Description

Technical Field

[0001] This application relates to the field of remote control technology, and in particular, to a remote controller and a pool robot. Background Art

[0002] In the prior art, when a remote controller using optical communication technology is used to control a pool robot, the optical emission module of the remote controller usually has a single working mode, and such a remote controller has low flexibility and poor adaptability. Summary of the Invention

[0003] This application provides a remote controller and a pool robot to solve the problems of low flexibility and poor adaptability of the remote controller in the prior art.

[0004] In a first aspect, an object of this application is to provide a remote controller, which includes: a remote control housing; a control module located in the remote control housing; an optical emission module connected to the control module; wherein, at least part of the optical emission module is exposed outside the remote control housing, and has a first working state and a second working state. After the optical emission module continuously works for a time longer than a first preset duration in the first working state, the optical emission module enters the second working state, and the optical emission module continuously works for a time longer than a second preset duration in the second working state.

[0005] The advantages of the above remote controller are as follows: The optical emission module of the remote controller can operate for corresponding durations in two working states respectively. On the one hand, since the optical emission module has two working states, compared with the prior art solution where the optical emission module only has one working state, the flexibility and adaptability of the remote controller are improved; on the other hand, since the optical emission module can switch between two working states and operate alternately in different working states, while ensuring the optical communication performance, the temperature rise of the optical emission module is effectively controlled, and the service life of the light source and electronic components is significantly extended. Further, the temperature rise of the control module can reduce errors and electromagnetic (EM) interference caused by overheating of the module. On the other hand, since the optical emission module is controlled to operate for different durations in different working states, a window is provided for system maintenance, self-checking, and redundant switching, enhancing the overall reliability of the system. In summary, the remote controller in the embodiments of this application has an optimized operation mechanism that takes into account performance, durability, and environmental protection.

[0006] Another object of this application is to provide a remote controller. In the first working state, the power range of the emission power of the optical emission module is 2W to 20W, the value range of the first preset duration is 1.5 minutes to 12 minutes, and the second preset duration is 1 minute.

[0007] The advantages of the above remote controller are as follows: The transmission power of the optical emission module in the first working state has an adjustable range of 2W to 20W. On the one hand, it ensures that the optical emission module can meet the requirements of underwater optical communication even at the lowest transmission power. On the other hand, it ensures that the remote controller will not overheat due to high-intensity work when the optical emission module is at the highest transmission power. Further, the value range of the first preset duration is any value between 1.5 minutes and 12 minutes. In this way, on the one hand, when the working duration of the optical emission module in the first working state exceeds this arbitrary value, such as exceeding 2 minutes, exceeding 3 minutes, exceeding 5 minutes, exceeding 10 minutes, etc., the optical emission module can switch to work in the second working state to trigger overheat protection and effectively reduce the risk of damage to electronic components. On the other hand, the first preset duration can be set in combination with the transmission power of the optical emission module, so as to realize different first preset durations corresponding to different transmission powers, enabling the remote controller to adapt to more application scenarios. Additionally, the second preset duration is 1 minute. In this way, when the working duration of the optical emission module in the second working state exceeds 1 minute, it enables the heat dissipation rate and heat generation rate inside the remote controller to achieve balance, thereby ensuring that the remote controller can operate stably and durably.

[0008] Another object of the present application is to provide a remote controller. In the first working state, the transmission power of the optical emission module is 6W, and the effective remote control distance of the optical emission module is 2.5m to 15m.

[0009] The advantages of the above remote controller are as follows: The optical emission module can use the 6W medium power mode to achieve a balance between energy consumption and transmission distance requirements, ensuring stable optical communication within the working environment and working range of the pool robot. At the same time, the effective remote control distance of the optical emission module can meet the short-distance precision control requirements of the remote controller for the pool robot, and can also meet the medium and long-distance control requirements of the remote controller for the moving pool robot.

[0010] Another object of the present application is to provide a remote controller, where the transmission power of the optical emission module in the first working state is greater than the transmission power of the optical emission module in the second working state.

[0011] The advantages of the above remote controller are as follows: After the optical emission module works for a preset duration at a relatively high transmission power, it can switch to a lower transmission power. On the one hand, when the optical emission module is at a lower transmission power, the heat generation rate is lower, which can not only reduce the dependence on the heat dissipation system but also prevent device aging caused by continuous high load. On the other hand, the high and low powers can respectively support the device to switch between modes such as remote control, sensing, and monitoring, so as to adapt to complex environments and diverse operation requirements.

[0012] Second aspect, an object of the present application is to provide a remote controller, the remote controller includes: a remote control housing; a control module located within the remote control housing; an optical emission module connected to the control module; wherein, the optical emission module is at least partially exposed outside the remote control housing and has a first working state and a second working state; the emission power of the optical emission module in the first working state is different from the emission power of the optical emission module in the second working state; the optical emission module is configured to operate in the first working state or the second working state in response to a working state indication signal sent by the control module, and in the first working state, the signal emitted by the optical emission module reaches the pool robot after passing through two media, and controls the pool robot to perform corresponding actions.

[0013] The advantages of the above remote controller are as follows: the optical emission module can operate in the first working state or the second working state according to the working state indication signal, that is, it can operate at a higher emission power and a lower emission power. On the one hand, since the optical emission module has two emission powers, compared with the prior art where the optical emission module only has one emission power, the flexibility and adaptability of the remote controller are improved; on the other hand, since the optical emission module has two emission powers, the optical signals emitted by the optical emission module at the two emission powers can adapt to two media with different transmission characteristics, enabling the remote controller to flexibly cope with the differential transmission requirements of optical signals in the two media. On the other hand, the optical emission module can switch between a higher emission power and a lower emission power, achieving the purpose of comprehensive optimization of the energy consumption, performance and reliability of the remote controller, especially suitable for the scenario where the remote controller collaborates with the pool robot to jointly cope with complex illumination and distance changes. The two different emission powers can adapt to the signal transmission conditions of the two media, increasing the flexibility and adaptability of the remote controller. Finally, the signal emitted by the optical emission module in the first working state can reach the pool robot after passing through two media, realizing high-efficiency communication between the remote controller and the pool robot in a cross-dual-media scenario, so that the remote controller can provide low-latency and highly reliable cross-environment remote control capabilities for the pool robot, suitable for real-time operation and status monitoring in complex scenarios.

[0014] Another object of the present application is to provide a remote controller, in the first working state, the signal emitted by the optical emission module reaches the pool robot after passing through a non-air medium, and controls the pool robot to perform corresponding actions.

[0015] The advantages of the above remote controller are as follows: the remote controller and the pool robot can be located in the same non-air medium, and the optical emission module has two emission powers. Thus, on the one hand, when the optical signal is transmitted in one medium, the signals with two different emission powers can be applied to different control instructions, improving the reliability of the signal; on the other hand, it can reduce the risk of overall communication interruption caused by the sudden change of the medium characteristics of the optical signal with a single power in the one non-air medium.

[0016] Another object of the present application is to provide a remote controller. In the first working state, the signal emitted by the light emission module reaches the pool robot after passing through at least three media, and controls the pool robot to perform corresponding actions.

[0017] The advantages of the above remote controller are as follows: The optical signal emitted by the light emission module can be transmitted in at least three media. In this way, the control requirements of various complex application scenarios are met. In addition, the light emission module has two emission powers, enabling the remote controller to flexibly respond when facing complex application scenarios where the optical signal needs to be transmitted in at least three media, thereby effectively improving the reliability of the optical signal.

[0018] Another object of the present application is to provide a remote controller, which further includes: a temperature detection module connected to the control module; wherein, the temperature detection module is used to detect the current temperature of the light emission module and output a temperature acquisition signal; the control module is used to respond to the temperature acquisition signal and output a working state indication signal.

[0019] The advantages of the above remote controller are as follows: On the one hand, the light emission module can work at different emission powers, improving the flexibility and adaptability of the remote controller; on the other hand, the light emission module can switch between a higher emission power and a lower emission power according to the current temperature of the light emission module detected by the temperature acquisition signal. This not only improves the penetration of the optical signal emitted by the light emission module, thereby enhancing the communication quality, performance, and stability between the remote controller and the pool robot, but also reduces the heat generated by the light emission module, reducing the possibilities of accelerated aging, failure, or burnout caused by continuous heating during long-term high-power operation of the light emission module, thus realizing the over-temperature protection function of the remote controller and further achieving an optimal balance between temperature and performance. In addition, in the prior art, a heat dissipation device such as a fan is usually used to dissipate heat from the over-temperature remote controller. This method has a complex structural design, poor heat dissipation efficiency, and generally a long waiting time between shutdown after over-temperature and the next startup. However, in this solution, by switching the emission power of the light emission module to a lower emission power, heat dissipation of the over-temperature remote controller can be achieved without setting a fan. Therefore, the overall structure of this solution is simple and the volume is small.

[0020] Another object of the present application is to provide a remote controller, wherein the working state indication signal includes a first working state indication signal and a second working state indication signal; the optical emission module includes an optical emitter, at least a part of which is exposed outside the remote control housing; wherein, the optical emitter is configured to emit an optical signal with a first optical power in response to the first working state indication signal, so that the optical emission module is in the first working state; or, emit an optical signal with a second optical power in response to the second working state indication signal, so that the optical emission module is in the second working state; the first optical power is different from the second optical power.

[0021] The advantages of the above remote controller are as follows: different working state indication signals are used to drive the optical emitter to emit optical signals with different optical powers, so as to adjust the emission power of the optical emission module. This can not only directly improve the penetration of the optical signal emitted by the optical emitter, thereby enhancing the communication quality, performance and stability between the remote controller and the pool robot, but also improve the hardware integration of the circuit structure between the control module and the optical emission module, and enhance the signal reliability.

[0022] Another object of the present application is to provide a remote controller, which further includes: a first power adjustment circuit including a first branch and a second branch connected in parallel, and the control module is connected to the optical emission module through the first branch and the second branch; the first branch includes a first resistor, and the first power adjustment circuit enables the optical emission module to be in the first working state through the first resistor; the second branch includes a second resistor, and the first power adjustment circuit enables the optical emission module to be in the second working state through the second resistor; the resistance values of the first resistor and the second resistor are different.

