[0002] At present, on-site monitoring through cameras has become one of the most important monitoring methods in the field of security monitoring. Cameras record image information through components such as image sensors, which generate heat when in operation. When the camera is used for a long time, the working time of components such as image sensors in the camera will also increase accordingly, thereby generating more heat.

[0049] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0050] Embodiment 1

[0051] An embodiment of the present invention provides a control method for a monitoring device, which is suitable for real-time adjustment of the monitoring power level of the monitoring device. The method can be executed by the control device of the monitoring device provided by the embodiment of the present invention, and the control device of the monitoring device can be implemented in the form of hardware and / or software. Figure 1 A flowchart of a control method for a first monitoring device provided by an embodiment of the present invention, such as Figure 1 As shown, the control method of the monitoring device includes:

[0052] S101, obtaining a monitoring screen captured by a monitoring device and a weight setting range, and dividing the monitoring screen into a plurality of sub-areas arranged in an array.

[0053] The monitoring device includes a camera and other devices, and the monitoring screen represents the image that the monitoring device can obtain at the current position when the monitoring device is working. The weight setting range can be set according to actual needs. In an optional embodiment, the weight setting range can be 0 to 9, or other, which is not specifically limited here.

[0054] Specifically, when installing the monitoring device, in order to make the image captured by the monitoring device reflect the situation of the monitoring area actually required, the position of the monitoring device is usually adjusted, and the monitoring screen captured by the monitoring device at various positions is obtained. When the monitoring screen captured by the monitoring device meets the actual needs, the position of the monitoring device is fixed. After the position of the monitoring device is fixed, the monitoring screen obtained by the monitoring device at each moment reflects the real-time situation of the same monitoring area. When the monitoring device is turned on, the monitoring screen can be obtained through the image processing module in the monitoring device, and then the monitoring screen is divided into a plurality of sub-areas arranged in an array according to actual needs, so as to facilitate the subsequent setting of weight values ​​for each sub-area. The size of each sub-area can be set according to parameters such as the size of the monitoring screen. For example, if the length of the monitoring screen is 120cm and the width is 90cm, the monitoring screen is divided into 8 rows and 6 columns, and the size of each sub-area is 15cm×15cm.

[0055] S102: Set a weight value for each sub-area according to the monitoring screen and the weight setting range.

[0056] Among them, the weight value is within the weight setting range.

[0057] Specifically, a corresponding weight value can be set for each sub-region in the monitoring screen according to the screen image in each sub-region in the monitoring screen and the user's attention to each sub-region. Preferably, the higher the user's attention to the sub-region, the greater the weight value set for the sub-region, and the lower the user's attention to the sub-region, the smaller the weight value set for the sub-region. The weight value indicates the user's attention to the sub-region.

[0058] S103, controlling the monitoring device to capture the monitoring screen in real time, and obtaining the sub-movement value of each sub-area in real time.

[0059] The sub-movement value indicates the difference between the previous frame and the next frame.

[0060] Specifically, the monitoring screen captured by the monitoring device in real time includes the monitoring screen corresponding to each frame, and the sub-movement value of each sub-area is determined by comparing the previous frame and the next frame in the same sub-area. For example, if the next frame of the sub-area is the same as the previous frame, the sub-movement value of the sub-area is 0, and if the next frame of the sub-area is different from the previous frame, the sub-movement value of the sub-area is 1.

[0061] S104: Determine a monitoring power level of the monitoring device according to the sub-movement value and the weight value corresponding to each sub-area, and control the monitoring device to operate at the monitoring power level.

[0062] Among them, the higher the monitoring power level, the greater the heat generated by the internal components of the monitoring device when working.

