If the environmental assessment index ypg of a public area within the set time interval is greater than the preset reference threshold index, the public area with an index greater than the reference threshold index is marked as an abnormal public area;

[0029] Turn on the air purification equipment in the abnormal public area, and immediately analyze the environmental assessment index ypg of the abnormal public area within the next set time interval; if the comparison result is still greater than the preset reference threshold index, extract the maintenance assessment duration of the air purification equipment in the abnormal public area and the maintenance time point of the most recent maintenance, calculate the time difference between the maintenance time point of the most recent maintenance of the air purification equipment and the current time point, and thus obtain the maintenance interval duration of the air purification equipment; if the maintenance assessment duration of the air purification equipment in the abnormal public area is greater than the maintenance interval duration, take the abnormal public area as the starting point, screen the maintenance personnel who are closest to the starting point, and send the location of the abnormal public area to the nearest maintenance personnel; otherwise, send the location of the abnormal public area to the property management personnel.

The data pairs of the air purification equipment are input into the corresponding data pair matching library to obtain the corresponding data pair matching range. Each group of data pair matching ranges is set to correspond to a reference maintenance interval, and the reference maintenance interval obtained by matching is used as the maintenance evaluation duration of the air purification equipment.

[0033] As a preferred implementation of the present invention, the residential energy consumption index yt obtained by analysis is received and the corresponding steps are performed, specifically:

[0035] The building numbers corresponding to the numerical points above the reference line are counted as the buildings with higher electricity consumption, and the building numbers corresponding to the remaining numerical points are counted as the buildings with lower electricity consumption;

[0036] The building energy consumption index yt of the residential buildings, the buildings with higher electricity consumption, the buildings with lower electricity consumption and the constructed plane rectangular coordinate system are filled into the pre-constructed report template. After filling, it serves as the residential electricity consumption report for the set time window before the current time point.

If the power consumption of a device in the public area in the set time window before the current time point is greater than the set reference power consumption, the device with a power consumption greater than the set reference power consumption is marked as an evaluation device; analyze the hidden danger assessment index puy of the evaluation device, sort the hidden danger assessment index puy of each group of evaluation equipment from large to small, and use it as the equipment inspection sequence after sorting;

[0040] The power consumption, hidden danger assessment index puy and equipment inspection sequence of each device in the public area are filled into the pre-built report template. After filling, it serves as the power consumption report of the public area equipment in the set time window before the current time point.

[0041] As a preferred embodiment of the present invention, the hidden danger assessment index puy of the assessment equipment is obtained, and the specific steps are as follows:

[0042] Obtain the historical failure times of the evaluation equipment from the maintenance records of the evaluation equipment, recorded as pk2; calculate the maintenance interval of the evaluation equipment, recorded as pk3; according to the formula The power consumption pk1, historical failure number pk2 and maintenance interval pk3 of the evaluation equipment are weightedly calculated to obtain the hidden danger assessment index puy of the evaluation equipment; wherein ph1, ph2 and ph3 represent the reference power consumption, reference failure number and maintenance assessment time respectively; b1, b2 and b3 are the influencing weight factors of power consumption pk1, historical failure number pk2 and maintenance interval pk3 respectively.

[0043] Compared with the prior art, the present invention has the following beneficial effects:

[0044] The present invention analyzes the environmental impact parameters of each public area to obtain an environmental assessment index by presetting an environmental assessment time interval, and converts the environmental conditions into an intuitive numerical index, which is convenient for property personnel to quickly judge the quality of regional environment. At the same time, by setting a reference threshold index, abnormal public areas can be quickly screened out, realizing the visualization and precision of environmental management, so that the property has a basis for environmental management decisions. Once an abnormal public area is found, the air purification equipment is immediately started, and the effect is continuously monitored and evaluated. If the purification measures are not effective, the status of the air purification equipment is further analyzed, and maintenance personnel are accurately dispatched or the property management personnel are notified, forming a closed-loop management mechanism of active response, continuous monitoring and optimization and adjustment, which effectively ensures the continuous good quality of the public area environment.

[0045] The present invention calculates the building energy consumption index and constructs a residential electricity consumption report, counts the buildings with higher and lower electricity consumption, and displays the overall energy consumption distribution of the community and the energy consumption of each building in the form of intuitive charts and data, so that the property can quickly grasp the energy consumption situation of the community, providing a strong decision-making basis for formulating targeted energy-saving measures, and also facilitates the owners to understand their own electricity consumption level and promote energy-saving awareness.

