The control operation of the current intelligent conference large screen is controlled based on an intelligent pen which is uniquely connected with the intelligent conference large screen. Under this kind of mode one to one, in the meeting, the meeting personnel only alone can operate the big screen of wisdom meeting, and when alone was operating, remaining meeting personnel can't be simultaneously to the big screen operation of wisdom meeting, had influenced the mutual experience of meeting.
Although there is a multi-terminal control situation in the existing control of the lecture software in the lecture process, the application situation is the multi-terminal control of page turning of the electronic manuscript displayed in the lecture software, and the control device is used for translating the electronic manuscript displayed in the lecture software by triggering a page turning signal. Compared with a one-to-one mode interaction experience is improved in the process of practical application, but the action of page turning through a trigger signal can only be controlled, so that the action cannot respond to other operation actions, such as: gesture movements, mouse movements, etc., or failure to respond to other types of controls, such as: and (5) voice control. This still affects the conference interaction experience of the participants.
Therefore, how to use multiple control devices for cooperative control is an urgent problem to be solved in the field.
The embodiment of the invention provides a solution for realizing the cooperative operation of a plurality of control devices in an intelligent conference scene and other scenes requiring the cooperative control of a plurality of control devices. Within the context of this disclosure, at least a control management system and a plurality of control devices may be included, and a communication interface may also be included, where the control management system is configured to respond to operation requests sent by the plurality of control devices, and the control devices may collect voice, gesture signals or respond to key clicks, for example, the control devices may be smart pens for voice control, handwriting input and key page flipping functions. In addition, the control equipment can be directly connected with the intelligent conference large screen, and the generated control signaling is directly sent to the intelligent conference large screen; the control equipment can also be indirectly connected with the intelligent response large screen through the communication interface, and the generated control signaling is sent to the communication interface and then forwarded to the intelligent conference large screen through the communication interface.
Fig. 1 is a schematic flow chart of a control method provided by the present invention. As shown in fig. 1, an embodiment of the present invention provides a control method, where the method may be applied to a control management system in a cooperative control scenario, where the control management system may specifically manage permissions of each control device, execute a control signaling sent by the control device, and the like. The method comprises the following steps:
step 110, receiving a control signaling;
specifically, the control signaling is a signaling with a control intention, and specifically may be voice information, gesture information, or event information. The control device can collect voice information and gesture information, or respond to a click event of a key on the control device, generate a control signaling and send the control signaling. The control signaling may be directly sent to the control management system by the control device, or may be sent to the communication interface by the control device first, and then forwarded to the control management system by the communication interface, in this process, the communication interface may only undertake the task of signaling forwarding, or may pre-process the control signaling, and then forward the pre-processed control signaling to the control management system, which is not limited in this embodiment of the present invention.
Step 120, determining the control authority of the control device corresponding to the control signaling based on the preset control authorities of the plurality of control devices;
in consideration of the fact that in practical application, after a plurality of control devices are connected to the large screen of the intelligent conference at the same time, the connected control devices can simultaneously operate the large screen of the intelligent conference, and at the moment, the large screen of the intelligent conference simultaneously responds to the operations to cause conflict, so that the operation of the large screen of the intelligent conference is disordered, and the progress of the conference is influenced. Therefore, the embodiment of the invention carries out authority control based on the plurality of connected control devices so as to realize that the plurality of connected control devices operate the intelligent conference large screen based on the self authority.
Specifically, after receiving the control signaling in step 110, the control management system may search the control authority of the control device corresponding to the control signaling in the preset control authorities of the plurality of control devices, so as to obtain the control authority of the control device for use in step 130. Here, the control authority defines a controllable range of the corresponding control device, the control management system only needs to execute the control signaling under the control authority, and the control signaling exceeding the control authority should be ignored and not executed.
It should be noted that the control permissions of the multiple control devices may be manually set by a speaker of the conference after the multiple control devices are connected, may also be the control permissions of the multiple control devices connected and set by the conference last time, and may also be set by the speaker for each control device in the list on the basis of a control device list connected in history, which is not specifically limited in this embodiment of the present invention. The set control permissions of the multiple control devices may be stored in a cache of the control management system, or may be stored in a hard disk of the control management system, which is not limited in this embodiment of the present invention.
And step 130, processing the control signaling based on the control authority of the control device corresponding to the control signaling.
