In the embodiment of this application, for multiple electronic devices that have a trust relationship within the short-distance communication range, one electronic device will maintain a logical connection with other electronic devices, and the status and information of these electronic devices can be synchronized when the system is running . These mutually trusted electronic devices can form a smart connection network.

It should be noted that the Zhilian network is only a name of the network involved in the embodiment of the present application, and the network involved in the embodiment of the present application may also have other names, which are not limited.

Multiple electronic devices in the Smart Connect network support local short-distance communication methods, such as Bluetooth, Wi-Fi or near field communication (near field communication, NFC) and other short-distance wireless communication methods, or support for universal serial bus (universal serial bus, USB) and other short-distance wired communication methods.

The Wi-Fi communication mode is supported between the mobile phone and the smart speaker (speaker for short).

After the Smart Connect network is completed, the electronic devices in the Smart Connect network go online. Specifically, multiple electronic devices may exchange information (including identity information of the electronic devices, etc.) with each other during or after mutual discovery, so as to notify each other of the identities of the online electronic devices. Then, the electronic devices in the Zhilian network can perform online detection through the heartbeat packet, so as to know the status of each online electronic device. In the embodiments of the present application, being online means that the electronic device can be detected through a heartbeat packet, and does not necessarily mean that a network connection or data channel has been established.

For example, after the electronic device 1 in the Smart Connect network sends a heartbeat packet to the electronic device 2, if it receives a heartbeat response message sent by the electronic device 2 within a preset time period, the electronic device 2 is considered to be online. Online electronic devices in the Zhilian network can initiate business data transmission at any time, so that business processing can be completed quickly, directly and collaboratively. If the electronic device 1 does not receive the heartbeat response message sent by the electronic device 2 within the preset time period, the electronic device 2 is considered to be offline. The electronic devices in the Zhilian network can also notify each other of the identity information of offline devices, so that each electronic device can know the current situation of online devices and offline devices.

The receiving timing enables the electronic device at the receiving end to receive the heartbeat packet when it is in the window receiving state, thereby improving the receiving efficiency of the heartbeat packet, reducing the number and duration of sending and receiving the heartbeat packet, and reducing the power consumption of the electronic device. Multiple electronic devices in the system realize fast, timely and accurate online detection.

The online detection method based on the heartbeat packet provided by the embodiment of the present application will be described below with reference to the accompanying drawings.

The electronic devices in the Zhilian network can also be called nodes. In the embodiment of the present application, there is a superior-subordinate relationship between the nodes of the Smart Connect network, and the superior node can send a heartbeat packet to the subordinate node to detect whether the subordinate node is online. Wherein, the upper-lower relationship between nodes may be determined according to the information of the nodes themselves, and/or the mutual relationship between the nodes and other factors. In the Zhilian network, a node can have one or more subordinate nodes.

For example, the information of the node itself may include one or more of network capability information, processing capability information, network quality, power information, movement information, service information, and service set identifier (service set identifier, SSID). Wherein, the network capability information may include the network connection supported by the node, the maximum bandwidth supported by the network connection supported by the node, the connection information of the network connection supported by the node (such as port number, media access control address (media access control, MAC) address or At least one of Internet protocol (internet protocol, IP) address). The processing capability information of the node represents the processing capability of the node, and includes, for example, power consumption of the node, chip processing capability, and memory.

For example, the interrelationships between nodes may include content such as network topology relations. The network topology relationship includes the network connection modes supported by each node, and the communication path between nodes.

Exemplarily, the upper-lower relationship between nodes may be determined according to the weight of the nodes and the network topology relationship between the nodes. Among them, the weight of the node can be determined by the node itself according to the network capability information of the node and the processing capability information of the node, for example, the weight of a node with high power consumption, insensitivity to power consumption, good chip processing capability, large memory and strong network capability High; on the contrary, nodes with low power consumption, sensitivity to power consumption, poor chip processing capabilities, small memory and weak network capabilities have low weights.

In the embodiment of the present application, the nodes in the Zhilian network may include a central node, a first-level node, and a second-level node, etc. according to the relationship from the upper level to the lower level. Among them, the central node is the highest-level node, only the lower-level nodes, no upper-level nodes. The lower-level nodes of the central node are called first-level nodes, and the central node is the upper-level node of the first-level node; the lower-level nodes of the first-level node are called second-level nodes, and the first-level node is the upper-level node of the second-level node; The network may also include tertiary nodes or quaternary nodes, etc. The embodiment of the present application does not limit the number of layers of nodes included in the Smart Connect network. A Zhilian network usually includes a central node, and may have one or more subordinate nodes belonging to different levels. In addition, if a node has both upper-level nodes and lower-level nodes, the node can also be called an intermediate node. If a node has only upper-level nodes and no lower-level nodes, the node can also be called a tail node.

For example, in the Smart Connect network shown in FIG. 1A , the connection between the large screen and the mobile phone, and between the large screen and the watch support the Bluetooth BLE network connection. The Bluetooth BLE network connection is supported between the mobile phone and the headset, and the Wi-Fi network connection is supported between the mobile phone and the speaker. According to factors such as weight and network topology among electronic devices, the central node is determined as the large screen, the large screen is the upper node of mobile phones and watches, and the mobile phone is the upper node of earphones and speakers. Correspondingly, mobile phones and watches are subordinate nodes of large screens, and earphones and speakers are subordinate nodes of mobile phones.

In the smart connected network shown in Figure 1A, according to the network topology, the network connection is supported between the mobile phone and the earphone, and between the watch and the earphone. It is not a subordinate node of the watch.

In the Smart Connect network, the large screen is the central node, the mobile phone and watch are the first-level nodes, and the earphones and speakers are the second-level nodes. Exemplarily, the hierarchical relationship between upper-level nodes and lower-level nodes in the Smart Connect network can be referred to in FIG. 2 . Among them, the mobile phone can also be called an intermediate node, and watches, earphones, and speakers can also be called tail nodes.

