Description

Technical Field

[0001] This invention relates to the field of law enforcement recorders, and more particularly to a law enforcement recorder with adaptive parameter adjustment and a control method thereof. Background Technology

[0002] A law enforcement recorder, also known as a police law enforcement recorder or on-site law enforcement recorder, integrates digital video recording, digital photography, and a walkie-talkie. It can digitally record dynamic and static scenes during law enforcement, facilitating its use by police officers in various environments. Law enforcement recorders are often used in conjunction with walkie-talkies, providing them with a microphone and speaker. However, during law enforcement operations, especially in outdoor settings, certain special scenarios may arise, such as locations with dense fog or high humidity. Fog can easily accumulate at the lens, causing blurry footage and making the captured images unclear, which is detrimental to the collection of on-site video data. Summary of the Invention

[0003] This invention overcomes the shortcomings of the prior art and provides a law enforcement recorder and control method with adaptive parameter adjustment.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0005] The first aspect of this invention provides a law enforcement recorder with adaptive parameter adjustment, specifically comprising:

[0006] The recorder itself and the control chip,

[0007] At least one camera lens is mounted on the recorder body.

[0008] Several fog sensors are arranged in a ring around the camera lens. The amount of fog on the camera lens is identified by the fog sensors to obtain the amount of fog on the camera lens.

[0009] A ring-shaped defogging mechanism is provided on the periphery of the camera lens. When the amount of fog on the camera lens is greater than a predetermined amount of fog, the ring-shaped defogging mechanism is used to defog the camera lens.

[0010] In this law enforcement recorder, the annular defogging mechanism includes a first annular block, on the inner side of which a bearing is mounted, and the outer ring of the bearing is connected to a second annular block, causing the second annular block to rotate.

[0011] In this law enforcement recorder, the second annular block has a plurality of through holes arranged in a circular array on its circumference, and the through holes cover the camera lens and blow air along the outside of the camera lens toward the center of the camera lens.

[0012] In this law enforcement recorder, several rods arranged in a circular array are also installed on the circumference of the second annular block. The upper and lower end faces of the rods are square or rectangular in shape, and the second annular block rotates by the input of gas interacting with the rods.

[0013] In this law enforcement recorder, ventilation holes are provided on both sides of the first annular block, and a ventilation rod is connected to the ventilation hole through a thread. The ventilation rod is connected to a gas delivery box.

[0014] In this law enforcement recorder, the gas delivery box has a hollow interior and at least one delivery cylinder is provided on the gas delivery box, and a blower is provided on the delivery cylinder.

[0015] In this law enforcement recorder, a sealing block is also provided on the first annular block, and the sealing block is connected to the first annular block and the second annular block respectively.

[0016] Another aspect of the present invention provides a control method for a law enforcement recorder with adaptive parameter adjustment, applicable to any of the law enforcement recorders with adaptive parameter adjustment described in the present invention, comprising the following steps:

[0017] The amount of fog on the camera lens is identified by a fog sensor, the amount of fog generated on the camera lens within a unit time is obtained, a fog amount threshold is set, and it is determined whether the amount of fog generated on the camera lens within the unit time is greater than the fog amount threshold.

[0018] When the amount of fog generated on the camera lens within a unit time exceeds the fog amount threshold, the amount of fog cleared by the blower within a unit time under various operating parameters is obtained, a database is constructed, and the amount of fog cleared by the blower within a unit time under various operating parameters is input into the database for storage.

[0019] The amount of fog generated on the camera lens within the unit time is input into the database for data acquisition. The working parameters of the blower are obtained when the amount of fog cleared within the unit time is greater than the amount of fog generated on the camera lens within the unit time.

[0020] The blower is controlled by a control chip based on the operating parameters of the blower corresponding to the amount of fog cleared within a unit time being greater than the amount of fog generated on the camera lens within a unit time.

[0021] The control method for law enforcement recorders with adaptive parameter adjustment also includes:

[0022] The system acquires image data information collected by law enforcement recorders within a preset time period, and identifies the image data information collected by law enforcement recorders within the preset time period through a control chip to acquire image clarity data corresponding to each image data information collected by law enforcement recorders within the preset time period.

