Description

Technical Field

[0001] This invention relates to the field of video surveillance technology, and in particular to a control method and control device for surveillance equipment, as well as a surveillance system. Prior Technology

[0002] Currently, on-site monitoring via cameras has become one of the most important monitoring methods in the security surveillance field. Cameras record image information through image sensors and other components, which generate heat during operation. When cameras are used for extended periods, the operating time of the image sensors and other components inside the camera also increases, resulting in more heat generation.

[0003] Surveillance equipment is widely used in various fields. To ensure the real-time nature of monitoring, cameras typically need to operate 24 / 7. This prolonged operation exposes cameras to extreme high temperatures, which can lead to problems such as increased noise in the camera lens, focus drift, and color deviation, affecting image quality and stability. Furthermore, the high temperatures generated by the camera can damage internal electronic or optical components, such as image sensors, reducing the camera's lifespan. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a control method, control device and monitoring system for monitoring equipment, in contrast to the prior art.

[0005] To address the aforementioned technical problems, one technical solution adopted by this invention is to provide a control method for a monitoring device, comprising: capturing the monitoring image and weight setting range captured by the monitoring device through a monitoring screen and a weight acquisition module, and dividing the monitoring image into multiple sub-regions arranged in an array; setting a weight value for each sub-region according to the monitoring image and the weight setting range through a weight value setting module; wherein the weight value is within the weight setting range; controlling the monitoring device to capture the monitoring image in real time and capture the sub-movement value of each sub-region in real time through a sub-movement value acquisition module; and determining the monitoring power level of the monitoring device according to the sub-movement value and the weight value corresponding to each sub-region through a power level determination module, and controlling the monitoring device to operate at the monitoring power level.

[0006] Preferably, a weight value is set for each of the sub-regions based on the monitoring screen and the weight setting range; including: determining the current level of attention for each of the sub-regions based on the monitoring screen; and setting the weight setting value corresponding to the current level of attention as the weight value based on the mapping relationship between the level of attention and the weight setting value, wherein the weight setting value is located within the weight setting range.

[0007] Preferably, controlling the monitoring device to capture the monitoring screen in real time and to extract the sub-movement value of each sub-region in real time includes: controlling the monitoring device to capture the monitoring screen in real time, determining whether there are multiple sub-regions in the second monitoring screen that are different from the corresponding multiple sub-regions in the first monitoring screen, wherein the first monitoring screen is the monitoring screen captured by the monitoring device in the previous frame, and the second monitoring screen is the monitoring screen captured by the monitoring device in the next frame; if so, extracting the people or objects in each sub-region that are different from the multiple sub-regions in the first monitoring screen; determining whether the people or objects in each sub-region that are different from the multiple sub-regions in the first monitoring screen are all in the person whitelist; if so, determining that the sub-movement value of each sub-region is the second movement value.

[0008] Preferably, if the images of each sub-region in the second monitoring screen are the same as the images of the corresponding sub-regions in the first monitoring screen, then the sub-movement value of each sub-region is determined to be the second movement value.

[0009] Preferably, determining the monitoring power level of the monitoring device based on the sub-movement value and the weight value corresponding to each sub-region includes: multiplying the sub-movement value of the sub-region by the weight value as the sub-comprehensive movement value of the sub-region; calculating the current total movement amount of the monitoring screen based on the sub-comprehensive movement value corresponding to each sub-region; and determining the power level corresponding to the current total movement amount as the monitoring power level based on the mapping relationship between the current total movement amount and the power level.

[0010] Preferably, determining the current total movement of the monitoring screen based on the sub-comprehensive movement value corresponding to each sub-region includes: taking the sum of multiple sub-comprehensive movement values ​​as the current total movement.

[0011] Preferably, the control method for the monitoring device further includes: when the monitoring device is operating at the monitoring power level and the monitoring power level is less than the maximum power level of the monitoring device, capturing the sound intensity of the environment in which the monitoring device is located; determining whether the sound intensity is greater than a preset intensity; if so, determining whether the sound in the environment in which the monitoring device is located belongs to a sound whitelist; if so, controlling the monitoring device to operate at the monitoring power level.

[0012] Preferably, if the ambient sound of the monitoring device is not in the sound whitelist, the monitoring device is controlled to operate at the highest power level.

