Detailed Description
In the following description, for purposes of explanation and not limitation, specific details are set forth, such as particular system structures, techniques, etc. in order to provide a thorough understanding of the embodiments of the invention. It will be apparent, however, to one skilled in the art that the present invention may be practiced in other embodiments that depart from these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.
In order to explain the technical means of the present invention, the following description will be given by way of specific examples.
In one embodiment, as shown in fig. 1, fig. 1 is a flowchart illustrating a conference presentation method based on bluetooth mesh technology, and the process thereof is detailed as follows:
s101: and acquiring a first broadcast data packet sent by a previous node, wherein the first broadcast data packet comprises demonstration update information of a demonstration document, a data packet number and a first network segment number.
The embodiment provides a conference presentation system based on the Bluetooth mesh technology, wherein the conference is organized, led and purposeful meeting activities and can comprise an organized conference and a multimedia class. The system includes a presenter terminal and a plurality of participant terminals. The main flow of this embodiment is a participant terminal, which is any participant terminal in the bluetooth mesh network, and the previous node is a node that sends the first broadcast packet to the participant terminal, and the previous node may be another participant terminal or a presenter terminal.
In this embodiment, all the nodes present represent presenter terminals or participant terminals that have joined the bluetooth mesh network, where the presenter terminals that have joined the bluetooth mesh network are the master node.
The first broadcast data packet comprises demonstration updating information of a demonstration document, when the conference demonstration sharing starts, the main node takes the demonstration document and the first operation as demonstration updating information and sends the demonstration updating information to the participant terminals through the Bluetooth mesh network, and each participant terminal acquires display pictures of a demonstration participant terminal display screen of the main node in real time. When the presenter changes the presentation document at the presenter terminal in the following process, the main node only needs to package the changed content, generate a first broadcast data packet and send the first broadcast data packet to each participant terminal. Specifically, the alteration content includes page turning, marking, page zooming, the position of the document where the current page is located, and the like of the presentation document. Therefore, when the subsequent demonstration document is changed, the information synchronization of all terminals can be realized only by sending the change content by the demonstrator terminal, so that smaller resources can be occupied, the data transmission speed in the Bluetooth mesh network is improved, and the real-time synchronous display effect of the participant terminal is optimized.
The main node monitors whether demonstration updating information exists or not according to a preset period, the preset period can be 1s, 2s or 5s, if the demonstration updating information exists, the demonstration updating information, the data packet numbers and the first network segment number are packaged into a first broadcast data packet, the first broadcast data packet is sent to an adjacent node, the adjacent node sends the first broadcast data packet to the adjacent node of the adjacent node, and the like until the first broadcast data packet is sent to all participant terminals.
In this embodiment, the first network number is a TTL value.
S102: and comparing the data packet number with a local pre-stored number.
In this embodiment, the current participant terminal is used as the home node, the home node stores the packet number of the first broadcast packet obtained last time as the local pre-stored number, compares the packet number with the local pre-stored number, and discards the first broadcast packet if the packet number is consistent with the local pre-stored number.
S103: if the local pre-stored number is not consistent with the data packet number, the demonstration updating information is stored, and the local pre-stored number is updated to be the data packet number.
In this embodiment, if the local pre-stored number is inconsistent with the data packet, the security verification is performed on the first broadcast data packet, and the first broadcast data packet further includes verification information, where the verification information includes a security key and an address list. The security key is used for enabling the local end node to carry out security verification, the demonstration updating information can be obtained only after the verification is passed, and the data packet is discarded if the verification is not passed.
Further, the verification information also comprises an address list, and the initial address list sent by the main node comprises the addresses of all participant terminals added into the Bluetooth mesh network. When each participant terminal joins in the Bluetooth mesh network, the main node immediately stores the address of each participant terminal joining in the Bluetooth mesh network, and when other nodes move out of the Bluetooth mesh network, the main node deletes the address of the device moving out of the Bluetooth mesh network. Therefore, the master node always keeps the node address of the participant terminal currently joining the bluetooth mesh network. And when the address list in the first broadcast data packet is empty, setting the number of the first network segments to zero.
In this embodiment, after the first broadcast packet passes the verification, the demonstration update information of the first broadcast packet is stored, and the packet number of the first broadcast packet acquired this time is used to replace the local pre-stored number.
S104: and subtracting a preset threshold value from the first network segment quantity, and sending the updated first broadcast data packet to the adjacent node.
