Description

Information synchronization method, system and electronic equipment between multiple devices

This application claims the priority of a Chinese patent application filed with the State Intellectual Property Office on September 30, 2019, the application number is 201910944497.5, and the invention title is "a method, system and electronic device for information synchronization between multiple devices". The entire content is incorporated into this application by reference.

Technical field

This application relates to the field of communication technology, and in particular to a method, system and electronic device for information synchronization between multiple devices.

Background technique

With the development of smart home technology, a user or family often has multiple electronic devices that can communicate with each other. Various electronic devices generally have their own device characteristics. For example, mobile phones have better portability, TV screens have better display effects, and speakers have better sound quality. In order to give full play to the device characteristics of different electronic devices, more and more functions need to be completed by multiple electronic devices working together.

For example, there may be multiple electronic devices that support voice wake-up in the user's home, and the wake-up words of these multiple electronic devices are the same (for example, "小艺小艺"). Then, after the user speaks the wake-up word, multiple devices that detect the wake-up word need to interact with each other's device information (such as device type, whether to connect a headset, etc.), and then, each device can pass through the received device information according to the received device information. The preset wake-up decision algorithm determines which device is awakened this time in response to the wake-up word input by the user.

It can be seen that when multiple electronic devices work in coordination, they need to interact with each other's respective device information before they can further determine specific coordination steps or coordination results based on the device information of each device. Obviously, multiple interactions between devices will not only increase the time-consuming response of the entire device's collaborative work, but also increase the power consumption of the electronic device.

Summary of the invention

The present application provides a method, system and electronic device for information synchronization between multiple devices, which can reduce the time consumption in the process of multi-device collaborative work, reduce the power consumption of the electronic device, and improve the user experience in the multi-device collaborative scenario.

Detailed ways

The implementation of this embodiment will be described in detail below in conjunction with the accompanying drawings.

The method for information synchronization between multiple devices provided by the embodiment of the present application can be applied to a device group 200 shown in FIG. 1, and each electronic device 100 in the device group 200 can communicate with each other. The device group 200 may also be referred to as an information synchronization system. For example, the electronic devices 100 may communicate with each other through a local area network (LAN) or a wide area network (WAN).

Exemplarily, the user can log in to the application server using the same user account through a mobile phone, a tablet computer, a smart speaker, a smart watch, and a laptop computer. At this time, the mobile phone, tablet computer, smart speaker, and notebook computer form the device group 200, and each electronic device 100 in the device group 200 can communicate with each other through an application server.

For another example, the electronic devices 100 may also form the device group 200 through short-distance communication connections such as Wi-Fi connections or Bluetooth connections. For example, users can add mobile phones, tablets, smart speakers, and laptops to the Wi-Fi network named "1234". Each electronic device 100 in the Wi-Fi network forms a local area network, and all the devices in the local area network form a device group 200.

Of course, the electronic devices 100 in the device group 200 can also be interconnected through a switching device (for example, a USB data cable or a Dock device), so as to realize the communication function between the electronic devices 100 in the device group 200. The implementation of this application The example does not make any restrictions on this.

In the embodiment of the present application, each electronic device 100 in the device group 200 may be classified in advance.

Exemplarily, the electronic device 100 that is connected to an external power source and has a certain computing capability may be referred to as a class A device. For example, Class A devices may include TVs, routers, desktop computers, speakers, and so on. This type of equipment can use an external power supply to obtain power through plugs, data cables, etc. during work. Therefore, Class A equipment can always be in a standby state after being connected to an external power supply. Users generally do not make special requirements for the power consumption of Class A equipment.

Exemplarily, the electronic device 100 that uses a battery and has a certain computing capability may be referred to as a type B device. For example, Class B devices can include mobile phones, tablets, laptops, and so on. This type of equipment needs to use a battery to power the equipment itself when it is working. Taking a mobile phone as an example of a Class B device, the mobile phone can enter the standby state after the screen is off. When the mobile phone needs to interact with other electronic devices, it needs to wake up the mobile phone's processor (such as CPU) and related communication modules (such as Wi-Fi chip). When the processor or communication module wakes up more frequently, it will increase the power consumption of the mobile phone and shorten the standby time. Therefore, when users use Class B equipment, they generally hope that the power consumption of Class B equipment is as small as possible.

Exemplarily, the electronic device 100 with weak computing capability may be referred to as a Class C device. For example, Class C devices may include air conditioners, refrigerators, smart light bulbs, wearable devices (such as smart watches, smart bracelets, smart glasses, etc.). Due to the weak computing power of Class C devices, such devices are generally used as controlled devices to be bound to corresponding main control devices such as Class A devices, Class B devices, or servers. The user can control the corresponding Class C device through the main control device. The power consumption of the Class C device due to device interaction is generally small when it is working.

It should be noted that the above-mentioned type A equipment can also be referred to as the first type equipment, the B type equipment is referred to as the second type equipment, and the C equipment is referred to as the third type equipment; or, the B type equipment is referred to as the first type equipment. The first type of equipment, the C equipment is called the second type of equipment, that is, the A equipment, the B equipment, and the C equipment are three types of electronic equipment.

Before each electronic device 100 leaves the factory, a corresponding flag bit can be set in the configuration file of the electronic device 100 in advance to indicate the device type of the electronic device 100. In subsequent embodiments, the flag bit can be referred to as a device tag. For example, when the device label is 00, it means that the electronic device 100 is a class A device; when the device label is 01, it means that the electronic device 100 is a class B device; when the device label is 11, it means that the electronic device 100 is class C equipment. In this way, the electronic device 100 can learn its own device type by reading its own device tag in the working process. In addition, the electronic device 100 may also receive device tags sent by other devices, so as to learn the device types of other devices.

