Fig. 4 illustrates a software configuration diagram in the intelligent control device 200 according to some embodiments. Referring to fig. 4, in some embodiments, the system is divided into four layers, which are an Application (Applications) layer (abbreviated as "Application layer"), an Application Framework (Application Framework) layer (abbreviated as "Framework layer"), an Android runtime (Android runtime) and system library layer (abbreviated as "system runtime library layer"), and a kernel layer from top to bottom.

In some embodiments, the smart control device comprises a smart television, a television remote controller, a mobile phone, a refrigerator, a sound box, and other smart devices. The intelligent control devices are typically available in a networked manner to provide the user with richer content. The intelligent control devices can be connected with different networks according to different positions. For example, in the same community, the same residential building or the same household, since the distance between the intelligent control devices satisfies a certain network coverage, the intelligent control devices in the area can be connected to the same network, and the network to which the intelligent control devices are connected together is a local area network. And for the intelligent control equipment at other positions, the intelligent control equipment needs to be connected to another network to form another local area network.

In the same local area network, one intelligent control device can control the other intelligent control device to execute corresponding actions, and user experience is improved.

Fig. 6 illustrates an existing local area network undirected communication topology in accordance with some embodiments. Referring to fig. 6, a plurality of intelligent control devices are connected to the same lan through the same router. In this scenario, when a user needs to use one intelligent control device to implement control of another intelligent control device, because the intelligent control devices are not aware of each other, a command sent by one intelligent control device (master intelligent control device) cannot be directed to a target intelligent control device (controlled intelligent control device), for example, a broadcast command sent by device 1 may be received by devices 2, 3, 4, 5, etc. in the same lan.

There are several disadvantages in this process: firstly, one intelligent control device sends a control instruction, and a plurality of intelligent control devices monitor, which causes other non-target intelligent control devices to be frequently interfered, so that resources of other non-target intelligent control devices are wasted. Secondly, the security problem is that only the private information received by the target intelligent control device is expected to be received by other intelligent control devices and cause leakage, and especially when an external device (such as a mobile phone in a non-community accesses the current local area network through a router), the security risk is more serious. Third, inefficiency may exist in which there is a device that responds to the control instruction of the master intelligent control device that is not the target intelligent control device, resulting in a failure of communication between the master intelligent control device and the target intelligent control device.

Therefore, when communication is carried out among a plurality of intelligent control devices in the same local area network, directional communication cannot be realized due to mutual no perception among the intelligent control devices, and the efficiency is low.

Therefore, in order to implement directional communication of each intelligent control device in the same local area network, an embodiment of the present invention provides a multi-device communication method, where any device in the local area network is used as a master control device, when the master control intelligent control device needs to control another intelligent control device, a generated device control instruction is first sent to the master control device, and then the master control device returns device information of the controlled intelligent control device to the master control intelligent control device, and the master control intelligent control device implements directional communication with the controlled intelligent control device based on the device information. The master control equipment stores equipment information of all intelligent control equipment in a local area network where the master control equipment is located.

Fig. 7 illustrates a topology diagram of a local area network directed communication approach in accordance with some embodiments. Referring to fig. 7, in the same local area network, to implement directional communication among multiple devices, one of the intelligent control devices in the local area network needs to be selected as a master control device. The master control device can select an intelligent control device in a long-term working or standby state, for example, an intelligent sound box in a local area network which works or is in a standby state for a long term can be set as the master control device. Device 3 is selected as the overall control device in fig. 7.

In some embodiments, the master control device needs to monitor whether there is a master control intelligent control device sending a device control instruction to another controlled intelligent control device in the local area network in real time, and therefore, the master control device needs to be always in a state capable of monitoring the instruction, for example, the master control device needs to be in a non-power-off state.

In the same local area network, because the communication information (such as IP address) of each other is not known among the intelligent control devices, directional communication among the multiple devices cannot be realized. Therefore, in order to realize the directional communication among the multiple devices in the local area network through the master control device, the device information of each intelligent control device in the local area network can be stored in the master control device in advance.

The master control device stores device information of all intelligent control devices in the current local area network, all the intelligent control devices in the current local area network refer to all devices which are accessed to the current local area network and normally operate, and devices which are not accessed to the local area network due to power failure, faults, autonomous non-access and the like are not all the intelligent control devices in the current local area network required by the application. The device information is used for realizing the unique identification of the corresponding device, and the device information comprises characteristic information, communication information and function information. The characteristic information refers to a value for characterizing a unique characteristic of the smart control device, such as a device name, a nickname, a physical location of the device (e.g., a location of a room where the device is located), a MAC address (device ID), and the like. The communication information is used to implement information transfer between devices, such as IP addresses of the devices. The function information is used for representing the external functions of the intelligent control equipment, for example, the external functions of the air conditioning equipment are the functions of startup and shutdown, temperature, wind direction, mode and the like.

The equipment information of the master control equipment can be synchronously sent to each intelligent control equipment in the local area network, so that any intelligent control equipment in the local area network can communicate with the master control equipment. And because the equipment information of the master control equipment is stored in each intelligent control equipment in the same local area network, the equipment control instruction sent by any intelligent control equipment in the same local area network can be preferentially received by the master control equipment and cannot be received by other intelligent control equipment.

In some embodiments, the device information of each intelligent control device in the local area network stored in the master control device may be manually input by a user, and each device information is stored in the form of a controlled device list.

