Background

The intelligent home is embodied in an internet of things mode under the influence of the internet of things, various devices in the home are connected together through the internet of things, and multiple functions and means such as household appliance control, lighting control, curtain control and telephone remote control are provided. After various devices in the home are accessed to the network, the user can combine and classify the devices accessed to the network, that is, the devices of the same type can be used as a device group, and the user can uniformly control the devices in the combination in a broadcasting mode through the terminal device. The physical connection protocol between various devices of the smart home mainly includes a Wireless Fidelity (WIFI), a Bluetooth protocol (BLE), a ZigBee protocol, and the like.

When a user controls the equipment group through the terminal equipment, each control instruction sent by the terminal equipment and used for controlling each equipment in the equipment group is sent to each equipment in the equipment group through a remote network, such as an intelligent home cloud. Because the physical positions of the devices in the device group in the remote network are different from each other, and the network quality of the access to the remote network is different from each other, the time delay of each control instruction sent by the terminal device reaching each device cannot be consistent, so that each device in the device group cannot synchronously act.

The central control node may be a control device that may be connected to the network device group via a remote network, for example, the central control node may be a remote server, such as an intelligent home cloud platform. The intelligent home cloud platform can take the combination of cloud storage, cloud control and remote routing equipment as a central control node. Or the routing device may be a router or other electronic device with routing functionality. The control terminal and the central control node and the device group can communicate through a HyperText Transfer Protocol (HTTP), a restricted Application Protocol (CoAP) or other Application layer protocols, for the device group, the device group is located in a local network formed by a local router, the local router serves as an access point of a control instruction forwarded by the central control node, according to some embodiments of the present Application, the local network can be a WIFI network, the network where the control terminal is located can be a mobile network such as 3G/4G/5G or a wireless WIFI network, the remote network where the central control node is located can be a mobile network such as 3G/4G/5G or a wireless network, and the wireless network can be a WIFI network, a Zigbee wireless network, and the like.

According to the application scenario shown in fig. 1, the control of each device in the device group can be divided into three parts, namely, an execution instruction transmitting end, which corresponds to a control terminal and can be operated by a user; the execution instruction processing end corresponds to a central control node (an intelligent home cloud platform); and the controlled end corresponds to the device group, and for the controlled end, the controlled end is in a local network formed by the local router, and for the local network formed by the local router, the controlled end can be a Wireless-Fidelity (WIFI) network.

Based on the above description, the main workflow of the instruction processing side and the controlled side is described below.

The following describes a workflow of an instruction processing end in an embodiment of the present application with reference to fig. 2(a) and fig. 2(b), where fig. 2(a) is a schematic flowchart of a device control method provided in the embodiment of the present application, and fig. 2(b) is a schematic flowchart of authentication and authorization performed by a device in a device group provided in the embodiment of the present application. Fig. 2(a) illustrates a device control method for controlling a device group (designated device group) in an application scenario as in fig. 1, the device group including one or more devices under a local network, the designated device group referring to a device group to be controlled selected by a user through a control terminal.

It is necessary for the device group and each device in the device group to authenticate and authenticate each device when the device joins the device group and other devices are controlled by the target device in the device group. As shown in fig. 2(b), the process of authenticating and authenticating each device is specifically as follows:

s200: the user creates a device group through the control terminal.

Specifically, in some embodiments of the present application, a user may create a device group through a control terminal, where the user selects the device 1, the device 2, and the device 3 on a display panel of the control terminal, and adds the device 1, the device 2, and the device 3 to the same device group, thereby completing creation of the device group.

S201: after the user creates the device group through the control terminal, the control terminal may preset a key authcode of the device group and inform the key authcode to the central control node. A join device group instruction carrying the key authcode is sent by the central control node (which may be a control device, such as a routing device) to the respective devices (device 1, device 2, and device 3).

S202: and each device in the device group encrypts and stores the cipher key authcode sent by the central control node. For the key authcode, the key authcode may be refreshed at a predefined time interval by a user at the control terminal, or refreshed at the time of reassembling the device group, where the reassembling the device group refers to adding a new device to the device group or exiting a device in the device group, and the encryption mode for the key may be a symmetric encryption mode or an asymmetric encryption mode, and the like.

S203: the central control node selects device 1 as a target device from devices 1, 2, and 3, and sends a control message to device 1 in a unicast manner, and after receiving the control message, device 1 executes S204.

After the device 1, the device 2, and the device 3 store the key authcode, the central control node selects a target device from the device group and controls the target device in the device group, and authentication and authorization are required when the central control node sends a control message to control the target device and the target device broadcasts the control message to other devices in the control device group.

