Description

A system for providing care services for each product life cycle {SYSTEM FOR PROVIDING PRODUCT LIFE-CYCLE MANAGEMENT SERVICE}

The present invention relates to a system for providing care services for each product life cycle, and provides a platform that can provide a total care service from product purchase, installation, maintenance, repair, transfer, second-hand trading, quarantine and waste treatment.

With the development of ICT technology, each industrial field is becoming intelligent and convergence due to the 4th industrial revolution. In particular, AI-based smart housing, which responds to the diverse needs of residents and relieves residents’ inconveniences by applying AI-based smart technology to housing, provides housing services, meaning various types and intangible services that support the lives of residents in houses. there is. The domestic smart housing market is accelerating competition for leadership in the smart housing business through alliances between the three major telecommunication companies and construction companies due to the development of home appliances, but the main application fields are healthcare and elderly housing, and models linked to hospitals are also presented. . Even in this highly advanced present, there are fields that are not automated and require the input of manpower. Each home appliance or IoT device is installed, relocated, or repaired, or maintenance such as cleaning and sterilization is performed.

At this time, a platform that connects users and drivers for purchase and installation of air conditioners or remotely maintains them has been researched and developed. In this regard, Korea Patent Registration No. 10-2063904 (announced on January 08, 2020) and In Korea Patent Registration No. 10-0851011 (notice on August 12, 2008), when an air conditioner installation quotation is requested from a user terminal, a quotation is collected from at least one engineer's terminal and transmitted to the user terminal, and any one If you select an estimate, the configuration of sending a work request to the terminal of the engineer who submitted the selected estimate, collecting status data such as installation, operation, and failure of the air conditioner to determine whether the installation is complete, and sending and receiving data to and from the air conditioner when installation is complete Each configuration is disclosed for notifying the connection result after performing the environment setting for this purpose, automatically checking the installation and connection result by sending and receiving data, and performing the maintenance remotely.

However, although the technology for remotely controlling or driving using software is advancing, manual disassembly or assembly of hardware for maintenance such as cleaning still requires human hands as described above. As the number and types of home appliances become diversified and complex, the number of home appliances that each user needs to manage is increasing day by day. As a result, it has become difficult for users to directly manage each home appliance with the updated design, structure and system.

The user terminal 100 may apply for a care service corresponding to any one of purchase, installation, transfer, maintenance, and used transaction of a product, and receive a schedule of the applied care service. Here, the care service may include a quarantine and sterilization service. At this time, the product may include an air conditioner, a washing machine, a dryer, a refrigerator, an air purifier, a bidet, and a mattress, but any product that requires purchase, installation, transfer, maintenance, quarantine and second-hand trading will be possible.

Here, there is a total care service that collects all of the care services. When the user himself/herself in the user terminal 100 registers a home appliance, the user visits the driver terminal 400 at a preset period and maintains it. Management services can be provided, or when a breakdown is received, all services can be provided at the price subscribed to the total care service without separately setting an estimate or price. If a device (not shown) for measuring noise or vibration in the form of a dongle is connected wirelessly or wiredly to each home appliance, the total care unit 320 may After determining whether it is noise or vibration from the home appliance, and analyzing the type of failure that has been previously mapped with the noise or vibration, the driver's terminal 400 may be automatically arranged to visit the user's home.

For example, a few days ago, user A made a thump-thump sound when spinning in a washing machine, so it was determined that it was a horizontal problem and applied for repair to the total care unit 320 through the user terminal 100. When the engineer went directly to the scene, it was found that the type of thump-thump sound was simply not level, and because the drum rotated in a non-horizontal state, the bearings fitted to the drum shaft in the washing machine and the fan belt did not fit tightly. I found out that the shaft itself was broken, and I had to replace not only the fan belt but also the drum. In this case, it is the same as buying a new product, and the product is old and I don't even know if there are parts. So, let's assume that the driver does not recommend repair and advises you to buy a new product. In this case, the general user hears the thump and decides that it is simply the sound of the washing machine shaking, but the expert technician can tell which part is broken just by hearing the sound. Also, in this case, even if the article didn't have to visit, if the user filmed a video and showed it in advance, or if there was a system that can detect it, it may not have been a waste of time.

