Description

Technical Field

[0001] This invention relates to the field of battery leakage detection technology, and in particular to a battery leakage detection method, control device, and smart wearable device. Background Technology

[0002] Currently, smart wearable devices typically use built-in batteries as their power source. However, because smart wearable devices are used in dynamic environments, they are prone to battery leakage, which can cause corrosion and reduce their lifespan. Summary of the Invention

[0003] The main objective of this invention is to provide a battery leakage detection method, which aims to solve the problem of short lifespan of smart wearable devices due to battery leakage.

[0004] To achieve the above objectives, the present invention proposes a battery leakage detection method applied to a smart wearable device. The smart wearable device has at least one battery compartment, each battery compartment being used to assemble a battery and equipped with a concentration detection circuit. Each concentration detection circuit is used to detect the concentration of volatile organic compounds in its respective battery compartment and output a concentration detection signal. The battery leakage detection method includes:

[0005] Acquire the concentration detection signal output by each concentration detection circuit;

[0006] When it is determined that there is a leaking battery in the smart wearable device based on the detection signals of various organic matter concentrations, the working mode of the smart wearable device is determined according to the number of batteries in the battery compartment, and the smart wearable device is controlled to work in the corresponding working mode.

[0007] Optionally, when it is determined that the number of batteries in the battery compartment is greater than a preset number, the working mode of the smart wearable device is determined to be the first working mode, and the smart wearable device is controlled to work according to the first working mode, and the smart wearable device is controlled to prompt the user that the smart wearable device has a battery leakage fault in a prompting manner that matches the first working mode.

[0008] Optionally, when it is determined that the number of batteries in the smart wearable device is not greater than a preset number, the working mode of the smart wearable device is determined to be the first working mode, and the smart wearable device is controlled to work according to the second working mode, and the smart wearable device is controlled to prompt the user that the smart wearable device has a battery leakage fault in a prompting manner matching the second working mode.

[0009] Optionally, the smart wearable device is controlled to operate according to a first operating mode, and the smart wearable device is controlled to notify the user of a battery leakage fault in a prompting manner matching the first operating mode, including:

[0010] Control the leakage of the battery to stop discharging;

[0011] Control the discharge of the non-leaking battery to power the normal operation of the smart wearable device, and notify the user of the smart wearable device of a battery leakage fault in a prompt manner that matches the first working mode.

[0012] Optionally, the user is notified of a battery leakage fault in the smart wearable device using a prompt method that matches the first operating mode, specifically:

[0013] It indicates the location of each leaking battery in the smart wearable device's battery compartment.

[0014] Optionally, the smart wearable device is controlled to operate according to the second operating mode, and the smart wearable device is controlled to prompt the user with a prompt method matching the second operating mode to indicate that the smart wearable device has a battery leakage fault. Specifically, the steps are as follows:

[0015] Control the display system of smart wearable devices;

[0016] The smart wearable device is controlled to work according to the second working mode, and the smart wearable device is controlled to prompt the user that the smart wearable device has a battery leakage fault in a prompting manner that matches the second working mode.

[0017] After being prompted, control the smart wearable device to shut down.

[0018] Optionally, before the step of acquiring the concentration detection signal output by each concentration detection circuit, the battery leakage detection method further includes:

[0019] The system acquires a leak detection trigger signal and, upon receiving the leak detection trigger signal, controls the smart wearable device to enter the battery leak detection mode and acquires the concentration detection signal output by each concentration detection circuit.

[0020] Optionally, the battery in the smart wearable device is identified as having leakage based on the detection signals of various organic matter concentrations, including:

[0021] The concentration of volatile organic compounds in the battery compartment where the corresponding concentration detection circuit is located is determined based on each temperature detection signal;

[0022] When the concentration of volatile organic compounds in at least one battery compartment reaches a preset concentration threshold, it is determined that there is a leaking battery in the smart wearable device.