[0063] Specifically, the total movement of the current monitoring screen can be determined according to the sub-movement value and weight value corresponding to each sub-area, and then the monitoring power level of the monitoring device can be determined according to the total movement. The total movement represents the change of the monitoring screen. The larger the total movement, the larger the change of the current monitoring screen. When the total movement is larger, the higher the monitoring power level is determined, so that when the monitoring device is controlled to operate at a higher monitoring power level, the clarity of the monitoring device's capture of the monitoring screen can be guaranteed. When the total movement is lower, the lower the monitoring power level is determined, so that when the monitoring device is controlled to operate at a lower monitoring power level, the heat generated by the monitoring device can be reduced, so that the heat previously generated by the monitoring device can be released in this stage, and the temperature can be reduced. The working effect of the monitoring device. In this way, the monitoring device can work at different monitoring power levels according to the sub-movement value and weight value corresponding to each sub-area during the working time period, so as to avoid the monitoring device from continuously operating at a higher monitoring power level, resulting in the heat generated by the monitoring device being unable to be released in time, affecting the monitoring quality of the monitoring device.

[0064] The technical solution of the embodiment of the present invention is to divide the monitoring screen acquired by the monitoring device into multiple sub-areas arranged in an array, and set a corresponding weight value for each sub-area according to the user's attention to each sub-area in the monitoring screen, and then determine the corresponding monitoring power level of the monitoring device according to the sub-movement value and weight value of each sub-area. During the monitoring process, the sub-movement values ​​of each sub-area may be the same or different, so that at each moment in the monitoring process, the determined monitoring power level is different, and then the monitoring device is operated at a higher or lower monitoring power level at different moments in the working time period. When the monitoring device is operated at a lower monitoring power level, the temperature generated by the monitoring device can be reduced, and the heat of the components in the monitoring device can be released at this stage, reducing the working time of the monitoring device under extreme temperature conditions, or avoiding the monitoring device from working under extreme temperature conditions, thereby improving the monitoring quality of the monitoring device and the service life of the monitoring device.

[0065] Embodiment 2

[0066] On the basis of the above-mentioned embodiment, the embodiment of the present invention describes the case of setting a weight value for each sub-area according to a monitoring screen and a weight setting range. Figure 2 A flow chart of a second method for controlling a monitoring device provided by an embodiment of the present invention, such as Figure 2 As shown, the control method of the monitoring device includes:

[0067] S201, obtaining a monitoring screen captured by a monitoring device and a weight setting range, and dividing the monitoring screen into a plurality of sub-areas arranged in an array.

[0068] S202: Determine the current attention level of each sub-area according to the monitoring screen.

[0069] Specifically, each sub-area can be divided according to the image features in the monitoring image. Preferably, when the monitoring image includes features such as windows or walls, since outsiders can enter other areas of the monitoring image through windows or walls, the current attention level of the area where the windows or walls in the monitoring image are located can be set to a high attention level. When the monitoring image includes features such as doors, after outsiders enter other areas of the monitoring image through sub-areas with high attention levels, they may enter other areas of the monitoring image through features such as doors, and the current attention level of the area where the doors are located can be set to a high attention level. Since outsiders may enter sub-areas with high attention levels through sub-areas with high attention levels, the current attention levels of each sub-area between the sub-area with high attention levels and the sub-area with high attention levels in the direction from the sub-area with high attention levels to the sub-area with high attention levels can be set to low attention sub-areas. The current attention levels of other sub-areas that do not require user attention are set to a low attention level. The degree of attention can be represented by a numerical value. For example, a numerical value between 0% and 100% can be used to represent the degree of attention, with 100% representing a higher degree of attention, 80% representing a high degree of attention, 50% representing a lower degree of attention, and 10% representing a low degree of attention. Other settings are also possible and are not specifically limited here.

[0070] It is understandable that the current attention level set for each sub-area according to the monitoring screen can be set directly by the user, or the processing module inside the monitoring device first divides the attention level of each sub-area according to the monitoring screen based on the internal processing logic. If the user approves the division of the attention level of each sub-area by the processing module, the division result of the processing module shall prevail. If the user does not approve the division of the attention level of each sub-area by the processing module, the user can modify the attention level division result of the processing module, and the modified attention level division result shall prevail.

[0071] S203. According to the mapping relationship between the attention degree and the weight setting value, determine the weight setting value corresponding to the current attention degree as the weight value.

[0072] The weight setting value is within the weight setting range. The mapping relationship can be a curve diagram of the attention level and the weight setting value or a corresponding table of the attention level and the weight setting value, which can be obtained through experiments or experience.

