Description

Technical Field

[0001] The present invention relates to the technical field of flower management, and in particular to a flower sales management system and method based on blockchain technology. Background Art

[0002] With the rapid development of the economy, people's demand for flowers is increasing. Most of the flower transactions are still traditional offline transactions. With the rapid development of e-commerce, online transactions are becoming more and more common, and online shopping of flowers is also gradually developing.

[0003] In the existing flower trading process, flower trading is subject to huge restrictions such as time, space, weather, and information, and is traditional and backward. The environment for flower planting, storage, and logistics transportation has extremely stringent requirements. Flower planting is easily affected by environmental factors, and the yield and quality are unstable. The flower trading chain is too long, and the transportation environment conditions vary greatly, resulting in excessive flower consumption. When flowers are delivered to consumers, the flowers are not fresh enough, which causes interest disputes with merchants and logistics companies, making it difficult to determine the responsibility for the flower problems.

[0004] The flower market is chaotic, with problems such as selling inferior products as good ones, product substitution and adulteration, and information asymmetry. There is no quality inspection of flowers in each link of flower planting and transportation, and the quality control of flowers is insufficient, resulting in reduced consumer satisfaction and hindering the development of online flower transactions. The online flower display examples are single, and consumers have no desire to buy, resulting in low sales. The development of flower companies is inhibited, and it is difficult to create high-quality flower brands. Summary of the invention

[0005] The purpose of the present invention is to collect data from the flower planting and logistics transportation links and store them on the blockchain to ensure the authenticity of the data. The sensor is combined with automatic control equipment to automatically adjust the abnormal environment, which solves the problem of excessive flower loss in the flower transportation link. Quality inspection is carried out in the picking, transportation and receipt of flowers to solve the problem of insufficient control of flower quality and reduced consumer satisfaction. The data of each node is uploaded to the blockchain storage module in real time to ensure that the data cannot be tampered with. Each abnormal record is bound to the flower identification to form a complete traceability chain, quickly locate the party responsible for the problem, and solve the problem that the background technology is difficult to determine the party responsible for the flower problem.

[0006] The technical solution adopted by the present invention is as follows: The present invention is a flower sales management system based on blockchain technology, including a data acquisition module, a blockchain storage module, a user access module, a smart contract module, a test module, and an abnormal monitoring and feedback module. Specifically: The data collection module is used to collect data on the flower planting and logistics transportation stages. The data is transmitted to the blockchain storage module in real time and bound to the flower identification; The blockchain storage module is based on blockchain technology and is used to store flower information, storing data on the entire life cycle of flowers in a distributed ledger; User access module: consumers view flower display legends and flower-related information on the user end. Consumers select bouquets according to their needs. The user end matches the required flower types, or generates a bouquet image after consumers select the flower types, and configures the bouquet production steps in detail under the bouquet image to assist consumers in buying flowers. After consumers place an order for flowers, they view the order information and data information on the entire life cycle of the flowers through the user end; Smart contract module, used to generate order information, perform payment settlement and automated account splitting, and verify the authenticity and validity of data in each link; The inspection module is used to inspect the quality and information of flowers. During the logistics and transportation stages and the consumer’s receipt stages, the logo on the flowers is scanned to obtain the full process information of the flower planting and logistics transportation stages. The quality is certified based on the data in the blockchain storage module. When the quality of the flowers does not meet the standards, feedback is provided and recorded in the order information. The abnormality monitoring and feedback module records and sends notifications in a timely manner when abnormalities are found during the planting, transportation or sales process. Through the tamper-proof data of the blockchain storage module, the smart contract module automatically traces the data on the chain, quickly locates the problem node, and provides solutions.

[0007] Furthermore, the data collection module collects data from the flower planting process, including the planting site information of flower farmers, flower variety information and environmental data during the flower planting process, and uploads the data to the blockchain storage module; a first identifier is marked on flowers of the same variety in the same planting site or the same greenhouse, and the planting site information of the flower farmers and the flower variety information are identified by the first identifier for information entry; the environmental data during the flower planting process is collected by deploying Internet of Things devices, such as temperature and humidity, light intensity, soil moisture and oxygen concentration, and the collected environmental data is encrypted and stored in the blockchain storage module and bound to the first identifier.