Specifically, after the control authority of the control device corresponding to the control signaling is obtained from step 120, the control management system processes the control signaling according to the control authority. It should be noted that, processing the control signaling according to the control authority includes determining whether the control device sending the control signaling has the control authority required by the control signaling, if the control device does not currently have the control authority of the control signaling, abandoning the control signaling, and if the control device currently has the control authority of the control signaling, parsing the control signaling, so as to obtain a specific operation on the smart conference large screen, and perform a corresponding operation on the smart conference large screen. Further, analyzing the control signaling may be understood as performing voice recognition and intention understanding on voice information, and determining a corresponding operation for the event information according to an operation path corresponding to the gesture information conversion, which is not limited in this embodiment of the present invention. When executing the corresponding operation, the corresponding operation may be executed immediately, or may be executed sequentially according to a sequence of receiving each control signaling, which is not limited in this embodiment of the present invention.
According to the control method provided by the embodiment of the invention, the control authority of the control equipment for sending the control signaling is obtained through the preset control authorities of the plurality of control equipment, and then the control signaling is executed according to the control authority, so that the plurality of control equipment under the scene of cooperative control can realize ordered control. Specifically under the intelligent conference scene, the participant can operate the big screen of wisdom conference simultaneously, has improved the interactive experience of conference, has reduced the meeting latency to and reduced the risk that the controlgear that leads to because of controlgear's transmission damaged, and through the control of authority, produced conflict when having avoided many controlgear simultaneous control, further improve the interactive experience of conference.
Based on the above embodiments, fig. 2 is a schematic flow chart of the method for setting the authority of the control device according to the present invention. As shown in fig. 2, the control authority of the plurality of control devices set in advance in step 120 is determined based on the following steps:
step 210, determining the priorities of a plurality of control devices;
and step 220, determining the control authority of the plurality of control devices based on the priorities of the plurality of control devices.
Consider that during a meeting, there may be situations where multiple control devices are controlling simultaneously, for example, when multiple control devices perform gesture input operations in parallel, the speaker needs to perform some operations, such as: page turning or a flying mouse and the like, the operation of the speaker needs to be preferentially operated, so that the conference flow is not interrupted. In view of the above situation, the embodiment of the present invention sets the control authority of the control device in a priority manner, so that the control devices under different priorities can correspond to different control authorities, thereby further ensuring the orderly progress of the conference and improving the interactive experience of the conference.
Specifically, after the connection of the plurality of control devices is completed, priority setting may be performed on each control device, and then the control authority corresponding to each control device is set according to the priority of each control device. It should be noted that the setting of the control authority corresponding to each control device according to the priority of each control device may be determined based on a mapping relationship between the priority and the control authority. The priority of the control device may be fixed after being preset, or may be changed according to user operation during the conference. The priority may be determined based on a predetermined configuration, may also be determined according to a connection order, or may be determined according to a request made by a control device code, which is not limited in this embodiment of the present invention.
Based on the foregoing embodiments, the embodiments of the present invention provide a preferred embodiment, and the priority of the control device is determined based on at least one of a connection order, a communication order, and a device code of the corresponding control device.
Specifically, the priority of the control device is set according to the connection order, where the control device connected first has the highest priority, and the control devices connected subsequently have the ordinary priority, or the connection number of the control devices according to a preset threshold value, and when the connection number is smaller than the preset threshold value, the control devices sequentially set the priorities from high to low according to the connection order, and when the connection number is greater than or equal to the preset threshold value, the lowest priority is set, for example, 4 priority is set in total, the preset threshold value connection number is set to 3, the first 3 accessed control devices are respectively assigned the highest 3 priorities, and all the later accessed control devices are assigned the lowest 4 th priority.
Setting the priority of the control equipment according to the communication sequence, wherein the control equipment currently communicating with the control management system has the highest priority, the rest control equipment which is connected with the control management system but is not subjected to information interaction sets the common priority, if the subsequent new control equipment interacts with the control management system, the priority of the new control equipment can be adjusted to be the highest priority, and the priority of the control equipment which finishes the interaction with the control management system is adjusted to be the common priority.
The priority of the control device is set according to the device code, and the control device can actively send the device code of the control device to the control management system and apply for the highest priority to the control management system. After receiving the device code, the control management system may determine whether to assign the highest priority to the control device corresponding to the device code according to a preset rule, or may display the received device code on a screen, and an operator may confirm whether to assign the highest priority to the control device corresponding to the device code. For example, it is preset that at most 3 control devices can be configured with the highest priority, and at present, a control device is configured with the highest priority, and at this time, if the control management system receives a device code sent by a control device, the control management system may configure the highest priority for the control device corresponding to the device code.