[0023] The advantages of the above remote controller are as follows: the first power adjustment circuit adjusts the emission power of the optical emission module through the first branch and the second branch which are connected in parallel and have different resistance values. In this way, the circuit structure has the characteristics of simple design and easy implementation, so that the remote controller can be realized with low cost and have an over-temperature protection function.

[0024] Another object of the present application is to provide a remote controller, wherein the control module has a first pin and a second pin; the first pin is connected to the first branch; the second pin is connected to the second branch.

[0025] The advantages of the above remote controller are as follows: the control module is respectively connected to the first branch and the second branch through two different pins, and the first branch and the second branch are more independent, making the process of adjusting the emission power of the optical emission module more flexible, so as to meet different application requirements.

[0026] Another object of the present application is to provide a remote controller, wherein the first power adjustment circuit includes a circuit main body; the circuit main body has an input end and an output end; the input end is connected to the control module; the output end is respectively connected to the first branch and the second branch.

[0027] The advantages of the above remote control are as follows: The main circuit body is connected to the first branch and the second branch through the output end. Both the first branch and the second branch can use the electrical signals processed by the main circuit body. In this way, only one main circuit body is needed, and electrical signals that can be used by the two branches can be obtained, effectively reducing the hardware cost.

[0028] Another object of the present application is to provide a remote control, which further includes: a second power adjustment circuit, respectively connected to the light emission module and the control module; within each pulse period, the second power adjustment circuit adjusts the working state indication signal, the working state indication signal has a first duty cycle, and the emission duration of the light emission module in the first working state corresponds to the working state indication signal with the first duty cycle; or, within each pulse period, the second power adjustment circuit adjusts the working state indication signal, the working state indication signal has a second duty cycle, and the emission duration of the light emission module in the second working state corresponds to the working state indication signal with the second duty cycle, and the first duty cycle is different from the second duty cycle.

[0029] The advantages of the above remote control are as follows: The second power adjustment circuit can adjust the electrical signal driving the light emission module to have a first duty cycle or a second duty cycle, so as to control the emission power of the light emission module and meet different application requirements.

[0030] Another object of the present application is to provide a remote control, a light emission module, which is used to switch from the first working state to the second working state when the current temperature of the light emission module is greater than or equal to the first temperature threshold; wherein, the emission power of the light emission module in the first working state is greater than the emission power of the light emission module in the second working state.

[0031] The advantages of the above remote control are as follows: The light emission module can switch from the first working state with a higher emission power to the second working state with a lower emission power, thereby reducing the heat generated by the light emission module, effectively reducing the probability of the remote control overheating, and switching to a lower power when overheating can reduce the waiting time of the user.

[0032] Another object of the present application is to provide a remote control, a light emission module, which is used to stop working if the temperature of the light emission module is greater than or equal to the first temperature threshold after a third preset duration when the light emission module switches from the first working state to the second working state.

[0033] The advantages of the above remote control are as follows: The light emission module can switch from the second working state with a lower emission power to stop working, so that the light emission module stops generating heat, effectively reducing the probability of the remote control overheating.

[0034] Another object of the present application is to provide a remote controller, an optical emission module, which is configured to switch from a second working state to a first working state when the current temperature of the optical emission module is less than a second temperature threshold; wherein the second temperature threshold is less than or equal to the first temperature threshold.

[0035] The advantage of the above remote controller is that: when the preset temperature condition is met, the optical emission module can switch from the second working state with a lower emission power to the first working state with a higher emission power. In this way, although a certain amount of heat will be generated, the quality of the optical signal emitted by the optical emission module can be improved, the performance of the optical emission module can be optimized, and specific application requirements can be met.

[0036] Another object of the present application is to provide a remote controller, an optical emission module, which is configured to, when the current temperature of the optical emission module is greater than or equal to the first temperature threshold and the optical emission module stops working, if the temperature of the optical emission module is less than a third temperature threshold after a fourth preset duration, the optical emission module is in the second working state; wherein the third temperature threshold is less than the first temperature threshold.

[0037] The advantage of the above remote controller is that: when the optical emission module overheats in the first working state with a higher emission power and triggers the optical emission module to stop working, if the optical emission module can cool down to the preset temperature within the preset duration, the optical emission module can start working in the second working state with a lower emission power, so that the waiting time of the user can be reduced.

[0041] The advantage of the above remote controller is that: the negative temperature coefficient thermistor or the positive temperature coefficient thermistor has high sensitivity, high precision, fast response and good stability, so as to meet the requirements of temperature detection.

[0055] In the following description, specific details such as specific system structures and technologies are presented for the purpose of illustration rather than limitation, so as to thoroughly understand the embodiments of the present application. However, those skilled in the art should clearly understand that the present application can also be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to avoid unnecessary details from interfering with the description of the present application.

[0056] In order to illustrate the technical solutions described in the present application, the following will be described through specific embodiments.

[0057] The embodiments of the present application provide a remote controller and a pool robot to solve the problems of low flexibility and poor adaptability of existing remote controllers in complex application scenarios.

[0058] In a first aspect, the embodiments of the present application provide a remote controller.

[0059] Figure 1 is a schematic diagram of an application scenario of a remote controller provided by the embodiments of the present application. Refer to Figure 1 As shown, the pool robot 30 is an intelligent cleaning device that can drive a cleaning brush, a sewage suction system, and a filtering device through an electric motor, and can autonomously complete the cleaning tasks of the bottom, wall, and water line of the pool. The remote controller 10 is used for real-time control and task management of the pool robot, and has functions such as navigating the pool robot and collaborating with obstacles to avoid obstacles.

[0060] When the pool robot 30 and the remote controller 10 work together, the pool robot 30 can be located in the pool, and the water in the pool can submerge the pool robot 30. The remote controller 10 can be located outside the pool for easy use by the user. The communication between the pool robot 30 and the remote controller 10 can use optical communication technology for communication.

[0061] In some embodiments, when the remote controller 10 using optical communication technology controls the pool robot 30, the optical emission module of the remote controller 10 usually has only one working state, and there is a fixed emission power corresponding to this working state, resulting in low flexibility and poor adaptability of the remote controller.

[0062] For example, in order to improve the penetration of the optical signal emitted by the optical emission module, the optical emission module with only one working state can work at a relatively high emission power. However, long-term high-power operation will cause the optical emission module to age rapidly due to continuous heating, and even malfunction or burn out. In order to reduce power consumption, the optical emission module with only one working state can work at a relatively low emission power. However, the relatively low emission power will reduce the intensity of the signal emitted by the optical emission module, which is not conducive to the communication connection between the remote controller 10 and the pool robot 30, thus making the remote controller 10 unable to accurately control the pool robot 30.

[0063] Based on the above application scenarios, Figure 2 FIG. is a schematic diagram of the hardware structure of a remote controller provided by an embodiment of the present application. Figure 3 FIG. is a schematic diagram of the circuit structure of a remote controller provided by an embodiment of the present application. Refer to Figures 1 to 3 As shown, the remote controller 10 may include: a remote control housing 11, a control module 12, and an optical emission module 13. The control module 12 is located inside the remote control housing 11. The control module 12 is connected to the optical emission module 13, and at least part of the optical emission module 13 is exposed outside the remote control housing 11.

[0064] In some embodiments, the remote control housing 11 has the functions of protecting the internal circuit components of the remote controller, providing necessary structural support, and shielding visible light and other unnecessary electromagnetic wave interferences. The material forming the remote control housing 11 may be polypropylene (PP), polycarbonate (PC), acrylonitrile butadiene styrene plastic (ABS plastic), etc.

[0065] In one embodiment, the remote control housing 11 may be composed of an upper housing and a lower housing. The upper housing generally may include a button area and a display screen, while the lower housing may include a battery compartment part. An upper snap plate is provided at the opening of the upper housing, and a lower snap plate is provided at the opening of the lower housing. The upper snap plate and the lower snap plate are snapped together to realize the closing of the remote control housing 11. After the remote control housing 11 is closed, an accommodation space is formed inside to accommodate the control module 12 and the optical emission module 13.

[0066] In some embodiments, a notch may be formed on the remote control housing 11, and the notch is used to at least partially expose the light emitting module 13. In one embodiment, the notch may be a gap generated during the fastening process of the upper housing and the lower housing.

[0067] In some embodiments, when the light emitting module 13 operates, it can convert electrical energy (electrical signal) into an optical signal and transmit the optical signal to a remote device (such as a pool machine). In this way, the remote control 10 can remotely control the remote device.

[0068] In some embodiments, the light emitting module 13 may include a light emitting element. When the light emitting element is driven by an electrical signal, it emits an optical signal to the remote device. In some embodiments, the light emitting element may be an element that emits visible light or invisible light. In some embodiments, the light emitting module 13 may further include a light emitting driving circuit. The light emitting driving circuit may be connected to the light emitting element and is used to provide an electrical signal to the light emitting element to drive the light emitting element to emit an optical signal.

[0069] In some embodiments, the light emitting module 13 has a first working state and a second working state, and the first working state is different from the second working state.

[0070] In some embodiments, the emission power of the light emitting module 13 in the first working state may be different from the second emission power of the light emitting module 13 in the second working state. Among them, the emission power may be the power consumed when the light emitting module 13 emits an optical signal.

[0071] It can be understood that when the light emitting module 13 operates in the first working state, the emission power of the light emitting module 13 may be the first emission power, and when the light emitting module 13 operates in the second working state, the emission power of the light emitting module 13 may be the second emission power. Since the first emission power is different from the second emission power, compared with the prior art solution in which the light emitting module only has one emission power, the flexibility and adaptability of the remote control are improved.

[0072] In some embodiments, the emission power of the light emitting module 13 in the first working state can be set according to actual needs. In some embodiments, the second emission power of the light emitting module 13 in the second working state can also be set according to actual needs.

[0073] In some embodiments, the light emitting module 13 may consume different electrical energies in the first working state and the second working state. Correspondingly, the light emitting module 13 may generate different heats in the first working state and the second working state.

[0074] In some embodiments, the control module 12 outputs a working state indication signal to the optical emission module 13. The optical emission module 13 is driven by the working state indication signal and operates in a first working state or a second working state. In this way, after the continuous working time in the first working state is greater than a first preset duration, the optical emission module 13 enters the second working state, and the continuous working time of the optical emission module 13 in the second working state is greater than a second preset duration.

