Description

{SYSTEM FOR PROVIDING CONSTRUCTION WASTE RECYCLE SERVICE}

The present invention relates to a system for providing a construction waste recycling service, and provides a system capable of reducing disposal of surplus materials, environmental pollution, and the burden on the orderer by collecting, classifying, inspecting, and storing construction waste including surplus materials after materials are delivered and construction is completed.

In the past, unsanitary landfills up to the Nanjido Landfill were converted to sanitary landfills through improvements in related laws and regulations, starting with the first landfill site in the metropolitan area, and there were many improvements. However, fundamentally, direct landfilling of wastes that undergo biochemical decomposition inside the landfill site after landfilling not only wastes resources and energy, but also causes various environmental problems. Accordingly, the government revised the relevant laws and regulations to prohibit direct landfilling of wastes that have not undergone pretreatment for resource and energy recovery from January 1, 2030. This is to prevent waste of resources and energy due to direct landfilling, resolve the problem of securing landfill sites by reducing the amount of landfilling, and reduce environmental hazards due to foul odors and leachate generation. Currently, in many landfills in Korea, various types of wastes are directly landfilled mixed in a partially sorted or unprocessed state, and it will inevitably take time to expand pretreatment facilities.

At this time, methods for distributing building materials and sorting construction waste were studied and developed. In relation to this, prior art Korean Patent Registration No. 10-2267381 (announced on June 22, 2021) and Korean Publication Patent No. 2021-0131478 (published on November 3, 2021) disclose a configuration in which a construction area is determined to supply materials for construction, and a material estimate and a construction estimate are provided when the material and construction unit prices are set, and a configuration in which construction waste generated during the demolition process is loaded onto a conveyor belt for recycling, and the construction waste is sorted and separated along a slope, respectively.

However, in the former case, only the delivery and distribution process for construction is considered, and the possibility of materials remaining after construction and their utilization is not considered. In the latter case, the situation where surplus materials remaining after construction are simply disposed of by mixing them with construction waste is not considered. As the amount of waste incineration and landfill disposal is increasing, local governments and business waste dischargers who dispose of waste through incineration or landfill should bear the burden in order to suppress waste generation and promote waste recycling. Therefore, orderers, including local governments, should manage dismantling waste to minimize incineration and landfill waste, and waste management by orderers has become more important since the introduction of the waste disposal burden system. Accordingly, research and development of a system is required to collect, classify, inspect, and store surplus construction waste after materials are delivered and construction is completed, thereby preventing new products from being landfilled, polluting the environment, and increasing the burden.

One embodiment of the present invention provides a construction waste material recycling service system that delivers materials when an order comes in from a construction company terminal, allocates collection to a recycling terminal when a collection request is received from the construction company terminal after construction is completed, manages the materials through classification, inspection, and registration after collection is completed, and when performing classification, uses vision-based deep learning and a robot arm to increase accuracy and reduce manpower costs, and manages the receipt and shipment of materials in conjunction with a warehouse management system (WMS), a supply chain management (SCM), and an enterprise resource planning (ERP), and manages supply by predicting demand based on order data. However, the technical problems to be achieved by the present embodiment are not limited to the technical problems described above, and other technical problems may exist.

As a technical means for achieving the above-described technical task, one embodiment of the present invention includes a recycling service providing server including a construction company terminal which orders materials in the fields of electricity, communication, and firefighting, and requests collection of construction waste after completion of construction, a recycling terminal which is assigned to collect construction waste, and a receiving unit which receives an order for materials from the construction company terminal, a distribution unit which delivers materials to a construction site of the construction company terminal or a delivery location designated by the construction company, an allocation unit which receives a request for collection of construction waste from the construction company terminal and assigns collection to a recycling terminal, and a storage unit which registers and classifies the construction waste and creates a database when the construction waste is collected at the recycling terminal.