Alternatively, the device type of the electronic device 100 may also be dynamically changed. For example, when a mobile phone uses a battery to power itself, its device tag can be set as a Class B device. If it is detected that the mobile phone is connected to an external power source through the charger, the mobile phone can set its label as a Class A device. If it is detected that the battery level of the mobile phone is lower than the threshold or the mobile phone enters the low battery protection mode, the mobile phone can set its label as a Class C device. For another example, when the electronic device 100 needs to be updated, the corresponding firmware or patch update file may be obtained from the server, and the update file may also include the device type newly set for the electronic device 100. In this way, when the electronic device 100 obtains the update file for device update, it can update its own device label according to the newly set device type in the update file.

In the embodiment of the present application, each electronic device 100 in the device group 200 may store a device information list. The device information list includes device information of each electronic device 100. For example, the device information may include the device name, device type, device model, IP (internet protocol) address, MAC (media access control) address, services provided by the device, customized business information, etc. Exemplarily, the device information list stored in the electronic device A is shown in Table 1. Through the device information list, the electronic device A can query the specific name, type, service provided, and recent information of an electronic device in the device group 200. Device status such as wake-up time. In other words, each electronic device can learn the device status of each electronic device 100 in the device group 200 through the device information list stored by itself.

Table 1

In addition, each electronic device 100 in the device group 200 may periodically update its stored device information list. For example, each electronic device 100 in the device group 200 may periodically send a multicast containing its own device information to other electronic devices. After each electronic device receives the device information sent by other electronic devices, it can update the device status of the corresponding electronic device in its stored device information list. In this way, each electronic device can learn the latest device status of each electronic device 100 in the device group 200 through the device information list stored in itself.

Then, when multiple electronic devices 100 in the device group 200 need to work collaboratively, the electronic devices participating in the collaborative work can quickly query the device status of other electronic devices according to the recently updated device information list, and then according to the multiple electronic devices participating in the collaborative work. The equipment status of the electronic equipment quickly completes this collaborative task.

For example, when the user utters the wake-up word of "Xiaoyi Xiaoyi", speaker 1 detects that the user utters the wake-up word and can find out from Table 1 that mobile phone 1 also provides voice functions, and the last wake-up time of mobile phone 1 has been More than 24 hours. Similarly, after the mobile phone 1 detects that the user utters the wake-up word, it can be queried from Table 1 that the speaker 1 also provides a voice function, and the last wake-up time of the speaker 1 is 13:05:47. If the preset wake-up strategy is that the most recently awakened electronic device responds to the user's wake-up word first, then speaker 1 can determine that speaker 1 (ie itself) responds to the user's wake-up word this time according to the latest wake-up time of mobile phone 1. At the same time, the mobile phone 1 can also determine according to the recent wake-up time of the speaker 1 that the mobile phone 1 does not need to answer the wake-up word spoken by the user this time. Furthermore, the speaker 1 can turn on the corresponding voice function to answer the wake-up word "Xiaoyi Xiaoyi" spoken by the user, and the speaker 1 and the mobile phone 1 also end this collaborative work task.

It can be seen that since each electronic device 100 of the device group 200 stores the latest device status of other electronic devices, when multiple electronic devices need to complete a collaborative work task, each electronic device participating in the collaborative work can be based on The latest device information list can quickly query the device status of other electronic devices, and then quickly complete the collaborative task according to the device status of other electronic devices, which reduces the time consumption of multiple devices working together.

At the same time, since each electronic device can quickly query the device status of other electronic devices through the above device information list, the number of data interactions between electronic devices is reduced when multiple devices work together. For the above-mentioned Class B devices, The number of times that Class B devices are awakened from standby or performing data interactions is also reduced, thereby reducing the power consumption of Class B devices and extending the standby time of Class B devices.

Wherein, the method for updating the above device information list by the electronic device in the device group 200, and the specific working modes of the A device, the B device, and the C device in the device group 200 will be described in detail in the subsequent embodiments, so it will not be described here.

In the following, a method for information synchronization between multiple devices provided by an embodiment of the present application will be described in detail with reference to the accompanying drawings.

Exemplarily, when a user adds an electronic device to the above-mentioned device group 200, the electronic device may determine that its device type is specifically the above-mentioned type A device, type B device or type C device according to the device tag stored in itself, and further, The electronic device can enter different working modes to start working. For example, if the electronic device is a class A device, the electronic device can automatically enter the preset working mode A; if the electronic device is a class B device, the electronic device can automatically enter the preset working mode B; if the electronic device is C equipment, the electronic equipment can automatically enter the preset working mode C.

It should be noted that the above-mentioned working modes (for example, working mode A, working mode B, working mode C above and working mode B1, working mode B2, master working mode or slave working mode in the subsequent embodiments) are electronic devices A general term for a series of working steps and working mechanisms during work. Electronic equipment may not need to perform specific steps to enter a certain working mode during actual operation. Or, taking the electronic device as an example of a class A device, the preset working state variable can be set to 01 when the electronic device starts working, which is used to indicate that the current working mode of the electronic device is working mode A. At this time, the step in which the electronic device sets the above-mentioned working state variable to 01 can be regarded as a step in which the electronic device enters the working mode A.