[0075] It can be understood that the control module 12 can output a working state indication signal to the optical emission module 13. The optical emission module 13 is driven by the working state indication signal and operates for a certain duration in the first working state or the second working state. Further, the optical emission module 13 is driven by the working state indication signal. After the continuous working time in the first working state is greater than the first preset duration, it can switch to the second working state and continuously work for a time greater than the second preset duration in the second working state. In this way, the optical emission module 13 can be switched from the first working state to the second working state.

[0076] It can be understood that when the optical emission module 13 is switched from the first working state to the second working state, the emission power of the optical emission module 13 can be changed, so as to realize the joint optimization of energy consumption and communication performance and adapt to complex application scenarios and diverse operation requirements.

[0077] Exemplarily, the emission power of the optical emission module 13 in the first working state can be a first value, and the emission power of the optical emission module 13 in the second working state can be a second value. When the first value is greater than the second value and the second value is not zero, the optical emission module 13 can be switched from a higher emission power to a lower emission power. In this way, while ensuring the optical communication performance, the low-power consumption requirement can be realized. When the first value is greater than the second value and the second value is zero, the optical emission module 13 can be switched from a higher emission power to stop working. In this way, the continuous temperature rise of the optical emission module 13 in the first working state can be effectively controlled, and the service life of the light source and electronic components can be significantly extended. When the first value is less than the second value and the first value is zero, the optical emission module 13 can be switched from stop working to working. In this way, it can be ensured that the remote controller 10 can be actively started, so as to increase the connection duration with the pool robot 30 and meet the user's usage requirements. When the first value is less than the second value and the first value is not zero, the optical emission module 13 can be switched from a lower emission power to a higher emission power. In this way, the strong signal communication requirement between the pool robot 30 and the optical emission module 13 can be met, and the remote control performance can be improved.

[0078] In some embodiments, when the light-emitting module 13 switches from the first working state to the second working state, over-temperature protection of the remote controller 10 can be achieved. In one embodiment, the control module 12 can first determine an over-temperature protection point. Subsequently, according to the correlation between the over-temperature protection point and parameters such as the emission power, emission duration, and effective remote control distance of the light-emitting module 13, parameters such as the emission power of the light-emitting module 13 in the first working state, the emission power of the light-emitting module 13 in the second working state, the first preset duration, and the second preset duration are determined. Finally, the light-emitting module 13 is controlled according to the determined parameters to achieve over-temperature protection of the remote controller 10.

[0079] Exemplarily, taking 75 °C (Celsius) as the over-temperature protection point as an example, it is described how to determine whether over-temperature protection is triggered in the continuous use state of the remote controller (equivalent to the first working state). First, selecting 75 °C as the over-temperature protection point has at least the following four advantages:

[0080] First, meeting the safety performance requirements: 75 °C is lower than the plastic softening temperature (90 °C) and the semiconductor junction temperature (125 °C), which can ensure the stable use of both the remote control housing 11 and the light-emitting module 13.

[0081] Second, good user experience: On the one hand, when the temperature inside the remote controller 10 is 75 °C, the surface temperature of the remote control housing 11 can still be ensured to be less than or equal to 48 °C, thus avoiding low-temperature burns to users. On the other hand, historical usage data shows that the daily trigger probability when the temperature inside the remote controller 10 reaches 75 °C is relatively small. Therefore, setting 75 °C as the over-temperature protection point will not cause frequent protection shutdowns and affect user use.

[0082] Third, good environmental compatibility performance: In the environmental temperature range of -20 °C to +50 °C, using 75 °C as the over-temperature protection point can effectively protect the light-emitting module 13 from damage.

[0083] Fourth, good benefits and low cost: The Bill of Materials (BOM) cost is reduced by 15 - 30% compared to the solutions with over-temperature protection points of 65 °C or 85 °C, and the mass production yield > 99.2%.

[0084] Secondly, according to the over-temperature protection point being 75 °C, the control module 12 can determine the performance of the remote controller. In one embodiment, Table 1 shows a possible performance of the remote controller when the over-temperature protection point is 75 °C.

[0085] Table 1

[0086]

[0087] As can be seen from Table 1 above, the control module 12 can determine that the emission power of the light emission module 13 in the first working state should not be greater than 20W. Because a power above 20W cannot meet the daily application requirements of users. The control module 12 can determine that the emission power of the light emission module 13 in the first working state should not be less than 2W. Since the scenario of this application is to control the pool robot 30 through the remote controller 10, when the pool robot 30 is below the liquid level, when the power of the remote controller is less than 2W, the signal emitted by the remote controller 10 cannot be effectively transmitted in the liquid.

[0088] Further, the control module 12 can determine that the power range of the emission power of the light emission module 13 is 2W to 20W. Because as the emission power of the light emission module 13 of the remote controller 10 increases, the maximum depth of the supported pool (i.e., the vertical distance between the pool robot and the water surface) is greater. However, at the same time, as the emission power increases, the time to trigger over-temperature protection is shorter. Based on the dual requirements of balancing the remote control distance and triggering over-temperature protection, the power range of the emission power of the light emission module 13 in this application can be 2W to 20W. In one embodiment, the emission power of the light emission module 13 is 2W, and the remote controller 10 is applicable to small pools. In one embodiment, the emission power of the light emission module 13 is 20W, and the remote controller 10 is applicable to the emergency rescue mode (such as scenarios of out-of-control in long-distance / complex environments, emergency manual intervention requirements, extreme safety protection, etc.).

[0089] In some embodiments, the power range of the emission power of the light emission module 13 in the first working state is 2W to 20W, which may include: the emission power of the light emission module 13 in the first working state is fixed at any value between 2W and 20W. In some embodiments, the power range of the emission power of the light emission module 13 in the first working state is 2W to 20W, which may include: the emission power of the light emission module 13 in the first working state is dynamically adjusted between 2W and 20W.

[0090] Further, the control module 12 can determine that the value range of the first preset duration can be from 1.5 minutes to 12 minutes according to the power range of the light emission module 13 in the first working state and the time for triggering over-temperature protection at different powers. In this way, on the one hand, when the working duration of the light emission module 13 in the first working state exceeds any of these values, such as exceeding 2 minutes, 3 minutes, 5 minutes, 10 minutes, etc., the light emission module 13 can switch to the second working state to trigger over-temperature protection, effectively reducing the risk of damage to electronic components. On the other hand, the first preset duration can be set in combination with the emission power of the light emission module 13, so as to achieve different first preset durations corresponding to different emission powers, enabling the remote control to adapt to more application scenarios. For example, when the emission power of the light emission module 13 selects the maximum emission power of 20W, the control module 12 can determine that the light emission module 13 only needs to continuously work for more than 1.5 minutes in the first working state to switch to the second working state; when the emission power of the light emission module 13 selects the minimum emission power of 2W, the control module 12 can determine that the light emission module 13 needs to continuously work for more than 12 minutes in the first working state to switch to the second working state. In this way, the dynamic matching of the emission power and the first preset duration is realized, and the continuous working time of the light emission module 13 in the first working state is increased as much as possible. When the first working state is the main working state for the remote control 10 to control the pool robot to perform corresponding actions, by increasing the continuous working time of the light emission module 13 in the first working state, the performance of the remote control 10 can be effectively improved.

[0091] Further, the control module 12 can determine that the second preset duration is 1 minute. In this way, the light emission module 13 can be forced to continuously work for at least 1 minute at a lower emission power, achieving effective heat dissipation, balancing the heat generation efficiency and heat dissipation efficiency of the remote control 10, and maintaining the stability of the remote control 10 system.

[0092] In some embodiments, the control module 12 can determine that the emission power of the light emission module 13 in the first working state can be 6W. In this way, when there is no obstruction between the remote control 10 and the pool robot 30 in a simple scenario, the light emission module 13 can achieve an effective remote control distance of 15m. During the multi-media transmission process between the remote control 10 and the pool robot 30, it can achieve an effective remote control distance of at least 2.5m, thereby ensuring stable optical communication of the remote control 10 within the working environment and working range of the pool robot.

[0093] In some embodiments, the emission power of the light emission module 13 in the first working state can be greater than the emission power in the second working state. In this way, when the light emission module 13 switches from the first working state to the second working state, it can better achieve over-temperature protection of the remote control 10.

[0094] In one embodiment, the emission power of the optical emission module 13 in the first working state ranges from 2W to 20W. Alternatively, when the emission power of the optical emission module 13 in the first working state is 6W, the emission power of the optical emission module 13 in the second working state is less than 6W, and the emission power of the optical emission module 13 in the first working state is greater than that in the second working state. Thus, the balance between dynamic power consumption and control requirements can be achieved.

[0095] In some embodiments, the optical emission module 13 can be switched from the second working state to the first working state. Exemplarily, the optical emission module 13 can be driven by a working state indication signal. After the continuous working time in the second working state is greater than a second preset duration, the optical emission module 13 enters the first working state, and the continuous working time of the optical emission module 13 in the first working state is greater than a first preset duration.

[0096] It can be understood that the optical emission module 13 is driven by a working state indication signal. After the continuous working time in the second working state is greater than the second preset duration, it can be switched to the first working state and continuously work in the first working state for a time greater than the first preset duration. Thus, the optical emission module 13 can be switched from the second working state to the first working state.

[0097] It can be understood that when the optical emission module 13 can be switched from the first working state to the second working state and from the second working state to the first working state, the optical emission module 13 can operate alternately in the first working state and the second working state. Thus, while ensuring the underwater optical communication performance, the temperature rise of the optical emission module 13 can be effectively controlled, and the service life of the light source and electronic components can be significantly extended. At the same time, the communication stability and reliability of the system are improved, the energy consumption and environmental thermal interference are reduced, the use safety and operation experience are improved, and the hidden risks such as bit errors, electromagnetic interference, and underwater disturbances are reduced.

[0098] In a second aspect, an embodiment of the present application provides a remote controller.

[0099] Still referring to Figures 1 to 3 As shown, the remote controller 10 may include: a remote control housing 11, a control module 12, and an optical emission module 13. The control module 12 is located inside the remote control housing 11. The control module 12 is connected to the optical emission module 13, and at least a part of the optical emission module 13 is exposed outside the remote control housing 11. Among them, the structure of the optical emission module 13 may be the same as that of the optical emission module 13 described in any embodiment of the first aspect. The structure of the remote control housing 11 may be the same as that of the remote control housing 11 described in any embodiment of the first aspect.

