Description

Technical Field

[0001] The present invention relates to the field of urban management, and in particular to a method, system and storage medium for monitoring urban sanitation buildings based on big data technology. Background Art

[0002] With the continuous development of social economy, the incremental construction of public facilities in cities has gradually entered the stage of quality improvement and transformation from stock construction. The traditional construction that focuses on single-function infrastructure lacks aesthetics and publicity. Although it has the basic functions of public facilities, it is easy to produce NIMBY effect due to the environmental pollution risks caused by public facilities and the impact on the physical and mental health of surrounding residents.

[0003] Based on the functionality and necessity of public facilities in urban construction or urban management, and faced with the possible impact of public facilities on the surrounding environment or the physical and mental health of residents, the existing public facility supervision methods are lagging behind, lack consideration of the spirit of the place, and are inconsistent with the surrounding social and spatial characteristics.

[0004] Taking sanitation buildings as an example, conventional sanitation building monitoring requires personnel to be on duty regularly, and to sort out the garbage inside the sanitation building or clean the surrounding environment based on what the personnel observe. Regular monitoring of sanitation buildings by personnel can only be based on the amount of garbage accumulated in the sanitation buildings or the pollution of the surrounding environment. However, as people's requirements for living environment increase, and considering the impact of pollutants brought by sanitation buildings with atmospheric diffusion on the physical and mental health of surrounding residents, the existing sanitation building monitoring and management methods do not meet the above-mentioned people's requirements for the cleanliness of sanitation buildings and pollutant emissions, and are prone to produce NIMBY effects, resulting in the monitoring and management of sanitation buildings failing to keep up with the development of social needs. In addition, the monitoring and maintenance efficiency of existing sanitation buildings is low, which is not conducive to the development of urban management or urban planning. Summary of the invention

[0069] The sources of garbage in cities are widely distributed. If garbage is directly transported from various sources to the final treatment site, it will cause confusion in transportation routes, increase transportation time and costs. Various types of sanitation buildings set up in cities can serve as intermediate nodes to centrally collect and preliminarily treat garbage, and then transport it to the final treatment site, thereby improving the efficiency of urban garbage treatment in urban management.

[0070] However, existing urban sanitation buildings focus on a single function. For example, they only pay attention to the efficiency of garbage disposal in sanitation buildings, lack consideration of the relationship between sanitation buildings and urban form or building quality, and also lack consideration of the correlation between the particularity of sanitation buildings and the development of the surrounding environment. As a result, existing sanitation buildings only focus on engineering and functionality, lack the spirit of place, cannot complement the urban environment, and are easily disconnected from the surrounding environment, forming an isolated barrier. If the isolation of sanitation buildings from the surrounding environment gradually increases, combined with their special functions, it is easy to cause certain NIMBY problems.

[0071] The present invention provides a method for monitoring urban sanitation buildings based on big data technology. Based on the environmental monitoring data collection of sanitation buildings by the urban sanitation building monitoring system and the real-time feedback information from the maintenance terminal, the sanitation buildings are monitored and maintained. This method is applied to a terminal device as an example for explanation. Figure 1 A schematic diagram of a method for monitoring urban sanitation buildings based on big data technology is shown.

The sanitation building control center is provided with a terminal device, which includes but is not limited to a smart phone and a computer device, wherein the computer device can be at least one of a desktop computer, a portable computer, a laptop computer, a mainframe computer, a tablet computer and the like. When the terminal device receives the environmental monitoring information fed back by the environmental detector on the sanitation building, it obtains the area information and population density information around the sanitation building in combination with the GIS map stored on the terminal device or the externally connected GIS map device, determines the specific weights of various pollutants and obtains the average impact of various pollutants on the population in the area; and combines the maintenance urgency determined by the operating status information of the equipment in the sanitation building fed back by the operating detector, the transferable information fed back by the garbage transfer equipment and the complaint information fed back by the public opinion platform, generates the optimal maintenance work order for the sanitation building, and sends it to the equipment in the sanitation building or the garbage transfer equipment.

[0073] First, combine the attached Figure 2 The schematic diagram of the urban sanitation building monitoring system based on big data technology is shown, and the specific structure of the urban sanitation building monitoring system based on big data technology is explained. The urban sanitation building monitoring system based on big data technology includes at least one sanitation building, an environmental detector installed on the sanitation building, an operation detector installed on the sanitation building, a sanitation building control center, a public opinion platform and garbage transfer equipment. The environmental detector, operation detector, garbage transfer equipment, public opinion platform and sanitation building control center are communicatively connected.

[0074] The environmental detector installed on the sanitation building includes at least one of an odor sensor, a temperature sensor, a humidity sensor, and a harmful gas sensor, which is used to monitor the odor concentration emitted by the sanitation building, the temperature inside the sanitation building, the humidity inside the sanitation building, and the concentration of harmful gases emitted by the sanitation building. Furthermore, in the environmental detector of this embodiment, at least one odor sensor and harmful gas sensor can be set in four directions outside the sanitation building respectively, to monitor the corrupt odor and harmful gases emitted by the sanitation building. The temperature sensor and humidity sensor of this embodiment can be set at the top or middle of the inner side of the sanitation building to monitor the temperature and humidity inside the sanitation building.

[0075] Furthermore, the environmental detectors installed on the sanitation building may also include image detectors or weight detectors for monitoring the volume or weight of garbage accumulated in the sanitation building; wherein, the image detector can be set at the top or middle of the inner side of the sanitation building to collect image information of garbage accumulated in the sanitation building; the weight detector can be set at the bottom of the inner side of the sanitation building to collect weight information of garbage accumulated in the sanitation building.