The priority configuration mode provided by the embodiment of the invention can realize flexible configuration of the priorities of the multiple control devices, thereby ensuring the flexibility of the collaboration scene.
Based on the above embodiment, step 130 includes:
if the priority of the control device corresponding to the control signaling is the first priority, executing the control signaling;
otherwise, judging whether the control signaling accords with the control authority of the control device corresponding to the control signaling, if so, placing the control signaling into the cache region, and executing the control signaling in the cache region.
Specifically, for the received control signaling, the priority of the control device corresponding to the control signaling may be determined from the priority settings of the respective control devices.
On the basis, whether the priority of the control device corresponding to the control signaling is the first priority can be judged, where the first priority can be the highest priority among the preset priorities, where "first" is used for distinguishing from other priorities, and the control signaling sent by the control device at the first priority needs to be executed immediately.
If the priority of the control device corresponding to the control signaling is the first priority, the operation corresponding to the control signaling can be directly executed, if the priority of the control device corresponding to the control signaling is not the first priority, whether the control signaling conforms to the control authority of the control device corresponding to the control signaling needs to be judged first, if so, the control signaling is put into a buffer area, and the control signaling in the buffer area is executed. And executing the control signaling in the buffer area in sequence according to the sequence of the signaling entering the buffer area. In the process of sequential execution, if a new control signaling belonging to the first priority is received, the execution of the control signaling in the cache is suspended until the execution of the control signaling of the first priority is completed, and then the sequential execution of the control signaling in the cache is continued.
According to the control method provided by the embodiment of the invention, the control signaling sent by the control equipment with the highest control authority can be timely executed and responded in real time by setting a differentiated execution mode for the control signaling under the first priority, so that the conference process can be smoothly promoted.
Based on any of the above embodiments, step 110 includes:
and receiving a control signaling forwarded by the communication interface, wherein the control signaling is sent to the communication interface by corresponding control equipment.
Considering that the control equipment is generally used for various intelligent conference large screens, the control equipment is similar to a wireless mouse, and thus the control equipment is not limited by the type of the intelligent conference large screen. Therefore, the embodiments of the present invention use communication interfaces, such as: USB Dongle.
Specifically, the communication interface may be connected with the control management system through a physical interface, and the communication interface may be wirelessly connected with each control device. The control device may send the control information to the communication interface, which forwards the control information to the control management system. It should be noted that, in the embodiment of the present invention, connection with a plurality of control devices can be completed only by one communication interface, and the unique code of each control device in the communication interface corresponds to each control device. After receiving the control signaling, the communication interface may also pre-process the control signaling, and then forward the pre-processed control signaling to the control management system for use in step 120. It should be noted that, here, the preprocessing for the control signaling may be speech synthesis, adding a timestamp, or adding identification information of a control device corresponding to the control signaling, and the like, and the embodiment of the present invention is not limited thereto.
Fig. 3 is a second schematic flow chart of the control method provided by the present invention. As shown in fig. 3, an embodiment of the present invention provides a control method, where the method may be applied to a communication interface in a cooperative control scenario, where the communication interface may implement communication connection between a control management system and each control device, and the method includes:
step 310, receiving a control signaling sent by a control device;
specifically, the control signaling is a signaling with a control intention, and specifically may be voice information, gesture information, or event information. The control device can collect voice information and gesture information, or respond to a click event of a key on the control device, generate a control signaling and send the control signaling. The number of control devices may be one or more.
And step 320, forwarding the control signaling to the control management system, so that the control management system determines the control authority of the control device corresponding to the control signaling based on the preset control authorities of the plurality of control devices, and processes the control signaling based on the control authority of the control device corresponding to the control signaling.
Specifically, the control signaling received in step 310 is forwarded to the control management system, so that the control management system obtains the authority of the control device corresponding to the control signaling according to the control authorities of the plurality of control devices preset in the system, and processes the control signaling according to the control authorities. It should be noted that, forwarding the control signaling to the control management system may be directly forwarded without being preprocessed by the communication interface, or the control signaling after being preprocessed may be obtained and forwarded after being preprocessed by the communication interface, which is not limited in this embodiment of the present invention. The control signaling preprocessing may be speech synthesis, adding a timestamp, or adding identification information of a control device corresponding to the control signaling, which is not limited in this embodiment of the present invention.
