Description

Technical Field

[0001] This application relates to the field of security, and more specifically, to a low-power monitoring method, device, electronic device, and composite monitoring system. Background Technology

[0002] In field operations, the deployment of monitoring systems often faces the problem of insufficient conventional power lines and network communication facilities. Therefore, solar energy is commonly used as the primary energy source. The monitoring device converts solar energy into electrical energy through solar panels, and stores and distributes it through energy storage circuits to support 24 / 7 operation.

[0003] However, solar power supply has many inherent limitations. Sunlight intensity is significantly affected by day-night cycles, weather changes, seasonal fluctuations, and geographical location, leading to large fluctuations in output power. Simultaneously, solar panels are affected by the degradation and aging of electronic components, environmental dust pollution, and ambient temperature, increasing the uncertainty of output power. In this context, excessive energy consumption will shorten operating time, while excessive energy saving may sacrifice monitoring capabilities. Therefore, equipment power consumption management is directly related to whether it can operate continuously and stably.

[0004] To overcome the limitations of solar power, the technology employs an architecture that combines panoramic cameras and PTZ cameras to ensure effective monitoring performance under limited energy conditions. The panoramic camera operates at a low frame rate or intermittently, continuously sensing a large area of ​​the scene and maintaining low power consumption when no anomalies are detected. Once a potential target is detected, the PTZ camera is triggered to activate high-resolution acquisition and optical zoom functions for precise tracking and secondary verification. This avoids the enormous energy consumption associated with running multiple high-definition video streams continuously, concentrating resources on the critical event response phase, thereby significantly reducing average power consumption while ensuring monitoring effectiveness.

[0005] Current mainstream energy-saving strategies are mostly based on the remaining battery power as the basis for regulation. For example, when the battery power is below a certain threshold, the battery enters a sleep or frequency reduction state to extend standby time. Although such methods can control energy consumption to a certain extent, their regulation logic is limited to the power parameter itself and does not consider the effectiveness of monitoring or environmental adaptability. Summary of the Invention

[0006] To overcome at least one deficiency in the prior art, this application provides a low-power monitoring method, apparatus, electronic device, and composite monitoring system, including: In a first aspect, this application provides a low-power monitoring method applied to a pan-tilt camera in a composite monitoring system, wherein the composite monitoring system further includes a panoramic camera communicatively connected to the pan-tilt camera and sharing the same power supply, and the method includes: Obtain the current ambient light intensity and the remaining power of the power supply; If the ambient light intensity is less than the PTZ light threshold, the monitoring power consumption of the PTZ camera under the remaining power is obtained. Under the condition that the ambient light intensity is less than the panoramic light threshold, the panoramic camera only provides the communication relay function between the PTZ camera and the cloud platform. The PTZ light threshold is less than the panoramic light threshold. The first sleep cycle of the PTZ camera is determined based on the monitored power consumption and the remaining power. Periodic hibernation occurs according to the first hibernation cycle.

[0007] Secondly, this application provides a low-power monitoring device for use in a PTZ camera within a composite monitoring system. The composite monitoring system further includes a panoramic camera communicatively connected to the PTZ camera and sharing the same power supply. The device comprises: The remaining power module is used to obtain the current ambient light intensity and the remaining power of the power supply; The power consumption prediction module is used to obtain the monitoring power consumption of the gimbal camera under the remaining power if the ambient light intensity is less than the gimbal illumination threshold. The panoramic camera only provides the communication relay function between the gimbal camera and the cloud platform when the ambient light intensity is less than the panoramic illumination threshold. The gimbal illumination threshold is less than the panoramic illumination threshold. The sleep control module is used to determine the first sleep cycle of the PTZ camera based on the monitored power consumption and the remaining power; and to perform periodic sleep according to the first sleep cycle.

[0008] Thirdly, this application provides a gimbal camera, which includes a processor and a memory. The memory stores a computer program, which, when executed by the processor, implements the low-power monitoring method.

[0009] Fourthly, this application also provides a composite monitoring system, which includes the aforementioned pan-tilt camera and panoramic camera; The panoramic camera and the gimbal camera are communicatively connected and share the same power supply.