[0073] Specifically, when the mapping relationship is a curve graph of the degree of attention and the weight setting value, after obtaining the current degree of attention, the curve graph of the degree of attention and the weight setting value can be directly compared to determine the weight setting value on the curve graph corresponding to the current degree of attention as the weight value. Alternatively, when the mapping relationship is a corresponding table of the degree of attention and the weight setting value, after obtaining the current degree of attention, the table can be directly looked up to obtain the weight setting value corresponding to the current degree of attention, and the weight setting value can be determined as the weight value. The weight value is proportional to the degree of attention, that is, the higher the degree of attention, the larger the corresponding weight value.

[0074] For example, Figure 8 A schematic diagram of a monitoring screen structure provided by an embodiment of the present invention, such as Figure 8 As shown, the weight setting range is 0 to 9, the weight value set for the sub-region with a higher degree of attention is 9, the weight value set for the sub-region with a high degree of attention is 3, the weight value set for the sub-region with a low degree of attention is 1, and the weight value set for the sub-region with a relatively low degree of attention is 0.

[0075] S204: Control the monitoring device to capture the monitoring screen in real time, and obtain the sub-movement value of each sub-area in real time.

[0076] S205: Determine a monitoring power level of the monitoring device according to the sub-movement value and the weight value corresponding to each sub-area, and control the monitoring device to operate at the monitoring power level.

[0077] The technical solution of the embodiment of the present invention sets corresponding weight values ​​for each sub-area in the monitoring screen according to the features in the monitoring screen and based on the user's attention to each feature. In this way, the user's attention to each sub-area is numerically quantified through the weight value, so as to improve the accuracy of determining the monitoring power level when the monitoring power level of the monitoring device is subsequently calculated based on the weight value.

[0078] Embodiment 3

[0079] On the basis of the above-mentioned embodiment, the embodiment of the present invention describes the situation of controlling the monitoring device to capture the monitoring picture in real time and obtaining the sub-movement value of each sub-area in real time. Figure 3 A flowchart of a third method for controlling a monitoring device provided by an embodiment of the present invention is shown in FIG. Figure 3 As shown, the control method of the monitoring device includes:

[0080] S301, obtaining a monitoring screen captured by a monitoring device and a weight setting range, and dividing the monitoring screen into a plurality of sub-areas arranged in an array.

[0081] S302: Set a weight value for each sub-area according to the monitoring screen and the weight setting range.

[0082] Among them, the weight value is within the weight setting range.

[0083] S303, control the monitoring device to capture the monitoring screen in real time, and determine whether there is a part of the sub-area in the second monitoring screen that is different from the corresponding part of the sub-area in the first monitoring screen; if so, execute S304; if not, execute S308.

[0084] The first monitoring picture is the monitoring picture of the previous frame acquired by the monitoring device, and the second monitoring picture is the monitoring picture of the next frame acquired by the monitoring device. The dynamic picture is composed of multiple frames of static pictures acquired by the monitoring device within a unit time, that is, the video picture obtained by the user from the monitoring device is a dynamic picture formed by the continuous playback of each frame of static pictures acquired by the monitoring device.

[0085] Specifically, the monitoring device is controlled to capture the monitoring screen in real time so as to obtain the monitoring screen of each frame. By comparing the second monitoring screen of the next frame with the first monitoring screen of the previous frame, when the screen in some sub-areas of the second monitoring screen is different from the screen in the corresponding sub-areas of the first monitoring screen, it is determined that there is movement of people or objects in the area monitored by the monitoring device. When the screen in each sub-area of ​​the second monitoring screen is the same as the screen in each sub-area of ​​the first monitoring screen, it is determined that there is no movement of people or objects in the area monitored by the monitoring device.

[0086] S304: extracting people or objects in sub-regions in the second monitoring picture that are different from some sub-regions in the first monitoring picture.

[0087] Specifically, if there are some sub-areas in the second monitoring screen that are different from the corresponding sub-areas in the first monitoring screen, it means that there are people or objects moving in the area monitored by the monitoring device. On this basis, it is currently impossible to determine whether the person or object is an outsider, or whether the person or object will affect the security of the monitoring area. Therefore, the people or objects in the sub-areas of the second monitoring screen that are different from the sub-areas in the first monitoring screen can be extracted for analysis, so as to determine the power level of the monitoring device according to the analysis results.

