The comprehensive management method of smart parks is to achieve comprehensive, efficient and intelligent management of parks by integrating advanced information technology and digital means.

[0003] In the prior art, for example, Chinese Patent Application CN113642995A discloses a management method and device based on a smart park, which determines the type of the smart park and collects the basic information of the smart park; establishes a visual three-dimensional model of the smart park according to the basic information of the smart park; divides the smart park into several unit areas through the three-dimensional model, and obtains the function information and location information of the several unit areas; determines the positions of different types of intelligent devices already set in the smart park through the three-dimensional model; manages the unit areas corresponding to the intelligent devices through the positions of the intelligent devices, so as to realize the management of the intelligent park by managing at least some of the corresponding unit areas. This method realizes efficient and convenient centralized management, but it is necessary to establish a three-dimensional model, which increases the workload. Another example is Chinese Patent CN116962460B, which discloses a smart park operation management system and method. The intelligent video analysis subsystem includes a plurality of smart light poles arranged in the smart park, and the smart light poles include edge computing devices; the edge computing devices are configured to perform the following video analysis steps: obtain the video data of the camera device; perform target object recognition on the video data, and the target object is a human body; when it is recognized that there is a target object in the video data, use the convolutional neural network algorithm to output the head detection frame, hand detection frame and hand-held object detection frame of the target object; based on the head detection frame and the hand detection frame, output a behavior discrimination result; identify the hand-held object in the hand-held object detection frame to obtain a dangerous object discrimination result of the hand-held object; according to the behavior discrimination result and the dangerous object discrimination result, output an alarm information. This method performs video analysis through the smart light poles in the park, with a large investment, which increases the management cost of the park.

[0004] Therefore, providing a digital-based intelligent management method, platform and storage medium for a park, while reducing the management cost, reducing energy consumption, and improving the management efficiency and security of the smart park, is an urgent problem to be solved.

If the first set temperature is higher than the lower limit value of the first controllable room temperature range, do not operate on the first air-conditioning control panel. If the first set temperature is lower than the lower limit value, set the set temperature of the first air-conditioning control panel to the lower limit value, so that the air-conditioning equipment operates at the temperature of the lower limit value;

[0030] Step 35: Obtain the second set temperature on the first air-conditioning control panel. If the second set temperature is lower than the upper limit value of the first controllable room temperature range, do not operate on the first air-conditioning control panel. If the second set temperature is higher than the upper limit value, set the set temperature of the first air-conditioning control panel to the upper limit value, so that the air-conditioning equipment operates at the temperature of the upper limit value.

[0031] Specifically, the power generation equipment and the power supply equipment are also connected to the energy storage equipment.

[0057] In order to make the purpose, technical solutions and advantages of the present invention more clear and understandable, the following further details the present invention in conjunction with the drawings and embodiments. Obviously, the specific embodiments described herein are only used to explain the present invention, which are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0058] It should be noted that if the description in the embodiments of the present invention involves "first", "second", etc., such descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the fact that those of ordinary skill in the art can implement it. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0059] Figure 1 The figure shows a flowchart of an embodiment of the digital-based intelligent management method for the park provided by the present invention, and the flowchart specifically includes the following steps:

[0060] Provide a video surveillance system, which includes a first judgment module and a video analysis module. The video surveillance system is connected to a video surveillance device. The video surveillance device collects video data of a surveillance area, analyzes the first video data within a first preset time to obtain a picture analysis result and an audio analysis result, generates a first analysis result based on the picture analysis result and the audio analysis result, and sends the first analysis result to the first judgment module. The first judgment module judges whether there is a change in the surveillance area based on the first analysis result. If so, it obtains the first video data from the video surveillance device, and the video analysis module analyzes the first video data.

[0061] The first preset time is set according to the experience of those skilled in the art or according to the actual application scenario, and the embodiments of the present application do not limit this. Exemplarily, the first preset time is 10 seconds, 30 seconds, 1 minute, etc.

[0062] During the daily operation of the park, to ensure the safety of the park, it is necessary to monitor the situation in the park in real time, analyze the video surveillance data to timely discover abnormal personnel, fires and other situations endangering the safety of the park. Real-time monitoring will generate a large amount of video surveillance data. If there are no pedestrians passing through and no abnormal changes occur in certain surveillance areas at certain time points, which is equivalent to a static picture, this section of video data has no analytical significance. If this section of video data is also transmitted to the video surveillance system, it will increase the transmission pressure.

