Fig. 6 is a schematic diagram of a bluetooth Mesh network structure constructed based on a display device according to the present application. In the technical solution provided in the present application, the display device 200 may further form a wireless Mesh network based on a bluetooth function together with the plurality of bluetooth Mesh devices 400, that is, a bluetooth Mesh network. In the bluetooth Mesh network, the display device 200 may be used as a control device to control the bluetooth Mesh device 400 on each node in the network by means of bluetooth connection, such as controlling the bluetooth Mesh device 400 to be turned on and off and controlling other operation parameters of the device.

In this application, the bluetooth Mesh device 400 refers to a device pre-installed with a bluetooth Mesh component, for example, an intelligent home device with a bluetooth function includes an illumination device, a cleaning device, a cooking device, an environmental control device, and the like. It should be noted that, for traditional bluetooth devices such as bluetooth headsets and bluetooth speakers, in the present application, the bluetooth Mesh device 400 can not only transmit data through bluetooth wireless connection, but also form a network through bluetooth connection, thereby implementing mutual free communication between arbitrary devices, and transmitting different instructions through the formed network, so as to control the bluetooth Mesh device 400 on each node.

For example, the display device 200 may form a bluetooth Mesh network with bluetooth Mesh lighting devices distributed in a plurality of rooms. These bluetooth Mesh lighting devices can be uniformly managed and controlled in the display device 200. The bluetooth Mesh lighting in the kitchen may be turned off, e.g. by operation on the display device 200. The corresponding actual operation process is as follows: the user inputs voice to turn off the kitchen lamp through the built-in intelligent voice system of the display device 200, the intelligent voice system converts the input voice into a control instruction, and the control instruction is sent to the Bluetooth Mesh lighting device in the kitchen through the Bluetooth Mesh network.

Obviously, the user can also control the devices in the bluetooth Mesh network in other ways. For example, as shown in fig. 7, interaction in the operation interface of the display device 200 may be performed by the control apparatus 100, and the device list interface may be entered by selecting "bluetooth-bluetooth network". As shown in fig. 8, in the device list interface, all device names and statuses of the bluetooth Mesh network may be presented. The user selects the option corresponding to the kitchen bluetooth Mesh lighting device in the device list through the up, down, left and right keys and the OK key of the control device 100, selects the close option in the pop-up dialog box, and inputs a control instruction. In the same way, the display device 200 sends the control command to the bluetooth Mesh lighting device in the kitchen through the bluetooth Mesh network.

The user may also start the operation control application through the interaction between the control apparatus 100 and the display device 200 through the smart home control application installed on the display device 200, such as apps "comedy share home", "mijia", "smart home", and the like. In the control application, the device list interface may also be displayed for the user to select, generate a corresponding control instruction, and the control display device 200 may send the control instruction to the bluetooth Mesh lighting device in the kitchen through the bluetooth Mesh network by using the program executed by the control application.

As can be seen, in the above control process, the display device 200 may send a control instruction to each bluetooth Mesh device 400 through the bluetooth Mesh network, and control each bluetooth Mesh device 400 to adjust an operation parameter, that is, change the state of the bluetooth Mesh device 400. Generally, the state of the bluetooth Mesh device 400 may include various situations, such as an on/off state, a switching state, etc., according to the type of device. The on/off-line state refers to whether the current bluetooth Mesh device 400 is connected in the bluetooth Mesh network, for example, when the bluetooth Mesh device 400 is powered off (or not powered on), the on/off-line state of the bluetooth Mesh device 400 is off-line; when the bluetooth Mesh device 400 is powered on and has accessed to the bluetooth Mesh network, the on/off-line state of the bluetooth Mesh device 400 is online. The bluetooth Mesh device 400 in the off-line state cannot be controlled through the bluetooth Mesh network in general.

The switch state is a state in which the bluetooth Mesh device 400 is used for representing an operation condition, and if the switch state of the bluetooth Mesh device 400 is on, it indicates that the bluetooth Mesh device 400 is in the operation state; if the switching state of the bluetooth Mesh device 400 is off, it indicates that the bluetooth Mesh device 400 is in a standby state. For example, when the lighting device with bluetooth Mesh is turned on, it indicates that the lighting device is currently on. In practical applications, the on-off state of the bluetooth Mesh device 400 can be controlled through the bluetooth Mesh network no matter whether the bluetooth Mesh device is turned on or turned off. For example, the turning on and off of light fixtures in the kitchen is remotely controlled through the display device 200.

