Description

[Technical Field]

[0001] [CROSS-REFERENCE TO RELATED APPLICATIONS] This application claims priority to Chinese Patent Application No. CN202110645969.4, filed on June 9, 2021, entitled "Method, device, device and storage medium for identifying the risk of water ingress into the entire device," the entire disclosure of which is incorporated herein by reference.

[0002] [Technical field] The present disclosure relates to the field of terminals, and more particularly to a method, an apparatus, a device, and a storage medium for identifying the risk of water ingress in the entire device. [Background technology]

[0003] 2. Description of the Related Art Smart terminals, such as mobile phones and watches, have increasingly high requirements for waterproofing.

[0004] When charging via USB, mobile phones simultaneously check for a short circuit between two different metal pins. If a short circuit occurs, it indicates that water has entered the USB, and the USB circuit is physically disconnected to prevent the USB from burning out due to the short circuit. However, watches are generally not charged via USB, and even if they are charged via a USB port, the USB port is protected by a case, which naturally increases the difficulty of the design.

[0005] Waterproofing of watches is mainly achieved by sealing the entire case, and methods such as adding waterproof silicone rubber rings to the gaps of the entire device can be used to improve the waterproof level, preventing water from entering the case and preventing the entire device from failing due to a short circuit on the motherboard. Such methods increase the difficulty of designing and assembling the entire device, further increasing the cost of the entire device and reducing the aesthetic appeal of the appearance.

[0006] In addition, smart devices such as mobile phones have a large overall volume, and when the entire device is subjected to external force, the entire device undergoes a large amount of bending deformation. This can cause the adhesive filling the gaps throughout the device to fall out, reducing the sealing performance of the case and making it easier for water to enter the device, causing short circuits in components on the motherboard and ultimately increasing the risk of water entering the inside of a watch. Summary of the Invention [Problem to be solved by the invention]

[0007] The main objective of the present disclosure is to provide a method, device, equipment, and storage medium for identifying the risk of water ingress into an entire device, in order to identify the risk of water ingress into the entire device of a smart terminal and reduce the risk of water ingress into the interior of the smart terminal without increasing the difficulty of designing and assembling the entire device of the smart terminal.

DETAILED DESCRIPTION OF THE INVENTION

[0013] It will be understood that the specific embodiments described herein are illustrative of the present disclosure only and are not intended to be limiting of the present disclosure.

[0014] In the following description, the use of suffixes such as "module," "member," or "unit" to represent elements is for the purpose of facilitating the description of the present disclosure and does not have any special meaning in itself. Therefore, the terms "module," "member," or "unit" may be used interchangeably.

[0015] FIG. 1 is a flowchart of a method for identifying water ingress risk in an entire device according to an embodiment of the present disclosure. As shown in FIG. 1, the method includes the following steps S101 and S102.

[0016] In step S101, the change amount of the first capacitance signal of the capacitive touch panel due to the connection between the earth wire provided on the surface of the smart terminal case and the capacitive touch panel chip earth of the smart terminal, and the change amount of the second capacitance signal of the capacitive touch panel due to the disconnection are respectively obtained.

[0017] The ground wire and the capacitive touch panel chip ground are connected / disconnected within a predetermined time interval. For example, the ground wire and the capacitive touch panel chip ground are connected, and a change in a first capacitance signal of the capacitive touch panel caused by connecting the ground wire and the capacitive touch panel chip ground is obtained. Then, within a predetermined time interval after connecting the ground wire and the capacitive touch panel chip ground, the ground wire and the capacitive touch panel chip ground are disconnected, and a change in a second capacitance signal of the capacitive touch panel caused by disconnecting the ground wire and the capacitive touch panel chip ground is obtained. That is, the ground wire and the capacitive touch panel chip ground are connected / disconnected once within a predetermined time interval, for example, 0.02 seconds, and a change in the first capacitance signal and a change in the second capacitance signal are obtained.