[0008] Furthermore, the data collection module collects data on the logistics and transportation of flowers and records the whole process information of flower picking and transportation; After the consumer places an order, the order information and the second identifier are generated. After receiving the order, the merchant selects flowers for picking, packaging and delivery according to the order information. When packaging, the second identifier is affixed to the flowers and packaging boxes. The second identifier is synchronously associated with the flower information bound to the first identifier; When transporting flowers, GPS positioning devices and IoT devices are installed in the transport vehicles. The GPS positioning devices upload the flower transportation location information in real time. The IoT devices collect environmental data during the flower transportation process, including temperature, humidity, vibration and gas concentration, to ensure that the transportation environment conditions are suitable. Combined with blockchain technology, the location information and environmental data of flowers during transportation are synchronously uploaded to the blockchain storage module and bound to a second identifier to achieve visual tracking throughout the entire process.

[0009] Furthermore, the IoT device is a multifunctional or multi-type sensor. A set of IoT devices is deployed in the same planting site, the same greenhouse or the same transport vehicle to collect environmental data of the flower planting link or the flower logistics transportation link. The sensor is waterproof, dustproof and shockproof to adapt to different planting environments. In addition, the sensor is equipped with a solar power supply system to extend the battery life of the sensor to adapt to long-term unattended planting sites or long-distance transportation.

[0010] Furthermore, the sensor is an embedded sensor with edge computing capabilities. Automatic control equipment is deployed in each flower farmer's planting site and transportation vehicle, and the automatic control equipment is connected to the embedded sensor network. Before the environmental data collected by the sensor is uploaded to the blockchain storage module, the data is pre-processed by an embedded algorithm, and only important data is uploaded to reduce network transmission pressure. At the same time, environmental data analysis is performed to detect abnormal environmental parameters and determine whether an alarm is needed or the automatic control equipment is controlled to adjust environmental conditions.

[0011] Furthermore, the first identification of the flower planting link and the second identification of the flower logistics transportation link are both QR codes or RFID tags. The data transmission of the data acquisition module adopts TLS protocol encrypted data transmission to prevent data tampering and leakage during transmission. According to the distributed ledger characteristics of blockchain, the data is recorded on the chain to ensure that the data cannot be tampered with. Each data is timestamped and hashed, and data verification is achieved through the smart contract module to ensure data authenticity.

[0012] Furthermore, the inspection module includes a first inspection when the flowers are packaged, a second inspection before signing for them, and a third inspection when the consumer signs for the flowers. When flowers are picked and packaged, they need to be inspected and confirmed for the first time, and the information is recorded in the blockchain storage module. Before the flowers arrive at the consumer for signature, the logistics company needs to conduct a second inspection and confirmation, and record the information in the blockchain storage module. The information of the first and second inspections is compared, and the system determines the comparison deviation, determines whether the flowers are qualified, and records it; When signing for the flowers, consumers will conduct a third inspection of the appearance and information of the flowers and upload the verification information to the order information.

[0013] A flower selling management method based on blockchain technology, applicable to the above-mentioned flower selling management system, comprises the following steps: When flowers are planted, IoT devices are deployed at the planting site to collect data on each batch of flowers. These data are uploaded to the blockchain storage module in real time and bound to the first identifier of the batch of flowers. When the merchant sells flowers on the merchant side, he scans the first identifier of the flowers, enters the display legend and corresponding value of the flowers according to the classification of different varieties of flowers, distinguishes and enters the transportation conditions for each type of flowers, and stores the entered data in the blockchain storage module; Consumers obtain flower display legends and flower-related information through the user end, and make purchases and place orders according to their needs. After the consumer places an order, the system will generate order information and a second identifier based on the smart contract module, and store them in the blockchain storage module, and complete payment and account splitting according to the rules agreed in the contract; After receiving the order, the merchant selects flowers for picking, packaging and delivery according to the order information. When packaging, a second mark is affixed to the flowers and packaging boxes, and the second mark is synchronously associated with the flower information bound to the first mark. When shipping, the shipping information is entered and stored through the blockchain storage module; During the transportation of flowers, the environmental data of logistics and transportation is obtained in real time through the Internet of Things devices, and the transportation route is tracked through the GPS positioning device to obtain the transportation location information of the flowers. The environmental data and location information will also be uploaded to the blockchain storage module and bound to the second identification of the flowers. The logistics data is updated to the order information. Consumers and merchants can view the complete transaction history and understand the source and logistics of the flowers. After the logistics delivery is completed, the consumer enters the receipt information into the order information when signing for the flowers; When flowers have quality problems during planting, transportation or sales, scan the first or second identification code and promptly provide feedback to the system. Through the system's tamper-proof data, the party responsible for the problem can be quickly located and a solution can be provided.

