Technical Field

[0001] This invention belongs to the field of blockchain technology, specifically relating to a data acquisition method, device, and electronic device. Background Technology

[0002] With technological advancements and societal progress, more and more people are installing laundry and garment care equipment in their homes. While users can use these devices to wash and care for their clothes, sometimes they opt for professional laundry services for better cleaning and care.

[0003] Currently, in order to better understand the washing and care of their clothes, users need to obtain data related to clothing washing and care. This means that users obtain their washing and care data at home from their home washing and care devices, and they also obtain their consumption data at the laundry store.

After receiving a clothing data acquisition request sent by a target user's terminal, the method directly acquires the target clothing data required by the target user from the blockchain. Specifically, it can directly acquire first laundry care data and clothing laundry care consumption data from the blockchain. The first laundry care data represents the target user's laundry care data in a first area (e.g., at home), and the clothing laundry care consumption data represents the target user's consumption data in a second area (e.g., a laundry shop). The first laundry care data and clothing laundry care consumption data are then sent to the target user, enabling the target user to quickly obtain clothing laundry care-related data without needing to go to a laundry shop to retrieve their clothing laundry care consumption data or retrieve their home laundry care data from their home laundry equipment. This improves data acquisition efficiency. Furthermore, the first laundry care data is acquired from laundry equipment in the first area and directly stored on the blockchain, while the clothing laundry care consumption data is acquired from terminal devices in the second area and directly stored on the blockchain, achieving data source chaining and ensuring data authenticity and reliability.

[0055] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0056] The terms “first,” “second,” “third,” “fourth,” etc. (if present) in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that embodiments of the invention described herein can be implemented, for example, in orders other than those illustrated or described herein. Furthermore, the terms “comprising” and “having,” and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0057] Existing laundry scenarios, including home and store scenarios, store data differs depending on where the user washes clothes at home versus at a laundry store. When a user washes clothes at a laundry store, the corresponding consumption data is stored there. When a user needs to retrieve data related to a specific laundry scenario, they must first obtain the relevant washing and care data from their home laundry equipment, and then go to the laundry store to obtain the corresponding consumption data. However, because retrieving consumption data from the laundry store requires manual processing, and retrieving data from home laundry equipment requires processing at home, the data retrieval process is cumbersome, inefficient, and results in a poor user experience.

[0058] Therefore, to address the aforementioned problems, the technical concept of this invention is that after the laundry and care equipment in the first area (i.e., the home) acquires the laundry and care data, it encrypts and saves the data to the blockchain via IoT Chain No. 1. Similarly, after the read / write equipment in the second area (i.e., the laundry store) acquires the laundry and care consumption data, it encrypts and saves it to the blockchain. Upon receiving a user's request to retrieve clothing data, the system retrieves the corresponding laundry and care data and clothing consumption data from the blockchain and sends them to the user. This allows the user to quickly obtain data related to the laundry scenario, achieving rapid data acquisition and thus improving data acquisition efficiency.

[0059] The preferred technical solutions of the data acquisition method, apparatus, and electronic device of the present invention are described below with reference to the above-mentioned accompanying drawings.

[0060] Figure 1 This is a schematic diagram of a scenario for the data acquisition method provided in an embodiment of the present invention, such as... Figure 1 As shown, when a user needs to obtain data related to the laundry scenario, the user terminal 101 sends a clothing data acquisition request to the electronic device 102, so that the electronic device 102 can obtain the data related to the laundry scenario, i.e., the target clothing data, from the blockchain and send the target clothing data to the user terminal 101.

[0061] The user terminal 101 can be a mobile terminal (e.g., a smartphone, PDA, tablet computer, or other mobile device with camera capabilities, or a wearable electronic device), or a computer device (e.g., a desktop computer, laptop computer, all-in-one computer, or smart home device).

[0062] Among them, electronic device 102 can be a server, computer equipment, etc., specifically a device for building a blockchain platform.

[0063] Figure 2 Flowchart of the data acquisition method provided in the embodiments of the present invention Figure 1The execution entity in this embodiment can be Figure 1 The electronic devices shown in the illustrated embodiments are not specifically limited in this embodiment. Figure 2 As shown, the method includes:

[0064] S201. Obtain the clothing data acquisition request sent by the target user terminal corresponding to the target user.