[0013] Secondly, the present invention provides a control device for a monitoring device, comprising: a monitoring screen and a weight acquisition module, used to acquire the monitoring screen captured by the monitoring device and a weight setting range, and divide the monitoring screen into multiple sub-regions arranged in an array; a weight value setting module, used to set a weight value for each sub-region according to the monitoring screen and the weight setting range; the weight value is located within the weight setting range; a sub-movement value acquisition module, used to control the monitoring device to capture the monitoring screen in real time and acquire the sub-movement value of each sub-region in real time; and a power level determination module, used to determine the monitoring power level of the monitoring device according to the sub-movement value and the weight value corresponding to each sub-region, and control the monitoring device to operate at the monitoring power level.

[0014] Thirdly, the present invention provides a monitoring system, comprising: a monitoring device and a controller; the controller is communicatively connected to the monitoring device; the controller is used to execute the control method of the monitoring device described in the first aspect.

[0015] One of the beneficial effects of this invention is that the control method, control device, and monitoring system for monitoring equipment provided by this invention divides the monitoring screen captured by the monitoring equipment into multiple sub-regions arranged in an array. Based on the user's level of attention to each sub-region in the monitoring screen, a corresponding weight value is assigned to each sub-region. Then, based on the sub-movement value and weight value of each sub-region, the corresponding monitoring power level of the monitoring equipment is determined. During the monitoring process, the sub-movement values ​​of each sub-region may be the same or different, resulting in different determined monitoring power levels at different times during the monitoring process. This allows the monitoring equipment to operate at a higher or lower monitoring power level at different times during the working period. When the monitoring equipment operates at a lower monitoring power level, the temperature generated by the monitoring equipment can be reduced, and the heat of the components in the monitoring equipment can be released during this stage, reducing the operating time of the monitoring equipment under extreme temperature conditions, improving the monitoring quality of the monitoring equipment, and extending the service life of the monitoring equipment.

[0027] Example 1

[0028] This invention provides a control method for a monitoring device, suitable for situations requiring real-time adjustment of the monitoring power level. This method can be executed by a control device for the monitoring device provided in this invention, which can be implemented in hardware and / or software. Figure 1 is a flowchart of a first control method for a monitoring device provided in this invention. As shown in Figure 1, the control method for the monitoring device includes:

[0029] S101. Capture the monitoring screen captured by the monitoring equipment and the weight setting range, and divide the monitoring screen into multiple sub-regions arranged in an array.

[0030] The monitoring equipment includes devices such as camera lenses, and the monitoring screen represents the image that the monitoring equipment can capture at its current location when it is working. The weight setting range can be set according to actual needs. In a preferred embodiment, the weight setting range can be 0 to 9, but it is not limited to this.

[0031] Specifically, during the installation of surveillance equipment, to ensure that the captured images reflect the actual monitoring area, the position of the equipment is typically adjusted, and images are captured from various locations. Once the captured images meet the requirements, the position of the equipment is fixed. With the position fixed, the images captured at each moment reflect the real-time situation of the same monitoring area. After the equipment is powered on, the image processing module captures the images and then divides them into multiple sub-regions arranged in an array, facilitating the subsequent setting of weight values ​​for each sub-region. The size of each sub-region can be set according to parameters such as the size of the surveillance image. For example, if the surveillance image has a resolution of 1280×720 pixels, it can be divided into 8 rows and 6 columns, with each sub-region having a resolution of 160×120 pixels.

[0032] S102. Based on the monitoring screen and weight setting range, set weight values ​​for each sub-area.

[0033] The weight values ​​are within the weight setting range.

[0034] Specifically, based on the image content in each sub-region of the monitoring screen and the user's level of attention to each sub-region, corresponding weight values ​​can be assigned to each sub-region. Ideally, the higher the user's level of attention to a sub-region, the larger the weight value assigned to that sub-region; conversely, the lower the user's level of attention to a sub-region, the smaller the weight value assigned to that sub-region. The weight value represents the user's level of attention to that sub-region.

[0035] S103. Control the monitoring equipment to capture the monitoring screen in real time and extract the sub-movement values ​​of each sub-area in real time.

[0036] The sub-motion value represents the difference between the previous frame and the next frame.

[0037] Specifically, the monitoring equipment captures real-time monitoring images, including each frame of the monitoring image. By comparing the previous frame and the next frame of the same sub-region, the sub-motion value of each sub-region is determined. For example, if the next frame of a sub-region is the same as the previous frame, the sub-motion value of that sub-region is 0; if the next frame of a sub-region is different from the previous frame, the sub-motion value of that sub-region is 1.