Taking each electronic device in the Wi-Fi network of a user’s home to form the above device group 200 as an example, as shown in Figure 3, after the electronic device 1 joins the Wi-Fi network, it can be multicast through DNS (domain name system, domain name system) The first message is sent to each electronic device in the Wi-Fi network. The first message includes the network access time of the electronic device 1 and the device information. Wherein, the network access time of electronic device 1 refers to the time when electronic device 1 accesses the aforementioned Wi-Fi network. The device information of electronic device 1 may include the device name, device type, device model, IP address, MAC address, The status of the device such as the services provided by the device and the customized business information.

After each electronic device in the Wi-Fi network receives the first message sent by the newly added electronic device 1, it can send a second message to the electronic device 1 in response to the first message. The second message includes the network access time and device information of the electronic device that sent the second message. In this way, after the electronic device 1 joins the Wi-Fi network, it can receive the second message from each electronic device that has joined the Wi-Fi network. Exemplarily, after the electronic device 1 receives the second message from each electronic device in the Wi-Fi network that has joined the Wi-Fi network, it may form the device information list shown in Table 2. The electronic device 1 can query the recent specific device status of other electronic devices in the Wi-Fi network through the device information list. Of course, the device information list shown in Table 2 may also include the network access time and device information of the electronic device 1, which is not limited in the embodiment of the present application.

Table 2

After the electronic device 1 generates the above-mentioned device information list according to the second message sent by each electronic device in the Wi-Fi network, the electronic device 1 can determine which working mode it enters to start working according to its own device type. For example, if the device label in the electronic device 1 indicates that the electronic device 1 is a class A device (such as a speaker, smart TV, etc.), the electronic device 1 can enter the preset working mode A; if the device label in the electronic device 1 indicates electronic Device 1 is a Class B device (such as a mobile phone, a tablet computer, etc.), then the electronic device 1 can enter the preset working mode B; if the device label in the electronic device 1 indicates that the electronic device 1 is a Class C device (such as a wearable device, Smart bulb, etc.), the electronic device 1 can enter the preset working mode C.

In addition, the above-mentioned working mode B may also include working mode B1 and working mode B2. That is to say, when the electronic device 1 is a type B device, the electronic device 1 can choose one of the two working mechanisms of the working mode B1 and the working mode B2. For example, after the electronic device 1 determines that it is a Class B device, it can query whether there is a Class A device in the current Wi-Fi network through the above-mentioned device information list. If there is a class A device, the electronic device 1 can enter the working mode B1; if there is no class A device, the electronic device 1 can enter the working mode B2.

The following specifically introduces the working mode A of Class A equipment:

Generally, a class A device working in working mode A is mainly used to receive device information periodically sent by other devices in the Wi-Fi network, and then update the device information of the corresponding device in the device information list, so that the device information stored in the class A device The information of each device in the list is in the latest state. In addition, other devices in the Wi-Fi network can also obtain the latest device information list from Class A devices, so that each device in the Wi-Fi network can learn the latest device status of other devices.

Exemplarily, a class A device working in working mode A can wait for the class B device to actively report its device information, and when it reports the device information, it will issue the latest device information list to the class B device, thereby reducing the class B device’s slave status. The number of times that the standby state is awakened, to avoid the extra power consumption of Class B devices.

As shown in FIG. 4, after the electronic device 1 enters the working mode A, it can determine whether the electronic device 1 is currently the master device according to a preset master decision algorithm (ie, S401). If there is no Class A device in the Wi-Fi network before the electronic device 1 joins the Wi-Fi network, the electronic device 1 can determine itself as the master device after entering the working mode A. If there are one or more Class A devices in the Wi-Fi network before the electronic device 1 joins the Wi-Fi network, the electronic device 1 can negotiate with the one or more Class A devices after entering the working mode A The main device in the current Wi-Fi network.

For example, the foregoing main device decision-making algorithm may be: the Class A device with the earliest network access time is the main device. Then, after the electronic device 1 enters the working mode A, it can determine whether it is the earliest type A device connected to the network according to the network access time of each type A device recorded in Table 2 and its own network access time. If the electronic device 1 is the earliest type A device connected to the network, then the electronic device 1 can enter the master device working mode as the master device; if the electronic device 1 is not the earliest type A device connected to the network, the electronic device 1 can enter the slave device (slave) Slave working mode.

For another example, the aforementioned master device decision-making algorithm may also be: selecting a specific type of device as the master device. Exemplarily, the priority order between different types of devices in Class A devices can be preset. For example, the priority of the TV is greater than the priority of the router, and the priority of the router is greater than the priority of the smart speaker. Then, after the electronic device 1 enters the working mode A, it can determine whether it is the class A device with the highest priority according to the device type of each class A device recorded in Table 2 and its own device type. If the electronic device 1 is a class A device with the highest priority, then the electronic device 1 can enter the master working mode as the master device; if the electronic device 1 is not the class A device with the highest priority, then the electronic device 1 can enter the slave device as a slave device. Device working mode.

Of course, the above-mentioned main device decision algorithm may also be a decision algorithm such as a raft election algorithm. One or more main devices may be set in the Wi-Fi network, and the embodiment of the present application does not impose any limitation on this.

As shown in (a) of FIG. 12, the Class A device 1 in the Wi-Fi network is the only master device (master), and the master device is used to maintain the device information of all electronic devices in the Wi-Fi network. Other devices in the Wi-Fi network (for example, Class A device 2, Class A device 3, Class B device 1, Class B device 2, and Class C device 1) can be used as slave devices to establish with this master device Connect, and each slave device reports its own device information to the master device. In addition, each slave device can also obtain the latest device information list from the master device.