[0100] In some embodiments, the light emission module 13 has a first operating state and a second operating state. The emission power of the light emission module 13 in the first operating state is different from the second emission power of the light emission module 13 in the second operating state. In some embodiments, the emission power of the light emission module 13 in the first operating state and the second emission power of the light emission module 13 in the second operating state are both non-zero.

[0101] It can be understood that when the light emission module 13 operates in the first operating state, the emission power of the light emission module 13 can be the first emission power, and when the light emission module 13 operates in the second operating state, the emission power of the light emission module 13 can be the second emission power. Since the first emission power is different from the second emission power, the light emission module 13 consumes different amounts of electrical energy in the first operating state and the second operating state. Correspondingly, the light emission module 13 generates different amounts of heat in the first operating state and the second operating state.

[0102] In some embodiments, the above-mentioned first emission power and second emission power can be determined according to the actual application scenarios and requirements, and the embodiments of the present application do not make specific limitations thereto. In one example, the first emission power can be greater than the second emission power. The first emission power can be 6W, and the second emission power can be 4W; in one example, the first emission power can be less than the second emission power. The first emission power can be 3W, and the second emission power can be 4W.

[0103] In some embodiments, the control module outputs a working state indication signal to the light emission module 13. The light emission module 13 is driven by the working state indication signal to operate in the first operating state or the second operating state. In the first operating state, the signal emitted by the light emission module 13 reaches the pool robot after passing through two media to control the pool robot 30 to perform corresponding actions.

[0104] It can be understood that the control module 12 can send a working state indication signal to the light emission module 13. The light emission module 13 is driven by the working state indication signal to operate in the first operating state or the second operating state. Further, the light emission module 13 can be driven by the working state indication signal to switch between the first operating state and the second operating state.

[0105] It can be understood that the working state indication signal can enable the light emission module 13 to be in two operating states. Assume that the light emission module 13 operates in the first operating state. When the control module 12 outputs a working state indication signal to the light emission module 13, the light emission module 13 can be driven by the working state indication signal to operate in the second operating state. In this way, the light emission module 13 can be switched from the first operating state to the second operating state. Similarly, the light emission module 13 can also be switched from the second operating state to the first operating state.

[0106] It is understandable that the optical emission module 13 can at least emit optical signals at different emission powers under the drive of the control module 12, which can improve the adaptability of the remote controller 10. For example: 1. Dynamic energy-saving optimization. The remote controller 10 can adjust the energy consumption level according to real-time requirements (such as operating at a lower emission power during standby / low load and at a higher emission power when issuing high-intensity control instructions), reduce ineffective energy loss, and extend the battery life of the remote controller. 2. Enhanced environmental adaptability. In the presence of strong light interference (such as sunlight directly shining on the water surface) or in a long-distance scenario, switch to a higher emission power to improve signal penetration; in a short-distance or weak interference environment, switch to a lower emission power to avoid problems such as multipath reflection caused by signal overload and ensure communication stability. 3. Extended device life. By dynamically adjusting the working load of the optical emission module 13, the risk of hardware loss is reduced. 4. Improved anti-interference ability. By combining a photosensitive sensor (such as a photoresistor to continuously monitor the ambient light intensity) with a feedback control logic, the impact of external interference signals on the optical communication link can be offset through power adjustment, reducing the bit error rate.

[0107] It is understandable that the optical emission module 13 generates different amounts of heat in the first working state and the second working state. When the optical emission module 13 can switch between the first working state and the second working state, it can be realized that the optical emission module 13 switches from the working state with more heat generation to the working state with less heat generation. In this way, it is possible to reduce the heat accumulated inside the remote controller 10 and reduce the probability of the remote controller 10 overheating. When the optical emission module 13 can switch between the first working state and the second working state, it can also be realized that the optical emission module 13 switches from the working state with less heat generation to the working state with more heat generation. In this way, although the heat generated by the remote controller 10 increases, the working state with more heat generation can correspondingly generate optical signals with higher intensity, thereby improving the communication connection performance between the remote controller 10 and the pool robot 30.

[0108] It can be understood that in the first working state, the optical signal emitted by the optical emission module 13 can reach the pool robot 30 through two media, and the pool robot 30 receives the reached optical signal. In this way, the communication connection between the pool robot 30 and the remote controller 10 is realized. It can be seen that in the embodiment of the present application, efficient communication between the remote controller and the pool robot in a cross-dual-media scenario is achieved, so that the remote controller can provide the pool robot with low-latency and highly reliable cross-environment remote control capabilities, which are suitable for real-time operation and status monitoring in complex scenarios. Further, the remote controller 10 can switch the emission power of the optical emission module 13 while communicating with the pool robot 30 across media and at a long distance, which enables the remote controller 10 to implement an over-temperature protection function or enhance the communication connection performance between the remote controller 10 and the pool robot 30. In addition, since the optical emission module has two emission powers, the optical signals emitted by the optical emission module at the two emission powers can adapt to two media with different transmission characteristics, so that the remote controller can flexibly cope with the differential transmission requirements of the optical signals in the two media.

[0109] In some embodiments, the two media in the first working state may be water and air. In some embodiments, the two media in the first working state may also be other media combinations, and the embodiments of the present application do not limit this.

[0110] In some embodiments, the control module 12 may include: a control circuit. The control circuit can receive a control signal and output a working state indication signal to the optical emission module.

[0111] It can be understood that the control circuit is used to generate a working state indication signal according to the control signal and send the working state indication signal to the optical emission module 13. Here, the specific implementation of the control signal can be set according to actual needs, and the embodiments of the present application do not make specific limitations on this.

[0112] In some embodiments, the control signal may be a control instruction input by the user. In some embodiments, the control signal may be a control instruction executed by the system by default.

[0113] It can be understood that when the user inputs a first instruction, the control circuit can generate a working state indication signal with a first voltage value according to the first instruction, and the working state indication signal can drive the optical emission module 13 to work in the first working state; when the user inputs a second instruction, the control circuit can generate a working state indication signal with a second voltage value according to the second instruction, and the working state indication signal can drive the optical emission module 13 to work in the second working state.

[0114] In some embodiments, different current values, level values, etc. of the working state indication signal can also drive the optical emission module 13 to work in different working states.

[0115] It should be noted that the working state indication signals described in any embodiment of the second aspect and the working state indication signals described in any embodiment of the first aspect are both used to control the optical emission module 13 to work in the first working state or the second working state. In this way, the circuit structures between the control module 12 and the optical emission module 13 in any remote controller provided in the embodiments of the present application can be the same.

[0116] In some embodiments, the specific structure and preset circuit logic of the control circuit can be set according to actual needs, and the embodiments of the present application do not limit this. In some embodiments, the control circuit may be an integrated circuit. In some embodiments, the control circuit may be a digital circuit. In some embodiments, the control circuit may be packaged as a microprocessor or a microcontroller. In some embodiments, the control circuit may be a programmable logic unit. For example, the control circuit may be a field programmable gate array (FPGA).

[0117] In some embodiments, the control module 12 may further include: a communication interface. The communication interface is connected to the control circuit. The control circuit can output the working state indication signal to the optical emission module 13 through the communication interface. In some embodiments, the type of the communication interface may include a wired interface (such as an I²C bus (inter integrated circuit bus), a serial peripheral interface (SPI), etc.) or a wireless interface (such as Wi-Fi, Bluetooth, etc.), which depends on the design and requirements of the system.

[0118] In the embodiments of the present application, the optical emission module can work at a higher emission power and a lower emission power according to the working state indication signal. On the one hand, since the optical emission module has two emission powers, compared with the prior art in which the optical emission module only has one emission power, the flexibility and adaptability of the remote controller are improved; on the other hand, since the optical emission module has two emission powers, the optical signals emitted by the optical emission module at the two emission powers can adapt to two media with different transmission characteristics, enabling the remote controller to flexibly respond to the differential transmission requirements of optical signals in the two media. On the other hand, the optical emission module can switch between a higher emission power and a lower emission power, realizing intelligent power management and achieving the comprehensive optimization of the energy consumption, performance, and reliability of the remote controller, especially suitable for the scenario where the remote controller cooperates with the pool robot to jointly cope with complex light and distance changes.

[0119] In some possible implementation manners, still referring to Figures 1 to 3As shown, in the first working state, the signal emitted by the optical emission module 13 reaches the pool robot 30 after passing through a non-air medium, and controls the pool robot 30 to perform corresponding actions.

[0120] It can be understood that the remote controller 10 and the pool robot 30 can be located in the same non-air medium. In the first working state, the optical signal emitted by the optical emission module 13 in the remote controller 10 can reach the pool robot 30 after passing through the non-air medium, and controls the pool robot 30 to perform corresponding actions.

[0121] It can be understood that when the optical signals emitted by the optical emission module 13 at two emission powers are transmitted in a non-air medium, on the one hand, the signals at two different emission powers can be applied to different control instructions, improving the reliability of the signals; on the other hand, it can reduce the risk of overall communication interruption caused by the sudden change of the medium characteristics of the optical signal at a single power in the non-air medium.

[0122] In some embodiments, in the first working state, the non-air medium through which the optical signal emitted by the optical emission module 13 passes can be water. In some embodiments, the non-air medium can be water or other non-air media, such as petroleum, and the embodiments of the present application do not make any limitations in this regard.

[0123] In some possible implementation manners, still referring to Figures 1 to 3 As shown, in the first working state, the signal emitted by the optical emission module 13 reaches the pool robot 30 after passing through at least three media, and controls the pool robot 30 to perform corresponding actions.

[0124] It can be understood that in the first working state, there can be at least three media between the remote controller 10 and the pool robot 30. The optical signal emitted by the optical emission module 13 in the remote controller 10 can reach the pool robot 30 after passing through the at least three media, and controls the pool robot 30 to perform corresponding actions.

[0125] It can be understood that the optical signal emitted by the optical emission module 13 can be transmitted in at least three media. In this way, the control requirements of various complex application scenarios are met. In addition, the optical emission module 13 has two emission powers, enabling the remote controller 10 to flexibly respond when facing complex application scenarios where the optical signal needs to be transmitted in at least three media, thereby effectively improving the reliability of the optical signal.