If the master control device stores the information of each device in an automatic mode, the device information of any device connected to the local area network can be stored. If the device is not located in the location for a long time, if the device is only a visitor device and does not stay in the coverage of the lan all the time, if the device of the device is also automatically stored, it may happen that the device is not in the coverage of the lan when the master control intelligent control device needs to control the device, and the sending of the control request cannot be realized, that is, effective device control cannot be performed. In addition, there may be a case where a device in the same lan does not have a function of receiving a control command from another device, which may result in failure of device control.

It can be seen that if the master control device adopts an automatic storage mode when storing information of each device in the local area network, the device information which does not support the controlled function or is not in the coverage range of the local area network for a long time can be stored, so that invalid data in the controlled device list is more, the situation that effective control cannot be performed can be generated, and the storage space can be wasted.

Therefore, the master control device in the present application adopts a mode of manually inputting device information, a user manually inputs device information which supports each controlled function, needs to be controlled, and is located in the same local area network into the master control device, and each manually input device information is stored in a local cache of the master control device. The stability of the controlled equipment list can be ensured by manually inputting the information of each piece of equipment, the equipment in the controlled equipment list can be ensured to be controlled to act, the safety is high, and the control process from the master control intelligent control equipment to the controlled intelligent control equipment is ensured to be effectively carried out; and the user can add new equipment information or delete the equipment information which does not need to execute the controlled action in real time, so that the maintainability of the controlled equipment list is improved, and the user experience is good.

The method comprises the steps that a main control intelligent control device is a device for initiating a request, when an action instruction is initiated, device information of a target intelligent control device (controlled intelligent control device) is inquired in a master control device, and an IP address and the like of the device are obtained; and then, directional instruction sending is carried out through the unique device information such as the IP address or the device ID and the like, so that the action instruction is ensured to be successfully received only by the target intelligent control device. As shown in fig. 7, the device 1 is a master intelligent control device, the device 5 is a controlled intelligent control device, the device 1 first sends a device control instruction to the device 3, and then queries the device information of the device 5, and then the device 1 and the device 5 realize directional communication.

By the scheme, communication and control among multiple devices of the local area network are carried out, directional information transmission among the devices can be realized, and interference to other non-relevant devices in the communication process is avoided; meanwhile, information leakage is avoided, and safety is improved; the direct form of the information is more beneficial to ensuring the high efficiency of the communication process.

FIG. 8 illustrates a flow diagram of a multi-device communication method according to some embodiments; fig. 9 illustrates a data flow diagram of a multi-device communication method according to some embodiments. The embodiment of the invention provides an intelligent control device, which is applied to a main control intelligent control device end for sending a device control instruction, and comprises: a controller configured to perform the following steps when performing the multi-device communication method shown in fig. 8 and 9:

and S11, receiving a device control instruction which is triggered by a user and used for controlling the controlled intelligent control device, wherein the device control instruction carries target characteristic information and target control action of the controlled intelligent control device, and the controlled intelligent control device, the master intelligent control device and the master control device are in the same local area network.

In the same local area network, there are main control equipment, main control intelligent control equipment and multiple controlled intelligent control equipment. The master control device, the master control intelligent control device and the controlled intelligent control device can be any device in the same local area network.

In order to facilitate the user to trigger the device control instruction, the main control intelligent control device may be a device closer to the user, and the controlled intelligent control device may be a device farther from the user, so that the user can control the device farther from the user to execute a corresponding action by using the device closer to the user. In a feasible embodiment, the main control intelligent control device is a refrigerator in a kitchen, the controlled intelligent control device is an air conditioner of a main bedroom and a bedroom, and the main control device is an intelligent sound box.

When a user needs to utilize the master control intelligent control device to control the controlled intelligent control device to execute corresponding actions, the mode of the device control instruction triggered by the user can be a voice mode or a mode of manually triggering the corresponding APP.

In some embodiments, when the device is controlled in a voice mode, the main control intelligent control device may be configured with a voice module for recognizing a voice instruction of a user in real time. For example, when the user is located near the master control intelligent control device and speaks a voice "turn on the air conditioner in the master bedroom", the voice module recognizes the voice and then obtains a voice text.

And analyzing the voice text to divide characteristic information and control action. For example, the characteristic information may be the name of the controlled object, such as "air conditioner in master bedroom" and the control action is "open".

The main control intelligent control device generates a device control instruction based on the voice of the user, and the device control instruction carries the target characteristic information and the target control action of the controlled intelligent control device so as to control the controlled intelligent control device to execute the corresponding action.

In some embodiments, when the control of the device is executed in a manner of manually triggering the corresponding APP, the user operates the master control intelligent control device, a controlled device list is presented in the APP configured by the master control intelligent control device, and the controlled device list is generated by the master control device based on the input device information and is respectively sent to the intelligent control devices of the same local area network.

And presenting the characteristic information and the function information of each device in the controlled device list. And the user selects one device from the controlled device list as the controlled intelligent control device based on the characteristic information, and determines the control action required to be executed by the controlled intelligent control device based on the corresponding function information.

And generating a device control instruction for controlling the controlled intelligent control device based on the target characteristic information and the target control action manually selected by the user so as to control the controlled intelligent control device to execute the corresponding action.

S12, sending a device control instruction to a master control device, wherein the master control device stores characteristic information and communication information of all intelligent control devices accessed to the same local area network, and the device control instruction is used for instructing the master control device to inquire target communication information of the controlled intelligent control device based on the target characteristic information;

because the device control instruction triggered by the user does not include the communication information of the controlled intelligent control device, namely, after the user generates the device control instruction, the main control intelligent control device cannot directly communicate with the controlled intelligent control device. The communication information of the controlled intelligent control device is stored in the master control device, so that the master control intelligent control device needs to acquire the communication information of the controlled intelligent control device from the master control device first, and then the directional communication between the master control intelligent control device and the controlled intelligent control device is realized.