[0023] The average image clarity data corresponding to the image data within the preset time is calculated based on the image clarity data corresponding to the image data information collected by each law enforcement recorder within the preset time, and an average image clarity data threshold is set.

[0024] Determine whether the average image sharpness data corresponding to the image data within the preset time is greater than the average image sharpness data threshold. If it is greater, there is no need to adjust the working parameters of the law enforcement recorder when acquiring images.

[0025] If the average image clarity data corresponding to the image data within the preset time is greater than the average image clarity data threshold, then the optimal working parameters for image acquisition under the current working environment are obtained, and the law enforcement recorder is adaptively controlled according to the optimal working parameters for image acquisition under the current working environment.

[0026] In the control method for a law enforcement recorder with adaptive parameter adjustment, the step of obtaining the optimal operating parameters for image acquisition under the current working environment and adaptively controlling the law enforcement recorder based on the optimal operating parameters for image acquisition under the current working environment specifically includes:

[0027] By using big data retrieval, image clarity data information of the law enforcement recorder under different environmental parameters and various operating parameters is obtained, and the image clarity data information of the law enforcement recorder under different environmental parameters and various operating parameters is input into the database for storage;

[0028] The system acquires the current working environment data information of the law enforcement recorder and inputs the current working environment data information of the law enforcement recorder into the database for data acquisition, and acquires the image clarity data information corresponding to each working parameter under the current working environment data information of the law enforcement recorder;

[0029] By sorting the image clarity data information corresponding to each working parameter under the current working environment data information of the law enforcement recorder from largest to smallest, the working parameter corresponding to the largest image clarity data information is obtained and used as the optimal working parameter when acquiring images under the current working environment.

[0030] The law enforcement recorder is adaptively controlled based on the optimal operating parameters for image acquisition under the current working environment.

[0031] This invention addresses the shortcomings of the prior art and has the following beneficial effects:

[0032] This invention, by incorporating a ring-shaped defogging mechanism into the camera lens of a law enforcement recorder, enables law enforcement officers to obtain clearer images or video data in areas with high humidity, heavy fog, or severe smog. The mechanism adaptively adjusts its operating parameters based on data from a fog sensor, saving energy while automatically removing fog and dirt from the camera lens, resulting in clearer video or image data acquired by the law enforcement recorder during law enforcement operations.

[0044] To facilitate understanding of the present invention, a more complete description will be given below with reference to the accompanying drawings. Preferred embodiments of the invention are shown in the drawings. However, the invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a thorough and complete understanding of the disclosure of the invention.

[0045] Example 1

[0046] like Figures 1 to 3As shown, the first aspect of the present invention provides a law enforcement recorder with adaptive parameter adjustment, which specifically includes the following components: a recorder body 1 and a control chip, a plurality of camera lenses 2 mounted on the recorder body 1, and a plurality of fog sensors or temperature sensors, or a combination of fog sensors and temperature sensors, arranged in a ring around the camera lenses 2.

[0047] It should be noted that when the sensor is a fog sensor, the amount of fog on the camera lens 2 is identified by the fog sensor to obtain the amount of fog on the camera lens. Moreover, by setting an annular defogging mechanism 3 on the periphery of the camera lens 2, when the amount of fog on the camera lens 2 is greater than the predetermined amount of fog, the annular defogging mechanism 3 defogs the camera lens.

[0048] It should be noted that in this embodiment, the recorder should also include components such as power supply, display, and light source, as well as batteries such as storage batteries and lithium batteries. Since these types of components are conventional components in the field, they are not mentioned or involved in detail in this embodiment.

[0049] like Figures 4 to 5 As shown, in this law enforcement recorder, the annular defogging mechanism 3 includes a first annular block 301, a bearing 302 is installed on the inner side of the first annular block 301, and the outer ring of the bearing 302 is connected to the second annular block 303, so that the second annular block 303 can rotate.

[0050] like Figures 1 to 5 As shown, in this law enforcement recorder, the second annular block 303 has a plurality of through holes 3031 arranged in a circular array on its circumference, and the through holes 3031 surround the camera lens 302 and blow along the outside of the camera lens 302 toward the center of the camera lens 2.