[0088] S305, determining whether the people or objects in the sub-areas different from the partial sub-area images in the first monitoring image are all in the person whitelist; if so, executing S306, if not, executing S307.

[0089] Among them, the character whitelist includes the characteristics of specific people, and / or the characteristics of specific objects. The specific people and specific objects will not affect the security of the monitored area, and the specific people and / or specific objects are set according to the actual needs of the user. Exemplarily, the monitoring equipment is installed in a residential house, the specific people may include permanent residents living in the residential house, and the specific objects may include animals such as cats or dogs living in the residential house. It can also be other, which is not specifically limited here. The characteristics of specific people include facial features and height features, etc., and the characteristics of specific objects include animal outlines, etc., which can be set according to actual needs and are not specifically limited here.

[0090] Specifically, the features of the people or objects in the sub-areas different from the partial sub-areas in the first monitoring screen can be compared with the specific people or objects in the person whitelist. If the features of the people or objects in the second monitoring screen that are different all match the features of the specific people or objects in the person whitelist, it means that the people or objects in the sub-areas different from the partial sub-areas in the first monitoring screen all exist in the person whitelist. If the features of the people or objects in the second monitoring screen that are different do not match the features of the specific people or objects in the person whitelist, it means that at least some of the people or objects in the sub-areas different from the partial sub-areas in the first monitoring screen do not belong to the person whitelist.

[0091] S306: Determine the sub-movement value of each sub-region as the second movement value.

[0092] The second movement value may be a fixed value, which may be determined according to actual needs. Optionally, the second movement value may be zero, or other values, which are not specifically limited here.

[0093] Specifically, when the people or objects in the sub-areas that are different from the partial sub-areas in the first monitoring screen are all in the person whitelist, it means that there are no outsiders or foreign objects in the area monitored by the monitoring device, and only the people or objects in the person whitelist are working or living normally in the monitoring area, which has no impact on the security of the monitoring area. At this time, the sub-movement value of each sub-area where the picture has changed and where the picture has not changed can be set to the second movement value, that is, the sub-area where the picture has changed is regarded as not moving. In this way, when a moving person or object appears in the monitoring screen and belongs to the person whitelist, the contribution of the person or object to the sub-movement value can be ignored, preventing the movement of the person or object in the person whitelist from causing the monitoring device to be continuously at a high power level, thereby affecting the service life of the monitoring device.

[0094] S307: Determine the sub-movement value of each sub-region where the person or object not in the person whitelist is located as the first movement value, and determine the sub-movement value of each sub-region where the person or object in the person whitelist is located as the second movement value.

[0095] 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 of each sub-area. Optionally, the value range of the first movement value is A, 0<A≤1. Exemplarily, the first movement value is 1, the second movement value is 0, and it can also be other, which is not specifically limited here. The first movement value can be determined according to the degree of difference between the picture of the next frame in the sub-area and the picture of the previous frame. Exemplarily, the larger the ratio of the area of ​​the picture in the next frame in the sub-area that is different from the picture in the previous frame to the total area of ​​the sub-area, the larger the first movement value, and the ratio of the area of ​​the picture in the next frame in the sub-area that is different from the picture in the previous frame to the total area of ​​the sub-area can also be directly used as the first movement value. The way to determine the first movement value according to the actual movement of each sub-area can also be other, which is not specifically limited here.

[0096] Specifically, if the people or objects in the sub-areas different from the partial sub-areas in the first monitoring screen include people or objects that are not in the person whitelist, it means that a foreign person or foreign object has entered the monitoring area. At this time, the sub-movement value of each sub-area where the person or object in the person whitelist is located can be determined as the same second movement value as the sub-area where the screen has not moved, and the sub-movement value of each sub-area where the person or object that is not in the person whitelist is located can be determined as a first movement value greater than the second movement value, so that the monitoring power level of the monitoring device can be determined later according to the first movement value and the second movement value.

[0097] S308: Determine that the sub-movement values ​​of each sub-region are all the second movement values.

[0098] Specifically, when the images in each sub-area in the second monitoring screen are the same as the corresponding sub-areas in the first monitoring screen, it means that there is no movement of people or objects in the area monitored by the monitoring device. At this time, the sub-movement value of each sub-area can be determined as the second movement value.