According to any one of the problem solving means of the present invention described above, when an order is received from a construction company terminal, materials are delivered, and after construction is completed, when a collection request is received from the construction company terminal, collection is allocated to a recycling terminal, and after collection is completed, the materials are managed through classification, inspection, and registration, and when performing classification, vision-based deep learning and a robot arm are used to increase accuracy and reduce manpower investment costs, and the receipt and shipment of materials are managed in conjunction with a WMS (Warehouse Management System), SCM (Supply Chain Management), and ERP (Enterprise Resource Planning), and the supply can be managed by predicting demand based on the order data.

FIG. 2 is a block diagram for explaining a recycling service providing server included in the system of FIG. 1, and FIGS. 3 and 4 are drawings for explaining an example in which a construction waste material recycling service according to one embodiment of the present invention is implemented.

Referring to FIG. 2, the recycling service providing server (300) may include a receiving unit (310), a distribution unit (320), a collection unit (330), a storage unit (340), a WMS unit (350), an inspection unit (360), a demand prediction unit (370), a disposal request unit (380), an automatic classification unit (390), and a control unit (391).

When the recycling service providing server (300) according to one embodiment of the present invention or another server (not shown) operating in conjunction with it transmits a construction waste recycling service application, program, app page, web page, etc. to at least one construction company terminal (100), at least one robot arm (400), and at least one recycling terminal (500), the at least one construction company terminal (100), the at least one robot arm (400), and the at least one recycling terminal (500) may install or open the construction waste recycling service application, program, app page, web page, etc. In addition, the service program may be driven on at least one construction company terminal (100), at least one robot arm (400), and at least one recycling terminal (500) by using a script executed in a web browser. Here, a web browser refers to a program that enables the use of web (WWW: World Wide Web) services and receives and displays hypertext written in HTML (Hyper Text Mark-up Language), and includes, for example, Chrome, Edge (Microsoft Edge), Safari, Firefox, Whale, UC Browser, etc. In addition, an application refers to an application program on a terminal, and includes, for example, an app running on a mobile terminal (smartphone).

Referring to FIG. 2, the receiver (310) can receive an order for materials from a construction company terminal (100). The construction company terminal (100) can order materials in the fields of electricity, communication, and firefighting. The company of the applicant of the present invention is a company that distributes materials in the fields of electricity, communication, and firefighting as shown in FIGS. 4j and 4k, and is establishing a distribution sales network for these materials. One embodiment of the present invention provides a service of receiving an order for materials from a construction company terminal (100) as shown in FIG. 4l, delivering the materials, collecting construction waste materials from a construction site where construction has been completed after delivery, and classifying, inspecting, and storing the construction waste materials. At this time, when ordering, the materials are for construction, but when collected, even if they are new products, they are often mixed with construction waste materials and buried, so they are named construction waste materials. However, in reality, the construction waste materials collected in one embodiment of the present invention mean surplus inventory.

The distribution department (320) can deliver materials to the construction site of the construction company terminal (100) or to the delivery location designated by the construction company. At this time, the person in charge of the recycling terminal (400) may be in charge of only collection, but may also be in charge of distribution and logistics, so he or she may be assigned work from the distribution department (320) to deliver materials to the delivery location. At this time, the distribution department (320) may request the person in charge to minimize construction waste by preventing excessive packaging inside boxes and collecting boxes when providing materials.

The collection unit (330) can receive a request for collection of construction waste materials from the construction company terminal (100) and assign collection to the recycling terminal (500). The construction company terminal (100) can request collection of construction waste materials after completing construction. The recycling terminal (500) can be assigned collection of construction waste materials. There are always materials left over after construction. For example, after connecting communications or electricity, there are many cases where several meters or tens of meters of various cables or wires are left over, and in addition to these, there are many cases where various materials are left over, such as PVC conduit, PVC conduit waterproofing pipe, steel box, PVC buried box, communication cable, ACF cable, wiring device, residential distribution board and circuit breaker, telephone, communication, broadcasting, grounding terminal box, TV amplifier box, and grounding material. Each construction site or construction company has one or more material warehouses as in Fig. 4a to manage materials, but they are not managed systematically and just pile up, so that even though there is stock, the process of not knowing what is in stock and purchasing it again is repeated, and since moisture management is not done properly, they rust or cannot be reused, and each orderer must bear the cost of processing such piled up materials and construction waste according to the waste disposal burden system. Accordingly, in one embodiment of the present invention, such surplus materials are collected after construction is completed, classified and inspected, and materials that have passed inspection are managed as new products so that they can be resold thereafter or notified to each construction company so that they can be sold.

