In order to make the technical solutions better understood by those skilled in the art, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings.
As shown in fig. 1, a flowchart of an embodiment of an intercom networking method according to the present application. The intercom networking method comprises the following steps:
step S100: continuously transmitting time frames to network nodes in a transmission range so as to publish network topology and corresponding voice time slots of each network node in the time frames through beacon time slots of the time frames, wherein the time frames comprise time division multiplexing beacon time slots, voice time slots and contention time slots;
step S200: receiving a time frame sent by the newly added network node to acquire a network access request of the newly added network node through a competition time slot;
step S300: and allocating the voice time slot in the time frame to the newly added network node, and updating the network topology.
Specifically, one of the interphones is taken as a main coordinator, time frames are continuously transmitted outwards, topological information of the network is diffused outwards through beacons in the time frames, and voice time slots distributed to the interphones serving as network nodes are distributed in the time frames in time division multiplexing, so that the existing network nodes in the network can determine the latest network topology and the own voice time slots in real time.
And acquiring a network access request sent by a new network node through a competition time slot in the time frame, and carrying out network access application in a time period independent of the voice transceiving of the interphone and the sending of the beacon in the network.
And updating the topological structure according to the network access application of the new network node and allocating time slots in the time frame for the new network node to carry out communication. The scheme can automatically construct an interphone communication network based on time division multiplexing, and at least two groups of interphones in the network can talk simultaneously in the same time period in a time division multiplexing mode, so that the effect of full-duplex conversation is achieved. The scheme improves the communication efficiency of a group of interphones.
Preferably, before step S100, after the intercom is turned on, an intercom first scans whether a multi-hop network already created exists nearby, and if so, directly applies for joining the network as a network node. If not, the interphone is used as a master coordinator to create a new multi-hop talkback network. The network nodes in the network topology and the allocation of the voice frames in the time frames are added according to the continuous application of the newly added network nodes.
Further, the time frame further includes a control timeslot, the control timeslot corresponds to the network node through allocation, and the method further includes:
step S400: and controlling the network nodes to externally transmit time frames so as to forward the network topology sent by the main coordinator and the corresponding control time slots and voice time slots of each network node in the time frames through the control time slots.
The full-duplex communication of the intercom network related in this embodiment is realized by a time frame form of transceiving time division multiplexing, and one time frame is the smallest communication unit in the communication mode. Specifically, the time frame is divided into a beacon time slot, a control time slot, a voice time slot and a competition time slot, each time slot corresponds to a signal in a period of time in one time frame, and therefore, corresponding information is transmitted according to the function of the time slot, so that each network node in the network can share a link in the time length of one time frame.
Specifically, one time frame includes 1 beacon slot Ts, and is used by the master coordinator to transmit beacons and control data. A number of control slots Tc are used by the network node for relaying control data. A number of voice slots Ta used by the network node for transmitting voice data. And one competition time slot Tr is used by the network nodes in competition and used for requesting signaling transmission of network access requests, roaming requests, speaking right applications and the like. The time frame period is based on the processing period of the voice processing module.
The beacon time slot and the control time slot are used as downlink signaling, and comprise network topology data and time slot allocation data which are sent by a main coordinator, and the control data are broadcasted to the whole network by utilizing the beacon time slot and the control time slot. And after receiving the control signaling of the father node, the network node forwards the control signaling through the corresponding control time slot. After the master coordinator and the network nodes finish sending the control data, all the network nodes in the network acquire the latest network control data and perform clock frequency synchronization. In the intercom network described in this embodiment, any network node may be used as a parent node of other network nodes, and leaf nodes of other network nodes and the master coordinator according to the network topology.
The contention time slot is used as an uplink signaling and is sent to a parent node of the network node through the network node, wherein the contention time slot comprises network access application, roaming, speaking right application and the like. The report can be transmitted step by step, the father node can perform signaling feedback in the control time slot of the next time frame period, and the father node transmits to the superior father node by adopting the competition time slot.