[0010] Compared with the prior art, this application has the following beneficial effects: The low-power monitoring method, apparatus, electronic device, and composite monitoring system provided in this application include a PTZ camera and a panoramic camera communicatively connected to the PTZ camera and sharing the same power supply. The PTZ camera acquires the current ambient light intensity and the remaining power of the power supply. If the ambient light intensity is less than the PTZ light threshold, the monitoring power consumption of the PTZ camera under the remaining power is acquired. When the ambient light intensity is lower than the panoramic light threshold, the panoramic camera only provides communication relay functionality between the PTZ camera and the cloud platform; the PTZ light threshold is lower than the panoramic light threshold. Based on the monitoring power consumption and remaining power, a first sleep cycle for the PTZ camera is determined. Periodic sleep is then performed according to the first sleep cycle. Thus, by dynamically adjusting the sleep strategy based on lighting conditions and energy consumption levels, meaningless power consumption is avoided while maintaining responsiveness to critical events, thereby achieving a balance between monitoring effectiveness and energy utilization.

Detailed Implementation

[0013] To make the objectives, technical solutions, and advantages of the embodiments of this application (hereinafter referred to as "the embodiments") clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0014] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0015] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0016] In the description of this application, it should be noted that the terms "first," "second," "third," etc., are used only for distinguishing descriptions and should not be construed as indicating or implying relative importance. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0017] Based on the above statement, as introduced in the background technology, most of the current mainstream energy-saving strategies are based on setting a graded monitoring mode for the remaining battery power. Although such methods can control energy consumption to a certain extent, their regulation logic is limited to the power parameters themselves and does not consider the monitoring effectiveness and environmental adaptability.

[0018] Specifically, research revealed that in current solar-powered monitoring systems, a typical energy-saving strategy is to divide the monitoring mode based on the remaining battery power. For example, when the battery power is above 60%, the device runs at full frame rate and performs complete image analysis; when the battery power is between 20% and 60%, the video acquisition frame rate is reduced or some computing functions are turned off; when the battery power is below 20%, only the communication module remains online, while all other sensing and processing units enter a sleep state.

[0019] However, while the aforementioned method of switching modes based on battery thresholds can delay battery depletion, it lacks dynamic adaptation to the actual monitoring environment. Specifically, in low-light scenarios, even if the battery level is still high (e.g., 75%), the ambient light is insufficient for the camera to acquire clear images. Performing full image analysis in this situation would likely yield ineffective results. This means a significant amount of power is wasted on ineffective data acquisition and computation, without providing corresponding monitoring value. Conversely, simply putting the camera into sleep mode in insufficient light could lead to missing crucial anomalies.

[0020] It should be noted that the defects in the solutions in the prior art are the result of practice and careful research. Therefore, the discovery process of the above problems and the solutions proposed by the embodiments of this application in the following text should be regarded as contributions to this application in the process of invention and creation, and should not be understood as technical content known to those skilled in the art.

[0021] Based on the discovery of the above-mentioned technical problems, this embodiment provides a low-power monitoring method applied to a PTZ camera in a composite monitoring system. The composite monitoring system also includes a panoramic camera that is communicatively connected to the PTZ camera and shares the same power supply.

[0022] For example, such as Figure 1 As shown, this composite monitoring system includes a PTZ camera and a panoramic camera, which are communicatively connected and share the same power source (solar panel). In this architecture, the panoramic camera acts as the panoramic communication and control base, interacting with the cloud platform through an embedded communication device. It also manages and controls the energy storage circuit downwards and issues PTZ control commands to the PTZ camera upwards. Under the scheduling of the panoramic camera, the PTZ camera performs flexible and dynamic acquisition of the monitored scene and completes local storage of real-time scene data. The solar panel converts solar radiation energy into electrical energy through the photoelectric effect. The energy storage circuit receives, stores, and distributes this electrical energy, powering both the panoramic camera and the PTZ camera.

