Description

Technical Field

[0001] The present application relates to the technical field of set-top boxes, and provides a dust removal method, device, equipment and medium for an IPTV set-top box. Background Art

[0002] During the use of an IPTV set-top box, dust usually accumulates inside the set-top box. The dust may contain some fine particles, metal debris, etc. After these substances enter the inside of the set-top box, they may be adsorbed on the surface of the heat sink or electronic components under the action of static electricity. Therefore, it is necessary to regularly clean the inside of the set-top box.

[0003] Currently, the cleaning method adopted is to use a dry soft cloth or paper towel to wipe the outer shell, heat dissipation holes and other parts of the set-top box to remove the surface dust. For a set-top box with a detachable outer shell, the outer shell of the set-top box can be opened to wipe the visible parts inside. During the wiping process, if the electronic components or circuits inside the set-top box are accidentally touched, problems such as component damage and circuit loosening may occur, affecting the normal use of the set-top box. If the wiping tool used is too wet or has static electricity, it may also damage the set-top box. If a small vacuuming tool is used to blow air at the heat dissipation holes, gaps and other parts of the set-top box, the blowing will cause the dust to fly up and may fall back into the set-top box or other electronic devices. Therefore, the dust removal effect of the existing manual dust removal method is not good. Summary of the Invention

[0042] To make the objectives, technical solutions, and advantages of this application clearer and more understandable, the following will clearly and completely describe the technical solutions in the embodiments of this application with reference to the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in this application without making creative efforts belong to the scope of protection of this application. Without conflict, the embodiments in this application and the features in the embodiments can be combined arbitrarily with each other. And although the logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in a different order than here.

[0043] To solve the problem that the existing manual dust removal method has poor dust removal effect on the inside of the set-top box, the embodiments of this application provide a dust removal method for an IPTV set-top box, which is applied to the controller of the set-top box. The following introduces the application scenarios of this application. The following makes some simple introductions to the application scenarios applicable to the technical solutions of the embodiments of this application. It should be noted that the application scenarios introduced below are only used to illustrate the embodiments of this application rather than to limit them. In the specific implementation process, the technical solutions provided by the embodiments of this application can be flexibly applied according to actual needs.

[0044] Please refer to Figure 1 , which is a schematic diagram of an application scenario provided by the embodiments of this application. This application scenario includes a set-top box and a television, and the set-top box and the television are communicatively connected. The set-top box can receive signals from a television signal source (such as cable TV, satellite TV, streaming media services, etc.) and convert them into a format that the television can display. The set-top box is connected to the television through interfaces such as HDMI and AV, and transmits video signals and audio signals to the television, and then the television performs display and playback.

[0045] Please refer to Figure 2 , which is a schematic connection diagram of the internal structure of the set-top box provided by the embodiments of this application. The inside of this set-top box is provided with a controller, a first dust sensor, a dust suction device, an electric push rod, and a dust collection box. The dust suction device is electrically connected to the dust collection box, the push rod is mechanically connected to the dust collection box, and a second dust sensor is arranged inside the dust collection box.

[0046] The controller, also known as the control chip, is used to coordinate the work of each module (the first dust sensor, the second dust sensor, the dust suction device, the push rod). The first dust sensor and the second dust sensor are dust sensors located at different positions, and their main function is to detect the dust information in the space where they are located. Common dust sensors include photoelectric sensors and capacitive sensors.

[0047] The dust suction device is used to absorb the dust inside the set-top box. The push rod is used to drive the dust collection box to move. The dust collection box is a container for holding dust, and the dust collection box can be a cuboid or a cube. Elastic metal contacts are designed at the interface between the dust collection box and the dust suction device. When the dust collection box is inserted into the set-top box, the metal contacts can be in close contact to achieve electrical connection.

[0048] Please refer to Figure 3 , which is a schematic diagram of the position of the internal structure of the set-top box provided by the embodiment of the present application. The dust collection box, like the USB interface and the HDMI interface, is located on the right side inside the set-top box. The dust suction device includes a fan and an air duct, and the rotation speed of the fan can be adjusted according to the target dust suction mode. The suction port of the air duct faces the components with more dust accumulation inside the set-top box, such as the heat sink. A detachable filter screen is provided at the suction port to initially filter larger dust particles and prevent them from entering the inside of the dust suction device. A rear-mounted fan is adopted. Since the dust is initially filtered by the filter screen before reaching the fan, the fan is less eroded and worn by the dust, which helps to extend the service life of the fan and reduce the decline in fan performance (such as reduced rotation speed and reduced air volume) caused by dust accumulation.