After the main control intelligent control equipment generates an equipment control instruction, the equipment control instruction is sent to the master control equipment. The master control equipment stores equipment information of all normally running intelligent control equipment accessed into the local area network, and the equipment information comprises characteristic information, communication information and function information.

After receiving the device control instruction, the master control device queries the target communication information of the corresponding controlled intelligent control device in the local cache based on the target characteristic information of the controlled intelligent control device carried in the device control instruction.

For example, a refrigerator (master intelligent control device) in a kitchen carries an "air conditioner of a master bedroom" (target characteristic information) to a controlled device list stored in an intelligent sound box (master control device) for inquiry, and if device information corresponding to the target characteristic information can be inquired, the fact that the controlled intelligent control device exists and is on the internet is indicated. If not, the query is failed, which indicates that the controlled intelligent control equipment to be controlled by the current user is offline and does not support communication temporarily or does not exist.

And after the master control equipment successfully queries the equipment information, the complete equipment information of the controlled intelligent control equipment can be obtained and sent to the master intelligent control equipment. The complete equipment information comprises characteristic information, communication information and function information of the controlled intelligent control equipment.

In some embodiments, the master control device may return all the complete device information of the controlled intelligent control device to the master intelligent control device, and the master control device may also return only the target communication information of the controlled intelligent control device to the master intelligent control device. Which strategy is specifically implemented may depend on the actual application.

It should be noted that, the process of the master control device executing the complete device information query of the controlled intelligent control device may refer to steps S21 to S23 and related contents provided in the subsequent embodiments, which are not described herein again.

And S13, receiving target communication information of the controlled intelligent control equipment returned by the master control equipment.

And S14, sending the device control command to the controlled intelligent control device based on the target communication information, and enabling the controlled intelligent control device to execute the target control action.

After inquiring the target device information of the controlled intelligent control device based on the device control instruction sent by the master control intelligent control device, the master control device can return the target device information of the controlled intelligent control device to the master control intelligent control device.

For example, the general control device smart speaker feeds back the queried information of the device name, nickname, device physical location (e.g., the room location), MAC address (device ID), IP address, external provision function, and the like of the "air conditioner in the master bedroom" to the refrigerator device in the kitchen.

After the master intelligent control device obtains the target communication information (such as an IP address) of the controlled intelligent control device, the master intelligent control device may establish a directional communication connection with the controlled intelligent control device based on the target communication information, and send a device control instruction carrying a target control action to the controlled intelligent control device. For example, a refrigerator in the kitchen controls an air conditioner of the master bedroom to be powered on and operated through a specific protocol based on the ID address.

And after the controlled intelligent control equipment receives the equipment control instruction, the target control action can be executed. For example, the air conditioner of the master bedroom performs an "on" action.

In some embodiments, after responding to the device control command of the master intelligent control device, the controlled intelligent control device may simultaneously obtain the device information of the master intelligent control device that sent the device control command, so as to facilitate feedback of the bidirectional communication.

The controlled intelligent control device can directionally communicate the instruction execution result of executing the set control instruction through the protocol based on the device information of the master control intelligent control device, and feed back the instruction execution result to the master control intelligent control device sending the device control instruction, so that the master control intelligent control device can timely acquire the state or the result of the controlled intelligent control device after executing the instruction.

For example, after the "air conditioner in the master bedroom" is successfully started, the "refrigerator in the kitchen" is notified that the "refrigerator in the kitchen" is successfully started, and other state information (such as temperature, mode, wind direction and the like) of the current air conditioner can be synchronously transmitted to the "refrigerator in the kitchen".

In some embodiments, in the device control instruction sent by the master intelligent control device, the carried target feature information of the controlled intelligent control device may be a device name, a nickname, or the like. Both device names and nicknames can be customized by the user, and the situation that the names of a plurality of devices are the same usually does not occur.

In some embodiments, the naming of each intelligent control device by a user may have a duplicate name, so that the master control device cannot accurately determine which controlled intelligent control device the user needs to control when inquiring; or when a user triggers a device control instruction in a voice mode, target characteristic information carried in the instruction is not standard, so that the master control device cannot inquire the target controlled intelligent control device during inquiry, but the controlled intelligent control device actually exists and is in a network state. All of the above conditions affect the normal communication between multiple devices.

Therefore, in order to facilitate normal communication among the multiple devices in the local area network, under the condition that duplicate names exist or the characteristic information required by query is not matched but similar, the master control device provides the associated characteristic information, so that the user can conveniently realize normal operation of the multiple device communication through interaction again.

Specifically, when the master control device does not inquire the target communication information, after sending the device control instruction to the master control device, the controller is further configured to execute the following steps:

and step 121, when the master control device does not inquire corresponding target communication information based on the target characteristic information, receiving a plurality of associated characteristic information generated based on the characteristic information and returned by the master control device.

And step 122, responding to an operation instruction generated by the user on any associated characteristic information, sending a query instruction carrying the specified associated characteristic information to the master control device, wherein the query instruction is used for instructing the master control device to query the target communication information of the controlled intelligent control device based on the specified associated characteristic information.