[0023] The study also found that in existing monitoring devices, when using a single-core processor architecture, a single core needs to simultaneously handle multiple tasks such as multi-view panoramic acquisition and stitching, PTZ control, AI image processing, and data communication. This results in the overall load being concentrated on a single core, leading to problems such as excessive CPU utilization and response latency. In contrast, when using a multi-core isomorphic symmetric multi-processing (SMP) architecture, each processor core runs under the same operating system, resulting in a high degree of resource sharing and difficulty in achieving functional isolation. The master core and slave cores are often running synchronously and cannot independently control power consumption, causing the remaining modules to continue operating at high power consumption even when some functions are paused.

[0024] Therefore, in this embodiment, the processor of the gimbal camera has a single-core or multi-core homogeneous structure; The panoramic camera's processor has a multi-core heterogeneous architecture, including a master core and slave cores. When the ambient light intensity is lower than the panoramic light threshold, the panoramic camera disables the slave cores and uses the master core to provide communication relay functions between the gimbal camera and the cloud platform.

[0025] For example, such as Figure 2 As shown, the PTZ camera and panoramic camera in the composite monitoring system employ different processor architectures to adapt to their functional requirements and power consumption constraints. The PTZ camera's processor is a single-core or multi-core homogeneous structure, meaning that each processor core has the same permissions within the same System-on-Chip (SoC) chip, sharing memory, input / output interfaces, and interrupt resources, and running the same operating system, which uniformly manages task scheduling and resource allocation. Tasks running on it include image acquisition, artificial intelligence (AI) image processing, zooming, USB communication, AI intelligent analysis, storage, always-on video (AOV) low-power control, and video encoding.

[0026] The panoramic camera's processor adopts a multi-core heterogeneous architecture, including a main core and slave cores located within the same SoC chip, but each running independently on different computing platforms and operating systems, with different permission configurations and exclusive access to allocated hardware resources. The main core, as the main control central processing unit, is responsible for running the user's main program and handling comprehensive tasks such as wireless communication, USB communication, energy storage management, storage control, gimbal control command issuance, AOV low-power control, and AI intelligent analysis.

[0027] The slave core is dedicated to media processing, including computationally intensive media tasks such as multi-view sensor data acquisition, AI image processing, multi-view image stitching, and video encoding. Communication between the master and slave cores is achieved through a shared memory area and synchronization mechanism, ensuring real-time and consistent data exchange. The panoramic camera interacts with the gimbal camera via a virtual network interface card (NIC) using the Remote Network Driver Interface Specification (RNDIS) and can also wake up the gimbal camera using external signals.

[0028] based on Figure 1 as well as Figure 2 The system architecture, such as Figure 3 As shown, the low-power monitoring method provided in this embodiment includes: S1: Obtain the current ambient light intensity and the remaining power of the power supply.

[0029] S2, if the ambient light intensity is less than the PTZ light threshold, then obtain the monitoring power consumption of the PTZ camera with the remaining power.

[0030] Among them, when the ambient light intensity is lower than the panoramic light threshold, the panoramic camera only provides the communication relay function between the gimbal camera and the cloud platform, and the gimbal light threshold is lower than the panoramic light threshold.

[0031] S3 determines the first sleep cycle of the PTZ camera based on the monitored power consumption and remaining power.

[0032] S4, performs periodic hibernation according to the first hibernation cycle.

[0033] In this way, by dynamically adjusting the hibernation strategy in combination with lighting conditions and energy consumption levels, meaningless power consumption can be avoided while maintaining the ability to respond to critical events, thereby achieving a balance between monitoring effectiveness and energy utilization.

[0034] To make the solution provided in this embodiment clearer, the steps of the method provided in this embodiment are described in detail below. However, it should be understood that the operations in the flowchart may not be implemented in sequence, and steps without logical contextual relationships may be reversed in order or implemented simultaneously. Furthermore, those skilled in the art, guided by the content of this application, may add one or more other operations to the flowchart, or remove one or more operations from the flowchart. See also... Figure 3 The method includes: S1: Obtain the current ambient light intensity and the remaining power of the power supply.