S204: the device 1 broadcasts the control message to the device 2 and the device 3, randomly generates a sn1 random number, and calculates two TK keys and AK keys according to an encryption algorithm configured in advance by the device 1 to encrypt the control message and then broadcast the encrypted control message.

In some embodiments of the present application, an Advanced Encryption Standard (AES) is taken as an example of the Encryption algorithm, and of course, the Encryption algorithm may also be another Encryption algorithm, and the embodiments of the present application are not limited herein. The TK key and the AK key can be AES-128 encryption keys. The TK key is used to encrypt the control message data part of the broadcast of the network device 1. The AK key is used to sign and verify integrity of a control message sent by the network device 1.

For TK keys, the calculation formula may be PBKDF2(authcode, sn1, 1); the formula for AK key may be PBKDF2(TK,0,1), Salt ═ 0.

S205: after receiving the encrypted control message sent by the device 1, the devices 2 and 3 decrypt the encrypted control message by using the stored key authcode received by the step SS 202.

In some embodiments of the present application, as shown in fig. 2(a), an apparatus control method provided in an embodiment of the present application includes:

s20: the central control node receives an execution instruction for instructing the group of devices to perform a predetermined action.

The predetermined action refers to an execution action corresponding to the execution instruction, which is sent by the user through the control terminal and received by the central control node. Taking the device as an intelligent switch as an example, the execution instruction may be an instruction sent by the user through the control terminal to instruct the intelligent switch to be turned off. S21: and the central control node selects one device from the device group as a target device.

According to some embodiments of the present application, there may be many implementations for S21, and in some embodiments of the present application, the implementation for S21 may be as shown in fig. 3(a) and 3(b), and the implementation flow for S21 in fig. 2(a) in this embodiment of the present application is described below with reference to fig. 3(a) and 3 (b). Fig. 3(a) is a schematic flowchart of a method of S21. Fig. 3(b) is a flow for forming an association data table for each device in the same device group according to the embodiment of the present application.

According to some embodiments of the present application, as shown in fig. 3(a), S21 includes:

s210: the central control node receives respective associated data tables reported by the devices in the slave device group, and the associated data tables describe the states of the devices and the association between the devices.

In some embodiments of the present application, the state of the device itself refers to the device identification of the device, the signal strength of the device in the local network, the device group identification of the device group in which the device is located, and the like. The association between the devices refers to an association relationship between the devices that are mutually influenced or controlled, that is, the devices in the same device group are associated, and a target device in the same device group can control other devices in the device group to be mutually controlled.

S211: and the central control node selects one device from the device group as a target device based on each associated data table.

According to some embodiments of the application, the association data table may include: the device identification of the device, the signal strength of the device in the local network, the device group identification of the device group in which the device is located.

According to some embodiments of the present application, taking an association data table uploaded by a target device as an example, the form of the association data table may be:

[ { target device, device group ID },

{ device 1, device group ID, signal strength 1},

{ device 2, device group ID, signal strength 2},

{ Equipment 3, Equipment group ID, Signal Strength 3} ]

Further, in some embodiments of the present application, as shown in fig. 3(c), assuming that five devices a, b, c, d, and e are accessed into the local network, for a network formed by these 5 devices, the device group IDs of the devices a, b, and c are the same and are all 0x1001, and the device d is a device newly added to the device group with the device group ID of 0x1001 and is associated with the signal strength of the device a, and may be controlled by a, and the device e is an independent device. For example, if the target device is a, and the slave devices are b, c, d, and e, the form of the association data table formed by a may be:

[{a,0x1001}{b,0x1001,-55},{c,0x1001,-76},{d,0x1002,-63}]

here, the device a is the target device, and the device a and the device b and the device c are both in the device group whose ID is 0x 1001. And after the target equipment a receives the control message sent by the central control node, the control message is respectively sent to the equipment b and the equipment c. Here, the number of times of transmission of the control command in the device group 0x1001 may be expressed in terms of the number of hops. For example, device a sends control messages to device b and device c; after the devices b and c receive the control message, the execution action indicated by the control message is executed, and then the transmission of the whole control message is completed. Therefore, in the device group, the control message is transmitted from the device a to the devices b and c, respectively, and the transmission path of the control message is transmitted only once, and the hop count is 1. If another device f exists in the device group and the device c controls the device f, and the device c sends the control message to the device f again, the sending path of the control message is as follows: the control message is sent to the device c by the device a, and then sent to the device f by the device c, the hop count is 2 when the control message is sent for 2 times, the value of the hop count can reflect the sending path of the control message, and the sending path with the smaller hop count value is selected as the optimal sending path to send the control message, so that the forwarding times of the control message are reduced, and the control efficiency is improved.