The situation that the master control equipment does not inquire corresponding target communication information based on the target characteristic information comprises two situations, wherein one situation is that the master control equipment does not inquire the unique characteristic information which is consistent in matching locally based on the target characteristic information, namely the target characteristic information generated by a user is not standard or standard and cannot be matched with the pre-stored equipment information; the other is that based on the target characteristic information, the master control device locally queries a plurality of matched and consistent characteristic information, namely the device condition with a duplicate name exists in the pre-stored device information.

Under the two conditions, the master control device can provide associated characteristic information for the master control intelligent control device, so that the user can conveniently perform secondary interaction, and normal communication of multiple devices in the local area network is facilitated.

The associated characteristic information may be characteristic information, which is locally stored in the master control device and has similarity with the target characteristic information exceeding a threshold, for example, the target characteristic information is a device name "master-sleeping air conditioner", and the locally stored characteristic information of the master control device is actually "master-sleeping air conditioner 1, master-sleeping air conditioner 2, master-sleeping air conditioner 3", and the like, so that the master-sleeping air conditioner 1, the master-sleeping air conditioner 2, and the master-sleeping air conditioner 3 are all associated characteristic information.

The associated feature information may also be a plurality of feature information consistent with the target feature information, for example, if the target feature information is a nickname "floret", the devices which are the nickname "floret" include an air conditioner, a television, a mobile phone, and the like, and the "floret air conditioner", "floret television", and "floret mobile phone" are all associated feature information.

The main control intelligent control equipment carries out information prompt on the associated characteristic information sent by the master control equipment so as to inquire a user to which equipment a control instruction of the equipment is specifically sent. The information prompting mode comprises interface display, voice broadcast and other modes.

In some embodiments, if the master intelligent control device is a device with a display, the associated feature information may be displayed in the display of the master intelligent control device in an interface display manner. The user can select one of the characteristic information as the designated associated characteristic information in the display of the main control intelligent control device, generate a query instruction and send the query instruction to the main control device again. And after receiving the query instruction, the master control equipment queries the target communication information of the controlled intelligent control equipment based on the specified associated characteristic information.

In some embodiments, if the master smart control device is a device that does not have a display but has a speaker, the associated feature information may be presented in a voice announcement. After hearing the associated characteristic information reported by the main control intelligent control equipment, the user can perform secondary voice interaction with the main control intelligent control equipment in a voice mode to determine the specified associated characteristic information, generate a query instruction and send the query instruction to the main control equipment again. And after receiving the query instruction, the master control equipment queries the target communication information of the controlled intelligent control equipment again based on the specified associated characteristic information.

Therefore, when the master control intelligent control device inquires the communication information of the controlled intelligent control device from the master control device, the master control device firstly matches the target characteristic information in the device control instruction with each locally stored characteristic information, and if the matching is consistent, the corresponding communication information can be directly returned to the master control intelligent control device so as to perform the subsequent process. If the consistent characteristic information is not matched or a plurality of identical characteristic information is matched, the associated characteristic information needs to be returned to the main control intelligent control device, so that the user can conveniently carry out secondary interaction to determine the target controlled intelligent control device to be controlled, and the normal communication among the multiple devices in the local area network is ensured.

In some embodiments, after receiving the device control instruction sent by the master intelligent control device, the controlled intelligent control device needs to return an instruction execution result and current state information. The master control intelligent control device can perform the next control process based on the current state after acquiring the current state of the controlled intelligent control device after executing the device control instruction once, and does not need to send the target communication information again after inquiring the target communication information through the master control device, so that the subsequent single-line contact can be realized, and the communication efficiency is improved.

Specifically, after completing the primary device control, the controller is further configured to perform the steps of:

and 151, after the master control intelligent control device and the controlled intelligent control device establish the directional communication connection based on the target communication information, receiving a next device control instruction triggered by the user and used for controlling the controlled intelligent control device.

And 152, sending the next device control instruction to the controlled intelligent control device based on the communication information, so that the controlled intelligent control device responds to the next device control instruction to execute the corresponding control action.

After the main control intelligent control device establishes directional communication connection with the controlled intelligent control device based on the communication information of the controlled intelligent control device inquired by the main control device, if a user still needs to utilize the main control intelligent control device to send a control instruction to the controlled intelligent control device, the main control device does not need to inquire the communication information and then realizes communication, but can directly carry out subsequent single-line contact, and the single-line contact has no timeliness. That is to say, after the communication is realized between the two devices in the local area network once, the subsequent communication does not need to request the master control device, but can be directly carried out, so as to improve the communication efficiency.

At this moment, if the user generates the next device control instruction again, the master control intelligent control device can directly send the next device control instruction to the controlled intelligent control device, so that the controlled intelligent control device can quickly execute the control action carried by the next device control instruction, and the communication efficiency is high.

For example, based on the foregoing embodiment, after the "air conditioner in the master bedroom" (controlled intelligent control device) is successfully turned on, the user may continue to send the device control instruction "reduce the temperature of the air conditioner in the master bedroom" by using the "refrigerator in the kitchen" (master intelligent control device), and at this time, the master intelligent control device may directly perform directional communication without inquiring the communication information of the "air conditioner in the master bedroom" from the master intelligent control device. The control instruction of the equipment carrying the temperature reduction is sent to the air conditioner of the master bedroom, the temperature of the air conditioner of the master bedroom can be reduced once based on the current temperature value, and the amplitude of each temperature reduction can be 1 degree.