[0018] In step S102, a water ingress risk of the entire smart terminal device is identified based on the acquired change amount of the first capacitance signal and the acquired change amount of the second capacitance signal.

[0019] For example, if the change amount of the first capacitance signal is determined to be in the first threshold interval or the second threshold interval, and the change amount of the second capacitance signal is determined to be in the first threshold interval or the second threshold interval, and if the change amount of the first capacitance signal is determined to be in the first threshold interval and the change amount of the second capacitance signal is determined to be in the second threshold interval, it is determined that there is water on the surface of the capacitive touch panel and the smart device is identified as having a risk of water ingress; if the change amount of the first capacitance signal and the change amount of the second capacitance signal are both determined to be in the first threshold interval, it is determined that there is no water on the surface of the capacitive touch panel, for example, a hand is above the capacitive touch panel and the smart device is identified as having no risk of water ingress. The change amounts of the capacitance signals in the first threshold interval are all greater than the change amounts of the capacitance signals in the second threshold interval.

[0020] Furthermore, if there is a risk of water ingress into the entire smart device, the method further includes a step of issuing a warning by vibration, ringing, voice broadcast, screen display, etc., or sending a warning to another device capable of communicating with the smart device to prompt the user to wipe off water on the surface of the case and / or move away from the water source, and recording the time and duration of the occurrence of the risk of water ingress into the entire smart device, or sending the time and duration of the occurrence to another device capable of communicating with the smart device and recording it.

[0021] The earth wire is provided on the surface of the smart device case near the cover glass, for example, along the edge of the cover glass, and the closed or open earth wire can be provided at a location on the edge of the cover glass where water is likely to get in.

[0022] The capacitive touch panel chip ground may be a ground pin of the capacitive touch panel chip, or a ground wire drawn from the ground pin of the capacitive touch panel chip, and may be connected to a ground wire on the surface of the case via a switch device.

[0023] The present invention uses existing devices in smart terminals to identify and determine whether there is water on the surface of the display through software functions, and if there is water, it can prompt the user to use a different method to quickly remove the smart terminal from the water-exposed environment and reduce the risk of water getting inside the smart terminal.

[0024] The smart terminal may be a watch (including a children's watch and an adult wearable watch), a mobile phone (including a children's mobile phone), a bracelet, etc.

[0025] Smart terminals such as children's watches and mobile phones generally include a capacitive touch panel sensor, a capacitive touch panel chip, and a display for touch and display, and also include a smart operating system for human-computer interaction. The following will be described in detail using a children's watch as an example.

[0026] A children's watch is a portable smart device that integrates various functions such as calling, positioning, electronic fences, and emergency rescue. With the development of smart functions, it is gradually equipped with more functions such as video calling, music playback, video viewing, and games. As shown in Figure 2, currently, a children's watch 100 typically includes a cover crystal 1, a capacitive touch panel sensor 2, a capacitive touch panel chip 3, and a display 4, which are used for touch and display. The children's watch 100 uses a smart operating system to perform human-computer interaction operations.

[0027] After children start wearing a children's watch, they are unable to properly protect it. As electronic products, waterproofing is crucial for children's watches. Water entering the watch can cause short circuits in the motherboard, damaging the components and ultimately damaging the watch. While children's watches are typically waterproof, the waterproofing gradually deteriorates over time, making it difficult to prevent water from entering the watch. If children fail to recognize the danger posed by water in their environment while using the watch, the watch may be exposed to water for extended periods of time, dramatically increasing the risk of water entering the watch.

[0028] The waterproof design solution for children's watches improves the waterproof ability of the children's watch itself, preventing water from entering the entire device, while also improving children's awareness of waterproofing, reducing the risk of the watch being placed in an environment where there is water around it, and ensuring that the watch is always in a dry environment, thus greatly reducing the risk of water getting into the watch.