[0076] The operation detectors installed on the sanitation buildings are used to monitor the real-time and historical operating status of the garbage disposal equipment inside the sanitation buildings, where the garbage disposal equipment inside the sanitation buildings includes but is not limited to garbage compressors, garbage ventilation systems, garbage odor purification systems and harmful gas adsorption systems; the garbage compressors can compress the accumulated garbage inside the sanitation buildings to increase the garbage holding capacity of the sanitation buildings; the garbage ventilation systems are used to ventilate the interior of the sanitation buildings, reduce the temperature rise or humidity accumulation in the sanitation buildings, and reduce the rate of garbage decay; the garbage odor purification system is used to purify the corrupt odors emitted by the sanitation buildings, and reduce the impact of the corrupt odors emitted by the garbage on the surrounding residents; the harmful gas adsorption system is used to adsorb harmful gases emitted by the sanitation buildings and reduce the emission of harmful gases.

[0077] The public opinion platform can be the public opinion platform of the unit to which the sanitation building belongs, or it can be a public opinion platform similar to the government public hotline. The public opinion platform receives various complaint information, and records and classifies it according to the complaint content and the specific sanitation building location or number it points to. It can feedback the real-time complaint information received by the specific sanitation building to the sanitation building control center, and adjust the maintenance strategy or comprehensive score of the sanitation building with reference to the real-time complaint information.

[0078] The garbage transfer equipment is specifically a garbage transfer vehicle, and at least one of an image acquisition device, an ultrasonic detection device, and a weight detection device may be provided inside the garbage transfer equipment, wherein the image acquisition device or the ultrasonic detection device is provided at the top or side of the inner side of the garbage transfer equipment compartment, and the loadable capacity of the garbage transfer equipment can be determined by collecting images of the inner side of the compartment or ultrasonic feedback signals, and the weight detection device may be provided at the bottom of the inner side of the garbage transfer equipment compartment, and the loadable capacity of the garbage transfer equipment may be determined by combining the loadable weight of the garbage transfer equipment with the loaded weight. In addition, a positioning device and a communication device are also provided inside the garbage transfer equipment, wherein the positioning device is used to obtain the real-time positioning information of the garbage transfer equipment, and the communication device is used to send the loadable capacity and real-time positioning information of the garbage transfer equipment to the sanitation building control center, so that the sanitation building control center can combine the monitoring conditions of the sanitation buildings near the garbage transfer equipment, and the loadable capacity and real-time positioning information of the garbage transfer equipment, and deploy the garbage transfer equipment with the best path to realize garbage transfer for the specific sanitation building.

[0079] Based on the above-mentioned urban sanitation building monitoring system based on big data technology, the urban sanitation building monitoring method based on big data technology of this embodiment is applied on the terminal device of the sanitation building control center, and performs the following specific steps:

[0080] Step S101, obtaining environmental monitoring information fed back by environmental detectors, and real-time wind speed and real-time wind direction in the area where the sanitation building is located, wherein the environmental detector includes an odor sensor, a humidity sensor and a harmful gas sensor, and the environmental monitoring information includes at least one pollutant emission concentration and humidity in the area where the sanitation building is located.

[0081] Specifically, the odor sensor in the environmental detector is used to obtain the concentration of the decayed odor emitted by the sanitation building, the humidity sensor is used to obtain the humidity of the area where the sanitation building is located, and the harmful gas sensor is used to obtain the concentration of the harmful gas emitted by the sanitation building. Therefore, the pollutant emission concentration in the environmental monitoring information in this embodiment at least includes the decayed odor concentration and the harmful gas concentration.

[0082] The real-time wind speed and real-time wind direction in the area where the sanitation building is located can be measured in real time by wind speed and direction sensors in the area where the sanitation building is located, or the real-time wind speed and real-time wind direction of each urban area can be directly obtained through the communication connection between the sanitation building control center and the real-time weather database.

[0083] The odor sensor is similar to the human body's olfactory mechanism and can be used to monitor the putrefactive odor emitted by garbage in sanitation buildings and obtain the putrefactive odor concentration emitted by the sanitation buildings in all directions, which is measured in ppm. To improve the reliability of the collected data, several odor concentration data of the sanitation buildings in four directions can be collected in a preset time period, and the average odor concentration or peak odor concentration in each direction in the time period can be calculated as a reference value for the odor concentration emitted by the sanitation buildings in this embodiment.

[0084] Since excessive temperature and humidity may affect the diffusion speed and diffusion range of specific pollutants in sanitation buildings, and may also accelerate the speed of garbage decay and harmful gas generation, increase the burden of sewage treatment, promote the growth of microorganisms, and affect the operating life of sanitation buildings or equipment, this embodiment is provided with at least one temperature sensor and humidity sensor at the sanitation building, and the temperature sensor and humidity sensor can be arranged together at the top or middle of the inner side of the sanitation building, or separately at the optimal environment collection point at the sanitation building, for objectively expressing the temperature and humidity of the sanitation building as a whole. It should be noted that, considering the influence of the fermentation and decay of garbage inside the sanitation building on the temperature and humidity, the temperature sensor and humidity sensor of this embodiment are not arranged at the bottom of the inner side of the sanitation building, so that the obtained temperature data and humidity data reduce the influence of the local environment. In order to improve the reliability of the collected data, a number of temperature data and humidity data fed back by the temperature sensor and humidity sensor inside the sanitation building can be collected within a preset time period, and the average temperature or peak temperature, average humidity or peak humidity within the time period are calculated as the reference value of the temperature and humidity in the sanitation building in this embodiment.

