribute data packet to the intelligent tablet through the communication network; and the intelligent tablet outputs a corresponding track line according to the attribute data in the attribute data packet and the detected touch track of the intelligent writing pen. Therefore, the method and the device can realize quick and convenient output of the trace lines with different attributes, and effectively improve the writing efficiency and the user experience.

In a preferred embodiment, the step S12 is specifically:

In the embodiment, a writing part (such as a pen point) of the intelligent writing pen is provided with a trigger switch, when the trigger switch of the writing part of the intelligent writing pen is squeezed, the trigger switch is in a trigger state, and a trigger signal is generated according to a preset time interval so as to trigger the intelligent writing pen to send an attribute data packet to the node configuration device; for example, in the process that the intelligent writing pen contacts and moves on the touch portion of the intelligent tablet, the trigger switch maintains the trigger state all the time, and generates the trigger signal according to the preset time interval, so that the intelligent writing pen automatically sends the current attribute data packet to the node configuration device according to the preset time interval, and when the writing portion of the intelligent writing pen leaves the touch portion of the intelligent tablet, the trigger switch is turned to the off state, and the intelligent writing pen stops sending the current attribute data packet.

It should be noted that, in the technical scheme of sending attribute data to the intelligent tablet once by the intelligent writing pen, if the intelligent tablet is powered off midway during use, the attribute of the intelligent writing pen cannot be continuously identified after being powered on again, so that a correct trace line cannot be output, the intelligent writing pen needs to be manually controlled to retransmit the attribute data, and the attribute data can be recovered to be normal, so that the user experience is poor; and adopt and trigger the intelligent pen according to the extrusion state of the intelligent pen writing position and send the mode of attribute data package to the dull and stereotyped intelligence automatically according to the time interval of predetermineeing, as long as the intelligent pen writes on the dull and stereotyped intelligence, its writing position will be extruded and send real-time attribute data package to the dull and stereotyped intelligence according to the time interval of predetermineeing automatically, correspondingly, as long as the intelligent dull and stereotyped is electrified again just can receive the attribute data package, and output correct orbit lines, need not extra operation, and convenient operation has improved user experience.

In another preferred embodiment, the step S12 is specifically:

the intelligent writing pen sends the attribute data packet to the node configuration device, and the intelligent writing pen touches the intelligent tablet to form a touch track.

In this embodiment, the intelligent writing pen establishes a connection with the node configuration device at the beginning, and the intelligent writing pen sends the generated attribute data packet to the node configuration device, and in the using process, if the intelligent writing pen updates the attribute data packet (the user inputs the switching signal again, and the intelligent writing pen regenerates the attribute data packet according to the switching signal), the updated attribute data packet is sent to the node configuration device after each update is completed.

In the present embodiment, the attribute data packet is generated by the smart pen and then directly transmitted to the node configuration device, so that the action of the smart pen touching the smart tablet and the action of the smart pen transmitting the attribute data packet to the node configuration device have no trigger relationship.

In a preferred embodiment, the attribute data packet further includes a difference number;

the step S15 specifically includes:

The distinguishing number can be understood as that a user gives an identity to the intelligent writing pen according to actual needs so as to distinguish a plurality of intelligent writing pens. When a plurality of intelligent writing pens input handwriting on one intelligent panel, the intelligent panel can distinguish the plurality of intelligent writing pens one by one according to the received different distinguishing numbers as long as the distinguishing numbers of the intelligent writing pens are set to be different, and then the intelligent writing pens are in one-to-one correspondence with the input contents to record.

In this embodiment, a plurality of difference numbers may be preset in the smart pen, so that the same smart pen may be switched between the plurality of preset difference numbers.

In this embodiment, on the one hand, the intelligent tablet updates the display content of the intelligent tablet according to the detected touch track of the intelligent writing pen, in specific implementation, the intelligent writing pen touches the intelligent tablet, the intelligent tablet detects the contact position of the intelligent writing pen, and correspondingly displays the handwriting content input by the intelligent writing pen on the display module of the intelligent tablet according to the contact position so as to be viewed by a user.

