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, at least one application program runs in the application program layer, and the application programs may be windows (windows) programs carried by an operating system, system setting programs, clock programs or the like; or an application developed by a third party developer. In particular implementations, the application packages in the application layer are not limited to the above examples.

The framework layer provides an Application Programming Interface (API) and a programming framework for the application program of the application layer. The application framework layer includes a number of predefined functions. The application framework layer acts as a processing center that decides to let the applications in the application layer act. The application program can access the resources in the system and obtain the services of the system in execution through the API interface.

As shown in fig. 4, the core layer includes at least one of the following drivers: audio drive, display driver, bluetooth drive, camera drive, WIFI drive, USB drive, HDMI drive, sensor drive (like fingerprint sensor, temperature sensor, pressure sensor etc.) and power drive etc..

Based on the display device, the display device can support the rotating and/or lifting functions by adding the driving component and the gesture detection component. Typically, the driving assembly includes a rotation assembly and/or a lifting assembly, and the controller 250 may be in communication with the rotation assembly and/or the lifting assembly to control the rotation assembly to rotate the display when the display needs to be rotated and to control the lifting assembly to lift or lower the display when the display needs to be lifted or lowered.

In a possible implementation manner, a GPIO interface is provided on the rotation component and/or the lifting component, and the controller changes the state of the GPIO interface of the rotation component and/or the lifting component by reading the GPIO interface. And the rotating component and/or the lifting component drive the display to rotate and/or lift according to the changed GPIO interface state when the GPIO interface state changes.

In a possible implementation, the lifting assembly and/or the lifting assembly includes an MCU chip on which a bluetooth module is integrated, such that the lifting assembly and/or the lifting assembly supports bluetooth functionality, such as Bluetooth Low Energy (BLE), and further, the controller 250 may communicate with the lifting assembly and/or the lifting assembly based on a bluetooth protocol.

In some embodiments, the detection assembly includes a sensor for detecting a rotational state of the display and a sensor for detecting a lifting state of the display. In the rotating or lifting process of the display, the controller monitors the rotating state or the lifting state of the display in real time according to the data detected by the gesture detection assembly. For example, in the process of controlling the display to rotate, information such as a rotation angle, an angular speed and the like is acquired by monitoring data of the sensor. In the process of controlling the display to ascend and descend, information such as ascending and descending distance and ascending and descending speed is acquired by monitoring data of the sensor.

In some embodiments, the detection assembly is included in the drive assembly. For example, a sensor for detecting a rotation state of the display is included in the rotating member, and constitutes the rotating member together with the above-described rotating member. The sensor for detecting and displaying the lifting state is included in the lifting assembly, and the sensor and the lifting assembly form the lifting assembly together.

In some embodiments, the rotating assembly is referred to as a rotary drive device and the lifting assembly is referred to as a lifting drive device.

In some embodiments, the rotating assembly and the lifting assembly together form a driving device, i.e., the driving device has both functions of driving the display to rotate and lift.

Fig. 5 is a schematic rear view of a display device shown in some exemplary embodiments of the present application, and as shown in fig. 5, the display device includes a display 260 and a lifting driving device 511. The lifting driving device 511 and the lifting guide rail 512, the lifting guide rail is fixed on the bracket 512. The rotation drive is then arranged inside the elevation drive, i.e. between the elevation drive and the display, not shown in fig. 5.

In some embodiments, a rotary lifting control system is deployed in an operating system of a display device, and the rotary lifting control system may be deployed at an application framework layer or across layers, for example, a part of function codes is deployed at the application framework layer, and another part of function codes is deployed at a runtime library layer. The rotational elevation control system may be in communication with the drive assembly and the detection assembly to provide uniform, coordinated, and safe control of the rotation and elevation of the display device.

During specific implementation, the same control interface provided for each application through the rotary lifting control system comprises a unique control inlet, such as clockwise rotation, anticlockwise rotation, rotation stop, short-distance lifting, long-distance lifting and stopping lifting, so that the lifting operation and the rotary operation are prevented from being carried out simultaneously, and the safety of rotary lifting control is ensured. In addition, the rotary lifting control system performs unified logic processing and judgment on control instructions issued by each application. For example, before controlling the rotation, it is necessary to determine whether the rotation is in the process of ascending and descending, and if not, the rotation is controlled again. When the rotation is started, each application is notified through broadcasting, and the application is guaranteed to receive the same notification information. In the rotation control process, the monitoring sensor detects big data to obtain information such as a rotation angle, an angular speed and the like and update parameters, and the parameter information can be fed back to each application. The system performs rotation completion detection once every preset time (e.g., 200ms), and sends a broadcast notification application when rotation is completed.