[0014] Furthermore, the consumer is an individual or a flower shop. When the consumer is a flower shop, the second mark on the flower package can be scanned by the mobile terminal to record the sales information of the flowers, so as to help the flower shop to manage accounts or count inventory and avoid inventory backlogs or supply shortages. When individuals purchase through offline flower shops, they can also scan the second mark to obtain flower information and timestamps, so that the quality of the purchased flowers can be guaranteed.

[0015] In summary, due to the adoption of this technical solution, the beneficial effects of the present invention are: 1. The present invention is a flower sales management system based on blockchain technology.

[0025] All features disclosed in this specification, or steps in all methods or processes disclosed, except mutually exclusive features and / or steps, can be combined in any manner.

[0026] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0027] The specific implementation example is as follows:

[0028] Embodiment 1 like Figure 1As shown, the present invention is a flower sales management system based on blockchain technology, including a data acquisition module, a blockchain storage module, a user access module, a smart contract module, a test module and an abnormal monitoring and feedback module, specifically: The data collection module is used to collect data on the flower planting and logistics transportation stages. The data is transmitted to the blockchain storage module in real time and bound to the flower identification; The blockchain storage module is based on blockchain technology and is used to store flower information, storing data on the entire life cycle of flowers in a distributed ledger; Preferably, the data acquisition module collects data from the flower planting process, including the planting site information of flower farmers, flower variety information and environmental data during the flower planting process, and uploads the data to the blockchain storage module; a first identifier is marked on flowers of the same variety in the same planting site or the same greenhouse, and the planting site information of the flower farmers and the flower variety information are identified by the first identifier for information entry; the environmental data during the flower planting process is collected by deploying Internet of Things devices, such as temperature and humidity, light intensity, soil moisture and oxygen concentration, and the collected environmental data is encrypted and stored in the blockchain storage module and bound to the first identifier.

[0029] The data collection module collects data on the logistics and transportation of flowers and records the whole process information of flower picking and transportation; After the consumer places an order, the order information and the second identifier are generated. After receiving the order, the merchant selects flowers for picking, packaging and delivery according to the order information. When packaging, the second identifier is affixed to the flowers and packaging boxes. The second identifier is synchronously associated with the flower information bound to the first identifier; When transporting flowers, GPS positioning devices and IoT devices are installed in the transport vehicles. The GPS positioning devices upload the flower transportation location information in real time. The IoT devices collect environmental data during the flower transportation process, including temperature, humidity, vibration and gas concentration, to ensure that the transportation environment conditions are suitable. Combined with blockchain technology, the location information and environmental data of flowers during transportation are synchronously uploaded to the blockchain storage module and bound to a second identifier to achieve visual tracking throughout the entire process.

[0030] In the present invention, there are hundreds or thousands of flowers of the same variety in the same planting site or the same greenhouse, and the growth cycle of flowers is long. If different identifiers are bound to each flower, the identifier will be contaminated during the growth of the flower, which is not conducive to the logistics transportation and sales of the flowers in the later stage. In addition, it is time-consuming and labor-intensive to bind an identifier to each flower in the planting site, and the labor cost is high. The present invention uses a first identifier to mark the same variety of flowers in the same planting site or the same greenhouse. It only needs to set a first identifier in the greenhouse or the planting site. For flowers of different varieties, different first identifiers are set. In the same planting site or the same greenhouse, a set of Internet of Things devices is deployed. Environmental data collected by the Internet of Things devices is uploaded to the blockchain storage module. According to different flower varieties or different planting sites, different first identifiers can be associated. The planting site information and flower variety information of the flower farmers can be entered into the system in advance. After the first identifier is set, it can be directly associated to avoid repeated entry of the same information.