Accordingly, an embodiment of the present invention is [Dongle->Sound & Vibration Data->AP (Wi-Fi)->Total Care Unit 320->Fault Type->Operation Assignment to Driver Terminal 400] can proceed as a process, and for this purpose, the total care unit 320 may map [sound & vibration data-failure type]. The platform of the present invention provides a total care service as shown in Fig. 4h, and when a member pays a preset amount per year, it provides a total care service to a product that breaks down or requires maintenance. Even if the user does not sign up for repair, an engineer can be assigned immediately to schedule a visit, and the service can be visited first without a call from the customer.

When the total care unit 320 collects the sound data and vibration data of the product through the dongle, if the acceleration sensor and the gyro sensor are further included in the dongle, at least one sensor collects vibration data including XYZ axis vibration. can do. In the case of using an acceleration sensor or a geomagnetic sensor, the vector value of the force applied to the dongle can be known. That is, it is possible to measure in which direction the vibration applied by the dongle is acting, and how much the pattern or intensity is. The total care unit 320 may analyze the collected sound data and vibration data to diagnose the state of the product with a pre-stored artificial intelligence algorithm, and may perform failure prediction based on the diagnosed state of the product.

Here, the total care unit 320 may identify the type of at least one product based on the collected sound data and vibration data. This is because each product generates its own vibration frequency and noise. In addition, in the case of learning, it will be obvious that sound data or vibration data, that is, only one data, can be used in addition to the case where both data are used, that is, not sound data and vibration data. At this time, the pre-stored artificial intelligence algorithm obtains sound data and vibration data in a normal state of at least one product included in the at least one product list, and sound data and vibration data in an abnormal state of at least one product as a learning data set. (Data Set) and may be an algorithm modeled as a training data set.

To this end, the total care unit 320 may, firstly, perform pre-processing including noise removal on the collected sound data and vibration data. This is because, if noise is not removed, the results of data analysis methods that are highly dependent on data will be greatly affected, and eventually the results will be meaningless. At this time, if the noise has already been removed by the total care unit 320, this process may be skipped. Second, the total care unit 320 may apply a pre-mapped and stored weight to the selected product with respect to the sound data collected after the pre-processing. The weight at this time is the weight when the error with the label is the smallest while modeling the artificial intelligence algorithm, and is mapped to an identifier such as each model or product type and stored. Accordingly, when the user terminal 100 searches for a model name or selects a type, a corresponding identifier may be extracted, and a weight mapped to the identifier may be extracted.

Third, the total care unit 320 may convert the collected sound data into a spectrogram image using Short-Time Fourier Trasnform (STFT). In this case, there is a problem in that an error occurs in the frequency analysis technique for an abnormal signal of the Fourier transform, and a method for performing frequency analysis even at the moment when such an error occurs is required. Therefore, STFT is a method of dividing a target signal into frame units in consideration of signal stability and performing Fourier transform while moving a window of a certain size. The formula of STFT in the time domain is STFT(t,w)=∫x(τ-t)e- ^jwτ dτ, and the integral range is from -infinity to +infinity. Here, x(τ) is a signal to be analyzed, and w(τ-t) is a window function. In addition, a spectrogram is a tool for visualizing and grasping a sound or a wave, and the characteristics of a waveform and a spectrum are combined. In the waveform, you can see the change in the time axis, that is, the change in the amplitude axis in the time domain. In the spectrum, you can see the change in the amplitude axis according to the change in the frequency axis, while in the spectrogram, the difference in amplitude according to the change in the time and frequency axes is printed. It is expressed as a difference in density or display color.