[0046] The present invention calculates the power consumption ratio by comparing the current power consumption with the historical data, constructs a plane rectangular coordinate system to analyze energy consumption anomalies, and deeply mines the information behind the energy consumption data, thus providing more accurate data support for energy-saving management;

[0047] The present invention constructs a power consumption report for equipment in public areas, calculates a hidden danger assessment index by analyzing the power consumption of equipment, the number of historical failures, and the length of maintenance intervals, sorts the hidden dangers of the equipment to form an inspection sequence, and gives priority to equipment with high hidden dangers. This helps to promptly discover and solve problems before equipment failures occur, reduces the impact of sudden equipment failures on the normal operation of the community, improves the initiative and preventive nature of property management, and ensures the convenience of residents' lives. BRIEF DESCRIPTION OF THE DRAWINGS

[0048] In order to facilitate understanding by those skilled in the art, the present invention is further described below with reference to the accompanying drawings.

[0049] Figure 1 It is a principle block diagram of the present invention;

[0050] Figure 2 It is a schematic diagram of constructing a plane rectangular coordinate system in the present invention. DETAILED DESCRIPTION

[0051] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only 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 ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0052] See also Figure 1-2 As shown, the smart property management system based on the Internet of Things platform includes an Internet of Things module;

[0053] The IoT module includes a sensing unit, a network unit, a processing unit, and a management unit;

[0054] The sensing unit is used to collect environmental impact parameters, energy consumption performance parameters and equipment maintenance parameters in the residential area; the environmental impact parameters include the concentration of fine particles, formaldehyde content and carbon dioxide concentration in the air of the residential public area; the energy consumption performance parameters include the electricity consumption data of different buildings and public areas in the residence; the equipment maintenance parameters include the equipment type and maintenance records of various equipment in the residential public area;

[0055] It should be noted that the environmental impact parameters are collected through fine particle sensors, formaldehyde sensors and carbon dioxide sensors pre-installed in the public areas of the residential area; the public areas of the residential area include but are not limited to the entrance hall of each building in the community, the community meeting room and the underground parking lot;

[0056] Energy consumption performance parameters are measured by installing smart meters at the main distribution box of each residential building and independent smart meters in public areas. The data collection frequency of smart meters in public areas is consistent with that of building meters.

[0057] Equipment maintenance parameters are stored in a pre-built maintenance database. Every time maintenance is performed on various types of equipment in public areas, maintenance personnel need to record and upload them to the pre-built maintenance database; various types of equipment in public areas such as elevators, corridor lighting, and pump rooms;

[0058] The network unit is used to transmit the environmental impact parameters, energy consumption performance parameters and equipment maintenance parameters collected by the sensing unit to the processing unit using the pre-built IoT communication network; the IoT communication network is established in a manner that uses a wired network (Ethernet) as the backbone and a wireless network (wifi) as a supplement to ensure the timeliness and accuracy of data transmission;

[0059] It should be noted that the network uses encrypted transmission to prevent data from being stolen or tampered with during transmission.

[0060] The processing unit is used to establish a data storage library, classify and store the environmental impact parameters, energy consumption performance parameters and equipment maintenance parameters transmitted from the sensing unit, and analyze the stored environmental impact parameters and energy consumption performance parameters respectively, so as to obtain the environmental assessment index ypg and the residential energy consumption index yt; wherein g represents the number of the public area;

[0061] It should be noted that g = 1, 2, ..., k, where k is the total number of public areas.

[0062] The environmental impact parameters stored are analyzed to obtain the environmental assessment index ypg, which is:

[0063] Preset the environmental assessment time interval for each public area. After reaching the environmental assessment time interval of a certain public area, extract the concentration of fine particulate matter, formaldehyde content and carbon dioxide concentration of each preset collection point in the corresponding public area within the set time interval; each preset collection point arranges the number of sensors according to the area of ​​the corresponding public area;

[0064] Identify the highest fine particle concentration, the highest formaldehyde content and the highest carbon dioxide concentration at each preset collection point in the corresponding public area within the set time interval; and calculate the average of the highest fine particle concentration, the highest formaldehyde content and the highest carbon dioxide concentration corresponding to each preset collection point in the corresponding public area, so as to obtain the fine particle assessment value, the formaldehyde content assessment value and the carbon dioxide concentration assessment value of the corresponding public area within the set time interval;

[0065] Preset the standard reference values ​​of fine particle concentration, formaldehyde content and carbon dioxide concentration corresponding to each public area; the technical staff shall set them according to the air quality standards and the area and location of the public area;

[0066] Extract the standard reference values ​​of fine particle concentration, formaldehyde content and carbon dioxide concentration in the corresponding public areas and mark them as mag 标准 、mtg 标准 and mcg 标准 , and mark the fine particle assessment value, formaldehyde content assessment value and carbon dioxide concentration assessment value of the corresponding public area within the set time interval as mag, mtg and mcg respectively;

[0067] Substitute the fine particle assessment value mag, formaldehyde content assessment value mtg, and carbon dioxide concentration assessment value mcg of the corresponding public area within the set time interval into the formula A weighted calculation is performed to obtain the environmental assessment index ypg of the corresponding public area within the set time interval; wherein a1, a2 and a3 are the impact weight factors corresponding to the fine particle assessment value mag, the formaldehyde content assessment value mtg and the carbon dioxide concentration assessment value mcg respectively;

[0068] It should be noted that by presetting the environmental assessment time interval, environmental assessments can be conducted on public areas regularly; this ensures the timeliness of environmental monitoring. For example, for densely populated public areas in the community, such as community meeting rooms and underground parking lots, assessments can be conducted at appropriate time intervals (such as every hour or every day). This can promptly detect deterioration in air quality and provide residents with a healthier activity environment.

