detailed description

In order to make the purposes, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments It is a part of the embodiments of the present application, but not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present application.

FIG. 1 is a schematic diagram of an application scenario provided by an embodiment of the present application. As shown in FIG. 1 , the illustrated application scenario is described by taking a local area network formed in a home as an example. In Figure 1, the mobile phone is used as a hotspot device, and devices such as refrigerators, TVs, air conditioners, and desk lamps are connected to the hotspot established by the mobile phone to access the network formed by the mobile phone. For the local area network shown in Figure 1, devices such as refrigerators, TVs, air conditioners, and desk lamps need to upload working data to the cloud server through mobile phones to perform statistics and management on the operation information of each device in the local area network. Among them, refrigerators, TVs, air conditioners, desk lamps and other devices need to be in the wake-up state when uploading working data to the cloud server, that is, each device is in the wake-up state when it needs to upload data, and returns to the sleep state after uploading data. Moreover, every time a device uploads working data to the cloud server through a mobile phone, the device needs to wake up the mobile phone, and then establish a communication connection with the mobile phone. When no device uploads data through the mobile phone, the mobile phone returns to the sleep state, thereby reducing the internal power of the local area network. consumption.

In the related art, the clocks of refrigerators, TVs, air conditioners, desk lamps and other devices are independent of each other, and there is no unified time reference, so the clocks of each device are not synchronized. Each device has an independent wake-up time period. This causes refrigerators, TVs, air conditioners, desk lamps and other devices to upload working data to the cloud server through intermediate devices in the local area network according to their respective wake-up time periods. Phones are frequently woken up, increasing power consumption.

And, when a device, such as a TV, is uploading work data through the mobile phone, if other devices, such as the projector, reach a wake-up time period and need to wake up to upload the work data, the projector starts to establish a connection with the mobile phone, but at this time , the phone is being occupied by another device, making the projector unable to use the phone. Therefore, in order not to increase the power consumption, the projector returns to the sleep state, and then wakes up every preset time to try to establish a connection with the mobile phone until the upload of the work data is completed. However, the device frequently switches between wake-up and sleep, and attempts to establish a connection with the mobile phone every time it is in the wake-up state, which also increases the overall power consumption of the local area network. In addition, when a device frequently switches between wake-up and sleep because the mobile phone is occupied by other devices, it will also cause other devices to fail to upload work data normally when the wake-up time period arrives, thus frequently switching between wake-up and sleep. It also increases the overall power consumption of the LAN.

Moreover, if the devices in the local area network cannot upload the work data normally when the wake-up time period arrives, the work data will not be uploaded in time, which will affect the statistics and management of the device operation information, which is not conducive to the centralized management of each device in the local area network. .

Therefore, in order to solve at least one problem existing in the related art, this application proposes that the WiFi6 protocol supports the target wakeup time (Target Wakeup Time, TWT) function and the clock synchronization (WLAN TimeSync) function. Wake-up time periods can be coordinated as needed. In addition, when the devices in the local area network access the local area network, they all need to access the hotspot of the intermediate device to connect to the local area network. For example, the refrigerator, TV, air conditioner, desk lamp and other devices in Figure 1 are connected to the hotspot turned on by the mobile phone to enter the local area network. Therefore, the running clock of the intermediate device can be synchronized to the devices connected to the network of the intermediate device. In this way, the running clocks of the devices in the local area network can be synchronized, and the problem that the clocks of the devices in the local area network are not synchronized can be solved. In addition, through the intermediate device, the intermediate device is also referred to as the master clock device in this application, and the other devices connected to the master clock device network are referred to in this application as the wake-up device. The wake-up devices in each group have the same wake-up time period, so that the wake-up devices in each group use the master clock device to upload working data in an orderly manner, avoiding frequent wake-up of the master clock device and frequent wake-up and sleep of the wake-up device. switching, reducing the overall power consumption of the LAN. In addition, the group management of the wake-up devices also improves the unified management of the wake-up devices and improves the overall intelligence of the local area network.

FIG. 2 is a flowchart of a device management method in the Internet of Things provided by an embodiment of the present application. The execution subject of the embodiment of the present application is the first device, that is, the master clock device, wherein the master clock device is a device that can open a hotspot, wherein the master clock device can be used as an independent device to establish a hotspot, for example, a mobile phone, or other A hotspot can be established together with the devices. For example, a portable wifi can be plugged into a USB interface of a desktop computer to establish a hotspot, which is not limited in this application. As shown in FIG. 2, the method of the embodiment of the present application includes:

S201. The first device sends clock synchronization information to a second device connected to the first network, so that the second device is synchronized with the running clock of the first device according to the clock synchronization information.