[0063] Specifically, analyzing the first video data within the first preset time to obtain a picture analysis result and an audio analysis result includes:

[0064] Initialize the picture change value to 0, and obtain the base frame stored in the video surveillance device;

[0065] Calculate the inter-frame difference value between the first frame image of the first video data and the base frame. If the inter-frame difference value is greater than or equal to the first preset value, add 1 to the picture change value, then define the first frame image as the base frame, and define the frame image after the first frame image as the first frame image. If the inter-frame difference value is less than the first preset value, directly define the first frame image as the base frame, and define the frame image after the first frame image as the first frame image. Repeat this step. After traversing all the frame images in the first video data, define the picture change value as the picture analysis result;

[0066] Obtain the audio data in the first video data, count the number of audio fluctuations where the sound decibel in the audio data is greater than or equal to the second preset value, and define the number of audio fluctuations as the audio analysis result.

[0067] The first preset value and the second preset value are set according to the experience of those skilled in the art or according to the actual application scenario, and the embodiments of the present application do not limit this.

[0068] When starting to analyze the first video data within the first preset time, the basic frame stored in the video monitoring device is the last frame image of the video data collected at the previous first preset time.

[0069] The inter-frame difference value is the sum of the differences between the pixel values ​​of all corresponding pixels between any two adjacent frames of images. When the inter-frame difference value is greater than or equal to the first preset value, the picture change value is increased by 1. While analyzing the picture of the first video data, the audio of the first video data in the monitoring area is analyzed, and the number of audio fluctuations in the first video data whose sound decibel is greater than or equal to the second preset value is defined as the audio analysis result.

[0070] Specifically, the first analysis result further includes a collection position of the video surveillance device and a collection time of the first video data. The first judgment module judges whether there is a change in the monitoring area based on the first analysis result, including:

[0071] Step 11: Based on the acquisition position and the acquisition time, obtain the picture analysis threshold and the audio analysis threshold corresponding to the first video data.

[0072] Step 12: determine whether the image analysis result is greater than or equal to the image analysis threshold. If so, determine that there is a change in the monitoring area. If not, proceed to step 13.

[0073] Step 13: determine whether the audio analysis result is greater than or equal to the audio analysis threshold. If so, determine that there is a change in the monitoring area.

[0074] Due to the differences in buildings, equipment, external environment, etc. in different monitoring areas, and the different changes in the environment such as lighting at different times, different image analysis thresholds and audio analysis thresholds are set for different monitoring areas in different time periods based on location and time. For example, during non-working hours, the park environment is relatively quiet, and the audio analysis threshold is 0. During working hours, the park environment will be relatively noisy, and the audio analysis threshold is set to 3; different monitoring areas have different equipment noise, vehicle noise, etc., and different audio analysis thresholds are set for different monitoring areas according to the equipment or vehicle conditions in the monitoring area.

[0075] According to an embodiment of the present invention, after the video surveillance device collects video data, it analyzes the picture and audio of the video data, and then sends the analysis result to the video surveillance system. When the video surveillance system determines that there is an abnormality or change in the monitored area, it obtains video data from the video surveillance device, which can reduce the amount of data transmission and alleviate communication pressure.

[0076] Provide a security warning system. The security warning system is connected to a video surveillance system and an electronic identification code collection system. When the video analysis module determines that there is someone in the surveillance area, it obtains the first face image in the surveillance area and obtains the first electronic identification code of the first user in the surveillance area through the electronic identification code collection system. It determines whether the first user is a legitimate person based on the first face image and the first electronic identification code. If not, an alarm prompt is given.

[0077] Specifically, the security warning system includes a user information management module. Determining whether the first user is a legitimate person based on the first face image and the first electronic identification code includes:

[0078] Step 21: Search for the user information management module based on the first electronic identification code, and determine whether the first electronic identification code is located in the user information management module. If it is located, go to step 22; if not, go to step 24. Among them, the user information management module stores the electronic identification codes, face images, and permitted activity areas of each legitimate person.

[0079] Step 22: Obtain the second face image corresponding to the first electronic identification code in the user information management module based on the first electronic identification code, and determine whether the first face image and the second face image are the same person. If so, go to step 23; if not, go to step 24.

[0080] Step 23: Determine whether the first user is located within the permitted activity area corresponding to the first user based on the collection location of the video surveillance device. If not, go to step 24.

[0081] Step 24: Obtain the appearance time of the first user in the surveillance area. When the appearance time exceeds the third preset value, it is determined that the first user is not a legitimate person.

[0082] Before the above step 21, collect the identity information of the user, set an electronic identification code for the user, and set a permitted activity range for each user. Exemplarily, the permitted activity range of employees of Company A is Area 1 and Area 2, and the permitted activity range of management personnel is the entire park.

[0083] The electronic identification code can be the SIM card number, access control card number, work permit number, etc. of the user. A wireless module is set on the access control card or work permit, which can respond to the electronic identification code acquisition request of the electronic identification code collection system.