[0099] S309: Determine a monitoring power level of the monitoring device according to the sub-movement value and the weight value corresponding to each sub-area, and control the monitoring device to operate at the monitoring power level.

[0100] The technical solution of the embodiment of the present invention is that if the images of each sub-area in the second monitoring screen are the same as the images of each corresponding sub-area in the first monitoring screen, then the sub-movement value of each sub-area is determined to be the second movement value. By setting a character whitelist, when there are images of some sub-areas in the second monitoring screen that are different from the images of some sub-areas in the first monitoring screen, the people or objects in the sub-areas in the second monitoring screen that are different from the images of some sub-areas in the first monitoring screen are extracted, and the extracted people or objects are compared with the people or objects in the character whitelist. If the extracted people or objects all belong to the character whitelist, the sub-movement value of each sub-area is determined to be the second movement value that is the same as the sub-movement value of the sub-area that has not moved; if the extracted people or objects include people or objects that do not belong to the character whitelist, the sub-movement value of each sub-area where the people or objects that do not belong to the character whitelist is determined to be the first movement value, and the sub-movement value of each sub-area where the people or objects that belong to the character whitelist is determined to be the second movement value. In this way, by setting up a whitelist of people, the movement of people or objects in the whitelist of people within the monitoring area will not affect the security of the monitoring area. When a person or object in a sub-area where the picture changes belongs to the whitelist of people, the sub-area where the picture changes will be regarded as if the picture has not changed. When the monitoring power level of the monitoring device is subsequently determined according to the sub-movement value, the accuracy of determining the monitoring power level of the monitoring device can be improved, thereby extending the service life of the monitoring device.

[0102] On the basis of the above-mentioned embodiment, the embodiment of the present invention describes the situation of determining the monitoring power level of the monitoring device according to the sub-movement value and the weight value corresponding to each sub-area. Figure 4 A flowchart of a fourth method for controlling a monitoring device provided by an embodiment of the present invention is shown in FIG. Figure 4 As shown, the control method of the monitoring device includes:

[0103] S401, acquiring a monitoring screen captured by a monitoring device and a weight setting range, and dividing the monitoring screen into a plurality of sub-areas arranged in an array.

[0104] S402: Set a weight value for each sub-area according to the monitoring screen and the weight setting range.

[0105] Among them, the weight value is within the weight setting range.

[0106] S403: Control the monitoring device to capture the monitoring picture in real time, and obtain the sub-movement value of each sub-area in real time.

[0107] S404: Determine the product of the sub-movement value of the sub-region and the weight value as the sub-comprehensive movement value of the sub-region.

[0108] Specifically, the sub-comprehensive movement value is the movement amount after the sub-movement value is enlarged or reduced according to the weight value. Exemplarily, if the sub-movement value of the sub-region is 1, but the weight value of the sub-region is 0, then the sub-comprehensive movement value of the sub-region is 0. If the sub-movement value of the sub-region is 0.8, but the weight value of the sub-region is 1, then the sub-comprehensive movement value of the sub-region is 0.8. If the sub-movement value of the sub-region is 0 and the weight value is 9, then the sub-comprehensive movement value of the sub-region is 0. If the sub-movement value of the sub-region is 1 and the weight value is 3, then the sub-comprehensive movement value of the sub-region is 3.

[0109] S405: Determine the current total movement amount of the monitoring screen according to the sub-comprehensive movement values ​​corresponding to the sub-areas.

[0110] Specifically, the sub-comprehensive movement value of the sub-region can reflect the movement reference amount of the sub-region, and the current total movement amount can reflect the movement reference amount of the monitoring screen. In an optional embodiment, the sum of the sub-comprehensive movement values ​​can be used as the current total movement amount of the monitoring screen, so that the monitoring power level can be determined later according to the current total movement amount.