Fig. 6 is an application scenario shown in some exemplary embodiments of the present application, and the application scenario may be a simple schematic of a shopping mall. As shown in fig. 6, in this scenario, there are a plurality of smart tvs with a lifting function, and each smart tv is equipped with at least one lifting driving device for driving the screen of the smart tv to lift. It should be understood that in this scenario, the bluetooth broadcast information is continuously sent to the outside when the smart tv is powered on and is not connected to the lifting driving device of the smart tv, so that the smart tv can discover itself after scanning is started. In such implementation scenarios, after the bluetooth module of a certain smart television starts scanning, a plurality of lifting driving devices of the same type and/or identification can be scanned, wherein the lifting driving devices comprise lifting driving devices matched with the smart television and lifting driving devices matched with other smart televisions in the environment.

For the application scenario, the display device provided in the embodiment of the present application may determine, from a plurality of driving devices with the same name or type, a target driving device having a mechanical connection relationship with itself, and establish a communication connection with the target driving device, so that connection to an incorrect driving device may be avoided. In addition, if the user replaces the driving device of the display device, after the replacement is completed, the Bluetooth switch of the display device is turned off and turned on again, so that the pairing and connection process of the new driving device can be triggered, additional user operation is not needed, and the user experience is good.

In some embodiments, the controller 250 turns on the bluetooth module in response to the bluetooth switch turn-on command. For example, in the case where the bluetooth switch is turned off, the user displays an interface of a setting application by operating the control display device, and inputs a bluetooth switch-on instruction by operating the bluetooth switch button in the interface including the bluetooth switch button provided by the setting application. For another example, in the case that the bluetooth switch is turned off, the user inputs a voice password using a far-field voice or near-field voice control function of the display device to input a bluetooth switch turn-on instruction. In another example, the setup application sends a bluetooth switch on instruction to the bluetooth module in response to a power-on broadcast generated when the display device is powered on. After the Bluetooth module is started, the driving device is scanned through the Bluetooth module according to the preset device identification. The driving device can be a rotation driving device, a lifting driving device or a driving device integrating rotation and lifting functions. The preset device identification may be a device name of the drive device or a universally unique identification code UUID. When a plurality of driving devices are scanned according to preset device identifications, a target driving device is determined from the plurality of driving devices. When one driving device is scanned according to the preset device identification, the driving device is determined as a target driving device. The target driving device refers to a driving device which is only one of the plurality of scanned driving devices and has a mechanical connection relationship with the display device which initiates the scanning. It should be understood that the display device can be rotated and lifted under the mechanical driving action of the driving device only when the driving device and the display device have a mechanical connection relationship. For example, when a plurality of rotation driving devices are scanned according to preset device identifications corresponding to the rotation driving devices, a target rotation driving device mechanically connected with the display device is determined from the plurality of rotation driving devices; and when the plurality of lifting driving devices are scanned according to the preset device identification corresponding to the lifting driving device, determining a target lifting driving device mechanically connected with the display device from the plurality of lifting driving devices. After the target driving device is determined, communication connection is established with the target driving device, so that when rotation or lifting is required to be controlled, the target driving device is controlled to drive the display to rotate or lift based on the communication connection with the target driving device. For example, when the display is required to be controlled to ascend and descend, the target ascending and descending driving device is controlled to drive the display to ascend and descend based on the communication connection with the target ascending and descending driving device, and when the display is required to be controlled to rotate, the target rotating driving device is controlled to drive the display to rotate based on the communication connection with the target rotating driving device.

In specific implementation, when the controller detects that the bluetooth switch is turned on, a scanning instruction is sent to the bluetooth module, and the scanning instruction comprises a preset device identifier. And after the Bluetooth module receives the scanning instruction, starting scanning. It should be understood that, after the bluetooth module starts scanning, it may receive bluetooth broadcast information sent by the external device, where the bluetooth broadcast information includes data such as device identifier, media access control address, rssi (received Signal Strength indication) value, and the like. The Bluetooth module matches the device identification of the external device with a preset device identification, and determines whether the scanned external device is a driving device. For example, the external device whose device identifier matches the first preset device identifier is determined as the lifting driving device, and the external device whose device identifier matches the second preset device identifier is determined as the rotating driving device. The device identifier is matched with the preset device identifier, including but not limited to the case where the device identifier is the same as the preset device identifier. Therefore, the display equipment can filter other external equipment according to the preset equipment identification, and only keeps the scanning result of the lifting driving equipment or the rotating driving equipment.

