Technical Field

[0001] The present invention relates to the technical field of electricity consumption monitoring, and in particular to a method and system for monitoring and controlling safe electricity consumption in a smart property building. Background Art

[0002] In many residential buildings in communities, due to the lack of real-time monitoring and intelligent management of electrical equipment, it is difficult for property managers to respond quickly and accurately to equipment failures, safety incidents and other issues, thereby reducing overall management efficiency and increasing the incidence of equipment failures and safety hazards. Therefore, it is necessary to conduct intelligent and safe electricity monitoring and control for property buildings.

[0003] The prior art, such as the invention patent application with announcement number: CN117424769A, discloses an intelligent building energy-saving management system and method based on the Internet of Things. The system includes: upon request from the intelligent terminal device, the real-time status data of the energy-consuming device can be sent and visualized on the front-end page of the intelligent terminal device, and the working status and energy consumption value of each energy-consuming device can be viewed and monitored. Through the remote management mode, remote monitoring and control of many building equipment can be achieved, and an intuitive energy consumption reference value can be provided to enable users to consciously adjust their own electricity consumption behavior, reduce building management costs and improve safety through automation.

[0004] Prior art, such as the invention patent application with announcement number: CN111402346A, discloses a BIM-based smart building system and its management method, the system of which includes: this invention can detect the relevant data of the entire building by setting corresponding functional modules, and control the relevant devices in the building, effectively ensuring the safety of the entire building and achieving timeliness in solving problems; at the same time, this invention can automatically control the temperature and humidity of the entire building, reducing the burden on staff and improving work efficiency.

[0005] It can be seen from the above scheme that the current building safety electricity monitoring and control method lacks certain attention to the safety analysis and processing of the power well room based on the monitoring data of the power well room. In the building, there is usually an power well room on each floor. During the use of the power well room, due to improper maintenance of the environment in the power well room or accumulation of debris, the cable damage problem in the power well room is easy to occur. The voltage and current values ​​of the power well room are often large. Once the cable damage problem occurs, short circuit problems are likely to occur, and even fires will occur, thereby reducing the safety of electricity use in the building. At the same time, there is a lack of attention to whether there is a problem of private wiring in intelligent monitoring. Private wiring can easily lead to fires, thereby increasing the fire rate in buildings. Summary of the invention

[0006] The purpose of the present invention is to provide a method and system for monitoring and controlling safe electricity use in smart property buildings, which solves the problems existing in the background technology.

[0007] In order to solve the above technical problems, the present invention adopts the following technical solutions: The first aspect of the present invention provides a method for monitoring and controlling safe electricity use in a smart property building, including: Step 1.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] Reference Figure 1 As shown, the first aspect of the present invention provides a method for monitoring and controlling safe electricity use in a smart property building, comprising: Step 1. Safety analysis of the building distribution box: obtaining the total input voltage value of each distribution box belonging to the building at the current monitoring time point, the surface charge number of each monitoring point, and the voltage value of each output end, screening each abnormally grounded distribution box and each distribution box to be analyzed belonging to the building, dispatching an intelligent robot to detect each distribution box to be analyzed belonging to the building, obtaining the surface image of each cable of each distribution box to be analyzed belonging to the building, and screening each cable damaged distribution box and each line aging distribution box belonging to the building.

[0024] In a specific embodiment, the total input voltage value of each distribution box belonging to the building, the surface charge number of each monitoring point, and the voltage value of each output end at the current monitoring time point are obtained, and the specific acquisition method is: the total input voltage value of each distribution box belonging to the building is obtained by a voltage sensor installed at the input end of each distribution box belonging to the building, the surface charge number is obtained by a charge sensor installed at each monitoring point of each distribution box belonging to the building, and the voltage value of each output end of each distribution box belonging to the building is obtained by a voltage sensor installed at the output end of each distribution box belonging to the building.

[0025] In a specific embodiment, the surface image of each cable of each distribution box to be analyzed in the building is obtained by a specific method: the surface image of each cable of each distribution box to be analyzed in the building is obtained by a camera carried by the intelligent robot.