As shown in Figure 12(b), the Wi-Fi network includes Class A device 1, Class A device 2 and Class A device 3. Among them, Class A device 1, Class A device 2 and Class A device 3 are all Master (master). Then, the class A device 1 can establish a connection with the class B device 1 and the class B device 2 respectively, so as to obtain the device information of the class B device 1 and the class B device 2. At this time, the type B device 1 and the type B device 2 are slaves of the type A device 1. The Class A device 2 can establish a connection with the Class C device 1 and the Class B device 3, respectively, so as to obtain the device information of the Class C device 1 and the Class B device 3. At this time, the C-type device 1 and the B-type device 3 are slaves of the A-type device 1.

In addition, the class A device 1, the class A device 2, and the class A device 3 as the master device can be connected to each other. In this way, Class A devices 1 to A device 3 can synchronize the received device information reported by each electronic device with each other, so that each main device can obtain the latest device information of all electronic devices in the Wi-Fi network. Form the latest equipment information list.

As still shown in FIG. 4, when the electronic device 1 enters the main device working mode, the electronic device 1 can send a message indicating the main device to other electronic devices in the Wi-Fi network through DNS multicast (ie S402) , The field used to indicate the master device in the message may include the identification of the electronic device 1. After receiving the message, other electronic devices can determine that the main device in the current Wi-Fi network is electronic device 1.

For example, after the electronic device 2 receives the update message from the electronic device 1, since the electronic device 2 also stores a device information list similar to the above-mentioned Table 1 or Table 2, the electronic device 2 can be in the stored device information list Mark the electronic device 1 as the main device. Subsequently, the electronic device 2 can be used as a slave device to establish a connection with the electronic device 1, and periodically report its own device information to the electronic device 1 (ie, the master device).

As still shown in FIG. 4, the electronic device 1 can update the device information of the corresponding device in its device information list after receiving device information (ie S403) from other electronic devices (ie slave devices) in the master device working mode. The device information list stored in the electronic device 1 is kept in the latest state. In addition, after the electronic device 1 receives the device information sent from the slave device, it can also send the latest device information list to the slave device (ie S404). After the slave device receives the device information list sent by the master device, it can store the stored device information list. The device information list of is deleted, so that the device information list stored in each slave device is synchronized with the device information list stored in the electronic device 1, and they are all in the latest state.

As still shown in FIG. 4, if the electronic device 1 enters the slave device working mode, the electronic device 1 can start the preset timer T1 (ie S405). When the timer T1 expires, the electronic device 1 can act as a slave device to send its latest device information to the current master device (ie S406). In this way, the master device can update the device information of the corresponding electronic device 1 in its device information list. In addition, the master device can send the latest device information list to the electronic device 1 (ie S407), so that the electronic device 1 can learn the latest device status of other electronic devices in the Wi-Fi network through the device information list.

In some embodiments, when the electronic device 1 serves as a slave device to send device information to the master device, if it fails to send device information to the master device multiple times in succession, it means that the master device may have been replaced or offline at this time, then the electronic device Device 1 can re-determine the main device in the current Wi-Fi network and send its own device information to the new main device.

In some embodiments, after the electronic device 1 enters the slave device working mode, if it receives device information from other slave devices, it means that the slave device may incorrectly determine the electronic device 1 as the master device, then the electronic device 1 can send the current master device identification to the slave device to inform the slave device of the current correct master device.

In addition, regardless of whether the electronic device 1 enters the master device working mode or the slave device working mode, if the electronic device 1 receives a message that a new device joins, the device exits, or the master device is updated in the Wi-Fi network, the electronic device 1 can re-determine the current The master device in the Wi-Fi network determines that the electronic device 1 needs to enter the master device working mode or the slave device working mode at this time.

Exemplarily, when the electronic device 1 is the master device, if it receives a message that the electronic device 2 exits the Wi-Fi network, the electronic device 1 can determine that the new master device is the electronic device at this time according to the preset master device decision algorithm 3. Then, the electronic device 1 can enter the above-mentioned slave device working mode and disconnect the established connection with other electronic devices. For example, the connection can be a network connection at the L3 layer. In addition, the electronic device 1 can send a message to other Class A devices to notify the other Class A devices that the new master device is the electronic device 3. At this time, the electronic device 1 may not send a message to the Class B device to notify the new master device. When the class B device actively sends its own device information to the electronic device 1, the electronic device 1 can notify the class B device of the new master device, so as to reduce the power consumption of the class B device being actively awakened by the class A device.

In a specific implementation manner, as shown in FIG. 13, after the electronic device 1 enters the working mode A, it can query whether there is a class A device that has an earlier network access time (that is, S1301). If there is no Class A device earlier than its own network access time, the electronic device 1 can enter the master working mode; if there is a Class A device earlier than its own network access time, then the electronic device 1 can enter the slave device (slave) working mode.

As shown in Figure 13, after the electronic device 1 enters the master working mode, the electronic device 1 can be used as the master device to send DNS broadcasts to other electronic devices in the Wi-Fi network through DNS multicast (ie mDNS) to inform other electronic devices. The main device of the device is updated to electronic device 1. At the same time, the electronic device 1 can wait for other electronic devices in the Wi-Fi network to establish an L3 network connection with itself (ie S1302). After the electronic device 1 monitors the connection request from the slave device, it can establish an L3 layer network connection with the corresponding slave device. After the electronic device 1 receives the device information sent from the device through the established network connection, it can update the device information of the corresponding device in its device information list (ie S1303), so that the device information list is in the latest state. In addition, the electronic device 1 may save the updated device information list in a preset home network device information database.