[0029] A capacitive touch panel is located beneath a glass cover and uses an ITO (indium tin metal oxide) layer as a conductive layer, with electrodes extending horizontally and vertically. When a user touches the capacitive touch panel, the user's finger and the ITO electrode form a coupled capacitance. The finger's touch alters the distribution of the original capacitance field, allowing the system to detect changes in the signal levels of the horizontal and vertical electrodes to identify whether a finger is touching the glass cover. The signal level of the capacitance signal changes whether the finger touches the glass cover or if there are water droplets on it. However, there is a difference between the signal levels of the capacitance signals corresponding to the finger and the water droplets. This difference allows a preliminary determination of whether a finger is touching or there are water droplets on the glass cover. However, when the finger is far from the glass cover, i.e., at a certain distance, the change in the capacitance signal corresponding to the finger and the change in the capacitance signal corresponding to the water droplet are relatively close, making it impossible to determine whether there is a water droplet or a finger. Therefore, the present disclosure grounds the water droplet, rapidly increasing the amount of change in the capacitance signal caused by the water droplet until it approaches or becomes the same as the amount of change when a finger touches the cover glass, making it possible to distinguish whether a finger is touching or there is a water droplet on the cover glass.

[0030] As shown in FIG. 2, a capacitive touch panel sensor 2 for human-computer interaction in a smart device such as a children's watch or a mobile phone is located above a display 4 and collects capacitance signals. When a finger touches a cover glass 1 above the capacitive touch panel sensor 2, the horizontal and vertical sensors in the capacitive touch panel sensor 2 collect the capacitance signal changes and calculate the coordinates of the finger's touch. In a smart device, the capacitive touch panel sensor 2 enables interaction input between the user and the watch 100, and the display 4 displays the result of the interaction. After water is applied to the surface of the cover glass 1, the horizontal and vertical sensors in the capacitive touch panel sensor 2 collect the capacitance signal changes, but the change in the capacitance signal is smaller than the capacitance signal when a finger touches the cover glass 1. Typically, the change in the capacitance signal at this time is insufficient to reach the preset threshold for the capacitive touch panel to trigger an alarm, so no alarm is issued. Metal wiring (also called earth wire or metal earth wire) 5 as shown in Figures 3 to 5 is attached and arranged around the periphery of cover glass 1 of a smart terminal, and metal wiring 5 is connected to the chip earth (or chip ground pin) of capacitive touch panel chip 3 or to an earth wire drawn from the chip earth, and a switch device that can connect and disconnect the earth wire is attached and arranged on capacitive touch panel chip 3, for example, by earth wire connect / disconnect switch 6 shown in Figure 5, the earth wire can be connected and disconnected at the appropriate time.

[0031] Normally, when water flows over the surface of the cover glass 1, the capacitive touch panel collects a change in the capacitance signal, but this signal is not enough to determine that it is water. For example, when a finger is far from the cover glass 1, i.e., at a certain distance, the change in the capacitance signal caused by the finger and the change in the capacitance signal caused by a water droplet are relatively similar, making it impossible to determine whether it is a water droplet or a finger. Therefore, by grounding the water droplet, the change in the capacitance signal caused by the water droplet increases rapidly until it is close to or equal to the change caused by a finger touching the cover glass 1, making it possible to distinguish whether it is a finger touching or a water droplet on the cover glass 1. A ground wire 5 is connected to the case and this ground wire 5 is connected to the capacitive touch panel chip 3. After water is grounded, the capacitance signal collected by the capacitive touch panel becomes clearer and stronger. When water covers the surface of the capacitive touch panel, the change in the capacitance signal when water is grounded and when it is not grounded are within different capacitance ranges. Therefore, it can be determined that there is water on the surface of the display based on the change in the signal amount. In short, this application realizes the identification of the risk of water ingress for the entire device by drawing the ground wire from the capacitive touch panel chip to the surface of the case of the capacitive touch panel and connecting / disconnecting the ground wire drawn from the capacitive touch panel chip to the surface of the case of the capacitive touch panel.