[0031] After the flowers are picked, when they are packaged, a unique second identifier is obtained according to different orders, and a unique second identifier is affixed to the flowers and packaging boxes of each order. The environmental data information of the flower logistics and transportation link can be uploaded to the blockchain storage module and bound to the second identifier. The second identifier is synchronously associated with the data information of the first identifier. The second identifier includes all the data information of the first identifier of the flower. The second identifier can also be customized according to the flower variety or merchant brand.

[0032] The first identification of the flower planting link and the second identification of the flower logistics transportation link are both QR codes or RFID tags. The data transmission of the data acquisition module adopts TLS protocol encrypted data transmission to prevent data tampering and leakage during transmission. According to the distributed ledger characteristics of blockchain, the data is recorded on the chain to ensure that the data cannot be tampered with. Each data is timestamped and hashed, and data verification is implemented through the smart contract module to ensure data authenticity.

[0033] In this embodiment, the first identifier and the second identifier are displayed in the form of a QR code. The distributed ledger data of the blockchain storage module is stored on multiple nodes instead of being concentrated in a centralized server. The data of all nodes is synchronized. Once the data is written into the distributed ledger, it cannot be changed at will, which ensures the credibility of the data, and all consumers, logistics providers or merchants can view and verify it.

[0034] The Internet of Things device is a multifunctional or multi-type sensor used to collect temperature and humidity, light intensity, soil moisture and oxygen concentration, etc. Different sensors are installed according to different needs. A set of Internet of Things devices is deployed in the same planting site, the same greenhouse or the same transport vehicle to collect environmental data of the flower planting link or the flower logistics transportation link. The sensor is waterproof, dustproof and shockproof to adapt to different planting environments. In addition, the sensor is equipped with a solar power supply system to extend the sensor's battery life and adapt to long-term unattended planting sites or long-distance transportation.

[0035] The sensor is an embedded sensor with edge computing capabilities. Automatic control equipment is deployed in each flower farmer's planting site and transportation vehicle, and the automatic control equipment is connected to the embedded sensor network. Before the environmental data collected by the sensor is uploaded to the blockchain storage module, the data is pre-processed by an embedded algorithm, and only important data is uploaded to reduce network transmission pressure. At the same time, environmental data analysis is performed to detect abnormal environmental parameters and determine whether an alarm is needed or the automatic control equipment is controlled to adjust environmental conditions.

[0036] Embedded sensors are small hardware devices that integrate perception, processing, communication and control capabilities. Embedded sensors have built-in microprocessors or control units, and have lightweight edge computing capabilities. They can perform simple algorithms such as data normalization, outlier detection, statistical analysis, average calculation or trend analysis, etc. Embedded sensors filter, reduce noise and process outliers on the collected data to improve data quality, and transmit the pre-processed data to the blockchain storage module through a wired or wireless network to reduce network transmission pressure. Embedded sensors use edge computing to analyze and process data in real time, detect abnormal environmental parameters, and trigger automatic control equipment in flower planting areas or transportation vehicles, such as sprinkler systems and ventilation devices, to issue abnormal environmental alarms to remind staff to make adjustments.

[0037] For example, in the flower planting process, soil moisture sensors collect soil moisture data in real time, and the embedded algorithm automatically filters out outliers and calculates the daily average humidity to ensure a suitable environment for flower growth. In the flower logistics and transportation process, temperature and humidity sensors monitor the logistics and transportation environment in real time. If the temperature deviates from the set range, the embedded algorithm immediately triggers the ventilation device for ventilation, and alarms or sends notifications to alert staff to avoid deterioration in the quality of flowers.

[0038] The present invention adopts embedded sensors to realize intelligence of flowers in the data acquisition module, reduce the complexity of subsequent data processing, and improve the efficiency and reliability of the entire system.

