[0042] In order to make the purpose, technical scheme and advantages of the present application clearer, the technical scheme of the present application is described in detail below in conjunction with the accompanying drawings and embodiments. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other implementation methods obtained by ordinary technicians in the field without making creative work belong to the scope of protection of the present application.

[0043] For the linkage and collaborative control between existing devices, it is first necessary to configure the network for the devices through the cloud or local area network, and then edit the properties of each device such as the room (location, name) through the APP (editing device properties is used to better distinguish devices. For example, air conditioners are installed in multiple rooms. By editing device properties, you can intuitively find the devices in the APP for operation), and then select the devices to be linked, linkage execution conditions, linkage devices and execution actions through the APP. For example, if the air conditioner is turned on for cooling and the fan is turned on, you need to specify the air conditioner through the APP, set the execution conditions (turn on for cooling), and then select the linked device (fan), and then configure the execution action (fan on). All these device property editing and linkage configuration operations must be configured by the user through the APP to achieve linkage control. The existing linkage control operation is relatively complicated and the user learning cost is high. Based on this problem, a simple air-conditioning linkage fan control scheme is proposed. The air conditioner and the fan can communicate through the established network and obtain the communication signal strength. The signal strength can be used to preliminarily form a distance relationship network between devices and determine the preliminary room attributes. Then, the voice air conditioner is used for sound detection. When the user controls the fan, the voice air conditioner detects whether there is a buzzing sound and performs near-field detection to verify whether the controlled fan is nearby. If the signal strength and the buzzing sound reach a certain threshold, it is judged that the air conditioner and the fan belong to the same room, thereby automatically realizing the spatial attribute relationship binding between the air conditioner and the fan.

[0044] To solve this problem, refer to Figure 1 , the embodiment of the present application provides a method for linkage control of electrical equipment, including:

[0045] S11: Acquiring a signal strength and a device status of a second electrical device through a first electrical device, where the second electrical device is an electrical device that is communicatively connected to the first electrical device;

[0046] That is, the first electrical device and the second electrical device have communication devices and can send information to each other. In particular, in this application, when the device state of the second electrical device changes, a notification message needs to be sent so that the first electrical device can obtain the change of its device state.

[0047] Specifically, all electrical devices are networked, and when the state of any electrical device changes, a message is sent in the network so that other electrical devices know that their device states have changed after receiving the message.

[0048] In one embodiment, obtaining the device status of the second electrical device through the first electrical device includes:

[0049] The device status of all second electrical devices is obtained through the first electrical device.

[0050] That is, the first electrical device will receive any message sent by other electrical devices indicating a change in device status.

[0051] However, in actual use, the messages sent by the electrical devices are generally in compressed or encrypted form, and need to be parsed (such as decompressed or decrypted) after receiving. If all messages are received, the first electrical device needs to process a large amount of data.

[0052] Therefore, in another embodiment, obtaining the device status of the second electrical device through the first electrical device includes:

[0053] Only the device status of the second electrical device whose signal strength is greater than the second threshold is obtained through the first electrical device. When the signal strength is not greater than the second threshold, it means that the second electrical device is far away from the first electrical device and cannot be in the same space. Therefore, only the device status of the second electrical device whose signal strength is greater than the second threshold is obtained.

[0054] That is, firstly, a group of second electrical devices that may be in the same preset space as the first electrical device are determined based on the signal strength, and then when receiving messages, if the messages with device status changes are not sent by these second electrical devices, they will not be parsed, which greatly reduces the amount of data that the first electrical device needs to process.

[0055] S12: Determine a target second electrical device based on the signal strength and the device state, where the target second electrical device is a second electrical device located in the same preset space as the first electrical device.

[0056] As a preferred implementation of the embodiment of the present application, determining the target second electrical device based on the signal strength and the device state includes: acquiring the collected sound of the preset space where the first electrical device is located; when the device state of the second electrical device changes, if the control sound of the preset space where the first electrical device is located is collected, and the signal strength of the second electrical device is greater than a first threshold, then the second electrical device is used as the target second electrical device. The control sound includes but is not limited to a buzzer sound and a button sound.

[0057] In one embodiment, obtaining the collected sound of the preset space where the first electrical device is located is obtaining the sound of the preset space through the first electrical device, that is, the first electrical device has a voice collection function.

[0058] In another embodiment, the sound of the preset space where the first electrical device is located is obtained by collecting the sound of the preset space where the first electrical device is located through another voice collection device. The other voice collection device is arranged near the first electrical device, that is, the distance between the other voice collection device and the first electrical device is less than a preset value.

