Description

Technical Field

[0001] This invention belongs to the field of camera power supply technology, specifically a camera power supply system. Background Technology

[0002] As living standards gradually improve, people's demand for security monitoring is also increasing. For example, people need to monitor their rural homes and villages after migrating to cities for work; monitoring crops is also necessary during agricultural planting. Over time, the demand for monitoring is growing stronger. Currently, the main monitoring methods are wired monitoring, or a small portion of wireless monitoring. Wireless monitoring mostly uses dry cell batteries as the power source for cameras, which is convenient for use in urban homes. However, these two methods are inconvenient for users who cannot easily replace batteries or for monitoring locations in remote areas. Therefore, to supplement the existing power supply methods for surveillance cameras, this invention provides a camera power supply system. Summary of the Invention

[0003] To address the problems of the above solutions, the present invention provides a camera power supply system.

[0004] The objective of this invention can be achieved through the following technical solutions:

[0005] A camera power supply system includes an installation module and a power supply analysis module;

[0006] The installation module is used to guide the installation of the camera and power supply equipment;

[0007] Furthermore, the installation module's working method includes:

[0008] A power supply method database is established. Users fill in the environmental data of the monitoring area according to the user information statistics template. After the data is filled in, the user information statistics table is uploaded. The corresponding power supply combination method is matched from the power supply method database based on the user information statistics table and marked as a candidate method. The candidate methods are then filtered to obtain the corresponding target method. The installation personnel carry the camera and power supply equipment corresponding to the target combination method to the destination to install the equipment.

[0009] Furthermore, the methods for screening the candidate methods include:

[0010] The system retrieves the equipment cost and monitoring effect corresponding to each candidate power supply method from the power supply method library, identifies the expected cost and monitoring expectations filled in by users in the user information statistics table, conducts corresponding evaluations to obtain the corresponding cost priority value and monitoring priority value, calculates the screening value of each candidate method according to the screening value formula, and determines the corresponding target method based on the screening value.

[0011] Further, the screening value formula is: QC = b1×JKZ + b2×CBZ, where CBZ is the cost priority value; JKZ is the monitoring priority value; b1 and b2 are both proportionality coefficients, and the value range is 0 < b1 ≤ 1, 0 < b2 ≤ 1.

[0012] Further, the method for determining the target mode according to the screening value includes:

[0013] Sort the obtained screening values in descending order to obtain the first sequence, remove the screening values in the first sequence that are not greater than the threshold X1 to obtain the second sequence, and select the first N candidate modes corresponding to the screening values in the second sequence as the target mode, where N is a positive integer.

[0014] The power supply analysis module is used to perform power supply analysis during the operation of the camera, obtain energy storage data, and determine whether the power supply during the planned duration meets the use of the camera based on the energy storage data and the power consumption data of the camera. When it is determined that the power supply meets the use of the camera, no corresponding operation is performed; when it is determined that the power supply cannot meet the use of the camera, a power supply control plan is set according to the current energy storage data, and the power supply control of the camera is performed according to the set power supply control plan.

[0015] Further, the method for setting the power supply control plan includes:

[0016] Match the corresponding initial time period sequence table according to the monitoring purpose, set the minimum power supply duration for each time period in the initial time period sequence table, generate several initial plans and the corresponding regenerated power and energy efficiency safety values for each initial plan according to the initial time period sequence table, the minimum power supply duration for each time period, and the energy storage data, and select one of the initial plans as the power supply control plan according to the regenerated power and energy efficiency safety values corresponding to each initial plan table.

[0017] Further, the method for screening the initial plan includes:

[0018] Mark the energy efficiency safety value and the regenerated power as NAZ and ZSL respectively, calculate the plan value of each initial plan according to the plan value formula, and select the initial plan with the highest plan value as the power supply control plan.

