The interactive smart tablet and the client include a Bluetooth module for Bluetooth communication. When the client is within the Bluetooth communication distance of the interactive smart tablet, the participant can check in by operating the client carried by the client.

Further, when the current participant needs to check in in the conference room, the current client sends a Bluetooth data packet, and when the interactive smart tablet receives the Bluetooth data packet sent by the current client, the Bluetooth data sent by the current client The packet is parsed, the identity information of the current client is obtained through parsing, and a connection is established with the current client, where the identity information includes a device identification code and a username. It should be pointed out that the asynchronous connectionless link is established between the interactive smart tablet and the client, and the corresponding connection channel is not occupied between them. Therefore, the interactive smart tablet can communicate with multiple clients through the connectionless transmission mode. Bluetooth communication between the terminals.

Among them, it should be pointed out that the interactive smart tablet and the client have corresponding software sets, and the software has the function of controlling the bluetooth module, and communicates with each other through Bluetooth. And the software can generate a corresponding device identification code according to the device information of the client. And the software requires the user to register and log in to determine the information of each user, the information at least including the user's username. In order to make the method steps of the present invention concise, they are described by an interactive smart tablet and a client. It can be understood that the operations of the interactive smart tablet and the client for transmitting and receiving data are completed by software.

After the interactive smart tablet receives the Bluetooth data packet sent by the client, the identity information of the client is recorded, where the identity information includes the device identification code and the corresponding user name. After the conference starts, the interactive smart tablet is separated by a preset time. The polling sends the data packet to the client. When the client receives the data packet sent by the interactive smart tablet, it sends a response data packet to the interactive smart tablet. When the interactive smart tablet receives the response data packet sent by the client, it determines The participant carrying the client is in the presence state. When the interactive smart tablet does not receive the response packet sent by the client, it is determined that the participant corresponding to the username is absent, wherein it is necessary to indicate that the Bluetooth communication exists. The limitation of the distance, so when the Bluetooth module communication coverage of the interactive smart tablet is the entire conference room, and when the participant leaves the conference room, the interactive communication between the smart tablet and the client is disconnected, and the interactive smart tablet cannot receive the client. Send a response packet, so by interacting with the smart tablet and guest Bluetooth module communication status between the end of the meeting may determine the status of each of the participants, without staff manually determine the status of each of the participants attending.

The embodiment of the present invention receives the Bluetooth data packet through the interactive smart tablet and parses the identity information of the client, and sends the data packet to the client. Since the Bluetooth communication has a limitation of the transmission distance, when the participant leaves the conference room, the interactive smart tablet is The Bluetooth communication connection with the client is disconnected, so the interactive smart tablet cannot receive the response data packet sent by the client, so the interactive smart tablet can determine the attendance status of the participant according to whether the response data packet sent by the client is received, and the solution is resolved. It is difficult to discriminate the inconvenience of the participants in the meeting.

Please refer to FIG. 2, which is a flowchart of a method for judging a state of a participant provided in a second embodiment of the present invention, wherein the method is applied to a participant status determination system, and a plurality of name information is stored in the participant status determination system and The plurality of name information one-to-one correspondence address, the method includes:

Step S111, real-time monitoring whether the Bluetooth broadcast packet sent by the client is received;

Wherein, when receiving the Bluetooth broadcast packet sent by the client, step S112 is performed;

The interactive smart tablet monitors in real time whether the Bluetooth broadcast packet sent by each client is received, and each client in the Bluetooth communication range of the interactive smart tablet is determined according to the Bluetooth broadcast packet. When the participant enters the conference room, the participant needs to open the carried Software on the client that controls the Bluetooth module to broadcast Bluetooth broadcast packets so that the interactive smart tablet determines the presence information of its clients.

Step S112, sending a request broadcast packet to the client, where the request broadcast packet includes whether to participate Current meeting information;

When the interactive smart tablet receives the Bluetooth broadcast packet sent by the client, a request broadcast packet is sent to the client at this time, and the request broadcast includes information about whether to participate in the current conference, and when the client receives the interactive smart tablet, When requesting a broadcast package, the participant determines whether or not to participate in the conference based on the information of the conference, and confirms the request broadcast packet when the participant determines that the current conference needs to be attended.