[0059] In addition, when the difference between the change time and the collection time is within the preset range, it is determined that when the device state of the second electrical device changes, the control sound of the preset space where the first electrical device is located is collected, the change time is the time when the device state of the second electrical device is obtained to change, and the collection time is the time when the control sound of the preset space where the first electrical device is located is collected. The time when the control sound is collected can be directly determined, that is, the collection time is generally more accurate, and the change time is not the time when the device state of the second electrical device changes directly, but the time when the first electrical device receives the change in the device state of the second electrical device. Therefore, when there is a delay in communication, the collection time may be earlier than the change time, so the difference between the change time and the collection time in this application can be a negative value, which needs to be paid attention to when setting the preset range.

[0060] In actual use, due to various interferences, when the device state of the second electrical device in the same preset space changes, the first electrical device or the sound collection device cannot obtain the control sound. Therefore, if the control sound of the preset space where the first electrical device is located is not collected when the device state of the second electrical device changes, the second electrical device with the largest signal strength is obtained; if the signal strength of the second electrical device with the largest signal strength is greater than the first threshold, the second electrical device with the largest signal strength is used as the target second electrical device.

[0061] In practice, there may be multiple second electrical devices in the same preset space as the first electrical device. However, in order to avoid second electrical devices in other spaces being mistakenly judged as being in the same preset space, the embodiment of the present application only selects a second electrical device with the strongest signal as the target second electrical device.

[0062] S13: Based on the control records of the first electrical device and the target second electrical device, the first electrical device and the target second electrical device are controlled in linkage.

[0063] As a preferred implementation method of the embodiment of the present application, if the number of times the first electrical device and the target second electrical device are turned on at the same time in the control record is greater than the preset number, the target environmental parameters and target control parameters when they are turned on at the same time are obtained, and the target environmental parameters include at least one of the following: turn-on time, indoor ambient temperature, outdoor ambient temperature, indoor and outdoor temperature difference, and the target control parameters include the operation mode and operation parameters of the first electrical device and the second electrical device, as well as the operation duration and indoor temperature change rate of each simultaneous turn-on; wherein, the control record can be a historical control record of the first electrical device and the target second electrical device before the target second electrical device is determined. It can also be a control record of the first electrical device and the target second electrical device after the target second electrical device is determined. Even a combination of the two is used as a control record so that the linkage of the two electrical devices is more in line with user habits.

[0064] When the current environmental parameter is the same as the target environmental parameter, the first electrical device and the second electrical device are controlled according to the target control parameter.

[0065] In one embodiment, when the current environmental parameter is the same as the target environmental parameter, the first electrical device and the second electrical device are directly controlled according to the target control parameter.

[0066] In another embodiment, when the current environmental parameter is the same as the target environmental parameter, a voice message is sent to the user, the voice message being used to suggest the user to perform linkage control on the first electrical device and the target second electrical device;

[0067] After receiving the command from the user to allow linkage control, the first electrical device and the second electrical device are controlled according to the target control parameter.

[0068] It should be noted that one first electrical device can correspond to multiple target second electrical devices at the same time.

[0069] The method for linkage control of electrical equipment provided in the embodiment of the present application first obtains the signal strength and device status of the second electrical equipment through the first electrical equipment, then determines the target second electrical equipment based on the signal strength and device status, and finally performs linkage control on the first electrical equipment and the target second electrical equipment based on the control records of the first electrical equipment and the target second electrical equipment. That is, the present application scheme determines the second electrical equipment in the same preset space as the first electrical equipment through the signal strength and device status of the second electrical equipment obtained by the first electrical equipment, and then automatically performs linkage control based on the control record. The user is not required to manually confirm whether the electrical equipment is in the same space, and manually set the linkage relationship. The user's operating difficulty is greatly reduced and the user experience is improved.

[0070] In order to more clearly illustrate the solution of this application, a specific implementation method is provided below. Figure 2 As shown, 4 air conditioners and 4 fans are set in a house, of which air conditioner 0 and fan 0 are set in the master bedroom, air conditioner 1 and fan 1 are set in the second bedroom, air conditioner 2 and fan 2 are set in another room such as a study. Air conditioner 4 and fan 4 are set in the living room.

[0071] Among them, home appliances such as air conditioners and fans are equipped with wireless communication devices, and the devices can communicate through the wireless communication devices. The wireless communication methods can be WIFI, Bluetooth, etc., and the communication signal strength between devices can be detected. The communication signal strength can be used to judge the distance between devices. The signal strength reduction of devices across normal rooms will be relatively large. The air conditioning equipment is equipped with a language recognition function, which can identify the mechanical button sounds and control feedback buzzers of home appliances locally or in the cloud. It can be further configured with a sound output function and can perform voice broadcasting. Home appliances such as fans can only be configured with basic wireless communication functions, and air conditioners and fans are not required to have voice recognition functions at the same time. The button control sounds can also be detected and recognized by other devices with voice recognition functions.