[0039] User access module: consumers view flower legends and flower-related information on the user end. Consumers select bouquets according to their needs. The user end matches the required flower types, or generates a bouquet image after consumers select the flower types, and configures the bouquet production steps in detail under the bouquet image to assist consumers in buying flowers. After consumers place an order for flowers, they view the order information and data information on the entire life cycle of the flowers through the user end; Smart contract module, used to generate order information, perform payment settlement and automated account splitting, and verify the authenticity and validity of data in each link; In this embodiment, consumers can view the display legend of flowers and related information of flowers in the operation interface of the mobile phone APP or the web page, including the planting site information of flower farmers, flower variety information and environmental data during the flower planting process, as well as the expected logistics plan. Consumers choose flowers according to their needs or personal preferences. The system generates personalized flower bouquets or flower arrangements through preset bouquet templates or AI, displays the flower arrangement effect diagram in 3D, and configures detailed production steps on the details page, including flower material trimming, arrangement and packaging processes, etc. Among them, AI model training collects a large amount of bouquet image data, uses GAN or DALL.E model to train the bouquet image generation model, consumers select flowers and quantities, and the model outputs bouquet images. Consumers can also choose according to the use requirements and the display legend of flower art, for example, flowers required for weddings, holiday bouquets, conferences, exhibitions and other bouquet templates. The system directly matches the types and quantities of flowers required, and consumers choose to buy them by themselves. The above flower matching recommendations enhance consumers' desire to buy flowers, and users have seen the display effects of bouquets or flower arrangements before purchasing, reducing the return disputes caused by the actual objects not meeting expectations. In addition, since the display time of fresh flowers is short, in order to better preserve them, fresh flowers can also be made into dried flowers. The system is equipped with steps for making dried flowers.

[0040] After consumers place an order for flowers, the smart contract module is triggered, an order is automatically generated, and payment and account splitting are completed in accordance with the rules agreed in the contract to ensure transaction efficiency. Consumers can view the order information and the second identifier through the user terminal. The second identifier is bound to the entire process of flower planting, picking, logistics transportation to receipt.

[0041] The inspection module is used to inspect the quality and information of flowers. During the logistics and transportation stages and the consumer's receipt stage, the second mark on the flower packaging can be scanned to obtain the full process information of the flower planting and logistics transportation stages, and quality certification can be performed based on the data of the blockchain storage module. When the quality of the flowers does not meet the standards, feedback will be provided and recorded in the order information; The inspection module includes a first inspection when the flowers are packaged, a second inspection before signing for them, and a third inspection when the consumer signs for the flowers. Specifically, when flowers are picked and packaged, they need to be inspected and confirmed for the first time, and the information is recorded in the blockchain storage module. Before the flowers arrive at the consumer for signature, the logistics company needs to conduct a second inspection and confirmation, and record the information in the blockchain storage module. The data of the first inspection and the second inspection are compared, and the system calculates the comparison deviation to determine whether the flowers are qualified and records it. When consumers sign for the flowers, they conduct a third inspection and confirmation of the appearance and information of the flowers, and upload the verification information to the order information.

[0042] The quality of flowers determines the consumer satisfaction, and the consumer satisfaction directly affects the sales of flowers, so the present invention sets three inspections.

[0043] 1. First inspection, after picking the flowers: Inspection items, record the variety, quantity, appearance integrity, color brightness, petal status, humidity, temperature and other parameters of flowers; Data collection: taking pictures of flowers through image acquisition equipment and recording environmental parameters such as humidity and temperature through sensors; The data is uploaded, and the inspection results are encrypted and uploaded to the blockchain storage module, and associated with the second identifier of the flowers.

[0044] 2. Second inspection, before reaching the consumer: Inspection items, record the appearance, quantity, color change, damage, etc. of the flowers again; Data collection: also record relevant data through image acquisition devices and sensors; Data upload: The inspection results are encrypted and uploaded to the blockchain storage module, and associated with the second identifier of the flowers.

[0045] 3. Carry out quality certification, compare deviations, and determine whether the flowers are qualified: The system automatically compares the data of the first and second inspections, including image similarity analysis, environmental parameter deviation calculation, etc. According to the set tolerance threshold, it determines whether the flowers meet the standards, for example: the image similarity is greater than the set threshold of 90%, and the changes in environmental parameters such as temperature and humidity are less than the allowable range, such as humidity change <10%, temperature change <5℃.

[0046] Deviation calculation of environmental parameters such as temperature and humidity. For example, the temperature deviation is equal to the absolute value of the second test temperature value minus the first test parameter value. If the deviation is greater than the preset threshold of 5°C, it is marked as unqualified.