In some embodiments, a user may enter a media access control address (MAC address for short) of a target drive device in a setup application. The display equipment receives the MAC address of the target driving equipment input by a user and judges whether the MAC address of the target driving equipment is stored in the configuration file or not. And if the MAC address of the target drive equipment is stored in the configuration file, replacing the MAC address stored in the configuration file by using the MAC address input by the user latest. And if the MAC address of the target drive equipment is not stored in the configuration file, generating configuration information of the target drive equipment in the configuration file according to the MAC address input by the user latest.

Fig. 7 is an interface provided by a setup application, which may be an interface triggered by a user clicking a setup key or a menu key on a remote control, according to some embodiments of the present application. As shown in fig. 7, a plurality of setting items, namely setting items 701 and 705 respectively, are displayed in the interface, wherein the setting item 701 is a setting item corresponding to the rotation up-down control. The user can set the rotary elevation control function by operating the setting item 701. Illustratively, when the user operates the setting item 701, a setting interface of the rotation up-down control function is displayed.

Fig. 8 is an interface provided by a setting application in some embodiments of the present application, which may be specifically a setting interface of a rotary elevation control function entered after a user operates a setting item 701 while the interface shown in fig. 7 is displayed. As shown in fig. 8, an item 801 for adding a rotation driving device and an item 802 for adding a lifting driving device are displayed in the interface. The user can input the MAC address of the target rotation driving device through the operation item 801, and can input the MAC address of the target elevation driving device through the operation item 802. Illustratively, when the user operates the item 801, a MAC address input interface corresponding to the rotation driving apparatus is displayed. When the user operates the item 802, a MAC address input interface corresponding to the lifting drive device is displayed. The user can input the MAC address of the target rotation driving device in the MAC address input interface corresponding to the rotation driving device, and input the MAC address of the target lifting driving device in the MAC address input interface corresponding to the lifting driving device.

Fig. 9 is an interface provided by a setting application in some embodiments of the present application, which may be specifically a MAC address input interface entered after a user operates a setting item 801 when the interface shown in fig. 8 is displayed. The user may enter the MAC address of the target rotary drive device in the interface. The display device receives the MAC address of the target rotary driving device input by the user, generates target driving device configuration information in a configuration file, or updates the previously generated target driving device configuration information.

Based on the above embodiments, in some implementations of determining a target driving device, when the display device scans multiple driving devices, the MAC address of each driving device is compared with the MAC address in the configuration information of the target driving device in the configuration file, and a driving device with a MAC address consistent with the MAC address of the target driving device, which is obtained in advance, in the multiple driving devices is determined as the target driving device. For example, when the display device scans a plurality of rotation driving devices, the MAC address of each rotation driving device is compared with the MAC address of the target rotation driving device in the target driving device configuration information, and the rotation driving device whose MAC address coincides with the MAC address of the target rotation driving device acquired in advance is determined as the target rotation driving device. When the display device scans a plurality of lifting driving devices, comparing the MAC address of each lifting driving device with the MAC address of the target lifting driving device in the configuration information of the target driving device, and determining the lifting driving device with the MAC address consistent with the MAC address of the target lifting driving device obtained in advance as the target lifting driving device.

In this way, when there are a plurality of driving devices of the same type and/or the same identification in the environment where the display device is located, the target driving device matching the display device can be determined from the plurality of driving devices according to the MAC address of the target driving device obtained in advance, so as to prevent the display device from being connected to other driving devices. The display device is matched with a display device mechanical structure, or has a mechanical connection relation with the display device.

In other embodiments, in some embodiments, the controller 250 turns on the bluetooth module in response to a bluetooth switch turn-on command. And after the Bluetooth module is started, scanning the driving equipment through the Bluetooth module according to the preset equipment identification and the MAC address of the target driving equipment acquired in advance. The driving device can be a rotation driving device, a lifting driving device or a driving device integrating rotation and lifting functions. The scanned driving device is determined as a target driving device. And establishing communication connection with the target driving device, so that the target driving device can be controlled to drive the display to rotate or ascend and descend based on the communication connection with the target driving device when rotation or ascending and descending are required to be controlled.

