[0135] Figure 3 Schematically shows a configuration block diagram of the control device 100 according to an exemplary embodiment. Figure 3 As shown, the control device 100 includes a controller 110, a communication interface 130, a user input / output interface, a memory, and a power supply.

[0136] The control device 100 is configured to control the display device 200, and can receive the user's input operation instructions, and convert the operation instructions into instructions that the display device 200 can recognize and respond to, playing the role of an interactive intermediary between the user and the display device 200. For example, the user operates the channel increase and decrease keys on the control device 100, and the display device 200 responds to the channel increase and decrease operations.

[0137] In some embodiments, the control device 100 may be a smart device, for example, the control device 100 may be installed with various applications for controlling the display device 200 according to user needs.

[0138] In some embodiments, Figure 1 As shown, the mobile terminal 300 or other smart electronic device can play a similar function to the control device 100 after installing the application for controlling the display device 200. For example, the user can install the application to realize the function of the physical button of the control device 100 through various function keys or virtual buttons of the graphical user interface provided on the mobile terminal 300 or other smart electronic device.

[0139] The controller 110 includes a processor 112, a RAM 113, a ROM 114, a communication interface 130, and a communication bus. The controller is used to control the operation and operation of the control device 100, as well as the communication and cooperation between the internal components and the external and internal data processing functions.

[0140] The communication interface 130, under the control of the controller 110, realizes the communication of control signals and data signals with the display device 200. For example, the received user input signal is sent to the display device 200. The communication interface 130 may include at least one of other near field communication modules such as a WiFi chip 131, a Bluetooth module 132, and an NFC module 133.

[0141] The user input / output interface 140 includes at least one of other input interfaces such as a microphone 141, a touch panel 142, a sensor 143, and a button 144. For example, the user can input user commands through voice, touch, gesture, pressing, and other actions. The input interface converts the received analog signal into a digital signal, and the digital signal into a corresponding command signal, and sends it to the display device 200.

[0142] The output interface includes an interface for sending received user commands to the display device 200. In some embodiments, it can be an infrared interface or a radio frequency interface. For example, in the case of an infrared signal interface, the user input command needs to be converted into an infrared control signal according to an infrared control protocol, and then sent to the display device 200 via an infrared sending module. For another example, in the case of a radio frequency signal interface, the user input command needs to be converted into a digital signal, and then modulated according to a radio frequency control signal modulation protocol, and then sent to the display device 200 by a radio frequency sending terminal.

[0143] In some embodiments, the control device 100 includes at least one of a communication interface 130 and an input / output interface 140. The control device 100 is configured with a communication interface 130, such as a WiFi, Bluetooth, NFC or other module, which can encode the user input command through the WiFi protocol, Bluetooth protocol, or NFC protocol and send it to the display device 200.

[0144] The memory 190 is used to store various operating programs, data and applications for driving and controlling the control device 200 under the control of the controller. The memory 190 can store various control signal instructions input by the user.

[0145] The power supply 180 is used to provide operating power support for each component of the control device 100 under the control of the controller, and can be a battery and related control circuits.

[0146] In some embodiments, the system may include a kernel, a command parser (shell), a file system, and an application. The kernel, shell, and file system together form the basic operating system structure, which allows users to manage files, run programs, and use the system. After power-on, the kernel starts, activates the kernel space, abstracts hardware, initializes hardware parameters, etc., runs and maintains virtual memory, schedulers, signals, and inter-process communication (IPC). After the kernel starts, the shell and user applications are loaded. After startup, the application is compiled into machine code to form a process.

[0147] See also Figure 4 In some embodiments, the system is divided into four layers, from top to bottom, namely, the application layer (Applications) layer (referred to as "application layer"), the application framework layer (Application Framework) layer (referred to as "framework layer"), the Android runtime (Android runtime) and system library layer (referred to as "system runtime library layer"), and the kernel layer.

[0148] In some embodiments, at least one application is running in the application layer, and these applications may be window programs, system settings programs, clock programs, camera applications, etc. provided by the operating system; or they may be applications developed by third-party developers, such as hi-view programs, karaoke programs, magic mirror programs, etc. In specific implementation, the application packages in the application layer are not limited to the above examples, and may actually include other application packages, which are not limited in the embodiments of the present application.