[0023] The present invention also proposes a control device, the control device comprising:

[0024] Memory;

[0025] Processor; and

[0026] A battery leakage detection program stored in memory and executable on a processor, wherein the processor, when executing the battery leakage detection program, implements the battery leakage detection method as described above.

[0027] The present invention also proposes a smart wearable device, the smart wearable device comprising:

[0028] At least one battery compartment, each battery compartment being used to assemble a battery, and equipped with a concentration detection circuit, each concentration detection circuit being used to detect the concentration of volatile organic compounds in the battery compartment and output a concentration detection signal; and,

[0029] As described above, the control device is connected to the output terminal of each of the concentration detection circuits.

[0030] This invention acquires the concentration detection signal output by each concentration detection circuit. When a leaking battery is detected in the smart wearable device based on the concentration detection signals of each organic compound, the operating mode of the smart wearable device is determined according to the number of batteries present in the battery compartment, and the smart wearable device is controlled to operate in the corresponding mode. Since the smart wearable device will indicate its current operating status to the user through its display screen or audio-visual prompt circuit when operating in different modes, when any battery in the smart wearable device leaks, the user can be aware of the change in its operating status through the display screen or audio-visual prompt circuit, thus promptly noticing the battery leakage fault. This allows the user to immediately stop using the smart wearable device with a leaking battery and send it for repair. This not only avoids long-term corrosion of the device due to battery leakage without the user's knowledge, thus preventing a short lifespan, but also prevents users from unknowingly using a smart wearable device with a leaking battery and affecting their health. Therefore, it improves both the lifespan and safety of smart wearable devices. Attached Figure Description

[0040] The realization of the objective, functional features and advantages of the present invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0041] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0042] Furthermore, in this invention, descriptions involving "first," "second," etc., are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this invention.

[0043] In one example technology, smart wearable devices use one or more batteries as a power source. However, because smart wearable devices are typically used in dynamic, moving environments rather than static ones, the battery's sealing packaging is prone to failure, leading to battery leakage. Since the battery compartment in a smart wearable device is usually sealed, and users charge the battery via a pre-installed charging port, users are often unaware of leakage and continue using the device normally. This allows the leaked battery fluid to accumulate inside, corroding the device and affecting its lifespan. Furthermore, because smart wearable devices, especially head-mounted ones, are close to the user's respiratory system, corrosion and leaked battery fluid can also negatively impact the user's health.

[0044] To address the aforementioned problems, this invention proposes a battery leakage detection method for use in smart wearable devices. The smart wearable device has at least one battery compartment, each battery compartment is used to assemble one battery, and is equipped with a concentration detection circuit. Each concentration detection circuit is used to detect the concentration of volatile organic compounds in the battery compartment and output a concentration detection signal.

[0045] Reference Figure 1 The battery leakage detection method includes:

[0046] Step S100: Obtain the concentration detection signal output by each concentration detection circuit;

[0047] In this embodiment, the execution entity of the battery leakage detection method of the present invention can be a control device. The control device can be connected to the output terminal of each concentration detection circuit to receive the concentration detection signal output by each concentration detection circuit after detecting the concentration of volatile organic compounds in the battery compartment in real time. It should be noted that when the battery leaks, the leaked liquid will cause the concentration of volatile organic compounds in the assembled battery compartment to increase, thereby causing a corresponding change in the concentration detection signal output by the concentration detection circuit installed in the battery compartment. Therefore, the control device can determine whether the battery assembled in each battery compartment is leaking by acquiring the concentration detection signal output by each concentration detection circuit.

[0048] Step S200: When it is determined that there is a leaking battery in the smart wearable device based on the detection signals of each organic matter concentration, the working mode of the smart wearable device is determined according to the number of batteries in the battery compartment, and the smart wearable device is controlled to work in the corresponding working mode.