[0126] In some embodiments, in the first working state, the at least three media through which the optical signal emitted by the optical emission module 13 passes can include: water, air, and petroleum. In some embodiments, the at least three media can also be other media combinations, and the embodiments of the present application do not make any limitations in this regard.

[0127] In some possible embodiments, Figure 4 is a schematic circuit diagram of a remote controller provided by an embodiment of the present application. Refer to Figure 4 As shown, the remote controller 10 may further include: a temperature detection module 14. The temperature detection module 14 is located inside the remote control housing 11 and is connected to the control module 12.

[0128] In some embodiments, the temperature detection module 14 outputs a temperature acquisition signal to the control module 12, and the temperature acquisition signal can represent the current temperature (i.e., the real-time temperature) of the light emission module 13. The control module responds to the temperature acquisition signal and outputs a working state indication signal to the light emission module 13.

[0129] It can be understood that the control module 12 is respectively connected to the light emission module 13 and the temperature detection module 14, so as to enable the transmission of electrical signals between the control module 12, the light emission module 13, and the temperature detection module 14. Specifically, after detecting the current temperature of the light emission module 13, the temperature detection module 14 can send a temperature acquisition signal to the control module 12. After receiving the temperature acquisition signal, the control module 12 can generate a working state indication signal in response to the temperature acquisition signal and send the working state indication signal to the light emission module 13. The light emission module 13 works in the first working state or the second working state under the drive of the working state indication signal. The signal emitted by the light emission module reaches the pool robot after passing through at least one medium, so as to control the pool robot to perform corresponding actions.

[0130] It can be understood that the control signal input to the control module 12 can be a temperature acquisition signal. In this way, it is possible to control the light emission module 13 to work in the first working state or the second working state based on the current temperature of the light emission module 13. Then, at least when the current temperature of the light emission module 13 is relatively high, it is possible to control the light emission module 13 to work in a working state with a lower emission power.

[0131] It can be understood that the light emission module in the optical communication remote controller can convert electrical energy into optical signals. In this conversion process, only a small part of the electrical energy can be converted into optical signals, and most of the electrical energy will be converted into heat, which causes heat to accumulate inside the remote controller. At the same time, due to limitations such as appearance and cost, the housing of the remote controller mostly uses plastic materials, and the internal space is limited. The thermal conductivity of plastic is relatively low, which is not conducive to the dissipation of the heat accumulated inside the remote controller, resulting in the remote controller being prone to over-temperature phenomena and affecting the service life of the light emission module. Especially when the remote controller is applied to cross-media and long-distance communication requirements and continuous communication requirements, it is often necessary for the light emission module to work in a high-power mode or continuously, thus increasing the risk of over-temperature phenomena in the remote controller.

[0132] In some embodiments, the temperature detection module 14 may include: a temperature measuring element. The temperature measuring element may be used to measure the current temperature of the light emitting module 13 and convert it into an electrical signal (which may be a temperature acquisition signal). In some embodiments, the temperature measuring element may be an element such as a thermistor, a thermocouple, or a temperature sensor.

[0133] In one embodiment, the temperature measuring element may be a negative temperature coefficient (NTC) thermistor or a positive temperature coefficient (PTC) thermistor. Among them, the resistance value of the NTC thermistor decreases as the temperature increases. This characteristic causes the current value of the electrical signal output by the temperature detection module 14 to increase when the temperature rises. The resistance value of the PTC thermistor increases as the temperature increases. This characteristic causes the current value of the electrical signal output by the temperature detection module 14 to decrease when the temperature rises.

[0134] It can be understood that when the temperature detection module 14 includes an NTC thermistor, the temperature detection module 14 may output a temperature acquisition signal with a first current value to the control module 12 after detecting the initial current temperature of the light emitting module 13; when the light emitting module 13 continues to work and heats up, the temperature detection module 14 may output a temperature acquisition signal with a second current value to the control module 12 after detecting the current temperature of the light emitting module 13. The first current value is less than the second current value. Similarly, when the temperature detection module 14 includes a PTC thermistor, the magnitude relationship between the first current value and the second current value is exactly opposite to the above situation.

[0135] In some embodiments, the temperature detection module 14 may further include: a temperature signal processing circuit. The temperature signal processing circuit is used to process the electrical signal output by the temperature measuring element (the electrical signal related to temperature) and output the processed electrical signal (which may be the above-mentioned temperature acquisition signal) to the control module 12. In one embodiment, the temperature signal processing circuit may adopt algorithms such as a calibration algorithm and a filtering algorithm to process the electrical signal output by the temperature measuring element to improve the temperature measurement accuracy of the temperature detection module 14.

[0136] In some embodiments, one end of the temperature signal processing circuit may be connected to the temperature measuring element, and the other end may be connected to the control module 12, so as to realize the connection between the temperature detection module 14 and the control module 12. In one embodiment, the temperature signal processing circuit and the temperature measuring element may be encapsulated together by a packaging material to ensure that the temperature detection module 14 is protected from external damage.

[0137] In one embodiment, to facilitate the temperature detection module 14 to detect the temperature of the light emission module 13, the temperature detection module 14 may be disposed adjacent to the light emission module 13. In one embodiment, the temperature detection module 14 may be in contact with the light emission module 13. For example, the temperature measuring element in the temperature detection module 14 may be in contact with the light emitting drive circuit in the light emission module 13.

[0138] In some embodiments, the control module 12 may include: a control circuit. The control circuit receives the temperature acquisition signal and outputs a working state indication signal to the light emission module.

[0139] It can be understood that the control circuit is configured to generate a working state indication signal after obtaining the current temperature of the light emission module 13 and send the working state indication signal to the light emission module 13.

[0140] In some embodiments, the control module 12 may further include: a communication interface. The communication interface is connected to the control circuit. The temperature detection module 14 outputs the temperature acquisition signal to the control circuit through the communication interface, and the control circuit outputs the working state indication signal to the light emission module 13 through the communication interface.

[0141] In the embodiment of the present application, according to the current temperature of the light emission module, the light emission module can operate in working states with different emission powers. Based on this, at least the light emission module can be switched to a working state with a lower emission power when the current temperature of the light emission module is too high, thereby reducing the heat generated by the light emission module and realizing the over-temperature protection function of the remote controller.

[0142] In some possible implementation manners, Figure 5 is a schematic circuit structure diagram of a remote controller provided by an embodiment of the present application. Refer to Figure 5 As shown, the light emission module 13 may include: a light emitter 131. The light emitter 131 may be at least partially exposed to the remote control housing 11. The working state indication signal includes a first working state indication signal and a second working state indication signal. Among them, the control module 12 may output the first working state indication signal to the light emitter 131. The light emitter 131 is driven by the first working state indication signal and can emit an optical signal with a first optical power, so that the light emission module 13 is in the first working state. The control module 12 may further output the second working state indication signal to the light emitter 131. The light emitter 131 is driven by the second working state indication signal and can emit an optical signal with a second optical power, so that the light emission module 13 is in the second working state.

[0143] Among them, optical power is a key parameter for measuring the intensity of optical signals in an optical communication system. The optical power of the optical signal emitted by the optical transmitter 131 can have a linear relationship with the current value input to the optical transmitter 131. In one embodiment, the first optical power is different from the second optical power.

[0144] In some embodiments, the signal values of the first working state indication signal and the second working state indication signal are different. In some embodiments, the signal types of the first working state indication signal and the second working state indication signal can be different. In some embodiments, the timing control of the first working state indication signal and the second working state indication signal can be different. For example, the first state signal can be a continuously enabled signal (such as long-period enabling), and the second state is an intermittent trigger signal (such as short-pulse triggering), reducing the average power consumption.

[0145] In some embodiments, the first optical power is greater than the second optical power. When the optical emission module 13 emits an optical signal with the first optical power by the optical transmitter 131, more heat is generated. When the optical emission module 13 emits an optical signal with the second optical power by the optical transmitter 131, less heat is generated.

[0146] In some embodiments, the optical transmitter 131 can be a light-emitting diode (LED). When the LED is driven by an electrical signal, it emits a visible light signal or an invisible light signal to a remote device. In one embodiment, the LED can be an infrared light-emitting diode that can emit an infrared light signal with a specific wavelength. In one embodiment, the LED can be a visible light-emitting diode that can emit a blue-green light signal with a specific wavelength to achieve high-precision underwater signal transmission.

[0147] In some embodiments, the optical emission module 13 can further include a laser diode driving circuit. The laser diode driving circuit can be connected to the LED and is used to adjust the driving current to change the output optical power of the laser by receiving the first or second working state indication signal. In one embodiment, the laser diode driving circuit can be disposed on a substrate or a circuit board.

[0148] In some embodiments, at least a part of the LED in the optical emission module 13 is exposed outside the remote control housing 11. The laser diode driving circuit in the optical emission module 13 is located inside the remote control housing 11. In one embodiment, the LED in the optical emission module 13 can be exposed outside the remote control housing 11 through a notch on the remote control housing 11.

[0149] In the embodiments of the present application, different working state indication signals are used to drive the optical transmitter to emit optical signals with different optical powers, so as to adjust the transmission power of the optical emission module. This can not only directly improve the penetration of the optical signals emitted by the optical transmitter, thereby enhancing the communication quality, performance and stability between the enhanced remote control and the pool robot, but also improve the hardware integration of the circuit structure between the control module and the optical emission module, and enhance the signal reliability.

[0150] In some possible implementation manners, Figure 6 is a schematic diagram of the circuit structure of a remote control provided by the embodiments of the present application. Refer to Figure 6 As shown, the remote control 10 may further include: a first power adjustment circuit 15. The first power adjustment circuit 15 may include a first branch 151 and a second branch 152 connected in parallel. The control module 12 is connected to the optical emission module 13 through the first branch 151, and the control module 12 is also connected to the optical emission module 13 through the second branch 152. The first branch 151 includes a first resistor R1, and the second branch includes a second resistor R2. The resistance values of the first resistor R1 and the second resistor R2 are different.