[0032] To prevent water from entering the entire device, the user needs to wipe off any water from the surface of the device in a timely manner. As shown in Figure 6, after the capacitive touch panel chip 3 determines that there is water on the surface of the cover glass 1, it sends a signal to the central processing unit 7, which then vibrates the motor 8, plays a sound from the horn 9, or displays a notification message on the display 4, thereby prompting the user to wipe off any water from the entire device in a timely manner.

[0033] Furthermore, if the presence of water is identified based on the signal amount, the occurrence time and duration of the water detection are recorded, and the longer the duration, the greater the risk of water getting in. At the same time, the device can also upload this data to a cloud server, and the cloud server stores the occurrence time and duration of water being present around the device.

[0034] Furthermore, if water is detected, and the device is unable to recognize the fingerprint when performing an operation such as fingerprint recognition, a message can be displayed urging the user to wipe off the water from the display surface before performing the fingerprint recognition operation. At the same time, the device can also prompt the user to wipe off the water from the touch panel surface to improve the touch effect of the finger.

[0035] FIG. 7 is a flowchart showing how a wristwatch according to an embodiment of the present disclosure identifies the risk of water ingress into the entire device, and as shown in FIG. 7, the following steps S201 to S204 may be included.

[0036] In step S201, a switch device 6 is disposed on or near the capacitive touch panel chip 3, and one end of the switch device 6 is connected to a metal ground wire 5 and the other end is connected to the chip ground of the capacitive touch panel chip 3. When the switch device 6 is turned on, the metal ground wire 5 is connected to the chip ground, and when the switch device 6 is turned off, the metal ground wire 5 is disconnected from the chip ground. The capacitive touch panel chip 3 connects and disconnects the metal ground wire 5 and the chip ground once within a certain time interval.

[0037] In step S202, if water is present on the surface of the cover glass 1 while the metal ground wire 5 is connected, the water touches the metal ground wire 5. Because the metal ground wire 5 is connected to the chip earth, the change in the capacitance signal collected by the capacitive touch panel sensor 2 is large, corresponding to the change in capacitance when touched by a finger. The threshold interval at this time is designated as the first threshold interval, and the change in the capacitance signal is within the first threshold interval. If water is present on the surface of the cover glass 1 while the metal ground wire 5 is disconnected from the chip earth, the water touches the metal ground wire 5. Because the metal ground wire 5 is not connected to the chip earth, the change in the capacitance signal collected by the capacitive touch panel sensor 2 is small, smaller than the change in capacitance when touched by a finger. The threshold interval at this time is designated as the second threshold interval, and the change in the capacitance signal is within the second threshold interval.

[0038] In step S203, the capacitive touch panel chip 3 determines whether water is present on the cover glass 1 based on the change in capacitance signal collected by the capacitive touch panel sensor 2 when the metal ground wire 5 and the chip earth are connected and disconnected. For example, if the change in capacitance signal obtained when the metal ground wire 5 and the chip earth are connected and disconnected is both within a first threshold interval, it indicates that a finger is touching the capacitive touch panel. If the change in capacitance signal obtained when the metal ground wire 5 and the chip earth are connected and disconnected is within a different interval, it indicates that water is present on the surface of the cover glass 1. If it is determined that water is present on the surface of the cover glass 1, it sends a signal indicating the presence of water to the central processing unit 7.

[0039] In step S204, after receiving the signal indicating that there is water on the cover glass 1 sent from the capacitive touch panel chip 3, the central processing unit 7 prompts the user via the display 4, motor 8, horn 9, etc., for example, by displaying a message on the display 4 urging the user to wipe the water as quickly as possible, vibrating the motor 8, or playing a sound from the horn 9, thereby prompting the user to wipe the water as quickly as possible. At the same time, the central processing unit 7 records the occurrence time and duration.

