Description

Technical Field

[0001] This invention relates to the field of camera device technology, and more particularly to a camera device based on clean energy hybrid power generation. Background Technology

[0002] As core equipment in fields such as security monitoring, environmental monitoring, and traffic management, video surveillance devices directly determine the working efficiency and application value of related systems through their stable operation and flexible monitoring capabilities. They play an irreplaceable role in ensuring public safety, improving management accuracy, and assisting in decision-making. With the continuous upgrading of society's demand for security and environmental awareness, monitoring scenarios have gradually extended from urban core areas to remote outdoor areas, such as mountain ecological protection areas, suburban traffic routes, and field construction sites. The monitoring needs in these areas have placed higher demands on the performance of video surveillance devices.

[0003] However, existing camera devices based on clean energy hybrid power generation are difficult to use because some areas are far from the city's power grid and it is difficult to achieve convenient access to the mains power. Monitoring tasks usually require the equipment to run 24 hours a day, making it difficult to ensure that the monitoring process is uninterrupted, resulting in the inability to capture various dynamic information in the area in a timely manner.

[0004] Therefore, the above-mentioned technical problems need to be addressed. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a camera device based on clean energy composite power generation.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a camera device based on clean energy composite power generation, comprising a base plate and four rectangular vertical fixing holes that penetrate the base plate. A column is vertically fixed to the middle of the upper part of the base plate. A fixing mechanism is installed on the upper end of the column. A support frame is fixed to the fixing mechanism. A positioning mechanism is assembled on the support frame. A connecting column is fixed to the lower end of the column at the upper end of the support frame. A rotating mechanism is installed above one end of each connecting column by bolts.

[0007] The camera device's control box contains an intelligent control component, which includes a data acquisition module, an analysis module, and an execution module.

[0008] The data acquisition module collects power generation and power consumption data and transmits the collected data to the analysis module.

[0009] The analysis module receives and preprocesses the data from the acquisition module, compares the changes in power generation and consumption before and after the adjustment, and determines whether the adjustment is feasible. If it is not feasible, it analyzes the changes in power generation and consumption during the day and night separately, marks the periods when power generation is less than power consumption, analyzes them according to individual acquisition periods, and narrows down the adjustment range according to the comparison results of power generation and consumption. If the total power consumption is still not met after the adjustment, a power outage is taken, and the power outage measure is transmitted to the execution module.

[0010] The execution module receives signals from the analysis module and performs corresponding operations.

[0011] Preferably, when the analysis module performs data preprocessing, it identifies and removes outliers from multiple data sets collected at the same time, specifically including:

[0012] K1: Calculate the mean and standard deviation of the corresponding data and set the data fluctuation range;

[0013] K2: Compare the collected data with the fluctuation range, and mark data that are outside the range as outliers;

[0014] K3: When the number of outliers exceeds the threshold, the data is judged to be abnormal and re-detected; when the number of outliers does not exceed the threshold, the outliers are removed and the mean of the remaining data is calculated as valid data.

[0015] Preferably, the steps for the analysis module to perform power analysis are as follows:

[0016] S1: Compare the total power generation and total power consumption during the day and night to determine whether to implement the adjustment strategy;

[0017] S2: If the total power generation is insufficient, analyze the changes in power generation and power consumption during the day and night separately, and mark the periods when power generation is greater than power consumption; for unmarked periods, analyze power generation and power consumption according to a single data collection period, and remove the periods when power generation is less than power consumption.

[0018] S3: Filter continuous feasible time periods, determine the angle range of motion, and use the initial angle and the termination angle as the angle range of motion for intelligent adjustment.

[0019] Preferably, the analysis module performs the residual current analysis in the following steps:

[0020] M1: Based on the posterior remaining power at the previous moment, the power generation and power consumption at the current moment, calculate the prior remaining power at the current moment, and calculate the posterior remaining power at the current moment.

[0021] M2: When the predicted remaining power is lower than the first threshold, a power warning signal is generated and transmitted to the execution module; when the predicted remaining power is lower than the second threshold for multiple consecutive times, a power outage preparation signal is generated and transmitted to the execution module.