[0049] In this embodiment, the control device can determine the number of batteries present in the battery compartment after determining that battery leakage has occurred. For example, each battery compartment may have positive and negative contacts corresponding to the installed batteries. The control device can determine that the installed batteries in a battery compartment are present when the positive and negative contacts in a battery compartment have voltage values, and determine that the installed batteries in a battery compartment are not present when the positive and negative contacts in a battery compartment do not have voltage values. Alternatively, each battery compartment may be equipped with a battery presence detection circuit, which can be implemented using a pressure sensor, an infrared transceiver assembly, an ultrasonic transceiver assembly, etc. The detection terminal of each battery presence detection circuit can be set to correspond to the battery mounting position in the battery compartment to detect whether the battery at the mounting position is present, and output a battery presence signal or a battery absence signal to the control device, so that the control device can determine the number of batteries present based on the received presence signal. Of course, in practical applications, there may be more methods for obtaining the number of batteries present, which will not be elaborated here.

[0050] The control device can call up the corresponding preset working mode or calculate and generate the corresponding real-time working mode based on the number of batteries in place. ， The preset operating modes and real-time operating modes may include, but are not limited to: normal mode, low-power mode, sleep mode, security mode, wearable mode, alarm mode, etc. Specifically, the control device may have multiple preset battery availability quantities and multiple preset operating modes pre-integrated. Each preset battery availability quantity corresponds to a preset operating mode. The control device can directly call the corresponding preset operating mode based on the acquired battery availability quantity; or, the control device may have an integrated operating mode generation algorithm that runs based on the acquired battery availability quantity to generate a real-time operating mode corresponding to the acquired battery availability quantity. The control device can configure the invoked preset operating mode or the generated real-time operating mode as the subsequent operating mode of the smart wearable device, and can control the operating conditions of each functional component in the smart wearable device according to the configured operating mode, so that the smart wearable device as a whole can operate in the configured operating mode.

[0051] Because smart wearable devices use their displays or audio-visual prompts to indicate their current operating status when operating in different modes, users can easily detect battery leakage if any battery in the device leaks. This allows them to immediately stop using the device and have it repaired, preventing unknowingly corroding the device and shortening its lifespan. This addresses the issue of short lifespan due to battery leakage and also protects users' health from the health risks associated with unknowingly using a device with a leaking battery. Therefore, it improves both the lifespan and safety of smart wearable devices.

[0052] Reference Figure 1 When it is determined that the number of batteries in the battery compartment is greater than the preset number, the working mode of the smart wearable device is determined to be the first working mode, and the smart wearable device is controlled to work according to the first working mode, and the smart wearable device is controlled to prompt the user that the smart wearable device has a battery leakage fault in a prompting manner that matches the first working mode.

[0053] In this embodiment, the smart wearable device may also include a power management circuit and a multiplexer circuit. Each battery can be connected to the power management circuit through a switch circuit. The controlled terminal of each switch circuit can be connected to a control device to be turned on or off under the control of the control device. Each switch circuit can connect the battery to the power management circuit when it is turned on and disconnect the connection between the corresponding battery and the power management circuit when it is turned off.

[0054] Optionally, the first operating mode can be a normal operating mode. The control device can compare the acquired number of batteries in place with a preset number. When the comparison result shows that the number of batteries in the battery compartment is greater than the preset number, it indicates that there are more batteries in place. At this time, the control device can control the smart wearable device to operate in normal operating mode. In normal operating mode, the control device can control the switching circuit connected to the leaking battery to close, so that the leaking battery stops discharging, and control the switching circuit connected to the non-leaking battery to open, so that the power management circuit can access the discharge voltage of each non-leaking battery to provide power for the smart wearable device to power on or continue to operate, and prompt the user that there is battery leakage. After the prompt is completed, the control device can control the smart wearable device to continue to power on or operate.