In addition, the method executed in the control management system has been described in the above step 110 to step 130, and is not described herein again.
According to the control method provided by the embodiment of the invention, the control authority of the control equipment for sending the control signaling is obtained through the preset control authority of the plurality of connected control equipment, then the control signaling is executed according to the control authority, so that the control signaling sent by the plurality of connected control equipment can be responded and processed, participants can simultaneously operate a smart conference large screen, the interactive experience of the conference is improved, the waiting time of the conference is reduced, the risk of damage to the control equipment caused by the transmission of the control equipment is reduced, the conflict generated when the plurality of control equipment are controlled simultaneously is avoided through the control of the authority, and the interactive experience of the conference is further improved.
Based on the foregoing embodiment, in step 320, when the control signaling is a voice signaling, forwarding the control signaling to the control management system includes:
synthesizing a voice signaling sent by a plurality of control devices into a voice signaling and forwarding the voice signaling to a control management system;
or forwarding the voice signaling sent by the plurality of control devices to the control management system according to the priority of the plurality of connected control devices from high to low.
In order to reduce the processing pressure of the control management system and improve the processing performance of the control management system, so that the control management system can respond to a plurality of operation signaling in sequence and quickly or even in real time when receiving the operation signaling, the embodiment of the invention preprocesses the control signaling in the communication interface, and then forwards the preprocessed control signaling to the control management system through the communication interface.
Meanwhile, considering that the control signaling can support multiple types, the embodiment of the invention judges the type of the control signaling and carries out corresponding processing according to the judgment of the type.
Specifically, when the type of the control signaling is voice signaling, for the case that multiple paths of voice signaling from multiple control devices are received in the same time period, in order to improve the forwarding efficiency, the communication interface may synthesize multiple paths of parallel voice signaling into one path of voice signaling and forward the voice signaling.
In addition, in order to ensure the quality of the voice signaling, for multiple paths of voice signaling from multiple control devices received in the same time period, the communication interface may forward the voice signaling to the control management system according to the priority of the control device corresponding to each voice signaling and in the order from high to low of the priority of the control device.
Further, in the embodiment of the present invention, a manner of preprocessing the voice signaling is to synthesize a single voice signaling for forwarding multiple voice signaling, or to forward the synthesized voice signaling according to a priority order, which may be default of the communication interface, or may be configured by an operator through the control management system and sent to the communication interface, and after receiving the configuration, the communication interface may write the configuration into the cache, which is not limited in this embodiment of the present invention.
It should be noted that, after receiving the voice signaling, the communication interface may further perform processing such as noise reduction, echo cancellation, power amplification, and the like on the voice signaling, which is not limited in this embodiment of the present invention.
In addition, for the case that the type of the control signaling is a non-voice type, the control signaling may also be forwarded to the control management system according to the order from high to low of the priority of the control device based on the priority of the control device corresponding to the control signaling, and may also be forwarded to the control management system in sequence according to the order of the timestamps based on the timestamps of the received control signaling.
Based on the above embodiments, fig. 4 is a flowchart illustrating a control signaling forwarding method provided in the present invention. As shown in fig. 4, forwarding the control signaling to the control signaling in step 320 includes:
step 321, constructing control data based on the device identifier of the control device corresponding to the control signaling, the timestamp of receiving the control signaling, and placing the control data in a forwarding queue;
and 322, sending the control data to the control management system one by one based on the sequence of the timestamps of the control data in the forwarding queue.
Consider some control operations that need to be performed synchronously, such as: through gesture collection of the control equipment, writing or commenting is carried out in the intelligent conference large screen, or the control equipment provides coding applications such as priority lifting, and aiming at the messages, the communication interface can execute forwarding according to the time sequence of receiving the control signaling. In order to facilitate the control management system to know the sending sequence of each control message while receiving the control signaling, in the embodiment of the present invention, the communication interface adds a timestamp to the control signaling before forwarding the control signaling.
