Green City Smart Operation: Web 3D Waste Classification GIS System

foreword

Thank you to all those who contributed to the epidemic in Shanghai, and pray that the epidemic in Shanghai will be cleared as soon as possible. Come on, China, come on Shanghai!

It has been more than two years since the implementation of the "Shanghai Municipal Waste Management Regulations". Shanghai citizens have basically developed the habit of practicing green and low-carbon concepts and actively participating in the classification of household waste. The average amount of recyclables is above 9,000 tons, and the daily average of recyclables is kept above 7,000 tons. "Adopting a fixed-point system", "implementing the upgrading and transformation of waste disposal points", and "carrying out extensive publicity and mobilization" are the main reasons for the success of Shanghai's domestic waste classification work.

Tupu software visualization combined with HT for Web GIS can realize remote monitoring of garbage disposal points and dynamic positioning of garbage transportation vehicles, urge residents to classify garbage by intelligent means, and arrange transportation vehicles in an orderly manner.

Tupu software HT supports the loading of different map tile services or data, 3DTiles format data of aerial oblique photography real scenes, and different GIS data such as urban buildings. Seamless integration and other technical advantages, in the GIS system, a variety of visual display of massive POI data, traffic flow data, planning data, status data and so on.

System analysis

City overview

Garbage disposal follows the criteria of reduction, harmlessness, resource utilization, capital saving, land saving and residents' satisfaction. For example, in order to facilitate transportation and reduce costs, compression treatment is often performed; in order to recover useful substances, crushing treatment and sorting treatment are often required. If incineration or landfill is used as the final disposal method, appropriate crushing, sorting, etc. of the garbage should be done first to make the disposal more effective.

By connecting the smart monitoring data and sensor equipment data to the large visualization screen of the Tupu software, you can view the total amount of garbage in the city and the garbage collection rate on the day in the garbage classification and treatment control center. Through the visualization of information statistics on the large screen, combined with big data, cloud computing and other technologies, the social cost of waste management can be obtained, and the refined management, cost reduction and efficiency increase can be realized.

Waste incineration power generation

Sanitary landfill, high-temperature composting and incineration are widely used methods of garbage disposal today, but in the process of garbage incineration, in addition to secondary environmental pollution, it will also cause waste of resources and energy. Therefore, waste incineration and power generation can be used for waste treatment. In the context of carbon peaking and carbon neutrality goals, exploring the green value of the waste incineration power generation industry and alleviating the negative sentiment in the industry caused by the decline of renewable energy subsidies is conducive to ensuring the long-term compliance of the industry.

According to the relevant plans of the "14th Five-Year Plan", by the end of 2025, the national waste incineration processing capacity will reach about 800,000 tons per day. By then, the national waste incineration power generation can save 26 million tons of standard coal and reduce carbon dioxide emissions by 50 million tons every year. An average of 120 million tons of carbon dioxide is also reduced annually by replacing sanitary landfills.

Harmless treatment of garbage

Waste incineration power generation is expensive and has a small amount of treatment, so it is not the mainstream waste treatment method. Therefore, domestic waste treatment should avoid and reduce the generation of domestic waste from the source as much as possible, and the generated domestic waste should be classified and recycled as much as possible to achieve source reduction.

Refinement of community governance requires not only human touch, but also technology, and garbage can be sorted and recycled through robotic arms.

Realize the visualization of garbage disposal data through Hightopo, allowing operation and maintenance personnel to conduct comprehensive analysis to ensure that domestic garbage is treated and disposed of harmlessly. According to the "Shanghai 2021-2023 Three-Year Action Plan for Ecological Environmental Protection and Construction", in 2023, the city's domestic waste incineration capacity will reach 29,000 tons/day, the wet waste treatment capacity will reach 9,000 tons/day, and the domestic waste emergency landfill capacity will reach 29,000 tons/day. up to 5000 tons/day. The compost is processed on site by biotechnology, and each ton can produce 0.6~0.7 tons of organic fertilizer.

The amount of garbage thrown out on the day

Disposing of hazardous waste, recyclable waste, wet waste and dry waste can improve the utilization rate of waste recycling and save manual sorting time. In order to urge people to place garbage accurately, streets, communities, and outsourcing service providers can use Tupu software to visualize the multi-screen interconnection of large screens, computer clients, and mobile phone clients to form a three-level supervision mechanism. Dirty issues, clean up as required.

Waste treatment efficiency and recycling volume statistics

1 ton of waste plastic can be recycled into 600 kg of unleaded gasoline and diesel. Recycling 1,500 tons of waste paper can avoid deforestation for the production of 1,200 tons of paper. Therefore, garbage sorting and recycling is not only environmentally friendly, but also saves resources.

Tupu software HT visualization uses rich charts, graphics and design elements to display relatively complex and abstract data in a more intuitive and understandable form in a visual way, which is convenient for the efficient management of operation and maintenance personnel, and does not require complex forms such as manual calculation. Operation and maintenance analysis of garbage disposal.

Delivery volume by district on the day

The large-screen visualization of Tupu software can access real-time data of smart devices, and display the delivery volume and delivery times in different areas such as Huangpu District, Xuhui District, and Changning District through different types of charts.