Also, if this is collected and this data is recorded, a dataset for [construction scale-material type-material order quantity-material collection quantity] can be prepared, and if this is built into big data, the construction company can predict how much will be left when placing an order later, so a guideline can be provided to order less than this, or if there is no intention to purchase this material more cheaply from another construction company because there will be leftovers, or a platform can be provided that connects the original orderer and the subsequent orderers so that both can benefit by providing a win-win situation by extracting construction companies that will use the same materials and providing a deal right away.

The storage unit (340) can register and classify construction waste materials and create a database when construction waste materials are collected at the recycling terminal (500). Materials in the fields of electricity, communication, and firefighting supplied and distributed by the applicant's company are databased with product names, unique identification codes, photos, etc., as shown in FIGS. 4p to 4s, for example, [product name-unique identification code-specification-size-photo]. At this time, when construction waste materials are collected, the collected construction waste materials pass through a conveyor belt and are photographed by a line camera placed on it, and the construction waste materials are distinguished using a vision-based deep learning model, i.e., an object detection model, in the photographed image, and the product name and unique identification code are extracted, and the robot arm (400) described below can be used to pick up and place the materials so as to load them into a preset box or space.

<Object Recognition>

Object Detection is to analyze a given image and identify the location and class of a specific object when a specific image is input. The object detection algorithm must first find the location of the object in the image (Localization), and then classify the object at that location. Various methods have been attempted to perform this, but recently they have been narrowed down to single-stage (1-Stage) detection methods and two-stage (2-Stage) detection methods.

The single-step detection method performs location detection and classification simultaneously for all areas, while the two-step detection method performs rough location detection and then performs classification on the selected candidates. Since the single-step detection performs location detection and classification of objects in all areas simultaneously, it is fast, but has a disadvantage in that its accuracy is slightly lower than that of the two-step detection method. On the other hand, the two-step detector performs object location detection and classification sequentially, so its accuracy is relatively high, but its speed is low. In this case, in one embodiment of the present invention, since construction waste materials passing by quickly on a conveyor belt must be classified, the single-step detection method is used rather than the two-step detection method that identifies the detailed type. Of course, the use of the two-step detection method is not excluded.

<SSD>

For example, you can use a model that can detect human faces and objects using the SSD (Single Shot Detector) model, which is one of the deep learning frameworks of the single-step detection method, and OpenCV. SSD (Single Shot Detector) works well even in low resolution, so it basically gives an input image with a size of 300x300, but here, it can be input with an image size of 200x200 or smaller for faster processing speed. The input image is used as the base network of the VGG-16 model, and the class score of the bounding box is obtained through each corresponding feature map. The output from each layer of the convolutional neural network and each feature map apply a convolution operation with a 3x3x3 sized filter, and calculate the intersection over union (IOU) threshold between boxes to find a face by considering only boxes that are more than N, and then find the location of the eyes. Of course, it is obvious that single-step detection methods such as YOLO can also be used and that it is not limited to SSD.

The WMS (Warehouse Management System) section (350) registers and classifies construction waste materials and manages them by WMS after creating a database, and when an order is received from a construction company terminal (100), it processes the order and updates the WMS. At this time, WMS is literally a system for warehouse management. Its basic purpose is to accurately manage the inventory managed by workers or managers working in a logistics center or warehouse. In other words, it refers to a system that manages inventory in a warehouse so that it can be easily managed or shipped, manages inventory in the best condition so that it can be shipped smoothly without damaging, losing, or abandoning the inventory, and executes, manages, and monitors the process of shipping the inventory quickly and accurately at the desired required time.