The DSP processes the voice speed to limit the number of people speaking at the same time, and the conversation among all network nodes can be ensured not to be influenced by each other through competing the speaking right in time slots.
The network nodes need to synchronize to a time frame period based on the main coordinator, and the synchronization method is to perform synchronization calibration by using control signaling sent by the parent node mounted by the network nodes. If the father node of the network node is the main coordinator, and the main coordinator is positioned at the starting point of the time frame period when sending the control data, the adjacent network node can calculate the starting point of the time frame period of the main coordinator according to the communication delay, so that the local time frame period timer is calibrated to realize the synchronization with the network. The network nodes connected with the master coordinator through other network nodes cannot rely on the control signaling of the master coordinator to perform time frame synchronization, and the network nodes can only rely on the father nodes of the network nodes to perform time frame synchronization. According to the time slot interval between the control time frame and the beacon of the father node and the communication time delay, namely the calibration value from the time frame period starting point of the main coordinator, the local timer is adjusted according to the calibration value, and the time frame period synchronization of the main coordinator can be realized locally.
When the interphone in the network generates the requirement of receiving and sending voice, the dynamic application and dynamic release mechanism of the speaking right is realized through voice activity detection, so that the full-duplex talkback function of multiple persons is realized. Specific voice activity is generated by detecting the voice of the microphone, initiating a speaking right application when the user starts speaking, and releasing the speaking right when the user does not speak. Because the voice detection speed is very fast, the networking user can realize full-duplex talkback without manual intervention.
By setting the control time slot and forwarding the signaling sent by the coordinator through the control time slot, the interphone network can be extended to a multi-hop network, and the communication coverage range which is longer than the communication distance of two interphones can be realized through a multi-hop technology.
In a multi-hop intercom system network, any network node at any time may become a relay forwarding node, or a leaf node. Wherein the relay forwarding node helps to forward control data and voice data, and wherein the leaf nodes only transmit their own data and receive data of other nodes. The switching of the network node between the transit node and the leaf node is transparent to the user. The scheme can greatly expand the use range of the interphone network by forming a multi-hop network.
Further, referring to fig. 2, the step S200 specifically includes:
step S201: the control network node receives a time frame sent by the newly added network node and acquires a network access request of the newly added network node through a competition time slot;
step S202: controlling the network node to send a time frame so as to send a network access request of a newly added network node to a parent node of the network node through a competition time slot according to a network topology until the network access request is transmitted to a master coordinator;
step S203: and controlling the network node to receive acceptance feedback through the control time slot corresponding to the parent node in the subsequent time frame, and sending acceptance feedback to the leaf node or the newly added network node through the control time slot corresponding to the network node in the subsequent time frame.
Specifically, the newly added network node detects the interphone network, in the process of accessing the network, a time frame is sent out in a broadcasting mode, an access request is sent out through a competition time slot, the network node which sends the time frame by the newly added network node is received as a parent node of the newly added network node, the parent node sends out the time frame, the access request of the newly added network node is forwarded through the competition time slot, the access request of the newly added network node is forwarded to a main coordinator according to network topology, the main coordinator sends an acceptance feedback through a beacon time slot, the network node forwards the acceptance feedback to a child node through a control time slot until the acceptance feedback is forwarded to the newly added network node through the control time slot by the parent node of the newly added network node, the newly added network node determines to access the network, and when the newly added network node does not receive the acceptance feedback, after a certain time interval, the network access request is proposed again, the scheme is favorable for orderly processing the network access request of the newly added network node, and the network access efficiency and the success rate of the newly added network node are improved.
Further, the method further comprises:
step S501: controlling the network node to receive the time frame so as to receive roaming requests sent by other network nodes through contention time slots;
step S502: controlling the network node to send out a time frame so as to send out the roaming request to a parent node of the network node through a competition time slot according to a network topology until the roaming request is transmitted to a main coordinator;
step S503: and the master coordinator adjusts the network topology according to the roaming request.
Specifically, a roaming request is provided through a competition time slot, the main controller is controlled to adjust the network topology, and the network topology is updated.