[0149] The framework layer provides application programming interfaces (APIs) and programming frameworks for applications in the application layer. The application framework layer includes some predefined functions. The application framework layer is equivalent to a processing center that determines the actions that applications in the application layer take. Applications can access system resources and obtain system services during execution through the API interface.

[0150] like Figure 4 As shown, in the embodiment of the present application, the application framework layer includes managers, content providers, etc., wherein the manager includes at least one of the following modules: an activity manager (ActivityManager) is used to interact with all activities running in the system; a location manager (Location Manager) is used to provide system services or applications with access to system location services; a package manager (Package Manager) is used to retrieve various information related to the application package currently installed on the device; a notification manager (NotificationManager) is used to control the display and clearing of notification messages; a window manager (Window Manager) is used to manage icons, windows, toolbars, wallpapers, and desktop components on the user interface.

[0151] In some embodiments, the activity manager is used to manage the life cycle of each application and the usual navigation back function, such as controlling the exit of the application (including switching the user interface currently displayed in the display window to the system desktop), opening, and backing (including switching the user interface currently displayed in the display window to the parent user interface of the currently displayed user interface), etc.

[0152] In some embodiments, the window manager is used to manage all window programs, such as obtaining the display size, determining whether there is a status bar, locking the screen, capturing the screen, controlling display window changes (for example, shrinking the display window, shaking the display, distorting the display, etc.), etc.

[0153] In some embodiments, the system runtime layer provides support for the upper layer, namely the framework layer. When the framework layer is used, the Android operating system will run the C / C++ library contained in the system runtime layer to implement the functions to be implemented by the framework layer.

[0154] In some embodiments, the kernel layer is a layer between hardware and software. Figure 4As shown, the kernel layer includes at least one of the following drivers: audio driver, display driver, Bluetooth driver, camera driver, WIFI driver, USB driver, HDMI driver, sensor driver (such as fingerprint sensor, temperature sensor, touch sensor, pressure sensor, etc.), etc.

[0155] In some embodiments, the core layer further includes a power driver module for performing power management.

[0156] In some embodiments, Figure 4 The software programs and / or modules corresponding to the software architecture in Figure 2 or Figure 3 In the first memory or the second memory shown.

[0157] In some embodiments, taking the magic mirror application (photographing application) as an example, when the remote control receiving device receives the input operation of the remote control, the corresponding hardware interrupt is sent to the kernel layer. The kernel layer processes the input operation into a raw input event (including the value of the input operation, the timestamp of the input operation, and other information). The raw input event is stored in the kernel layer. The application framework layer obtains the raw input event from the kernel layer, identifies the control corresponding to the input event according to the current position of the focus, and the input operation is a confirmation operation, and the control corresponding to the confirmation operation is the control of the magic mirror application icon. The magic mirror application calls the interface of the application framework layer to start the magic mirror application, and then starts the camera driver by calling the kernel layer to realize the capture of static images or videos through the camera.

[0158] In some embodiments, for a display device with a touch function, taking a split-screen operation as an example, the display device receives an input operation (such as a split-screen operation) performed by a user on the display screen, and the kernel layer can generate a corresponding input event according to the input operation, and report the event to the application framework layer. The activity manager of the application framework layer sets the window mode (such as a multi-window mode) and the window position and size corresponding to the input operation. The window management of the application framework layer draws the window according to the settings of the activity manager, and then sends the drawn window data to the display driver of the kernel layer, and the display driver displays the corresponding application interface in different display areas of the display screen.

[0159] In some embodiments, Figure 5 As shown in , the application layer includes at least one application that can display a corresponding icon control in the display, such as: a live TV application icon control, a video on demand application icon control, a media center application icon control, an application center icon control, a game application icon control, etc.

[0160] In some embodiments, the live TV application can provide live TV through different signal sources. For example, the live TV application can use input from cable TV, wireless broadcast, satellite service, or other types of live TV services to provide TV signals. And, the live TV application can display video of the live TV signal on the display device 200.

[0161] In some embodiments, the video on demand application can provide videos from different storage sources. Unlike the live TV application, the video on demand provides video display from certain storage sources. For example, the video on demand can come from the server side of the cloud storage, from the local hard disk storage containing the stored video programs.

[0162] In some embodiments, the media center application can provide an application for playing various multimedia contents. For example, the media center can be a service provided by a user to access various images or audios through the media center application, which is different from live TV or video on demand.