[0035] In this embodiment, the ambient light intensity is calculated in real time by image sensors mounted on the panoramic camera and gimbal camera, which collect scene data and combine it with an automatic exposure algorithm or a dedicated light-sensing module. This calculation is used to determine whether the current imaging environment meets the minimum illumination requirements for effective video capture and AI analysis. The remaining power supply comes from the energy storage circuit of the power supply used by the composite monitoring system.

[0036] Based on the descriptions of ambient light intensity and remaining battery power in the above embodiments, we will continue with... Figure 3 Step S2 will be explained below: S2, if the ambient light intensity is less than the PTZ light threshold, then obtain the monitoring power consumption of the PTZ camera with the remaining power.

[0037] Among them, when the ambient light intensity is lower than the panoramic light threshold, the panoramic camera only provides the communication relay function between the gimbal camera and the cloud platform, and the gimbal light threshold is lower than the panoramic light threshold.

[0038] It should be understood that the panoramic illumination threshold and the gimbal illumination threshold are determined based on the imaging performance of their respective cameras and the AI ​​analysis algorithms, and are used to determine whether the panoramic camera and the gimbal camera have the environmental conditions to perform effective video analysis.

[0039] Specifically, the panoramic illumination threshold refers to the minimum ambient light level required for a panoramic camera to maintain a preset standard of recognition accuracy when running its AI intelligent analysis module. This threshold is obtained through actual testing, where the panoramic camera collects a large amount of sample data under different lighting conditions, runs algorithms such as target detection and feature extraction, and outputs the results. Compared with the true value The comparison is performed to calculate the recognition accuracy. The ambient light intensity that satisfies the following formula can be used as the panoramic lighting threshold. :

[0040] In the formula, the output result Compared with the true value When they are the same, the difference between the two is 0. This indicates the number of experiments. The panoramic illumination threshold is determined accordingly. Because panoramic cameras use starlight-level cameras, their light-sensing capabilities are relatively limited. When the ambient light intensity is below the panoramic light threshold, image noise increases significantly, leading to stitching distortion and a higher AI misjudgment rate.

[0041] The gimbal illumination threshold refers to the minimum ambient light required for the gimbal camera to maintain an algorithm recognition accuracy of at least 99.99% when operating its local AI intelligent analysis function. This threshold is also calibrated based on measured data, using the same method as the panoramic camera. However, because it employs a super-starlight-level camera module, it possesses stronger low-light imaging capabilities, enabling it to output clear images even in extremely low-light environments. Therefore, under the same test conditions, its lower limit of illumination for consistently maintaining high-precision recognition is significantly lower, corresponding to a lower gimbal illumination threshold. It is also less than the panoramic illumination threshold, which means it satisfies... .

[0042] because When the ambient light intensity is less than the gimbal's illumination threshold, it means that even the gimbal camera is approaching its imaging limit. At this point, it can enter a deep power-saving mode, requiring the monitoring power consumption of the gimbal camera with its remaining power to determine the subsequent sleep cycle. Simultaneously, if the ambient light intensity is lower than the panoramic illumination threshold, the panoramic camera stops operating from the slave core, retaining only the master core to maintain the wireless communication link. This transforms the master core into a dedicated communication relay node serving the gimbal camera, ensuring that even in extremely low-light scenarios, alarm information generated by the gimbal can still be reported to the cloud platform via this link.

[0043] It should be noted that the recognition accuracy of the above algorithm of no less than 99.99% is only an example provided in this embodiment. In actual implementation, it can be adapted.

[0044] Based on the above explanation of ambient light thresholds and gimbal light thresholds, it should be understood that in insufficient lighting conditions, the gimbal camera only experiences reduced recognition accuracy, not necessarily rendering it unusable. Therefore, to reduce the probability of missing critical abnormal events, the gimbal camera cannot remain in sleep mode indefinitely when the ambient light intensity is below the gimbal light threshold; instead, it needs to periodically enter sleep mode to recognize the acquired images in the awakened state. The specific heavy recognition strategy adopted depends on the remaining battery power. In view of this, this embodiment provides the following optional implementation methods for step S2: S2-1 determines the target monitoring mode of the PTZ camera in the wake-up state from a variety of preset monitoring modes based on the remaining battery power.

[0045] S2-2, based on the target monitoring mode, obtain the monitoring power consumption of the PTZ camera with remaining battery power.