[0038] S104. Based on the sub-movement value and weight value corresponding to each sub-region, determine the monitoring power level of the monitoring equipment and control the monitoring equipment to operate at the monitoring power level.

[0039] The higher the monitoring power level, the greater the heat generated by the internal components of the monitoring equipment during operation.

[0040] Specifically, the current total movement value of the monitored image can be calculated based on the sub-movement value and weight value corresponding to each sub-region. Then, the monitoring power level of the monitoring equipment is determined based on this current total movement value. The current total movement value represents the amount of change in the monitored image; the larger the current total movement value, the greater the amount of change in the monitored image. A higher current total movement value indicates a higher determined monitoring power level, ensuring the clarity of the captured image when the monitoring equipment operates at a higher monitoring power level. Conversely, a lower current total movement value indicates a lower determined monitoring power level, reducing the heat generated by the monitoring equipment and allowing it to release heat generated previously, thus minimizing the impact of temperature on the equipment's operation. This allows the monitoring equipment to operate at different monitoring power levels during the working period, based on the sub-movement value and weight value corresponding to each sub-region, preventing the equipment from continuously operating at a high monitoring power level, which could lead to insufficient heat release and affect the monitoring quality.

[0041] The technical solution of this invention divides the monitoring screen captured by the monitoring device into multiple sub-regions arranged in an array. Based on the user's level of attention to each sub-region, a corresponding weight value is assigned to each sub-region. Then, based on the sub-movement value and weight value of each sub-region, the monitoring power level of the monitoring device is determined. During monitoring, the sub-movement values ​​of each sub-region may be the same or different, resulting in different determined monitoring power levels at different times during the monitoring process. This allows the monitoring device to operate at a higher or lower monitoring power level at different times within the working period. When the monitoring device operates at a lower monitoring power level, the temperature generated by the monitoring device can be reduced, and the heat from the components in the monitoring device can be released during this stage. This reduces the operating time of the monitoring device under extreme temperature conditions or prevents the monitoring device from operating under extreme temperature conditions, thereby improving the monitoring quality and lifespan of the monitoring device.

[0042] Example 2

[0043] Based on the above embodiments, this embodiment of the invention describes the setting of weight values ​​for each sub-region according to the monitoring screen and weight setting range. Figure 2 is a flowchart of a second type of control method for a monitoring device provided by this embodiment of the invention. As shown in Figure 2, the control method for the monitoring device includes:

[0044] S201. Capture the monitoring screen captured by the monitoring equipment and the weight setting range, and divide the monitoring screen into multiple sub-regions arranged in an array.

[0045] S202. Based on the monitoring footage, determine the current level of attention for each sub-area.

[0046] Specifically, the monitoring screen can be divided into sub-regions based on its features. Preferably, when the monitoring screen includes features such as windows or walls, since outsiders can enter other areas of the screen through windows or walls, the current attention level of the area containing windows or walls can be set to high attention. When the monitoring screen includes features such as doors, since outsiders may enter other areas of the screen through high-attention sub-regions and then through doors, the current attention level of the area containing doors can be set to relatively high attention. Since outsiders may enter relatively high-attention sub-regions through high-attention sub-regions, all sub-regions between high-attention and relatively high-attention sub-regions can be set to low attention. Other sub-regions that do not require user attention should have their current attention level set to low attention. The level of attention can be represented numerically. For example, a value between 0% and 100% can be used to represent the level of attention, 80% to 100% can represent high attention, 50% to 80% can represent relatively high attention, 10% to 50% can represent low attention, and below 10% can represent low attention. Other settings are also possible, but no specific limitations are made here.

[0047] It is understandable that the current attention level set for each sub-area based on the monitoring screen can be directly set by the user, or the monitoring equipment's internal processing module can first divide the attention level for each sub-area based on the monitoring screen according to its internal processing logic. If the user agrees with the processing module's division of attention level for each sub-area, then the processing module's division result shall prevail. If the user does not agree with the processing module's division of attention level for each sub-area, the user can modify the processing module's division result, and the modified division result shall prevail.

[0048] S203. Based on the mapping relationship between the current level of attention and the weight setting value, set the weight setting value corresponding to the current level of attention as the weight value.