[0163] In some embodiments, the application center can provide and store various applications. The application can be a game, an application, or some other application related to a computer system or other device but can be run on a smart TV. The application center can obtain these applications from different sources, store them in a local storage, and then run them on the display device 200.

[0164] The above-mentioned part in the embodiment can be the common part of the patent document of television software, especially the supplementary description of the part related to the invention point according to the invention creation. The relevant part of the department can also be appropriately deleted.

[0165] Take remote control as an example. If all remote controls are equipped with alkaline batteries or lithium-ion batteries, based on the 480 million households in China, each household needs two remote controls, each remote control needs two batteries, and each remote control needs to replace the battery once a year, which means 3.84 billion batteries will be consumed each year. Therefore, if the use of batteries can be reduced, it will make a huge contribution to the ecological environment.

[0166] In the related art, solar energy is used to charge the battery to extend the battery life, but this does not remove the battery in the remote control. In the related art, a laser remote control is also used, but it also needs to be equipped with a battery for power supply.

[0167] Based on the above problems, an embodiment of the present application provides a control device, which further reduces the power consumption of the control device by adjusting the power of sending control information to the display device, thereby extending the life of the battery in the control device, reducing the frequency of battery replacement in the control device, and reducing environmental pollution.

[0168] Reference Figure 6 , is a structural block diagram of a control device according to an embodiment of the present application. Specifically, Figure 3 On the basis of the above, the control device 100 also includes: a super capacitor 115, a solar panel 116 and / or a USB charging circuit 117; the processor 112 includes: a power management module 1121, and the power management module 1121 is used to manage the solar panel 116 and / or the USB charging circuit 117 to charge the super capacitor 115.

[0169] In addition, refer to Figure 6 The control device 100 further includes a crystal oscillator 118 , which specifically includes a 16 MHz crystal oscillator and a 32.768 MHz crystal oscillator. The crystal oscillator 118 is connected to the controller 110 .

[0170] Among them, the embodiment of the present application uses a supercapacitor to replace the battery in the control device, which can reduce the use of batteries. Furthermore, the use of solar panels can use daily light sources such as LED light sources and sunlight light sources to charge the supercapacitor, and the use of a USB charging circuit can charge the supercapacitor when the control device needs fast charging.

[0171] Specifically, both weak LED light sources and sunlight (daylight sources) can charge supercapacitors. Exemplarily, the operating voltage of the control device needs to be above 1.65V, or 30uW of energy is required to meet the normal operation of the control device. When the control device is working, through the management of the power management module, the operating level of the control device can be between 1.0V-1.8V, and the protection voltage is set at 3.3V. Referring to Table 1, the charging current of the supercapacitor under different light intensities under different light sources when the supercapacitor is 2.2V in actual tests. Referring to Table 2, the charging current of the supercapacitor under different light intensities under different light sources when the supercapacitor is 2.8V in actual tests. From Tables 1 and 2, it can be seen that the LED light source can be charged slowly, and the daylight light source can be charged quickly when the light intensity is high. And when the voltage of the supercapacitor is larger, the charging current is lower under the same light intensity.

[0177]

[0178] Reference Figure 7 The USB charging circuit 117 includes: a USB basic charging circuit 1171 and a Schottky barrier diode 1172 , the anode of the Schottky barrier diode 1172 is connected to the USB basic charging circuit 1171 , and the cathode of the Schottky barrier diode 1172 is connected to the power management module 1121 .

[0179] The USB basic charging circuit 1171 includes: a USB controller K1, a resistor R1, a resistor R2, a resistor R3, a capacitor R1, a capacitor R2, a Schottky barrier diode D1, a Schottky barrier diode D2 and a voltage converter U. Figure 7 The GND in it is ground.

[0180] In an embodiment of the present application, a Type-A USB, Type-B USB or Type-C USB charging head can be used to charge the supercapacitor. Among them, the voltage converter U is a voltage converter for 5V to 3.3V. The 3.3V voltage output by the voltage converter U is connected to the power management module through the Schottky barrier diode 1172, and the supercapacitor is connected through the power management module to quickly charge the supercapacitor. Among them, adding the Schottky barrier diode 1172 can prevent the current of the supercapacitor from leaking to the voltage converter U through the resistor R3, which will increase the power consumption of the control device. Adding the Schottky barrier diode 1172 can avoid the occurrence of this leakage and reduce power consumption.