[0084] According to the technical solution of the present invention, not only can the staff in the park be identified and tracked, but also the personnel who temporarily enter the park from outside the park can be identified and tracked. At the same time, only when the appearance time of the first user in the monitoring area exceeds the third preset value, it is determined that the first user is not a legitimate person, so as to avoid identifying passing personnel as illegal intrusion users, implementing alarm reminders, causing unnecessary trouble, and improving the safety management level of the park.

[0085] Specifically, different warning levels are set for different activity areas based on a preset time period. If the first user is not a legitimate person, the warning level corresponding to the monitoring area is obtained based on the acquisition time of the first video data, and alarm prompts are made based on the warning level.

[0086] Exemplarily, the warning levels of the activity areas are set according to working hours and non-working hours, and different warning levels are set for different activity areas according to the importance of the activity areas.

[0087] Exemplarily, the alarm prompts include sending text message reminders to department managers, relevant users, security personnel, etc., and / or turning on lights in the monitoring area where abnormal personnel appear, and lighting the street lights near the abnormal personnel in color.

[0088] A temperature regulation system is provided, which obtains the number of people in any room at preset time intervals, obtains the first controllable room temperature range corresponding to the number of people based on the operation mode of the air conditioning equipment and the number of people in any room, and regulates the indoor temperature based on the first controllable room temperature range.

[0089] The preset time interval is set according to the experience of those skilled in the art or according to the actual application scenario, and the embodiments of the present application do not limit this.

[0090] In the smart park, the central air conditioning system is used for temperature regulation, and the corresponding temperature regulation range is set according to the number of people indoors, so that each office place adjusts the air conditioning equipment according to its corresponding temperature regulation range. While achieving the goal of a suitable indoor temperature, unnecessary energy waste can be reduced, which helps to improve the intelligence of park management.

[0091] Preferably, before temperature control, a number of people - temperature range table is generated according to the operation mode of the air conditioning equipment. Exemplarily, the number of people - temperature range adjustment table is as follows: in the cold air mode, for 0 - 5 people, the lower temperature limit is 27, and for 6 - 10 people, the lower temperature limit is 26; in the warm air mode, for 0 - 5 people, the upper temperature limit is 27, and for 6 - 10 people, the upper temperature limit is 26.

[0092] Preferably, since the floors, orientations, areas, etc. of each office space are different, the air-conditioning set temperatures required for the indoor temperature to reach a comfortable temperature for the human body are different. Therefore, based on the location, area, etc. of each office space, different number-temperature range tables are set for each office space.

[0093] Specifically, the temperature regulation system is connected to the air-conditioning control panel of each room. The regulation of the indoor temperature based on the first controllable room temperature range includes:

[0094] Step 31: Determine whether the first controllable room temperature range is the same as the second controllable room temperature range in the previous stage. If they are the same, no regulation is performed. If they are different, proceed to Step 32.

[0095] Step 32: Set the first controllable room temperature range as the adjustable range of the air-conditioning equipment in any room and display the first controllable room temperature range on the first air-conditioning control panel in any room.

[0096] Step 33: Determine whether the air-conditioning equipment is in the cold air mode or the warm air mode. If it is in the cold air mode, proceed to Step 34. If it is in the warm air mode, proceed to Step 35.

[0097] Step 34: Obtain the first set temperature on the first air-conditioning control panel. If the first set temperature is higher than the lower limit value of the first controllable room temperature range, do not operate the first air-conditioning control panel. If the first set temperature is lower than the lower limit value, set the set temperature of the first air-conditioning control panel to the lower limit value so that the air-conditioning equipment operates at the temperature of the lower limit value.

[0098] Step 35: Obtain the second set temperature on the first air-conditioning control panel. If the second set temperature is lower than the upper limit value of the first controllable room temperature range, do not operate the first air-conditioning control panel. If the second set temperature is higher than the upper limit value, set the set temperature of the first air-conditioning control panel to the upper limit value so that the air-conditioning equipment operates at the temperature of the upper limit value.

[0099] In the cold air mode, when the set temperature on the air-conditioning panel is lower than the temperature lower limit value, control the air-conditioning equipment to operate at the lower limit value. When the number of indoor people decreases and there is no need for a cooling effect lower than the above lower limit value, raising the operating temperature of the air-conditioning equipment can reduce the energy waste generated by air-conditioning cooling; when the set temperature on the air-conditioning panel is higher than the temperature lower limit value, do not operate the air-conditioning equipment, and before the indoor people operate the air-conditioning, reduce the energy consumption generated by air-conditioning cooling.

[0100] In the warm air mode, when the set temperature on the air conditioner panel is higher than the upper limit value, the air conditioner equipment is controlled to operate according to the upper limit value. When the number of indoor people increases and there is no need for a heating effect higher than the above upper limit value, reducing the operating temperature of the air conditioner equipment can reduce the energy waste generated by the air conditioner heating. When the set temperature on the air conditioner panel is lower than the lower limit value, no operation is performed on the air conditioner equipment, and the energy consumption generated by the air conditioner heating is reduced before the indoor people operate the air conditioner.