[0026] In a specific embodiment of the present invention, the abnormally grounded distribution boxes and the distribution boxes to be analyzed belonging to the screening building are screened by a specific screening method: based on the total input voltage value of each distribution box belonging to the building and the surface charge number of each monitoring point at the current monitoring time point, the abnormally grounded distribution boxes and the normal outer shell distribution boxes belonging to the building are analyzed.

[0027] According to the voltage values ​​of each output terminal of each distribution box belonging to the building, the voltage values ​​of each output terminal of the normal distribution boxes in each shell of the building are extracted, and the output voltage abnormality coefficients of the normal distribution boxes in each shell of the building are analyzed.

[0028] The output voltage abnormality coefficient threshold is obtained from the local database. If the output voltage abnormality coefficient of a normal distribution box in a building is greater than the output voltage abnormality coefficient threshold, the normal distribution box in the building is used as the distribution box to be analyzed, thereby screening the distribution boxes to be analyzed in the building.

[0029] It should be noted that the local database is used to store the output voltage abnormality coefficient threshold, the upper limit of the allowable surface charge number of each monitoring point of the distribution box in each total input voltage value interval, the shell live hazard coefficient threshold, the rated voltage value of the output end of the distribution box, the initial surface image of each cable of each distribution box to be analyzed in the building, the image similarity threshold, the allowable storage items in the electric wells on each floor of the building, the dust hazard coefficient threshold, the space volume value of the electric wells on each floor of the building, the allowable dust concentration value of the electric wells in each humidity value interval, each temperature value interval and each space volume value interval, and each allowable connection item of the external wires.

[0030] In a specific embodiment of the present invention, the specific analysis method of analyzing each abnormal grounding distribution box and each normal shell distribution box belonging to the building is as follows: obtaining the upper limit value of the allowable surface charge number of each monitoring point of the distribution box under each total input voltage value interval from the local database, and mapping the upper limit value of the allowable surface charge number of each monitoring point of each distribution box belonging to the building according to the total input voltage value of each distribution box belonging to the building at the current monitoring time point. , where x represents the number of each distribution box, , y is a positive integer greater than 2, i represents the number of each monitoring point, , j is a positive integer greater than 2.

[0031] According to the surface charge number of each monitoring point of each distribution box in the building , calculate the surface charge imbalance of each distribution box in the building , where j represents the number of monitoring points, and calculates the leakage hazard coefficient of each monitoring point of each distribution box in the building .

[0032] Calculate the live shell hazard coefficient of each distribution box in the building .

[0033] The threshold value of the shell live hazard coefficient is obtained from the local database. If the shell live hazard coefficient of a distribution box belonging to the building is greater than the threshold value of the shell live hazard coefficient, the distribution box will be regarded as an abnormal grounding distribution box. Otherwise, the distribution box will be regarded as a normal shell distribution box, thereby screening the abnormal grounding distribution boxes and normal shell distribution boxes belonging to the building.

[0034] In a specific embodiment of the present invention, the output voltage abnormality coefficient of the normal distribution box of each housing belonging to the building is analyzed, and the specific analysis method is: obtaining the rated voltage value B of the output end of the distribution box from the local database.

[0035] According to the voltage value of each output terminal of the normal distribution box of each housing of the building , where n represents the normal distribution box of each enclosure, , m is a positive integer greater than 2, p represents the number of each output terminal, , q is a positive integer greater than 2, calculate the output voltage abnormality coefficient of the normal distribution box of each shell in the building .

[0036] In a specific embodiment of the present invention, the screening of damaged cable distribution boxes and aging line distribution boxes belonging to a building, the specific screening method is: obtaining the initial surface image of each cable of each distribution box to be analyzed belonging to the building from the local database, and comparing the surface image of each cable of each distribution box to be analyzed belonging to the building with the initial surface image for image similarity, so as to obtain the image similarity of each cable of each distribution box to be analyzed belonging to the building.

[0037] The image similarity threshold is obtained from the local database. If the image similarity of a certain cable of a distribution box to be analyzed in the building is less than the image similarity threshold, the distribution box to be analyzed is regarded as a cable damaged distribution box. Otherwise, the distribution box to be analyzed is regarded as a line aging distribution box, thereby screening the cable damaged distribution boxes and line aging distribution boxes belonging to the building.