[0151] It can be understood that the first power adjustment circuit 15 may be connected between the output terminal a of the control module 12 and the input terminal c of the optical emission module 13. The first power adjustment circuit 15 may include a first branch 151 and a second branch 152 connected in parallel. Then, there may be one or two connection points between the first power adjustment circuit 15 and the control module 12. When there is one connection point, the first branch 151 and the second branch 152 may be commonly connected to one connection point; when there are two connection points, the first branch 151 and the second branch 152 are respectively connected to different connection points among the two connection points. Similarly, there may be one or two connection points between the first power adjustment circuit 15 and the control module 12.

[0152] In some embodiments, the input terminal b of the first power adjustment circuit 15 may be connected to the output terminal a of the control module 12, and the output terminal of the first power adjustment circuit 15 may be connected to the input terminal c of the optical emission module 13 through the first branch 151 and the second branch 152 connected in parallel.

[0153] In some embodiments, the working state indication signal is output to the optical emission module 13 via the first branch 151, and the optical emission module 13 operates at the first emission power; or, the working state indication signal is output to the optical emission module 13 via the second branch 152, and the optical emission module 13 operates at the second emission power.

[0154] It can be understood that the first branch 151 in the first power adjustment circuit 15 can adjust the power of the working status indication signal to obtain a first working status indication signal, and the optical emission module 13 is driven by the first working status indication signal to work at a first emission power. The second branch 152 in the first power adjustment circuit 15 can adjust the power of the working status indication signal to obtain a second working status indication signal, and the optical emission module 13 is driven by the second working status indication signal to work at a second emission power.

[0155] It can be understood that the resistance values of the first resistor R1 in the first branch 151 and the second resistor R2 in the second branch 152 are different. The first branch 151 can adjust the power of the working status indication signal through the first resistor R1 to obtain a first working status indication signal; the second branch 152 can adjust the power of the working status indication signal through the second resistor R2 to obtain a second working status indication signal.

[0156] In some embodiments, the specific structural composition of the first power adjustment circuit 15 can be set according to the usage requirements of the optical emission module 13, and no specific limitation is made thereto. In one embodiment, the optical emission module 13 may only include an LED, and the first power adjustment circuit 15 can also serve as the driving circuit of the LED. At this time, the first power adjustment circuit 15 can be a metal-oxide-semiconductor field-effect transistor (MOSFET) driving circuit or a constant current driving IC.

[0157] In the embodiments of the present application, the emission power of the optical emission module is adjusted by the first branch and the second branch which are connected in parallel and have different resistance values, so that the circuit structure has the characteristics of simple design and easy implementation.

[0158] In some embodiments, Figure 7 is a schematic diagram of the circuit structure of a remote control provided by the embodiments of the present application. Refer to Figure 7 As shown, the first power adjustment circuit 15 may further include a circuit body 153. The circuit body 153 has an input end d and an output end e. The input end d of the circuit body 153 is connected to the control module 12 as the input end b of the first power adjustment circuit 15; the output end e of the circuit body 153 is respectively connected to the first branch 151 and the second branch 152.

[0159] In some embodiments, the working state indication signal is output to the circuit main body 153, and the circuit main body 153 outputs a third working state indication signal to the first branch 151 and the second branch 152. The third working state indication signal is output to the optical emission module 13 via the first branch 151, and the optical emission module 13 operates at a first emission power; the third working state indication signal is output to the optical emission module 13 via the second branch 152, and the optical emission module 13 operates at a second emission power.

[0160] It can be understood that the circuit main body 153 is used to ensure that the working state indication signal sent by the control module 12 can be converted into a third working state indication signal suitable for the operation of the optical emission module 13. Among them, the third working state indication signal can be a pulse signal. The first branch 151 can adjust the power of the third working state indication signal through the first resistor R1 to obtain a first working state indication signal; the second branch 152 can adjust the power of the third working state indication signal through the second resistor R2 to obtain a second working state indication signal.

[0161] In some embodiments, the circuit main body 153 may include: a protection circuit. The overvoltage protection circuit is used to cope with the impacts generated in the circuit. For example, voltage impact, current impact, etc. Exemplarily, the protection circuit may include a protection resistor. Once the current exceeds a certain threshold, the protection mechanism can be automatically activated to increase the resistance value of the protection resistor, thereby effectively protecting the first power adjustment circuit 15 from damage.

[0162] In some embodiments, the circuit main body 153 may include: a filtering circuit. The filtering circuit is used to reduce the noise of the power supply and ensure the quality of the output electrical signal. Exemplarily, the filtering circuit may be formed by combining a capacitor and an inductor.

[0163] In some embodiments, the circuit main body 153 may include: a signal amplification or attenuation circuit. The signal amplification or attenuation circuit is used to amplify or attenuate the amplitude of the electrical signal input to the LED according to the working requirements of the LED in the optical emission module 13.

[0164] In the embodiments of the present application, the circuit main body is connected to the first branch and the second branch through the output end. Therefore, the emission power of the optical emission module can be adjusted by switching the signal path between the first branch and the second branch, which makes the power adjustment process more convenient and does not require complex modifications to the circuit.

[0165] In some embodiments, Figure 8 is a schematic diagram of the circuit structure of a remote control provided by the embodiments of the present application. Refer to Figure 6 and Figure 8As shown, the control module 12 may have a first pin a1 and a second pin a2. The first pin a1 may be connected to the first input terminal b1 of the first power adjustment circuit 15 as the output terminal a of the control module 12. At the same time, the first input terminal b1 of the first power adjustment circuit 15 is connected to the first end f1 of the first branch 151. The second pin a2 may be connected to the second input terminal b2 of the first power adjustment circuit 15 as the output terminal a of the control module 12. At the same time, the second input terminal b2 of the first power adjustment circuit 15 is connected to the first end f2 of the second branch 152. The first input terminal b1 and the second input terminal b2 are included in the input terminal b of the first power adjustment circuit 15.

[0166] It can be understood that the first end f1 of the first branch 151 can be connected to the first pin a1 of the control module 12, the second end of the first branch 151 can be connected to the input terminal c of the optical emission module 13, the first end f2 of the second branch 152 can be connected to the second pin a2 of the control module 12, and the second end of the second branch 152 can be connected to the input terminal c of the optical emission module 13. It can be seen that the first branch 151 and the second branch 152 are respectively controlled by different pins (the first pin a1 and the second pin a2) of the control module 12, and the first branch 151 and the second branch 152 are independent of each other and do not interfere with each other. In this way, the control module 12 can select to output the working state indication signal to the optical emission module 13 via the first branch 151, so that the optical emission module 13 works according to the first emission power, or can also select to output the working state indication signal to the optical emission module 13 via the second branch 152, so that the optical emission module 13 works according to the second emission power, thereby realizing more functional states and meeting different application requirements.

[0167] In some embodiments, when the first branch 151 and the second branch 152 are independently arranged between the control module 12 and the optical emission module 13, at least one of the first branch 151 and the second branch 152 may further include: as Figure 4 the circuit body 153 shown.

[0168] It can be understood that the functions and effects of the circuit body 153 can be referred to the descriptions in the above one or more embodiments, and will not be elaborated here.

[0169] In the embodiments of the present application, the emission power of the optical emission module can be adjusted by switching the signal path between the completely independent first branch and the second branch, which makes the power adjustment process more flexible and more independent, so as to meet different application requirements.

[0170] In some embodiments, Figure 9 is a schematic diagram of the circuit structure of a remote controller provided by the embodiments of the present application. Refer to Figure 9As shown, the remote controller 10 may further include: a second power adjustment circuit 16. The input terminal g of the second power adjustment circuit 16 is connected to the control module 12, and the output terminal h of the second power adjustment circuit 16 is connected to the light emission module 13.

[0171] In some embodiments, within each pulse period, the working state indication signal is output to the light emission module 13 via the second power adjustment circuit 16, and the output working state indication signal has a first duty cycle, and the light emission module 13 is driven by the output working state indication signal to work at a first emission power; or, within each pulse period, the working state indication signal is output to the light emission module 13 via the second power adjustment circuit 16, and the output working state indication signal has a second duty cycle, and the light emission module 13 works at a second emission power according to the output working state indication signal; wherein, the first duty cycle is different from the second duty cycle.

[0172] It can be understood that the second power adjustment circuit 16 can adjust the working state indication signal and then output it to the light emission module 13, and the output working state indication signal can drive the light emission module 13 to work.

[0173] Generally, the output working state indication signal can be a pulse signal. The pulse signal has a specific pulse period. The most common waveform of the pulse signal can be a square wave, which is characterized in that within one pulse period, the signal quickly switches from a high level to a low level and then switches back from the low level to the high level, forming a complete cycle. The duty cycle is an important parameter of the pulse signal. By adjusting the duty cycle of the pulse signal, the percentage of the duration when the pulse is at a higher voltage (or current) in the entire pulse period can be changed. In practical applications, when the pulse is at a higher voltage, the light emission module 13 can be in the emission state and has an emission duration; when the pulse is at a low voltage, the light emission module 13 is in the stop emission state. Therefore, by adjusting the duty cycle of the pulse signal, the emission duration of the light emission module 13 driven by the pulse signal can be changed, and further the emission power of the light emission module 13 can be changed.

[0174] It can be understood that the second power adjustment circuit 16 can adjust the duty cycle of the working state indication signal to obtain a first working state indication signal with a first duty cycle. The light emission module 13 is driven by the first working state indication signal with the first duty cycle and can work at a first emission power. At the same time, the first working state indication signal with the first duty cycle can drive the light emission module 13 to work with a first emission duration within each pulse period.

[0175] It can be understood that the second power adjustment circuit 16 can also adjust the duty cycle of the working state indication signal to obtain a second working state indication signal with a second duty cycle. The optical emission module 13 is driven by the second working state indication signal with the second duty cycle and can work at the second emission power. At the same time, the second working state indication signal with the second duty cycle can drive the optical emission module 13 to work for a second emission duration within each pulse period.

[0176] It can be understood that the first duty cycle is different from the second duty cycle, so that the first emission duration is different from the second emission duration, thereby realizing the control that the optical emission module 13 has different emission powers in different working states.

[0177] In some embodiments, the second power adjustment circuit 16 can also adjust the duty cycle of the working state indication signal, including: comparing the working state indication signal with a preset waveform to obtain the output working state indication signal.