[0181] For example, in experimental tests, when only the USB basic charging circuit 1171 is provided (without adding the Schottky barrier diode 1172), the key power consumption of the control device is 83.99uA. When the Schottky barrier diode 1172 is added, the key power consumption of the control device is 49.34uA, which greatly reduces the power consumption of the control device.

[0182] Among them, the Schottky diode is made using the metal-semiconductor (MS) contact effect. Since the current transport of the metal-semiconductor contact mainly relies on majority carriers (electrons), its electron mobility is high, and the MS junction can be precisely manufactured and processed at the sub-micron scale, so that the Schottky barrier diode can be used in the submillimeter wave and terahertz wave bands. The main parameters that characterize the electrical characteristics of the Schottky barrier diode are forward conduction voltage, reverse leakage current density and breakdown voltage. When the control device is not in the charging state, the control device is powered by the negative electrode (3.3V voltage) of the Schottky barrier diode. Usually, when the Schottky barrier diode is at 10V, the leakage current of the Schottky barrier diode is 1uA. When the Schottky barrier diode is at 3.3V, the reverse leakage current of the Schottky barrier diode is 200nA-300nA.

[0183] In addition, when the control device is in the charging state, it is charged with 5V through USB, and passes through a low-power LDO (the end of resistor R1 away from resistor R2). The static power consumption of this LDO is 1.5uA, which can ensure that the output will not lose too much energy. And the LDO pin level is 1.8V, and the current is 20uA, which keeps the control device working normally while minimizing the loss. After the LDO outputs 3.3V, it passes through the Schottky barrier diode 1172, with a forward voltage drop of 0.3V, and the output voltage is about 3V, ensuring the normal operation of the control device.

[0184] Reference Figure 8 , is a circuit diagram of the power management module 1121, wherein the power management module 1121 includes: a controller K2, a capacitor C3 (10uF), a capacitor C4 (220uF), a capacitor C5 (10uF), and an inductor L. Among them, capacitors C4 and C5 are connected to super capacitors and connected to controller K2, and capacitors C49 and C5 are used for filtering. In addition, pin VDDIOP supplies power to pins VDDIO and VDDIOA, and the voltage is 1.8V. Pins VDDIO and VDDIOA are mainly used to supply power to the IO circuits of the digital and analog units. Pin AVDD1 P supplies power to pin VDD1A, and the voltage is 1V. Pin DVDD1 P supplies power to pin DVDD1, and the voltage is 1V. Pins VDD1A and DVDD1 are mainly used to supply power to digital and analog power supplies, and AUX is powered by power supply, and the voltage is 3.3V. The INP in-phase terminal and the INN reverse terminal are respectively connected to the processor to supply power to the processor.

[0185] Reference Fig. 9 , is a flowchart of a method for controlling a device to send information, the method for sending information is applied to a processor of a control device, and specifically includes the following steps:

[0186] S901, using preset power to send first control information to a display device.

[0187] In the related art, after a button is pressed, the control device uses a fixed power to send control information to the display device. In order to ensure the communication distance, the fixed power is the maximum power that the control device can transmit, such as 4dBm. Under this fixed power, the communication distance between the control device and the display device is the maximum. For example, for Bluetooth communication, the communication distance can reach 20 meters. This communication distance has great redundancy for the display device.

[0188] Therefore, in the embodiment of the present application, when the control device is awakened from sleep mode by a button, the preset power is used to send the first control information to the display device. The preset power may be the maximum power that the control device can reach. The first control information may be the control information corresponding to any button on the control device.

[0189] In addition, the preset power may also be the target power sent by the display device last time, and the setting method of the preset power is not limited here.

[0190] In an embodiment of the present application, the control device may send the first control information to the display device via Bluetooth or infrared.

[0191] S902: Receive target power sent by a display device.

[0192] The target power is determined by the display device according to the signal strength of the first control information received, the target power has a negative correlation with the signal strength, and the target power is less than the preset power.

[0193] In the embodiment of the present application, when the control device sends the first control information to the display device, the display device receives the first control information and determines the signal strength corresponding to the received first control information. The corresponding relationship between the signal strength and the target power can be pre-stored.