[0038] In a specific embodiment, the image similarity of each cable of each distribution box to be analyzed belonging to a building is obtained by the following specific method: the existing image comparison technology is mature, and the image similarity of each cable of each distribution box to be analyzed belonging to a building can be obtained by the existing image comparison technology.

[0039] Step 1 of the present invention is to conduct safety analysis on the distribution boxes of a building, by first detecting whether there are any grounding problems in the distribution boxes of the building, and if there are no grounding problems, to determine whether there are any output voltage problems in the distribution boxes of the building, and if there are output voltage problems, to dispatch an intelligent robot to detect the distribution boxes with output voltage problems, and to intelligently determine the cause of the output voltage problem, thereby reducing the number of detections by the intelligent robot and ensuring that problems in the distribution boxes of the building can be detected, thereby improving the safety of electricity use in the distribution boxes.

[0040] Step 2. Building electrical shaft safety analysis: Use intelligent robots to obtain the overall internal image, humidity value, temperature value, surface image of each cable, and dust concentration value of each dust monitoring point of the electrical shafts on each floor of the building, and analyze the abnormal floors and abnormal conditions of each electrical shaft in the building.

[0041] In a specific embodiment, the internal overall image, humidity value, temperature value, surface image of each cable, and dust concentration value of each dust monitoring point of the power well on each floor of the building are obtained by a specific method: the internal overall image of the power well on each floor of the building and the surface image of each cable are obtained by a high-definition camera carried by an intelligent robot, the humidity value and temperature value of the power well on each floor of the building are obtained by a temperature sensor and a humidity sensor installed in the power well, and the dust concentration value of the power well on each floor of the building is obtained by a dust concentration sensor installed at each dust monitoring point in the power well.

[0042] It should be noted that abnormal conditions on the floors include: accumulation of debris, damaged cables, and excessive dust concentration.

[0043] In a specific embodiment of the present invention, the abnormal floors and abnormal states of each electrical shaft room belonging to a building are analyzed by a specific analysis method: image recognition is performed based on the overall internal image of the electrical shaft room on each floor belonging to the building, and each stored item is obtained in the overall internal image of the electrical shaft room on each floor belonging to the building.

[0044] The permitted storage items in the electrical shaft room of each floor of the building are obtained from the local database. If a storage item in the overall internal image of the electrical shaft room of a certain floor of the building is inconsistent with all the permitted storage items, the accumulation of debris is regarded as an abnormal state of the floor, and the floor is regarded as an abnormal floor in the electrical shaft room.

[0045] Based on the surface images of the cables between the electrical shafts on each floor of the building and the method of screening the damaged distribution boxes of the cables in the building, the floors with damaged cables in the electrical shafts of the building are screened in the same way, and the floors with damaged cables in the electrical shafts of the building are regarded as abnormal floors between the electrical shafts, and the cable damage is regarded as its abnormal state.

[0046] Analyze the dust hazard coefficient between the electrical shafts on each floor of the building, and obtain the dust hazard coefficient threshold from the local database. If the dust hazard coefficient between the electrical shafts on a floor of the building is greater than the dust hazard coefficient threshold, the excessively high dust concentration will be regarded as an abnormal state of the floor, and the floor will be regarded as an abnormal floor between the electrical shafts.

[0047] In summary, the abnormal floors and their abnormal conditions between the electrical wells of each building are summarized.

[0048] In a specific embodiment of the present invention, the dust hazard coefficient of the electrical wells on each floor of the building is analyzed, and the specific analysis method is: obtaining the space volume value of the electrical wells on each floor of the building, the allowable dust concentration value of the electrical wells in each humidity value interval, each temperature value interval and each space volume value interval from the local database, and mapping the allowable dust concentration value of the electrical wells on each floor of the building according to the humidity value and temperature value of the electrical wells on each floor of the building. , where r represents the number of each floor, , s is a positive integer greater than 2.

[0049] According to the dust concentration values ​​of each dust monitoring point in the electrical wells on each floor of the building , where t represents the number of each dust monitoring point, , w is a positive integer greater than 2, and the dust hazard coefficient between the electrical wells on each floor of the building is analyzed , where e is represented by a natural constant.