[0051] It should be noted that in this embodiment, when the amount of fog is greater than the preset amount of fog, the gas can flow into the through hole of the second annular block 303. Since the through hole 3031 is located outside the camera lens 302 and blows along the outside of the camera lens 302 towards the center of the camera lens 2, the fog can be cleared from multiple directions and concentrated at the center. This is equivalent to the gas gathering at the center, thereby achieving a better defogging effect.

[0052] In this law enforcement recorder, ventilation holes 3011 are provided on both sides of the first annular block 301, and the ventilation holes 3011 are connected to the ventilation rod 305 by threads. The ventilation rod 305 is connected to the gas delivery box 306.

[0053] In this law enforcement recorder, several rods 304 arranged in a circular array are also installed on the circumference of the second annular block 303. The upper and lower end faces of the rods 304 are square or rectangular in shape, and gas is input to interact with the rods 304, causing the second annular block 303 to rotate.

[0054] It should be noted that after the gas enters the gas delivery box 306, it is then fed into the vent rod 305, allowing the gas to flow from the vent rod 305 into the vent hole 3011. Figure 5 As shown, two vents are provided, and the two vents are designed to be 180 degrees apart. When gas is introduced into the vent rod 305, the gas reacts with the upper or lower end face of the rod 304 (e.g., Figure 5 As shown, the right side is the lower end face and the left side is the upper end face. This action causes the second annular block 303 to rotate, which allows for 360-degree rotation of the lens to remove fog, resulting in a better defogging effect.

[0055] In this law enforcement recorder, the gas delivery box 306 has a hollow interior and at least one delivery cylinder 307 is provided on the gas delivery box 306, and a blower 308 is provided on the delivery cylinder 307.

[0056] In this law enforcement recorder, a sealing block 309 is also provided on the first annular block 301, and the sealing block 309 is connected to the first annular block 301 and the second annular block 303 respectively.

[0057] It should be noted that the rods and sealing blocks are made of flexible materials, such as rubber. When it is necessary to clean the dust or water inside, remove the sealing block, clean the dust or water inside, and then reinstall it.

[0058] Example 2,

[0059] It should be noted that when the sensor is a temperature sensor, the working temperature value on the camera lens 2 is identified by the temperature sensor to obtain the temperature value on the camera lens. Moreover, since an annular defogging mechanism 3 is provided on the periphery of the camera lens 2, when the temperature value on the camera lens 2 is greater than the predetermined temperature value, the annular defogging mechanism 3 performs ventilation and cooling treatment on the camera lens.

[0060] It should be noted that, such as Figures 4 to 5 As shown, in this law enforcement recorder, the annular defogging mechanism 3 includes a first annular block 301, a bearing 302 is installed on the inner side of the first annular block 301, and the outer ring of the bearing 302 is connected to the second annular block 303, so that the second annular block 303 can rotate.

[0061] like Figures 1 to 5As shown, in this law enforcement recorder, the second annular block 303 has a plurality of through holes 3031 arranged in a circular array on its circumference, and the through holes 3031 surround the camera lens 302 and blow along the outside of the camera lens 302 toward the center of the camera lens 2.

[0062] It should be noted that in this embodiment, when the temperature value is greater than the preset temperature value, the gas can flow into the through hole of the second annular block 303. Since the through hole 3031 is located outside the camera lens 302 and blows along the outside of the camera lens 302 towards the center of the camera lens 2, cooling can be achieved from multiple directions and can be concentrated at the center. It is equivalent to the gas being gathered at the center, thereby achieving a better cooling effect.

[0063] In this law enforcement recorder, ventilation holes 3011 are provided on both sides of the first annular block 301, and the ventilation holes 3011 are connected to the ventilation rod 305 by threads. The ventilation rod 305 is connected to the gas delivery box 306.

[0064] In this law enforcement recorder, several rods 304 arranged in a circular array are also installed on the circumference of the second annular block 303. The upper and lower end faces of the rods 304 are square or rectangular in shape, and gas is input to interact with the rods 304, causing the second annular block 303 to rotate.