[0085] During the garbage decay process, organic components produce harmful gases under the action of microbial decomposition, such as hydrogen sulfide and ammonia; or chemical reactions involving chlorine-containing organic matter (such as plastics) in garbage or heavy metals in waste batteries produce harmful gases; the above-mentioned harmful gases will have different degrees of impact on the health of people near sanitation buildings, so harmful gas sensors can be set up in four directions of sanitation buildings to monitor the concentration of harmful gases. In order to improve the reliability of collected data, several harmful gas concentration data of sanitation buildings in four directions can be collected in a preset time period, and the average harmful gas concentration or peak harmful gas concentration in each direction in the time period can be calculated as a reference value of the concentration of harmful gases emitted by the sanitation building in this embodiment.

[0086] Step S102, inputting the pollutant emission concentration, the humidity of the area where the sanitation building is located, and the real-time wind speed and real-time wind direction in the area where the sanitation building is located into the improved Gaussian plume model to obtain the pollution degree of various pollutants to the area where the sanitation building is located.

[0087] Specifically, the R&D team fully considered the impact of humid environments (such as the Guangdong and Guangxi regions or plum rain weather) on the diffusion of pollutants and human senses. In order to more accurately determine the impact of environmental monitoring information on the actual location points, the humidity parameters were introduced according to the humid environment, and the Gaussian plume model was adjusted and improved. The pollution degree of various pollutants to the area where the sanitation building is located was calculated by combining the actual wind direction data and the improved Gaussian plume model. The specific expression is:

[0088] ,

[0089] in, For the The vertical distance of sanitation buildings , lateral distance The pollution level of the monitoring point, Indicates the downwind distance, Indicates the crosswind distance, Indicates the real-time wind speed. For the The concentration of pollutants discharged, is the humidity-related crosswind diffusion parameter, is the humidity-related vertical diffusion parameter, is the humidity of the area where the sanitation building is located. In this embodiment, the types of pollutants include corrupted gases and harmful gases. Further, it can also include fine particle pollutants in the sanitation building.

[0090] Regarding the above-mentioned improved Gaussian plume model, it should be noted that the model is trained in combination with the historical wind speed data and historical wind direction data of the area where the sanitation building is located, and a garbage station gas diffusion model is constructed based on the improved Gaussian plume model. Taking into account the inconsistent duration of weather and humidity in various regions, changes in near-ground humidity will change the structure of the atmospheric boundary layer. In a high-humidity environment, the increase in water vapor will reduce the air density, resulting in changes in the vertical welfare effect, just like changing the trend of pollutants rising or settling in a "local environment", thereby affecting diffusion. For example, when the humidity increases, a relatively stable water vapor layer may be formed near the ground. This water vapor layer will inhibit the vertical diffusion of pollutants, making it easier for pollution to accumulate near the ground; conversely, when the humidity is low, vertical diffusion may be relatively easier, and pollutants can diffuse upward faster and be diluted. Since this embodiment mainly focuses on the concentration of pollutants near the ground, take , and the sanitation building is a ground source, ,After considering the influence of humidity on the diffusion parameters, the model is improved, and humidity is introduced as an influencing factor into the calculation of the diffusion parameters and .

[0091] In addition, in this embodiment, according to the historical measurement data, the fitting coefficient of the crosswind direction is fitted by nonlinear regression analysis and other methods, and the reaction coefficient variables affected by humidity and temperature of different pollutants are further considered. The crosswind diffusion parameter expression is , , and are fitting coefficients, is the reaction coefficient of a specific pollutant; similarly, the vertical diffusion coefficient , and are fitting coefficients, The weight of humidity factor in changing the vertical diffusion coefficient.

[0092] Step S103, determining the average impact of various pollutants emitted by the sanitation building on the population in the area in which the sanitation building is located in combination with the population size and pollution level.

[0093] Specifically, determining the average impact of various pollutants on the population in the area where the sanitation building is located in combination with the population size of the area includes the following steps:

[0094] Step S201, determining the exposure amount of the population in the area where the sanitation building is located to various pollutants according to the population size of the area where the sanitation building is located and the pollution degree of various pollutants to the area where the sanitation building is located.

[0095] When evaluating sanitation buildings, the surrounding area is divided into different grids with the sanitation building as the center point, the number of people in each grid area is counted, and the population exposure calculation of each wind direction is considered. and wind speed Under the influence of , the pollutant concentration is , the pollutant exposure impact of each grid area, the specific expression is:

[0096] ,

[0097] in, For real-time wind speed and real-time wind direction angle The following sanitation buildings emit The amount of pollutants that the regional population is exposed to, is the population of the area where the sanitation building is located, For real-time wind speed and real-time wind direction angle Next The degree of contamination of the pollutants.

[0098] It should be noted that the population size of the area where the sanitation building is located can be obtained based on the permanent population size registered on the GIS map, or it can be obtained based on the real-time population size counted by the signal transceiver equipment at the location of the sanitation building.

[0099] Step S202, combining the exposure of the population in the area where the sanitation building is located to various pollutants and the frequency of occurrence of various wind speed and wind direction angle combinations, determines the average impact of various pollutants emitted by the sanitation building on the regional population.