[0049] A button is provided at the middle position on the side of the dust collection box away from the inside of the set-top box. The surface of the button has texture to facilitate user pressing. By pressing the button on the dust collection box, the user can achieve the automatic sliding in and out of the dust collection box. For example, a spring is installed at the end of the track of the dust collection box. One end of the spring is fixed to the fixed structure inside the set-top box, and the other end is connected to the dust collection box. When the user presses the button, the button is in a depressed state, and the spring is compressed to store energy. When the user releases the button, the button is in a flat state, and the spring releases energy to help the dust collection box pop out, disconnecting the connection point between the dust collection box and the dust suction device. The elastic coefficient of the spring should be appropriate, which can not only provide sufficient popping force but also prevent the dust collection box from popping out too violently, causing dust to fly or damaging the device.

[0050] There is a reserved space on the right side inside the set-top box that matches the size of the dust collection box. The dust collection box can be inserted into the reserved space inside the set-top box. Tracks are provided in the reserved space. The tracks are made of plastic and have a smooth surface to reduce friction. Card slots that match the tracks are provided on both sides of the dust collection box. The size of the card slots should be precise, and the tolerance is controlled within a very small range to ensure the stability and smoothness when the dust collection box is inserted. The length of the track is slightly longer than the length of the inserted part of the dust collection box, so that there is a certain positioning space after the dust collection box is completely inserted. When the user removes the dust collection box and cleans the dust inside the dust collection box, the dust collection box can be placed at the notch on the right side of the set-top box, and the dust collection box can be slowly pushed in to connect the interface between the dust collection box and the vacuum cleaner device.

[0051] Combined with Figure 4, The embodiment of the present application further provides a dust removal method for an IPTV set-top box that can be applied to the above set-top box. Among them, the method steps defined by the process related to the dust removal method of the IPTV set-top box can be implemented by the controller of the set-top box.

[0052] The following will Figure 4 elaborate in detail on the specific process shown.

[0053] S401. Control the first dust sensor to detect the dust amount and particulate size information inside the set-top box.

[0054] In a specific implementation process, the controller can control the first dust sensor to detect the dust information inside the set-top box at regular intervals (for example, every 1 minute). The dust information includes the dust amount and particulate size information. After the first dust sensor detects the dust amount and particulate size information inside the set-top box, it sends them to the controller.

[0055] Considering the complex internal structure of the set-top box, a single dust sensor cannot comprehensively detect the dust information inside the set-top box. In a possible embodiment, the first dust sensor is a plurality of dust sensors, and the plurality of dust sensors are evenly distributed inside the set-top box. After each dust sensor detects the dust amount and particulate size information at the corresponding position, it sends the detection time to the controller together.

[0056] S402. Determine the target dust suction mode from multiple dust suction modes according to the particulate size information inside the set-top box.

[0057] In a specific implementation process, when the first dust sensor is a single dust sensor, the controller directly determines the target dust suction mode from multiple dust suction modes according to the particulate size information detected by the dust sensor. When the first dust sensor includes a plurality of dust sensors, after the controller receives the particulate size information detected by the plurality of dust sensors at each moment, it determines the target dust suction mode from multiple dust suction modes according to the particulate size information detected by the plurality of dust sensors at the same moment.

[0058] The dust suction device has multiple dust suction modes, including a strong dust suction mode, a standard dust suction mode, and a silent dust suction mode. The parameters such as suction force, noise, and energy consumption of each dust suction mode are different. In terms of suction force, noise, and energy consumption, the strong dust suction mode > the standard dust suction mode > the silent dust suction mode.

[0059] In a possible embodiment, according to the particulate size information inside the set-top box, if it is determined that there are particulates larger than the first size inside the set-top box, the strong vacuuming mode is determined as the target vacuuming mode; if it is determined that there are no particulates of the first size inside the set-top box and there are particulates larger than the second size, the standard vacuuming mode is determined as the target vacuuming mode; the first size is larger than the second size; if it is determined that there are no particulates larger than the second size inside the set-top box, the silent vacuuming mode is determined as the target vacuuming mode.

[0060] In the embodiment of the present application, the first size is, for example, 10 microns, and the second size is, for example, 2.5 microns. When there are relatively large particulates inside the set-top box, considering that relatively large particulates are usually more deposited and not easily cleaned up by slight suction, the strong vacuuming mode can efficiently remove relatively large particulates, ensuring that large particulates are not overlooked and avoiding dust accumulation from affecting the normal operation of the set-top box. When there are no relatively large particulates inside the set-top box but there are particulates of general size, the standard vacuuming mode can effectively clean these particulates of general size while avoiding the possible noise and energy waste caused by the strong vacuuming mode. If there are only relatively small particulates inside the set-top box, the silent mode can reduce noise without affecting the cleaning effect, improving the user experience.

[0061] S403. When the dust amount inside the set-top box is greater than the first threshold, start the dust suction device.