It should be noted that the states of the bluetooth Mesh device 400 are not limited to the above two states, and may have a plurality of states according to the type of the bluetooth Mesh device 400. For example, for an air conditioner with bluetooth Mesh function, the state may include states other than on/off state and on/off state, such as cooling state, heating state, ventilation state, timing on/off state, and the like. These states can be presented, updated and controlled in the device list interface to accommodate different bluetooth Mesh devices 400.

In practical applications, the bluetooth Mesh device 400 is controlled by the display device 200 as an independent device, and may be controlled by other methods. For example, the control is performed by a control switch of the bluetooth Mesh device 400 itself, a remote controller, and a smart terminal device paired therewith. Under different control modes, the state of the bluetooth Mesh device 400 is changed, so that the state of the bluetooth Mesh device 400 is changed in real time. If the bluetooth Mesh device 400 is controlled through the bluetooth Mesh network, the current state of the bluetooth Mesh device 400, that is, the current state, must be obtained first. In order to display and modify the state of the bluetooth Mesh device 400, the display device 200 may display and update the state of the bluetooth Mesh device 400 at a device list interface.

In order to update the state of the bluetooth Mesh device 400, in practical applications, the bluetooth Mesh device 400 may be configured to send a heartbeat message to the display device 200, so as to send the current state of the bluetooth Mesh device 400 to the display device 200 in the form of the heartbeat message. In general, if the display apparatus 200 can receive a heartbeat message transmitted from the bluetooth Mesh apparatus 400, it is interpreted that the bluetooth Mesh apparatus 400 is in an online state. The switching state of the bluetooth Mesh device 400 can be determined according to the content of the sent heartbeat message; similarly, if the display device 200 does not receive the heartbeat message sent by the bluetooth Mesh device 400 for a long time, it indicates that the bluetooth Mesh device 400 is currently in an offline state.

For example, a lighting device located in a kitchen may send a heartbeat message to the display device 200 every 40s after accessing a bluetooth Mesh network. If the lighting device is illuminated, the switch state is on is included in the heartbeat message. The display device 200 may display and update the extracted state in the device list interface by receiving the heartbeat message and parsing and extracting the switch state therein.

If the user controls the lighting device to be turned on or off through the bluetooth Mesh switch in the kitchen, the display device 200 may remotely control the on/off state of the bluetooth Mesh switch, or the user may manually control the on/off state of the bluetooth Mesh switch. Therefore, when the user turns off the lighting device through the switch button, the bluetooth Mesh switch can still send the heartbeat message to the display device 200, that is, the bluetooth Mesh switch is still in the online state, but the actual bluetooth Mesh switch is turned off, and the corresponding device switch state is turned off, so that the display device 200 cannot update the state of the lighting device in time.

In order to update the status of the bluetooth Mesh device 400 in time, as shown in fig. 9a and 9b, the present application provides a bluetooth Mesh device status updating method, which may be configured in the controller 250 of the display device 200, and specifically includes the following steps:

s1: and receiving a switching-in command input by a user and used for switching in the equipment list interface.

The cut-in command refers to a command for entering the device list interface, and a user may perform corresponding interactive operation input through the control device 100, the intelligent voice system, and the mobile terminal. For example, if the control apparatus 100 performs interaction in the operation interface of the display device 200, as shown in fig. 7, and enters the device list interface by selecting "bluetooth-bluetooth network", as shown in fig. 8, the display device 200 receives a switch-in command for switching into the device list interface upon receiving the interaction performed by the user.

Obviously, the cut-in command may be manually input by the user or automatically input by the controller 250 by executing some specific judgment rule. For example, in order to achieve energy saving and emission reduction, the display device 200 may scan the states of the lighting devices in the bluetooth Mesh network by performing a detection procedure in order to turn off unnecessary lighting devices during a part of a period (e.g., day, midnight, or early morning). In the process of executing the detection program, the display device 200 needs to obtain the current status of each lighting device in the bluetooth Mesh network, so that the cut-in command can be automatically generated.

S2: and responding to the hand-in command, and sending a polling command to the Bluetooth Mesh device.