In some embodiments, single-wire contact can be always performed because the function of maintaining continuous directional communication among multiple devices in the local area network which completes one effective communication is not time-efficient. However, if the feature information such as the device name or the nickname of the controlled intelligent control device is changed, and the user still sends the control instruction to the controlled intelligent control device according to the original feature information, at this time, the changed feature information of the controlled intelligent control device is not matched with the feature information carried in the control instruction triggered by the user, which may cause that the controlled intelligent control device cannot respond to the device control instruction of the master intelligent control device.

Under the condition, in order to facilitate normal and effective communication between the two devices, when the master control intelligent control device does not receive the instruction execution result of the controlled intelligent control device, the master control intelligent control device can send a request to the master control device again to obtain new device information, and newly determine the new controlled intelligent control device capable of executing the current device control instruction, so that normal communication between the master control intelligent control device and the new controlled intelligent control device is realized, and the communication efficiency is ensured.

Specifically, when there is an update in the device information of each device in the local area network, to ensure that the communication is effectively performed, the controller is further configured to perform the following steps:

and 161, after sending the next device control instruction to the controlled intelligent control device based on the communication information, if an instruction execution result returned by the controlled intelligent control device is not received, sending the next device control instruction to the master control device, where the next device control instruction is used to instruct the master control device to query new communication information based on new feature information carried in the next device control instruction.

And step 162, receiving new communication information returned by the master control equipment, wherein the new communication information is used for determining new controlled intelligent control equipment responding to the next equipment control instruction.

After the controlled intelligent control device executes the device control instruction of the main control intelligent control device once, the instruction execution result is returned to the main control intelligent control device, so that the two devices are ensured to have directional communication capability. Therefore, when the master control intelligent control device and the controlled intelligent control device perform single-line directional communication, if the controlled intelligent control device does not send the instruction execution result to the master control intelligent control device, it indicates that the master control intelligent control device cannot send the current device view instruction to the controlled intelligent control device, and the controlled intelligent control device cannot respond to the device control instruction sent by the master control intelligent control device.

Under the circumstance, the master intelligent control device needs to send the currently generated device control instruction to the master control device again, the master control device inquires the device information again based on the characteristic information carried in the current device control instruction, and sends new communication information in the inquired new device information to the master intelligent control device, so that the master intelligent control device can determine a new controlled intelligent control device based on the new communication information and establish new directional communication connection with the new controlled intelligent control device.

For example, after the user sends a primary device control instruction to the controlled intelligent control device "air conditioner in master bedroom" by using the master intelligent control device "refrigerator in kitchen" to control the "air conditioner in master bedroom" to execute the control brake as "on", and then the "refrigerator in kitchen" and the "air conditioner in master bedroom" establish the directional communication connection. And if the characteristic information of the controlled intelligent control equipment is modified by the user later, if the 'air conditioner of the master bedroom' is modified into 'air conditioner of the bedroom', generating new characteristic information.

In this case, the user generates the device control instruction "turn on the air conditioner in the master bedroom" again by using the master intelligent control device, and at this time, the feature information "the air conditioner in the master bedroom" carried in the current device control instruction is inconsistent with the new feature information "the air conditioner in the bedroom" of the current controlled intelligent control device, which results in that the current device control instruction cannot be sent to the original controlled intelligent control device (the new information after changing the feature information is "the air conditioner in the bedroom").

Therefore, the main control intelligent control device needs to send a device control instruction of turning on the air conditioner of the main bedroom to the main control device again, and new device information of each device in the local area network is stored in the main control device. And inquiring corresponding new equipment information by the master control equipment based on the current characteristic information in the current equipment control instruction, and further determining new controlled intelligent control equipment capable of executing the current equipment control instruction based on the new equipment information so as to establish new directional communication connection between the master control intelligent control equipment and the new controlled intelligent control equipment.

In some embodiments, if there is no feature information consistent with the current feature information in each piece of new device information stored in the master control device, the associated feature information may be determined by the foregoing method, so that the user performs secondary interaction to determine new device information, and then determines a new controlled intelligent control device that can execute a current device control instruction, so as to establish a new directional communication connection between the master control intelligent control device and the new controlled intelligent control device. The implementation process of determining the new controlled intelligent control device through the associated characteristic information may refer to the content of steps 121 to 122 in the foregoing embodiment, and is not described herein again.

In some embodiments, when a user generates a device control instruction, if the user is unfamiliar with device information of each intelligent control device, a situation that a control action carried in the device control instruction is inconsistent with a function supported by a corresponding controlled intelligent control device easily occurs, so that the controlled intelligent control device cannot execute the control action in the device control instruction, and normal communication between the master control intelligent control device and the controlled intelligent control device is affected.

In order to ensure normal communication among multiple devices in the local area network, before the master control device sends target communication information of the controlled intelligent control device to the master intelligent control device, whether a target control action carried in a device control instruction sent by the master intelligent control device is consistent with an action which can be executed by the controlled intelligent control device can be judged. If the two pieces of target function information are inconsistent, the master control device can send the target function information of the controlled intelligent control device to the master control intelligent control device in order to ensure that the controlled intelligent control device can execute corresponding actions in time, so that a user can correct and control the actions executed by the controlled intelligent control device in time.

To this end, in the process, the controller is further configured to perform the steps of:

and 171, receiving target function information of the controlled intelligent control equipment, which is returned by the master control equipment when the comparison target control action corresponding function is inconsistent with the externally provided function of the controlled intelligent control equipment, wherein the target function information comprises at least one externally provided function.

And 172, responding to an operation instruction generated by the user on any externally-provided function in the target function information, and generating a new control action based on the operated externally-provided function.

And 173, sending the device control instruction carrying the new control action to the controlled intelligent control device, so that the controlled intelligent control device executes the new control action.