The access point of the first network is the first device.

In this embodiment, when the second device (that is, the wake-up device), such as a refrigerator, a TV, an air conditioner, and a desk lamp in FIG. 1 , is connected to a hotspot established by the master clock device, and is connected to the local area network, the master clock device, such as FIG. The mobile phone in 1 generates clock synchronization information, and encapsulates the clock synchronization information into a time synchronization data packet and sends it to the wake-up device. The clock synchronization information includes the time point when the master clock device sends the time synchronization data packet, and the time synchronization data packet will record the transmission duration during the transmission process.

After the wake-up device receives the time synchronization data packet, it decompresses the time synchronization data packet to obtain the clock synchronization information and the transmission duration. According to the time point when the master clock device sends the time synchronization data packet and the transmission duration recorded in the clock synchronization information, the calculation is obtained. Wake up the running clock of the master clock when the device receives the time synchronization data packet, and adjust its own running clock so that the adjusted running clock is synchronized with the running clock of the master clock device. Among them, in the local area network, since the operation clock of each wake-up device connected to the master clock device is synchronized with the operation clock of the master clock device, the operation clocks of all devices in the local area network are synchronized.

S202. The first device divides the second device into a target device group, where the target device group includes one or more second devices.

In this embodiment, for example, when the wake-up device is connected to the network of the master clock device, if the target device group can be divided, the wake-up device is divided into the target device group. At this time, the target device group includes at least two a wake-up device. Or, when the wake-up device is connected to the network of the master clock device, there is no target device group matching the wake-up device. In this case, a new device group is created. The newly created device group only includes the wake-up device. When a new wake-up device is connected to the network of the master clock device, if it matches the newly created device group, the new wake-up device will be divided into the newly created device. in the device group.

For another example, when the number of wake-up devices connected to the network of the master clock device reaches a preset number, the master clock device groups the plurality of wake-up devices, and divides each wake-up device into a matching target device group.

S203 , the wake-up time period of the first device to the target device group, so that each second device in the target device group uploads data through the first device when the wake-up time period arrives.

In this embodiment, the master clock device configures and manages the wake-up time period for the wake-up devices in each device group. When a wake-up device is divided into a new device group, the master clock device sends the wake-up time to the device group. period, so as to send the wake-up time period of the device group to the wake-up device when a wake-up device is divided into the device group. Moreover, if there are other wake-up devices that are divided into the device group, the master clock device can directly configure the wake-up time period of the device group to the wake-up device, so that the wake-up devices in the same device group have the same wake-up time period. In this way, for the wake-up devices in the same device group, since they have the same wake-up time period, the wake-up devices in the same device group will switch from the sleep state to the wake-up state at the same time to upload working data.

For the wake-up devices in the same device group, when uploading work data at the same time, one of the wake-up devices wakes the master clock device from the sleep state to the wake-up state and then uploads the work data. After the wake-up device completes the work data upload, the other A wake-up device can directly establish a connection with the master clock device, and use the master clock device to upload working data without waking up the master clock device again, reducing the number of times the master clock device is woken up.

Moreover, when the wake-up devices of the same device group upload working data at the same time, the order in which each wake-up device uploads the work data through the master clock device can be coordinated uniformly. For example, each wake-up device uses the master clock device in the default order, or The master clock device controls the upload sequence of each wake-up device to avoid the problem of multiple wake-up devices occupying the master clock device at the same time, thereby avoiding the problem that the wake-up device frequently switches between the sleep state and the wake-up state.

In this embodiment, the first device sends clock synchronization information to the second device connected to the first device network, so that the running clock of the second device is synchronized with the running clock of the first device. Then, the first device divides the second device into the target device group, and sends the wake-up time period to the target device group. In this way, each second device in the target device group has the same wake-up time period, so that the first device only needs to be woken up once when the wake-up time period arrives, reducing the number of times the first device is woken up and reducing the overall power consumption of the local area network. In addition, for the wake-up devices in the same device group, the order of uploading work data through the first device can be managed. Even if these wake-up devices wake up at the same time and upload work data through the first device, multiple wake-up devices can be avoided at the same time. The first device is occupied, thereby avoiding the frequent switching between the sleep state and the wake-up state due to the need to upload working data of the wake-up device, and also reduces the overall power consumption of the local area network. In addition, the wake-up devices in the same device group upload the work data in an orderly manner, which can also avoid the loss of the work data and the untimely upload.