After receiving the cut-in command, the controller 250 of the display device 200 may control the display 275 to display a device list interface for the user to select and perform an interactive operation; on the other hand, in response to the hand-in command, a polling command is sent to the bluetooth Mesh device 400, and the polling command is used for detecting the current state of the bluetooth Mesh device through polling.

Polling is an interactive mode between a control device (display device 200) and a bluetooth Mesh device on a node in a bluetooth Mesh network. The polling is typically initiated by the control device and propagated to each node in the bluetooth Mesh network, where the bluetooth Mesh device 400 feeds back the specified service content based on the inquiry. After the feedback is finished, an inquiry is initiated to the bluetooth Mesh device 400 on the next node, and the process is circulated so that all nodes can feed back the service content.

In the present application, the status of the device may be actively detected by polling the display device 200. For example, the controller 250 transmits a polling command through the bluetooth Mesh network, and performs polling. The bluetooth Mesh device can receive the polling command if the on/off-line state of the bluetooth Mesh device 400 is on-line. The bluetooth Mesh device 400 that receives the polling instruction may feed back the current status to the display device 200 for the polling instruction, including: online and open.

S3: and comparing the current state with the original state of the Bluetooth Mesh equipment.

After receiving the current state fed back by each bluetooth Mesh device 400, the controller 250 of the display device 200 may further compare the current state and the original state of each bluetooth Mesh device 400 to determine whether the state of the bluetooth Mesh device 400 changes.

Wherein the original state is the last state of the bluetooth Mesh device 400 in the device list interface. The device list interface can include all device names forming the current bluetooth Mesh network and the device state when the last heartbeat message is reported. Therefore, through the device list interface, the last state of the bluetooth Mesh device 400 can be acquired. For example, when the heartbeat message is fed back last time, the state of the bluetooth Mesh device 400 is online and off, and the original state is online and off.

Obviously, the original state and the current state may include various types according to the state display condition of the device list interface in actual application. For example, an original on/off-line state and a current on/off-line state based on the on/off-line state; an original switch state based on the switch state and a current switch state. In practice, any state of the bluetooth Mesh device 400 includes an original state and a current state.

S4: and if the current state is different from the original state, updating the original state in the equipment list interface to the current state.

After acquiring the original state and the current state, the controller 250 may further compare the original state and the current state to determine whether the state of the bluetooth Mesh device 400 changes. The specific comparison method may encode the state of the bluetooth Mesh device 400 according to a specified encoding rule, and represent the state in the form of a state value. The controller 250 may determine whether the current state is changed from the original state by comparing the state values. For example, when the switch state value fed back by the bluetooth Mesh device 400 is equal to 1, it represents that the switch state is on. If the switch state value obtained from the device list interface is equal to 0, that is, the switch state is off, it is determined that the current state is different from the original state.

If the current state is different from the original state, it represents that the state of the current bluetooth Mesh device 400 needs to be updated, and thus the original state in the device list interface may be updated to the current state. Namely, in the device list interface, the original state is replaced by the current state, and the updating is completed. Therefore, the method for updating the state of the bluetooth Mesh device 400 provided by the application can actively monitor the state of the bluetooth Mesh device 400 in a polling mode when a user switches into the device list interface, and update the state of the bluetooth Mesh device 400 in time.

In one implementation, the on/off-line status for the bluetooth Mesh device 400 may be directly obtained through a heartbeat message sent by the bluetooth Mesh device 400, that is, the status of the bluetooth Mesh device includes the on/off-line status; as shown in fig. 10, the method further includes:

s101: receiving a heartbeat message sent by the Bluetooth Mesh equipment within a preset timeout period;

s102: if the heartbeat message is received, determining that the current on/off-line state of the Bluetooth Mesh equipment is on-line;

s103: and if the heartbeat message is not received, determining that the current on/off-line state of the Bluetooth Mesh equipment is off-line.

In practical applications, since the bluetooth Mesh device 400 in the bluetooth Mesh network may send a heartbeat message to the display device 200 every predetermined time interval to update its status. It is possible to determine whether the bluetooth Mesh device 400 is online by judging the transceiving of the heartbeat message. For example, the bluetooth Mesh device 400 on each node transmits a heartbeat message to the display device 200 every 40s, that is, the display device 200 may receive a heartbeat message transmitted by the same node device every 40s, thereby maintaining its online status. If the time interval from the last reception of the heartbeat message exceeds 40s and the heartbeat message has not yet been received, the corresponding bluetooth Mesh device 400 is highly likely to have gone offline, and its on/off-line status is updated to offline.