In this embodiment, before the master node sends the first broadcast packet, it needs to calculate the shortest transmission distance from the master node to each non-relay node in the bluetooth mesh network, select the maximum value in the shortest transmission distances, encapsulate the maximum value as the first network segment number into the first broadcast packet, and subtract the preset threshold from the first network segment number every time the master node passes through one node, until the first network segment number is zero, the data packet is not forwarded any more, the preset threshold in this embodiment is 1, and the TTL value is subtracted 1 every time the master node passes through one node.
In this embodiment, the neighboring node of the local node is a node whose RSSI (Received Signal Strength) value of the Signal sent to the local node is greater than a preset RSSI value.
The embodiment first obtains a first broadcast data packet sent by a previous node, wherein the first broadcast data packet comprises presentation update information of a presentation document, a data packet number and a first network segment number; then comparing the data packet number with a local pre-stored number; if the local pre-stored number is not consistent with the data packet number, storing the demonstration updating information, and updating the local pre-stored number to be the data packet number; and finally, subtracting a preset threshold value from the number of the first network segments, and sending the updated first broadcast data packet to the adjacent node. In this embodiment, all nodes added to the bluetooth mesh network can receive the first broadcast data packet sent by the master node (presenter terminal), so that the presenter terminal and the participant terminal can realize synchronous play of presentation operation of the presentation document, and all users can check the presentation operation of the presentation document by the presenter through the participant terminal, thereby solving the problem that the fixed screen presentation effect is not good when the number of participants is too many.
In an embodiment of the present invention, as shown in fig. 2, before S101, fig. 2 shows another implementation flow of a conference presentation method based on bluetooth mesh technology, and the process thereof is detailed as follows:
s201: receiving a starting configuration request sent by a previous node, and adding the starting configuration request into a Bluetooth mesh network; the node is a presenter terminal or a participant terminal which is added into the Bluetooth mesh network;
s202: and sending a starting configuration request to the adjacent equipment to be distributed with the network, wherein the starting configuration request is used for indicating the adjacent equipment to be distributed with the network to join the Bluetooth mesh network.
In this embodiment, a node represents a terminal device that has joined the bluetooth mesh network, the previous node is a node that sends a configuration start request to the local node, and the neighboring to-be-configured network device is a terminal device that sends a signal RSSI value greater than a preset RSSI value to the local node and does not join the bluetooth mesh network.
In an embodiment of the present invention, as shown in fig. 3, fig. 3 shows another implementation flow of a conference presentation method based on bluetooth mesh technology, and the process thereof is detailed as follows:
s301: monitoring the data acquisition time of the first broadcast data packet, and taking the data acquisition time of the first broadcast data packet as first data acquisition time;
s302: acquiring operation information input by a user on the demonstration document, and recording the data acquisition time of the operation information as second data acquisition time;
s303: and calculating a time difference value between the first data acquisition time and the second data acquisition time, and displaying the operation information input by the user and the demonstration updating information of the first broadcast data packet in a split screen mode when the time difference value is smaller than a preset time difference value.
In this embodiment, when the user views the presentation document at the participant terminal, if it is unclear that the user needs to perform the operation alone, the operation information input by the user and the presentation update information of the presenter may be displayed in a split screen manner.
Specifically, when the operation of the user is captured at the local node, and the difference between the data acquisition time of the operation and the data acquisition time of the latest broadcast data packet received by the local node is smaller than the preset time difference, it is indicated that the operation is the operation of the local node alone by the user in the process of acquiring the demonstration document by the presenter, and therefore, at this time, the local node displays the operation information of the user on the demonstration document in the first screen area of the local display screen, and displays the demonstration update information of the first broadcast data packet received by the participant terminal in the second screen area of the display screen. Thereby enabling the user to better understand the contents of the presentation document.
Furthermore, whether split-screen display is performed can be determined according to the operation information input by the user, and when the operation information input by the user is page turning, page display size changing and the like, namely the page position positioned by the user and the page position positioned by the presenter are not the same position, the operation information of the user and the presentation updating information of the presenter are displayed in a split-screen manner; and if the operation information input by the user is marked on the current page, namely the page position positioned by the user and the page positioned by the presenter are at the same position, displaying the operation information of the user and the presentation updating information of the presenter on one screen, and displaying the operation information and the presentation updating information on the current page of the presentation document.