[0065] It should be noted that after the gas enters the gas delivery box 306, it is then fed into the vent rod 305, allowing the gas to flow from the vent rod 305 into the vent hole 3011. Figure 5 As shown, two vents are provided, and the two vents are designed to be 180 degrees apart. When gas is introduced into the vent rod 305, the gas reacts with the upper or lower end face of the rod 304 (e.g., Figure 5 As shown, the right side is the lower end face and the left side is the upper end face. This action causes the second annular block 303 to rotate. After it rotates, the air circulation speed is increased, which can rotate the lens 360 degrees to cool it down, resulting in a better cooling effect.

[0066] In this law enforcement recorder, the gas delivery box 306 has a hollow interior and at least one delivery cylinder 307 is provided on the gas delivery box 306, and a blower 308 is provided on the delivery cylinder 307.

[0067] It should be noted that two blowers 308 are shown in the figure. Those skilled in the art can increase or decrease the number of blowers 308 according to actual needs, and are not limited to the number shown in the figure.

[0068] Example 3,

[0069] It should be noted that when the sensor is a temperature sensor and a fog sensor, the temperature sensor identifies the working temperature value and fog volume on the camera lens 2 to obtain the temperature value and fog volume on the camera lens. Moreover, by setting an annular defogging mechanism 3 on the periphery of the camera lens 2, when the temperature value on the camera lens 2 is greater than a predetermined temperature value and when the fog volume is greater than a predetermined fog volume, the annular defogging mechanism 3 performs ventilation cooling and defogging treatment on the camera lens.

[0070] It should be noted that, such as Figures 4 to 5 As shown, in this law enforcement recorder, the annular defogging mechanism 3 includes a first annular block 301, a bearing 302 is installed on the inner side of the first annular block 301, and the outer ring of the bearing 302 is connected to the second annular block 303, so that the second annular block 303 can rotate.

[0071] like Figures 1 to 5 As shown, in this law enforcement recorder, the second annular block 303 has a plurality of through holes 3031 arranged in a circular array on its circumference, and the through holes 3031 surround the camera lens 302 and blow along the outside of the camera lens 302 toward the center of the camera lens 2.

[0072] It should be noted that in this embodiment, when the temperature value is greater than the preset temperature value, the gas can flow into the through hole of the second annular block 303. Since the through hole 3031 is located outside the camera lens 302 and blows along the outside of the camera lens 302 towards the center of the camera lens 2, cooling and defogging can be performed from multiple directions, and the gas can be concentrated at the center, which is equivalent to the gas being gathered at the center, thereby achieving a better cooling and defogging effect.

[0073] In this law enforcement recorder, ventilation holes 3011 are provided on both sides of the first annular block 301, and the ventilation holes 3011 are connected to the ventilation rod 305 by threads. The ventilation rod 305 is connected to the gas delivery box 306.

[0074] In this law enforcement recorder, several rods 304 arranged in a circular array are also installed on the circumference of the second annular block 303. The upper and lower end faces of the rods 304 are square or rectangular in shape, and gas is input to interact with the rods 304, causing the second annular block 303 to rotate.

[0075] It should be noted that after the gas enters the gas delivery box 306, it is then fed into the vent rod 305, allowing the gas to flow from the vent rod 305 into the vent hole 3011. Figure 5As shown, two vents are provided, and the two vents are designed to be 180 degrees apart. When gas is introduced into the vent rod 305, the gas reacts with the upper or lower end face of the rod 304 (e.g., Figure 5 As shown, the right side is the lower end face and the left side is the upper end face. This action causes the second annular block 303 to rotate. After it rotates, the air circulation speed is increased, which can rotate the lens 360 degrees to cool it down and remove fog, resulting in better cooling and defogging effects.

[0076] In this law enforcement recorder, the gas delivery box 306 has a hollow interior and at least one delivery cylinder 307 is provided on the gas delivery box 306, and a blower 308 is provided on the delivery cylinder 307.