[0046] The above steps can be understood as follows: the monitoring power consumption of the PTZ camera is related to its current monitoring mode, and the determination of the monitoring mode depends on the real-time status of the remaining power. Therefore, in this embodiment, the remaining power is divided into three preset energy ranges, and different monitoring modes are set accordingly. Specifically, when the energy is less than 20%, it enters a low-energy monitoring mode; when the energy is between 20% and 60%, it enters a medium-energy monitoring mode; and when the energy is greater than 60%, it enters a high-energy monitoring mode. In each mode, the PTZ camera operates in AOV low-power control mode, but the method of recognizing the acquired images in the wake-up state is different.

[0047] The so-called AOV low-power control method refers to a method where, after each wake-up, the gimbal camera only acquires one or more images for recognition, and then returns to sleep mode after recognition is complete. For example, such as... Figure 4 As shown, after the set sleep cycle ends, the CPU core is powered on, and the device exits the Suspend to RAM (STR) mode. Then, it captures a frame of image via the camera and performs AI image optimization. Next, the AI-optimized image undergoes DSP processing and AI intelligent analysis. If an abnormal target is detected, an alarm is reported and the data is stored; if no abnormality is detected, the data is temporarily stored in RAM. After processing is complete, the CPU core immediately powers off and re-enters STR mode until the next wake-up. This significantly reduces power consumption while maintaining basic monitoring capabilities, making it suitable for solar or battery-powered scenarios.

[0048] In low-energy monitoring mode, the PTZ camera periodically acquires single-frame images and performs lightweight AI intelligent analysis to identify whether there are any warning targets. It maintains only the minimum monitoring capability and continues to hibernate when no abnormal events are detected.

[0049] In medium-energy monitoring mode, the PTZ camera has a stronger response capability. Therefore, once a potential abnormal target is identified through AI intelligent analysis, the secondary evidence collection logic at the software level is activated. The authenticity of the target is judged by combining historical data or contextual information. Once the risk is confirmed, an alarm message is immediately reported. After the task is completed, it continues to hibernate.

[0050] In high-energy monitoring mode, the PTZ camera can use full monitoring functions. Therefore, when the AI ​​intelligent analysis identifies an abnormal target, it will activate the zoom lens to optically focus on the abnormal target and perform high-precision feature extraction and secondary verification through AI intelligent analysis to ensure the accuracy of the alarm. After the evidence collection is completed, if the target disappears or the preset warning duration limit is reached, it will continue to hibernate.

[0051] Thus, with varying remaining energy levels, the gimbal camera adopts different monitoring modes while in wake-up mode, ensuring a relatively balanced number of image acquisitions and recognitions at different energy levels.

[0052] Based on the monitoring power consumption of the gimbal camera with the current remaining battery power in the above embodiments, the following will continue to... Figure 3 Step S3 will be explained below: S3 determines the first sleep cycle of the PTZ camera based on the monitored power consumption and remaining power.

[0053] In this embodiment, in order to achieve the same relatively balanced number of image acquisitions and recognitions under different energy levels, the following optional implementation methods for step S3 are provided: S3-1 uses the ratio between remaining power and power consumption as the base period; S3-2, by adjusting the base period through a regulating factor, the dormancy period is obtained.

[0054] The adjustment factors include a first adjustment factor and a second adjustment factor. The first adjustment factor is a normalized parameter of the remaining power, which is inversely correlated with the remaining power. The second adjustment factor is a preset weight of the remaining power, which is inversely correlated with the remaining power.

[0055] Specifically, the gimbal camera in the... The sleep-wake cycle used in each energy range It is determined by three parts, namely the current remaining energy storage capacity. The power consumption of the target monitoring mode adopted by the PTZ camera And two first regulating factors associated with this energy range. Second regulatory factor The corresponding expression is:

[0056] In the formula, the remaining stored energy Reflects the total amount of energy available to the system. The ratio of the two values ​​represents the energy consumption per unit time of the gimbal camera under typical low-power operation. This represents the theoretically sustainable operating time without considering other control factors, serving as a baseline period. However, it should be understood that while the baseline period, obtained by comparing the remaining power supply to the monitored power consumption, reflects the theoretically maximum operating time under the current power consumption, using it directly as the sleep period means that redundant energy cannot be reserved, making it difficult to adapt to complex and ever-changing environments.