[0100] Among them, since different wind speeds and wind directions occur at different frequencies, the combined weight of each wind speed and wind direction is further determined based on the meteorological data within a preset period. have interval, wind direction angle have intervals, the frequency of wind speed interval and wind direction interval combination is , the comprehensive average impact degree is calculated, and the specific expression is:

[0101] ,

[0102] in, Wind speed and wind direction angle The combination of sanitation buildings emits the first The amount of pollutants that the regional population is exposed to, Wind speed and wind direction angle The population of the area where the sanitation building is located under the combination of Wind speed and wind direction angle The frequency of the combination, The first The average impact of a pollutant on the regional population. The average impact of the regional population reflects the risk level of the population around the garbage station being exposed to the potential environmental impact of the garbage station (such as odor, harmful gases, etc.). The higher the index, the greater the risk. is the number of wind speed intervals, is the number of wind direction angle intervals.

[0103] Step S104, determining the environmental impact index of the sanitation building according to the real-time weights corresponding to various pollutants in the attributes of the area where the sanitation building is located and the average impact of various pollutants on the population in the area.

[0104] Specifically, considering the different attributes of the areas where sanitation buildings are located, the degree of emphasis on various pollutants in the process of calculating environmental impact indicators is different. For example, in areas with high medical attributes or sanitation attributes (the area where the sanitation building is located is a hospital, or the area where the sanitation building is located has a large area of ​​​​a hospital, or the area where the sanitation building is located is a residential area, or the area where the sanitation building is located is a combination of a hospital and a residential area), more emphasis is placed on whether the sanitation building emits harmful gases. In areas with high educational attributes or chemical research attributes (the area where the sanitation building is located is a school, or the area where the sanitation building is located is a chemical research institute), more emphasis is placed on whether the sanitation building emits corrosive gases and harmful gases. Therefore, the real-time weights corresponding to various pollutants are set according to the attributes of the area where the sanitation building is located. The real-time weight setting corresponding to various pollutants in the above-mentioned regional attributes can be obtained based on the reference data statistics of existing materials, or based on the historical data statistics of neighboring areas of the same type.

[0105] It should be noted that the regional attributes of the sanitation building include at least one attribute, including but not limited to industrial area, tourist area, residential area, commercial area, medical area, and educational area; the regional attributes can be determined according to the regional attributes marked on the GIS map, and the smaller the area where the sanitation building is located, the simpler the regional attributes. For example, the area where the sanitation building is located is only a 1-kilometer area with the sanitation building as the center point, and the regional attributes only include residential areas or commercial areas. When the area where the sanitation building is located is a 10-kilometer area with the sanitation building as the center point, the regional properties include residential areas, commercial areas and medical areas, and the proportion of the attributes of each area is determined in combination with the size of the area occupied by each area.

[0106] The specific expression of the environmental impact index of the above sanitation buildings is:

[0107] ,

[0108] in, is the environmental impact indicator of sanitation buildings. The area where the building is located The real-time weight corresponding to the pollutant The real-time weights corresponding to the pollutants are determined according to the attributes of the area where the building is located. is the number of pollutant types.

[0109] Step S105: if the environmental impact index of the sanitation building is higher than a set threshold, a maintenance work order is generated and sent to the garbage transfer equipment or the maintenance equipment in the sanitation building.

[0110] Specifically, the setting threshold of the environmental impact index can be determined based on the corresponding historical environmental impact indicators in the historical maintenance records of the sanitation building. For example, the historical temperature, historical humidity and historical environmental impact indicators in the historical maintenance records of the sanitation building are input into the trained neural network to determine the specific setting threshold for the sanitation building to be maintained under real-time temperature and humidity. The median or average of the historical environmental impact indicators in the historical maintenance records of the sanitation building can also be used as the specific setting threshold.

[0111] The urban sanitation building monitoring method based on big data technology proposed in this embodiment is equipped with multiple environmental detectors at the sanitation building to feedback the concentration of various pollutants and the humidity of the area where the sanitation building is located. Combined with the influence of humidity, real-time wind speed and wind direction in the area where the sanitation building is located, the improved Gaussian plume model is used to obtain the pollution degree of various pollutants in the area where the sanitation building is located; and under the comprehensive consideration of the real-time weights of various pollutants determined by the attributes of the area where the sanitation building is located and the number of people in the area, the specific environmental impact index of the sanitation building is obtained by combining the pollution degree of various pollutants in the area where the sanitation building is located, and the corresponding sanitation building maintenance work order is generated according to the environmental impact index. The improved Gaussian plume model is introduced to take into account the influence of environmental humidity, wind direction and wind speed on actual pollutant emissions, and further combine the number of people in the area to determine the influence of pollutant emissions. Compared with the prior art that only maintains sanitation buildings based on parameters collected by environmental detectors, the environmental factors and personnel influence factors of the area where the sanitation building is located are comprehensively considered, and the health or experience of residents is appropriately measured in the management of urban sanitation buildings, so as to improve the quality of sanitation building detection data and management.

[0112] Further, based on the above embodiment, taking into account the mobility of people in different areas of the city and the different emphasis on various pollutants under different population densities, when the real-time weights of various pollutants are determined according to regional attributes, the real-time weights of various pollutants are corrected in combination with the change rate of the number of people in the region, specifically:

[0113] Step S301, obtaining the real-time weights corresponding to various pollutants in the attributes of the area where the sanitation building is located, the historical population number and the real-time population number of the area where the building is located.