[0055] In another embodiment, the control device can further determine whether all batteries in the battery compartment are leaking when the number of batteries in the compartment exceeds a preset number. If the determination is that all batteries are leaking, the control device can operate the smart wearable device in a safe mode, regardless of whether the smart wearable device is powered on or off. In safe operating mode, the control device can control the activation of various switching circuits to provide power for powering on or continuing to operate the smart wearable device, and can control the display screen or audio-visual prompt circuit to issue corresponding prompts to inform the user that all batteries are leaking. After the prompt is completed, the control device can shut down the smart wearable device. This avoids the discharge voltage fluctuations of leaking batteries from affecting the normal operation of the smart wearable device, thus improving the operational stability of the smart wearable device.

[0056] If the result confirms that some batteries are leaking while the rest are normal, the control device can operate the smart wearable device in normal working mode. This involves shutting down the switching circuit connected to the leaking battery to stop its discharge, and turning on the switching circuit connected to the non-leaking batteries to allow the power management circuit to access the discharge voltage of each non-leaking battery to power on or continue operating the smart wearable device. The device will also alert the user to the presence of battery leakage and, after the alert, control the smart wearable device to continue operating. At this time, the control device can also use voice prompts and images to clearly indicate the location of each leaking battery among all the batteries, allowing the user or maintenance personnel to accurately pinpoint the location and speeding up the repair process.

[0057] Optionally, when the result indicates that some batteries are leaking while the rest are normal, the control device can further determine whether the total charge of the non-leaking batteries reaches a first preset charge threshold. If the first preset charge threshold is reached, it indicates that the total charge of the non-leaking batteries is still relatively high, and the control device can then control the smart wearable device to power on or operate normally. If the first preset charge threshold is not reached, it indicates that the total charge of the non-leaking batteries is relatively low, and the control device can then control the smart wearable device to operate in a low-power mode. In low-power mode, the control device can control the first type of functional components in the smart wearable device to operate normally and control the second type of functional components to stop operating. The first type of functional components can be those necessary for the smart wearable device to power on or operate, while the second type of functional components can be those not necessary for the smart wearable device to power on or operate.

[0058] Optionally, when the control device determines that the total charge of each non-leaking battery has not reached the first preset charge threshold, it may further determine whether the total charge of each non-leaking battery has reached the second preset charge threshold. The second preset charge threshold is less than the first preset charge threshold. If the second preset charge threshold is reached, it indicates that the total charge of each non-leaking battery is low, but not extremely low. In this case, the control device can control the first type of functional components to work in a low-power mode and control the second type of functional components to stop working. If the second preset charge threshold is reached, it indicates that the total charge of each non-leaking battery is extremely low. In this case, the control device can control the smart wearable device to work in a safe mode and then power off after prompting the user.

[0059] Optionally, the preset number of batteries can be one. In smart wearable devices, especially head-mounted smart wearable devices, if a single-battery power supply design is used, the battery is usually large, which not only increases the probability of leakage but also results in a larger volume of leakage that corrodes the device more quickly. By setting the preset number of batteries to one, the safety of smart wearable devices using a single-battery power supply design can be effectively improved.

[0060] Reference Figure 1 When it is determined that the number of batteries in the smart wearable device is not greater than a preset number, the working mode of the smart wearable device is determined to be the second working mode, and the smart wearable device is controlled to work according to the second working mode, and the smart wearable device is controlled to prompt the user that the smart wearable device has a battery leakage fault in a prompting manner that matches the second working mode.

[0061] In this embodiment, the second operating mode can be a safety mode. When the comparison result shows that the number of batteries in the battery compartment is less than or equal to a preset number, it indicates that the number of batteries in the compartment is low. At this time, regardless of whether the smart wearable device is powered on or off, the control device can control the smart wearable device to operate in safety mode, thereby controlling the opening of each switching circuit to provide power for the smart wearable device to power on or continue operating, and controlling the display screen or the audio-visual prompt circuit to issue corresponding prompt information to remind the user that there is battery leakage. After the prompt is completed, the control device can be turned off.