Similarly, taking the target device as b and the slave device having a relationship with b as a, c, the formed association data table is:

[{b,0x1001},

{a,0x1001,-54},

{c,0x1001,-63}]

taking target equipment as c and slave equipment with the association relation with the c as a and b, and forming an association data table as follows:

[{c,0x1001},

{a,0x1001,-77},

{b,0x1001,-82}]

taking the target device as d and the slave device having the association relation with d as a, the formed association data table is as follows:

[{d,0x1002},

{a,0x1001,-64}]

for an isolated device e, the associated data table is formed as follows:

[{e,0x1001}]

after the devices a, b, c, d, and e respectively report their association tables to the central control node, the central node forms a forwarding path of the control message of each network device group, that is, a forwarding path of the control message whose device group ID is 0x1001 (an independent device e, and a forwarding path of the control message whose device group ID is 0x 1002), and each forwarding path forms a broadcast policy table, where the broadcast policy table specifically includes:

[ { path 1 set 0x1001, [ { a, b, c },1] },

{ path 2 set 0x1002, [ { d },0] },

{ Path 3 set 0x1001, [ { e },0] }, ]

For the devices a, b, and c, which are located in the device group with the device group ID of 0x1001, the central control node unicast-transmits the control message to the device a, and then the device a transmits the control message to the device b in a broadcast manner, respectively, and the device c completes the control of the devices b and c, and the control message is forwarded once in the device group, that is, the hop count of the path 1 group is 1. For device d, although it may be controlled by device a, it belongs to the device group with device group ID 0x1002, and therefore, device d may be used as a single device to which a control message is sent by the central control node, that is, the hop count of the path 2 group is 0; for an isolated device e, which is used as a single device, the central control node directly sends a control message to the device e, and the hop count of the path 3 group is 0.

It is to be understood that, for the group broadcast policy table, which is a representation of a transmission path of the control message for each device group, if there are i device groups in common, the group broadcast policy table formed by the i device groups may adopt t (p) ═ F(s)₁,s₂,...,s_i) The method includes that a central control node selects a target device in each device group, the target device sends a control message to the rest slave devices in the device group, and a sending path of the control message of each device group can be specifically represented in the following form:

{ path 1 group ID, [ { target device, device 1, device 2 … } ], hop count },

{ path 2 group ID, [ { target device, device 3, device 4 … } ], hop count },

{ path 3 group ID, [ { target device, device 5, device 6 … } ], hop count },

…]

it should be noted that, for 1 or more devices in the device group, when one device is included in the device group, the central control node may send an instruction to the individual device to complete the control of the device, and when multiple devices are included in the device group, the central control node may unicast a control message to a target device in the device group, and then the target device may rebroadcast the control message to the remaining slave devices in the device group.

In the embodiment of the present application, the local network may be a WIFI network, the network where the mobile phone is located may be a mobile network or a wireless network such as 3G/4G/5G, and the remote network where the central control node is located may be a mobile network or a wireless network such as a WIFI network or a Zigbee wireless network. The interaction method shown in fig. 10 includes:

S100: the user creates the device group through the mobile phone. The user may set the lamp 1, the lamp 2, and the lamp 3 to be in the same device group through a mobile phone by using the mobile phone to create the device group, and after the user selects the lamp 1, the lamp 2, and the lamp 3 to be in the same device group through the mobile phone, the mobile phone assigns an ID, such as 0x1001, to the device group, adds the device IDs of the lamp 1, the lamp 2, and the lamp 3, respectively, and binds the device IDs of the lamp 1, the lamp 2, and the lamp 3 to the ID0x1001 of the device group in which the device group is located.

S101: the mobile phone presets a secret key authcode of the equipment group.

S102: the mobile phone creates an equipment group and a key authcode of a preset equipment group, and sends an execution command and the key authcode to the central control node. In some embodiments of the present application, the execution command includes information such as a device group ID specified by the user to be controlled in the mobile phone, and device IDs of the light fixture 1, the light fixture 2, and the light fixture 3 in the device group. After receiving the execution command and the key authcode, the central control node sends an equipment group joining instruction carrying the key authcode to the lamps 1, 2 and 3 in the remote network accessing the central control node through the local routing equipment. The join device group command carries information of ID0x1001 of the device group, and device IDs of the luminaire 1, the luminaire 2, and the luminaire 3 included in the device group. After the lamps 1, 2 and 3 in the remote network where the central control node is located are connected to receive the command sent by the central control node, the lamps 1, 2 and 3 whose device IDs are bound to the device group whose device group ID is 0x1001 join the device group whose device group ID is 0x 1001.