[0194] Exemplarily, referring to Table 3, the stronger the signal strength of the received first control information, the more redundancy in determining the preset power, and thus the smaller the target power can be set. Therefore, the target power has a negative correlation with the signal strength. In addition, the target power has a level, and the target power level can be set to level 1, level 2, level 3, and level 4 according to the target power from large to small.

[0195] Table 3

[0196]

[0197] In the embodiment of the present application, the correspondence shown in Table 3 can be stored, and when the display device receives the first control information, the target power corresponding to the signal strength can be determined according to the pre-stored correspondence. In addition, the number of target power levels, signal strength and target power shown in Table 3 only show the logical relationship of their correspondence, not the optimal use case, and can be adjusted according to actual conditions during use.

[0198] In addition, the display device sends the target power to the control device via Bluetooth.

[0199] In an embodiment of the present application, if the preset power is the target power sent by the display device last time, then when the preset power is small, the signal strength of the first control information determined by the display device is small, and the target power sent to the control device can be greater than the preset power, and then the target power of the second control information sent by the control device can be dynamically adjusted. The control device does not need to always send control information to the display device at maximum power, thereby reducing the power consumption of the control device.

[0200] S903: Use the target power to send second control information to the display device.

[0201] In the embodiment of the present application, the control device may also use Bluetooth or infrared to send the second control information to the display device.

[0202] In addition, the control device can use the target power to send the second control information to the display device, and the target power can be less than the preset power, thereby reducing the power consumption of the control device. The embodiment of the present application uses the above method to determine the target power, which can greatly reduce the power consumption of the control when the control device uses Bluetooth to interact with the display device in voice mode and social mode.

[0203] Reference Fig.10 ,exist Fig. 9 On the basis of, the method for controlling the device to send information also includes the following steps:

[0204] S101, determining a current working mode of a control device.

[0205] In the embodiment of the present application, the working modes of the control device include: sleep mode, fast charging mode, standby mode, key mode, voice mode, headphone mode and social mode. Among them, the control device can determine the current working mode of the control device according to the current use of the control device.

[0206] S102, according to the current working mode, control the corresponding hardware to be in working state.

[0207] In the embodiment of the present application, the hardware of the control device includes: USB charging circuit, solar panel, super capacitor, power management module, Bluetooth module, infrared function module, main control function module, remote control antenna, infrared transmitting tube, crystal oscillator, buttons, headphones, microphone, etc.

[0208] Among them, the working mode of the control device has a corresponding relationship with the working state of the hardware.

[0209] Referring to Table 4, which shows the correspondence between the working mode of the control device and the working state of the hardware, it can be seen that in the embodiment of the present application, in the current working mode, only the corresponding hardware needs to work, and other unnecessary hardware is turned off, which can further reduce the power consumption of the control device. In Table 4, the solar charging panel is only turned off in the fast charging mode, and the other working modes are all working states, and the supercapacitor is turned on in any working mode. In addition, except for the corresponding hardware in the working state, the other hardware is in the off state.

[0210] Specifically, in Table 4, the sleep mode refers to a state in which the control device is not in use, that is, no data processing is required. At this time, the processor can control the solar panel, power management module and super capacitor to work, and other hardware is turned off. The solar panel charges the super capacitor through the power management module. The fast charging mode uses the USB charging circuit to quickly charge the super capacitor. At this time, the processor can control the USB charging circuit, power management module, and super capacitor to work, and other hardware are turned off. The standby mode is a mode of waiting to receive data input by the user through buttons or voice. Therefore, the main control function module needs to work to process the input data, the Bluetooth module needs to work to receive data or send data, and the power management module and solar panel need to work to charge. The key mode includes when the electronic device is turned on for the first time (receiving the user's key operation on the power-on button of the control device), only the main control function module and the infrared function module are required to receive the information corresponding to the user's key operation for the first time, and send control information to the infrared function module, so that the infrared function module sends an infrared signal to the display device. Then, after the power-on is completed, only the main control function module and the Bluetooth module work, and other hardware are turned off. The main control function module is used to process the received key information, and then the control information needs to be sent to the display device through the Bluetooth module. In voice mode, the user's voice needs to be collected through a microphone, and then the control information corresponding to the voice is sent to the display device through the Bluetooth module. In headphone mode, the voice information sent by the display device is received through the Bluetooth module and played through the headphones. The social mode is the process in which the user communicates with the display device through the control device, so a microphone is required to collect the user's voice information, send it to the display device through the Bluetooth module, receive the voice information sent by the display device through the Bluetooth module, and play it through the headphones.