[0178] It can be understood that the working state indication signal can be a pulse signal with a pulse period, that is, a pulse signal with a certain waveform (modulation wave). The second power adjustment circuit 16 can compare the sawtooth wave / triangle wave (carrier wave) with the waveform of the working state indication signal and determine the polarity of the output signal of the signal according to the comparison result, so as to obtain the output working state indication signal.

[0179] Exemplarily, when the working state indication signal is compared with the voltage value of the carrier signal, if the carrier signal is greater than the modulation wave signal, the output working state indication signal has a high voltage; otherwise, the output working state indication signal has a low voltage. In this way, the output working state indication signal can have a waveform that changes with the working state indication signal.

[0180] It can be understood that after receiving the working state indication signal, the second power adjustment circuit 16 can compare the working state indication signal with different carrier waves to obtain different adjusted working state indication signals (such as the first working state indication signal and the second working state indication signal).

[0181] In the embodiments of the present application, the second power adjustment circuit can enable the optical emission module to be driven by working state indication signals with different duty cycles, realize the control of the emission power of the optical emission module, and meet different application requirements.

[0182] In some possible implementation manners, in having Figures 2 to 9In the remote controller with the circuit structure shown, when the current temperature of the light emission module is greater than or equal to the first temperature threshold, the light emission module can be in the second working state. Among them, the emission power of the light emission module in the first working state is greater than the emission power of the light emission module in the second working state.

[0183] It can be understood that when the current temperature of the light emission module is greater than or equal to the first temperature threshold, the light emission module can be in the second working state with a lower emission power. In this way, the light emission module operates at a lower power, reducing heat release.

[0184] In some embodiments, the first temperature threshold can be set according to the usage requirements of the remote controller, and the embodiments of the present application do not limit this. In one example, the first temperature threshold is 75 °C.

[0185] In some embodiments, when the current temperature of the light emission module is greater than or equal to the first temperature threshold, the light emission module can switch from the second working state to the first working state.

[0186] It can be understood that when the current temperature of the light emission module is greater than or equal to the first temperature threshold, the control module can control the light emission module to switch from the first working state with a higher emission power to the second working state with a lower emission power. In this way, by switching the working state, the probability of the remote controller overheating is effectively reduced.

[0187] It can be understood that in the remote controller 10 with Figures 2 to 9 the circuit structure shown, when the current temperature of the light emission module is greater than or equal to the first temperature threshold, the light emission module is in the second working state. Based on this, the light emission module can also be switched from the first working state to the second working state.

[0188] Exemplarily, taking the remote controller 10 with Figure 4 the circuit structure shown as an example, the light emission module 13 can operate in the first working state. The temperature detection module 14 close to the light emission module 13 uses an NTC thermistor. When the temperature detection module 14 detects that the current temperature of the light emission module 13 is greater than or equal to the first temperature threshold, it outputs a temperature acquisition signal with a second current value to the control module 12. The control module 12 outputs a working state indication signal to the light emission module 13, and the light emission module 13 is driven by the working state indication signal to operate in the second working state. In this way, the light emission module 13 switches from the first working state to the second working state.

[0189] Exemplarily, taking the remote controller with Figure 6Taking the remote controller 10 with the shown circuit structure as an example, the optical emission module 13 can operate in the first working state. The control module 12 outputs a working state indication signal to the first power adjustment circuit 15. The working state indication signal is adjusted to a second working state indication signal via the second branch 152 in the first power adjustment circuit 15. The second working state indication signal is output to the optical emission module 13, and the optical emission module 13 is driven by the second working state indication signal to operate in the second working state. In this way, the optical emission module 13 switches from the first working state to the second working state for operation.

[0190] Exemplarily, taking the Figure 7 Taking the remote controller 10 with the shown circuit structure as an example, the optical emission module 13 can operate in the first working state. The control module 12 outputs a working state indication signal to the first power adjustment circuit 15. The working state indication signal is processed into a third working state indication signal via the circuit body 153 in the first power adjustment circuit 15. Subsequently, the third working state indication signal is adjusted to a second working state indication signal via the second branch 152 in the first power adjustment circuit 15. The second working state indication signal is output to the optical emission module 13, and the optical emission module 13 is driven by the second working state indication signal to operate in the second working state. In this way, the optical emission module 13 switches from the first working state to the second working state for operation.

[0191] Exemplarily, taking the Figure 8 Taking the remote controller 10 with the shown circuit structure as an example, the optical emission module 13 can operate in the first working state. The control module 12 outputs a working state indication signal to the first power adjustment circuit 15 through the second interface a2. It is adjusted to a second working state indication signal via the second branch 152 in the first power adjustment circuit 15. The second working state indication signal is output to the optical emission module 13, and the optical emission module 13 is driven by the second working state indication signal to operate in the second working state. In this way, the optical emission module 13 switches from the first working state to the second working state for operation.

[0192] Exemplarily, taking the Figure 9 Taking the remote controller 10 with the shown circuit structure as an example, the optical emission module 13 can operate in the first working state. The control module 12 outputs a working state indication signal to the second power adjustment circuit 16. The duty cycle of the working state indication signal is obtained via the second power adjustment circuit 16 to get a second working state indication signal with a second duty cycle. The second working state indication signal with the second duty cycle is output to the optical emission module 13, and the optical emission module 13 is driven by the second working state indication signal with the second duty cycle to operate in the second working state. In this way, the optical emission module 13 switches from the first working state to the second working state for operation.

[0193] In the embodiment of the present application, when the current temperature of the optical emission module is too high, the optical emission module can be switched to a working state with a lower emission power, thereby reducing the heat generated by the optical emission module and reducing the probability of the remote controller overheating, so that the remote controller has an over-temperature protection function.

[0194] In some possible implementation manners, in a remote controller having Figures 2 to 9 the circuit structure shown, the optical emission module works in the second working state for a third preset duration, and when the current temperature is greater than or equal to the first temperature threshold, the optical emission module stops working.

[0195] It can be understood that after the optical emission module is in the second working state with a lower emission power, the current temperature of the optical emission module can be detected by the temperature detection module. When the optical emission module works in the second working state for a third preset duration and the current temperature is still greater than or equal to the first temperature threshold, the optical emission module can stop working. In this way, the optical emission module stops generating heat, effectively reducing the probability of the remote controller overheating.

[0196] In some embodiments, a timer can be provided in the remote controller. The timer is used to accumulate the working duration of the optical emission module in the second working state. When the timer shows that the working duration has exceeded the third preset duration and the temperature detection module still detects that the current temperature of the optical emission module is greater than or equal to the first temperature threshold, the optical emission module stops working.

[0197] Exemplarily, taking the remote controller 10 having Figure 7 the circuit structure shown as an example, the optical emission module 13 can work in the second working state. The temperature detection module 14 uses an NTC thermistor. The control module 12 starts the timer, and when the timer shows that the working duration of the optical emission module in the second working state has exceeded the third preset duration and the temperature detection module outputs a temperature acquisition signal with a second current value, the control module 12 can stop outputting a working state indication signal to the second branch 152 of the first power adjustment circuit 15 through the second interface a2. In this way, the second branch 152 stops driving the optical emission module 13, and the optical emission module 13 stops working in the second working state.

[0198] In some embodiments, in the case where the optical emission module switches from the first working state to the second working state, if the optical emission module works in the second working state for a third preset duration and the temperature is greater than or equal to the first temperature threshold, the optical emission module stops working.

[0199] It can be understood that in the case where the optical emission module switches from the first working state to the second working state, if the optical emission module operates in the second working state with a relatively low emission power for a third preset duration and the temperature is still greater than or equal to the first temperature threshold, the optical emission module stops working. In this way, the remote control continuously detects the temperature of the optical emission module to implement the overheat protection function.

[0200] In the embodiments of the present application, when the optical emission module switches to a working state with a relatively low emission power and there is still a large amount of heat accumulated in the remote control, it can stop working and no longer generate heat, thereby reducing the probability of the remote control overheating and implementing the over-temperature protection function for the remote control.

[0201] In some possible implementation manners, in a remote control having Figures 2 to 9 the shown circuit structure, when the current temperature of the optical emission module is less than the first temperature threshold, the optical emission module is in the first working state.

[0202] It can be understood that when the current temperature of the optical emission module is less than the first temperature threshold, the optical emission module can be in the first working state with a relatively high emission power. In this way, the working performance of the optical emission module is improved.

[0203] In some embodiments, when the current temperature of the optical emission module is less than the second temperature threshold, the optical emission module can switch from the second working state to the first working state. Wherein, the second temperature threshold is less than or equal to the first temperature threshold.

[0204] It can be understood that when the current temperature is less than the second temperature threshold, the optical emission module can switch from the second working state with a relatively low emission power to the first working state with a relatively high emission power. In this way, high-power operation is achieved. Although it will generate a certain amount of heat, it can improve the quality of the optical signal emitted by the optical emission module, optimize the performance of the optical emission module, and meet specific application requirements.

[0205] In some embodiments, the second temperature threshold can be set according to the usage requirements of the remote control, and the embodiments of the present application do not limit this. In one example, the second temperature threshold is 55 °C.

[0206] It can be understood that the process of the optical emission module switching from the second working state to the first working state can refer to the process of the optical emission module switching from the first working state to the second working state. For the sake of simplicity of the specification, it will not be elaborated here.

[0207] In some embodiments, the light emitting module can switch from the first working state to the second working state. When the light emitting module switches from the first working state to the second working state, if the temperature of the light emitting module after a third preset duration is greater than or equal to the first temperature threshold, the light emitting module stops working. The light emitting module can switch from the second working state to the first working state.

[0208] It can be understood that through the combination of the above multiple working state switching methods, the remote control can meet more application requirements. In one example, the usage process of the remote control includes: starting the light emitting module in the remote control to work at a power of 6W. After working for a period of time, the NTC thermistor in the temperature detection module detects that the LED in the light emitting module reaches 75 ± 1 °C, the indicator light in the indicator module flashes quickly, the remote control enters the sleep state, and the LED stops emitting optical signals. When the temperature drops to 55 ± 1 °C, the remote control can be turned on, and the emitting module works at a power of 4W when it is turned on. In one example, the usage process of the remote control includes: starting the light emitting module in the remote control to work at a power of 6W. After working for a period of time, the NTC thermistor in the temperature detection module detects that the LED in the light emitting module reaches 75 ± 1 °C, and then directly switches to the 4W power mode. When the temperature drops to 55 ± 1 °C, the 6W power mode is restored.