S103: the lamps 1, 2 and 3 receive an equipment group adding instruction carrying a secret key authcode; the lamps 1, 2, and 3 store the authcode in an encrypted manner, and add the encrypted key to the device group having the device group ID of 0x 1001. Then, the luminaire 1, the luminaire 2, and the luminaire 3 actively broadcast the ID of the device group in which the luminaire itself is located, and the signal strength in the local network in which the luminaire itself is located, respectively. Alternatively, after receiving the device request, the luminaires 1, 2, and 3 may broadcast the ID of the device group in which they are located in response to the request, thereby forming the association data table.

The process of forming the association data table by the device luminaire 1 will be described by taking the example that the luminaires 2 and 3 actively broadcast the device group ID where they are located. The lamp 1 monitors the ID of the equipment group where the lamp 2 is located and the ID of the equipment group where the lamp 3 is located, which are broadcasted by the lamp 2, and distinguishes that the lamp 2, the lamp 3 and the lamp 1 are in the same equipment group; then, the luminaire 1 constructs the IDs of the device groups of the sensed luminaires 2 and 3, the device IDs of the luminaires 2 and 3, and the signal strengths of the local networks in which the luminaires 2 and 3 are located, together with the device IDs and the device group IDs of the luminaires 1, into an association data table of the luminaire 1. In addition, for the process of forming the association data table for the lamp 2 and the lamp 3, reference may be made to the process of forming the association data table for the lamp 1, and details of the embodiment of the present application are not repeated herein.

Further, in some embodiments of the present application, the encryption algorithm may be a symmetric encryption algorithm, a digital signature encryption algorithm, a public key encryption algorithm, and the like.

S104: luminaire 1, luminaire 2 and luminaire 3 form an association data table.

S105: and reporting the associated data table to the central control node. Thus, the lamps 1, 2 and 3 complete the report of the associated data table. And the central control node selects the target equipment according to the associated data table reported by each equipment. For example: and if the signal intensity of the lamp 1 in the local network is the strongest, selecting the lamp 1 as the target equipment in the equipment group, and executing the following steps.

S106: the central control node sends the group control commands to the luminaires 1 in a unicast manner.

S107: luminaire 1 broadcasts the set of control commands to luminaires 2 and 3. When the group of control commands is broadcast, the lamp 1 randomly generates a sn1 random number, and calculates two TK keys and AK keys according to a pre-configured encryption algorithm to encrypt and sign the group of control commands.

S108: after the lamps 2 and 3 receive the encrypted group control command sent by the lamp 1, the encrypted group control command is decrypted by using the key authcode received and stored in S103, and an execution action indicated by the execution instruction in the group control command is executed, such as turning off the lamps.

According to a common mode, the central control node sends a control instruction to each device in the device group, and because the position of each device in the device group on a network physical layer and the network quality of each device accessing the central control node network are different, the time for the control instruction to reach each device in the device group is different. The purpose of simultaneous action of all the devices in the device group cannot be achieved. According to the device control method for the network routing device provided by the embodiment of the application, after the network routing device receives the execution instruction, one device is selected from the device group as the target device. The target device is a device belonging to the device group and used for controlling other devices in a designated device group in the local network, and when the local network controls other devices in the same device group, the target device and other devices are both in the local network, so that the target device can realize the purpose of locally controlling other devices, and can realize the function of simultaneously controlling the devices in the device group, so that the devices in the device group synchronously execute the predetermined action indicated by the control instruction.

In another embodiment of the present application, in the embodiment shown in fig. 10, the device group may include a luminaire 1, a luminaire 2, a luminaire 3, and a target device. The target device may be a routing device providing a local WIFI network, or may be other devices located in the local WIFI network, such as a smart television, a smart refrigerator, and the like. The central control node sends the group control command to the target device, and then the target device broadcasts the group control command to the other devices (the lamp 1, the lamp 2 and the lamp 3) in the device group, so that the other devices (the three lamps) in the device group simultaneously execute the action corresponding to the control command, such as simultaneously turning on or off or changing colors. That is to say, in this embodiment, a certain device in the local WIFI network may be selected as a target device in the device group, and then other devices in the device group may be controlled to operate simultaneously by the target device, and the target device may not need to operate simultaneously with other devices in the device group. Optionally, there may be multiple device groups in the local WIFI network, and the target device may be a target device in the multiple device groups. For example, the aforementioned target device may also be a target device in another device group (including the target device, enclosure 1, enclosure 2, and enclosure 3); when the user wants to control the three speakers to operate simultaneously, the central control node may send the group control command to the target device, and then the target device broadcasts the control command to the three speakers, so that the three speakers operate simultaneously.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the invention has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and these modifications or substitutions do not depart from the spirit of the corresponding technical solutions of the embodiments of the present invention.