Taking a specific scenario as an example, if the presenter turns the page of the presentation document and the user does not know the content of the previous page clearly, the user may turn the previous page back, and at this time, in order to enable the user to receive the content currently spoken by the presenter in time while watching the previous page, the screen of the participant terminal may be split. If the presenter presents a certain page of the presentation document, and the user marks at a certain position of the current page, the participant terminal directly displays the operation information of the user and the presentation updating information of the presenter on one screen at the moment.
Further, when the participant terminal (home node) monitors that the time difference between the first data acquisition time and the second data acquisition time is greater than the preset time difference, the display screen is adjusted to be one-screen display of the operation information of the user on the presentation document.
Further, when the home node monitors that the operation information of the presentation document input by the user is not acquired within a period of time after the first data acquisition time, the display screen of the home node is adjusted to display the presentation update information on one screen.
In an embodiment of the present invention, as shown in fig. 4, fig. 4 shows another implementation flow of a conference presentation method based on bluetooth mesh technology, and the process thereof is detailed as follows:
s401: acquiring a sharing request input by a user, wherein the sharing request comprises a node address of a main node, and the main node is a presenter terminal added into the Bluetooth mesh network;
s402: according to the node address of the main node, the sharing request is sent to the main node through the Bluetooth mesh network, and the sharing request is used for indicating the main node to return sharing authorization information;
s403: acquiring and displaying the sharing authorization information;
s404: acquiring sharing operation information of the presentation document input by the user according to the sharing authorization information; packaging the sharing operation information into a second broadcast data packet;
s405: and sending the second broadcast data packet to other nodes of the Bluetooth mesh network.
In one embodiment of the present invention, when a user has a question about the presentation content of a presenter, a sharing request may be initiated, the sharing request being for sending to the presenter terminal, so that the sharing request carries the node address of the presenter terminal. According to the node address, the sharing request can be sent to the presenter terminal through the Bluetooth mesh network, after the presenter looks up the sharing request through the presenter terminal, if the presenter terminal clicks authorization, the presenter terminal obtains and sends sharing authorization information to the home terminal node, the home terminal node authorizes the sharing authority of the user according to the sharing authorization information, the user selects the sharing authority, and the home terminal node can send the sharing operation information of the user to all other nodes of the Bluetooth mesh network.
Further, in order to optimize the viewing experience of each terminal, when the participant terminal performs information sharing, the operation information sent by the presenter terminal and the participant terminal may be displayed on one screen, for example, when a certain presentation document is marked, the display screen may display both the mark sent by the presenter terminal and the mark sent by the participant terminal.
In an embodiment of the present invention, the sharing request includes the number of the second network segments, and a specific implementation flow of S402 in fig. 4 includes:
and sending the sharing request to a next node, updating the next node to be a current node, wherein the sharing request is used for indicating the current node to detect whether a node address of the main node exists in an adjacent node address corresponding to the current node, and if the node address of the main node exists in the adjacent node address corresponding to the current node, setting the number of the second network segments in the sharing request to be 1, and sending the sharing request to the main node.
In this embodiment, the second network segment number is specifically a TTL value, and since the sharing request is only communication between the participant terminal sending the sharing request and the presenter terminal, and the information transmission manner in fig. 1 is adopted, there may be a situation where multiple participant terminals send information, and the sharing request is transmitted through multiple lines, which causes waste of resources, therefore, in this embodiment, after the sharing request is sent to the neighboring node of the local node, the neighboring node is used as the current node, and it is determined in the current node whether a master node exists in the neighboring node of the current node, if a master node exists in the neighboring node of the current node, the second network segment number is directly set to 1, and the sharing request is sent to the neighboring node of the current node. And if the adjacent node of the current node does not have the master node, subtracting 1 from the number of the second network segments, continuously sending the second network segments to the adjacent node of the current node, updating the adjacent node of the current node to the current node, and continuously judging whether the adjacent node of the current node has the master node or not until the master node is found. Therefore, when the adjacent node of the current node acquires the sharing request, the number of the second network segments is updated to 0, and all the adjacent nodes of the current node do not forward the information downwards any more. Therefore, the forwarding process of the information is reduced, the waste of resources is reduced, and the transmission efficiency of the information is improved.
It should be understood that, the sequence numbers of the steps in the foregoing embodiments do not imply an execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present invention.