Step S113: Real-time monitoring whether a Bluetooth data packet corresponding to the request broadcast packet sent by the client is received is received;

When receiving the Bluetooth data packet sent by the client and confirming the request broadcast packet, step S114 is performed.

Step S114, parsing the received Bluetooth data packets sent by the plurality of clients to determine identity information of each of the clients;

Wherein, when the participant confirms the request broadcast packet, the client sends a Bluetooth data packet confirming the request broadcast packet to the interactive smart tablet, and the Bluetooth data packet includes the identity information of the client. When the interactive smart tablet receives the Bluetooth data packet sent by the client and confirms the request broadcast packet, the data packet is parsed to obtain the identity information of the client, where the identity information includes the device identification code and the user name.

Step S115, polling and transmitting the data packet to each of the clients, and determining, according to whether the response data packet sent by each client is received, the participation status of the participant corresponding to each identity information;

The step of polling the data packet to each of the clients includes:

Transmitting a target number of the data packets to each client corresponding to the identity information, where each of the data packets includes one of the identity information, and the target number is the number of the clients;

After the conference starts for a period of time, the interactive smart tablet no longer judges whether there are any participants attending the conference. At this time, the number of all clients that determine the presence and the device identifier corresponding to each client are obtained. Further, the interactive smart tablet sends the data packet to each client every preset time, and the method of sending the data packet is to send multiple data packets, where the destination address of each data packet is The address corresponding to the device identification code of a client. Therefore, multiple data packets sent by the interactive smart tablet include all destination addresses sent to the corresponding client. Among them, it should be pointed out that when Bluetooth communicates, the communication address includes the source address and the target address. When the client receives the data packet sent by the interactive smart tablet, it determines whether its target address corresponds to it, and if it corresponds, parses the data packet. The content, otherwise the packet is dropped, so each client receives a corresponding packet sent by the interactive smart tablet and discards other packets.

It should be noted that, in other embodiments of the present invention, the step of polling and transmitting the data packet to each of the clients may further send the data packet to a client corresponding to each of the identity information by polling. End, wherein the data packet includes all of the identity information. That is, the destination address of the polling data packet is an address corresponding to the device identification code of all clients, and each client receives the data packet, and when each client determines that the data packet includes an address corresponding to the device identification code thereof, It will be parsed.

The method for transmitting Bluetooth data between the interactive smart tablet and each client is an asynchronous connectionless transmission link (ACL link), and the transmission time slot is applied during data transmission, and the master device can simultaneously and multiple slaves. The device establishes an ACL link, which belongs to a point-to-many asymmetric connection. It is specified in the existing Bluetooth protocol. One clock cycle is 312.5 μs, and 2×312.5 μs=625 μs is a time slot. The clock rate is 3.2 kHz. The smart tablet and each client send and receive data packets in different time slots. Among them, in the Bluetooth transmission process, one party must be responsible for receiving data as the central device, and the other party is responsible for transmitting data as the peripheral device, which makes the direction of Bluetooth communication unchanged. In order to realize mutual communication between the client and the interactive smart tablet, the interactive smart tablet and the client need to intermittently switch the Bluetooth transceiver status, as shown in FIG. 5, for the Bluetooth transceiver between the interactive smart tablet and the client. The timing diagram, the interactive smart tablet sends the data packet to each client in the t3 time, and after receiving the data packet in the t3 time, detects whether the response data packet sent by each client is received within the preset time, that is, t4, wherein Because the interactive smart tablet and the client are point-to-many asymmetric connections, each client receives a response packet after receiving the data packet of the interactive smart tablet, so the interactive smart tablet needs more time and more Frequent monitoring to receive each client The response packet is sent, so the time t4 of receiving the data packet of the interactive smart tablet is greater than the time t3 of transmitting the data packet. As described above, each client monitors whether to receive the data packet sent by the interactive smart tablet in t2 time, and after receiving the data packet sent by the interactive smart tablet, responds to a response data packet within t1, because the client needs more frequent The data packet is sent, so the time t1 of sending the data packet in each client is greater than the time t2 of receiving the data packet, and the interactive smart tablet polls the Bluetooth data packet once every interval, and the interactive smart tablet receives each according to the received The response packet responded by the client determines the participant status information of the participant corresponding to each user name.