[0111] It should be noted that a matrix may be used to represent the sub-movement value, weight value, and sub-comprehensive movement value of each sub-region. For example, the monitoring screen is divided into m rows and n columns, and the monitoring screen includes m×n sub-regions. Matrix A is used to represent the sub-movement value of each sub-region in the monitoring screen, matrix B is used to represent the weight value of each sub-region in the monitoring screen, and matrix C is used to represent the sub-comprehensive movement value of each sub-region in the monitoring screen, which are respectively:

[0112]

[0113] Among them, the matrix C is the Hadamard product of the matrix A and the matrix B, that is, C = [a ij b ij ], i∈[1,m], j∈[1,n]. The current total movement amount P of the monitoring screen is the sum of all the values ​​in the matrix C, that is,

[0114] S406: Based on the mapping relationship between the 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.

[0115] Among them, the power level is directly proportional to the total movement. That is, the larger the total movement, the higher the power level. The higher the power level, the higher the monitoring quality of the monitoring equipment. Different power levels correspond to different video resolutions, video frame rates, and audio sampling rates. The mapping relationship can be a curve graph of the total movement and the power level, or a corresponding table of the total movement and the power level, which can be obtained through experiments or experience. Exemplarily, as shown in Table 1, the total movement 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 also include others. For example, at the first power level, the infrared LED power of the monitoring device in the night view is 100% of the rated power; at the second power level, the infrared LED power of the monitoring device in the night view is 80% of the rated power; at the third power level, the infrared LED power of the monitoring device in the night view is 60% of the rated power; at the fourth power level, the infrared LED power of the monitoring device in the night view is 40% of the rated power. The working parameters corresponding to the power level can also be other, which can be set according to actual needs and are not specifically limited here.

[0116] Table 1

[0117]

[0118]

[0119] Specifically, when the mapping relationship is a curve graph of total movement and power level, after obtaining the current total movement, the curve graph of total movement and power level can be directly compared to determine the power level on the curve graph corresponding to the current total movement as the current power level. Alternatively, when the mapping relationship is a corresponding table of total movement and power level, after obtaining the current total movement, the power level corresponding to the current total movement can be directly looked up in the table, and the power level is determined as the monitoring power level. After the monitoring power level is determined, the monitoring device is controlled to operate at the monitoring power level, so that the monitoring device adjusts the current working parameters according to the current total movement, thereby making the monitoring device not need to work at a higher monitoring power level all the time, and reducing the working temperature of the monitoring device. In this way, the monitoring device can adjust the monitoring power level in real time according to the changes in the current screen. When the monitoring device is at a lower monitoring power level, the heat generated at a higher monitoring power level can be released at this stage, and the heat generated by the monitoring device itself can be reduced, thereby reducing the heat generated by the monitoring device as a whole, and extending the service life of the monitoring device.

[0120] The technical solution of the embodiment of the present invention uses the product of the sub-movement value of the sub-region and the weight value as the sub-comprehensive movement value of the sub-region, and then uses the sum of the sub-comprehensive movement values ​​of each sub-region as the current total movement of the monitoring screen. During the total time period of monitoring by the monitoring device, the power level corresponding to the current total movement can be determined as the monitoring power level based on the mapping relationship between the total movement and the power level, so that the monitoring device can adjust the monitoring power level in real time according to the changes in the current screen. When the monitoring device is at a lower monitoring power level, the heat generated at a higher monitoring power level can be released at this stage, and the heat generated by the monitoring device itself can be reduced, thereby reducing the heat generated by the entire monitoring device, avoiding the monitoring device from working under high temperature conditions for a long time, and extending the service life of the monitoring device.

[0121] Embodiment 5

[0122] On the basis of the above-mentioned embodiment, the embodiment of the present invention describes the situation that the monitoring device operates at the monitoring power level, and the monitoring power level is less than the maximum power level of the monitoring device. Figure 5 A flowchart of a fifth method for controlling a monitoring device provided by an embodiment of the present invention is shown in FIG. Figure 5 As shown, the control method of the monitoring device includes:

[0123] S501, acquiring a monitoring screen captured by a monitoring device and a weight setting range, and dividing the monitoring screen into a plurality of sub-areas arranged in an array.

[0124] S502: Set a weight value for each sub-area according to the monitoring screen and the weight setting range.

[0125] Among them, the weight value is within the weight setting range.

[0126] S503: Control the monitoring device to capture the monitoring picture in real time, and obtain the sub-movement value of each sub-area in real time.