In the embodiment of the present application, after the networking is completed, any two electronic devices in the Smart Connect network may support one or more network connection modes, but the electronic devices do not necessarily have established network connections. The network connection mode supported between the electronic devices may be a short-distance wireless network connection mode or a wired network connection mode. Wherein, the wireless network connection mode in which the online detection can be performed by using the method provided in the embodiment of the present application may be referred to as the first network connection mode. For example, the first network connection manner may be a short-distance wireless network connection manner supporting an air interface scanning mechanism. A network connection manner other than the first network connection manner may be referred to as a second network connection manner. Exemplarily, Bluetooth BLE can be the first network connection mode, USB can be the second network connection mode, Wi-Fi, Bluetooth basic rate (base rate, BR) or Bluetooth enhanced rate (enhanced data rate, EDR), etc. can be The first network connection mode may also be the second network connection mode.

In the Zhilian network, between two electronic devices that support the first network connection mode, information such as heartbeat packets can be exchanged through the air interface to send and receive the communication mode of the window. That is, the electronic device at the sending end sends a message through the air interface, and the electronic device at the receiving end receives the message within the receiving window. For example, the air interface sending mode may be broadcast or unicast, and the receiving window may be a scanning window.

If the two electronic devices in the Smart Connect network do not support the first network connection mode but support the second network connection mode, information such as heartbeat packets is exchanged based on the second network connection mode to perform online detection.

In this embodiment of the present application, the priority of the first network connection manner may be higher than that of the second network connection manner. If the two electronic devices in the Zhilian network support both the first network connection method and the second network connection method, then based on the first network connection method, information such as heartbeat packets can be exchanged through the communication mode of the sending and receiving window through the air interface, In order to carry out online detection.

The solution provided by the embodiment of this application can start from the central node of the Smart Connect network, and the upper node sends heartbeat packets to the lower nodes step by step, so as to uniformly perform online detection on the electronic devices in the Smart Connect network, and uniformly determine the Smart Connect network Online and offline status of each electronic device in the system, so that online electronic devices can be used to complete business quickly, directly and collaboratively.

In the Zhilian network, the upper and lower nodes that support the first network connection method can be controlled based on the clock difference and the first network connection method, so as to align the sending timing of the heartbeat packet with the opening timing of the receiving window, referred to as Window alignment or phase alignment, so that the receiving and sending timing of heartbeat packets are synchronized.

Wherein, in the Zhilian network, the upper-level node sends a heartbeat packet to the lower-level node. The upper and lower nodes of the interactive heartbeat packet mentioned here refer to adjacent two-level nodes. For example, the upper-level node refers to the central node, and the lower-level node refers to the first-level node; for another example, the upper-level node refers to the first-level node, and the lower-level node refers to the second-level node. That is to say, the upper node is the electronic device at the sending end of the heartbeat packet, and the lower node is the electronic device at the receiving end of the heartbeat packet.

In the embodiment of the present application, window alignment can be understood as, based on the clock difference between the electronic device at the receiving end and the electronic device at the sending end, it can receive the heartbeat packet sent by the electronic device at the sending end when it is in the window receiving state, so as to efficiently receive Heartbeat packets, reduce power consumption, and quickly perform online detection based on heartbeat packets.

In some embodiments, the window alignment means that the difference between the timing when the electronic device at the receiving end enters the receiving state and the timing when the electronic device at the sending end sends a heartbeat packet is less than or equal to the first preset value. Wherein, the receiving window of the electronic device at the receiving end enters a receiving state after being opened, and can be used to receive heartbeat packets. In this way, the electronic device at the receiving end can open the receiving window at the right time when the electronic device at the sending end sends out a heartbeat packet, thereby ensuring that communication resources will not be wasted due to opening the receiving window too early, nor will it cause damage due to opening the receiving window too late. The heartbeat packet cannot be obtained normally, thus ensuring that the receiving window can receive the heartbeat packet relatively quickly and efficiently.

For example, the time when the receiving window enters the receiving state is earlier than the time when the heartbeat packet is sent. For example, the opening timing of the receiving window is earlier than the sending timing of the heartbeat packet. In this way, when the heartbeat packet is sent, the receiving window is already in the receiving state, and the electronic device at the receiving end can receive the heartbeat packet more quickly and efficiently.

For another example, the receiving window enters the receiving state when the heartbeat packet is sent. For example, the receive window is opened when a heartbeat packet is sent. In this way, when the heartbeat packet starts to be sent, the receiving window happens to be opened and enters the receiving state. Considering the transmission delay, the receiving window is already in the receiving state when the heartbeat packet reaches the electronic device at the receiving end, and the electronic device at the receiving end can be faster and faster. Efficiently receive heartbeat packets.

For another example, before the heartbeat packet reaches the electronic device at the receiving end, the receiving window enters a receiving state. For example, the electronic device at the receiving end can predetermine the timing at which the heartbeat packet arrives at the electronic device at the receiving end according to the sending timing of the heartbeat packet and the pre-calculated transmission delay, so as to open the receiving window in advance before the arrival of the heartbeat packet, so that the receiving window Waiting to receive the heartbeat packet in the state, so that the heartbeat packet can be received quickly and efficiently.

For another example, when the heartbeat packet arrives at the electronic device at the receiving end, the receiving window is opened to enter a receiving state. For example, the electronic device at the receiving end can predetermine the timing at which the heartbeat packet arrives at the electronic device at the receiving end according to the sending timing of the heartbeat packet and the pre-calculated transmission delay, so as to open the receiving window and enter the receiving state when the heartbeat packet arrives, thereby enabling Receive heartbeat packets quickly and efficiently.

For the upper-level and lower-level nodes that support the first network connection mode, after the windows are aligned, after a node sends a small number (such as 1 or 2, etc.) of heartbeat packets, the lower-level nodes of the node can quickly A heartbeat packet was detected. That is to say, after the receiving and sending timing of the heartbeat packet is synchronized, the lower-level nodes can receive the heartbeat packet quickly, accurately and efficiently within the receiving window, thereby reducing the number of interactions of the heartbeat packet per unit time and improving the reception of the heartbeat packet. Reliability, reduce communication cost and power consumption, and realize fast, accurate and timely online detection among multiple devices.

In addition, for electronic devices that only support the second network connection mode, heartbeat packets and heartbeat response messages can be exchanged between upper and lower nodes based on the clock difference and the second network connection mode.