Fourth, the total care unit 320 may extract feature data from the converted spectrogram image using a Convolutional Neural Network (CNN). Since the spectrogram is output as an image, as a result, when comparing sound data recorded by a user through image analysis with pre-stored sound data, the image should be used for comparison. At this time, when calculating the similarity between different images, it is difficult to determine the similarity between images through pixel-by-pixel comparison. There is a method of extracting and comparing images, which is deep learning technology, CNN. CNN learns the features of images by itself, can classify images and recognize patterns of images based on the learned features, and is suitable for image processing with a network structure using a convolutional layer. Since an image can be classified based on the features in it, it is used in an embodiment of the present invention. However, it is not limited to CNN, and any method that can distinguish an image and extract its features is possible.

CNN extracts the features of the spectrogram in the form of vectors and can measure the similarity between images by using the extracted features. In one embodiment of the present invention in order to extract the features of the spectrogram, a model using the basic structure of a convolutional neural network consisting of a convolution layer, an activation function layer, and a max pooling layer is used. It can be used, and before measuring the similarity, it is possible to extract and use the feature vector of the spectrogram from the layer before the Softmax layer used to classify the image. Basically, it can be used to measure similarity by extracting features from a model having a CNN with a fully-connected layer and a GAP layer (Global Average Layer) that brings the average value on the feature map. . As another model for measuring the similarity of images, a CNN-based autoencoder model can be used. The encoder is composed of a convolutional neural network structure, and a decoder ( Decoder) may be included. Spectrogram features are extracted from a specific layer of the learned autoencoder model, and the feature vector generated through the GAP layer can be used to measure image similarity. Euclidean distance and cosine similarity can be measured from the image feature vectors extracted through the above three models, and using these, the degree of similarity for each spectrogram, i.e., can be sorted according to the degree of similarity. , by using the sorted order, it is possible to check not only the most similar data for each spectrogram but also the most dissimilar data.

After the feature data for the sound data is extracted, it is necessary to extract the feature data for the vibration data. Fifth, the total care unit 320 converts the collected vibration data to the XYZ axis in the time domain. After performing the restructuring, feature data can be extracted using CNN. The basic concept for this returns to the principle of pendulum movement with respect to the time axis (time domain). The weight on the spring moves up and down as time goes by, leaving a graph while going back and forth between the upper and lower limits based on the central point. Similarly, when the washing machine starts washing or spin-drying while the dongle is connected to the washing machine, the dongle also vibrates due to the vibration of the washing machine. At this time, when using a geomagnetic sensor, a 9-axis sensor, an acceleration sensor, etc., data generation and graph visualization about which direction of the XYZ axis vibration is applied, what is the intensity, and how the pattern is made becomes possible. Since the graph thus generated is also an image, the total care unit 320 may extract feature data for the vibration data using the CNN described above.

After the feature data for the sound data and vibration data measured from the dongle are extracted in this way, the sixth total care unit 320 combines the feature data extracted from the sound data and the vibration data with the previously stored feature data of the selected product. can be compared. For at least one product, characteristic data of sound data and vibration data for normal or abnormal are already learned and stored, and even if it is abnormal, depending on the type of abnormality, for example, whether it is horizontally unstable, foreign matter Characteristic data of sound data and vibration data has already been learned and stored according to whether it is a case of wearing or not a case of normal coupling. Accordingly, when comparing the pre-learned characteristic data with the characteristic data of the sound data and the vibration data measured by the dongle, it is possible to determine whether the characteristic data is normal or abnormal, and in which case the abnormality belongs. In this case, the feature data comparison can use the Euclidean distance as described above as described above.

Finally, the total care unit 320 may select pre-stored feature data having the highest similarity as a result of the comparison. If pre-stored feature data having the highest similarity is selected in this way, a result report may be generated using the selected feature data and transmitted to the user terminal 100 . This is because, in the previously stored feature data, whether normal or abnormal, and when abnormal, the cause of the abnormality, the type of abnormality, and a solution are mapped and stored in advance. At this time, when an AS is requested, the transmission unit 340 connects the nearest AS center based on the location of the user terminal 100 or automatically detects a time available for a visit reservation to the user terminal 100 . While transmitting, the user terminal 100 may be configured to automatically make a reservation when only the time is selected or approved. If the user is unable to fix the problem themselves, he or she has to visit the after-sales center or ask for a repair technician, because the process of finding and making a reservation is very cumbersome.