[0114] Step S302, according to the ratio of the historical population to the real-time population of the area where the sanitation building is located, correct the real-time weights corresponding to various pollutants in the attributes of the area where the sanitation building is located, and obtain the first correction weights corresponding to various pollutants in the attributes of the area where the sanitation building is located.

[0115] Among them, the expression of the first correction weight corresponding to various pollutants is:

[0116] ,

[0117] in, For the The first correction weight of the pollutant, For the The real-time weight of pollutants, The area where the sanitation building is located The upper limit of environmental parameters of pollutants It is the ratio of the population at the location of the sanitation building in the previous time period and the current time period.

[0118] Step S303, determining the environmental impact index of the sanitation building according to the first correction weights corresponding to various pollutants in the attributes of the area where the sanitation building is located and the average impact of various pollutants on the population of the area.

[0119] Specifically, under the adjustment of the first correction weight, the specific expression of the environmental impact index is:

[0120] .

[0121] Furthermore, based on the above embodiment, considering that the attributes of various areas in the city are not static, after the regional attributes change, the emphasis on various pollutants in the area will also change accordingly. In this regard, the real-time weights of various pollutants are corrected in combination with the change rate of the number of people in the area and the change of regional attributes, specifically:

[0122] Step S401, obtaining the real-time weights corresponding to various pollutants in the attributes of the area where the sanitation building is located, the historical attribute values ​​and real-time attribute values ​​of the area where the sanitation building is located, and the historical population and real-time population of the area where the sanitation building is located.

[0123] Among them, various regional attributes are assigned values ​​according to the requirements of various regional attributes for the cleanliness of the atmospheric environment in urban management. The higher the requirements of the regional attributes for the cleanliness of the atmospheric environment, the higher the regional attribute value, and the lower the regional attribute requirements for the cleanliness of the atmospheric environment, the lower the regional attribute value. For example, among common regional attributes, the attribute value of the medical area is higher than that of the educational area, and the attribute value of the residential area is higher than that of the commercial area.

[0124] Step S402, according to the ratio of the historical attribute value to the real-time attribute value of the area where the sanitation building is located, and the ratio of the historical population to the real-time population, correct the real-time weights corresponding to various pollutants to obtain the second corrected weights corresponding to various pollutants in the attributes of the area where the sanitation building is located.

[0125] Among them, the expression of the second correction weight corresponding to various pollutants is:

[0126] ,

[0127] in, For the The second correction weight of the pollutant, For the The real-time weight of pollutants, The area where the sanitation building is located The upper limit of environmental parameters of pollutants is the ratio of the population at the location of the sanitation building in the previous time period to the current time period, It is the ratio of the historical attribute value to the real-time attribute value of the area where the sanitation building is located.

[0128] Step S403, determining the environmental impact index of the sanitation building according to the second correction weights corresponding to various pollutants in the attributes of the area where the sanitation building is located and the average impact of various pollutants on the population of the area.

[0129] Specifically, under the adjustment of the second correction weight, the specific expression of the environmental impact index is:

[0130] .

[0131] Furthermore, based on the above embodiment, considering that the real-time feedback from residents around the sanitation building can also be used as one of the monitoring data for whether the sanitation building needs maintenance, the sanitation building monitoring method based on big data in this embodiment also includes:

[0132] Step S501, receiving real-time complaint information fed back by the public opinion platform within a set time period.

[0133] Specifically, the public opinion platform (such as the 12345 hotline or the 12369 hotline) is connected to the sanitation building control center. The public opinion platform collects residents' real-time complaints and sends them to the sanitation building control center at a set time period (such as 3 hours, 6 hours). Each real-time complaint information includes the user's location, complaint time and complaint content.

[0134] Step S502: Filter the complaint information set corresponding to the sanitation building according to the user location of the real-time complaint information or the sanitation building number information included in the complaint content.

[0135] Specifically, the implementation complaint information is summarized into the complaint information set of the nearest sanitation building according to the user's location, or the specific sanitation building is determined according to the sanitation building number information in the complaint content and summarized into the complaint information set of the sanitation building. The number information of the sanitation building includes the specific number or the name of the street where the sanitation building is located. For example, each sanitation building in the city is set with a specific number, or each sanitation building is numbered according to the name of the street where it is located.

[0136] Step S503: input the complaint information set into the trained text recognition model to obtain the types of pollutants complained about and the urgency of maintenance included in the complaint content.

[0137] Specifically, each complaint information is recorded in the format of "opinion time + user location + message content", such as complaint information 1 of No. 010 sanitation building is specifically "A time + user location B (50 meters away from No. 010 sanitation building) + the area around No. 010 sanitation building is very smelly", complaint information 2 is specifically "C time + user location D (located in the northeast direction of No. 010 sanitation building, 100 meters away) + the nearby garbage station has a strong smell of decay", and complaint information 3 is specifically "E time + user location F (in the community next to No. 010 sanitation building) + the smell from the garbage station is very pungent, deal with it quickly"; the above complaint information is combined with the trained text recognition model (such as BERT model or LSTM model) to extract the pollution in the complaint information The types of pollutants and the maintenance urgency, among which the types of pollutants are determined according to specific trigger words (such as "very smelly", "dead rat smell", etc., which refer to corrupt gases, and "rotten egg smell", "pungent", etc., which refer to harmful gases); the maintenance urgency is determined according to specific emotional words (such as "faintly emitting a stench", "occasionally passing by and stinking", "very smelly", "strong corrupt smell" and "very pungent"). The maintenance urgency of sanitation buildings can be set to three levels: high, medium and low. The higher the maintenance urgency of the sanitation building, the greater the impact of the sanitation building on the surrounding residents and the more timely processing is needed. Therefore, the time limit of the high-level maintenance urgency is < the time limit of the medium-level maintenance urgency is < the time limit of the low-level maintenance urgency.