[0072] Intelligent spatial perception:

[0073] Home appliances such as voice air conditioners and fans can know each other's device types and obtain messages about changes in the status of surrounding devices through wireless communication, and monitor the signal strength between air conditioners and fans. Home appliances with voice recognition functions (such as voice air conditioners) synchronously monitor and identify surrounding sounds. When the status of surrounding fan devices is changed, the voice recognition function of the device is used to capture the surrounding mechanical button sounds or buzzing sounds, which are used for device spatial position perception and judgment based on the preset signal strength and button sound thresholds. The spatial relationship is initially locked by signal strength and combined with the key control sounds emitted by voice detection home appliances to further determine the spatial relationship. For example, when the air conditioner detects the signal strength Twx of a nearby fan, when the fan is turned on, the voice air conditioner detects the change in the fan status and captures the buzzing feedback sound through voice recognition, and its button sound value is Tvx. When the signal strength>Tw and the button sound value>Tv, it is judged that the two home appliances belong to the same room.

[0074] If the voice air conditioner detects that the signal strength of multiple fans is greater than Tw, but no button sound is detected, the one with stronger signal strength is selected, thereby realizing intelligent judgment of the spatial relationship between the two devices. It should be noted that in actual control, multiple fans and air conditioners may be in the same room at this time, but considering that no buzzer feedback sound or button sound is captured, in order to avoid false confirmation, only the fan with the strongest signal strength is regarded as the fan in the same room as the air conditioner.

[0075] Automatic sensing instructions:

[0076] Voice air conditioners, fans and other home appliances can establish network communications through the communication module and monitor the strength of communication signals. At the same time, the voice air conditioner always monitors the detection buzzer and other button control feedback sounds.

[0077] During normal use, each appliance sends wireless network data packets through the communication module. Other appliances can monitor the network communication packets and obtain signal strength. Based on the principle of wireless communication, the signal strength decays as the communication distance increases. Therefore, the distance relationship between the appliances can be preliminarily determined based on the signal strength. Figure 2 For example, when fan 0 sends a network data packet, the signal strength detected by air conditioner 0 is greater than that of air conditioner 1. Similarly, the signal strength detected by air conditioner 1 is greater than that of air conditioner 0. By comparing the signal strengths between devices, it can be preliminarily determined that air conditioner 0 and fan 0 are in the same room, and air conditioner 1 and fan 1 are in the same room, thus forming a room attribute relationship for the devices based on the signal strengths.

[0078] When a user operates a home appliance (such as a fan), the controlled home appliance notifies the outside world of receiving the user's operation through the communication module, so that other home appliances receive the notification and conduct monitoring.

[0079] Other home appliances in the monitoring state can monitor the notification and obtain the communication signal strength to form a distance relationship network; for home appliances with voice (such as voice air conditioners), after monitoring the notification, the voice detection is used to detect whether there is a buzzing feedback sound before and after the notification is received. The voice air conditioner records the detected signal strength as Twx, and the button sound value is Tvx. It should be noted that the button sound is always detected, but when receiving the signal of other devices being controlled, it is checked whether there is a buzzing sound before and after (the time before and after detection is to avoid delays in receiving notification signals). Normal devices will have feedback sounds when they are controlled. Based on this principle, it is judged whether the operated device is nearby. It is assumed that when the device is controlled, the buzzing sound heard at that time is emitted by the device. If it can be clearly heard, it means that the device is nearby.

[0080] The signal strength Twx>Tw is a supplement to the buzz feedback sound recognition detection to determine whether it is nearby, and the accuracy of the judgment is improved by combining the signal strength.

[0081] When the signal strength Twx>Tw detected by the voice air conditioner and the button sound value Tvx>Tv, it is determined that the two electrical appliances belong to the same room.

[0082] In general, it is based on the relationship between signal strength and distance, beep sound detection, and the relationship between sound intensity and distance, to automatically identify the voice air conditioner and fan in the same room and realize the linkage binding relationship between devices.