In order to learn, the sound data of the normal state and the sound data of each type of the abnormal state are converted into a spectrogram image using STFT (Short-Time Fourier Trasnform), and the converted spectrogram image is converted into a Convolutional Neural Network (CNN). ) can be used to extract feature data. After restructuring the vibration data of the steady state and the vibration data of each type of the abnormal state on the XYZ axis in the time domain, the feature data may be extracted using CNN. Here, when extracting feature data from the collected sound data and vibration data in a steady state, and sound data and vibration data for each type of abnormal state, the extracted feature data is analyzed based on LSTM (Long Short-Term Memory). can be re-extracted.

The task distribution unit 330 may allocate tasks for installation, transfer and maintenance of products to at least one operator terminal 400 . At this time, at least one driver's terminal 400 may be assigned a task for installation, transfer and maintenance of the product. Here, in one embodiment of the present invention, in the case of installation or transfer of a product, that is, when delivery and installation are to be performed together, tasks may be distributed so that the delivery driver and the installer move in pairs, not in pairs of two. there is.

In most cases of product installation or relocation, the product must be moved from the distribution center to the delivery location, or from the address before the relocation to the address after the relocation. At this time, in the case of most installations or relocation installations, a delivery driver and an installer are made up of a pair of two, and the delivery vehicle loads the assigned product at the warehouse and starts delivery after confirming the delivery plan. When the delivery vehicle arrives at the customer, the drivers carry the appliance, install it and explain the product. The delivery process in which delivery and installation services are integrated is difficult to cope with the uncertain volatility of logistics in real situations. If the time required to install home appliances and explain the product to users is not constant for each customer, it will have a major impact on the next delivery schedule.

For example, when installing home appliances, the installation space is narrow, so installation delays may occur, and product description times may be lengthened due to customer requests. Alternatively, there may be a waiting time because the customer does not answer the phone or open the door. If the installation and explanation time for home appliances is long, the next delivery destination will be delayed and the overall plan will be disrupted. And in order to move quickly to the next delayed delivery destination, the installation and explanation of home appliances is hastened, which reduces the quality of logistics service. The current delivery process causes unnecessary waiting time for delivery vehicles during home appliance installation and explanation times. Due to this waiting time, the amount of home appliances delivered by one delivery vehicle is reduced. And although the drivers of the delivery vehicle, which consist of a pair of two people, are responsible for delivery and service, the performance index does not consider service as important because only delivery, which is the number of deliveries, is important.

<Separation of shipping and installation>

So, in one embodiment of the present invention, in order to solve these problems, installation service technicians are arranged for each metropolitan area, delivery drivers are in charge of delivery of home appliances in groups of 1 person, and installation technicians are installed in groups of prime movers or small vehicles. You can distribute tasks to take care of services corresponding to the installation and description of home appliances while moving to This method can be more effective in the metropolitan area, which accounts for more than 70% of the total logistics volume. In a city with a small number of customers, the time interval between customers is wide, so it is possible to cope with uncertainty in service time.

In the case of allocating tasks according to an embodiment of the present invention, customers assigned to delivery drivers and installation drivers are different. When the delivery driver arrives at the delivery destination in a delivery vehicle, the home appliance is delivered to the customer just like the installer who arrived in advance. After that, the delivery driver moves to the next delivery destination, and the installer installs the appliance and explains the product to the customer. The delivery driver only needs to deliver the product at the customer's desired time, regardless of home appliance installation and training time. The unnecessary waiting time of delivery vehicles due to the installation and explanation of home appliances is reduced, so that one delivery vehicle can handle a large amount of volume. And since the installers don't have to think about the time for the next delivery destination, they can provide sufficient service to customers without being pressed for time. And even if the installation and explanation time of home appliances by the installer is delayed, the delivery plan is not affected. In this way, when delivery and installation services are dualized, it is possible to flexibly cope with the uncertainty of logistics. And, the performance index of delivery drivers is the number of deliveries, and the performance index of installers can be divided into installation or transfer, so each person takes responsibility.