[0065] In this embodiment, when a target user needs to obtain clothing data related to home laundry scenarios and consumption data related to store laundry scenarios, the target user inputs relevant operations on the target user terminal to generate a clothing data acquisition request and sends the clothing data acquisition request to the electronic device so that the electronic device can use the clothing data acquisition request to obtain the clothing data required by the target user.

[0066] S202. Obtain target clothing data from the blockchain according to the clothing data acquisition request. The target clothing data includes first washing and care data and clothing washing and care consumption data. The first washing and care data is collected by the washing and care device corresponding to the target user in the first area and saved to the blockchain. The clothing washing and care consumption data is obtained by the terminal device in the second area and saved to the blockchain.

[0067] In this embodiment, when the electronic device receives a clothing data acquisition request sent by the target user terminal corresponding to the target user, it indicates that the user needs to acquire clothing data related to the laundry scenario. Then, the target clothing data corresponding to the clothing data acquisition request is retrieved from the blockchain that stores clothing data of multiple users, that is, the target clothing data corresponding to the target user is acquired.

[0068] The target laundry data includes primary laundry care data related to home laundry scenarios for the target user, as well as clothing care consumption data related to in-store laundry scenarios for the target user. Primary laundry care data is collected by laundry care devices corresponding to the target user within a first area and stored on the blockchain. Specifically, when the target user uses laundry care devices within the first area (i.e., at home) to wash clothes, the devices collect the corresponding laundry care data, which is then used as primary laundry care data and stored on the blockchain to achieve on-chain processing of the primary laundry care data.

[0069] Correspondingly, the clothing washing and care consumption data is obtained by the terminal devices in the second area and stored in the blockchain. That is, when the target user washes clothes using the washing and care equipment in the second area (i.e., the laundry store), the terminal device obtains the consumption data corresponding to the target user and saves it in the blockchain.

[0070] The first laundry and care device corresponding to the target user refers to the laundry and care device bound to the target user. The first laundry and care device includes washing machines, smart wardrobes, dryers, and other devices that process clothes. The first laundry and care data includes data related to washing clothes, such as soaking data (e.g., soaking time, water usage), washing data (e.g., washing mode, time, water usage), rinsing data (e.g., rinsing time, water usage), and spin-drying data (e.g., spin-drying time, spin speed). The first laundry and care data also includes data related to clothing care, such as care mode and care time.

[0071] The terminal devices include user information reading and writing devices, which are used to read user information and, after reading the user information, save the user information and the reading time (i.e., consumption time) to the blockchain. Correspondingly, clothing washing and care consumption data includes user information and its corresponding consumption time.

[0072] Furthermore, optional user information reading and writing devices include radio frequency identification (RFID) readers, channel readers, etc.

[0073] Alternatively, user information may include user identifiers (e.g., user ID, user mobile phone number, ID card number, name, etc.) or other user-related information, such as the user's work address.

[0074] Optionally, the terminal device may also include a laundry and care device used to collect laundry and care data. Correspondingly, the laundry and care consumption data also includes secondary laundry and care data. When a user washes clothes in a secondary area (i.e., a laundry store), the laundry and care device in the secondary area washes the clothes, and the laundry and care device acquires the laundry and care data, uses it as secondary laundry and care data, and then saves the secondary laundry and care data to the blockchain to realize the on-chain storage of laundry and care consumption data.

[0075] The second set of laundry care data includes data related to washing clothes, such as soaking data (e.g., soaking time, water usage), washing data (e.g., washing mode, time, water usage), rinsing data (e.g., rinsing time, water usage), and spin-drying data (e.g., spin-drying time, spin speed). The first set of laundry care data also includes data related to caring for clothes, such as care mode and care time.

[0076] For ease of description, the washing and care equipment in the first area is referred to as the first washing and care equipment, and the washing and care equipment in the second area is referred to as the second washing and care equipment.