FIG. 3 is a flowchart of a device management method in the Internet of Things provided by another embodiment of the present application. As shown in ±3, on the basis of FIG. 2, the method of the embodiment of the present application includes:

S301. The first device sends clock synchronization information to a second device connected to the first network, so that the second device is synchronized with the running clock of the first device according to the clock synchronization information.

In this embodiment, for the implementation of S301, reference may be made to S201, which will not be repeated here.

S302. The first device divides the second device into a target device group according to the self-awakening time period of the second device.

In this embodiment, each wake-up device has its own wake-up time period, wherein, for example, the wake-up time period of the wake-up device itself may be set by the wake-up device during production, or the wake-up device may be set by the wake-up device before accessing the network of the master clock device. It is configured by the master clock device in other local area networks. When the wake-up device is connected to the network of the master clock device, the wake-up device will be divided into device groups according to the wake-up time period of the wake-up device itself. Among them, if the wake-up time period of the existing wake-up device in the device group is consistent with the wake-up time period of the wake-up device itself, the wake-up device will be divided into the device group; if there is no wake-up time of the existing wake-up device in the device group For a device group whose period is consistent with the wake-up time period of the wake-up device, a new device group is created, and the wake-up device is divided into the newly created device group.

Or, when the number of wake-up devices connected to the master clock device exceeds the preset number, the master clock device divides the wake-up devices with the same wake-up time period into a group according to the wake-up time period of each wake-up device.

Or, when the number of wake-up devices connected to the master clock device network is large, or when most of the wake-up devices in the LAN have different wake-up time periods, if the wake-up devices with the same wake-up time period are divided into a group , there are many device groups divided, and each device group has fewer wake-up devices, which is less effective for solving the problems existing in the related art. Therefore, the wake-up devices can be divided into device groups whose wake-up time period corresponding to the device group is closest to the wake-up time period of the wake-up device itself. For example, the wake-up time period for the wake-up device itself is 10.3s. If there is a device group with wake-up time periods of 10s and 20s, the wake-up device is divided into a device group with a wake-up time period of 10s, and the wake-up device wakes up The time period is adjusted to 10s.

S303. The first device determines a wake-up time period corresponding to the target device group according to the wake-up time period of each device in the target device group.

In this embodiment, if the wake-up devices with the same wake-up time period are divided into a device group, the wake-up time period corresponding to the device group can be, for example, the wake-up time period of the wake-up device itself in the group, or the user can set the wake-up time period through the master clock device. The wake-up time period corresponding to each device group.

If the wake-up devices are divided into a device group whose wake-up time period is closest to the wake-up time period of the wake-up device itself, the wake-up time periods of the wake-up devices in the device group are close. At this time, the master clock device can select the wake-up time period of any wake-up device in the device group as the wake-up time period corresponding to the device group, or specify a wake-up time period for the device group, wherein the specified wake-up time period is the same as the wake-up time period. The variance between wake-up time periods within a device group that wakes up a device itself is minimal.

S304: The first device sends a wake-up time period to the target device group, so that each second device in the target device group uploads data through the first device when the wake-up time period arrives.

In this embodiment, for the implementation of S304, reference may be made to S203, which will not be repeated here.

In this embodiment, the first device sends clock synchronization information to the second device connected to the first device network, so that the running clock of the second device is synchronized with the running clock of the first device. Then, the first device divides the second device into the target device group according to the self-awakening time period of the second device, and determines the wake-up time period corresponding to the target device group according to the self-awakening time period of each device in the target device group , sending the wake-up time period corresponding to the target device group to the second device, so that each second device in the target device group uploads data through the first device when the same wake-up time period arrives. The number of wake-up times of the first device and the wake-up device is reduced, and the overall power consumption of the local area network is reduced. In addition, the wake-up devices are grouped, and the wake-up devices in the same device group upload work data in an orderly manner, which can also avoid the loss of work data and the untimely upload.

FIG. 4 is a flowchart of a device management method in the Internet of Things provided by another embodiment of the present application. As shown in ±4, on the basis of FIG. 2, the method of the embodiment of the present application includes:

S401. The first device sends clock synchronization information to a second device connected to the first network, so that the second device is synchronized with the running clock of the first device according to the clock synchronization information.

In this embodiment, for the implementation of S401, reference may be made to S201, which will not be repeated here.

S402. Obtain a classification instruction input by the user, where the classification instruction is used to indicate a functional category to which the second device belongs.