In addition, it is considered that the control management system needs to know the control device corresponding to the transmission of such control signaling, so as to perform different operation processes according to the control device, for example: when a plurality of control devices write or annotate, the control management system needs to distinguish different colors according to different control devices, or when the control devices send coding applications such as priority promotion, the control management system needs to correspondingly configure the coding applications such as priority promotion for the control devices. Therefore, the embodiment of the present invention adds the device identifier of the control device to the control signaling before forwarding the control operation.
Specifically, after receiving the control signaling, the communication interface may construct the control signaling, the device identifier of the control device corresponding to the control signaling, and the timestamp for receiving the control signaling into control data of the control signaling, and place the control data into a forwarding queue in its own buffer. Subsequently, the communication interface may send the control data to the control management system one by one according to the time stamps of the control data in the forwarding queue and the sequence of the time stamps. It should be noted that, when the communication interface sends the control data to the control management system one by one according to the sequence of the timestamps, the polling of the queue may be performed through a separate polling process or thread to extract and forward the control data corresponding to the earliest timestamp, or the control data corresponding to the earliest timestamp may be extracted from the queue at intervals by a timer and forwarded, which is not limited in this embodiment of the present invention.
Based on any of the above embodiments, in step 320, forwarding the control signaling to the control management system, further includes:
and if the control signaling conforms to the control authority of the control device corresponding to the control signaling, forwarding the control signaling to the control management system.
Specifically, the communication interface may determine the control authority of the control device corresponding to the control signaling, and if the control device has the control authority of the control signaling, the control signaling is forwarded to the control management system, and if the control device does not have the control authority of the control signaling, the control signaling may be directly ignored, and the forwarding of the control signaling is not performed. The control authority of the control device may be obtained by the control management system actively sending to the communication interface, and may also be obtained by the communication interface performing a request query to the control management system after receiving the control signaling.
Based on any of the above embodiments, the present invention further provides a specific embodiment, and fig. 5 is a structural diagram of connection and identification between the smart pen and the smart conference large screen provided by the present invention, as shown in fig. 5, a plurality of smart pens are connected to the USB Dongle, the USB Dongle is connected to the smart conference large screen, and the management and operation data processing are performed on the smart pen between the USB Dongle and the smart conference large screen through the control management system. The specific implementation manner of the cooperative control system provided by the embodiment of the invention is as follows:
in the embodiment of the invention, the communication interface is a USB Dongle, and the control equipment is an intelligent pen.
Step 510, a plurality of intelligent pen device ID codes are stored in the USB Dongle, and the connection between the intelligent pen and the control management system and the intelligent conference large screen can be realized by pairing the USB Dongle and the plurality of intelligent pen ID codes. The establishment of the specific connection can be realized through steps 511 to 513:
step 511, setting the refresh period of the data received by the USB Dongle of the smart conference large screen to be 5ms, so as to receive the ID code requested by the smart pen.
And step 512, when the smart pen is started, a request is sent to the USB Dongle, the USB Dongle pairs the received ID code of the smart pen, when the received ID code of the smart pen is consistent with the equipment ID code stored in the Dongle, the connection is successful, and the smart pen which is successfully connected can operate the smart conference large screen.
Step 513, when the received ID code of the smart pen is not consistent with the ID code stored in Dongle, the pairing fails, and the smart pen cannot operate the large screen of the smart conference.
And step 520, after the intelligent pen is connected with the large screen of the intelligent conference, the priorities of the connected intelligent pens can be managed through the control management system on the large screen of the intelligent conference, and the intelligent pen is endowed with operation functions and authorities of different priorities to the large screen of the intelligent conference. The control management system provides a plurality of intelligent pen priority algorithm options, including: a connection sequence priority ordering method, a smart conference large-screen digital communication sequence ordering method, a smart pen coding signal application ordering method and an administrator ordering method.
The connection order priority ordering method is to set the first connected intelligent pen as the highest priority by default, namely the intelligent pen with the role of the administrator (similar to a conference host), and the other intelligent pens are used as the common priority.
The communication sequence ordering method sets the highest priority of the intelligent pen which is interacting with the large screen of the intelligent conference for the control management system, and the other intelligent pens dynamically set the priority according to the communication with the large screen of the intelligent conference.
The coding signal application sequencing method is that the intelligent pen can send codes to a large screen of the intelligent conference to apply for the highest priority.
In addition, the speaker has administrator authority, and can set the priority of the intelligent pen. The administrator may set other smart pens to the highest priority and may rank the smart pen priorities through the administration page.
And the control management system defaults to carry out priority sequencing on the intelligent pens according to a connection sequence priority sequencing method.