After the master control intelligent control device sends the device control instruction to the master control device, the master control device can search the device information of the controlled intelligent control device based on the target characteristic information carried in the device control instruction. And comparing whether the target control action carried in the equipment control instruction is consistent with the execution action supported by the controlled intelligent control equipment, namely comparing whether the function corresponding to the target control action is consistent with the externally provided function of the controlled intelligent control equipment.

If the function contrast is inconsistent, the control action triggered by the user is indicated, and the controlled intelligent control equipment cannot execute the control action. At this time, the target function information in the device information of the controlled intelligent control device can be sent to the main control intelligent control device for information prompt, so that the user can conveniently determine the control action of the controlled intelligent control device again. The target function information is used for representing the externally provided function of the controlled intelligent control equipment. The manner of information prompt is the same as that provided in the foregoing embodiments, and is not described herein again.

For example, when the information prompting mode adopts an interface display mode, a user operates the main control intelligent control device and selects one of the target function information presented in the user interface to trigger, so as to determine the externally-provided function of the operation and generate a new control action.

And the master control intelligent control equipment regenerates the equipment control instruction based on the new control action and sends the equipment control instruction carrying the new control action to the controlled intelligent control equipment based on the communication information returned by the master control equipment, so that the controlled intelligent control equipment executes the new control action to ensure the normal communication among the multiple equipment in the local area network.

Therefore, according to the intelligent control device provided by the embodiment of the present invention, when the master control intelligent control device executes the multi-device communication method, the device control instruction triggered by the user and used for controlling the controlled intelligent control device is sent to the master control device, and the master control device queries the target communication information of the controlled intelligent control device based on the target characteristic information carried in the device control instruction, and returns the target communication information to the master control intelligent control device. And the master control intelligent control equipment sends the equipment control instruction to the controlled intelligent control equipment based on the target communication information, so that the controlled intelligent control equipment executes the target control action. Therefore, when the controlled intelligent control device is controlled by the master intelligent control device in the same local area network, the master control device which stores the information of each device in the local area network can preferentially respond to the device control instruction of the master intelligent control device and send the inquired communication information of the controlled intelligent control device to the master intelligent control device, so that the directional communication between the master intelligent control device and the controlled intelligent control device is realized. The method can realize the directional communication of a plurality of devices in the local area network, and avoid the interference to other non-relevant devices in the communication process; meanwhile, information leakage is avoided, and safety is improved; the direct form of the information is more beneficial to ensuring the high efficiency of the communication process.

Fig. 10 illustrates another flow diagram of a multi-device communication method according to some embodiments. The intelligent control device provided by the embodiment of the invention is applied to a master control device end for inquiring communication information, and comprises: the device comprises a memory, a first storage and a second storage, wherein the memory is configured to store device information of all intelligent control devices connected with the same local area network, and the device information comprises characteristic information, communication information and function information; a controller connected to the memory, the controller being configured to perform the following steps when executing the multi-device communication method shown in fig. 9 and 10:

and S21, receiving a device control instruction which is sent by the master control intelligent control device and used for controlling the controlled intelligent control device, wherein the device control instruction carries target characteristic information and target control action of the controlled intelligent control device, and the controlled intelligent control device, the master control intelligent control device and the master control device are in the same local area network.

And S22, responding to the device control instruction, and inquiring target communication information of the controlled intelligent control device based on the target characteristic information.

The master control device, the master control intelligent control device and the controlled intelligent control device can be any device in the same local area network, and a user can utilize a device which is close to the master control intelligent control device as the master control intelligent control device and send a device control instruction through the master control intelligent control device so as to control a target controlled intelligent control device to execute corresponding actions.

When a user needs to utilize the master control intelligent control device to control the controlled intelligent control device to execute corresponding actions, a device control instruction is generated by the user through triggering, and the generation mode of the instruction can be a voice mode or a mode of manually triggering the corresponding APP. For a specific implementation process, reference may be made to the content of the foregoing embodiments, which is not described herein again.

The device control instruction generated by the user carries the target characteristic information and the target control action of the controlled intelligent control device, and the master control intelligent control device sends the device control instruction to the master control device. After receiving the device control instruction sent by the master control intelligent control device, the master control device can query the target communication information of the controlled intelligent control device based on the target characteristic information carried in the device control instruction.

When inquiring the target communication information of the controlled intelligent control equipment, the master control equipment matches the target characteristic information carried in the equipment control instruction with the characteristic information in each locally stored equipment information one by one. If the feature information which is matched and consistent with the target feature information exists in the local cache, the fact that the controlled intelligent control device which the user wants to control exists and is online is indicated, and at the moment, the master control intelligent control device can obtain complete device information of the controlled intelligent control device corresponding to the target feature information.

In some embodiments, when the feature information in the local cache is matched with the target feature information carried in the device control instruction, the master control device may also have a condition that matching cannot be performed or unique matching cannot be performed, which may affect normal communication between subsequent devices. For example, the condition that the target controlled intelligent control device cannot be matched means that when a user triggers a device control instruction in a voice mode, target characteristic information carried in the instruction is not standard, so that the master control device cannot query the target controlled intelligent control device during query. The condition that the intelligent control devices cannot be uniquely matched refers to a condition that the names of the intelligent control devices by the users may have duplicate names, so that the master control device cannot accurately determine which controlled intelligent control device needs to be controlled by the users during query.

Specifically, when the general control device does not inquire the target communication information, the controller is further configured to execute the following steps:

and 2211, if the matched and consistent feature information is not inquired based on the target feature information, acquiring the associated feature information associated with the target feature information from all the stored feature information.