[0057] Therefore, based on the baseline period, the gimbal camera adjusts the first adjustment factor. Second regulatory factor Adjust the base period. Both factors are for the [missing information - likely a specific period or timeframe]. Each energy range is preset and is inversely correlated with the current remaining power. Specifically, during the high power phase, the two adjustment factors are set to smaller values, and the base cycle is moderately compressed to avoid excessive wake-up due to sufficient power, which would cause unnecessary energy consumption accumulation. During the medium to low power phase, especially when it is close to 20%, the two adjustment factors increase rapidly, significantly extending the sleep cycle, thereby greatly reducing the average power consumption and extending the overall working time of the device.

[0058] S4, performs periodic hibernation according to the first hibernation cycle.

[0059] Thus, when the ambient light intensity is below the PTZ's light threshold, the panoramic camera enters a low-power mode, serving only as a relay between the PTZ camera and the cloud platform. The PTZ camera then determines the target monitoring mode in its wake-up state based on its remaining battery power, and uses this to determine its sleep cycle. After each sleep cycle, the image is identified according to the target monitoring mode. In this way, by dynamically adjusting the sleep strategy based on lighting conditions and energy consumption levels, meaningless power consumption is avoided while maintaining the ability to respond to critical events, thereby achieving a balance between monitoring effectiveness and energy utilization.

[0060] The above embodiments describe a monitoring method when the light intensity is lower than the PTZ light threshold, such as... Figure 5 As shown, this embodiment also provides an implementation method when the light intensity is greater than or equal to the gimbal lighting threshold and less than the panoramic lighting threshold, including: S5. If the ambient light intensity is greater than or equal to the PTZ light threshold and less than the panoramic light threshold, then determine the second sleep cycle of the PTZ camera and the target monitoring mode in the wake-up state based on the remaining power.

[0061] S6, performs periodic hibernation according to the second hibernation cycle.

[0062] This can be understood as follows: when the ambient light intensity is greater than or equal to the PTZ light threshold but less than the panoramic light threshold, the PTZ camera in the composite monitoring system determines its second sleep cycle based on the remaining power of its power supply, and periodically switches between sleep and wake-up states according to this second sleep cycle. During this process, the panoramic camera, because the lighting conditions it relies on have not yet met the requirements for normal operation (i.e., the ambient light intensity is lower than its own set panoramic light threshold), cannot perform panoramic image acquisition and intelligent analysis tasks. It only maintains the operation of the main core to keep the communication link with the cloud platform connected, while shutting down the slave cores and related media processing modules, thus entering a low-power standby state. The PTZ camera, on the other hand, has a lower illumination adaptability and can independently undertake monitoring tasks within this lighting range.

[0063] During the execution of the above steps, the operating mode of the gimbal camera depends on the remaining power level of the power supply, which in turn affects the specific value of the second sleep cycle. In specific implementation, when the remaining power level is less than 20%, the gimbal camera operates in AOV low-power control mode based on the second sleep cycle. This third sleep cycle can be 1 hour. After each wake-up, the gimbal camera adopts the following target monitoring mode: it acquires single-frame image data, performs feature analysis and target recognition on the frame data through the AI ​​intelligent analysis module to determine whether a warning target exists; if a warning target is identified, relevant information is immediately reported; if no target is identified, the original sleep-wake cycle remains unchanged, and the camera continues to sleep until the next wake-up time arrives.

[0064] When the remaining power level is between 20% and 60%, the gimbal camera operates in AOV low-power control mode based on a second sleep cycle, which can be 5 seconds. After the gimbal camera wakes up periodically, the target monitoring mode adopted is as follows: image data is collected and feature recognition is performed by the AI ​​intelligent analysis module; if a warning target is detected, the software logic further determines whether it constitutes a real threat, and if confirmed, a warning message is reported; if the target disappears or the preset duration limit is reached, the camera returns to the original 5-second sleep cycle and continues to sleep.