There may be a delay in the time when the heartbeat message is received by the display apparatus 200, considering the influence of network delay, network capacity, and parallel processing speed of the controller 250. Therefore, the timeout time can be preset, and the heartbeat message sent by the bluetooth Mesh device 400 can be received within the preset timeout time. Obviously, the preset timeout is longer than the interval between the transmission of the heartbeat messages by the bluetooth Mesh device 400. For example, the preset timeout time may be set to 140s, that is, if the display apparatus 200 does not acquire a heartbeat message within 140s, it is determined that the current on/off-line state of the bluetooth Mesh apparatus 400 is off-line.

In one implementation, if the current on/off state of the bluetooth Mesh device 400 is online, the on/off state of the bluetooth Mesh device 400 may also be detected, that is, the state of the bluetooth Mesh device 400 also includes the on/off state; as shown in fig. 11, if the heartbeat message is received, the method further includes:

s201: receiving polling result data fed back by the Bluetooth Mesh equipment;

s202: extracting the current on-off state of the Bluetooth Mesh equipment from the polling result data;

s203: and acquiring the original switch state of the Bluetooth Mesh equipment in the equipment list interface.

After the controller 250 transmits the polling command, the bluetooth Mesh device 400 may feed back the current status to the display device 200 and form polling result data. The controller 250, upon receiving the polling result data, may extract the current switching state of each bluetooth Mesh device 400 therefrom. Meanwhile, the controller 250 may also obtain the original switch state of the bluetooth Mesh device 400 in the device list interface, so as to compare the original switch state and determine whether the switch state needs to be updated.

In one implementation, after obtaining the current on-off state and the original on-off state, the current on-off state and the original on-off state may be compared to determine whether the bluetooth Mesh device 400 needs to be updated. If the update is needed, the switch state in the device list interface is updated to the corresponding switch state, and therefore, as shown in fig. 12, the method further includes:

s301: if the current switch state is on and the original switch state is off, updating the switch state of the Bluetooth Mesh device in the device list interface to be on;

s302: and if the current switch state is closed and the original switch state is opened, updating the switch state of the Bluetooth Mesh equipment in the equipment list interface to be closed.

In practical application, for convenience of data transmission, processing and analysis, the polling result data and the heartbeat message in the application can be kept as the same type of data. Therefore, while the current on/off state of the bluetooth Mesh device 400 is actively detected through the polling command, the current on/off state of the bluetooth Mesh device 400 can also be detected. If the current on/off state and the on/off state of a certain bluetooth Mesh device 400 are not acquired in the polling result data, it is determined that the bluetooth Mesh device 400 is in the off-line state.

That is, as shown in fig. 13, in one implementation, the method further includes:

s401: acquiring the original on/off-line state of the Bluetooth Mesh device in the device list interface;

s402: if the original on/off-line state is off-line and the current on/off-line state is on-line, updating the on/off-line state of the Bluetooth Mesh device in the device list interface to be on-line;

s403: and if the original on/off-line state is on-line and the current on/off-line state is off-line, updating the on/off-line state of the Bluetooth Mesh device in the device list interface to be off-line.

In one implementation, as shown in fig. 14, the step of sending a polling command to the bluetooth Mesh device in response to the hand-in command includes:

s211: setting a polling flag to true;

s212: and if the heartbeat message sent by the Bluetooth Mesh equipment is received within the preset timeout period, sending a polling instruction to the Bluetooth Mesh equipment.

In practice, when the user switches into the device list interface, the controller 250 of the display device 200 may set the flag of whether the round robin is required to true. That is, the controller 250 may transmit a polling instruction to the bluetooth Mesh device 400. And then determines when to send a polling command to the bluetooth Mesh device 400 by detecting the condition of the heartbeat message sent by the bluetooth Mesh device 400. Since the bluetooth Mesh device 400 must have a heartbeat message in the power-on scene of the added device, if the heartbeat message is received, it is determined that the bluetooth Mesh device 400 is in an online state, and accordingly, the on-off state of the bluetooth Mesh device 400 can be actively detected, that is, a polling instruction is sent to the bluetooth Mesh device 400.