[0040] In an embodiment of the present invention, a ground wire is extended from the capacitive touch panel chip, and the connection and disconnection of the ground wire are controlled so that the ground wire can be in a grounded state or a floating, ungrounded state. The extended ground wire is attached to the surface of the smart device case. When water droplets cover the surface of the touch panel cover and the ground wire on the surface of the case, the touch panel detects that the capacitance signal changes differently between the grounded state and the floating, ungrounded state, indicating the presence of water on the surface of the touch panel. The touch panel identifies the change in capacitance signal to identify that water has covered the surface of the cover glass, and finally determines the risk of water to the smart device such as a wristwatch, and prompts the user to keep the smart device away from water by means of displaying information, vibrating, or sounding, recording the time and duration of the water ingress, and prompting the user to wipe the water off the surface of the display, thereby improving the effectiveness of the touch panel's surface operation or fingerprint recognition, etc.

[0041] FIG. 8 is a block diagram of an apparatus for identifying water ingress risk in an entire device according to an embodiment of the present disclosure. As shown in FIG. 8, the apparatus may include a signal acquisition module 10 and a risk identification module 20.

[0042] The signal acquisition module 10 is configured to acquire the change in the capacitance signal of the capacitive touch panel of the smart device when the ground wire on the surface of the smart device case and the capacitive touch panel chip ground of the smart device are connected / disconnected.

[0043] The risk identification module 20 is configured to identify a water ingress risk of the entire equipment of the smart terminal based on the amount of change in the acquired capacitance signal.

[0044] The change amount of the capacitance signal includes a change amount of a first capacitance signal and a change amount of a second capacitance signal.

[0045] For example, the signal acquisition module 10 controls the ground wire and the capacitive touch panel chip earth to connect, and acquires a change in a first capacitance signal of the capacitive touch panel when the ground wire and the capacitive touch panel chip earth are connected, and controls the ground wire and the capacitive touch panel chip earth to disconnect, and acquires a change in a second capacitance signal of the capacitive touch panel when the ground wire and the capacitive touch panel chip earth are disconnected. The risk identification module 20 determines that the change amount of the first capacitance signal is within the first threshold interval or the second threshold interval, and determines that the change amount of the second capacitance signal is within the first threshold interval or the second threshold interval, and determines that the smart device is at risk of water ingress if the change amount of the first capacitance signal is within the first threshold interval and the change amount of the second capacitance signal is within the second threshold interval, and determines that the smart device is not at risk of water ingress if the change amount of the first capacitance signal and the change amount of the second capacitance signal are both within the first threshold interval. The change amounts of the capacitance signals in the first threshold interval are all greater than the change amounts of the capacitance signals in the second threshold interval.

[0046] Furthermore, the device may further include a prompting module configured to prompt a user to at least one of wipe water off the surface of the case and move away from a water source by issuing a warning when there is a risk of water ingress into the smart terminal as a whole, for example, by vibrating, ringing, an audio announcement, a screen display, etc.

[0047] Furthermore, the device may further include a memory module configured to, when the smart terminal has a risk of water ingress into the entire device, record the occurrence time of the risk of water ingress into the entire device of the smart terminal and identify the duration of time the smart terminal is in an environment that comes into contact with water.

[0048] Furthermore, the device may further include a communication module configured to transmit the recorded occurrence time and duration of the water ingress risk of the entire equipment of the smart terminal to a cloud server, and store the occurrence time and duration of the water ingress risk of the entire equipment of the smart terminal by the cloud server.