[0050] Step 2 of the present invention is to analyze the safety of the building's electrical wells. By monitoring the electrical wells on each floor of the building, the abnormal floors and their abnormal states in the electrical wells of the building can be analyzed. The problems in the electrical wells on each floor of the building can be monitored in a timely manner, and the problems in the electrical wells can be divided into detailed categories, thereby ensuring the safety of electricity use in the electrical wells of the building.

[0051] Step 3. Safety monitoring of electricity use in buildings and residences: Use drones to obtain images of the building's exterior walls along a preset inspection route to determine whether there are problems with private wiring. If so, screen the problematic residences belonging to the building.

[0052] In a specific embodiment, the method for acquiring the exterior wall image of the building is as follows: acquiring the exterior wall image of the building by a high-definition camera carried by a drone.

[0053] In a specific embodiment of the present invention, the specific screening method for screening the problem houses belonging to a building is: screening the houses to be analyzed belonging to the building based on the exterior wall image of the building.

[0054] By using image extraction technology, images of various electric wires are extracted from the exterior wall images of various houses to be analyzed belonging to the building, thereby obtaining various electric wires of various houses to be analyzed belonging to the building.

[0055] The drone is controlled to monitor items along the extension direction of each wire of each house to be analyzed in the building, until the connected items of each wire of each house to be analyzed in the extension direction are obtained.

[0056] The allowed connection items of external wires are obtained from the local database, and the connection items of each wire in the extension direction of each house to be analyzed belonging to the building are compared with the allowed connection items of external wires. If the connection items of a wire in the extension direction of a house to be analyzed belonging to the building are inconsistent with the allowed connection items of external wires, the house to be analyzed is regarded as a problem house, thereby screening the problem houses belonging to the building.

[0057] In a specific embodiment, the specific method of extracting each wire image from the exterior wall image of the housing to be analyzed belonging to the building is: using existing image extraction technology, each wire image can be extracted from the exterior wall image of each housing to be analyzed belonging to the building.

[0058] It should be noted that the extension direction is: the direction in which each wire of each house to be analyzed in the building is away from the corresponding house to be analyzed.

[0059] In a specific embodiment of the present invention, the specific screening method for screening the houses to be analyzed belonging to the building is: based on the exterior wall image of the building, using image recognition technology to determine whether there are electric wire segments in the exterior wall image of the building; if there are electric wire segments in the exterior wall image of the building, then obtaining the electric wire segments belonging to the building from the exterior wall image of the building, extracting the houses connected to the starting points of the electric wire segments belonging to the building, and using them as the houses to be analyzed, thereby screening the houses to be analyzed belonging to the building.

[0060] In a specific embodiment, the method for determining whether there are electric wire segments in the image of the exterior wall of a building is as follows: the existing electric wire image recognition technology is relatively mature, and based on the image of the exterior wall of the building, it is possible to determine whether there are electric wire segments in the image of the exterior wall of the building through the existing electric wire image recognition technology.

[0061] Step 3 of the present invention monitors the safety of electricity use in buildings. By intelligently monitoring whether there are problems of privately pulled wires, the occurrence rate of property personnel having difficulty in timely and accurately discovering the problem of privately pulled wires from the exterior walls when inspecting from outside the building due to limited vision and other reasons can be reduced, thereby reducing the incidence rate of fire in buildings.

[0062] Step 4. Building electricity safety maintenance: Send each abnormal grounding distribution box, damaged cable distribution box, aging line distribution box and problematic housing belonging to the building to the property manager, generate solutions for abnormal floors in each power well of the building based on the abnormal status, and send them to the property manager.

[0063] In a specific embodiment, the solution for generating abnormal floors of each electrical well room belonging to a building based on abnormal conditions is as follows: if the abnormal condition of an abnormal floor of an electrical well room belonging to a building is accumulation of debris, a cleaning staff is dispatched to clean the electrical well room belonging to the building.

[0064] If the abnormal status of an abnormal floor in a certain electrical well room of a building is cable damage, each repair time period will be visualized to the property manager, who will select the repair time period and notify each user of the building of the repair time period via mobile phone text messages. During the repair time period, cable repair staff will be dispatched to repair the cables in the electrical well room on the abnormal floor of the electrical well room.

[0065] If the abnormal condition of an abnormal floor in a power well room of a building is that the dust concentration is too high, an intelligent robot will be dispatched with a humidifier to humidify the power well room of the building.