[0127] S504: Determine a monitoring power level of the monitoring device according to the sub-movement value and the weight value corresponding to each sub-area, and control the monitoring device to operate at the monitoring power level.

[0128] S505: When the monitoring device operates at a monitoring power level and the monitoring power level is less than a maximum power level of the monitoring device, obtain the sound intensity of the environment in which the monitoring device is located.

[0129] When the monitoring device operates at the highest power level, the heat generated by the monitoring device is relatively high.

[0130] Specifically, when the current monitoring power level of the monitoring device is less than the maximum power level, it means that the total movement of the monitoring screen is small. At this time, the sound intensity of the environment in which the monitoring device is located can be obtained through the sound detection device to judge the situation around the monitoring screen through the sound, so as to adjust the working state of the monitoring device in advance before the person or object that makes the sound enters the monitoring screen, so as to capture the person or object that makes the sound in time and improve the monitoring reliability of the monitoring device. Among them, a sound detection device such as a microphone can be set in the monitoring device to obtain the decibel value of the sound in the environment in which the monitoring device is located.

[0131] S506: Determine whether the sound intensity is greater than a preset intensity; if so, execute S507.

[0132] The preset intensity may be a fixed value and may be set according to actual needs. For example, the preset decibel is 50 db.

[0133] Specifically, when the sound intensity is greater than the preset intensity, it indicates that an abnormal event (a cry for help from a person or an alarm from an alarm) may have occurred in the environment where the monitoring device is located, and the abnormal event has not yet entered the monitoring area of ​​the monitoring device.

[0134] S507, determine whether the sound of the environment in which the monitoring device is located belongs to the sound whitelist; if so, execute S508; if not, execute S509.

[0135] The sound whitelist includes specific sounds, which can be set according to the monitoring environment of the monitoring device. For example, when the monitoring device is set in a home where a cat is raised, the cat's cry can be added to the sound whitelist. When the environment where the monitoring device is located has the sound of a fixed animal (such as the sound of a cicada) in a certain season, the sound of the fixed animal can be added to the sound whitelist.

[0136] Specifically, the characteristics of the sound in the environment where the monitoring device is located can be compared with the sound in the sound whitelist. If the characteristics of the sound in the current environment match those in the sound whitelist, it means that the sound emitted in the current environment belongs to the sound whitelist. If the characteristics of the sound in the current environment do not match those in the sound whitelist, it means that the sound emitted in the current environment does not belong to the sound whitelist. The characteristics of the sound include timbre and frequency.

[0137] S508. Control the monitoring device to operate at the monitoring power level.

[0138] Specifically, if the sound emitted in the current environment belongs to the sound whitelist, it means that no abnormal event has occurred in the environment where the monitoring device is located. At this time, the monitoring device can be controlled to operate at the current monitoring power level.

[0139] S509. Control the monitoring device to operate at the highest power level.

[0140] Specifically, if the sound emitted in the current environment does not belong to the sound whitelist, it means that an abnormal event has occurred in the environment where the monitoring device is located. At this time, the monitoring device can be controlled to operate at the highest power level, so that when the abnormal event enters the monitoring area of ​​the monitoring device, the monitoring device can obtain a clear picture of the abnormal event, which is convenient for subsequent verification.

[0141] According to the technical solution of the embodiment of the present invention, when the current monitoring power level of the monitoring device is less than the maximum power level of the monitoring device, it means that the total movement of the monitoring screen is small. At this time, the sound intensity of the environment in which the monitoring device is located can be obtained through the sound detection device. When the sound intensity is greater than the preset intensity, and the sound belongs to the sound whitelist, it means that no abnormal event has occurred in the environment in which the monitoring device is located. At this time, the monitoring device is controlled to continue to operate at the current monitoring power level. When the sound intensity is greater than the preset intensity, and the sound does not belong to the sound whitelist, it means that an abnormal event has occurred in the environment in which the monitoring device is located. At this time, the monitoring device is controlled to operate at the highest power level, so that when the abnormal event enters the monitoring area of ​​the monitoring device, the monitoring device can obtain a clear picture of the abnormal event, which is convenient for subsequent verification.