[0077] Another aspect of the present invention provides a control method for a law enforcement recorder with adaptive parameter adjustment, applicable to any law enforcement recorder with adaptive parameter adjustment, comprising the following steps:

[0078] The amount of fog on the camera lens is identified by a fog sensor, the amount of fog generated on the camera lens within a unit of time is obtained, and a fog amount threshold is set to determine whether the amount of fog generated on the camera lens within a unit of time is greater than the fog amount threshold.

[0079] When the amount of fog generated on the camera lens within a unit time exceeds the fog amount threshold, the amount of fog cleared by the blower within a unit time under various operating parameters is obtained, a database is constructed, and the amount of fog cleared by the blower within a unit time under various operating parameters is input into the database for storage.

[0080] The amount of fog generated on the camera lens within a unit time is input into the database for data acquisition. The working parameters of the blower are obtained when the amount of fog cleared within a unit time is greater than the amount of fog generated on the camera lens within a unit time.

[0081] The operating parameters of the blower are controlled by a control chip based on the amount of fog cleared per unit time being greater than the amount of fog generated on the camera lens per unit time.

[0082] It should be noted that the operating parameters of the blower include data such as speed, voltage, current, and power. Since different speed settings and operating power of the blower will result in different air volumes, different air volumes can be set when the amount of fog generated on the camera lens per unit time varies. This allows for dynamic adjustment of the blower's operating parameters, saving energy while achieving better defogging results.

[0083] The control method for law enforcement recorders with adaptive parameter adjustment also includes:

[0084] The system acquires image data information collected by law enforcement recorders within a preset time period, and identifies the image data information collected by law enforcement recorders within the preset time period through a control chip, thereby acquiring the image clarity data corresponding to each image data information collected by law enforcement recorders within the preset time period.

[0085] The average image clarity data corresponding to the image data within the preset time is calculated based on the image clarity data corresponding to the image data information collected by each law enforcement recorder within the preset time, and the average image clarity data threshold is set.

[0086] Determine whether the average image sharpness data corresponding to the image data within the preset time is greater than the average image sharpness data threshold. If it is greater, there is no need to adjust the working parameters of the law enforcement recorder when acquiring images.

[0087] If the average image clarity data corresponding to the image data within the preset time is greater than the average image clarity data threshold, then the optimal working parameters for image acquisition under the current working environment are obtained, and the law enforcement recorder is adaptively controlled according to the optimal working parameters for image acquisition under the current working environment.

[0088] It should be noted that the optimal operating parameters for image acquisition include data such as contrast, exposure, and brightness. Due to the influence of weather and environmental conditions at law enforcement sites, the captured images or videos may be unclear. By embedding a program related to this method into the control chip, the law enforcement recorder can adaptively control itself based on the optimal operating parameters for image acquisition under the current working environment, including data such as temperature, humidity, visibility, ambient brightness, and light intensity.

[0089] In the control method for a law enforcement recorder with adaptive parameter adjustment, the steps of obtaining the optimal operating parameters for image acquisition under the current working environment and adaptively controlling the law enforcement recorder based on these optimal operating parameters specifically include:

[0090] Through big data retrieval, image clarity data of law enforcement recorders under different environmental parameters and various operating parameters is obtained, and this data is then input into the database for storage.

[0091] The system acquires the current working environment data of the law enforcement recorder and inputs it into the database for data acquisition. It then acquires the image clarity data corresponding to each working parameter under the current working environment data of the law enforcement recorder.

[0092] By sorting the image clarity data corresponding to each working parameter under the current working environment data information of the law enforcement recorder from largest to smallest, the working parameter corresponding to the largest image clarity data information is obtained and used as the optimal working parameter when acquiring images under the current working environment.

[0093] The law enforcement recorder is adaptively controlled based on the optimal operating parameters for image acquisition under the current working environment.

[0094] It should be noted that the working environment parameters include data such as temperature, humidity, visibility, ambient brightness, and light intensity. By embedding a program related to this method into the control chip, the law enforcement recorder can adaptively control itself based on the optimal working parameters for image acquisition under the current working environment, enabling the law enforcement recorder to acquire better video data according to changes in the environment.