[0138] Step S504: If the types of pollutants and maintenance urgency included in the complaint content are consistent with the environmental monitoring information fed back by the environmental detector, the maintenance status information of the sanitation building is obtained and fed back to the public opinion platform for replying to the real-time complaint information.

[0139] Specifically, when the type of pollutant in the complaint points to corrosive gas and the maintenance urgency points to a high level, if the concentration of corrosive gas reported by the environmental detector at this time exceeds the standard value by more than a first ratio (such as 30% or 50%), then the content of the complaint is consistent with the environmental monitoring information reported by the environmental detector. At this time, the maintenance status information of the sanitation building is obtained, including the execution time of the maintenance work order and the maintenance measures of the maintenance work order (such as transferring garbage), and is fed back to the public opinion platform for replying to real-time complaint information.

[0140] Furthermore, in combination with the above complaints, complaints about sanitation buildings can also be fed back to the rectification or reconstruction process of sanitation buildings in urban management, specifically:

[0141] If the frequency of complaint information in the complaint information set corresponding to the sanitation building exceeds the complaint frequency threshold (for example, the frequency of complaint information is 30 times / hour, and the complaint frequency threshold is 20 times / hour), and the frequency at which the environmental impact index of the sanitation building is higher than the set threshold exceeds the maximum maintenance frequency (the frequency at which the environmental impact index is higher than the set threshold is 1 time / day, and the maximum maintenance frequency is 0.3 times / day), an alarm for rectification or reconstruction of the sanitation building is issued.

[0142] Furthermore, based on the above complaint content, the real-time weights corresponding to various pollutants can be adjusted in combination with the types of pollutants corresponding to the complaint content and the specific maintenance urgency, as follows:

[0143] Step S601, obtaining a set of historical complaint information of sanitation buildings in the previous period.

[0144] Step S602, based on the types of pollutants and maintenance urgency included in the complaint content in the historical complaint information set, correct the real-time weights corresponding to various pollutants in the attributes of the area where the sanitation building is located, and obtain the third corrected weights corresponding to various pollutants in the attributes of the area where the sanitation building is located.

[0145] The specific expression of the third correction weight is:

[0146] ,

[0147] For the The third correction weight corresponding to the pollutant, It is the first The real-time weights corresponding to the pollutants, is the number of complaints, For the Among the complaints, The maintenance urgency of the pollutant is 2 for high-level maintenance urgency, 1 for medium-level maintenance urgency, and 0 for low-level maintenance urgency.

[0148] Step S603, determining the environmental impact index of the sanitation building according to the third correction weights corresponding to various pollutants in the attributes of the area where the sanitation building is located and the average impact of various pollutants on the population of the area.

[0149] Specifically, under the adjustment of the third correction weight, the specific expression of the environmental impact index is:

[0150] .

[0151] Furthermore, for the statistics of the above complaints, the types of pollutants corresponding to the complaint information set related to sanitation buildings can be determined based on the sentiment words associated with sanitation buildings. For example, the environmental monitoring information corresponding to "very smelly" and "strong smell of decay" is the concentration of decayed gases emitted by sanitation buildings, and the environmental monitoring information corresponding to "very pungent" is the concentration of harmful gases emitted by sanitation buildings. The above correspondence can be obtained by combining the random forest decision tree trained with historical data.

[0152] The sentiment words associated with sanitation buildings in the message content of the historical complaint information set and the corresponding environmental monitoring information are input into the random forest decision tree for training until the overlap rate between the predicted environmental monitoring information of the sentiment words associated with sanitation buildings in the historical complaint information set after training and the historical environmental monitoring information reaches a preset ratio, and the trained random forest decision tree is output; and the specific sentiment words in the specific sanitation building complaint information received by the sanitation building control center can be input into the trained random forest decision tree to obtain the specific environmental monitoring information corresponding to the sentiment words.

[0153] It should be noted that if the complaint information received by the sanitation building is inconsistent with the environmental monitoring information of the sanitation building, for example, the complaint information of the sanitation building feedbacks that the sanitation building has a strong corrosive odor or pungent odor, but the odor concentration or harmful gas concentration in the environmental monitoring information of the sanitation building is within the preset acceptable range, then there may be errors in the sanitation monitoring information at this time. In order to improve the real-time monitoring efficiency of the sanitation building and the timely feedback efficiency of the complaint information of the surrounding residents, it is necessary to return to re-acquire the environmental monitoring information fed back by the environmental detector to avoid errors in the collected data. Furthermore, if the number of times the information fed back by the complaint information is inconsistent with the environmental monitoring data of the sanitation building exceeds the fault tolerance threshold, a maintenance work order is generated and sent to the maintenance end corresponding to the sanitation building to check whether the environmental detector of the sanitation building is invalid or damaged.

[0154] In addition, in a more specific implementation, based on the above-mentioned urban sanitation building monitoring method based on big data technology, the setting of specific maintenance work orders and maintenance measures includes the following two situations:

[0155] Step S701, if the environmental impact index of the sanitation building is higher than the set threshold, obtain the garbage capacity that needs to be processed in the sanitation building, the maintenance urgency of the complaint information set received by the sanitation building, and the transportability information of the garbage equipment.