[0211] In the embodiment of the present application, other working modes of the control device can also be set according to actual needs. In different working modes, only the corresponding hardware needs to work, and other hardware can be in a turned off state, thereby further reducing the power consumption of the control device.

[0212] Table 4

[0213]

[0214] S103, responding to the sleep instruction sent by the display device and entering the sleep mode.

[0215] The sleep instruction is sent by the display device according to the current display state, and the current display state indicates that the display device will not receive the control information sent by the control device within a preset time.

[0216] In the related art, the control device enters sleep mode only when the standby time exceeds a certain time, such as 5 seconds, and no operation is performed. The control device cannot determine the time when the user stops the operation.

[0217] In an embodiment of the present application, the display device can determine to send a sleep command to the control device based on the current display state. After receiving the sleep command, the control device can enter the sleep mode without waiting for a certain period of time, thereby further reducing the power consumption of the control device.

[0218] Exemplarily, the current display state is after the input is completed in the TV text box and the cursor is moved to the confirmation and clicked. The current display state can also be after a certain video is selected in the video application and the video playback frame is maximized.

[0219] In the embodiment of the present application, firstly, the power consumption of the control device can be reduced by determining the target power. Secondly, the working state of the corresponding hardware is determined by the current working mode of the control device, thereby further reducing the power consumption of the control device. In addition, a sleep instruction is sent to the control device by the current display state of the display device, so that the control device enters the sleep state in time, thereby further reducing the power consumption of the control device.

[0220] Reference Fig.11 , is a flowchart of a method for receiving information provided by an embodiment of the present application, which is applied to Figure 2 The display device shown in the figure includes a processor. The processor is configured to execute Fig.11 The information receiving method shown in the figure specifically comprises the following steps:

[0221] S111, receiving first control information sent by a control device using a preset power.

[0222] Among them, refer to Fig.12 , is a diagram of the data format of control information. The control information includes: header, payload and MIC (substantial control information), where header is 16 bytes, payload is 27 bytes, and MIC is 32 bytes. Fig.12 In the example, the control device sends three control messages (121, 122, and 123) to the display device. The display device can read the header each time and determine that the header and the header after the header and the header before the next header are a control message.

[0229] After receiving the second control information, the display device may also determine a new target power according to the signal strength of the second control information, and send the target power to the control device so that the control device adjusts the power of sending the control information again.

[0230] In an embodiment of the present application, the display device can determine the corresponding target power based on the signal strength of the received first control information and send it to the control device, so that the control device adjusts the power of sending the control information, thereby reducing the power consumption of the control device.

[0231] Reference Fig.13 ,exist Fig.11 Based on the above, the method for receiving information by the display device further includes the following steps:

[0232] S131, determining the current display state of the display device.

[0233] Among them, the current display state of the display device can be any display state of the display device, such as the display state of entering a game, the display state of entering a video, the display state of entering an audio, etc.

[0234] S132, determining whether the current display state is a preset display state.

[0235] Among them, the preset display state is determined based on the received historical control information, the historical control information is sent by the control device, the preset display state is the display state entered by the display device after receiving the historical control information, and after entering the preset display state, no control information sent by the control device is received within a preset time.

[0236] Among them, the display state training samples determined by the user through the control device in the text input scenario, video selection scenario and game entertainment scenario of the display device can be used as label data to train the target model by whether the control information is received within a certain time (5s) of entering the display state. During use, the trained target model can be input in the current display state, and the output result is that the control information is not received, then it can be determined that the current display state is the preset display state. Among them, the training samples can be uploaded to the server by multiple display devices, and the server sends the trained target model to the display device for use. In this way, as the amount of training sample data increases, the accuracy of the target model predicting that the current display state is the preset display state is improved, and the target model prediction increases the number of predicted scenarios.

[0237] In addition, by obtaining the historical control information corresponding to the current display device, the preset display state can be determined in advance and then stored. During use, the current display state can be compared to see if it is the preset display state, thereby realizing personalized storage of the preset display state for the display device and improving the hit rate of the specific user's habits of using the control device.

[0238] S133: If the current display state is a preset display state, determining that the current display state indicates that no information sent by the control device will be received within a preset time.