[0049] The weight setting value is within the weight setting range. The mapping relationship can be a curve of attention level and weight setting value or a correspondence table of attention level and weight setting value, which can be obtained through experiments or experience.

[0050] Specifically, when the mapping relationship is a curve representing the degree of attention and the weight setting value, after extracting the current degree of attention, you can directly compare it with the curve representing the degree of attention and the weight setting value to determine the weight setting value on the curve corresponding to the current degree of attention. Alternatively, when the mapping relationship is a table representing the degree of attention and the weight setting value, after extracting the current degree of attention, you can directly look up the corresponding weight setting value in the table and use that weight setting value as the weight value. The weight value is directly proportional to the degree of attention; that is, the higher the degree of attention, the larger the corresponding weight value.

[0051] For example, Figure 8 is a schematic diagram of the structure of a monitoring screen provided in an embodiment of the present invention. As shown in Figure 8, the weight setting range is 0~9. The weight value of the sub-region with high attention is 9, the weight value of the sub-region with relatively high attention is 3, the weight value of the sub-region with low attention is 1, and the weight value of the sub-region with low attention is 0.

[0052] S204. Control the monitoring equipment to capture the monitoring screen in real time and extract the sub-movement values ​​of each sub-area in real time.

[0053] S205. Based on the sub-movement value and weight value corresponding to each sub-region, determine the monitoring power level of the monitoring equipment and control the monitoring equipment to operate at the monitoring power level.

[0054] The technical solution of this invention assigns corresponding weight values ​​to each sub-region of the monitoring screen based on the features in the monitoring screen and the user's level of attention to each feature. In this way, the user's level of attention to each sub-region is numerically quantified through the weight values, thereby improving the accuracy of the monitoring power level determination when subsequently calculating and judging the monitoring power level of the monitoring equipment based on the weight values.

[0055] Example 3

[0056] Based on the above embodiments, this embodiment of the invention describes the control and monitoring equipment to capture monitoring images in real time and extract sub-movement values ​​of each sub-region in real time. Figure 3 is a flowchart of a third type of control method for a monitoring device provided by this embodiment of the invention. As shown in Figure 3, the control method for the monitoring device includes:

[0057] S301. Capture the monitoring screen captured by the monitoring device and the weight setting range, and divide the monitoring screen into multiple sub-regions arranged in an array.

[0058] S302. Based on the monitoring screen and weight setting range, set weight values ​​for each sub-area.

[0059] The weight values ​​are within the weight setting range.

[0060] S303. Control the monitoring equipment to capture the monitoring screen in real time, and determine whether there are multiple sub-areas in the second monitoring screen that are different from the corresponding multiple sub-areas in the first monitoring screen; if yes, then execute S304; if no, then execute S308.

[0061] The first monitoring screen is the previous frame captured by the monitoring equipment, and the second monitoring screen is the next frame captured by the monitoring equipment. The dynamic screen is composed of multiple static frames captured by the monitoring equipment per unit time. In other words, the video screen captured by the monitoring equipment for the user is a dynamic screen formed by continuously playing each static frame captured by the monitoring equipment.

[0062] Specifically, the monitoring equipment captures surveillance footage in real time, extracting each frame. By comparing the next frame (second monitoring frame) with the previous frame (first monitoring frame), if multiple sub-regions in the second monitoring frame differ from the corresponding sub-regions in the first monitoring frame, it is determined that movement of people or objects exists in the area monitored by the equipment. If all sub-regions in the second monitoring frame are identical to their corresponding sub-regions in the first monitoring frame, it is determined that no movement of people or objects exists in the area monitored by the equipment.

[0063] S304. Extract the people or objects in each sub-region of the second monitoring screen that are different from the images of multiple sub-regions in the first monitoring screen.

[0064] Specifically, if several sub-areas in the second monitoring screen differ from the corresponding sub-areas in the first monitoring screen, it indicates the presence of movement of people or objects within the monitored area. Based on this, it's currently impossible to determine whether these people or objects are unauthorized personnel or whether they pose a threat to the security of the monitored area. Therefore, the people or objects in the sub-areas that differ from those in the first monitoring screen can be extracted and analyzed to determine the power level of the monitoring equipment.

[0065] S305. Determine whether the people or objects in each sub-area that are different from the images of multiple sub-areas in the first monitoring screen are all in the whitelist of people; if yes, then execute S306; if no, then execute S307.