[0209] In the embodiments of the present application, when the current temperature of the light emitting module is relatively low, the light emitting module can be switched to a working state with a higher emission power, so as to increase the intensity of the optical signal emitted by the light emitting module, improve the quality of the optical signal emitted by the light emitting module, ensure the optical signal transmission effect, and meet the user's usage requirements for the remote control.

[0210] In some possible implementation manners, in a remote control having Figures 2 to 9 the shown circuit structure, when the current temperature of the light emitting module is greater than or equal to the first temperature threshold, the light emitting module can also stop working. If the light emitting module stops working for a fourth preset duration and the temperature is less than the third temperature threshold, the light emitting module can be in the second working state; wherein, the third temperature threshold is less than or equal to the first temperature threshold.

[0211] It can be understood that when the optical emission module is in the first working state with a relatively high emission power and the temperature detection module detects that the current temperature of the optical emission module is greater than or equal to the first temperature threshold, the optical emission module can stop working. When the optical emission module has been in the stopped working state for a fourth preset duration and the current temperature is still less than the third temperature threshold, the optical emission module can start working in the second working state with a relatively low emission power. In this way, on the one hand, the waiting time of the user can be reduced and the user experience can be improved. On the other hand, the optical emission module transitions through the working state with a low emission power. Compared with directly starting the emission state working mode, it can also avoid the over-temperature phenomenon of the remote control again.

[0212] In some embodiments, a timer can be set in the remote control. The timer is used to accumulate the stop duration when the optical emission module stops working. After the timer shows that the stop duration has exceeded the fourth preset duration and the temperature detection module detects that the current temperature of the optical emission module is less than the third temperature threshold, the optical emission module can work in the working state with a low emission power.

[0213] In one embodiment, the third temperature threshold can be set according to actual needs, and the embodiments of the present application do not limit this. In one embodiment, the third temperature threshold can be the same as the second temperature threshold; or, the third temperature threshold can be different from the second temperature threshold.

[0214] In one embodiment, the fourth preset duration can be set according to actual needs, and the embodiments of the present application do not limit this. In one embodiment, the fourth preset duration can be the same as the third preset duration; or, the fourth preset duration can be different from the third preset duration.

[0215] In the embodiments of the present application, when the optical emission module overheats in the first working state with a relatively high emission power and triggers the optical emission module to stop working, if the optical emission module can cool down to the preset temperature within the preset duration, the optical emission module can start working in the second working state with a relatively low emission power, so that the user waiting time can be reduced.

[0216] In some possible implementation manners, Figure 10 is a schematic circuit structure diagram of a remote control provided by an embodiment of the present application. Refer to Figure 10 As shown, the remote control 10 may further include at least one of a prompt module 17 and a heat dissipation module 18.

[0217] In some embodiments, the prompt module 17 can be partially exposed outside the remote control housing 11, and the prompt module 17 can be connected to the control module 12. The prompt module 17 can be used to output a prompt message when the current temperature of the optical emission module 13 is greater than or equal to the first temperature threshold.

[0218] Among them, the prompt information includes light effect prompt information, vibration prompt information or voice prompt information.

[0219] It can be understood that the prompt module 17 can be partially exposed outside the remote control housing 11. When the control module 12 determines that the current temperature of the light emitting module 13 is greater than or equal to the first temperature threshold according to the first signal sent by the temperature detection module 14, the control module 12 can send a prompt signal to the prompt module 17. Here, the prompt signal is used to instruct the prompt module 17 to output prompt information. After receiving the prompt signal, the prompt module 17 can output light effect prompt information, vibration prompt information or voice prompt information.

[0220] In one embodiment, the prompt module 17 may include: one or more prompt lights. The prompt lights are used to output light effect prompt information. The prompt module 17 outputting light effect prompt information may include: the prompt module 17 turning on the prompt lights, the prompt module 17 changing the color of the prompt lights, the prompt module 17 changing the flashing frequency of the prompt lights, etc.

[0221] In one embodiment, the prompt module 17 may include: a vibration component. The vibration component is used to output vibration prompt information. The prompt module 17 outputting vibration prompt information may include: starting the vibration of the vibration component.

[0222] In one embodiment, the prompt module 17 may include: a speaker. The speaker is used to output voice prompt information. The prompt module 17 outputting voice prompt information may include: the prompt module 17 outputting voice through the speaker.

[0223] It can be seen that the prompt module 17 plays an important role in temperature monitoring and prompting in the remote control, so as to meet the user's usage requirements.

[0224] In some embodiments, the heat dissipation module 18 may be located inside the remote control housing 11 and be connected to the light emitting module 13 and the remote control housing 11. The heat dissipation module 18 is used to dissipate heat from the light emitting module 13.

[0225] It can be understood that the heat dissipation module 18 may adopt various heat dissipation technologies, such as heat sinks, heat dissipation structures containing heat dissipation materials, etc. By connecting the heat dissipation module 18 to the light emitting module 13 and the remote control housing 11, the heat of the light emitting module 13 can be promoted to transfer to the remote control housing 11, thereby achieving a heat dissipation effect, prolonging the service life of the light emitting module 13, and improving the overall performance and reliability of the remote control device.

[0226] In some embodiments, the heat dissipation module 18 may include a heat dissipation structure formed of a thermally conductive insulating silicone material, such as thermal grease. It can be understood that the thermal grease can be in contact with the surface of the light emitting module 13 on one side and the inner surface of the remote control housing 11 on the other side. The thermal grease can fill the air gap between the light emitting module 13 and the remote control housing 11, replacing the air with the thermally conductive grease with high thermal conductivity, thereby improving the heat dissipation efficiency of the light emitting module 13.

[0227] In some embodiments, still referring to Figure 10 , the remote control 10 may further include at least one of a battery circuit 19, a protection circuit 20, a charging integrated circuit 21, a power management circuit 22, an interface circuit 23, and a key circuit 24.

[0228] Among them, the battery circuit 19, the protection circuit 20, the charging integrated circuit 21, the power management circuit 22, the interface circuit 23, and the key circuit 24 are all connected to the control module 12 and are jointly used to ensure the normal use of the remote control 10.

[0229] In one embodiment, the battery circuit 19 is used to provide a stable power supply for the remote control 10 to ensure that the remote control 10 can work properly. The protection circuit 20 is used to protect the remote control 10 from abnormal conditions such as overcurrent, overvoltage, and overheating, improving the safety and stability of the remote control 10. The charging integrated circuit 21 is used to manage the charging process of the remote control 10 to ensure that the battery can be charged safely and quickly. The power management circuit 22 is used for power distribution and energy efficiency optimization to ensure that each circuit component in the remote control 10 can obtain a stable power supply. The interface circuit 23 provides a connection interface with external devices or chargers to facilitate data transmission and charging of the remote control 10. The key circuit 24 is used to detect the user's key operation to ensure the normal use of the remote control 10.

[0230] In the embodiments of the present application, a prompt module can be added to the remote control to output prompt information to help the user timely understand and respond to the temperature condition of the light emitting module. A heat dissipation module can be added inside the remote control for heat dissipation, thereby improving the overall performance and reliability of the remote control device.

[0231] It should be noted that the above only shows the specific circuit structure (such as the first power adjustment circuit, the second power adjustment circuit, etc.) in the remote control provided in the second aspect. Through this circuit structure, the light emitting module can work in the first working state or the second state in response to the working state indication signal sent by the control module. Those skilled in the art should understand that this circuit structure can also be set in the remote control provided in the first aspect, so that the light emitting module can also work in the first working state or the second state in response to the working state indication signal sent by the control module.

[0232] In a third aspect, an embodiment of the present application provides a pool robot.

[0233] In some embodiments, the pool robot may include: a light receiving module. The light receiving module is configured to receive a target signal so that the pool robot performs an action corresponding to the target signal. Wherein, the target signal is a signal emitted by the light emitting module in the remote controller according to any one of the first aspect and the second aspect. The action corresponding to the target signal can be set according to actual needs, and the embodiments of the present application do not limit this.

[0234] It can be understood that the light emitting module in the remote controller can emit an optical signal, which has the ability to transmit across media. The light receiving module of the pool robot can receive the optical signal and determine the optical signal as the target signal. In response to the target signal, the pool robot can perform the action corresponding to the target signal.

[0235] Among them, the specific structure of the remote controller can refer to the remote controller described in any one of the embodiments of Figures 2 to 9 For the sake of simplicity of the specification, it will not be described in detail here. It can be understood that the light emitting module of the remote controller has a first working state and a second working state; the emission power of the light emitting module in the first working state is different from the emission power of the light emitting module in the second working state. In this way, the remote controller can emit two optical signals corresponding to different emission powers, and the light receiving module of the pool robot can receive the two optical signals corresponding to different emission powers.

[0236] In some embodiments, the light emitting module may include: a light sensor. The light sensor is configured to capture the target signal. The light sensor may be a PIN photodiode (PIN Diode) or an avalanche photodiode (APD).

[0237] In the embodiments of the present application, there is a cross-media communication capability between the pool robot and the remote controller, so that the pool robot can execute corresponding actions under the control of the remote controller to meet the user's usage requirements. At the same time, the light emission module in the remote controller connected to the pool robot can work in working states with different transmission powers. Based on this, on the one hand, since the light emission module has two transmission powers, compared with the prior art where the light emission module only has one transmission power, the flexibility and adaptability of the remote controller are improved; on the other hand, since the light emission module has two transmission powers, the optical signals emitted by the light emission module at the two luminous powers can adapt to two media with different transmission characteristics, enabling the remote controller to flexibly cope with the differential transmission requirements of optical signals in the two media. On the other hand, the light emission module can switch between a higher transmission power and a lower transmission power, realizing intelligent power management and achieving the comprehensive optimization of the energy consumption, performance, and reliability of the remote controller, especially suitable for the scenario where the remote controller collaborates with the pool robot to jointly cope with complex light and distance changes.

[0238] Those skilled in the art can understand that the magnitudes of the sequence numbers of the steps in the above embodiments do not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation to the implementation process of the embodiments of the present application.

[0239] The above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application, and should all be included in the protection scope of the present application.