In addition, after the electronic device 1 enters the master working mode, if it receives DNS multicast from other devices, or receives a message that the slave device disconnects from the network (ie S1304), the electronic device 1 can re-determine itself Whether it is still the main device in the current Wi-Fi network (ie S1305). For example, if the electronic device 1 determines that there are other Class A devices whose access time is earlier than its own network access time, then the electronic device 1 can determine the Class A device with the earliest access time as the latest master device in the Wi-Fi network (i.e. S1306 ). Then, the electronic device 1 can send a message to other Class A devices, thereby notifying the other Class A devices of the new master device (ie S1307). In addition, the electronic device 1 can disconnect the network connection established with the slave device and enter the slave working mode.

As shown in FIG. 13, after the electronic device 1 enters the slave working mode, the electronic device 1 can establish an L3 network connection with the determined master device (ie S1308). Furthermore, the electronic device 1 can start a timer (for example, the timer T1). When the timer T1 expires, the electronic device 1 can act as a slave device to send its latest device information to the current master device (ie S1309). If sending device information to the main device for multiple times (for example, N0 times) times out, it means that the main device may have been replaced or offline at this time. Then, the electronic device 1 can re-determine the main device (ie, the main device in the current Wi-Fi network). S1310).

In addition, after the electronic device 1 enters the slave working mode, if it receives DNS multicast from other devices, or receives a message that the slave device disconnects from the network (ie S1311), the electronic device 1 can re-determine the current The main device in the Wi-Fi network. If the main device in the current Wi-Fi network changes, the electronic device 1 can disconnect the network connection with the old main device and establish a network connection with the new main device (ie S1312).

The following specifically introduces the working mode B1 of Class B equipment:

Exemplarily, a Class B device working in the working mode B1 can periodically send its own device information to the main device in the Class A device, and at the same time obtain the latest device information list from the main device, so as to be based on each device in the device information list. The device information in the Wi-Fi network completes the collaborative work task with other devices in the Wi-Fi network.

Exemplarily, as shown in FIG. 5, after the electronic device 1 enters the working mode B1, the electronic device 1 can determine the main device in the current Wi-Fi network and establish a connection with the main device (ie S501).

For example, the electronic device 1 can query whether there is a Class A device marked as the main device in the device information list stored in itself. If a Class A device marked as the main device is queried, the electronic device 1 can establish a connection with the main device. For example, the connection can be a network connection at the L3 layer. Among them, the network connection of the L3 layer can specifically be a TCP (transmission control protocol) connection or a UDP (user datagram protocol, user datagram protocol)-based network connection, such as UDP-based CoAP (constrained application protocol, restricted Application protocol) connection, the embodiment of this application does not impose any restriction on this.

For another example, if the electronic device 1 receives an update message of the master device sent by other devices, the electronic device 1 can establish a connection with the updated master device. For another example, the electronic device 1 may also determine any type A device in the Wi-Fi network as the master device. When the electronic device 1 actively sends its own device information to the determined main device, if the Class A device that receives the device information sent by the electronic device 1 is not the real main device, the Class A device can notify the Class B device at this time A new master device to reduce the power consumption of Class B devices being actively awakened by Class A devices.

Still as shown in FIG. 5, after determining the main device in the current Wi-Fi network, the electronic device 1 can start the preset timer T2 (ie S502). When the timer T2 expires, the electronic device 1 can act as a slave device to send its own latest device information to the determined master device (ie S503). In this way, the master device can update the device information of the corresponding electronic device 1 in its device information list. In addition, the master device can send the latest device information list to the electronic device 1 (ie S504), so that the electronic device 1 can learn the latest device status of each electronic device in the Wi-Fi network through the device information list.

Exemplarily, for a type B device with a faster update of device information, a shorter timing duration of the timer T2 can be set; for a type B device with a slower update of device information, a longer timing duration of the timer T2 can be set. In this way, it is possible to reduce the number of wake-ups of the type B equipment as much as possible while ensuring that the device information of the type B equipment is updated in time, thereby reducing the power consumption of the type B equipment.

Or, because Class B devices (such as mobile phones, tablet computers) regularly send heartbeat messages to the PUSH message server. Then, the timing duration of the timer T2 can be set to be synchronized with the period of the heartbeat message sent by the Class B device. In this way, each time a Class B device is awakened and sends a heartbeat message to the PUSH message server, it can also send its own latest device information to the master device, thereby reducing the number of additional wake-ups of Class B devices and reducing the power consumption of Class B devices . Among them, the timer for the type B device to send a heartbeat message to the PUSH message server and the timer for the type B device to send its own latest device information to the master device may be one.

It can be seen that in working mode B1, Class B devices rarely receive messages from other devices to wake up Class B devices, and in working mode B1, Class B devices will actively report device information to the master device and synchronize periodically. Device information list, which makes the number of times that Class B devices are awakened relatively stable, so that the power consumption of Class B devices is more stable and controllable, and will not increase with the increase in the number of devices in the Wi-Fi network.

In addition, if a Class B device fails to send device information to the main device multiple times in working mode B1, it means that the main device may have been replaced or offline at this time. Then, the electronic device 1 can re-determine the current Wi-Fi network The master device, and send its own device information to the new master device. If there is no Class A device in the current Wi-Fi network, the electronic device 1 can enter the working mode B2.