[0069] The stored energy consumption performance parameters are analyzed to obtain the residential energy consumption index yt, which is:

[0070] The energy consumption evaluation time interval of the buildings in the residence is preset. After the preset energy consumption evaluation time interval is reached, the cumulative power consumption of each building in the residence in the set time window before the current time point is extracted; the window is initially set to 1 month;

[0071] At the same time, extract the historical X groups of cumulative power consumption of each building in the residence and calculate the average respectively, and use the calculated average of each group as the reference power consumption of each building in the residence; X>5, the specific value is set by the technical staff;

[0072] The power consumption ratio of each building in the residence is obtained by calculating the ratio between the cumulative power consumption of each building in the set time window before the current time point and the corresponding reference power consumption, that is, the cumulative power consumption / corresponding reference power consumption;

[0073] Construct a plane rectangular coordinate system, where the horizontal axis represents the number of each building in the residence, and the vertical axis represents the size of the electricity consumption ratio. Based on the number of each building in the residence, draw the numerical points corresponding to the electricity consumption ratio of each building in the plane rectangular coordinate system, preset the reference electricity consumption ratio corresponding to the electricity consumption ratio, draw the reference line corresponding to the reference electricity consumption ratio in the plane rectangular coordinate system, count the number of numerical points above the reference line and record it as the number of abnormal energy consumption, calculate the proportion of the number of abnormal energy consumption in the total number of stairs, and record it as the energy consumption proportion;

[0074] Calculate the average of each group of numerical points above the reference line, and subtract the preset reference power consumption ratio from the calculated average to obtain the excess energy consumption;

[0075] Preset the weight coefficients corresponding to the energy consumption ratio and the energy consumption excess value, multiply the energy consumption ratio and the energy consumption excess value by the corresponding preset weight coefficients, and then sum them up to obtain the building energy consumption index yt;

[0076] It should be noted that by analyzing the building energy consumption index yt, the energy consumption status of the building can be reflected more scientifically; this index can be used as a unified indicator to provide strong support for property management to formulate energy-saving measures, investigate the causes of abnormal energy consumption, and make energy management decisions.

[0077] The management unit is used to receive the environmental assessment index ypg and the residential energy consumption index yt obtained through analysis, and execute corresponding steps;

[0078] Specifically:

[0079] Environmental assessment index ypg: preset reference threshold index of environmental assessment index ypg corresponding to each public area, receive environmental assessment index ypg of each public area within a set time interval, and compare it with the preset reference threshold index. If the environmental assessment index ypg of a public area within the set time interval is greater than the preset reference threshold index, the public area with an index greater than the reference threshold index will be marked as an abnormal public area;

[0080] Turn on the air purification equipment in the abnormal public area, and immediately analyze the environmental assessment index ypg of the abnormal public area within the next set time interval. If the comparison result is still greater than the preset reference threshold index, extract the maintenance assessment duration of the air purification equipment in the abnormal public area and the maintenance time point of the most recent maintenance, calculate the time difference between the maintenance time point of the most recent maintenance of the air purification equipment and the current time point, and thus obtain the maintenance interval duration of the air purification equipment. If the maintenance assessment duration of the air purification equipment in the abnormal public area is greater than the maintenance interval duration, take the abnormal public area as the starting point, screen the maintenance personnel who are closest to the starting point, and send the location of the abnormal public area to the nearest maintenance personnel, otherwise send the location of the abnormal public area to the property management personnel;

[0081] It should be noted that by presetting the reference threshold index and comparing the environmental assessment index ypg of each public area with it, public areas with abnormal environmental quality can be quickly screened out; once an abnormal public area is found, the air purification equipment is immediately turned on to improve the air quality at the first time, timely reduce the concentration of pollutants in the air, and reduce the impact on residents' health and living comfort. For example, in the underground parking lot of the community, if the carbon dioxide concentration is too high and the environmental assessment index ypg exceeds the reference threshold, timely turning on the air purification equipment can speed up air circulation and purification, so that the air quality can return to normal as soon as possible; after taking the measure of turning on the air purification equipment, the environmental assessment index ypg within the next set time interval is analyzed and compared again, forming a closed-loop monitoring and feedback mechanism. In this way, the effect of the measures taken can be intuitively understood. If the index is still greater than the preset threshold, it means that the current purification measures may not meet expectations and further investigation of the cause is needed, which will help to continuously ensure that the air quality of public areas is in good condition and avoid environmental problems from existing for a long time without being noticed.