And 2212, sending the associated characteristic information to the main control intelligent control equipment for information prompt, wherein the main control intelligent control equipment is used for generating the specified associated characteristic information based on the operation of the user.

And 2213, responding to the query instruction which is sent by the main control intelligent control device and carries the specified associated characteristic information, querying the target communication information of the controlled intelligent control device based on the specified associated characteristic information, and sending the target communication information to the main control intelligent control device.

When the master control device queries the device information of the controlled intelligent control device based on the device control instruction, the master control device is realized by matching target characteristic information in the device control instruction with device information in a local cache, specifically stored characteristic information. The master control device does not inquire the matched unique characteristic information locally, that is, the target characteristic information generated by the user is not standard or normative and cannot be matched with the pre-stored device information.

Therefore, in order to facilitate normal communication of multiple devices in the local area network, the master control device can provide associated characteristic information for the master control intelligent control device, and a user can conveniently perform secondary interaction. In this scenario, the associated feature information is determined based on the target feature information, and the associated feature information is also feature information stored in the master control device.

When the related feature information is determined, the similarity between the target feature information and any one of the stored related information is calculated, and the feature information of which the similarity exceeds a threshold value is taken as the related feature information. If the matched and consistent association information is not inquired, the controlled intelligent control device which the user wants to control does not exist, the user is prompted to select the controlled intelligent control device by determining the association characteristic information so as to facilitate the normal operation of the current device control process.

For example, the target feature information is the device name "master-sleeping air conditioner", and what is stored locally in the general control device is actually "master-sleeping air conditioner 1, master-sleeping air conditioner 2, master-sleeping air conditioner 3", and the like, and at this time, the target feature information cannot be matched with any feature information stored locally. Therefore, the main lying air conditioner 1, the main lying air conditioner 2, and the main lying air conditioner 3 can be used as the associated feature information by calculating the similarity.

After the master control device selects the associated characteristic information, the associated characteristic information can be sent to the master control intelligent control device for information prompt, so that a user can be inquired about which device a device control instruction is specifically sent to. The information prompting mode of the main control intelligent control device for the associated feature information can be a mode of displaying through a display or voice broadcasting, and the specific implementation mode can refer to the content of the foregoing embodiment, which is not repeated here.

And the user performs secondary interaction based on the associated characteristic information presented by the main control intelligent control equipment, selects one of the associated characteristic information as the appointed associated characteristic information, generates a query instruction and sends the query instruction to the main control equipment again. And after receiving the query instruction, the master control equipment queries the target communication information of the controlled intelligent control equipment again based on the specified associated characteristic information.

And the master control equipment sends the secondarily inquired target communication information to the master control intelligent control equipment, and the secondarily inquired target equipment information is the only equipment information of the controlled intelligent control equipment, which can realize equipment communication. And the main control intelligent control equipment receives the target communication information, so that the directional communication with the only controlled intelligent control equipment can be realized.

In some embodiments, when the general control device queries a plurality of target communication information, that is, there is a duplicate name condition, the controller is further configured to perform the following steps:

step 2221, if a plurality of pieces of feature information with consistent matching are found based on the target feature information, sending the plurality of pieces of feature information with consistent matching to the main control intelligent control device for information prompt;

step 2222, in response to the query instruction carrying the designated feature information selected by the user and sent by the master intelligent control device, query the target communication information of the controlled intelligent control device based on the designated feature information, and send the target communication information to the master intelligent control device.

When the master control device queries the device information of the controlled intelligent control device based on the device control instruction, if the master control device queries a plurality of matched and consistent feature information locally, the situation that a user has a duplicate name when naming each intelligent control device in the local area network is explained, so that the master control device cannot determine which specific device information is returned to the master intelligent control device, that is, the controlled intelligent control device cannot be uniquely determined.

Therefore, in order to facilitate normal communication of multiple devices in the local area network, the master control device can provide associated characteristic information for the master control intelligent control device, and a user can conveniently perform secondary interaction. In this scenario, the associated feature information is feature information repeated with the target feature information, and the associated feature information is also feature information stored in the master control device.

The master control device selects the associated characteristic information and then sends the associated characteristic information to the master control intelligent control device, and the master control intelligent control device carries out information prompt on the associated characteristic information sent by the master control device so as to inquire a user to which device a device control instruction is specifically sent. The information prompting mode of the main control intelligent control device for the associated feature information can be a mode of displaying through a display or voice broadcasting, and the specific implementation mode can refer to the content of the foregoing embodiment, which is not repeated here.

And S23, sending the target communication information of the controlled intelligent control device to the main control intelligent control device, so that the main control intelligent control device establishes directional communication connection with the controlled intelligent control device based on the target communication information, and controls the controlled intelligent control device to execute the target control action.

The master control device can return the target device information to the master control intelligent control device after inquiring the target device information of the controlled intelligent control device based on the device control instruction sent by the master control intelligent control device. The data returned by the master control device can be complete device information of the controlled intelligent control device, can also be target communication information for communication, and can be specifically realized based on actual application conditions.

The master control intelligent control device can perform the next control process based on the current state after acquiring the current state of the controlled intelligent control device after executing the device control instruction once, and does not need to send the target communication information again after inquiring the target communication information through the master control device, so that the subsequent single-line contact can be realized, and the communication efficiency is improved.