Since WMS is a system designed to manage inventory well, it cannot operate independently and is closely interrelated with other systems. Order information from the sales system is entered and transmitted to the shipment information of WMS, and the results of the shipment processing and completion are reflected back to the accounting, sales, and production systems, and an interface with other systems is essential. WMS should be expressed in various forms, such as not only simple product storage, but also management of all activities within the warehouse, such as order and product flow, optimization of receipt and picking, increased space utilization efficiency, optimization of equipment and human resources, real-time provision of information on logistics flow, and support. Therefore, all of this information should be databased and provided in real time as necessary, and companies should enable decision-makers such as management to make quick decisions for efficient and smooth business activities.

① Save The ability to safely store and maintain items ② Supply and demand Adjust for the time difference between production and consumption of goods ③ Price A function that seeks price stability by adjusting the supply and demand of goods. ④ Connection In addition to the function of connecting each factor of logistics, it also has the function of distribution processing, trading agency function, and economic transportation cost reduction function. ⑤ Credit Ability to process customer orders in a timely manner through safety stock

<Automatic warehouse system>

ASRS (Auto Storage and Retrieval System), which is an automated warehouse system, is a system that automatically processes the entire process from receipt to shipment. It refers to a system that automatically processes receipt, shipment, and inventory management by linking automatic transport equipment such as stacker cranes, automated guided vehicles (AGVs), lifts, and conveyors, and control computers that control them by introducing an information system in warehouse operation so that the entire warehouse operation can be automated. When construction waste materials are sorted by a robot arm (400) on a conveyor belt, inspection is performed by a person, and then an ASRS can be constructed so that the entire process from receipt to shipment can be performed by the automatic warehouse system. The reason why inspection is performed by a person is that there may be materials that were not properly sorted by the robot arm (400), and even if they are properly sorted, it is necessary to check whether electricity or communication is flowing properly or operating properly. Even if there is a malfunction, the machine checks at each manufacturer's factory, but the applicant's company is a logistics specialist, so it is realistically impossible to have all of these machines, so a person can be brought in for a short while and then the warehouse can be managed by ASRS again. Of course, if economies of scale and economies of scope are achieved, a device that checks for malfunctions in each material can be used to automatically inspect, so automatic inspection is not completely ruled out. In this case, comparing an automatic warehouse and a manual warehouse can be organized as shown in Table 2 below.

Manual warehouse Automatic warehouse function Cargo-box products, pallets
Storage and receipt/shipment Cargo-box products, pallets
Storage and receipt/shipment facility Rack, Forklift Rack, Stacker Crane Minimum height 2m 10m Maximum height 13m 40m Loading load Up to 1.5 to 2 tons Up to 10 tons depending on design Incoming/Outgoing Speed commonly speed Storage efficiency lowness height Product and delivery information Save all information manually All information is saved automatically
Chapter, Integration with ERP Construction period 1~2 months 6 to 7 months or more depending on the size Initial investment cost Very cheap Very high Labor cost input relatively high relatively low

In the module for receiving, you can perform item-specified receiving, location-specified receiving, and item-identified receiving, and in the module for shipping, you can perform item-specified shipping and location-specified shipping. In ASRS monitoring, you can check the error status of racks and equipment, and in the inventory status inquiry, you can check various receipt/disbursement performance, inventory performance, etc. At this time, you can monitor various KPIs (Key Performance Indicators) of the logistics warehouse in the simple execution stage, analyze or simulate this information to evaluate or improve the current warehouse, and further perform the warehouse optimization system (WOS), which is a field that maximizes the operational efficiency of the warehouse. As one area of warehouse optimization, you can monitor the KPIs of the warehouse, design the warehouse layout, model various facilities, perform simulations, and analyze the results. Based on the analyzed data, you can rearrange the products loaded in the warehouse, or in the case of an automatic warehouse, readjust the installation location or quantity of conveyors or stacker cranes to maximize the utilization rate of the facilities and optimize the warehouse performance.