In this embodiment, when the wake-up device successfully connects to the network of the master clock device, if the master clock device is a device with a screen, the connected wake-up device, function options and input boxes are displayed on the screen of the master clock device. The input box is used for the user to input the function options corresponding to the wake-up device when the function categories corresponding to the function options displayed on the screen do not match the function of the wake-up device.

The user selects the corresponding function option according to the function of the wake-up device or inputs the function option corresponding to the wake-up device in the input box, and inputs the classification instruction to the master clock device.

It should be noted that the user can also input the classification instruction through other devices with a screen. Among them, the other device may be, for example, any wake-up device with a screen connected to the master clock device network, or a device with a screen connected to the master clock device through the interface entry address preset by the master clock device. Not limited.

S403. Divide the second device into a target device group according to the function category to which the second device belongs.

In this embodiment, after receiving the classification instruction input by the user, the master clock device obtains the function category of the wake-up device, and divides the wake-up device into corresponding device groups according to the function category of the wake-up device. In one embodiment, the function class to which the wake-up device belongs is the same as the function class to which each wake-up device in the corresponding device group belongs. For example, group audio devices into the same device group and smart toys into the same device group.

S404. The first device acquires the wake-up time period corresponding to the target device group set by the user.

The wake-up time period is generated by the first device according to the user's wake-up time period operation, or the first device receives and sends the wake-up time period operation from other devices according to the user's wake-up time period.

In this embodiment, the user sets the wake-up time period corresponding to each device group through the master clock device or other devices connected to the master clock device, so that the wake-up time periods of the wake-up devices in the device group are consistent.

S405: The first device sends a wake-up time period to the target device group, so that each second device in the target device group uploads data through the first device when the same wake-up time period arrives.

In this embodiment, for the implementation manner of S405, reference may be made to S203, which will not be repeated here.

It should be noted that, after the user equipment completes the wake-up time period of the device group, for the wake-up device newly assigned to the device group, the wake-up time period defaults to the wake-up time period corresponding to the device group.

In this embodiment, the first device sends clock synchronization information to the second device connected to the first device network, so that the running clock of the second device is synchronized with the running clock of the first device. Then, the first device obtains the classification instruction input by the user, and classifies the second device into the target device group according to the function category to which the second device belongs. Next, the first device obtains the wake-up time period corresponding to the target device group set by the user, and sends the wake-up time period corresponding to the target device group to the second device, so that each second device in the target device group arrives at the same wake-up time period Upload data through the first device. The number of wake-up times of the first device and the wake-up device is reduced, and the overall power consumption of the local area network is reduced. In addition, the wake-up devices are grouped, and the wake-up devices in the same device group upload work data in an orderly manner, which can also avoid the loss of work data and the untimely upload.

On the basis of any of the above embodiments, the method of the present application further includes: the first device sends clock synchronization information to the second device according to the synchronization time period, so that the second device and the running clock of the first device according to the clock synchronization information keep in sync.

In this embodiment, although the wake-up device connected to its network by the master clock device sends clock synchronization information, the running clock of the wake-up device is consistent with the master clock device. However, due to the different clock precisions between the wake-up devices and before the wake-up device and the master clock device, the running clocks between the wake-up devices and before the wake-up device and the master clock device are not synchronized after a period of time. Therefore, the user can preset the synchronization time period of the master clock device. When the synchronization time period arrives, the master clock device sends clock synchronization information to the wake-up device, so that the second device can maintain synchronization with the operating clock of the first device according to the clock synchronization information. .

On the basis of any of the above embodiments, the method of the present application further includes: when the wake-up time period corresponding to the target device group arrives, the first device sends a wake-up instruction to each device in the target device group to wake up the target device group. of each device.

In this embodiment, when the wake-up device wakes up and uploads data according to the wake-up time period, when the wake-up time arrives, the wake-up device can wake up autonomously, and enter the sleep state autonomously after the data upload is completed. However, when the autonomous wake-up function of the wake-up device is abnormal, or the wake-up device does not have the autonomous wake-up function, the master clock device sends a wake-up command to each device in the target device group when the wake-up time period corresponding to the target device group arrives to Wake up each device in the target device group.

The implementation method is as follows: the master clock device saves the wake-up time period corresponding to each device group. When the wake-up time period of each device group arrives, it starts to traverse the wake-up device. The device sends a wake-up command to wake up each device in the target device group. Or, when the master clock device finds that the wake-up device that should upload data has not uploaded data within the preset time, it sends a wake-up instruction to the corresponding wake-up device to wake up the wake-up device. In this way, it is possible to avoid untimely uploading of working data of the wake-up device, and to improve the intelligence of the local area network.