[0156] Step S702: If the garbage processing capacity, maintenance urgency and transfer information in the sanitation building do not meet the first transfer condition, a first maintenance work order is generated according to the environmental monitoring information and sent to the equipment in the sanitation building.

[0157] Specifically, if the shortest path time to the sanitation building in the transferable information exceeds the time limit corresponding to the maintenance urgency, and / or the loading capacity in the transferable information does not meet the garbage processing capacity of the sanitation building, then the garbage processing capacity of the sanitation building, the maintenance urgency and the transferable information do not meet the first transfer condition.

[0158] Step S703: If the garbage capacity to be processed, the maintenance urgency and the transfer information in the sanitation building meet the first transfer condition, a second maintenance work order is generated based on the garbage capacity to be processed, the maintenance urgency and the transfer information in the sanitation building, and sent to the garbage transfer equipment.

[0159] Specifically, if the shortest path time to the sanitation building in the transferable information does not exceed the time limit corresponding to the maintenance urgency, and the loadable capacity in the transferable information meets the garbage processing capacity of the sanitation building, then the garbage processing capacity of the sanitation building, the maintenance urgency and the transferable information meet the first transfer condition.

[0160] It should be noted that the transferable information of the garbage transfer equipment includes the loadable capacity of the garbage transfer equipment and the shortest path time for the garbage transfer equipment to reach the sanitation building. The garbage transfer equipment is provided with an image sensor or a weight sensor, and the image sensor is used to collect the remaining space in the garbage transfer equipment, and calculate the loadable capacity of the garbage transfer equipment according to the remaining space; the weight sensor is used to collect the weight of the loaded garbage in the garbage transfer equipment, and calculate the loadable capacity of the garbage transfer equipment according to the weight of the loaded garbage. The shortest path time for the garbage transfer equipment to reach the sanitation building can be determined by the real-time position fed back by the garbage transfer equipment, the path planning fed back by the GIS map, the real-time congestion of each planned path, and the Dijkstra algorithm.

[0161] Furthermore, considering that the impact of sanitation buildings on surrounding residents varies, and that garbage transfer equipment may pass through multiple sanitation buildings during regular garbage transfer, on this basis, combined with the maintenance urgency determined by the complaint information fed back from the public opinion platform, the maintenance work orders are prioritized to obtain a second maintenance work order, so that the garbage transfer equipment can prioritize the maintenance of sanitation buildings that have a more serious impact on surrounding residents according to the second maintenance work order, thereby improving the social needs in the monitoring and maintenance process of sanitation buildings. For example, the regular route of the garbage transfer equipment passes through sanitation buildings #011, #010, and #012 in sequence, but during this time period, sanitation building #010 received the most complaint information and its maintenance urgency was the highest, so the garbage from sanitation building #010 is prioritized for transfer in the actual transfer route of the garbage transfer equipment.

[0162] Furthermore, this embodiment generates a maintenance work order for a sanitation building based on the environmental impact indicators of various pollutants. In order to further refine the specific execution steps of the maintenance work order, the environmental monitoring information in the sanitation building can also be refined:

[0163] Step S801, the environmental detectors installed in the sanitation building include odor sensors, temperature sensors, humidity sensors and harmful gas sensors, and the environmental monitoring information includes the concentration of corrupt gases emitted by the sanitation building, the concentration of harmful gases, and the temperature and humidity of the area where the sanitation building is located.

[0164] Step S802, determining the odor pollution index according to the concentration of corrupted gases emitted by the sanitation building, determining the harmful gas pollution index according to the concentration of harmful gases emitted by the sanitation building, and determining the environmental comfort index according to the temperature and humidity in the sanitation building.

[0165] Wherein, the expression of the gas pollution index is:

[0166] ,

[0167] is the odor pollution index, For the The concentration of the odor collected, For the The time interval corresponding to the data collection is The odor pollution index is calculated to evaluate the impact of sanitation buildings on the surrounding environment. The higher the odor pollution index, the more serious the environmental pollution caused by the garbage dump in the sanitation building. It can be determined by obtaining the average odor concentration of sanitation buildings in normal operating conditions during the same period, such as the average odor concentration of sanitation buildings in standard operating conditions at the same time, month or season of the previous year.

[0168] The expression of the harmful gas pollution index is:

[0169] ,

[0170] is the harmful gas pollution index, For the The harmful gas The concentration of the collected For the The standard concentration limit of harmful gases, The number of harmful gas types. The harmful gas pollution index comprehensively reflects the potential risk of at least one harmful gas emitted by sanitation buildings to the surrounding environment and residents' health. Since the impact of harmful gases on the environment or human health has a certain irreversible risk of damage, The maximum concentration of specific harmful gases or the set ratio of maximum concentrations can be determined according to relevant environmental safety standards to prevent harmful gases from causing irreversible effects on the environment or human health.

[0171] The expression of the environmental comfort index is:

[0172] ,

[0173] is the environmental comfort index, is the first coefficient, is the second coefficient, and The specific coefficient value can be set according to the impact of temperature and humidity on the environment in the area where the sanitation building is located. is the temperature inside the sanitation building, It is the center value of the reference temperature range in standard sanitation buildings. The reference temperature range in standard sanitation buildings is 20℃-25℃. is the temperature standard deviation, is the humidity inside the sanitation building, It is the center value of the reference humidity range in standard sanitation buildings. The reference humidity range in standard sanitation buildings is 40%-60%. is the humidity standard deviation.