[0062] In the specific implementation process, when the first dust sensor is a single dust sensor, the controller directly determines the dust amount inside the set-top box according to the dust amount detected by this dust sensor. When the first dust sensor includes multiple dust sensors, after the controller receives the dust amounts detected by the multiple dust sensors at each moment, the sum of the dust amounts detected by the multiple dust sensors at the same moment is used as the dust amount inside the set-top box.

[0063] The controller can determine whether the dust amount inside the set-top box is greater than the first threshold. The first threshold can be a preset value. If the dust amount inside the set-top box is less than or equal to the first threshold, it means that the dust inside the set-top box is less and does not need to be cleaned. If the dust amount inside the set-top box is greater than the first threshold, it means that the dust inside the set-top box is more and needs to be cleaned immediately. The dust suction device can be started immediately to make the dust suction device start working.

[0064] S404. Control the dust suction device to adopt the target vacuuming mode to suck the dust inside the set-top box into the dust collection box.

[0065] In a possible embodiment, when the dust amount inside the set-top box is greater than the first threshold, determine the power-on / off state of the set-top box; if the set-top box is in the power-on state and the target vacuuming mode is the silent vacuuming mode, or, the set-top box is in the power-off state, start the dust suction device.

[0066] In the embodiment of the present application, if the set-top box is in the powered-on state, but since the target vacuuming mode is the silent vacuuming mode which can avoid noise interference, starting the vacuuming device in the silent vacuuming mode can clean the set-top box without disturbing the user's use and ensure that the heat dissipation function of the set-top box is not blocked by dust. If the set-top box is in the powered-off state, since the user is not using the set-top box, starting the vacuuming device at this time, no matter which vacuuming mode is adopted, it will not interfere with the user.

[0067] In a possible embodiment, after determining the power-on and power-off state of the set-top box when the dust amount inside the set-top box is greater than the first threshold, the method further includes:

[0068] If the set-top box is in the powered-on state and the target vacuuming mode is the strong vacuuming mode or the standard vacuuming mode, determine the idle time period of the set-top box according to the historical running time of the set-top box; when the idle time period arrives, start the vacuuming device.

[0069] In the embodiment of the present application, if the set-top box is in the powered-on state and the target vacuuming mode is a noisy vacuuming mode, in order not to disturb the normal use of the user, the idle time period of the set-top box can be inferred according to the historical running time of the set-top box, for example, 00:00 - 5:00. Starting the vacuuming device during the time when the user does not use the set-top box can avoid generating noise and interfering with the normal use of the user when the user is watching a program or using the set-top box. And vacuuming when the set-top box is powered off can give full play to the role of the vacuuming device, because when the device is powered off, the internal components are not affected by the operating state and the vacuuming effect may be more ideal.

[0070] After the dust inside the set-top box is absorbed into the dust collection box by the vacuuming device, there are two ways to stop starting the vacuuming device, which are introduced separately below.

[0071] The first way is to determine the working duration corresponding to the target vacuuming mode, and after the working duration, stop starting the vacuuming device.

[0072] In the embodiment of the present application, the working duration corresponding to each vacuuming mode is pre-stored in the controller, and the working duration corresponding to each vacuuming mode can be the same or different. The controller starts the vacuuming device to run in the target vacuuming mode, sets a timer, and automatically stops starting the vacuuming device after the working duration ends.

[0073] The second way is to stop starting the vacuuming device when the dust amount inside the set-top box is less than the first threshold.

[0074] In the specific implementation process, the controller can control the first dust sensor to detect the dust amount inside the set-top box every certain period (for example, 2 seconds), and feedback it to the controller. When the dust amount inside the set-top box is less than the first threshold, it indicates that the dust amount inside the set-top box is small, and the dust collection device is automatically stopped from starting.

[0075] In the embodiment of the present application, the controller can control the start and stop of the dust collection device according to the dust amount, start the dust collection device when the dust amount is large, and stop the dust collection device when the dust amount is small, avoiding resource waste caused by running the dust collection device when the dust is less.

[0076] In a possible embodiment, after stopping the start of the dust collection device, the method further includes:

[0077] Controlling the second dust sensor to detect the dust amount in the dust collection box; when the proportion of the dust amount in the dust collection box is greater than the second threshold, controlling the electric push rod to move to push the dust collection box out of the set-top box.

[0078] In the specific implementation process, after stopping the start of the dust collection device, the controller can control the second dust sensor to detect the dust amount in the dust collection box, compare the proportion of the dust amount in the dust collection box with the second threshold (for example, 80%). If the proportion of the dust amount in the dust collection box is greater than the second threshold, it indicates that the dust collection box is almost full and needs to be cleaned in time. At this time, the controller can control the electric push rod to move. Since the electric push rod is mechanically connected to the dust collection box, the electric push rod will drive the dust collection box to move together and push the dust collection box out of the set-top box.