Zoning Statistics

Accurate restoration of Shanghai map is realized through Hightopo self-developed engine combined with GIS. A GIS engine capable of accurate synchronization with 3D scenes. The garbage classification situation in 16 districts in Shanghai was counted separately and checked in a targeted manner. In the second half of 2021, the 16 districts and 220 streets and towns in Shanghai will achieve an "excellent" level of domestic waste classification effectiveness. Among the districts, Jiading District and Yangpu District ranked the top two in the evaluation results.

Quantity in each district on the day

Recyclables mainly include five categories of waste paper, plastic, glass, metal and cloth. Dry garbage includes bricks and ceramics, muck, toilet waste paper, paper towels and other difficult-to-recycle wastes, dust, and food bags (boxes) in addition to the above-mentioned types of garbage. Wet garbage includes food waste such as leftovers, bones, vegetable roots, and fruit peels. Tupu software HT can count the amount of delivery in different cells in the area, and distinguish between wet garbage and dry garbage by different colors. Grasp the key links, start with the removal of barrels and points in the community, guide and supervise the classification and release of domestic waste, and earnestly do a good job of reducing the amount of domestic waste at the source, classifying distribution, classifying collection, and classifying transportation.

Delivery accuracy

Different management modes such as manual supervision, manual inspection supervision, manual video supervision and intelligent supervision can be adopted to ensure the effect of classified delivery. The intelligent monitoring technology with AI recognition function is used to continuously monitor the classified placement points. Through pressing intelligent supervision and diversion intelligent supervision, the video intelligent identification of events such as "small package of garbage", "garbage overflowing", "environmental quality of delivery point", "unclassified delivery" can be captured, and violations can be captured and sent to relevant personnel. It can be superimposed to automatically trigger voice warning reminders and other functions for violations that occur at the delivery point. For example, 68 monitoring equipments have been installed at the fixed bucket station in the bungalow area on Gymnasium Road Street, which can be connected to Hightopo for real-time viewing, remote playback, and multi-screen interconnection to promote the refinement and precision of garbage classification.

Violation record

Through various intelligent monitoring measures, the method of violation and the name of the community are counted separately, and then the video is shot at the delivery point for punishment. As a component library based on HTML5 standard, Tupu software HT can seamlessly integrate various multimedia functions of HTML5, supports the integration of various video resources to form a unified video stream, and can mark camera objects on 2D and 3D situation maps and associate their video signals source, and retrieve the corresponding surveillance video through scene interaction.

Residents who have been reminded for many times and still put in the mix shall be reported to the law enforcement department for administrative punishment according to law, so as to improve the awareness rate, accurate delivery rate and kitchen waste classification rate of garbage classification. In Shanghai, there will be fines and administrative penalties for failing to classify garbage and not placing it in designated trash cans. If the individual does not put the garbage into the classification, the maximum fine is 200 yuan, and the maximum fine for the unit is 50,000 yuan. However, punishment cannot solve the problem at the source. We should strengthen publicity and guidance, and vigorously popularize the knowledge of domestic waste classification through newspapers, television, Internet, light box advertisements, leaflets and other media, and improve citizens' awareness and participation in domestic waste classification.

Transportation

The classified and recycled garbage should be classified for transportation and classified as resources. Hazardous garbage contains heavy metals that are harmful to human health, toxic substances, or wastes that cause actual or potential harm to the environment. Including batteries, fluorescent tubes, light bulbs, mercury thermometers, paint buckets, some household appliances, expired medicines and their containers, expired cosmetics, etc. These wastes are generally recycled separately or disposed of in landfills.

The garbage transportation system based on HTML5 WebGL and GIS technology uses HT for Web GIS to realize the positioning of different types of transportation vehicles, emphasizing real-time and dynamic. Combined with the Beidou system, the number and location of different types of garbage trucks can be marked on the map and distinguished by different colors and shapes.

The intelligent sanitation system, relying on the Internet of Things technology and mobile Internet technology, conducts real-time management of the whole process of people, vehicles, things and things involved in sanitation management.

Job mileage statistics

Tupu software uses area charts to display the operating mileage of different vehicles on different days. For transportation vehicles with very short transportation mileage within a few months, another arrangement can be made.

The statistics of the collection and transportation volume of various types of garbage on the day and the completion rate of the collection and transportation volume of each district on that day can bring historical data reference for garbage classification and realize the optimal configuration of garbage transportation vehicles.

Summarize

Incorporate garbage classification into the "one-network unified management" platform, adopt mature technologies to build waste classification management application scenarios, realize closed-loop management of waste classification issues, and implement "one-network unified management" for daily inspections of waste classification, management of key groups, and tracking of penalties for violations. We will further improve the regular and fixed-point classification delivery system, carry out special rectification actions for small-package garbage, deepen the transformation of delivery points to facilitate the people and benefit the people, and promote the "one network unified management" to enable the daily management of waste classification, and improve the appearance of the classification environment.

According to the "14th Five-Year Plan for the Development of Urban Domestic Waste Classification and Treatment Facilities", by the end of 2025, the national domestic waste classification collection and transportation capacity will reach about 700,000 tons per day, which basically meets the requirements for the classification and classification of urban domestic waste at the prefecture level and above. Demand for transshipment and classification treatment; the national urban domestic waste incineration capacity reaches about 800,000 tons/day.