Inspection department (360) can inspect construction waste materials at an inspection terminal when construction waste materials are received, and if the inspection results are normal, the construction waste materials can be registered at the inspection terminal. At this time, the inspection can be conducted by an actual person as described above.

The demand forecasting unit (370) manages orders received from construction company terminals (100) as ordering data, and analyzes and predicts the demand for materials distributed to construction companies based on the ordering data. At this time, a prediction can be made using a time series analysis model such as LSTM based on the ordering data, or a method can be used to analyze demand for construction materials based on big data, input the characteristics of the applicant's client company, and then predict how much material the client company will order.

<Big Data-Based Demand Forecasting>

Domestic construction material market forecasts are published by research institutes on a yearly basis for major materials, but regional market forecasts are not published, so material companies are not able to utilize and effectively use regional market forecasts. Although construction companies need to know where and how much construction materials will be in demand in real time for decision-making, most of them are confirmed through information from construction officials. Therefore, it is possible to build big data by segmenting construction and material demand by region, type of construction, and material for construction companies, subcontractors, and construction material suppliers, and to provide a service that shows construction material demand forecasts in real time by accumulating data.

In the past, with regard to demand forecasting of construction materials, mid- to long-term demand for cement, ready-mixed concrete, rebar, and aggregate was estimated by considering macroeconomic changes and construction activities. However, recently, demand for major construction materials is forecasted by focusing on construction completion costs by type of work, utilizing construction commencement area data. However, since such demand forecasting of construction materials does not have a section for short-term forecasting that can forecast demand for major materials by month and region using building permit information, one embodiment of the present invention can provide a model that allows construction-related companies to forecast demand for construction materials in the short term. For example, a construction material demand forecasting model based on a standard schedule utilizing big data such as building construction industry GDP, building permit information, and housing permit information can be used.

The logic for predicting the construction scale and material demand for building permits and commencement data is as follows: first, the total floor area and expected start date for each project are identified from the building permit information, the total construction cost for each project are estimated, the construction cost by type is estimated, the material quantity by material is identified from the total floor area for each project, and the total construction cost and material quantity demand by project can be predicted. This can predict the total monthly construction cost and material quantity demand through past permit data based on the prediction time. In addition, the permit and commencement performance using the building construction industry GDP from the building permit and commencement statistics can be predicted, the order quantity by use and structure can be estimated, and the monthly construction cost and material quantity demand can be predicted by predicting the expected future permit order quantity at the prediction time. In this case, the total monthly construction cost (including by type) and the demand for major materials can be predicted.

In addition, a system can be established to collect basic data for forecasting construction material demand. This basic data can be used for public data on building construction GDP (Statistics Korea), building permit & construction start performance information (Seumteo), new construction unit price information (Korea Real Estate Board), and standard construction schedule information. When forecasting building construction GDP, the forecast setting value can be subdivided according to the detailed standard construction schedule, that is, whether it is office building construction materials, apartment construction materials, or neighborhood construction materials, etc., and the information on the projection by type of work can be used to forecast the demand for materials according to the amount and period of each project.

The disposal request unit (380) can request a collection company corresponding to the type and amount of construction waste to be disposed of when the recycling terminal (500) requests disposal of construction waste. The person in charge goes to the construction site and collects the waste according to the collection request, but the materials may not be the ones he or she has supplied, and waste materials that should be landfilled may be mixed in. In this case, the person in charge of the recycling terminal (500) can collect only the construction waste corresponding to the surplus materials, and call a truck driver who will actually landfill the rest and request landfill.