In this way, the solution can realize fast, accurate and timely online detection of each electronic device in the Smart Connect network that supports the first network connection mode or the second network connection mode.

The following will take the central node, first-level node and second-level node in the smart connection network shown in Figure 1A and Figure 2, the air interface transmission mode of the heartbeat packet is broadcast, and the receiving window of the heartbeat packet is the scanning window The online detection method provided in the embodiment of the application will be described. The method can include:

After the upper-lower relationship of each node in the Zhilian network is determined, refer to the sequence diagram shown in Figure 3A. The large screen acts as the central node and starts broadcasting heartbeat packets to mobile phones and watches as first-level nodes at time t1. The heartbeat packet group may include N (N is an integer greater than 1) heartbeat packets sent sequentially at preset intervals (eg, 20 ms, 30 ms, etc.) within a preset period. In some embodiments, each heartbeat packet in the heartbeat packet group carries its own sending timestamp, for example, the first heartbeat packet carries its own sending timestamp t1, and the X1th heartbeat packet carries its own sending time Poke tX1.

Referring to FIG. 3A, the mobile phone as a first-level node sends a heartbeat response message to the large screen after receiving the X1th (X1 is an integer greater than or equal to 1 and less than or equal to N) heartbeat packets at time tr1.

In some embodiments, the heartbeat response message sent by the mobile phone to the large screen includes tr1 and the sending time stamp tX1 of the X1th heartbeat packet. In some other embodiments, the heartbeat response message sent by the mobile phone to the large screen includes tr1 and the identifier of the X1th heartbeat packet, and the large screen can determine the sending time stamp tX1 of the X1th heartbeat packet according to the identifier of the X1th heartbeat packet .

After the large screen receives the heartbeat response message sent by the mobile phone at time tnow1, it calculates the transmission delay between the large screen and the mobile phone as tdelay1=(tnow1-tX1)/2. According to the transmission delay, the clock difference between the mobile phone and the large screen is tC1=tr1-tX1-tdelay1. The large screen can send the clock difference to the mobile phone, so that the windows between the mobile phone and the large screen can be aligned according to the clock difference, so as to synchronize the receiving and sending timing of heartbeat packets. Exemplarily, the interaction process about the clock difference between the large screen and the mobile phone can be referred to FIG. 3B.

In the solution described in the above embodiments, the large screen terminal calculates the clock difference between the mobile phone and the large screen and sends it to the mobile terminal. In some other embodiments, the mobile phone terminal can also calculate the clock difference with the large screen by itself, and the embodiment of the present application does not limit the device terminal that calculates the clock difference.

Wherein, the clock difference is used to represent the difference between the local clocks of two electronic devices. The electronic device can obtain a local clock based on its own operating system. For example, the java of the android system uses the interface System.nanoTime() to obtain the relative clock, and the embedded system OS of the non-android system can use the interface getTickCount() to obtain the relative clock, etc. The local clock may be a relative clock, and the relative clock may be different from the world time displayed by the terminal device to the user. The local clock can be, for example, the time after power-on or the time from a certain reference time (for example, January 1, 1970) to the present. For example, the local clock of the large screen is the time after booting, and the local clock of the mobile phone is also the time after booting, and the clock difference is 3658*10 ⁹ ns. For another example, the local clock of the large screen is the time after power-on, and the local clock of the mobile phone is the time from January 1, 1970 to the present.

Similarly, referring to Fig. 3A, after receiving the X2th (X2 is an integer greater than or equal to 1 and less than or equal to N) heartbeat packets at the time tr2, the watch as a first-level node sends a heartbeat response message to the large screen and carries tr2 and the sending timestamp tX2 of the X2th heartbeat packet. After the large screen receives the heartbeat response message sent by the watch at tnow2, it calculates the transmission delay tdelay2=(tnow2-tX2)/2. The clock difference between the watch and the large screen is tC2=tr2-tX2-tdelay2.

If the first network connection mode is supported between the central node and the first-level node, the central node and the first-level node can control the broadcasting timing of the subsequent heartbeat packet and/or the opening timing of the scanning window according to the clock difference, so that the heartbeat packet The broadcast timing is aligned with the opening timing of the scanning window. That is, the window is aligned between the central node and the first-level node, so that the scanning window is in the receiving state when the heartbeat packet is broadcast, and the timing of receiving and sending the heartbeat packet is synchronized. After the window is aligned, the first-level node can quickly and accurately receive the heartbeat packet broadcast by the central node within the scanning window, thereby reducing the number of interactions of the heartbeat packet per unit time, reducing communication costs and power consumption, and improving heartbeat packet reception Reliability, to achieve fast, accurate and timely online detection between devices.

For example, in the Smart Connect network shown in Figure 1A, the first network connection method Bluetooth BLE is supported between the large screen and the mobile phone, and the broadcast timing and/or scanning window of subsequent heartbeat packets can be controlled between the large screen and the mobile phone according to the clock difference The opening timing of the mobile phone makes the scanning window of the mobile phone also in the receiving state when the large screen broadcasts the heartbeat packet. In this way, the mobile phone can quickly and accurately receive the heartbeat packets broadcast on the large screen within the scanning window, thereby reducing the number of heartbeat packet interactions per unit time, reducing invalid broadcast and scanning duty cycles, and improving the reliability of heartbeat packet reception , reduce communication cost and power consumption, and realize fast, accurate and timely online detection between devices.

Similarly, the large screen and the watch support Bluetooth BLE in the first network connection mode, and the large screen and the watch can control the broadcast timing of subsequent heartbeat packets and/or the opening timing of the scan window according to the clock difference, so that the large screen The scan window of the watch is also in the receiving state when the heartbeat packet is broadcast. In this way, the watch can quickly and accurately receive the heartbeat packets broadcast on the large screen within the scanning window, thereby reducing the number of interactions of heartbeat packets per unit time, reducing invalid broadcasts and scanning duty cycles, and improving the reliability of heartbeat packet reception , reduce communication cost and power consumption, and realize fast, accurate and timely online detection between devices.