In the embodiment of the present invention, on the other hand, the smart tablet updates data of the display content storage area corresponding to the distinct number according to the detected touch trajectory of the smart pen, in a specific implementation, the smart tablet receives and analyzes an attribute data packet from the smart pen, detects whether the distinct number in the attribute data packet has already been allocated to the display content storage area, if the distinct number has not already been allocated to the display content storage area, allocates a corresponding display content storage area to the distinct number, and then records corresponding data in a storage module of the smart tablet (that is, the display content storage area allocated to the smart pen) according to the touch trajectory of the smart pen; the intelligent tablet allocates a display content storage area for the distinguishing number, and can be understood as that the intelligent tablet allocates a display content storage area for the intelligent writing pen represented by the distinguishing number, for an intelligent writing pen, the data stored in the display content storage area corresponding to the intelligent writing pen is the data corresponding to the handwriting content input by the intelligent writing pen displayed on the intelligent tablet, for example, a black letter "a" is input by one intelligent writing pen at the upper left corner of the intelligent tablet, and the data stored by the intelligent writing pen in the display content storage area corresponding to the intelligent writing pen is the data (including the contact position data and the corresponding attribute data) corresponding to the black letter "a".

It should be noted that, when the smart tablet allocates the display content storage area to the distinct number, the display content storage area may be further subdivided according to the time of inputting handwriting. For example, the smart pen 01 is used by the user 1 at 2016, 8/month and 7, and used by the user 2 at 2016, 8/month and 8, in order to distinguish the handwriting contents input by the user 1 and the user 2, the smart tablet allocates one display content storage area for the smart pen 01 at 2016, 8/month and 7, and allocates another display content storage area for the smart pen 01 at 2016, 8/month and 8.

In the embodiment, the attribute data packet containing the distinguishing number is sent to the node configuration device through the intelligent writing pen, the node configuration device forwards the attribute data packet to the intelligent tablet, and the intelligent tablet can update the display content of the intelligent tablet and the data of the display content storage area corresponding to the distinguishing number according to the detected touch track of the intelligent writing pen. Therefore, when a plurality of intelligent writing pens input handwriting on one intelligent panel, each intelligent writing pen and the input content of the intelligent writing pen can be recorded in a one-to-one correspondence mode through the intelligent panel, the difficulty of arranging the activity records is further reduced, the later-stage arranging efficiency is improved, and a later-stage reader can clearly master information provided by different users in the activity process; and the distinguishing numbers can be switched at the intelligent writing pen end, so that if N intelligent writing pens are required to input handwriting simultaneously in the activity process, as long as N available intelligent writing pens are available on site, the distinguishing numbers of each intelligent writing pen can be set to be different according to the actual requirements of users, the N intelligent writing pens can be distinguished from one another by the intelligent panel in the input process, and the input contents of each intelligent writing pen are recorded in a one-to-one correspondence manner.

In a preferred embodiment, the attribute data packet further comprises a data packet type identifier;

the step S152 specifically includes:

It should be noted that the operation of touching the smart tablet by the smart pen may be a writing operation or an erasing operation, and therefore, for the above two cases, different updating methods are required to update the display content of the smart tablet and the data in the display content storage area corresponding to the distinguishing number.

In this embodiment, the attribute data packet sent by the intelligent writing pen further includes a data packet type identifier, and the intelligent tablet receives and analyzes the target number packet. When the attribute data packet is recognized as the writing type according to the data packet identification, the display content and the data in the display content storage area corresponding to the distinguishing number are updated according to the writing rule, and when the attribute data packet is recognized as the pen erasing type, the display content and the data in the display content storage area corresponding to the distinguishing number are updated according to the pen erasing rule. In the embodiment, through the data interaction of the intelligent writing pen and the intelligent tablet, the intelligent writing pen can have two functions of writing and erasing, so that in the handwriting input process, a special erasing tool does not need to be additionally equipped or software in the intelligent tablet is called to erase, writing and erasing can be conveniently and quickly realized, the user experience is improved, and the use cost of a user is reduced.