[0082] The specific steps to obtain the maintenance assessment time are:

[0083] Extract the service life and failure times of the equipment from the maintenance records of the air purification equipment in the abnormal public area, and combine them into a data pair of the air purification equipment, i.e. (service life, failure times);

[0084] Set up a data pair matching library corresponding to different equipment types, extract the data pair matching library corresponding to the air purification equipment, and set each group of data pair matching ranges in the data pair matching library, i.e. (service life range, fault number range). Input the data pairs of the air purification equipment into the corresponding data pair matching library to obtain the corresponding data pair matching range. Set each group of data pair matching range to correspond to a reference maintenance interval, and use the reference maintenance interval obtained by matching as the maintenance evaluation duration of the air purification equipment.

[0085] It should be noted that the longer the service life and the more failure times occur, the shorter the corresponding reference maintenance interval will be.

[0086] Residential energy consumption index yt: Based on the building energy consumption index yt of the residential building, a residential electricity consumption report for the set time window before the current time point is constructed, and the residential electricity consumption report is sent to the property management personnel;

[0087] Construct a report on residential electricity usage for a set time window before the current time:

[0088] The building numbers corresponding to the numerical points above the reference line are counted as the buildings with higher electricity consumption, and the building numbers corresponding to the remaining numerical points are counted as the buildings with lower electricity consumption;

[0089] The building energy consumption index yt of the buildings in the residence, the buildings with higher electricity consumption, the buildings with lower electricity consumption, and the constructed plane rectangular coordinate system are filled into the pre-constructed report template, and after filling, it is used as the residential electricity consumption report of the set time window before the current time point;

[0090] It is also possible to construct a report on the power consumption of public area equipment within a set time window before the current time point, specifically:

[0091] Extract the power consumption of each device in the public area in the set time window before the current time point, recorded as pk1; the window is initially set to 1 month;

[0092] Extract the historical power consumption of each device in the public area in groups F; where F>3, the specific value is set by the technical staff; calculate the average of the power consumption of each device in the public area in groups F, and obtain the reference power consumption of each device in the public area. If the power consumption of a device in the public area in the set time window before the current time point is greater than the set reference power consumption, the device with a power consumption greater than the set reference power consumption will be marked as an evaluation device;

[0093] Obtain the historical number of failures of the evaluation equipment from the maintenance record of the evaluation equipment, recorded as pk2; calculate the maintenance interval of the evaluation equipment, recorded as pk3;

[0094] According to the formula The power consumption pk1, the number of historical failures pk2 and the maintenance interval pk3 of the evaluation equipment are weighted to obtain the hidden danger assessment index puy of the evaluation equipment; wherein ph1, ph2 and ph3 represent the reference power consumption, the reference number of failures and the maintenance assessment duration respectively; the reference number of failures is updated and set in real time according to the service life of the equipment; b1, b2 and b3 are the influencing weight factors of the power consumption pk1, the number of historical failures pk2 and the maintenance interval pk3 respectively;

[0095] The hidden danger assessment index puy of each group of assessment equipment is sorted from large to small, and the sorting is completed as the equipment inspection sequence;

[0096] Fill the power consumption, hidden danger assessment index puy and equipment inspection sequence of each device in the public area into the pre-built report template, and after filling, it will serve as the power consumption report of the public area equipment in the set time window before the current time point;

[0097] It should be noted that by extracting the power consumption pk1 of each device in the public area within a specific time window (initial setting is 1 month), and combining the power consumption of the historical F group (F>3) to calculate the reference power consumption, a long-term and short-term comprehensive consideration of the energy consumption of the equipment is formed. This makes it possible to accurately grasp the energy consumption level of each device at different stages, and timely discover whether the current energy consumption of the device deviates from the normal range. For example, it can quickly identify that the power consumption of the lighting equipment in a certain public area this month has increased significantly compared with the average power consumption in the past few months, which helps to accurately locate the individual equipment with abnormal energy consumption and provide a reliable data basis for further analysis and resolution of energy consumption problems; based on the comparison of the current power consumption of the equipment with the reference power consumption, the equipment with a power consumption greater than the reference power consumption is marked as an evaluation equipment, realizing the active screening of equipment with possible abnormal energy consumption; this active early warning mechanism can detect the energy consumption problem of the equipment in the early stage of its emergence, avoiding energy waste caused by long-term high energy consumption without being discovered, and helping property management personnel to intervene in advance and take corresponding measures such as checking the operating status of the equipment and checking whether there are hidden faults, so as to effectively control the overall energy consumption cost of the public area.

Obviously, many modifications and changes can be made according to the content of this specification.