In some embodiments, when the first network connection mode is Bluetooth BLE, a broadcast message for sending the heartbeat packet may be a non-connectable broadcast ADV_NONCONN_IND message. According to the Bluetooth protocol, this type of broadcast message does not require a special response message to reply, so it can reduce the bandwidth occupation of the response message packet, reduce the number of message interactions during the online detection process, save power consumption, simplify the interaction process, and improve online detection. s efficiency.

In the embodiment of the present application, multiple different strategies may be adopted for window alignment to control the timing of broadcasting subsequent heartbeat packets and/or the timing of opening the scan window according to the clock difference.

For example, in the first strategy, between the large screen and the mobile phone, and between the large screen and the watch, window alignment is performed according to the first heartbeat packet in the heartbeat packet group broadcast at time t1. Referring to Fig. 3A, the large screen periodically broadcasts heartbeat packet groups at the time t1+m*T1 corresponding to the local clock according to the first preset period T1, where m is a positive integer. Based on the clock difference, the mobile phone controls the time t1+m*T1+tC1 corresponding to the local clock, and periodically opens the scanning window to receive heartbeat packets. In this way, the timing of broadcasting the heartbeat package group on the large screen is consistent with the activation timing of the mobile phone scanning window. When the first heartbeat package in the large screen broadcasting heartbeat package When the heartbeat packet arrives at the mobile phone, the scanning window of the mobile phone has already been opened, which can improve the detection efficiency and response speed of the heartbeat packet, reduce invalid broadcast and scanning duty cycle, and realize fast, accurate and timely connection and online connection between the large screen and the mobile phone detection.

Similarly, the large screen periodically broadcasts the heartbeat packet group at the time t1+m*T1 corresponding to the local clock according to the first preset period T1. Based on the clock difference, the watch is controlled to periodically open the scan window at the time t1+m*T1+tC2 corresponding to the local clock to receive heartbeat packets. Exemplarily, a schematic diagram of comparison before and after window alignment corresponding to the first strategy can be referred to in FIG. 4 .

In this scheme, the first heartbeat packet in the heartbeat packet group may be a target heartbeat packet (also called a target message) corresponding to the mobile phone and the watch. Based on this scheme, the mobile phone and the watch can enter the receiving state when the large screen sends the heartbeat packet group (that is, the first heartbeat packet in the heartbeat packet group), that is, they can enter the receiving state when the large screen sends the target heartbeat packet in the heartbeat packet group. Receive status, so that the target heartbeat packet can be quickly received, and the online detection efficiency can be improved.

Or, in this scheme, the X1 heartbeat packet in the heartbeat packet group is the target heartbeat packet corresponding to the mobile phone. Based on this scheme, the mobile phone can send the heartbeat packet group (that is, send the first heartbeat packet in the heartbeat packet group) on the large screen. packet) into the receiving state, and is in the receiving state when sending the target heartbeat packet on the large screen, so that the target heartbeat packet can be quickly received and the online detection efficiency is improved. In this scheme, the X2 heartbeat packet in the heartbeat packet group is the target heartbeat packet corresponding to the watch. Based on this scheme, the watch can enter the receiving state when sending the heartbeat packet group on the large screen, and be in the receiving state when sending the target heartbeat packet on the large screen. Receive status, so that the target heartbeat packet can be quickly received, and the online detection efficiency can be improved.

Exemplarily, the large screen broadcasts the heartbeat packet group at 16:00 corresponding to the local clock for the first time (that is, broadcasts multiple heartbeat packets in a heartbeat packet group sequentially at a preset interval such as 20ms at 16:00), and T1 is 5 minutes (that is, the big screen broadcasts a heartbeat packet every 5 minutes), the clock difference between the mobile phone and the big screen is 30 minutes, and the clock difference between the watch and the big screen is 2 hours. After window alignment based on the clock difference, the large screen starts broadcasting heartbeat packets at 16:05, 16:10, 16:15... corresponding to the local clock; 40, 16:45... Open the scanning window to receive the heartbeat packet; the watch opens the scanning window at 18:05, 18:10, 18:15... corresponding to the local clock to receive the heartbeat packet.

As another example, the large screen broadcasts the heartbeat packet group at the 30ns corresponding to the local clock for the first time (that is, broadcasts multiple heartbeat packets in a heartbeat packet group sequentially at a preset interval such as 20ms at the 30ns), T1 is 5 Minutes, the clock difference between the mobile phone and the big screen is 30 minutes, and the clock difference between the watch and the big screen is 2 hours. After window alignment based on the clock difference, the large screen starts broadcasting the heartbeat packet group at the 5th minute 30ns, the 10th minute 30ns, the 15th minute 30ns... of the local clock; the mobile phone respectively at the 35th minute corresponding to the local clock 30ns, 30ns at the 40th minute, 30ns at the 45th minute... Open the scan window to receive the heartbeat packet; the watch opens at the 2nd hour, 5min 30ns, 2nd hour, 10min 30ns, 2nd hour, 15min 30ns... Scan windows for heartbeat packets.

In addition, since the mobile phone receives the heartbeat packet of the large-screen broadcast for the first time at the time tX1 corresponding to the X1-th heartbeat packet in the heartbeat packet, the probability of receiving the X1-th heartbeat packet in the heartbeat packet again is relatively high. When the windows are aligned, the mobile phone can adjust the start scanning time of the heartbeat packet to the time corresponding to the X1th heartbeat packet. In this way, the window alignment accuracy is higher, and the mobile phone can receive the heartbeat packets sent in the broadcast window more quickly and accurately in the scan window, thereby reducing the number of heartbeat packet interactions per unit time and improving the reliability of heartbeat packet reception , reduce communication cost and power consumption, and realize fast, accurate and timely online detection between devices.

Therefore, in the second strategy, the mobile phone and the watch perform window alignment according to the X1th heartbeat packet and the X2th heartbeat packet corresponding to each other. Specifically, the large screen periodically broadcasts the heartbeat packet group at the time t1+m*T1 corresponding to the local clock according to the first preset period T1. According to the sending time tX1 of the X1th heartbeat packet received for the first time, the mobile phone adjusts the opening timing of the subsequent heartbeat packet scanning window to perform window alignment. Based on the clock difference, the mobile phone controls the time tX1+m*T1+tC1 corresponding to the local clock, that is, the moment when the X1th heartbeat packet is broadcast on the large screen, and periodically opens the scanning window to receive the heartbeat packet.