[0077] Additionally, optional data on clothing washing and care consumption may include the frequency of consumption by target users in the second region, i.e., the frequency of consumption at laundry stores, such as how often they wash and care for their clothes.

[0078] Alternatively, when saving clothing washing and care consumption data to the blockchain, the terminal device can do so directly by using its own installed IoT Blockchain No. 1 module. Correspondingly, when the first washing and care device saves the first washing data to the blockchain, it does so directly by using its own installed IoT Blockchain No. 1 module.

[0079] Furthermore, optionally, before saving the first washing and care data to the blockchain, the first washing and care device may first obtain a first key, use the first key to encrypt the first washing and care data, and then save the encrypted first washing and care data to the blockchain.

[0080] Accordingly, before saving clothing washing and care consumption data to the blockchain, the terminal device can first obtain the standard key corresponding to the target user, use the standard key to encrypt the clothing washing and care consumption data, and then save the encrypted clothing washing and care consumption data to the blockchain.

[0081] The first key can be a key corresponding to the first washing and care device, or a standard key corresponding to the target user of the first washing and care device. This standard key is generated based on the user information of the target user (e.g., user identifier). Furthermore, the first key can be a public key, a private key, or a symmetric key; there are no restrictions on this.

[0082] In this embodiment, in order to ensure the security of data storage, the clothing washing and care consumption data and the first washing and care data need to be encrypted before being saved to the blockchain. Then, the encrypted clothing washing and care consumption data and the first washing and care data are processed on the blockchain to ensure data security and prevent tampering.

[0083] In this embodiment, IoT Chain No. 1 integrates blockchain technology into hardware, possessing complete hardware expansion capabilities and functions such as digital identity authentication for IoT devices, privacy protection, data storage, and data traceability. It can efficiently empower various devices to achieve trusted data collection and privacy protection, thereby enabling terminal devices and the first washing and care device to directly save data to the blockchain.

[0084] In any embodiment, optionally, the target clothing data may further include first clothing label data and / or second clothing label data and second washing and care data.

[0085] Specifically, the first garment label data includes garment attribute information and / or standard washing instructions. When the target user washes the garment in the first area, the reading and writing device in the first area reads the label on the garment (e.g., hang tag, care label) to obtain the data on the label and uses it as the first label data.

[0086] The tags can be RFID tags, and the reading and writing devices in the first area can include RFID readers, first washing and care devices, etc., which can be devices that are tagged with clothing. Clothing attribute information includes information such as clothing material and standard washing and care methods. The standard washing and care methods indicate the optimal way to wash and care for clothing, which can guide users to properly wash and maintain their clothes.

[0087] Specifically, the second garment label data also includes garment attribute information and / or standard washing and care instructions. When a target user washes clothes in the second area, the reading and writing device in the second area reads the garment's label (e.g., hang tag, care label) to obtain the data on the label and uses it as the second label data.

[0088] Alternatively, the reading and writing devices in the second area may also include RFID reading devices, second washing and care devices, or other devices that can identify tags on clothing.

[0089] Furthermore, optionally, after reading the first clothing tag data, the reading and writing device in the first area can directly process it on the blockchain. That is, the first clothing tag data is read by the reading and writing device corresponding to the target user in the first area and saved to the blockchain. Correspondingly, after reading the second clothing tag data, the reading and writing device in the second area can also directly process it on the blockchain. That is, the second clothing tag data is read by the reading and writing device in the second area and saved to the blockchain.

[0090] Alternatively, after reading the first clothing tag data, the reading and writing device in the first area can send it to an electronic device so that the electronic device can process it on the blockchain. The specific process is as follows: obtain the first tag data sent by the reading and writing device in the first area; encrypt the first tag data; and save the encrypted first tag data to the blockchain.

[0091] Specifically, after the reading and writing device corresponding to the target user in the first area reads the tag data of the clothing, i.e. the first clothing tag data, it sends it to the electronic device. The electronic device encrypts the first clothing tag data and saves the encrypted first tag data to the blockchain so that when the target user needs to obtain the first tag data later, it can directly obtain it from the blockchain.