In order to solve the above technical problem, an embodiment of the present application provides an intercom communication method, which adopts the following technical scheme:
referring to fig. 3, an intercom communication method, the method comprising:
step Sa: receiving a time frame sent by a network node to acquire a speaking right request of the network node through a competition time slot;
and Sb: determining a group of network nodes corresponding to the speaking right request according to the topology of the interphone network;
step Sc: allowing the request for speaking right according to the set of network nodes being serviceable;
step Sd: sending out a time frame to reply to the speaking right request through a beacon time slot;
step Se: the time frames are sequentially transceived by the set of network nodes to transmit voice through the voice time slot.
When a network node applies for and releases the speaking right in the talkback process, the node sends a signaling to a main coordinator through a competition time slot. If the signaling can not directly reach the master coordinator, forwarding requests can be carried out in competition time slots through a plurality of network nodes serving as transit nodes. The resulting responses to these request signals are fed back through the control data in both beacon slots and data slots. The adoption of CSMA/CD (carrier sense multiple access/collision detection protocol) algorithm for contention slots supports all nodes other than the master coordinator to use the slots.
Referring to fig. 6 and 7, when a plurality of nodes apply for a speaking right conflict. After the interphone 5 sends the signaling in the contention time slot, it receives the signaling receiving feedback in the control data sent by the parent node interphone 3 in the next time frame period, and judges whether the signaling is received and forwarded by the parent node interphone 3. If no feedback is obtained, the application signaling is sent after waiting for several time frame periods at random. If the uplink signaling sent by each contention slot is successfully received by the parent node, the parent node of the uplink signaling carries out response feedback in the control data in the next time frame period. The network entry signaling and the roaming signaling are also signaled according to the feedback mechanism by using contention time slots.
The communication between the network node and the network node is realized in a broadcasting mode, when the network node receives a broadcasted time frame and determines that the time frame needs to be forwarded by the network node through a control time slot, the content of a voice time slot in the received time frame is further encapsulated into the time frame of the network node in the broadcasting mode and is broadcasted until the time frame is further processed, and the method further comprises the following steps:
step Sf: receiving a time frame sent by a network node to acquire a release request of the network node through a competition time slot;
step Sg: and restoring the corresponding network node to be in a serviceable state according to the release request.
When the requirement of network nodes cannot be met constantly due to the influences of the inter-interphone switch, the distance between the inter-interphones and the interference on the inter-interphone signals in the network, and the network topology after the establishment, the requirement that the network topology may change in the process, referring to fig. 5 and 6, when the inter-interphone 5 detects that the signal quality of the inter-interphone 3 is poor and the signal quality of the inter-interphone 4 is better, the inter-interphone 4 is determined to roam. The interphone 5 firstly initiates a roaming application to the interphone 4 in the competition time slot, and the interphone 4 receives the request and then forwards the roaming application signaling to the upper-level transfer node until the application signaling reaches the master coordinator interphone 1. After the intercom 1 decides to agree with the roaming application, the networking topology and the time slot allocation condition are updated, and new control data are broadcasted through the beacon time slot when the next time frame starts. The interphone 4 receives the new control data and becomes a transit node. And the interphone 5 receives the new networking data and determines the own upper-level transfer node as the interphone 4.
Further, since the transit node may fixedly occupy the control timeslot and the voice timeslot to perform relay forwarding of data and voice, the main coordinator needs to perform reasonable allocation according to the limited condition of the bandwidth resource, and the hop count and scale of the network may also receive the constraint of the condition. Especially, the allocation of voice time slots will occupy the number of leaf nodes that can speak simultaneously when the number of transit nodes is too large. Therefore, the master coordinator controls the number of transit nodes according to the limited condition of the bandwidth.
It will be understood by those skilled in the art that all or part of the processes of the methods of the embodiments described above can be implemented by a computer program, which can be stored in a computer-readable storage medium, and can include the processes of the embodiments of the methods described above when the computer program is executed.