[0066] The whitelist of people includes characteristics of specific individuals and / or specific objects. These specific individuals and objects will not affect the security of the monitored area, and the specific individuals and / or specific objects are set according to the user's actual needs. For example, if the monitoring equipment is installed in a residential residence, the specific individuals can include permanent residents of that residence, and the specific objects can include animals such as cats or dogs residing in that residence. Others are also possible, and no specific limitations are made here. Characteristics of specific individuals include facial features and height characteristics, while characteristics of specific objects include animal silhouettes, and these can be set according to actual needs, without specific limitations made here.

[0067] Specifically, the people or objects in the sub-regions that differ from the first monitoring screen can be compared with specific people or objects in the whitelist. If all the people or objects in the second monitoring screen match the characteristics of the specific people or objects in the whitelist, then all the people or objects in the sub-regions that differ from the first monitoring screen are in the whitelist. If some of the people or objects in the second monitoring screen do not match the characteristics of the specific people or objects in the whitelist, then at least some of the people or objects in the sub-regions that differ from the first monitoring screen are not in the whitelist.

[0068] S306. Determine the sub-movement value of each sub-region as the second movement value.

[0069] Among them, the second movement value can be a fixed value and can be determined according to actual needs. Preferably, the second movement value is zero, or it can be other values, which are not specifically limited here.

[0070] Specifically, when the people or objects formed in each sub-region different from the partial multiple sub-regions in the first monitoring screen all exist in the person white list, it means that no outsiders or foreign objects appear in the area monitored by the monitoring device, and only the people or objects in the person white list are carrying out normal work or life in the monitoring area, etc., which has no impact on the security of the monitoring area. At this time, the sub-movement values of each sub-region where the screen has changed and the screen has not changed can be set to the second movement value, that is, the sub-region where the screen has changed is regarded as not having moved. In this way, when the moving people or objects in the monitoring screen belong to the person white list, the contribution of these people or objects to the sub-movement value can be ignored, preventing the movement of the people or objects in the person white list from causing the monitoring device to continuously be in a high power level, thereby affecting the service life of the monitoring device.

[0071] S307. Determine the sub-movement value of each sub-region where the people or objects that do not belong to the person white list are located as the first movement value, and determine the sub-movement value of each sub-region where the people or objects that belong to the person white list are located as the second movement value.

[0072] Among them, the first movement value is greater than the second movement value. The first movement value can be a fixed value or a non-fixed value, and the first movement value can be determined according to the actual movement situation of each sub-region. Preferably, the value range of the first movement value is A, where 0 < A ≤ 1. Exemplarily, the first movement value is 1 and the second movement value is 0, or it can be other values, which are not specifically limited here. The first movement value can be determined according to the difference degree between the next frame of the screen and the previous frame in the sub-region. Exemplarily, the larger the ratio of the area of the next frame different from the previous frame in the sub-region to the total area of the sub-region, the larger the first movement value. It is also possible to directly use the ratio of the area of the next frame different from the previous frame in the sub-region to the total area of the sub-region as the first movement value. The method of determining the first movement value according to the actual movement situation of each sub-region can also be other methods, which are not specifically limited here.

[0073] Specifically, if people or objects in sub-regions that differ from the images in the first monitoring screen are not on the whitelist, it indicates that outsiders have entered the monitored area. In this case, the sub-movement value of the sub-region containing people or objects on the whitelist can be determined as the same as the second movement value of the sub-region where the image has not moved. The sub-movement values ​​of the sub-regions containing people or objects not on the whitelist can be determined as the first movement value, which is greater than the second movement value. This is so that the monitoring power level of the monitoring equipment can be determined subsequently based on the first and second movement values.

[0074] S308. Determine that the sub-movement values ​​of each sub-region are the second movement values.

[0075] Specifically, when the images in each sub-area of ​​the second monitoring screen are the same as the images in the corresponding sub-areas of the first monitoring screen, it indicates that there is no movement of people or objects in the area monitored by the monitoring equipment. In this case, the sub-movement value of each sub-area can be judged as the second movement value.

[0076] S309. Based on the sub-movement value and weight value corresponding to each sub-region, determine the monitoring power level of the monitoring equipment and control the monitoring equipment to operate at the monitoring power level.