Similarly, the large screen periodically broadcasts heartbeat packets at the time t1+m*T1 corresponding to the local clock according to the first preset period T1. According to the sending time tX2 of the X2th heartbeat packet received for the first time, the watch adjusts the opening timing of the subsequent heartbeat packet scanning window for window alignment. Based on the clock difference, the watch is controlled at the time tX2+m*T1+tC2 corresponding to the local clock, that is, the moment when the X2 heartbeat packet is broadcast on the large screen, and periodically opens the scanning window to receive the heartbeat packet. Exemplarily, a schematic diagram of comparison before and after window alignment corresponding to the second strategy can be referred to FIG. 5 .

In this scheme, the X1th heartbeat packet in the heartbeat packet group is the target heartbeat packet corresponding to the mobile phone, and the X2th heartbeat packet in the heartbeat packet group is the target heartbeat packet corresponding to the watch. Based on this solution, the mobile phone and watch can be in the receiving state when the large screen sends the target heartbeat packet, so that the target heartbeat packet can be quickly received and the online detection efficiency is improved.

Exemplarily, the large screen starts to broadcast the heartbeat packet group (including multiple heartbeat packets broadcast in sequence according to the preset interval) at 16:00 corresponding to the local clock for the first time, tX1 is 16:00:01, and tX2 is 16:00 : 02, T1 is 5 minutes, the clock difference between the mobile phone and the big screen is 30 minutes, and the clock difference between the watch and the big screen is 2 hours. After window alignment based on the clock difference, the large screen broadcasts heartbeat packet groups at 16:05, 16:10, 16:15... corresponding to the local clock; :40:01, 16:45:01...open the scan window to receive the heartbeat packet; the watch respectively opens the scan window to receive the heartbeat packet.

In the first strategy or the second strategy, the large screen periodically broadcasts a heartbeat packet group at t1+m*T1, and the mobile phone and the watch respectively open the scanning window according to the timing corresponding to their own window alignment, so as to receive the heartbeat Bag.

In addition, after receiving the Xi-th (i is a positive integer from 1 to N) heartbeat packet broadcast by the large-screen for the first time, the lower-level node of the big screen has a higher probability of receiving the Xi-th heartbeat packet in the heartbeat packet again. Therefore, in the third strategy, the large screen can adjust the broadcast timing of the subsequent heartbeat packet group to the sending time corresponding to the Xi-th heartbeat packet, that is, the large screen can adjust the broadcast timing of the subsequent heartbeat packet group according to tXi. When the big screen has multiple lower-level nodes, the big screen can broadcast a heartbeat packet group to multiple lower-level nodes, instead of broadcasting a heartbeat packet group to each lower-level node, so as to simplify the sending process of heartbeat packets and reduce message interaction The number of strips saves power consumption. At this time, the large screen can adjust the broadcast timing of the subsequent heartbeat packet group according to the front timing (also called tX0) of tXi corresponding to multiple lower-level nodes, so that after window alignment of multiple lower-level nodes, even It can efficiently, quickly and timely scan the heartbeat packets of large-screen broadcasts.

For example, the mobile phone receives the X1-th heartbeat packet in the heartbeat packets broadcast on the large screen for the first time, and the watch receives the X2-th heartbeat packet in the heartbeat packets broadcast on the large-screen broadcast for the first time. If the sending time tX1 corresponding to the X1 heartbeat packet is earlier, that is, X0 is X1 and tX0 is tX1, then the large screen will periodically broadcast the heartbeat packet group at the sending time corresponding to the X1 heartbeat packet. That is, the large screen periodically broadcasts heartbeat packets at the time tX1+m*T1. The mobile phone opens the scanning window to receive the heartbeat packet at the time tX1+m*T1+tC1; the watch opens the scanning window to receive the heartbeat packet at the time tX2+m*T1+tC2. Exemplarily, a schematic diagram of comparison before and after window alignment corresponding to the third strategy can be referred to FIG. 6 .

In this scheme, the first (X1-X1+1) heartbeat packet in the heartbeat packet group is the target heartbeat packet corresponding to the mobile phone, and the X2-X1+1 heartbeat packet in the heartbeat packet group is the target corresponding to the watch. heartbeat packet. Based on this scheme, the mobile phone and the watch can enter the receiving state when the large screen sends the heartbeat packet group (that is, the first heartbeat packet in the heartbeat packet group), so that the target heartbeat packet can be quickly received and the online detection efficiency is improved. For example, if X1 is 2 and X2 is 3, the large screen will periodically broadcast the heartbeat packet group at the sending time corresponding to the second heartbeat packet. The first (ie 2-2+1) heartbeat packet in the heartbeat packet group It is the target heartbeat packet corresponding to the mobile phone, and the second (ie 3-2+1) heartbeat packet in the heartbeat packet group is the target heartbeat packet corresponding to the watch.

Or, if the sending time tX2 corresponding to the X2th heartbeat packet is earlier, that is, X0 is X2 and tX0 is tX2, then the large screen will periodically broadcast the heartbeat packet group at the sending time corresponding to the X2th heartbeat packet. That is, the large screen periodically broadcasts heartbeat packets at the time tX2+m*T1. The mobile phone opens the scanning window to receive the heartbeat packet at the time tX2+m*T1+tC1; the watch opens the scanning window to receive the heartbeat packet at the time tX2+m*T1+tC2.

In this scheme, the first (X1-X2+1) heartbeat packet in the heartbeat packet group is the target heartbeat packet corresponding to the watch, and the X1-X2+1 heartbeat packet in the heartbeat packet group is the target corresponding to the mobile phone heartbeat packet. Based on this solution, mobile phones and watches can enter the receiving state when the large screen sends heartbeat packets, so that they can quickly receive target heartbeat packets and improve online detection efficiency.