[0049] The device of this embodiment can be applied to smart devices with capacitive touch panels, such as wristwatches and mobile phones. Typically, when water flows over the display surface of a smart device, the capacitive touch panel collects changes in the capacitance signal. However, this signal is not sufficient to determine whether the water is present. Therefore, a ground wire is connected to the case and connected to the capacitive touch panel chip. After the water is grounded, the capacitance signal collected by the capacitive touch panel becomes clearer and stronger. While water is covering the surface of the capacitive touch panel, the device collects changes in the capacitance signal when the water is grounded and when it is not. The change in the signal amount can be used to determine whether water is present on the display surface. If the two signals are within different capacitance ranges, the device can determine whether water is present on the display surface. To prevent water from entering the entire device, if water is detected on the display surface, the device vibrates the motor, plays a sound, and displays a prompt on the display, prompting the user to wipe off the water from the surface of the device, such as a wristwatch, thereby reducing the risk of water entering the entire device. At the same time, it can encourage users to ensure that devices such as fingerprint readers are in better working condition after wiping off water, thereby improving the lifespan of the product itself, improving the competitiveness of the product, and creating a competitive advantage for terminal products.

[0050] An embodiment of the present disclosure further provides an apparatus for identifying a risk of water ingress into an entire device, the apparatus including a memory and a processor, the memory storing a program executable on the processor, and the steps of the method for identifying a risk of water ingress into an entire device being realized when the program is executed by the processor. The processor may be, for example, a central processing unit, a digital signal processor, or a microprocessor, and the memory may be a storage medium such as RAM, ROM, EEPROM, or flash memory that stores desired information and is accessible by the processor.

[0051] The device of this embodiment can be applied to smart devices with capacitive touch panels, such as wristwatches and mobile phones. Using existing components in devices such as wristwatches, the device determines whether water is present from different angles based on the change in capacitance signal collected by the capacitive touch panel when water is on the ground. If the change in capacitance signal indicates the presence of water, the device records the occurrence and duration of the water detection event. The longer the duration, the greater the risk of water ingress. If water is detected and an operation such as fingerprint recognition is attempted, if the fingerprint cannot be recognized, a display method can prompt the user to wipe the water off the display surface before performing the fingerprint recognition operation.

[0052] This embodiment is applied to a scene where a capacitive touch panel is used to identify whether there is water or not, and uses a device in a smart terminal such as a wristwatch to attract the attention of users such as children, strengthening the awareness of users such as children to protect their smart terminals such as wristwatches from water, and encouraging users such as children to wipe off any water on their wristwatches, thereby protecting terminals such as wristwatches from water.

[0053] An embodiment of the present disclosure further provides a storage medium having one or more programs stored thereon, which, when executed by a processor, implements the steps of the method for identifying water ingress risk for the entire equipment described above. The storage medium may include, but is not limited to, RAM, ROM, EEPROM, flash memory or other memory technology, CD-ROM, digital versatile disk (DVD) or other optical disk storage, tape cartridge, magnetic tape, magnetic disk storage or other magnetic storage device, or any other medium that stores desired information and is accessible by a computer.

[0054] As described above, the method, device, device, and storage medium for identifying the risk of water ingress in an entire device according to the embodiments of the present disclosure acquire a change in a first capacitance signal of the capacitive touch panel when the ground wire on the surface of the smart device case is connected to the capacitive touch panel chip ground of the smart device, and a change in a second capacitance signal of the capacitive touch panel when the ground wire is disconnected from the capacitive touch panel chip ground of the smart device, respectively, and can identify the risk of water ingress in the entire device of the smart device based on the acquired change in the first capacitance signal and the change in the second capacitance signal. As can be seen from this, the risk of water ingress in the entire device of the smart device can be identified without increasing the difficulty of the design and assembly of the smart device, and the smart device can be kept away from environments where it may come into contact with water as soon as possible, thereby reducing the risk of water ingress into the smart device.

[0055] Although the preferred embodiments of the present disclosure have been described in detail above with reference to the accompanying drawings, the technical scope of the present disclosure is not limited to such examples. Any modifications, equivalent substitutions, improvements, etc. made by those skilled in the art without departing from the scope and essence of the present disclosure should be included in the protection scope of the present invention.