[0019] Further, the plan value formula is: QA = b3×NAZ + b4×β×ZSL, where b3 and b4 are both proportionality coefficients, and the value range is 0 < b1 ≤ 1, 0 < b2 ≤ 1; β is the unit conversion coefficient.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] By cooperating with the installation module and the power supply analysis module, intelligent power supply control for wireless monitoring is achieved. The installation module enables intelligent installation of monitoring equipment, meeting the power supply needs of cameras as much as possible without connecting to the mains power. Appropriate solar panels and batteries are selected according to the actual environmental conditions to ensure power supply circulation. At the same time, when collecting on-site environmental data, user information statistics templates are set to collect data, which facilitates users to collect environmental data statistics and ensures that comprehensive environmental data is collected.

Obviously, the drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0023] Figure 1 This is a block diagram illustrating the principle of the present invention. Detailed Implementation

[0024] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0025] like Figure 1 As shown, a camera power supply system includes an installation module and a power supply analysis module;

[0026] The installation module is used to install solar panels, batteries, and cameras according to the actual monitoring area. Because the specific power supply solutions applicable vary in different regions and are affected by local climate, sunlight, and other environmental factors, the optimal power supply solution adopted varies depending on user costs in different environments. This includes different combinations of solar panel models, sizes, and battery models and capacities. The specific setup method is as follows:

[0027] Edit the currently available power supply combinations, set them according to the actual situation of the merchants, and set the corresponding applicable scope for each power supply combination, indicating which environmental conditions the power supply combination can be applied to, including the equipment cost of the power supply combination, the monitoring effect that can be achieved, etc. After integrating the power supply combinations, applicable scope and equipment cost, a power supply method library is established.

[0028] Set up a user information statistics template, which is used for users to input corresponding monitoring area environmental data, such as location, sunshine conditions, surrounding environmental conditions, expected investment costs, monitoring expectations to be achieved, etc. The environmental data can also be supplemented by filling in pictures, videos, etc. By setting a unified information statistics template, it is convenient for users to conduct information statistics and subsequent corresponding data recognition. Users fill in environmental data according to the user information statistics template and upload the completed user information statistics template; Identify the user information statistics template uploaded by the user, and match the power supply combination mode that meets the environmental requirements from the power supply mode library according to the environmental data filled in the user information statistics template. The environment is used as the matching item for matching, and cost and monitoring effect are not used as the basis for this matching; Corresponding power supply combination mode matching can be achieved according to the corresponding scope of application;

[0029] Mark the matched power supply combination mode as a candidate mode, and evaluate the cost priority value and monitoring priority value of each candidate mode relative to the user's expected cost and monitoring expectations. The evaluation is mainly based on the degree of proximity to the expected cost and monitoring expectations. Specifically, a corresponding expected evaluation model is established based on the CNN network or DNN network, and a corresponding training set is established and trained manually. After successful training, the expected evaluation model analyzes the user's expected cost, monitoring expectations, and the costs and monitoring effects corresponding to each candidate mode, and outputs the corresponding cost priority value and monitoring priority value; Since the neural network is an existing technology in this field, the specific establishment and training processes are not described in detail in this invention;

[0030] Mark the cost priority value and monitoring priority value as CBZ and JKZ respectively, calculate the corresponding screening value according to the screening value formula QC = b1×JKZ + b2×CBZ, where b1 and b2 are both proportionality coefficients, and the value range is 0 < b1 ≤ 1, 0 < b2 ≤ 1. Sort the obtained screening values in descending order to obtain the first sequence. Eliminate the screening values in the first sequence that are not greater than the threshold X1 to obtain the second sequence. Select the candidate modes corresponding to the first N screening values in the second sequence as the target modes, where N is a positive integer, which is used to avoid the problem that only one power supply combination device is not suitable for the actual situation when arriving at the actual area;

[0031] The installer carries the combination device corresponding to the target combination mode to the destination to install the camera and power supply device.

[0032] By setting up the installation module, intelligent installation of monitoring equipment can be achieved, meeting the power supply needs of the cameras as much as possible without connecting to the mains power. Appropriate solar panels and batteries can be selected according to the actual environmental conditions to ensure power supply cycle. At the same time, when collecting environmental data in the field, data can be collected by setting up user information statistics templates, which facilitates users to collect environmental data statistics and ensures that comprehensive environmental data is collected.