[0062] Optionally, the smart wearable device is controlled to operate according to the second operating mode, and the smart wearable device is controlled to prompt the user with a prompt method matching the second operating mode to indicate that the smart wearable device has a battery leakage fault. Specifically, the steps are as follows:

[0063] Control the display system of smart wearable devices;

[0064] The smart wearable device is controlled to work according to the second working mode, and the smart wearable device is controlled to prompt the user that the smart wearable device has a battery leakage fault in a prompting manner that matches the second working mode.

[0065] After being prompted, control the smart wearable device to shut down.

[0066] In this embodiment, the control device can still control the switching circuits corresponding to each battery to conduct, so that the power management circuit can access the discharge voltage of the leaking battery to power the display screen of the smart wearable device, enabling the display screen to display the system normally. Simultaneously, it can control the display screen or the audio-visual prompt circuit to continuously emit corresponding prompts within a preset time to alert the user that the device has a battery leakage fault, and can control the smart wearable device to shut down after the preset time. This allows the user to clearly understand that the reason the smart wearable device cannot be turned on is due to battery leakage protection, rather than damage to the smart wearable device system itself. Only the leaking battery needs to be replaced, effectively preventing users from mistakenly believing that the smart wearable device system is damaged and abandoning repairs, thus helping to extend the lifespan of the smart wearable device.

[0067] Reference Figure 2 Before step S100, which involves acquiring the concentration detection signal output by each concentration detection circuit, the battery leakage detection method further includes:

[0068] Step S300: Obtain the leakage detection trigger signal, and when the leakage detection trigger signal is received, control the smart wearable device to enter the battery leakage detection mode, and obtain the concentration detection signal output by each concentration detection circuit.

[0069] Optionally, the smart wearable device may include a leakage detection trigger circuit. The leakage detection trigger circuit can be implemented using trigger components such as function buttons or joysticks, and is not limited here; the leakage detection circuit can be connected to a control device so that when triggered, it outputs a leakage detection trigger signal to the control device to trigger the control device to start collecting the concentration detection signals output by each concentration detection circuit.

[0070] Optionally, the leakage detection trigger circuit can also be implemented using the power-on trigger circuit of the smart wearable device, that is, using the power-on trigger signal output by the power-on trigger circuit to realize the leakage detection trigger signal. In this way, the smart wearable device can automatically detect leakage of each battery at the same time as it is powered on, so as to ensure that the user can know the battery leakage status at the beginning of using the device, thereby avoiding the use of smart wearable devices with leaking batteries and further improving the safety of using smart wearable devices.

[0071] Furthermore, since the detection method of the present invention controls the working mode switching of the smart wearable device based on the number of batteries present after determining that battery leakage exists, it can save the startup time of the smart wearable device when there is no battery leakage, compared to determining the number of batteries present first, which is beneficial to improving the normal startup speed of the smart wearable device.

[0072] Reference Figure 3 Based on the detection signals of various organic matter concentrations, batteries in smart wearable devices that are leaking were identified, including:

[0073] The concentration of volatile organic compounds in the battery compartment where the corresponding concentration detection circuit is located is determined based on each temperature detection signal;

[0074] When the concentration of volatile organic compounds in at least one battery compartment reaches a preset concentration threshold, it is determined that there is a leaking battery in the smart wearable device.

[0075] The control device can perform analog-to-digital conversion on the input concentration detection signals to convert them into digital signals. Then, it analyzes and processes these signals to obtain the corresponding volatile organic compound (VOC) concentrations. The control device can compare the VOC concentration corresponding to each concentration detection signal with a preset concentration threshold and determine whether a leaking battery exists in the smart wearable device based on the comparison results. Specifically: if the comparison result shows that the VOC concentration corresponding to at least one concentration detection signal is greater than the preset concentration threshold, the control device determines that the VOC concentration in at least one battery compartment has reached the preset concentration threshold, indicating a leaking battery in the smart wearable device. If the comparison result shows that the VOC concentration corresponding to each concentration detection signal is not greater than the preset concentration threshold, the control device determines that the VOC concentration in no battery compartment has reached the preset concentration threshold, indicating no leaking battery in the smart wearable device. The preset concentration threshold can be obtained through numerous preset experiments and is not limited here.