Exemplarily, the large screen starts to broadcast the heartbeat packet group at 16:00 corresponding to the local clock for the first time, tX1 is 16:00:01, tX2 is 16:00:02, tX1 is ahead of tX2, T1 is 5 minutes, the mobile phone The clock difference with the big screen is 30 minutes, and the clock difference between the watch and the big screen is 2 hours. After window alignment based on the clock difference and tX1, the large screen starts broadcasting heartbeat packets at 16:05:01, 16:06:01, 16:15:01... corresponding to the local clock; Corresponding 16:35:01, 16:40:01, 16:45:01... Open the scanning window to receive the heartbeat packet; the watch is at 18:05:02, 18:06:02, 18:02 corresponding to the local clock 15:02...opened scan window to receive heartbeat packets.

In the second and third strategies, the timing of broadcasting the heartbeat packet on the large screen is inconsistent with the timing of opening the scanning window on the mobile phone, and the timing of broadcasting the heartbeat packet on the large screen is also inconsistent with the timing of opening the scanning window on the watch, but the broadcasting timing is consistent with the timing of the scanning window. The difference between the opening timings is small, less than or equal to the first preset value. This situation also belongs to window alignment, and the mobile phone and watch can also receive heartbeat packets efficiently, quickly, accurately, and in time for online detection. .

In addition, if the central node has only one first-level node, and the first-level node receives the Xth heartbeat packet in the heartbeat packet group broadcast by the central node at time t1 for the first time, the central node and the first-level node can be based on the clock difference tC performs window alignment with the Xth heartbeat packet. For example, the central node periodically broadcasts the heartbeat packet group at the time tX+m*T1 corresponding to the local clock according to the first preset period T1. Based on the clock difference tC, the first-level node controls to periodically open the scan window to receive heartbeat packets at the time tX+m*T1+tC corresponding to the local clock.

In this scheme, the first heartbeat packet in the heartbeat packet group is the target heartbeat packet corresponding to the first-level node, and the first-level node can enter the receiving state when the central node sends the target heartbeat packet, so that it can quickly receive the target heartbeat packet. Improve online detection efficiency.

In addition, if the scheme provided by the embodiment of the present application is not used for window alignment between the first-level node and the central node, as shown in Figure 7, the first-level node usually needs multiple scanning windows to receive the heartbeat packet sent by the large screen. The receiving efficiency of the heartbeat packet is poor, the number of times the heartbeat packet is sent is large, the number of scans of the scanning window is large, and the power consumption of the first-level node and the central node is large.

In the embodiment of the present application, after the first-level node receives the heartbeat packet sent by the large screen for the first time, it sends the heartbeat packet to the second-level node to perform online detection on the second-level node. For example, in the Smart Connect network shown in FIG. 1A , after receiving the heartbeat packet for the first time, the mobile phone of the first-level node sends the heartbeat packet to the earphone and speaker of the second-level node.

Among them, if the first network connection mode is supported between the first-level node and the second-level node, the window alignment between the first-level node and the second-level node can be performed according to the clock difference, and the timing and/or The timing when the secondary node opens the scanning window makes the scanning window enter the receiving state when the primary node broadcasts the heartbeat packet. After the window is aligned, the second-level node can quickly and accurately receive the heartbeat packet broadcast by the first-level node within the scanning window, thereby reducing the number of heartbeat packet interactions per unit time, improving the reliability of heartbeat packet reception, and reducing communication. Cost and power consumption, to achieve fast, accurate and timely online detection between devices.

For example, in the Smart Connect network shown in FIG. 1A , the first network connection mode Bluetooth BLE is supported between the mobile phone and the headset. After the mobile phone receives the heartbeat packet for the first time, referring to FIG. 3A , it starts to broadcast the heartbeat packet group at time tA, so that the earphone can receive the heartbeat packet in the heartbeat packet group. If the earphone receives the X3th heartbeat packet, and the clock difference between the earphone and the mobile phone is tC3, the above strategy can be used for window alignment between the earphone and the mobile phone based on the clock difference tC3. For example, when adopting the first strategy, the mobile phone periodically broadcasts the heartbeat packet group at the time tA+m*T1 corresponding to the local clock according to the first preset period T1. Based on the clock difference, the mobile phone periodically opens the scanning window at the time tA+m*T1+tC3 corresponding to the local clock to receive the heartbeat packet. In this way, the timing of the mobile phone broadcasting the heartbeat packet is consistent with the activation timing of the earphone scanning window. Fast, accurate and timely connection and online detection between mobile phone and headset.

If the second network connection method is supported between the first-level node and the second-level node but not the first network connection method, the first-level node can periodically send the second network connection method to the second-level network according to the first preset period T1. The node sends a heartbeat packet, and the secondary node can wake up periodically and respond in real time according to the clock difference and the first preset period T1. In this way, the secondary node can periodically wake up and run and respond to the heartbeat, can receive and respond to the heartbeat packet efficiently, accurately, and in a timely manner, reduce disordered heartbeat packets and repeated heartbeat responses, and save power consumption of the secondary node.

Exemplarily, Wi-Fi is supported between the mobile phone and the speaker, and Wi-Fi here belongs to the second network connection mode and does not support the first network connection mode. As shown in Figure 8, the mobile phone sends a heartbeat packet to the speaker at time tA based on the Wi-Fi connection, and carries the sending time stamp tA. After the speaker receives the heartbeat packet at time tr4, it replies a response message to the mobile phone, and carries the receiving time stamp tr4. After the mobile phone receives the response message sent by the speaker at time tnow4, it calculates the transmission delay tdelay4=(tnow4-tA)/2. The clock difference between the mobile phone and the speaker is tC4=tr4-tA-tdelay4. The mobile phone can notify the speaker of the clock difference, so that the speaker can wake up regularly to receive the heartbeat packet according to the clock difference and the first preset period T1.

Subsequently, based on the Wi-Fi connection, the mobile phone periodically sends a heartbeat packet group from the kernel bottom layer protocol stack to the speaker at the time tA+m*T1 corresponding to the local clock. The speaker periodically wakes up and runs at the time tA+m*T1+tC4 corresponding to the local clock, and responds in real time after receiving the heartbeat packet through the Wi-Fi connection, which can reduce disordered heartbeat packets and repeated heartbeat responses. And there is no need to perform window alignment like the first network connection method.