[0022] Preferably, the rotating mechanism includes a rotating seat bolted to a connecting column. The rotating seat has a cavity inside. A positioning plate is fixedly connected to one side of the cavity. A worm gear is rotatably mounted between the positioning plates. A micro servo motor is mounted on one side of the positioning plate. The output end of the micro servo motor passes through the positioning plate and is coaxially fixed to one end of the worm gear. A worm wheel is rotatably mounted on one side of the worm gear in the middle of the cavity. The worm gear and the worm wheel mesh with each other. A rotating column is fixedly connected above the worm wheel. The rotating column extends vertically upward through the rotating seat and is hinged to the camera.

[0023] Preferably, the fixing mechanism includes a connecting block sleeved on the column, and an arc-shaped fixing block is installed at the same horizontal position on the other end of the connecting block. The arc-shaped fixing block and the connecting block are connected and fixed by hexagonal socket head cap screws. The connecting block has fixing holes that are opened opposite each other. A limit block is slidably installed in the fixing hole. A first telescopic spring is installed between the limit block and the fixing hole.

[0024] Preferably, the positioning mechanism includes telescopic holes that are opened on both sides of the support frame, a positioning block is movably installed in the telescopic hole, and a second telescopic spring is installed between the positioning block and the inner wall of the telescopic hole.

[0025] Preferably, a fixing rod is vertically fixed to the middle of the upper end of the column, and a horizontal axis wind turbine is installed on the upper end of the fixing rod by bolts. A support plate is provided at the lower end of the support frame, and a photovoltaic panel is placed obliquely on the support plate.

[0026] Compared with the prior art, the beneficial effects of the present invention are:

[0027] 1. By combining a horizontal axis wind turbine with photovoltaic panels, it is easy to utilize both wind and solar energy for combined power generation, improving the stability and sustainability of energy acquisition. This enables the uninterrupted power supply to the camera device. Furthermore, the use of connecting blocks, arc-shaped fixing blocks, and support brackets facilitates the secure installation of photovoltaic panels and other power generation components on the device, improving the installation reliability of the equipment in different environments. This allows for the stable integration of the power generation system and the camera device, ultimately solving the problem of the camera device being unable to operate continuously for 24 hours and capture dynamic information of the area in a timely manner.

[0028] 2. By analyzing the power generation during the day and night, the system distinguishes between "high-efficiency power generation periods" and "low-efficiency power generation periods." During the day, when the photovoltaic panels are highly efficient, priority is given to ensuring high-energy-consuming functions such as the camera rotation mechanism. At night, when the wind power generation is inefficient, the system focuses on core monitoring functions to avoid energy waste caused by fixed-mode control. For unmarked periods, by eliminating data collection periods where "power generation < intelligent adjustment power consumption + period-based power consumption," continuous feasible periods are selected, and the angle range is determined. This ensures that the photovoltaic panels / wind turbines are adjusted only within the "effective angle range," avoiding meaningless angle adjustments and further balancing the gap between power generation and power consumption.