[0076] In another embodiment, the preset concentration threshold can be selected as zero, so that the control device can detect the presence of battery leakage at an early stage and control the smart wearable device to alert the user, which helps to further improve the user's safety.

[0077] The present invention also proposes a control device for use in a smart wearable device. The smart wearable device includes at least one battery compartment, each battery compartment for assembling a battery, and is equipped with a concentration detection circuit. Each concentration detection circuit is used to detect the concentration of volatile organic compounds in its respective battery compartment and output a concentration detection signal.

[0078] Reference Figure 4 The control device includes:

[0079] Memory 410;

[0080] Processor 420;

[0081] The battery leakage detection program is stored in memory 410 and can run on processor 420. When processor 420 executes the battery leakage detection program, it implements the battery leakage detection method as described above.

[0082] In this embodiment, the specific steps of the battery leakage detection method are the same as those in the above embodiments. Since this control device adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, and will not be described in detail here.

[0083] The memory 410 can be a high-speed RAM or a stable memory (non-volatile memory), such as a disk storage device. Alternatively, the memory 410 can be a storage device independent of the aforementioned control device. The processor 420 can be a CPU. The memory 410 and the processor 420 are connected by a communication bus 430, which can be a UART bus or an I2C bus.

[0084] The present invention also proposes a smart wearable device, which includes at least one battery compartment and a control device. The specific structure of the control device is as described in the above embodiments. Since the smart wearable device adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0085] Reference Figure 5 and Figure 6 Each battery compartment 100 is used to assemble a battery 200 and is equipped with a concentration detection circuit 300. Each concentration detection circuit 300 is used to detect the concentration of volatile organic compounds (VOCs) in its respective battery compartment 100 and output a concentration detection signal. The concentration detection circuit 300 can be implemented using a VOC sensor. Each battery compartment 100 may have an opening communicating with the outside, allowing the battery 200 to be fed into the corresponding battery compartment 100 through the opening. Each battery compartment 100 opening may be covered by a battery compartment cover 500, and each battery compartment 100 opening may also be provided with a sealing ring 600 adapted to the shape of the opening, so that the battery compartment cover 500, after being covered, seals the battery 200 within the battery compartment 100 and the battery compartment cover 500 forming the battery 200 receiving cavity. The battery compartment covers 500 covering each battery compartment 100 may be separately arranged or integrally formed, which is not limited here. The concentration detection circuit 300 can be located in the gap between the battery 200 and the battery compartment 100. The control device can be connected to the output terminal of each concentration detection circuit 300 to receive the concentration detection signals output by each concentration detection circuit 300, and control the operation of the smart wearable device according to the received concentration detection signals.

[0086] Optionally, the smart wearable device is a head-mounted smart wearable device. By adopting the above-mentioned battery 200 leakage detection method, it is possible to effectively prevent battery 200 leakage from corroding the device and then entering the human body through the user's breathing during use, which is beneficial to improving the safety of using the head-mounted smart wearable device.

[0087] Optionally, the head-mounted smart wearable device is a head-mounted AR device or a head-mounted VR device.

[0088] Because users typically spend long periods of time using head-mounted AR or VR devices, and their movements are often large and their breathing rapid, if the battery 200 leaks and corrodes the device, users are highly susceptible to inhaling volatile organic compounds from the leaking battery 200 over extended periods. There is also a risk of the leaking battery 200 coming into contact with the user's eyes. The battery 200 leakage detection method of this invention can promptly alert users to battery 200 leakage and, when the number of batteries 200 is low, control the smart wearable device to shut down after the alert. This fundamentally prevents users from continuing to use head-mounted AR or VR devices with leaking batteries, greatly improving the safety of using these devices.

[0089] The above description is merely an optional embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