[0101] Provide an energy management system. The energy management system is connected to the electricity meters of each electricity user, the power generation equipment in the park, and the power supply equipment of the power supply company, and controls the power supply and collects electricity bills based on the electricity consumption of all electricity users, the power generation of the power generation equipment, and the power supply cost of the power supply company.

[0102] Exemplarily, the power generation equipment is solar photovoltaic power generation, wind power generation, etc.

[0103] With the continuous promotion of the "energy conservation and emission reduction" policy in China, building a photovoltaic power station, a decentralized wind farm, etc. in the park can provide a reliable guarantee for the energy supply of the park while achieving energy conservation, environmental protection and reducing energy costs.

[0104] Specifically, the power generation equipment and the power supply equipment are also connected to the energy storage equipment. The power supply control based on the electricity consumption of all electricity users, the power generation of the power generation equipment, and the power supply cost of the power supply company includes:

[0105] Obtain the predicted values of all influencing factors affecting the power generation of the power generation equipment on the second day at the first preset time of the day, and input all the predicted values into the preset model to obtain the predicted power generation on the second day;

[0106] Predict the expected electricity consumption of any electricity user on the second day at the second preset time of the day, and calculate the total expected electricity consumption of all electricity users on the second day;

[0107] Calculate the sum of the predicted power generation and the electricity storage in the energy storage equipment. If the total expected electricity consumption is greater than the sum of the electricity, calculate the electricity difference between the total expected electricity consumption and the sum of the electricity, and control the energy storage equipment to store electricity based on the electricity difference during the low electricity price stage;

[0108] When supplying power to the electrical equipment in the park on the second day, give priority to using the energy storage equipment and the power generation equipment for power supply.

[0109] The first preset time and the second preset time are set according to the experience of those skilled in the art or according to the actual application scenario, and the embodiments of the present application do not limit this. The first preset time and the second preset time can be the same or different. Exemplarily, the first preset time is 21:00 every day, and the second preset time is 22:00 every day.

[0110] When the power generation of the power generation equipment is greater than the total power consumption of all electricity users, the excess power can be stored in the energy storage equipment. When controlling power supply, if the sum of the predicted power generation and the stored power is less than the predicted total power consumption of the next day, calculate the power difference between the predicted total power consumption and the sum of the power, and store power in the energy storage equipment during the low electricity price stage based on the power difference and the remaining capacity of the energy storage equipment. When supplying power to the electrical equipment in the park the next day, give priority to using the energy storage equipment and the power generation equipment for power supply. If the power is not enough, purchase power from the power supply company. Based on this, the energy cost can be further reduced.

[0111] Specifically, charging electricity fees based on the power consumption of all electricity users, the power generation of the power generation equipment, and the power supply fees of the power supply company includes:

[0112] Based on the total power consumption of all electricity users, the total power generation of the power generation equipment, and the total power supply fees of the power supply equipment within the third preset time, calculate the electricity price per unit EP, and the calculation formula is:

[0113]

[0114] C = α1×PG,

[0115] where PR is the cost profit rate, C is the power generation cost of the total power generation, BFi is the basic usage fee of the i-th electricity user, EB is the total power supply fee, i is a positive integer from 1 to I, I is the total number of electricity users, EC is the total power consumption, α1 is the parameter weight coefficient, and PG is the total power generation;

[0116] Charge electricity fees from all electricity users based on the electricity price per unit.

[0117] The third preset time is set according to the experience of those skilled in the art or according to the actual application scenario, and the embodiments of the present application do not limit this. Exemplarily, the third preset time is one month.

[0118] Preferably, calculate the basic usage fee based on the area of the electricity usage place of each electricity user. Exemplarily, the basic usage fee of the i-th electricity user is β1×Si, where β1 is the parameter weight coefficient and Si is the area of the electricity usage place of the i-th electricity user.

[0119] Since the weather conditions are different in each stage, the power generation of the power generation equipment is different in each stage. Calculate the electricity price per unit based on the total power consumption of all electricity users, the total power generation of the power generation equipment, and the total power supply fees of the power supply equipment. While ensuring the profitability of the power generation equipment owner, give back the benefits to the electricity users and reduce the electricity cost of the electricity users.

[0120] As a preferred technical solution of the present invention, the unit price of electricity consumption is set as a fixed unit price, which is less than the unit price of electricity of the power supply company. Based on the fixed unit price, the total electricity consumption of all electricity users, the total power supply cost of the power supply equipment, and the basic usage fee of each electricity user, the income of the power generation equipment owner is calculated.