That is to say, in the Smart Connect network shown in Figure 1A, between the mobile phone as the first-level node and the earphone as the second-level node, Bluetooth BLE in the first network connection mode is supported, and window alignment can be performed based on the clock difference. And periodically exchange heartbeat packets after the windows are aligned, so as to perform online detection of electronic equipment. The mobile phone as the first-level node and the speaker as the second-level node support Wi-Fi in the second network connection mode, but do not support the first network connection mode. Heartbeat packets can be exchanged periodically based on the clock difference, thereby On-line inspection of electronic equipment.

The online detection method provided by the embodiment of the present application is described above by taking the central node, the first-level node and the second-level node in the smart connection network shown in FIG. 1A as examples. When the Wi-Fi network also includes nodes at other levels (such as third-level nodes and fourth-level nodes), the central node sends the heartbeat packet to the first-level node, and the first-level node sends the heartbeat packet to the second-level node. The heartbeat packet can be sent to the third-level node, and the third-level node can also send the heartbeat packet to the fourth-level node, and so on, which will not be described here. In this way, heartbeat packets can be efficiently, quickly and accurately received between adjacent upper and lower nodes (or directly connected upper and lower nodes) in the entire network, thereby improving the receiving efficiency of heartbeat packets and reducing the number of sending and receiving of heartbeat packets and It can reduce the power consumption of electronic devices, so that multiple electronic devices in the network can be detected quickly, timely and accurately based on heartbeat packets, and the number of electronic devices that can be connected to the Smart Connect network can also be increased.

Therefore, this solution can sequentially transmit heartbeat packets between the upper and lower nodes in the entire SmartConnect network (this can also be called heartbeat synchronization in the entire SmartConnect network), reducing disordered heartbeats and improving the performance of the SmartConnect network. Each electronic device performs unified and orderly online detection, and then the online electronic device can be used to perform business quickly, directly and collaboratively.

In addition, when the smart connection network is formed before the service request, the efficiency of network heartbeat synchronization can be improved, and the device status and online and offline responses in the smart connection network can be more real-time and accurate. Moreover, it can reduce the energy consumption of background networking, make the network orderly, and improve the network stability in the case of a large number of devices.

It can be understood that the smart connection network shown in Figure 1A is only an example, and the smart connection network can also have different network topologies, and can also have more electronic devices (such as smart lights, smart curtains, smart remote control or electronic lock, etc.) and more complex network connection relationship. SmartConnect networks with various structures can use the above method to exchange heartbeat packets for online detection.

In addition, in some embodiments of the present application, when a certain node enters the screen-on state, it is usually executing services, so it is not sensitive to power consumption, and the scanning action has little impact on the power consumption of the node. Therefore, when the node opens the scan window to align the windows, the duty cycle of the scan window can also be larger to ensure that the node can receive heartbeat packets in a timely and fast manner, reducing heartbeat misses caused by large interference The reception of the package. Conversely, when the node enters the off-screen state, the duty cycle of the scan window may be smaller to save power consumption.

In some other embodiments of the present application, the duty cycle of the scan window may also be different if the device types of the nodes are different. For example, if the node is not sensitive to power consumption, the duty cycle of the scanning window can be larger to ensure that heartbeat packets can be received in a timely and fast manner, and to reduce missed reception of heartbeat packets due to large interference. If the node is more sensitive to power consumption, the duty cycle of the scan window can be smaller to save power consumption.

In addition, in the embodiment of the present application, the duration of the node scanning window can be preset, and the duration is longer than the duration of one heartbeat packet, for example, it can be set to the duration of three heartbeat packets, so as to make it possible to receive The heartbeat packet is received and the scanning window is short, so that the power consumption of the node is small.

In some embodiments of the present application, when a certain node is performing services, it may suspend sending heartbeat packet groups according to the first preset period T1. The central node can also trigger and adjust the time to start periodically sending the heartbeat packet group. For example, when the central node is performing services, it may suspend sending heartbeat packet groups according to the first preset period T1. After the service ends, the central node may trigger the heartbeat packet group to be sent periodically according to the first preset period T1 starting from time tAdj. The central node can notify the first-level node of the adjusted time tAdj, and the first-level node adjusts the scan window accordingly for window alignment. Subsequent nodes transmit the adjusted time tAdj to their respective subordinate nodes in turn.

In addition, in some embodiments, the central node may trigger recalculation of the clock difference according to the preset second preset period T2, and perform clock difference calibration between nodes at all levels. When the clock difference changes or when the change of the clock difference is greater than or equal to the second preset value, the nodes in the Smart Connect network update the clock difference, and perform window alignment based on the clock difference again. Wherein, the second preset period T2 is greater than the first preset period T1. For example, the first preset period T1 may be 5 minutes, and the second preset period may be 1 hour. The central node broadcasts a heartbeat packet every 5 minutes, and triggers an update of the clock difference every 1 hour.

In some technical solutions, as time goes by, the clock difference between nodes in the Smart Connect network may change, and the second preset period T2 may be a preset experience value, which is the same as the cumulative change of the clock difference Threshold related. That is to say, after the interval T2, the cumulative change of the clock difference may have exceeded the threshold, so the central node may trigger recalculation of the clock difference.

In some other embodiments, if a certain node finds that the number of heartbeat packets between the heartbeat packet received this time and the heartbeat packet received for the first time is greater than or equal to the third preset value, it may be that the clock difference is relatively large. Large changes, so the central node can be requested to trigger an update clock difference. For example, the third default value is 3, the mobile phone receives the second heartbeat packet of the large-screen broadcast for the first time, if the mobile phone receives the seventh heartbeat packet of the large-screen broadcast this time, 7-2=5 is greater than the third preset If the value is 3, the clock difference may have changed greatly, so the mobile phone can request the large screen to trigger recalculation of the clock difference. Then, each node performs window alignment again based on the clock difference.

In other embodiments, if a node finds that the number of heartbeat packets between the heartbeat packet received this time and the heartbeat packet received for the first time is greater than or equal to the fourth preset value, it can report to the node's The superior node, the superior node of the node can request the central node to trigger to update the clock difference. For example, the fourth preset value is 4, the headset receives the third heartbeat packet broadcast by the mobile phone for the first time, if the headset receives the ninth heartbeat packet broadcast by the mobile phone this time, 9-3=6 is greater than the fourth preset value 4 , the clock difference may have changed greatly, so the headset can report to the mobile phone, and the mobile phone can request the large screen to trigger recalculation of the clock difference. Then, each node performs window alignment again based on the clock difference.