[0041] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0042] Example 1: See Figures 1 to 9 The camera device based on clean energy hybrid power generation of this invention includes a base plate 1 and four rectangular vertical fixing holes penetrating the base plate 1. A column 2 is vertically fixed to the upper center of the base plate 1. A fixing mechanism is installed on the upper end of the column 2, and a support frame 5 is fixed to the fixing mechanism. A positioning mechanism is mounted on the support frame 5, and a connecting column is fixed to the lower end of the column 2 at the upper end of the support frame 5. A rotating mechanism is bolted to the upper end of each connecting column. The four rectangular vertical fixing holes in the base plate 1 facilitate the installation and fixing of the entire camera device based on clean energy hybrid power generation. A fixing rod 6 is vertically fixed to the upper center of the column 2. A horizontal axis wind turbine 7 is bolted to the upper end of the fixing rod 6. The vertical connection between the upper center of the column 2 and the fixing rod 6, and the bolted connection between the upper end of the fixing rod 6 and the horizontal axis wind turbine 7, facilitate the stable installation of the horizontal axis wind turbine 7. The system utilizes wind energy for power generation, with the horizontal axis wind turbine model 7 being SH-A2000. The rotating mechanism includes a rotating seat 11 bolted to a connecting column. The rotating seat 11 has an internal cavity, with a positioning plate 10 fixedly connected to one side of the cavity. A worm gear 14 is rotatably mounted between the positioning plates 10, and a micro servo motor 15 is mounted on one side of the positioning plate 10. The output end of the micro servo motor 15 passes through the positioning plate 10 and is coaxially fixed to one end of the worm gear 14. A worm wheel 13 is rotatably mounted on one side of the worm gear 14 in the middle of the cavity, and the worm gear 14 and the worm wheel 13 mesh with each other. A rotating column 12 is fixedly connected above the worm wheel 13. The rotating column 12 extends vertically upward through the rotating seat 11 and is hinged to the camera 8. The hinged connection between the rotating column 12 and the camera 8 facilitates the adjustment of the camera 8's angle. The camera 8 is model MS-669SRT-IPX-4K.

[0043] In this invention, the fixing mechanism includes a connecting block 4 sleeved on the column 2, and an arc-shaped fixing block 3 installed at the same horizontal position on the other end of the connecting block 4. The arc-shaped fixing block 3 and the connecting block 4 are connected and fixed by internal hex bolts. The connecting block 4 has fixing holes that are opposite to each other. A limit block 16 is slidably installed in the fixing hole. A first telescopic spring 17 is installed between the limit block 16 and the fixing hole. The connection between the column 2 and the connecting block 4 facilitates the position adjustment of the connecting block 4 on the column 2. The positioning mechanism includes telescopic holes that are opposite to each other on both sides of the support frame 5. A positioning block 18 is movably installed in the telescopic hole. The positioning block 18 and the telescopic hole are connected by telescopic holes. A second telescopic spring 19 is installed between the inner walls of the contraction hole. Through the telescopic holes on both sides of the support frame 5 and the movable installation of the positioning block 18, and the installation of the second telescopic spring 19 between the positioning block 18 and the inner wall of the telescopic hole, the elastic action of the second telescopic spring 19 is used to make the positioning block 18 extend and retract, thereby positioning the relevant components. A support plate is provided at the lower end of the support frame 5, and a photovoltaic panel 9 is placed obliquely on the support plate. Through the oblique placement of the support plate at the lower end of the support frame 5 and the photovoltaic panel 9, the support plate can support the photovoltaic panel 9. At the same time, the oblique placement makes it easier for the photovoltaic panel 9 to receive sunlight better and improve the light energy utilization efficiency.

[0044] Working Principle: In use, the base plate 1 is first laid flat at the installation position. Expansion bolts are driven into the four rectangular vertical fixing holes in the base plate 1 to ensure complete contact and fixation between the base plate 1 and the bottom surface. Then, the connecting block 4 is fitted onto the column 2 at a distance of 2-5 meters from the bottom surface. The arc-shaped fixing block 3 is connected and fixed to the connecting block 4 using hexagonal socket head cap screws. Simultaneously, the first telescopic spring 17 in the fixing hole of the connecting block 4 pushes the limiting block 16 towards the column 2, ensuring a tight fit between the limiting block 16 and the column 2, thereby enhancing the stability of the fixing mechanism. Next, the photovoltaic panel 9 is placed at an angle on the support plate at the lower end of the support frame 5. The second telescopic spring 19 in the telescopic holes on both sides of the support frame 5 causes the positioning block 18 to retract, thus fixing the photovoltaic panel 9 and preventing it from sliding. Finally, the fixing rod 6 is welded to the middle of the upper end of the column 2, and then bolts are used to connect the horizontal axis wind turbine... The generator 7 is installed on the upper end of the fixed rod 6, with the generator blades facing the wind direction. At the same time, the output wires of the photovoltaic panel 9 and the horizontal axis wind turbine 7 are connected to the energy storage battery and the inverter through the column 2. The output end of the inverter is connected to the power interface of the camera 8 and the micro servo motor 15, ensuring that the circuit connection is correct and that there is no reverse polarity. During the operation of the camera 8, if rotation adjustment is required, the micro servo motor 15 in the rotation mechanism is started. Its output end will pass through the positioning plate 10 and drive the worm gear 14 to rotate between the positioning plates 10. Since the worm gear 14 meshes with the worm wheel 13 in the middle of the cavity, it will drive the rotating column 12 above the worm wheel 13 to rotate around the center. The rotating column 12 vertically upward passes through the rotating seat 11 and is hinged and fixed to the camera 8. Therefore, it can drive the camera 8 to rotate one revolution in the horizontal direction to complete the angle adjustment to meet the detection requirements.