[0077] In the technical solution of this invention embodiment, if the images of each sub-region in the second monitoring screen are identical to the images of the corresponding sub-regions in the first monitoring screen, then the sub-movement values ​​of each sub-region are determined to be the second movement values. By setting a whitelist of persons, when some sub-regions in the second monitoring screen differ from multiple sub-regions in the corresponding portion of the first monitoring screen, the persons or objects constituting those sub-regions in the second monitoring screen that differ from the images of multiple sub-regions in the first monitoring screen are extracted. The extracted persons or objects are compared with those in the whitelist. If all extracted persons or objects belong to the whitelist, then the sub-movement values ​​of each sub-region are determined to be the second movement values, identical to the sub-movement values ​​of the sub-regions that have not moved. If any of the extracted persons or objects are not in the whitelist, then the sub-movement values ​​of the sub-regions containing the persons or objects not in the whitelist are determined to be the first movement values, and the sub-movement values ​​of the sub-regions containing the persons or objects in the whitelist are determined to be the second movement values. In this way, by setting a whitelist of people, the movement of people or objects on the whitelist within the monitoring area will not affect the security of the monitoring area. If a person or object in a sub-area where the image changes belongs to the whitelist, then the sub-area where the image changes is considered as if the image has not changed. In subsequent determination of the monitoring power level of the monitoring equipment based on the sub-movement value, the accuracy of the determination of the monitoring power level of the monitoring equipment can be improved, thereby extending the service life of the monitoring equipment.

[0078] Example 4

[0079] Based on the above embodiments, this embodiment of the invention describes how to determine the monitoring power level of the monitoring device according to the sub-movement value and weight value corresponding to each sub-region. Figure 4 is a flowchart of the fourth monitoring device control method provided by this embodiment of the invention. As shown in Figure 4, the monitoring device control method includes:

[0080] S401. Capture the monitoring screen captured by the monitoring device and the weight setting range, and divide the monitoring screen into multiple sub-regions arranged in an array.

[0081] S402. Based on the monitoring screen and weight setting range, set weight values ​​for each sub-area.

[0082] The weight values ​​are within the weight setting range.

[0083] S403. Control the monitoring equipment to capture the monitoring screen in real time and extract the sub-movement values ​​of each sub-area in real time.

[0084] S404. The product of the sub-movement value and the weight value of each sub-region is taken as the sub-comprehensive movement value of each sub-region.

[0085] Specifically, the sub-aggregate movement value is the movement amount after amplifying or reducing the sub-movement value according to the weight value. For example, if the sub-movement value of a sub-region is 1, but the weight value of the sub-region is 0, then the sub-aggregate movement value of that sub-region is 0. If the sub-movement value of a sub-region is 0.8, but the weight value of the sub-region is 1, then the sub-aggregate movement value of that sub-region is 0.8. If the sub-movement value of a sub-region is 0, and the weight value is 9, then the sub-aggregate movement value of that sub-region is 0. If the sub-movement value of a sub-region is 1, and the weight value is 3, then the sub-aggregate movement value of that sub-region is 3.

[0086] S405. Calculate the current total movement on the monitoring screen based on the sub-comprehensive movement value corresponding to each sub-area.

[0087] Specifically, the sub-comprehensive motion value of a sub-region can reflect the motion reference amount of the sub-region, and the current total motion amount can reflect the motion reference amount of the monitoring screen. In a preferred embodiment, the sum of multiple sub-comprehensive motion values ​​of multiple sub-regions can be used as the current total motion amount of the monitoring screen, so as to determine the monitoring power level based on the current total motion amount.

[0088] It should be noted that matrices can be used to represent the sub-movement values, weight values, and sub-comprehensive movement values ​​of each sub-region. For example, the monitoring screen is divided into m rows and n columns, comprising m×n sub-regions. Matrix A represents the sub-movement value of each sub-region in the monitoring screen, matrix B represents the weight value of each sub-region, and matrix C represents the sub-comprehensive movement value of each sub-region, respectively:

[0089] A= ;B= ;

[0090] C=

[0091] Where matrix C is the Hadamard product of matrix A and matrix B, that is, C = [ ], i∈[1,m], j∈[1,n]. The current total movement P of the monitoring screen is the sum of all values ​​in matrix C, that is, P= .

[0092] S406. Based on the mapping relationship between the current total movement amount and the power level, determine the power level corresponding to the current total movement amount as the monitoring power level, and control the monitoring device to operate at the monitoring power level.