[0047] Use computer vision techniques to compare the flower images taken during the two inspections: Based on feature matching, use ORB / SIFT algorithm to extract features and calculate the proportion of matching features; Based on deep learning, use a pre-trained model to extract image feature vectors, such as the ResNet model, and then calculate the cosine similarity of the feature vectors:

[0048] in, and They are vectors and vector No. elements, is the vector dimension, is the cosine similarity. The value of cosine similarity is between [-1, 1]. The closer the value is to 1, the more similar the two vectors are. The closer the value is to -1, the less similar the two vectors are. When the value is 0, it means that the two vectors are orthogonal and completely unrelated. If the similarity is lower than the set threshold, it is marked as unqualified. The set value of the similarity threshold in this embodiment is 0.9.

[0049] According to the environmental parameter deviation and image similarity, a weighted scoring method can be used to generate a comprehensive score for statistical analysis.

[0050] If the system determines that the flowers are unqualified, the system will push an alarm and submit them for manual review.

[0051] 4. The third inspection, when the consumer signs for the goods: When signing for the flowers, consumers scan the second identification of the flowers through the mobile terminal to view the full life cycle data of the flowers, and compare it with the scan result of the second identification on the user-side APP to prevent malicious replacement of flower varieties and passing inferior products off as good ones; consumers upload flower pictures and evaluation information when signing for the flowers to the order record for after-sales feedback; consumers' verification information will be synchronized to the blockchain storage module to form a complete data closed loop. The third inspection when the consumer signs for the flowers is also compared with the data of the first and second inspections, and the tolerance threshold is set to determine whether the flowers meet the standards.

[0052] Through the inspection module of the present invention, consumers can clearly understand the entire process information of flowers from picking to signing, and timely discover abnormal problems in the logistics and transportation process through deviation and image similarity analysis, reduce losses, and improve the pass rate. In addition, the flower information on the user side is compared with the flower information signed for to prevent malicious replacement of flower varieties and passing inferior products off as good ones. The consumer's signing verification makes consumers feel high-quality service, and at the same time provides after-sales feedback channels, provides consumers with compensation strategies, and enhances consumer service satisfaction.

[0053] The abnormality monitoring and feedback module records and sends notifications in a timely manner when abnormalities are found during the planting, transportation or sales process. Through the tamper-proof data of the blockchain storage module, the smart contract module automatically traces the data on the chain, quickly locates the problem node, and provides solutions.

[0054] In the present invention, the data of the planting, transportation or sales process of flowers are all stored on the blockchain storage module to ensure that the data cannot be tampered with. Each abnormal record is bound to the flower's identification to form a complete traceability chain. For example, flowers wither due to abnormal temperature during transportation. Through blockchain tracking, it is found that the flowers have temperature deviations in the logistics stage, and the responsibility belongs to the logistics party; for another example, consumers report quality problems of flowers. After comparison, it is found that the flowers have defects in the planting stage, and the responsibility belongs to the planting party.

[0055] Embodiment 2 like Figure 2 As shown, the present invention is a flower selling management method based on blockchain technology, which is applicable to the flower selling management system based on blockchain technology. The specific steps are: S1, when flowers are planted, collect data on the planting process of flowers and bind the first identification. Specifically: when flowers are planted, collect data on the planting process of each batch of flowers through the IoT devices deployed at the planting site, upload these data to the blockchain storage module in real time, and bind the first identification of the batch of flowers.

[0056] S2, the merchant sells flowers on the merchant side. Specifically: the merchant scans the first identifier of the flowers, enters the display legend and corresponding value of the flowers according to the classification of different varieties of flowers, distinguishes and enters the transportation conditions of each type of flowers, and stores the entered data in the blockchain storage module.

[0057] S3, consumers purchase flowers through the user end. Specifically: consumers obtain flower display legends and flower-related information through the user end, and make purchases and place orders according to their needs. After the consumer places an order, the system will generate order information and a second identifier based on the smart contract module, and store them in the blockchain storage module, and complete payment and account splitting according to the rules agreed in the contract; Specifically, the consumer is an individual or a flower shop. When the consumer is a flower shop, the second mark on the flower package can be scanned by the mobile terminal to record the sales information of the flowers, so as to help the flower shop to manage accounts or count inventory and avoid inventory backlogs or supply shortages. When individuals purchase through offline flower shops, they can also scan the second mark to obtain flower information and timestamps, so that the quality of the purchased flowers can be guaranteed.