[0174] Step S803, based on the comparison between the above odor pollution index, harmful gas pollution index and environmental comfort index and the set threshold value, specific maintenance equipment in the sanitation building is started.

[0175] When the odor pollution index exceeds a first threshold, an odor purification work order is generated, and the odor purification work order is sent to an odor purification system in a sanitation building;

[0176] When the harmful gas pollution index exceeds a second threshold, a harmful gas adsorption work order is generated, and the harmful gas adsorption work order is sent to a harmful gas adsorption system in a sanitation building;

[0177] When the environmental comfort index exceeds the third threshold, a garbage compression work order is generated and sent to the garbage compression equipment in the sanitation building.

[0178] The specific expression of the efficiency index of the built-in garbage compactor in the sanitation building is: , is the efficiency index of the garbage compactor, For the The amount of garbage compressed and processed For the Secondary compression ratio (ratio of volume after compression to volume before compression), For the The energy consumed in the compression process. The efficiency index of the garbage compactor reflects the garbage processing and compression effect of the garbage compactor under the consumption of a certain amount of energy.

[0179] In addition, for the garbage transfer equipment of the present embodiment, the transferable information of the garbage transfer equipment recorded in the sanitation building control center also includes a garbage transportation efficiency index, and the specific expression of the garbage transportation efficiency index is: ,in, is the waste transportation efficiency index, is the number of trips of the garbage transfer equipment, is the rated load of the vehicle, For the The full load rate of each transportation. The garbage transportation efficiency index is used to evaluate the overall efficiency of the transferable equipment in the garbage transportation process. The higher the garbage transportation efficiency index, the better the transportation efficiency.

[0180] The urban sanitation building monitoring system based on big data technology, the urban sanitation building monitoring method based on big data technology proposed in this embodiment is equipped with multiple environmental detectors at the sanitation building, which are used to feedback the concentration of various pollutants and the humidity of the area where the sanitation building is located. Combined with the influence of humidity, real-time wind speed and wind direction in the area where the sanitation building is located, the improved Gaussian plume model is used to obtain the pollution degree of various pollutants to the area where the sanitation building is located; and under the comprehensive consideration of the real-time weights of various pollutants determined by the attributes of the area where the sanitation building is located and the number of people in the area, the specific environmental impact index of the sanitation building is obtained by combining the pollution degree of various pollutants to the area where the sanitation building is located, and the corresponding sanitation building maintenance work order is generated according to the environmental impact index. The improved Gaussian plume model is introduced to take into account the influence of environmental humidity, wind direction and wind speed on actual pollutant emissions, and further combine the number of people in the area to determine the influence of pollutant emissions. Compared with the prior art that only maintains sanitation buildings based on parameters collected by environmental detectors, the environmental factors and personnel influence factors of the area where the sanitation building is located are comprehensively considered, and the health or experience of residents is moderately measured in the management of urban sanitation buildings, so as to improve the quality of sanitation building detection data and management.

[0181] Furthermore, in this embodiment, the consideration of the average impact of various pollutants on the regional population not only sets the real-time weights of various pollutants in combination with the regional attributes of the sanitation building, but also introduces changes in the population size in the region, adjustments to regional attributes, and the content of complaints received about sanitation buildings to timely correct the real-time weights of various pollutants, so that the environmental impact indicators are closer to the actual characteristics of human activities or regional activities, thereby improving the credibility of the environmental impact indicators.

[0182] Furthermore, in the process of determining the specific maintenance work order for the sanitation building, this embodiment not only considers the capacity of the garbage to be transferred and the loading capacity of the transferable equipment, but also combines the shortest path time for the transferable equipment to reach the sanitation building and the maintenance urgency determined by the sanitation building based on the complaint content. In the process of sanitation building maintenance, the opinions of surrounding residents are comprehensively considered to improve the efficiency of garbage treatment in the sanitation building, while improving the satisfaction of surrounding residents with the sanitation building and reducing the occurrence of NIMBY effect.

[0183] In addition, based on the above information, in addition to maintaining sanitation buildings through garbage disposal equipment and garbage transfer equipment, the above information can also be fed back to the urban management system to provide data support for changes in urban area attributes, adjustments to public buildings or residential buildings in urban areas, and site selection of sanitation buildings in urban management.

[0184] For example, when the urban area attributes need to be adjusted, the historical comprehensive score of the sanitation building can be used as a reference value for the regional attribute adjustment; when the number of times the historical first maintenance index or the second maintenance index of the sanitation building is lower than the maintenance limit exceeds the threshold, it means that the environmental monitoring data of the sanitation building is inconsistent with the current regional attributes. At this time, if the regional attributes are adjusted, they can be adjusted to the regional attributes with a lower maintenance lower limit for the sanitation building, such as from a residential area to an industrial area; when the proportion of the historical first maintenance index or the second maintenance index of the sanitation building higher than the median of the current area reaches the set threshold, it means that the environmental monitoring data of the sanitation building is better for the current regional attributes. At this time, if the regional attributes are adjusted, they can be adjusted to the regional attributes with a higher maintenance lower limit for the sanitation building, such as from a residential area to an educational area.

[0185] When a new sanitation building needs to be sited, we can refer to the historical comprehensive scores of each area and combine the historical public opinions on sanitation buildings in each area on the public opinion platform to select areas that have less impact on surrounding residents or that are in urgent need of adding new sanitation buildings as alternative addresses.