However, during subsequent single-wire directional communication, if the feature information such as the device name or nickname of the controlled intelligent control device is changed, and the user still sends the control instruction to the controlled intelligent control device according to the original feature information, at this time, the changed feature information of the controlled intelligent control device is not matched with the feature information carried in the control instruction triggered by the user, which may cause that the controlled intelligent control device cannot respond to the device control instruction of the master intelligent control device.

Specifically, when the device information of each device in the local area network is updated, in order to ensure that the communication is effectively performed, the controller in the master control device is further configured to perform the following steps:

and 241, when the main control intelligent control device and the controlled intelligent control device establish directional communication connection and the main control intelligent control device does not receive an instruction execution result returned by the controlled intelligent control device, receiving a next device control instruction which is sent by the main control intelligent control device and used for controlling the controlled intelligent control device.

And 242, inquiring new communication information based on the new characteristic information carried in the next device control instruction, and sending the new communication information to the master control intelligent control device, wherein the new communication information is used for determining a new controlled intelligent control device responding to the next device control instruction.

After the directional communication connection between the master control intelligent control device and the controlled intelligent control device is established based on the foregoing embodiment, after the controlled intelligent control device executes the device control instruction of the master control intelligent control device each time, an instruction execution result is returned to the master control intelligent control device, so as to ensure that the two devices still have directional communication capability.

If the controlled intelligent control device does not send the instruction execution result to the master intelligent control device in the subsequent single-wire communication process (without the process of inquiring communication information by the master control device), the master intelligent control device cannot send the current device watching instruction to the controlled intelligent control device, and the controlled intelligent control device cannot respond to the device control instruction sent by the master intelligent control device.

Under the condition, the master control intelligent control device can send the currently generated device control instruction to the master control device again, the master control device inquires the device information again based on the characteristic information carried in the current device control instruction, and sends the new communication information in the inquired new device information to the master control intelligent control device, so that the master control intelligent control device determines the new controlled intelligent control device based on the new communication information, establishes a new directional communication connection with the new controlled intelligent control device, and the new controlled intelligent control device responds to the new control action carried in the next device control instruction.

To this end, in the process, before performing the transmission of the target communication information of the controlled intelligent control device to the master intelligent control device, the controller is further configured to perform the following steps:

step 251, target function information of the controlled intelligent control device is inquired based on the target characteristic information, wherein the target function information comprises at least one externally-provided function.

And 252, if the comparison between the corresponding function of the target control action and any externally provided function of the controlled intelligent control device is inconsistent, sending target function information of the controlled intelligent control device to the main control intelligent control device for information prompt, wherein the target function information is used for indicating the main control intelligent control device to generate a new control action executable by the controlled intelligent control device based on the operation of the user.

After receiving the device control instruction sent by the master control intelligent control device, the master control device queries the target device information of the controlled intelligent control device in a local cache based on the target characteristic information carried in the instruction. And comparing whether the target control action carried in the equipment control instruction is consistent with the execution action supported by the controlled intelligent control equipment or not based on the target function information in the target equipment information, namely comparing whether the function corresponding to the target control action is consistent with the externally provided function of the controlled intelligent control equipment or not.

If the function contrast is inconsistent, the control action triggered by the user is indicated, and the controlled intelligent control equipment cannot execute the control action. At this time, the target function information in the device information of the controlled intelligent control device can be sent to the main control intelligent control device for information prompt, so that the user can conveniently determine the control action of the controlled intelligent control device again. The target function information is used for representing the externally-provided function of the controlled intelligent control device and indicating the main control intelligent control device to generate a new control action executable by the controlled intelligent control device based on the operation of the user.

The information prompting mode comprises an interface display mode and a voice playing mode, and if the interface display mode is adopted, the target function information is displayed in the user interface. And the user operates the main control intelligent control equipment and selects one of the target function information presented in the user interface to trigger so as to determine the externally-provided function of the operation and generate a new control action. And the master control intelligent control equipment regenerates the equipment control instruction based on the new control action and sends the equipment control instruction carrying the new control action to the controlled intelligent control equipment based on the communication information returned by the master control equipment, so that the controlled intelligent control equipment executes the new control action to ensure the normal communication among the multiple equipment in the local area network.

In some embodiments, when the master control device queries the target device information of the controlled intelligent control device in a local cache based on the target characteristic information carried in the device control instruction sent by the master intelligent control device, the master control device can synchronously send the target function information and the target communication information of the controlled intelligent control device to the master intelligent control device when judging that the function corresponding to the target control action carried in the device control instruction is inconsistent with the externally-provided function of the controlled intelligent control device.

Therefore, when the master control device executes the multi-device communication method, the intelligent control device provided by the embodiment of the invention receives the device control instruction sent by the master intelligent control device, inquires the target communication information of the controlled intelligent control device based on the target characteristic information carried in the device control instruction, and returns the target communication information to the master intelligent control device. And the master control intelligent control equipment sends the equipment control instruction to the controlled intelligent control equipment based on the target communication information, so that the controlled intelligent control equipment executes the target control action. Therefore, when the controlled intelligent control device is controlled by the master intelligent control device in the same local area network, the master control device which stores the information of each device in the local area network can preferentially respond to the device control instruction of the master intelligent control device and send the inquired communication information of the controlled intelligent control device to the master intelligent control device, so that the directional communication between the master intelligent control device and the controlled intelligent control device is realized. The method can realize the directional communication of a plurality of devices in the local area network, and avoid the interference to other non-relevant devices in the communication process; meanwhile, information leakage is avoided, and safety is improved; the direct form of the information is more beneficial to ensuring the high efficiency of the communication process.