[0045] Example 2: Unlike Example 1, a movable structure is provided between the support plate and the photovoltaic panel 9, so that the photovoltaic panel 9 can rotate according to the solar altitude angle; a movable structure is also provided at the position of the horizontal axis wind turbine 7, so that the generating blades can automatically align with the wind direction;

[0046] See Figure 10 The camera device's control box contains an intelligent control component, which includes a data acquisition module, an analysis module, and an execution module.

[0047] The data acquisition module collects power generation and power consumption data and transmits the collected data to the analysis module.

[0048] The analysis module receives and preprocesses the data from the acquisition module, compares the changes in power generation and consumption before and after the adjustment, and determines whether the adjustment is feasible. If it is not feasible, it analyzes the changes in power generation and consumption during the day and night separately, marks the periods when power generation is less than power consumption, analyzes them according to individual acquisition periods, and narrows down the adjustment range according to the comparison results of power generation and consumption. If the total power consumption is still not met after the adjustment, a power outage is taken, and the power outage measure is transmitted to the execution module.

[0049] The collected data was sorted according to the collection time, and corresponding items collected at the same time were sorted. averaging the data and standard deviation The calculation, and the mean obtained from the calculation. and standard deviation Collect data fluctuation range for corresponding items The system is configured to compare the collected data for a given item with its fluctuation range, mark data outside the fluctuation range as outliers, and record the number of outliers. ,like If the collected data is abnormal, the data will be re-tested; if If outliers are removed, the mean of the remaining corresponding test data after outlier removal is calculated. The calculation, and the mean obtained from the calculation. As the corresponding data detected at the corresponding time;

[0050] Re-examine the corresponding data; if the comparison result is still negative... If the problem is detected, it is determined that the acquisition device is malfunctioning, an equipment warning signal is generated, and the equipment warning signal is transmitted to the execution module.

[0051] After receiving the device warning signal, the execution module controls the buzzer module of the intelligent control component to sound an alarm and displays "Data Acquisition Device Malfunction" on the control box display screen, so that staff can perform timely maintenance on the device.

[0052] Acquire historical data, statistically analyze power generation and consumption data within a set time period from the current point in time, and calculate the average daily total power generation. Total power consumption ,like If so, an adjustment signal is generated and transmitted to the execution module;

[0053] After receiving the adjustment signal, the execution module controls the photovoltaic panel 9 to rotate to follow the angle of the sun during the daytime, and controls the horizontal axis wind turbine 7 to adjust its angle to follow the wind direction during the nighttime. The data acquisition module then collects the total power generation detected during the daytime and nighttime periods after the adjustment. , The data is acquired and then passed to the analysis module; if If the adjustment measures are deemed feasible, the adjustment strategy will be implemented. This involves recording the daily power consumption for intelligent adjustment; conversely, recording the power consumption during the day and night separately, and calculating the difference in total power generation before and after the adjustment for the corresponding time periods. If the difference in total power generation for the corresponding time periods is greater than... If the adjustment measures for the corresponding time period are deemed effective, then that time period will be marked. 120% of the power consumption during the corresponding period Intelligent power consumption adjustment for corresponding time periods;

[0054] For power generation data in a single acquisition period within the unmarked period. and power consumption Sort by data collection period, and analyze the power consumption data for intelligent adjustment within a single data collection period. Power consumption data intelligently adjusted during this period The total number of individual data collection periods within this period; for The data collection periods are removed, and the remaining data collection periods are sorted. The number of intervals between adjacent data collection periods is recorded. The determination is a continuous time period. The initial angle and the termination angle corresponding to the continuous time period are obtained. The initial angle and the termination angle are used as the range of angle activity for intelligent adjustment within the unmarked time period.