[0083] Automatic linkage control method:

[0084] Through intelligent space perception, it is judged that after the air conditioner and fan are in the same room, the mode and environmental conditions of the user turning on the air conditioner and fan in succession within T time (turning on the air conditioner and fan at the same time for a short time), such as the current time, indoor ambient temperature, outdoor ambient temperature, indoor and outdoor temperature difference, and the operating time and indoor temperature change rate when they are turned on at the same time, etc. After a period of record learning, if the operating habit of turning on the air conditioner and fan at the same time is detected three times in a row, the next time under similar conditions, the linkage operation will be automatically realized, and the air conditioner linkage fan control will be automatically realized. For example, when the user turns on the air conditioner or fan, it will automatically link the fan or air conditioner adapted to the same space, and The user's operation status is prompted by voice. The voice air conditioner broadcast prompts such as "It is detected that you have turned on the air conditioner and fan at the same time multiple times. Do you want the fan or air conditioner to be automatically turned on for you?" If the user answers "OK" or other positive words that are consistent with automatic linkage, the fan or air conditioner will be automatically adapted and linked for the user, and the linkage control relationship will be strengthened and recorded. After that, according to the user's usage habits, the fan or air conditioner will be automatically turned on when the user turns on the air conditioner or fan, reducing the number of inquiries. Furthermore, the air conditioner and fan will be automatically turned on for the user at the appropriate time. Through gradual progress, a more automatic and intelligent linkage control experience can be achieved.

[0085] by Figure 2 For example:

[0086] exist Figure 2 In the example, air conditioner 0 and fan 0 are in the master bedroom, air conditioner 1 and fan 1 are in the second bedroom, and the others are similar. Taking air conditioner 0, fan 0, air conditioner 1, and fan 1 in the master bedroom and second bedroom as examples, air conditioner 0, fan 0, air conditioner 1, and fan 1 have wireless communication functions and can communicate to obtain each other's home appliance category, signal strength, status and other information and control each other. Figure 2 In the figure, the air conditioner is a voice air conditioner, which can perform sound detection and recognition. According to the relationship between wireless signal strength, distance, and wall shielding reduction, under normal circumstances, air conditioner 0 detects that the signal strength of fan 0 is greater than that of fan 1. Air conditioner 0 prioritizes fan 0 as the object in the same space. Air conditioner 0 prioritizes monitoring whether the state change of fan 0 is accompanied by buzzer feedback sound. If both the signal strength and buzzer sound thresholds are met, it is automatically determined to be in the same space. Normally, according to the reduction of sound signals, the buzzer sound detected by air conditioner 0 should be the strongest.

[0087] After automatically determining the spatial relationship between air conditioner 0 and fan 0, the next step is to identify and learn the user's habits and recognize the usage scenario conditions where the user turns on both the air conditioner and the fan at the same time.

[0088] The device linkage control method provided in the embodiment of the present application automatically determines the spatial relationship between devices and establishes linkage control, significantly reducing the user's learning cost and the tedious process of manual operation. By analyzing the user's usage habits, personalized intelligent linkage control is realized, providing an intelligent and convenient service experience. There is no need for the user to manually edit the device location, linkage relationship and linkage conditions. The signal strength and beep sound detection are used to automatically detect whether the air conditioner and fan are in the same room and determine the spatial linkage relationship. According to the user's historical usage habits and environmental conditions, the linkage control between the air conditioner and the fan is automatically realized.

[0089] Based on the same inventive concept, Figure 3 As shown, the present application also provides an electrical equipment linkage control device 30, comprising:

[0090] A parameter acquisition module 31, configured to acquire a signal strength and a device state of a second electrical device through a first electrical device, wherein the second electrical device is an electrical device that is communicatively connected to the first electrical device;

[0098] When the device state of the second electrical device changes, if the control sound of the preset space where the first electrical device is located is collected and the signal strength of the second electrical device is greater than a first threshold, the second electrical device is used as the target second electrical device.

[0099] It should be noted that when the difference between the change time and the collection time is within a preset range, it is determined that when the device state of the second electrical device changes, the control sound of the preset space where the first electrical device is located is collected, and the change time is the time when the device state of the second electrical device is obtained to change, and the collection time is the time when the control sound of the preset space where the first electrical device is located is collected.

[0102] The device linkage control module 33 is used to perform linkage control on the first electrical device and the target second electrical device based on the control records of the first electrical device and the target second electrical device.

[0103] As a preferred implementation method of the embodiment of the present application, if the number of times the first electrical device and the target second electrical device are turned on simultaneously in the control record is greater than a preset number, the target environmental parameters and target control parameters when they are turned on simultaneously are obtained, and the target environmental parameters include at least one of the following: turn-on time, indoor ambient temperature, outdoor ambient temperature, and indoor and outdoor temperature difference; the target control parameters include the operation mode and operation parameters of the first electrical device and the second electrical device, as well as the operation duration and indoor temperature change rate of each simultaneous turn-on;

[0104] When the current environmental parameter is the same as the target environmental parameter, the first electrical device and the second electrical device are controlled according to the target control parameter.

[0106] After receiving the command from the user to allow linkage control, the first electrical device and the second electrical device are controlled according to the target control parameter.