In specific implementation, when the controller detects that the bluetooth switch is turned on, a scan instruction is sent to the bluetooth module, and the scan instruction includes a preset device identifier and an MAC address of a target drive device. And after the Bluetooth module receives the scanning instruction, starting scanning. It should be understood that, after the bluetooth module starts scanning, it may receive bluetooth broadcast information sent by the external device, where the bluetooth broadcast information includes data such as device identifier, media access control address, rssi (received Signal Strength indication) value, and the like. The Bluetooth module firstly matches the device identification of the external device with the preset device identification, and determines whether the scanned external device is a driving device. For example, the external device whose device identifier matches the first preset device identifier is determined as the lifting driving device, and the external device whose device identifier matches the second preset device identifier is determined as the rotating driving device. Then, the bluetooth module matches the MAC address of the scanned driving device with the MAC address of the target driving device in the scan instruction, and determines the driving device with the MAC address consistent with the MAC address of the target driving device among the plurality of driving devices as the target driving device. Finally, the bluetooth module reports the information of the target driver to the controller 250. And the controller establishes communication connection with the target driving equipment according to the information reported by the Bluetooth module. Therefore, the Bluetooth can filter out other external equipment and other driving equipment according to the preset equipment identification and the MAC address of the target driving equipment, and only the target driving equipment matched with the display equipment is reserved.

In other implementations of determining the target driving device, the display device screens out the target driving device from the plurality of driving devices according to the scanned signal strength of the driving device, so as to prevent the display device from being connected to other driving devices, for example, when the bluetooth module scans the plurality of lifting driving devices according to the first preset device identifier, the target lifting driving device is determined according to the signal strength of each lifting driving device. And when the Bluetooth module scans a plurality of rotary driving devices according to the second preset device identification, determining a target rotary driving device according to the signal intensity of each rotary driving device.

In one possible implementation, the drive device with the highest signal strength is determined as the target drive device. For example, the signal strength of the lift drive device may be evaluated based on an average of RSSI values of the lift drive device over a period of time, and the signal strength of the swing drive device may be evaluated based on an average of RSSI values of the swing drive device over a period of time.

Illustratively, if the bluetooth module scans a plurality of lifting drive devices according to preset device identifiers, the scanning is continued, so that a plurality of preset RSSI values of each lifting drive device are obtained by continuously receiving bluetooth broadcast information sent by the plurality of lifting drive devices. After the preset plurality of RSSI values are acquired for each lifting driving device, the Bluetooth module closes scanning, and feeds back the scanned device information of each lifting driving device and the preset plurality of RSSI values of each lifting driving device to the controller. And the controller calculates the RSSI average value of each lifting driving device according to the preset RSSI values of each lifting driving device, and determines the lifting driving device with the maximum RSSI average value as the target lifting driving device.

It should be understood that if the bluetooth module scans multiple rotation driving devices according to preset device identifiers, the rotation driving device with the highest signal strength may be selected from the multiple rotation driving devices as the target rotation driving device according to the manner of determining the target lifting driving device described in the above example.

In some embodiments, to further improve the accuracy of determining the target driving device, after determining a driving device with the highest signal strength among a plurality of driving devices, determining whether the signal strength of the driving device is greater than a preset value, and if the signal strength of the driving device is greater than the preset value, determining the driving device as the target driving device. The preset value may be determined according to the working signal strength of the target driving device when the target driving device is applied to the display device, that is, according to the signal strength scanned by the display device when the target driving device is installed in the display device.

With the foregoing example, after the controller determines the lifting driving device with the largest RSSI average value, it determines whether the RSSI average value is greater than the RSSI average value preset by the target lifting driving device. And if the RSSI average value is larger than the RSSI average value preset by the target lifting driving equipment, determining the lifting driving equipment as the target lifting driving equipment.

In this way, when there are a plurality of driving devices of the same type and/or the same identification in the environment where the display device is located, the target driving device matching the display device can be determined from the plurality of driving devices according to the MAC address of the target driving device obtained in advance, so as to prevent the display device from being connected to other driving devices.