In some other embodiments, if a node finds that the number of heartbeat packets between the heartbeat packet received by the node's subordinate node and the heartbeat packet received for the first time is greater than or equal to The fifth preset value may request the central node to trigger to update the clock difference. For example, if the fifth preset value is 3, the mobile phone determines that the headset has received the 8th heartbeat packet broadcast by the mobile phone this time, if the headset receives the 4th heartbeat packet broadcast by the mobile phone for the first time, then 8-4=4 is greater than the fifth preset If the value is set to 3, the clock difference may have changed greatly, so the mobile phone can request the large screen to trigger recalculation of the clock difference. If the node is the central node, it will directly trigger to update the clock difference in this case. Then, each node performs window alignment again based on the clock difference.

In addition, in the embodiment of this application, if a new node is added to the Zhilian network, each node will re-determine the network topology relationship, recalculate the clock difference, and perform window alignment, so that after the window alignment, exchange heartbeat packets for online detection. If a node in the Zhilian network leaves, each node will re-determine the network topology relationship, recalculate the clock difference and perform window alignment, so as to exchange heartbeat packets for online detection after window alignment. If the central node changes due to the addition of a new node or the departure of a node, the new central node triggers recalculation of the clock difference and window alignment, so that heartbeat packets can be exchanged for online detection after window alignment.

In some embodiments, as mentioned above, after each device in the Smart Connect network is successfully established, it may be determined that each electronic device is online. If it is found that an electronic device has left during the online detection through the heartbeat packet, the offline information of the electronic device can be notified to the central node or to each electronic device in the Zhilian network, so that the central node or each electronic device can be unified. Know the online status of each electronic device.

In the Zhilian network, after a node receives the heartbeat packet sent by the upper node of the node for the first time, it sends the heartbeat packet group to the lower node of the node. Subsequently, the node periodically sends the heartbeat packet group to the subordinate node according to T1 according to the time when the heartbeat packet is sent to the subordinate node for the first time. Therefore, under normal circumstances, when the node subsequently sends the heartbeat packet group to the subordinate node according to T1, it has already received the heartbeat packet from the superior node. If the node does not receive the heartbeat packet from the upper-level node when it sends the heartbeat packet group to the lower-level node according to the cycle, it may be due to network reasons, changes in the clock difference, or the departure of the upper-level node. Send a heartbeat packet group to the lower-level node in a normal period, and trigger abnormal recovery processing. For example, after the windows are aligned, the mobile phone determines to start broadcasting heartbeat packets to the earphones at 18:05, 18:10, 18:15... in a period of 5 minutes; If there is an abnormality in the heartbeat packet, the heartbeat packet group will be broadcast to the earphone at 18:05 according to the normal cycle, and the exception recovery process will be triggered.

During the abnormal recovery process, if the node receives the heartbeat packet from the superior node within the preset time period, it can perform clock difference calibration according to the received heartbeat packet; if the intermediate node has not received the heartbeat packet from the The heartbeat packet of the upper-level node can determine whether the upper-level node has left, whether it is necessary to re-determine the network topology relationship, whether it is necessary to recalculate the clock difference and other related exception handling.

In the above embodiments of the present application, window alignment is used to send and receive heartbeat packets, so as to perform online detection. In other embodiments, the clock difference can also be determined based on other messages other than heartbeat packets, and window alignment can also be used to exchange other target information instead of sending and receiving heartbeat packets, so that other applications other than online detection can be performed, The embodiment of the present application does not limit the application scenarios and scope of window alignment. In this way, the electronic device can quickly and accurately receive the target information within the receiving window, thereby reducing the number of message interactions per unit time, reducing communication costs and power consumption, and improving the reliability of receiving target information. The sending and receiving of target information between electronic devices is more rapid, accurate and timely.

For example, the target information may include basic information of an electronic device in the Smart Connect network or changes in network capability information. Using the solution provided by the embodiment of this application, other electronic devices in the Zhilian network can quickly and accurately receive the target information within the receiving window after the windows are aligned, so as to know the changes in the basic information of the electronic device or network capability information etc., so that other electronic devices can perform corresponding adaptation or other related processing according to the changed basic information or network capability information of the electronic device. This solution can improve the reliability of receiving target information, improve the efficiency of multiple electronic devices in the Smart Connect network synchronously obtaining the basic information of an electronic device or the change of network capability information, and make the target information between multiple electronic devices in the Smart Connect network Sending and receiving more quickly, accurately and timely.

For example, the basic information of an electronic device may include at least one of the following: the identification (device ID) of the electronic device, the name (device name) of the electronic device (device name), the type (device type) of the electronic device, the network identification (Network ID), the electronic device At least one of the weight information of the electronic device, the role information of the electronic device, and the version information of the electronic device. Among them, the identification of the electronic device is used to uniquely identify an electronic device; the name of the electronic device is the name of the electronic device defined by the user or the name defined by the factory of the electronic device; the type of the electronic device indicates which type the electronic device belongs to, for example, the type is: Mobile phones, PCs, wearables, earphones, glasses, speakers, car phones, smart screens or car phones, etc. The network identifier is a unique network identifier assigned by the network to the electronic device after the electronic device is connected to the network, for example, it may be a unique device identifier (UDID). The version information of the electronic device indicates the version number of the current system of the electronic device. For network capability information, please refer to the relevant description above.

Exemplarily, other electronic devices in the Zhilian network previously saved the IP address of the electronic device 1 so as to transmit business data with the electronic device 1, and the target information is that the IP address of the electronic device 1 has been changed. Other electronic devices in the Smart Connect network can efficiently and accurately receive the target information based on window alignment. After receiving the target information, other electronic devices in the Zhilian network can update the IP address of the electronic device 1 saved before.

As another example, the previous network capability of the electronic device 1 does not support point-to-point (point to point, P2P) communication, and the target information is that the electronic device 1 supports P2P communication.