In a specific implementation, as shown in FIG. 14, after the electronic device 1 enters the working mode B1, the electronic device 1 can determine a master device from the Class A devices of the Wi-Fi network, and establish an L3 with the master device. Layer network connection (ie S1401). Of course, if the electronic device 1 receives the update message of the master device, the electronic device 1 can disconnect the network connection with the current master device and establish an L3 network connection with the new master device (ie S1402). After determining the master device, the electronic device 1 can start a preset timer (for example, timer T2). When the timer T2 expires, the electronic device 1 can act as a slave device to send its latest device information to the determined master device (ie S1403). At the same time, the electronic device 1 can synchronize the latest device information list from the home network device information database of the master device (S1404).

If the network connection between the electronic device 1 and the main device times out (ie S1405), it means that the main device may have been replaced or offline at this time. Then, the electronic device 1 can re-determine the current Wi-Fi network in the Class A device The main device (that is, back to S1401), establish a network connection with the new main device. If there is no Class A device in the current Wi-Fi network, the electronic device 1 can enter the working mode B2.

The following specifically introduces the working mode B2 of Class B equipment:

Since there is no class A device in the working mode B2, there is no master device in the working mode B2. Multiple Class B devices entering working mode B2 can form a ring network according to a preset networking algorithm.

As shown in Figure 6, Class B devices 1 to B devices 3 form a ring network, and each Class B device can control one or more Class C devices. The Class B equipment on each node in the ring network can periodically receive the updated device information list sent by the Class B equipment of the previous node, and the Class B equipment of each node can periodically receive the Class B equipment of the next node. Send the updated device information list.

For example, class B device 1 can generate device information list 1 based on the device information of class B device 1 and the device information reported by class C device 1, and send device information list 1 to class B device when the preset timer T3 expires 2. After receiving the device information list 1, the class B device 2 can add its own device information to the device information list 1 to form the device information list 2. When the preset timer T4 expires, the class B device 2 can send the device information list 2 to the class B device 3. After receiving the device information list 2, the class B device 3 can add its own device information and the device information reported by the class C device 2 to the device information list 2 to form the device information list 3. Similarly, when the preset timer T5 expires, the class B device 3 can send the device information list 3 to the class B device 1. In this way, the Class B device 1 to the Class B device 3 can circulate the above method to periodically update the device information list stored in themselves, so as to learn the latest device status of each device in the Wi-Fi network.

It can be seen that in working mode B2, each type B device only needs to be awakened by the type B device of the previous node in one cycle to obtain the latest device information list. In this way, the number of wake-ups for type B devices will be greatly reduced, and the power consumption of type B devices will be reduced accordingly.

In some embodiments, the timing duration of the timer T3, the timer T4, and the timer T5 may be the same or different.

In other embodiments, only one timer T0 may be set in one node of the above-mentioned ring network. For example, the timer T0 can be set in the Class B device 1. When the timer T0 expires, the class B device 1 can send the latest device information list to the class B device 2. After class B device 2 receives the device information list sent by class B device 1, it can update the device information list and send the updated device information list to the next node (ie, class B device 3). Similarly, after receiving the device information list sent by the B device 2, the class B device 3 can update the device information list, and send the updated device information list to the next node (ie, the class B device 1). Subsequent, Class B device 1 to Class B device 3 can periodically update the device information list stored by themselves through the above-mentioned method, so as to learn the latest device status of each device in the Wi-Fi network.

Exemplarily, as shown in FIG. 7, after the electronic device 1 enters the working mode B2, the electronic device 1 can join the above-mentioned ring network as a new node according to the preset networking algorithm (i.e., S701). For example, the electronic device 1 can be plugged into the above-mentioned ring network as a Class B device 4. At this time, the original connection between the class B device 3 and the class B device 1 can be disconnected, and the newly added electronic device 1 can establish a connection with the class B device 3 and the class B device 1 respectively. Class B device 3 is the previous node of electronic device 1, and class B device 1 is the next node of electronic device 1.

As still shown in FIG. 7, after the electronic device 1 joins the above-mentioned ring network, it can receive the device information list sent by the previous node (ie, the type B device 3) (ie, S702). Furthermore, the electronic device 1 can start a preset timer T6 (ie S703). When the timer T6 expires, the electronic device 1 can update the above-mentioned device information list and send the latest device information list to the next node: Class B device 1 (ie S704).

In some embodiments, if the electronic device 1 fails to send the device information list to the next node multiple times in succession, it means that the next node of the electronic device 1 may be offline, and then the electronic device 1 can continue to the next node (I.e. Class B device 2) Send a list of device information.

In some embodiments, after the electronic device 1 enters the working mode B2, if it receives a message that a new device joins in the Wi-Fi network, the electronic device 1 can determine whether the new device is Class A according to the device information sent by the new device equipment. If the newly added device is not a Class A device, the electronic device 1 can re-determine its position in the ring network according to the preset networking algorithm, that is, determine the previous position of the electronic device 1 in the ring network after the new device is added. Which type B device the node and the next node are specifically. Furthermore, the electronic device 1 can periodically receive the device information list sent by the previous node according to the above method, and periodically send the latest device information list to the next node. Correspondingly, if the newly added device this time is a class A device, the electronic device 1 can switch from the working mode B2 to the above-mentioned working mode B1.