[0093] Among them, the power level is in a direct proportional relationship with the current total movement amount. That is, the larger the current total movement amount P is, the higher the power level. The higher the power level, the higher the monitoring quality of the monitoring device. Different power levels correspond to different video resolutions, video frame rates, and audio sampling rates, etc. The mapping relationship can be a line graph of the current total movement amount and the power level, or a corresponding table of the current total movement amount and the power level, etc., which can be obtained through experiments or experience. Exemplarily, as shown in Table 1, when the current total movement amount is B, when B = 0, the corresponding power level is the fourth power level; when 0 < B ≤ 36, the corresponding power level is the third power level; when 36 < B ≤ 92, the corresponding power level is the second power level; when B > 92, the corresponding power level is the first power level. The working parameters corresponding to the power level further include others. Exemplarily, at the first power level, the infrared LED power of the monitoring device in the night vision field is 100% of the rated power; at the second power level, the infrared LED power of the monitoring device in the night vision field is 80% of the rated power; at the third power level, the infrared LED power of the monitoring device in the night vision field is 60% of the rated power; at the fourth power level, the infrared LED power of the monitoring device in the night vision field is 40% of the rated power. The working parameters corresponding to the power level can also be others, and can be set according to actual needs, and are not specifically limited here.

[0094] Table 1: Current total movement amount Power level Video resolution (px) Video frame rate (f / s) Audio sampling rate (kHz) >92 One 3840×2160 25 96 36 - 92 Two 2048×1536 18 48 0 - 36 Three 1290×1080 10 twenty four 0 Four 1280×720 5 8

[0095] Specifically, when the mapping relationship is a curve of the current total movement P versus power level, after retrieving the current total movement, the power level on the curve corresponding to the current total movement can be determined directly by comparing it with the curve of the total movement P. Alternatively, when the mapping relationship is a table of correspondences between the current total movement and power level, after retrieving the current total movement, the power level corresponding to the current total movement can be directly looked up in the table and determined as the monitoring power level. After determining the monitoring power level, the monitoring equipment is controlled to operate at the monitoring power level, so that the monitoring equipment adjusts its current operating parameters according to the current total movement, thereby reducing the operating temperature of the monitoring equipment by avoiding constant operation at a high monitoring power level.

[0096] The technical solution of this invention uses the product of the sub-movement value and the weight value of each sub-region as the sub-comprehensive movement value of each sub-region. Then, the sum of the multiple sub-comprehensive movement values ​​of multiple sub-regions is used as the current total movement amount on the monitoring screen. During the total monitoring period, based on the mapping relationship between the current total movement amount and the power level, the power level corresponding to the current total movement amount can be determined as the monitoring power level. This allows the monitoring device to adjust the monitoring power level in real time according to changes in the current screen, avoiding prolonged operation under high-temperature conditions and extending the lifespan of the monitoring device.

[0097] Example 5

[0098] Based on the above embodiments, this embodiment of the invention describes the case where the monitoring device operates at a monitoring power level that is lower than the highest power level of the monitoring device. Figure 5 is a flowchart of a fifth control method for a monitoring device provided by this embodiment of the invention. As shown in Figure 5, the control method for the monitoring device includes:

[0099] S501: Capture the monitoring screen captured by the monitoring device and the weight setting range, and divide the monitoring screen into multiple sub-regions arranged in an array.

[0100] S502. Based on the monitoring screen and weight setting range, set weight values ​​for each sub-area.

[0101] The weight values ​​are within the weight setting range.

[0102] S503: Control the monitoring equipment to capture the monitoring screen in real time and extract the sub-motion values ​​of each sub-area in real time.

[0103] S504. Based on the sub-movement value and weight value corresponding to each sub-region, determine the monitoring power level of the monitoring equipment and control the monitoring equipment to operate at the monitoring power level.

[0104] S505. When the monitoring equipment is operating at the monitoring power level, and the monitoring power level is less than the maximum power level of the monitoring equipment, the sound intensity of the environment in which the monitoring equipment is located is captured.

[0105] Among them, when the monitoring equipment operates at its highest power level, the monitoring equipment generates a high amount of heat.

[0106] Specifically, when the current monitoring power level of the surveillance equipment is lower than the maximum power level, it indicates that the total movement within the monitored area is relatively small. In this case, a sound detection device can be used to capture the sound intensity of the environment surrounding the surveillance equipment. This allows for the assessment of the surrounding situation and enables the monitoring equipment to adjust its operating status in advance before any person or object emitting the sound enters the monitored area, facilitating timely detection and improving the reliability of the surveillance system. Microphones or other sound detection devices can be installed in the surveillance equipment to capture the decibel levels of the ambient sound.