The automatic sorting unit (390) can operate a robot arm (Robot-Arm, 400) to pick up and place the classified construction waste materials by taking pictures of the construction waste materials from a camera installed on a conveyor belt when construction waste materials are received, classifying the construction waste materials based on the pictures taken, and picking up and placing the classified construction waste materials. At this time, the picking up and placing can include a Reaching step in which the robot arm (400) reaches an object, a Lifting step in which the object is lifted, and a Placing step in which the object is moved to a target position. At this time, the Placing step can be considered as a type of Reaching in which the object is held and the target position is reached. Therefore, in one embodiment of the present invention, the picking up and placing can be divided into a first Reaching task in which the object is reached, a Grasping task in which the object is held and the second Reaching task in which the object is held and the target position is reached. At this time, the first Reaching task and the second Reaching task are performed by agents learned through Soft Actor-Critic, a reinforcement learning, and the Grasping task can be implemented through simulation-based control. The learning and testing process can be performed through Robosuite, a framework for developing and testing robot control algorithms, and the MuJoCo engine, which can simulate physical interactions between robots and objects, but is not limited thereto.

Here, SAC (Soft Actor-Critic) is a reinforcement learning algorithm that learns probabilistic policies in a continuous action space. SAC introduces the concept of maximum entropy to improve the agent's exploration ability. Through this, the agent establishes an optimal policy that can maximize reward and entropy through experience with more diverse actions.

The control unit (391) can connect the air conditioning equipment of a warehouse where construction waste materials are stored to IoT, monitor the air conditioning data of the air conditioning equipment, and control the operation of the air conditioning equipment.

Hereinafter, the operation process according to the configuration of the recycling service providing server of the above-described Fig. 2 will be described in detail with reference to Figs. 3 and 4 as examples. However, it will be obvious that the embodiment is only one of various embodiments of the present invention and is not limited thereto.

Referring to FIG. 3, (a) when an order comes in from a construction company terminal (100), the recycling service providing server (300) performs delivery, and (b) when a collection request comes from a construction company terminal (100) or the recycling service providing server (300) confirms that construction is completed, it automatically assigns a collection task to a recycling terminal (500), and when the person in charge completes the collection, it places it on a conveyor belt so that the robot arm (400) can identify, classify, and classify each construction waste material, i.e., surplus material, based on a vision. The surplus material classified in this way is managed in conjunction with each ERP, CRM, etc. from receipt to delivery through WMS and further ASRS. At this time, (c) before receipt, whether it is operational can be inspected at each inspection terminal (not shown) and then information on the material can be registered in the database. In other words, after all materials are registered in the database, the inspection results can be further updated, or only those that are operational after inspection can be received and registered in the database. This may vary depending on the embodiment and is not limited to one. In addition, the recycling service provision server (300) can predict demand based on previously ordered data and various construction permits, and can manage the supply chain and warehouse through this.

According to one embodiment of the present invention, the platform considers the reality that each specialized construction company has a material warehouse as shown in Fig. 4a, but surplus materials are not managed well, and even surplus materials are landfilled together with construction waste even though they are new, and that in order to landfill waste, responsibility for preprocessing and landfill must be taken according to the recently implemented orderer burden principle. Since the applicant of the present invention has the distribution know-how of construction materials and is establishing a comprehensive logistics service, in order to solve the surplus materials as shown in Fig. 4c, rather than ending with ordering and supply as shown in Fig. 4d, the remaining materials are collected, classified, inspected, and stored again after construction is completed, thereby reducing the burden on each construction company and not harming the environment. The platform of the present invention has the differences as shown in Fig. 4e, and can expect the effects as shown in Fig. 4f. One embodiment of the present invention can enter the market as shown in Fig. 4h based on the model as shown in Fig. 4g. Currently, the applicant's company has an investment plan as in Fig. 4i. The applicant is strengthening quality by organizing the purchase-shipment process as in Fig. 4m and planning and preparing a surplus inventory storage service as in Fig. 4n and Fig. 4o.