[0079] In the embodiment of the present application, by using the second dust sensor inside the dust collection box to monitor the proportion of the dust amount in the dust collection box in real time, it can accurately judge whether the dust collection box needs to be cleaned. This automatic judgment avoids manual intervention, so that the user does not have to check the dust amount in the dust collection box personally, reducing the maintenance frequency and the complexity of the operation. Once the dust amount in the dust collection box reaches the set threshold, the dust collection box is automatically pushed out to avoid dust overflow in the dust collection box, facilitating the user to clean the dust collection box in time and ensuring the long-term high efficiency of the set-top box.

[0080] In a possible embodiment, after controlling the electric push rod to push the dust collection box out of the set-top box when the proportion of the dust amount in the dust collection box is greater than the second threshold; the method further includes:

[0081] If it is determined that the TV is in the on state, display dust removal information on the current interface of the TV to remind the user to clean the dust collection box.

[0082] In the specific implementation process, when the user is watching TV, display dust removal information on the TV screen, such as "The dust collection box is full, please clean it in time". After the user cleans the dust in the dust collection box, the empty dust collection box can be inserted into the set-top box again.

[0083] In the embodiments of the present application, when users watch TV, they can see the cleaning prompt, without the need to frequently check the dust amount in the dust collection box, saving their time and energy. At the same time, the timeliness of cleaning the dust collection box is improved, and the risk of equipment failure or reduced suction effect caused by untimely cleaning is reduced.

[0084] In a possible embodiment, the controller can respond to the user's setting operation, immediately start the dust suction device, and control the dust suction device to adopt the target dust suction mode to suck the dust inside the set-top box into the dust collection box.

[0085] In the embodiments of the present application, users can find the setting interface of the dust suction function in the menu interface of the IPTV function, and operate the dust suction device through the remote control. For example, they can start the dust suction device at any time, set the target dust suction mode, and stop the target dust suction mode at any time. Users can operate the dust suction device according to actual needs to enhance the user experience.

[0086] In a possible embodiment, the controller can start the dust suction device at preset intervals, control the dust suction device to adopt the silent dust suction mode, suck the dust inside the set-top box into the dust collection box, and stop starting the dust suction device after the working duration corresponding to the silent dust suction mode.

[0087] In the embodiments of the present application, by starting the dust suction device regularly and adopting the silent dust suction mode, it is ensured that the dust suction process is quiet and efficient, while avoiding interfering with the daily use of users. The silent mode helps to reduce noise and enhance the user experience, especially suitable for use in a home environment. The timing function can automatically control the dust suction cycle according to user needs, avoiding overwork or missed cleaning, and ultimately achieving a balance between cleaning and energy conservation.

[0088] In a possible embodiment, the set-top box further includes a system control module for device management and power management, responsible for the basic information management of the set-top box itself and the intelligent dust suction integrated device, including reading and displaying information such as the model, serial number, and hardware version of the device, so that users can understand the basic situation of the device. At the same time, this module can also monitor the connection status and operation status of the device to ensure normal communication and operation between the set-top box and the dust suction device. When problems such as motor failure, sensor abnormality, and blockage occur, an alarm signal is sent in a timely manner, and the fault information is fed back to the TV set to feedback the status, progress, and result of the dust suction operation to the user.

[0089] In a possible embodiment, the system control module can also be used for power management to manage and control the power supply of the set-top box, including switching the power states such as power-on, power-off, and standby of the set-top box. For the dust suction device, the power can be reasonably allocated according to the working requirements. For example, sufficient power supply is ensured when the dust suction device is working, and the low-power mode is entered when the dust suction device is idle to save energy.

[0090] In summary, the embodiments of the present application provide a dust removal method for an IPTV set-top box, which can prevent dust accumulation from affecting the heat dissipation efficiency, keep the heat dissipation channel unobstructed, ensure good heat dissipation effect of the set-top box, maintain a stable working temperature, enable the set-top box to always work within a suitable temperature range, and ensure the stable performance of its performance. Reduce the erosion of dust on electronic components and improve the reliability of the set-top box. By using an intelligent dust suction device to keep the inside of the set-top box clean, it is possible to reduce the damage of dust to the hardware and delay the aging speed of the hardware, thereby extending the service life of the set-top box.

[0091] Based on the same inventive concept, as Figure 5 shown, the embodiments of the present application also provide a dust removal device for an IPTV set-top box, which is arranged in the controller of the set-top box; a first dust sensor, a dust suction device, and a dust collection box are arranged inside the set-top box; the dust suction device is electrically connected to the dust collection box; the device includes:

[0092] A control module for controlling the first dust sensor to detect the dust amount and particle size information inside the set-top box;

[0093] A determination module for determining a target dust suction mode from multiple dust suction modes according to the particle size information inside the set-top box;

[0094] A start module for starting the dust suction device when the dust amount inside the set-top box is greater than a first threshold;