[0065] In high-energy operating mode with a remaining power of over 60%, the gimbal camera operates using AOV low-power control based on a second sleep cycle, which can be 1 second. Each time the gimbal camera wakes up, the target monitoring mode it adopts is as follows: image acquisition and target recognition performed by the AI ​​intelligent analysis module; once a warning target is detected, the zoom lens is activated to focus on the target at close range and conduct secondary evidence analysis; after confirming an anomaly, a warning message is reported; if the target disappears or the termination conditions are met, monitoring resumes according to the 1-second sleep-wake cycle.

[0066] The above embodiments describe a monitoring method when the light intensity is greater than or equal to the PTZ light threshold but less than the panoramic light threshold, such as... Figure 6 As shown, this embodiment also provides an implementation method when the light intensity is greater than or equal to the panoramic lighting threshold and the remaining power is greater than the energy-saving threshold, including: S7. If the light intensity is greater than or equal to the panoramic light threshold and the remaining power is greater than the energy-saving threshold, then the system will enter periodic sleep mode according to the preset third sleep cycle.

[0067] S8, during its periodic sleep period of the third sleep cycle, receives and responds to the target tracking command from the panoramic camera to track abnormal targets detected by the panoramic camera.

[0068] S9, if the tracking of an abnormal target detected by the panoramic camera reaches the stop condition, then the periodic sleep cycle continues in the third sleep cycle.

[0069] This can be understood as follows: when the ambient light intensity is greater than or equal to the panoramic light threshold, it indicates that the current lighting conditions have met the basic requirements for the panoramic camera to normally acquire images and perform intelligent analysis. At the same time, if the remaining power of the power supply is greater than the energy-saving threshold, it is determined that there is an energy foundation to start the high-efficiency collaborative monitoring mode. At this time, the PTZ camera enters a periodic sleep state with the third sleep cycle as the interval.

[0070] During the above steps, before receiving a target tracking command, the gimbal camera operates in AOV low-power control mode based on the third sleep cycle, which can be 1 second. In this state, the gimbal camera only wakes up periodically to maintain basic functions and does not continuously execute full-frame-rate video acquisition and processing tasks, thereby effectively reducing overall power consumption while ensuring rapid response capabilities. At the same time, the panoramic camera operates at different performance levels depending on its energy operating mode: when the remaining power is between 20% and 60%, the panoramic camera operates in medium power mode, with the core operating at reduced frequency. The multi-view sensor acquires image data at a reduced frame rate and synthesizes the images from various sources into a panoramic view. Then, the image quality is optimized, and panoramic AI intelligent analysis is performed based on the reduced-frame-rate panoramic data to detect the presence of abnormal targets in real time.

[0071] When the remaining power of the power supply is greater than 60%, the panoramic camera works in high power mode, running at full frame rate from the core. The multi-view sensor acquires images at full frame rate, and simultaneously performs AI image processing and intelligent analysis on the panoramic scene, thereby improving the accuracy and timeliness of target recognition.

[0072] During this process, once the panoramic camera detects an abnormal target in the panoramic view, it generates a target tracking command and sends it to the gimbal camera via USB RNDIS (Remote Network Driver Interface Specification, RNDIS) virtual network card communication. After the current sleep cycle ends and the gimbal camera wakes up, it immediately receives and responds to the target tracking command, exits AOV mode, and enters normal operating mode. Subsequently, the panoramic camera maps the position information of the warning target in the panoramic coordinate system and converts it into gimbal control parameters to instruct the gimbal camera to rotate to the target's location. The gimbal camera uses its zoom lens to optically magnify the target area and uses its built-in AI intelligent analysis algorithm to perform secondary forensic analysis of the local image to confirm whether the target characteristics constitute a real threat. If an abnormal target is confirmed, a data packet containing timestamps, location information, and image evidence is directly reported to the cloud platform; if the target disappears or continuous monitoring reaches the preset time limit without re-identification, the tracking task is considered complete, and the gimbal camera re-enters AOV mode, resuming its periodic sleep state based on the third sleep cycle.