<MACS-DSVRPTW for Shipping Scheduling>

In this case, for an embodiment of the present invention, synchronous delivery scheduling of a delivery driver and an installer for each customer is required. In this case, MACS-DSVRPTW (Multiple Ant Colonoy System-Delivery Service Vehicle Routing Problem with Time Window) may be used. At this time, MACS-VRPTW is an algorithm that solves VRPTW (Vehicle Routing Problem with Time Window) while independently moving two ant colonies with different purposes. Here, among the types of Vehicle Routing Problem (VRP), VRPTW (VRP with Time Window) is a vehicle routing problem with a time constraint requested by customers. Since VRPTW is an NP-Hard problem, it cannot find an optimal solution within a limited time. So, in order to solve this problem, a heuristic method is used to generate several solutions through local search and find a solution close to the optimal solution within it, which includes the Heuristic Algorithm and the Metaheuristic Algorithm.

In one embodiment of the present invention, since it is necessary to solve the problem of the path of the installer, such as a vehicle, the MACS-DSVRPTW which adds two ant colonies that minimizes the number and movement path of the installation service technician to the existing MACS-VRPTW Using MACS-DSVRPTW do it with The ant colony system is a metaheuristic method that mimics the behavior of real ants. Actual ants secrete a chemical called pheromone on the path while searching for food, and the ants determine the next path by looking at the secreted pheromone trail. In the process of the ACS algorithm, the number of agents as many as the set number of ants selects the first node to go to, and then selects the next node to visit according to the State Transition Tole. In the process of selecting each node, ant agents change the amount of pheromone in the link between visited nodes according to the Local Updating Rule. And after the search process of the ant agent is finished, the best solution is to change the amount of pheromone according to the Global Updating Rule.

Here, MACS-DSVRPTW is an algorithm that achieves the overall goal in a basic ACS algorithm while four ant colonies with different goals move independently. Among the two ant colonies with MACS-DVRPTW (Multiple Ant Colony System for Delivery Vehicle Routing Problem with Time Window), the main purpose of solving the routing problem of delivery vehicles, ACS-DVEI aims to minimize the number of delivery vehicles, -DTIME has the purpose of minimizing the route time of the delivery vehicle. And among the two ant colonies with MACS-SVRPTW (Multiple Ant Colony System for Service Vehicle Routing Problem with Time Window), which is the main purpose of solving the problem of the path problem of installers, ACS-SVEI has the purpose of minimizing the number of installers, ACS-STIME aims to minimize the path time of the installer.

First, pheromone information is initialized in the initialization process of the ACS algorithm, and the first node is selected for each ant agent according to the initialization rule. The number of ant agents belonging to the ant colonies of MACS-DVRPTW is the same as the number of vehicles, and the first node to go to is arranged in the order of the customer with the fastest time to receive delivery. The number of ant agents belonging to the ant colonies of MACS-SVRPTW is the same as the number of installers, and the first node to go to is placed in the order of the customer who wants to receive the installation service the fastest. Initially, each ant agent becomes a warehouse (service center)-first customer node-warehouse (service center) path. Select the node to enter between the customer node and the warehouse (service center) according to the state transition rule. First, each ant agent checks whether it is a node that can enter between unvisited customer nodes. The ant colonies of delivery drivers find nodes that meet the constraints of load capacity, customer demand time, and operating time. The ant colonies of the installers search for possible nodes within the constraints of customer requirements and business hours. And the optimal solution search process is carried out to find the next solution by checking whether it arrives earlier than the delivery driver or whether they can come at the same time, finds the initial solution, and then changes the amount of pheromone in the ant colony algorithm.

The transmitter 340 may transmit a schedule of at least one driver's terminal 400 to the user terminal 100 . The transmission unit 340 may transmit a result of scheduling optimization using an optimal solution or the like to the driver terminal 400 and the user terminal 100 .

The talent training unit 350 may provide educational content that an engineer of the at least one article terminal 400 needs to learn in order to provide a care service, and check whether the article has been completed and manage it.