[0095] On the other hand, this embodiment may also include: acquiring characteristic data of the air supply performance change of the blower, constructing an air supply performance prediction model based on a neural network, inputting the characteristic data of the air supply performance change of the blower into the air supply performance prediction model for training, and obtaining the trained air supply performance prediction model; acquiring characteristic data of the air supply performance change of the blower within a preset time period, inputting the characteristic data of the air supply performance change of the blower within the preset time period into the trained air supply performance prediction model for prediction, acquiring the air supply performance characteristic data of the current timestamp, and adjusting the operating parameters of the blower corresponding to the amount of fog cleared within a unit time period being greater than the amount of fog generated on the camera lens within a unit time period based on the air supply performance characteristic data of the current timestamp.

[0096] It should be noted that, in reality, after a certain number of years of use, the performance of the blower will degrade, such as the decrease in the air volume generated per unit time at the rated power. This method can optimize the operating parameters of the blower, thereby further improving the defogging effect of the camera lens.

[0097] Furthermore, this method may also include: acquiring working environment data information of the law enforcement area, inputting the working environment data information of the law enforcement area into the database for data matching, acquiring image clarity data of each sub-area in the target area under different working parameters of the law enforcement recorder, sorting the image clarity data of each sub-area in the target area under different working parameters of the law enforcement recorder, acquiring the geographical location information of the area with the highest image clarity data, generating relevant recommendation information based on the geographical location information of the area with the highest image clarity data, and displaying the recommendation information in a specified manner. It should be noted that this method can recommend the most suitable area for law enforcement recorder recording during law enforcement, resulting in clearer video or image data.

[0098] In summary, this invention, by incorporating a ring-shaped defogging mechanism into the camera lens of a law enforcement recorder, enables law enforcement personnel to obtain clearer images or video data in areas with high humidity, heavy fog, or severe smog. The mechanism adaptively adjusts its operating parameters based on data from a fog sensor, saving energy while automatically removing fog and dirt from the camera lens, resulting in clearer video or image data acquired by the law enforcement recorder during law enforcement operations.

[0099] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

[0100] Based on the preferred embodiments of the present invention described above, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this invention is not limited to the contents of the specification, but must be determined according to the scope of the claims.

A control method for a law enforcement recorder with adaptive parameter adjustment function, characterized in that, The application of the law enforcement recorder according to claim 1 includes the following steps: The amount of fog on the camera lens is identified by a fog sensor, the amount of fog generated on the camera lens within a unit time is obtained, a fog amount threshold is set, and it is determined whether the amount of fog generated on the camera lens within the unit time is greater than the fog amount threshold. When the amount of fog generated on the camera lens within a unit time exceeds the fog amount threshold, the amount of fog cleared by the blower within a unit time under various operating parameters is obtained, a database is constructed, and the amount of fog cleared by the blower within a unit time under various operating parameters is input into the database for storage. The amount of fog generated on the camera lens within the unit time is input into the database for data acquisition. The working parameters of the blower are obtained when the amount of fog cleared within the unit time is greater than the amount of fog generated on the camera lens within the unit time. The blower is controlled by a control chip based on the operating parameters of the blower corresponding to the amount of fog cleared within a unit time being greater than the amount of fog generated on the camera lens within a unit time.

3. The control method for a law enforcement recorder with adaptive parameter adjustment function as described in claim 2, characterized in that, Also includes: The system acquires image data information collected by law enforcement recorders within a preset time period, and identifies the image data information collected by law enforcement recorders within the preset time period through a control chip to acquire image clarity data corresponding to each image data information collected by law enforcement recorders within the preset time period. The average image clarity data corresponding to the image data within the preset time is calculated based on the image clarity data corresponding to the image data information collected by each law enforcement recorder within the preset time, and an average image clarity data threshold is set. Determine whether the average image sharpness data corresponding to the image data within the preset time is greater than the average image sharpness data threshold. If it is greater, there is no need to adjust the working parameters of the law enforcement recorder when acquiring images. If the average image clarity data corresponding to the image data within the preset time is greater than the average image clarity data threshold, then the optimal working parameters for image acquisition under the current working environment are obtained, and the law enforcement recorder is adaptively controlled according to the optimal working parameters for image acquisition under the current working environment.