[0107] S506. Determine if the sound intensity is greater than the preset intensity; if so, execute S507.

[0108] The preset intensity can be a fixed value, which can be set according to actual needs. For example, the preset decibel is 50 dB.

[0109] Specifically, when the sound intensity is greater than the preset intensity, it indicates that an abnormal event may have occurred in the environment where the monitoring equipment is located (a cry for help from a person or an alarm sound from an alarm), and the abnormal event has not yet entered the monitoring area of ​​the monitoring equipment.

[0110] S507. Determine whether the sound of the environment where the monitoring device is located is on the sound whitelist; if yes, proceed to S508; if no, proceed to S509.

[0111] The sound whitelist includes specific sounds, which can be configured based on the monitoring environment of the surveillance device. For example, if the surveillance device is set up in a home with a cat, the cat's meow can be added to the sound whitelist. If the environment where the surveillance device is located has the sound of a specific animal (such as cicadas) during a certain season, the sound of that specific animal can be added to the sound whitelist.

[0112] Specifically, the system compares the ambient sound of the monitored environment with sounds in a whitelist. If the sound in the current environment matches the characteristics of sounds in the whitelist, then the sound emitted in the current environment belongs to the whitelist. If the sound in the current environment does not match the characteristics of sounds in the whitelist, then the sound emitted in the current environment does not belong to the whitelist. Sound characteristics include timbre and frequency, among others.

[0113] S508, Control and monitor equipment to operate at monitoring power levels.

[0114] Specifically, if the sound emitted in the current environment is on the sound whitelist, it means that no abnormal event has occurred in the environment where the monitoring equipment is located. At this time, the monitoring equipment can be controlled to operate at the current monitoring power level.

[0115] S509. Control and monitor equipment to operate at the highest power level.

[0116] Specifically, if the sound emitted in the current environment is not on the sound whitelist, it indicates that an abnormal event has occurred in the environment where the monitoring equipment is located. At this time, the monitoring equipment can be controlled to operate at the highest power level so that when the abnormal event enters the monitoring area of ​​the monitoring equipment, the monitoring equipment can capture a clear picture of the abnormal event for subsequent verification.

[0117] In this embodiment of the invention, when the current monitoring power level of the monitoring device is less than its maximum power level, it indicates that the total movement of the monitored image is small. In this case, the sound intensity of the environment where the monitoring device is located can be captured by a sound detection device. When the sound intensity is greater than a preset intensity and the sound is on a whitelist, it indicates that no abnormal event has occurred in the environment where the monitoring device is located, and the monitoring device continues to operate at its current monitoring power level. When the sound intensity is greater than a preset intensity and the sound is not on a whitelist, it indicates that an abnormal event has occurred in the environment where the monitoring device is located. In this case, the monitoring device is controlled to operate at its highest power level so that when an abnormal event enters the monitoring area, the monitoring device can capture a clear image of the abnormal event for subsequent verification.

[0121] The weight value setting module 12 is used to set weight values ​​for each sub-area based on the monitoring screen and the weight setting range; the weight values ​​are within the weight setting range.

[0127] [Beneficial Effects of the Examples]

[0128] One of the beneficial effects of this invention is that the control method, control device, and monitoring system for monitoring equipment provided by this invention divides the monitoring screen captured by the monitoring equipment into multiple sub-regions arranged in an array. Based on the user's attention to each sub-region in the monitoring screen, a corresponding weight value is set for each sub-region. Then, based on the sub-movement value and weight value of each sub-region, the corresponding monitoring power level of the monitoring equipment is determined. During the monitoring process, the sub-movement values ​​of each sub-region may be the same or different, resulting in different determined monitoring power levels at different times during the monitoring process. This allows the monitoring equipment to operate at a higher or lower monitoring power level at different times during the working period. When the monitoring equipment operates at a lower monitoring power level, the temperature generated by the monitoring equipment can be reduced, and the heat of the components in the monitoring equipment can be released during this stage. This reduces the operating time of the monitoring equipment under extreme temperature conditions or prevents the monitoring equipment from operating under extreme temperature conditions, thereby improving the monitoring quality and service life of the monitoring equipment.