[0033] The power supply analysis module is used to analyze the power supply during camera operation and to make reasonable power consumption plans based on actual power generation. When the generated and stored power cannot fully meet the monitoring needs, selective monitoring is performed according to the importance of monitoring at different times of the day to ensure the monitoring needs of important periods and maximize the monitoring effect. Because it is difficult to use mains power in environments such as the wild, the power supply mainly relies on solar power generation. If it can be combined with mains power for joint power supply, the above planning is not necessary; power planning can be done based on power generation, usage, and storage. If there is excess power connected to the grid, and solar power generation is insufficient, mains power is used. Existing mains power combined with solar power technology can achieve corresponding power supply management. However, for cameras that only use solar power, the power supply analysis is as follows:

[0034] Real-time acquisition of battery capacity and solar power generation data is integrated into energy storage data. This data, combined with camera power consumption data, is used to assess whether the current energy storage capacity meets power demand for the next period. A planned duration is manually set to evaluate whether the energy storage data within that duration meets power demand. This assessment can be conducted by setting warning thresholds, etc. If the power demand is met, no action is taken; if it is not met, power planning is required.

[0035] Based on the monitoring objectives, a corresponding initial time period sequence table is matched. In detail, the monitoring objectives under the current circumstances are obtained, and based on these objectives, a corresponding initial time period sequence table is manually set to indicate the monitoring importance of each time period during the day under these objectives. Based on the energy storage data and the power consumption data of the cameras, the remaining power supply time is analyzed, and the remaining power supply time is allocated according to the initial time period sequence table to obtain a corresponding power supply control scheme. The power supply control of the cameras is then implemented according to the obtained power supply control scheme.

[0036] Among them, the allocation of the remaining power supply duration according to the initial time period sequence table is a dynamic analysis process. The power supply changes in each time period will lead to changes in the available power supply duration, and then a suitable power supply plan is analyzed. Set the minimum power supply duration for each time period, that is, ensure the minimum time required for monitoring in that time period. Under the condition of ensuring the minimum power supply duration for each time period, generate different power supply plans for each time period according to the initial time period sequence table. That is, on the premise of the minimum power supply duration for each time period, distribute the excess power according to the importance of the time periods in various different amounts of power, that is, ensure that the amount of distributed power is sorted according to the order of each time period in the initial time period sequence table, and evaluate the power generated as surplus due to incomplete power supply in some time periods according to this plan. It may still be in the power generation process and is regarded as regenerated power. The regenerated power will be redistributed into the power supply plan and cycle continuously until the distribution of the regenerated power is completed to form an initial plan. However, the first regenerated power will be used as the evaluation basis for the subsequent initial plan; specifically, a corresponding power supply plan model can be established based on the CNN network or DNN network, and a corresponding training set is established through artificial means for training. After successful training, the power supply plan model analyzes the initial time period sequence table, the minimum power supply duration for each time period, and the energy storage data to obtain several initial plans and the regenerated power and energy efficiency safety values corresponding to each initial plan. The regenerated power refers to the first cycle; the energy efficiency safety value is evaluated according to the power supply duration distribution in each time period of the initial plan to evaluate the safety of this method, and then the corresponding energy efficiency safety value is assigned;

[0037] Mark the energy efficiency safety value and the regenerated power as NAZ and ZSL respectively, and calculate the plan value of each initial plan according to the plan value formula QA = b3×NAZ + b4×β×ZSL, where b3 and b4 are both proportionality coefficients, and the value range is 0 < b1 ≤ 1, 0 < b2 ≤ 1; β is the unit conversion coefficient, which is specifically set through discussion by the expert group; select the initial plan with the highest plan value as the power supply control plan.

[0038] The above formulas are all calculated by removing the dimension and taking their numerical values. The formula is obtained by collecting a large amount of data for software simulation to get a formula closest to the actual situation. The preset parameters and preset thresholds in the formula are set by those skilled in the art according to the actual situation or a large amount of data.

[0039] The above embodiments are only used to illustrate the technical method of the present invention and not to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical method of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical method of the present invention.