[0092] Alternatively, after reading the second clothing tag data, the reading / writing device in the second area can send it to an electronic device for on-chain processing. The specific process involves: obtaining the second tag data sent by the reading / writing device in the second area and obtaining the standard key corresponding to the target user; encrypting the second tag data using the standard key; and saving the encrypted second tag data to the blockchain.

[0093] Specifically, after receiving the second clothing tag data corresponding to the target user sent by the reading and writing device in the second area, the electronic device obtains the standard key corresponding to the target user. This standard key is generated based on the user information of the target user. Then, the electronic device uses the standard key to encrypt the second clothing tag data and uploads the encrypted second clothing tag data to the blockchain to ensure data security and prevent data from being tampered with.

[0094] It is understandable that when the reading / writing devices / laundry equipment in the first area and the second area save data to the blockchain, they will associate and save the data with user information so that users can retrieve relevant data based on their user information later. For example, when user A goes to the second area to wash clothes, the washing equipment in the second area will obtain the corresponding washing data while washing the clothes and save the washing data along with user A's user information to the blockchain.

[0095] S203. Send the first washing and care data and clothing washing and care consumption data to the target user terminal.

[0096] In this embodiment, after obtaining the first washing and care data and the clothing washing and care consumption data, that is, after obtaining the washing and care data of the target user when washing and caring for clothes at home and / or the consumption data of the target user in the laundry store, the electronic device sends the first washing and care data and the clothing washing and care consumption data to the target user terminal, that is, sends the data related to the laundry scenario to the target user terminal so that the target user corresponding to the target user terminal can obtain the data he / she needs.

[0097] Alternatively, when the target clothing data includes other data, that data may also be sent to the target user terminal; that is, all data included in the target clothing data must be sent to the target user terminal. For example, if the target clothing data also includes first clothing tag data and second clothing tag data, then the first clothing tag data and the second clothing tag data may also be sent to the target user terminal.

[0098] In addition, before sending the target clothing data to the target user terminal, that is, after obtaining the target clothing data from the blockchain, if the target clothing data is encrypted, it is necessary to decrypt the target clothing data, and then send the decrypted target clothing data to the target user terminal.

[0099] In this embodiment, the first laundry care device encrypts the acquired laundry care data during the laundry process and directly saves it to the blockchain, achieving data chaining from the data source and ensuring the authenticity and reliability of the first laundry care data in the blockchain. Similarly, after acquiring the laundry care consumption data, the terminal device in the second area encrypts the laundry care consumption data and directly saves it to the blockchain. This achieves data chaining from the data source and ensures the authenticity and reliability of the laundry care consumption data in the blockchain.

[0100] In this embodiment, the data obtained by users from relevant washing and care equipment and reading and writing devices in different laundry scenarios is encrypted and uploaded to the blockchain through IoT Chain No. 1, ensuring that the data is decentralized, secure, reliable and traceable.

[0101] As described above, after receiving a clothing data retrieval request from the target user's terminal, the system directly retrieves the target clothing data required by the target user from the blockchain. Specifically, it directly obtains the first laundry care data and clothing laundry consumption data from the blockchain. The first laundry care data represents the laundry care data generated by the target user using laundry equipment in the first area, i.e., data related to the home laundry scenario. The clothing laundry consumption data represents the consumption data generated by the target user when washing clothes in the second area, i.e., data related to the store laundry scenario. This first laundry care data and clothing laundry consumption data are then sent to the target user, allowing them to quickly obtain clothing laundry-related data without needing to visit a laundry store to retrieve their laundry consumption data or retrieve their home laundry data from their home laundry equipment. Furthermore, the first laundry care data is obtained from the laundry equipment in the first area and directly saved to the blockchain, while the clothing laundry consumption data is obtained from the terminal device in the second area and directly saved to the blockchain, achieving data source-to-chain verification and ensuring data authenticity and reliability.

[0102] Figure 3 Flowchart of the data acquisition method provided in the embodiments of the present invention Figure 2 In this embodiment Figure 2 Based on the previous embodiment, after receiving the clothing data retrieval request sent by the target user, it is necessary to verify the target user's identity to determine whether the target user is qualified to obtain the corresponding target clothing data. This process will be described in detail below with reference to a specific embodiment. Figure 3 As shown, the method includes:

[0103] S301. Obtain the clothing data acquisition request sent by the target user terminal corresponding to the target user.