If a plurality of intelligent pens send messages to the large screen of the intelligent conference at the same time, the intelligent pen with the highest priority obtains the qualification of operating the large screen of the intelligent conference, and the rest control messages enter a message buffer area to wait for responses in sequence.
And step 530, realizing data interaction between the multiple intelligent pens and the intelligent conference large screen and the control management system thereof through voice interaction, gesture interaction, flying mouse interaction and key interaction.
For the voice interaction function, a DSP chip for voice processing is embedded in a USB Dongle, and when voice data of an intelligent pen exists, the DSP chip can be used for noise reduction, echo cancellation and power amplification processing; when there are multi-channel voice data of many pens, can carry out speech synthesis on the basis of single-channel speech processing, improve the communication efficiency of the participant, the concrete step is as follows:
and 531-1, if only one intelligent pen controls the large screen of the intelligent conference through voice, transmitting voice data to the USB Dongle, and controlling the large screen operation of the intelligent conference through noise reduction, echo elimination, power amplification and voice identification and voice control.
And 531-2, if a plurality of intelligent pens control the large screen of the intelligent conference through voice, if the large screen control software of the intelligent conference selects multi-path voice synthesis, the USB Dongle synthesizes multi-path voice after receiving multi-path voice data, and controls the large screen of the intelligent conference through voice.
When a plurality of intelligent pens control the large screen of the intelligent conference through voice, if the selection of the large screen control software of the intelligent conference does not form multi-path voice, the multi-path voice controls the large screen of the intelligent conference according to the priority of the intelligent pens in sequence. And the administrator can only allow one path of voice control, and other paths of voice control are invalid.
For the gesture function of controlling the channel interaction, the gestures of a plurality of pens can be input in parallel. The multiple intelligent pens can write or annotate simultaneously in scenes such as whiteboards and document browsing modes, handwriting colors of different intelligent pens are different, and the touched fingers are replaced by the intelligent pens for contactless remote input. The method comprises the following specific steps:
step 532-1, the smart pen performs gesture input, wherein the smart conference large screen can receive gesture input of a plurality of smart pens at the same time, so as to write and annotate on the smart conference large screen at the same time.
In step 532-2, after receiving the control data of different intelligent pens, the USB Dongle can distinguish from other intelligent pens according to the ID code of the intelligent pen. The USB Dongle sets a timestamp according to the initial time of receiving the intelligent control data, and then adds the timestamp to a processing queue of the control data.
And 532-3, the USB Dongle sending end continuously acquires the control data from the processing queue and sends the control data to the control management system according to the time stamp sequence.
And 532-4, after the control management system receives the control data of the plurality of intelligent pens, the control data of the plurality of intelligent pens can be fused on a large screen of the intelligent conference according to the time sequence. On a large screen of the intelligent conference, by taking remarking as an example, different intelligent pens can be used for differently remarking handwriting with different colors according to ID codes of the intelligent pens. Based on the processing efficiency (ms level) of the intelligent pen, the USB Dongle and the control management system, the annotation data completed at the same time can be seamlessly merged together.
For the flying mouse function in command channel interaction, the intelligent pen with the highest priority can use the flying mouse to control the intelligent conference large screen. The method comprises the following specific steps:
step 533-1, the smart pen responds to the vole keystroke event and sends the vole control command.
And step 533-2, the USB Dongle only transmits the control data produced by the intelligent pen with the highest priority to the control management system through the HID technology to simulate the intelligent pen into a mouse.
The command channel is independently controlled and independent of the voice channel and the control channel, so that mutual interference can be avoided under the condition that a plurality of pens work in coordination.
For the key function in the command channel interaction, the intelligent pen can send keys to the intelligent conference large screen, and different control commands corresponding to different keys are achieved. The method comprises the following specific steps:
step 534-1, the smart pen sends the code. Wherein the encoding comprises: the method applies for the highest priority or other special and quick operations on the large screen of the intelligent conference, including but not limited to applying for connection, actively disconnecting, switching colors and the like, and different operations correspond to different codes. This operation is distinguished through wisdom pen ID code, only plays the wisdom pen of oneself using, does not influence the operation of other wisdom pens.
In step 534-2, the USB Dongle stores the available digital signals of the smart pen in the software chain table, and the operation is linearly executed according to the priority of the pen and the request time sequence.