[0055] Total power generation after adjustment Total power consumption The comparison, if If the range is not specified, then range limitation signal one is generated and transmitted to the execution module; otherwise, the same method is used to analyze the adjustment angle within the marked time period. The data collection period is removed, and the initial and ending angles of the continuous period are used as the range of intelligent adjustment angles within the marked period to generate a range limit signal two, which is then transmitted to the execution module.

[0056] After receiving the first range limitation signal, the execution module controls the active structure to adjust the angle of the unmarked time period according to the angle activity range of the unmarked time period analyzed by the analysis module; after receiving the second range limitation signal, the execution module controls the active structure to limit the angle adjustment range of the two time periods respectively.

[0057] The power consumption structures of the camera device are classified and sorted in the following order: "core monitoring functions of the camera (image acquisition, encoding, basic transmission), energy storage system and energy conversion components (inverter, battery management module), moving structure, and auxiliary display and warning components (display screen, buzzer)". When the power generation is less than the power consumption, the power supply to the auxiliary display and warning components is disconnected first. Power is only supplied when needed, and the power supply to the moving structure is disconnected after the corresponding period of adjustment is completed, so as to further achieve the effect of energy saving.

[0058] set up Prior remaining power at time , The state transition matrix ( , Battery self-discharge rate, during the day ,night ), for The a posteriori remaining battery power at time 1. and They are respectively Total power generation and total power consumption at any given time. This is process noise; therefore Prior error covariance at time , for The posterior error covariance at time 1. Let be the process noise covariance, where is due to For scalar, ;

[0059] Kalman gain , Here is the observation matrix, and the observation noise covariance is... ;because Simplifying the Kalman gain formula, we get ;but Post-hoc remaining battery power at time , To observe noise; Posterior error covariance at time 1 ;

[0060] If prediction The system generates a "battery warning signal," and the execution module prioritizes disconnecting power to the auxiliary display and warning components, retaining only the core camera functions. This refers to the rated capacity of the energy storage battery; if predictions are made for three consecutive time periods... If "the adjusted total power generation still does not meet the total power consumption," then a "power outage preparation signal" is generated 10 minutes in advance, and the execution module saves data such as the current camera angle and monitoring video to avoid data loss due to a sudden power outage; if the predicted daytime period is... The execution module can relax the frequency adjustment of the activity structure and use excess power to improve the monitoring coverage.

[0061] Meanwhile, the instability of single-energy power supply makes long-term monitoring difficult under energy consumption constraints. Therefore, a highly efficient monitoring system combining solar and wind power with intelligent dynamic scheduling is needed. This system combines the complementary power supply capabilities of solar and wind power with intelligent dynamic task scheduling algorithms to design a highly efficient monitoring system. Through solar photovoltaic panels and wind power generation devices mounted on support poles, a continuous and stable supply of new energy is achieved, effectively addressing the uncertainty of power supply during cloudy or windless days. The system applies a dynamic task scheduling algorithm to intelligently adjust equipment power consumption based on actual environmental conditions. By setting and adjusting the intensity of supplementary lighting, the system optimizes the image acquisition effect, ensuring image quality under limited energy conditions. Furthermore, multi-task optimization scheduling incorporating the Hungarian algorithm balances system performance and energy consumption across different dimensions. The Hungarian algorithm addresses the allocation of multiple tasks. This comprehensive technology increases the camera's battery life under extreme conditions by over 50%, achieving long-term, blind-spot-free monitoring coverage.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