The intermediary unit 360 may receive a selection of any one of direct transaction, consignment transaction, and purchase transaction of a product from the user terminal 100 for used transaction of the product and mediate the user terminal 100 and the counterparty to the transaction. A direct transaction is a transaction in which the intermediary unit 360 provides a secure transaction, removal or transfer service for used transactions between individuals, and the platform itself does not participate in the transaction. Consignment transaction is a transaction where the seller must move immediately but the buyer does not appear. In this case, the transaction proceeds by asking the platform to sell instead, and in the purchase transaction, the platform purchases the product from the seller and then finds a buyer in the seller's position and sells it.

The profile providing unit 370 may upload and disclose the type and number of care services allocated and completed to the at least one article terminal 400 , related certification information, and review and rating information.

The consulting unit 380, when purchasing and installing from the user terminal 100, receives a picture and a video of the place to be installed from the user terminal 100, and includes information on the type and capacity of the product desired or possessed. address can be received. At this time, if the product is an air conditioner, the consulting unit 380 instructs to shoot a video along the movement line from the place where the air conditioner is to be installed and the place where the outdoor unit is to be installed, and can extract the object and distance within the video. . And, when the product is an air conditioner, the consulting unit 380 receives a selection of a basic unit price for each type and capacity of the air conditioner from the user terminal 100, and selects an additional option including whether or not additional pipe length and angle are required, and installation cost can be calculated.

The ventilation unit 390, when the user terminal 100 is linked with at least one window or door based on IoT (Interent of Things), when the product registered in the user terminal 100 is driven, at least one window or door A control signal may be transmitted to open and close the device at a preset cycle. For example, if the product is an air conditioner, ventilation is not often provided to prevent cold air from escaping to the outside, but in the case of restaurants or cafes, since an unspecified number of people use and come and go, ventilation is necessary to lower the density of the corona virus and lower the risk of infection. If you instruct employees to ventilate every 10 minutes, this can also act as a workload during busy times, so you can automatically open and close or control the fan to start when connected via IoT.

In addition, in one embodiment of the present invention, after allocating the task to each engineer in the country, the type of task assigned, the address or residence type of the user who requested the care service, the date, day and time, in the case of transfer or installation, transfer or By collecting and accumulating data such as volume such as weight and volume of products to be installed, artificial intelligence algorithms can be modeled for the purpose of predicting the time required to provide each service. For example, in the case of a previous installation, it is necessary to remove it from the current location, load it in a vehicle, and deliver it back to the delivery address. At this time, the variables of demolition on the 50th floor of an apartment and detaching on the first floor of a house are different. . In the former case, even if there is an elevator, it may take a long time to move due to the number of floors. In the latter case, it does not take long to get down to the ground, but if it is located in a narrow alley where delivery vehicles cannot enter, more manpower is required to move it. Since the circumstances of each delivery address or the address where the care service is applied are different, if you set all these variables and train when sufficient data is accumulated, you can estimate the expected time when scheduling and can be used for task distribution and scheduling. can

For prediction, for example, machine learning models can use Decision Tree, Random Forest, Gradient Boosting, Support Vector Classification, Multi Layer Perception, etc. is available. The decision tree model is a tree model by dropping branches with Yes or No. Typically, there are pre-pruning methods for parameters that are changed for model performance, and it is a model composed of nodes and leaves. A random forest can be said to be an ensemble model that mixes various tree models, and a representative parameter can be said to be the number of independent variables to be considered in the model. Gradient boosting is a method of creating a model by clustering several trees in a similar way to a random forest. The difference from a random forest is to create a model in a way that compensates for the error of the tree. You can change the performance in various ways. The support vector machine model is a model that creates support vectors that become the boundaries of the values of the dependent variable. Also called SVM (Support Vector Machine), the classification decision is based on the distance of the support vectors, but the accuracy of the vector is learned through the training process. The multilayer perceptron model is also commonly referred to as a neural network algorithm, and important parameters are the number of units in the hidden layer and the number of hidden layers.