In a specific implementation, as shown in FIG. 15, after the electronic device 1 enters the working mode B2, the electronic device 1 can join the aforementioned ring network as a new node according to a preset networking algorithm (ie S1501). Furthermore, after the electronic device 1 receives the device information list (ie S1502) sent by the previous node, the device information list may also be called home device information data, it can update the device information list (ie S1503) and start the preset timing Device (e.g. timer T6). When the timer T6 expires, the electronic device 1 can send the latest device information list to the next node (ie S1504). If the network connection between the electronic device 1 and the next node times out, the electronic device 1 may try to establish a network connection with the next node of the next node (ie S1505).

In addition, after the electronic device 1 enters the working mode B2, if it receives a network access message of a new device in the Wi-Fi network (ie S1506), the electronic device 1 can query whether the new device is a class A device. If the new device is not a Class A device, the electronic device 1 can determine whether it is the previous node of the new device according to a preset networking algorithm (ie S1507). If it is the previous node, the electronic device 1 can disconnect the network connection between the electronic device 1 and the next node in the original ring network, and establish a network connection with the new device (ie S1508); otherwise, the electronic device 1 can continue Keep network connection with the previous node. Correspondingly, if the new device is a class A device, the electronic device 1 can enter the above-mentioned B1 working mode.

The following specifically introduces the working mode C of class C equipment:

Class C devices are generally bound to the corresponding master control device as a controlled device. For example, the main control device of the C-type device may be the above-mentioned Class A device or the B-type device, and the main control device of the C-type device may also be a server. For example, the main control device of a wearable device is generally a class B device such as a mobile phone, the main control device of a smart light bulb can be a class A device such as a router, and the main control device of a smart meter can be a server of a power company.

Due to the limited computing capabilities and storage capabilities of Class C devices, when the electronic device 1 enters working mode C, it can periodically report its own device information to the corresponding master control device without obtaining and saving the current device information list.

When there are Class A devices in the Wi-Fi network, there are one or more master devices in the Wi-Fi network. Illustratively, as shown in FIG. 8, the Class A device 1 can be used as the master device to enter the master in the above working mode A. Device working mode, Class A device 2 can be used as a slave device to enter the working mode of the slave device in the above working mode A. In addition, the type B device 1 and the type B device 2 in the Wi-Fi network can also be used as slave devices to enter the above-mentioned working mode B1.

Among them, the class B device 1 is the main control device of the class C device 1, the class B device 2 is the main control device of the class C device 2, and the main control device of the class C device 3 is the server. Then, the class C device 1 can report its own device information to the class B device 1 according to cycle 1. The class B device 1 can report the device information of the class C device 1 to the main device when reporting the device information of the class B device 1 to the main device (ie, the class A device 1). Similarly, the class C device 2 can report its own device information to the class B device 2 according to cycle 2. The class B device 2 may report the device information of the class C device 2 to the main device when reporting the device information of the class B device 2 to the main device. In addition, the class C device 3 can periodically report its own device information to the server, and the main device (ie, the class A device 1) can periodically obtain the device information of the class C device 3 from the server.

Then, the main device (ie, the Class A device 1) can periodically obtain the device information of all devices in the Wi-Fi network and form the latest device information list. When other devices in the Wi-Fi network report their own device information to the main device, they can also obtain the latest device information list from the main device. In this way, all devices in the Wi-Fi network can save a list of the latest device information, and each device can learn the latest device status of other devices according to the device information list, so as to quickly participate in the subsequent and complete the multi-device information Of collaborative work tasks.

When there is no Class A device in the Wi-Fi network, there is no main device in the Wi-Fi network. Illustratively, as shown in FIG. 9, Class B devices 1 to B devices 3 can form a ring network. Class B equipment 1 to Class B equipment 3 can all enter the above-mentioned working mode B2. Among them, the class B device 1 is the main control device of the class C device 1, the class B device 2 is the main control device of the class C device 2, and the main control device of the class C device 3 is the server.

Then, the class C device 1 can report its own device information to the class B device 1 according to cycle 1. The class B device 1 can add its own device information and the device information of the class C device 1 to the device information list when sending the device information list to the next node (ie, the class B device 2) according to the above-mentioned working mode B2. Similarly, the class C device 2 can report its own device information to the class B device 2 according to cycle 2. The class B device 2 can add its own device information and the device information of the class C device 2 to the device information list when sending the device information list to the next node (ie, the class B device 3) according to the above-mentioned working mode B2. In addition, the class C device 3 can periodically report its own device information to the server. A certain class B device in the ring network can obtain the device information of the class C device 3 from the server, and update the device information of the class C device 3 In the device information list.

For example, you can set to obtain the device information of the C-type device 3 from the server when a certain B-type device in the ring network is awakened, so as to prevent the B-type device from interacting with the server after being awakened in the standby state, and reduce the B-type device The additional power consumption caused by querying the device information of Class C devices.

It can be seen that regardless of whether there are Class A devices in the Wi-Fi network, all types of devices in the Wi-Fi network can obtain a copy of the latest Device information list. Each device can learn the latest device status of other devices according to the device information list, so that it can quickly participate in and complete the collaborative work tasks between multiple devices.

In the above embodiment, the electronic device 1 enters the working mode A, the working mode B or the working mode C when it joins the above-mentioned Wi-Fi network as an example. It is understandable that each electronic device in the Wi-Fi network can enter the working mode corresponding to its own device type and start working according to the above method.

Exemplarily, the schematic diagram of the above-mentioned Wi-Fi network architecture may be as shown in FIG. 10. The Wi-Fi network includes 3 class A devices (namely, TV 1001, speaker 1002, and router 1003), and 2 class B devices (namely Mobile phone 1004 and tablet PC 1005) and 3 Class C devices (that is, wearable device 1006, smart light bulb 1007, and smart air conditioner 1008).