[0104] S302. Obtain the user key sent by the target user terminal and obtain the standard key corresponding to the target user, wherein the standard key is a key generated based on the user information of the target user.

[0105] In this embodiment, the user key sent by the target user terminal is obtained, and the standard key corresponding to the target user is obtained. The standard key is a key generated based on the target user's specific tag, i.e., user information (e.g., user identifier), and is unique.

[0106] The user key can be sent separately by the target user terminal, or it can be added to the clothing data acquisition request when sending the clothing data acquisition request. In other words, the clothing data acquisition request carries the user key, and there are no restrictions on it here.

[0107] Alternatively, the clothing data acquisition request may also include the target user's user information, and correspondingly, the standard key corresponding to the target user can be obtained based on this user information.

[0108] S303. Determine whether the user key is the same as the standard key.

[0109] S304. If they are the same, then retrieve the target clothing data from the blockchain according to the clothing data retrieval request.

[0110] In this embodiment, the user key is compared with the standard key. If they are the same, it means that the user key sent by the target user terminal is the standard key corresponding to the target user. The target user's identity is successfully authenticated, and the target clothing data can be obtained from the blockchain according to the clothing data acquisition request.

[0111] Alternatively, when retrieving target clothing data from the blockchain, the standard key can be used to decrypt related data within the target clothing data (e.g., data acquired by a device in the second area) to achieve data decryption.

[0112] Alternatively, user keys can be used for authentication only when retrieving data from devices within the second region from the blockchain, such as clothing washing and care consumption data. Once authentication is successful, the data retrieved from the second region from the blockchain, i.e., clothing washing and care consumption data, can be obtained.

[0113] S305. Send the target clothing data to the target user terminal.

[0114] In this embodiment, after obtaining the target clothing data from the blockchain, the target clothing data is sent to the target user terminal so that the target user can quickly obtain the target clothing data, thus achieving rapid acquisition of the target clothing data.

[0115] S306. If they are different, stop retrieving the target clothing data from the blockchain based on the clothing data retrieval request.

[0116] In this embodiment, the user key is compared with the standard key. If the two are different, it indicates that the user key sent by the target user terminal is not the standard key corresponding to the target user. The identity authentication of the target user fails, and the target clothing data cannot be obtained from the blockchain. That is, the retrieval of the target clothing data from the blockchain according to the clothing data retrieval request is stopped to ensure data security and avoid data error transmission.

[0117] Alternatively, if it is determined that the user key is different from the standard key, a key error message can be sent to the target user terminal so that the target user can confirm whether the user key was sent incorrectly.

[0118] In any embodiment, optionally, after obtaining the target clothing data, the target clothing data can be analyzed to obtain the predicted washing and care information corresponding to the target user terminal, that is, to obtain the predicted washing and care information corresponding to the target user, and to control the washing and care equipment corresponding to the target user to perform washing based on the predicted washing and care information.

[0119] The predictive washing and care information includes predicted washing modes for different materials and / or other information related to washing clothes. The predictive washing and care information may also include predicted care modes for different materials and / or other information related to caring for clothes.

[0120] In this embodiment, after receiving a clothing data retrieval request from a target user, the target user's identity is authenticated based on the user key sent by the target user. Specifically, if the user key matches the target user's corresponding standard key, the target user's authentication is successful, and the required target clothing data can be retrieved from the blockchain according to the clothing data retrieval request. If the user key does not match the target user's corresponding standard key, the target user's authentication fails, and the required target clothing data is not retrieved from the blockchain. This ensures that only users with the key can query their own consumption data, i.e., the target clothing data, preventing information leakage, protecting user privacy, and guaranteeing the security of data retrieval.

[0121] Figure 4 This is a schematic diagram of the structure of the data acquisition device provided in an embodiment of the present invention, as shown below. Figure 4 As shown, the data acquisition device 40 may include a transceiver module 401 and a processing module 402.