It should be noted that, when the attribute data packet is identified as the writing type, a corresponding trace line is displayed according to the attribute data in the attribute data packet and the detected touch trace of the intelligent writing pen, and data corresponding to the trace line is stored in the display content storage area, which means that when the attribute data packet is identified as the writing type, the intelligent tablet acquires new content according to the detected touch trace of the intelligent writing pen, and updates the display content and the data of the display content storage area corresponding to the distinguished number according to the new content.

It should be noted that, when the attribute data packet is identified as the pen erasing type, displaying a corresponding track line according to the attribute data in the attribute data packet and the detected touch track of the intelligent writing pen, that is, obtaining erasing content according to the detected touch track of the intelligent writing pen, and updating the display content according to the erasing content, specifically, the intelligent tablet displays handwriting content of a certain attribute (for example, handwriting content displaying a background color) according to the touch track of the intelligent writing pen, so as to cover the existing handwriting content that needs to be erased, that is, the content displayed by the intelligent tablet after being updated is the content left after being erased. In addition, deleting the data corresponding to the track line from the display content storage area means that the data of the display content storage area corresponding to the distinguishing number is updated according to the erasing content, specifically, the data corresponding to the existing handwriting content which needs to be erased is deleted from the corresponding display content storage area, so that the data stored in the display content storage area is the data corresponding to the content displayed by the intelligent tablet after updating. Specifically, data corresponding to existing handwriting content which needs to be erased are deleted from a corresponding display content storage area, specifically, data corresponding to touch track touch position data of a detected touch track are obtained, and then data corresponding to handwriting content which is the same as the touch track touch position data in the corresponding display content storage area are deleted.

It should be noted that, the intelligent tablet identifies the type of the attribute data packet according to the data packet type identifier, specifically, when it is detected that the data packet type identifier is a first preset value, it determines that the attribute data packet is a pen-erase type, that is, the current working mode of the intelligent writing pen is a pen-erase mode; and when the type identifier of the data packet is detected to be a second preset value, judging that the attribute data packet is a writing type, namely that the current working mode of the intelligent writing pen is a writing mode.

It should be noted that, when there are multiple intelligent writing pens inputting handwriting on one intelligent tablet, each intelligent writing pen sends its own attribute data packet to the intelligent tablet through the node configuration device, and accordingly, after the intelligent tablet receives multiple attribute data packets, each attribute data packet is analyzed, whether each distinct number is allocated with a corresponding display content storage area is detected, and if no distinct number is allocated with a display content storage area, a corresponding display content storage area is allocated for the distinct number. Then, in the touch process of the intelligent writing pens, the intelligent panel respectively detects the contact position of each intelligent writing pen, updates the handwriting content input by each intelligent writing pen displayed by the intelligent panel according to the contact position of each intelligent writing pen, and correspondingly updates the data in the display content storage area corresponding to the distinguishing number according to the contact position of each intelligent writing pen; wherein, the intelligent tablet can select infrared induction detection, capacitance induction detection or electromagnetic induction detection and the like to detect the contact position of the intelligent writing pen, in the process that the plurality of intelligent writing pens touch the intelligent panel, the intelligent panel can assist in distinguishing the handwriting contents respectively input by the plurality of intelligent writing pens according to the area where the current input handwriting of each intelligent writing pen is located, for example, when three intelligent writing pens input handwriting on the intelligent tablet, the distinguishing numbers of the three pens are respectively 01, 11 and 10, one smart tablet may be divided into a left area, a middle area, and a right area, and when the smart pen 01 is first dropped, the smart tablet records the distinguishing number of the pen and the touch point position of the pen, and if the first pen falling position of the smart pen 01 is in the left area, then, if the input handwriting of the contact point position in the left area is detected, the input handwriting is considered as the input handwriting of the intelligent writing pen 01; the processing methods for the intelligent writing pens 11 and 10 are similar and are not described in detail herein.

Correspondingly, the invention also provides an intelligent writing system which can realize all the processes of the intelligent writing method provided by the embodiment.