In some embodiments, Bluetooth Low Energy (BLE) connectivity is established over the GATT protocol, with GATT-based communication between the display device and the rotation drive device and/or the elevation drive device. The GATT is known as Generic Attribute Profile, which may be translated into "Generic Attribute protocol", referring to the general specification of sending and receiving very short pieces of data, referred to as attributes (attributes), over a bluetooth connection. The GATT defines that two BLE devices communicate through Service (Service) and Characteristic value (characteristics). The characteristic value may be understood as a label, and the desired content may be obtained or written through the label. The Service deploys the BLE slaves, each Service represents one capability of the BLE slaves, such as power information Service, system information Service and the like, each Service comprises a plurality of characteristic values, and each specific characteristic value is a subject of BLE communication. For example, the current power amount is 80%, and the charateristic characteristic value of the current lighting passing power amount is stored in the profile of the slave, so that the master can read that the current power amount is 80% through the charateristic characteristic value of the power amount.

It is noted that, in the GATT protocol, both the Service (Service) and the feature value (characteriodic) of the BLE slave device need the universally unique identifier UUID of the BLE slave device for identification, so that the BLE slave device needs to open the UUID Service if two BLE devices are to establish a GATT connection. Based on this, in the process of scanning the rotation driving device and/or the lifting driving device, after determining that the scanned external device is the rotation driving device or the lifting driving device, it is further required to determine whether each rotation driving device or each lifting driving device opens the UUID service, so as to filter out the rotation driving devices or the lifting driving devices that do not open the UUID service, and determine the target driving device from the rotation driving devices or the lifting driving devices that open the UUID service.

In some embodiments, after determining the target drive device, the controller 250 establishes a GATT communication connection with the target drive device to control the target drive device to drive the display to ascend or descend based on the GATT communication connection. In a specific implementation, the controller 250 first pairs with the target driver, and if the pairing is successful, establishes a GATT communication connection with the target driver based on a GATT procedure. And if the pairing is failed or the GATT communication connection is failed, scanning the rotary driving device or the lifting driving device again according to the preset device identification, and executing the subsequent steps according to the scanning result.

The rotary lifting control system serves as a GATT client, and the rotary driving device and the lifting driving device serve as GATT servers. When a switch of the Bluetooth module of the display device is turned on, the rotary lifting control system performs Bluetooth pairing with the rotary driving device and the lifting driving device, and after the Bluetooth pairing is successful, GATT communication connection is established between the rotary lifting control system and the rotary driving device and between the rotary lifting control system and the lifting driving device. After connection is successful, the rotary lifting control system serves as a GATT client, the state, position, fault and other information of the rotary driving device and the lifting driving device serving as a GATT server can be inquired regularly, and meanwhile when the rotary driving device or the lifting driving device breaks down or is lifted to a limit switch, the state can be actively fed back to the rotary lifting control system, so that each application can be guaranteed to read the latest lifting state.

It should be noted that in a network topology based on the GATT protocol, one BLE master device (also referred to as a central device) may connect to multiple BLE slave devices (also referred to as peripheral devices), and one BLE slave device may only connect to one BLE master device. It should be understood that, in this application, after the display device establishes GATT communication connection with the target driver device, the display device is a BLE master device, and the target driver device is a BLE slave device. And when the target driving device is successfully connected with the display device, the Bluetooth broadcast information is stopped being sent to the outside.

It should be further noted that the two parties communicating based on the GATT are in a C/S relationship, where the peripheral device serves as a GATT server and defines service and characteristics. The central device acts as a GATT client and initiates a request to the server. It should be noted that all communication events are initiated by the client and the response of the receiving server is implemented. It should be understood that, in the present application, after the display device establishes the GATT communication connection with the target driver device, the display device serves as a GATT client, and initiates a request to the server, for example, a request for periodically querying information such as a rotation lifting state, a position, and a fault of the target driver device; and the target drive equipment serves as a GATT server and returns a response to the client.

As can be seen from the foregoing embodiments, based on the display device provided in the embodiments of the present application, when there are multiple driving devices of the same type and/or the same identifier in an environment where the display device is located, a target driving device that is configured with the display device can be screened from the multiple driving devices, so as to prevent the display device from being connected to other driving devices. In addition, if the user replaces the driving device of the display device, after the replacement is completed, the Bluetooth switch of the display device is turned off and turned on again, and then the pairing and connection process of the new driving device can be triggered.

And the preset RSSI value is determined according to the RSSI value of the target driving equipment during working.