Obviously, in this embodiment, the polling instruction is sent when it is determined that the bluetooth Mesh device 400 is in the online state, so that the sent polling instruction can only be directed to the bluetooth Mesh device 400 in the online state. Therefore, the number of polling nodes can be reduced, the polling time is shortened, and polling result data can be formed when part of the nodes cannot respond, so that the polling efficiency and the success rate are improved.

In one implementation, as shown in fig. 15, the method further includes:

s501: receiving a switching-out instruction input by a user and used for switching out a device list interface;

s502: and responding to the cut-in command, setting a polling mark to false, and stopping sending a polling command to the Bluetooth Mesh device.

If the user cuts out of the device list interface, it typically means that the user is no longer actively controlling the bluetooth Mesh device 400. At this time, the timeliness requirement for the status update of the bluetooth Mesh device 400 is not high, and thus when the user cuts out the device list interface, the polling operation for the bluetooth Mesh device 400 may be stopped. That is, the controller 250 sets the polling flag to false and stops transmitting the polling command to the bluetooth Mesh device 400 after receiving a switch-out command for switching out the device list interface input by the user.

According to the technical scheme, the first aspect of the application provides a bluetooth Mesh device state updating method, which is applied to a display device 200, and the method firstly receives an instruction for switching into a device list interface; then sending a polling instruction to the bluetooth Mesh device 400 to detect the current state of the bluetooth Mesh device 400 in a polling mode; then comparing the current state with the original state of the bluetooth Mesh device 400; and when the current state is different from the original state, updating the original state in the equipment list interface to the current state. When the method switches to the device list interface, the status update mechanism of the Bluetooth Mesh device 400 status is obtained by polling through heartbeat messages, and the problem that the device status cannot be updated in time is solved.

Based on the above method for updating the status of the bluetooth Mesh device, the present application also provides a method for updating the status of the bluetooth Mesh device, which is applied to the bluetooth Mesh device, and as shown in fig. 16, the method includes:

s601: receiving a polling instruction sent by display equipment;

s602: in response to the polling instruction, performing polling to obtain a current state;

s603: and sending the current state to the display equipment through a heartbeat message.

In the application, the device with the bluetooth Mesh component can cooperate with the display device 200 to perform data interaction, so that the current state of the device can be sent to the display device 200 through the bluetooth Mesh network to perform state updating. Since the display device 200 serves as a control device of the bluetooth Mesh network, when the status of the bluetooth Mesh device 400 is updated on the display device 200, it is equivalent to that the status update is completed on the entire bluetooth Mesh network.

Accordingly, the controller of the bluetooth Mesh device 400 may be configured to transmit a heartbeat message to the display device 200 at a preset time interval and receive a polling instruction transmitted by the display device 200. Wherein the polling instruction is an instruction sent by the display device in response to switching into a device list interface. After receiving the polling command, the polling operation may be performed according to the polling command, and the current status may be fed back to the display apparatus 200. The feedback of the current state can also be accomplished by means of heartbeat messages.

For example, after receiving the polling command, the bluetooth Mesh device 400 detects that the current switch state of the bluetooth Mesh device is on, and then feeds back data that the switch state is on to the display device 200. And generating the switching state data into data in the same heartbeat message form, wherein the state value corresponding to the switching state in the fed back data is 1. The bluetooth Mesh device 400 transmits the generated data to the display device 200 through the bluetooth Mesh network so that the display device 200 performs status update.

As can be seen from the foregoing technical solutions, the second aspect of the present application provides a bluetooth Mesh device status updating method, which is applied to the bluetooth Mesh device 400. After receiving the polling instruction sent by the display device 200, the bluetooth Mesh device 400 performs polling to obtain the current state, and sends the current state to the display device 200 through a heartbeat message, so that the display device 200 can update the state of the bluetooth Mesh device 400 in the device list interface when the state of the bluetooth Mesh device changes.

Based on the bluetooth Mesh device status updating method, the application also provides a display device, which includes: a display 275, a bluetooth module 232, and a controller 250.

Wherein the display 275 is configured to display a device list interface; the bluetooth module 232 is configured to establish a bluetooth Mesh network with a bluetooth Mesh device;

as shown in fig. 9a, 9b, the controller 250 is configured to perform the following program steps:

s1: receiving a switching-in command input by a user and used for switching in a device list interface;

s2: responding to the cut-in command, and sending a polling command to the Bluetooth Mesh device; the polling instruction is used for detecting the current state of the Bluetooth Mesh equipment through polling;