Among them, the TV 1001 can be used as the main device in the Wi-Fi network to enter the main device working mode. Other Class A devices in the Wi-Fi network can be used as slave devices of the TV 1001 to enter the slave device working mode, and Class B devices in the Wi-Fi network can also be used as slave devices of the TV 1001 to enter the working mode B1.

For example, the speaker 1002 and the router 1003 can actively report their device information to the TV 1001 every 30s in a period of 30s, and synchronize the latest device information list from the TV 1001. The mobile phone 1004 and the tablet computer 1005 can actively report their device information to the TV 1001 every time a heartbeat message is sent to the PUSH server, and synchronize the latest device information list from the TV 1001.

In addition, the main control device of the wearable device 1006 in Class C devices is a mobile phone 1004, the main control device of the smart light bulb 1007 is the TV 1001, and the main control device of the smart air conditioner 1008 is the server 1009. Exemplarily, the wearable device 1006 may periodically report its own device information to the mobile phone 1004, and the mobile phone 1004 may report the device information of the wearable device 1006 when reporting its own device information to the TV 1001. The smart bulb 1007 can periodically report its own device information to the TV 1001. The smart air conditioner 1008 can periodically report its own device information to the server 1009. The TV 1001 can take 30s as a period, and actively obtain the device information of the smart air conditioner 1008 from the server 1009 every 30s.

In this way, the TV 1001 can obtain the latest device information of each electronic device in the Wi-Fi network, and form the latest device information list. In addition, the TV 1001 can synchronize the latest device information list to other electronic devices in the Wi-Fi network, so that each electronic device in the Wi-Fi network can learn the latest device status of other electronic devices according to the device information list.

Exemplarily, the schematic diagram of the architecture of the above Wi-Fi network may be as shown in FIG. 11, and the Wi-Fi network includes 3 class B devices (ie, mobile phone 1101, mobile phone 1102, and tablet computer 1103) and 3 class C devices ( That is, the wearable device 1104, the smart bulb 1105, and the smart air conditioner 1106).

It can be seen that the above-mentioned Wi-Fi network does not include Class A devices, then the mobile phone 1101, the mobile phone 1102, and the tablet computer 1103 can enter the above-mentioned working mode B2 to form a ring network. Among them, the mobile phone 1101 is the main control device of the wearable device 1104, the mobile phone 1102 is the main control device of the smart light bulb 1105, and the main control device of the smart air conditioner 1106 is the server 1107.

Exemplarily, the wearable device 1104 may periodically report its own device information to the mobile phone 1101. The mobile phone 1101 can carry its own device information and the device information of the wearable device 1104 in the device information list when sending the device information list to the next node (ie, the mobile phone 1102) according to the above-mentioned working mode B2.

Similarly, the smart bulb 1105 can report its device information to the mobile phone 1102 periodically. The mobile phone 1102 can carry its own device information and the device information of the smart bulb 1105 in the device information list when sending the device information list to the next node (ie, the tablet 1103) according to the above-mentioned working mode B2.

In addition, the smart air conditioner 1106 may periodically report its own device information to the server 1107. The mobile phone 1102 in the Wi-Fi network can actively obtain the device information of the smart air conditioner 1106 from the server 1107 when sending a heartbeat message to the PUSH server, and update the device information of the smart air conditioner 1106 in the device information list.

In this way, the B-type devices in the ring network can obtain the latest device information list through regular synchronization, so that the latest device status of each electronic device in the Wi-Fi network can be obtained according to the device information list.

Then, when multiple electronic devices are required to work collaboratively in the aforementioned Wi-Fi network, the electronic devices participating in the collaborative work can quickly query the device status of other electronic devices based on the recently updated device information list, and then based on the number of electronic devices participating in the collaborative work. The device status of each electronic device quickly completes this collaborative task.

Taking the Wi-Fi network shown in Figure 10 as an example, when the user utters the wake-up word of "Xiaoyi Xiaoyi", the TV 1001, speaker 1002, mobile phone 1004, and tablet computer 1005 in the Wi-Fi network can all detect this Wake word. Assuming that the preset wake-up strategy is that the most recently awakened electronic device responds to the user's wake-up word first, then, since the TV 1001, speaker 1002, mobile phone 1004, and tablet 1005 all store the latest device information list, the TV 1001 , Speaker 1002, mobile phone 1004, and tablet computer 1005 can query the latest awakening time of each electronic device in the Wi-Fi network that supports the voice wake-up function in the device information list stored by itself, and then determine the specific electronic device that responded to the user this time. equipment.

Taking the last awakened electronic device as an example of speaker 1002, speaker 1002 determines that it is the most recently awakened electronic device among TV 1001, speaker 1002, mobile phone 1004, and tablet 1005, and can turn on the corresponding voice function to answer the user’s comment. The awakening word "Xiaoyi Xiaoyi" came out. At this time, the TV 1001, the mobile phone 1004, and the tablet computer 1005 do not need to respond to the wake-up words spoken by the user, nor do they need to interact with the speaker 1002 for data.

It can be seen that since each electronic device in the Wi-Fi network stores the latest device status of other electronic devices, when multiple electronic devices need to complete a collaborative work task, each electronic device participating in the collaborative work can The device status of other electronic devices can be quickly queried according to the latest device information list, and then the collaborative task can be quickly completed according to the device status of other electronic devices, which reduces the time consumption of multiple devices working together.
