Description

Technical Field

[0001] This invention relates to the field of Internet of Things (IoT) technology, specifically to a data computing and retrieval method and apparatus for the IoT edge. Background Technology

[0002] IoT edge devices are intelligent devices located at the network edge of an IoT system, situated at the intersection of the physical and digital worlds. They directly connect to and manage physical entities and perform preliminary processing and analysis on the collected data. IoT edge devices are deployed close to the data source, which makes data collection more timely and accurate, reducing the possibility of data transmission delays and loss. IoT edge devices are used to collect various physical quantities or environmental parameters, such as temperature sensors, humidity sensors, light sensors, pressure sensors, and acceleration sensors. These sensors are widely used in environmental monitoring, industrial automation, smart homes, and other fields.

[0003] In the existing technology field, traditional data cleaning methods in IoT edge computing and retrieval often simply remove abnormal data or use fixed estimation methods for repair. When IoT edge devices are damaged and unable to upload data, they cannot accurately reflect the data that sensors should collect under normal working conditions, and can mislead data analysis results. Furthermore, IoT edge data computing and retrieval methods usually choose a fixed index type, which is difficult to adapt to the multimodal characteristics and complex query requirements of IoT data. They cannot dynamically adjust the index type according to the data access pattern, resulting in low retrieval efficiency in different query scenarios. Traditional parsing methods require users to input search requests in a fixed format, which is difficult to handle complex multi-condition related queries and cannot accurately understand and interpret the user's complex search intent. Summary of the Invention

[0004] The purpose of this invention is to provide a data computing and retrieval method and apparatus at the edge of the Internet of Things (IoT) to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a data computing and retrieval method for the edge of the Internet of Things, comprising the following steps:

[0006] Step 1: Data Preprocessing

[0007] 1. Data Acquisition and Formatting:

[0008] IoT edge devices collect raw data and aggregate the data to external data terminals;

[0009] Formatting data: The data terminal converts the data into a standard format and adds semantic tags to the numerical values ​​to indicate their acquisition environment;

[0010] 2. Data cleaning:

[0011] The data terminal identifies, removes, and corrects noisy data, and then stores it.

[0012] To handle missing values, if a certain IoT edge device fails to collect data at a certain time, it is marked as a missing value. The IoT edge device is then dispatched to diagnose the fault and repair it accordingly.

[0013] Step 2: Index Building:

[0014] 1. Selecting the index type: Based on the multimodal characteristics of IoT data, a hybrid indexing method is adopted. For IoT systems that simultaneously contain time-series environmental monitoring data and device geographic location information, the data terminal uses a hash index to quickly find specific devices, and a spatiotemporal index to handle queries related to geographic location and time.

[0015] 2. Index building: The data terminal builds an index for the data according to the selected index type;

[0016] Step 3: Execute the search:

[0017] 1. Parse the search request:

[0018] Natural Language Processing-Assisted Parsing: By introducing natural language processing technology, users can express their search requests in natural language, and the data terminal uses a lightweight natural language processing model to convert them into precise query conditions;

[0019] Multi-condition association parsing: By introducing text AI analysis technology, the data terminal identifies input errors in the search request and automatically corrects and estimates them. The data terminal uses AI algorithms to logically understand the long text input by the user, finds the logical relationships, and transforms them into corresponding query operations, thereby handling the complex association relationships between multiple search conditions.

[0020] 2. Use indexes for searching:

[0021] Parallel index lookup: When the data terminal uses a hybrid index or a distributed index based on the parsed key information, it performs parallel index lookup operations and finally summarizes the results.

[0022] Cache-based fast lookup: Establish a caching mechanism on the data terminal to cache the index results of frequently retrieved data, thereby improving the speed of the next lookup;

[0023] 3. Data extraction and return:

[0024] The data terminal retrieves data matching the search request from the storage location and presents the returned data in a personalized manner based on the user's device type and preferences.

The lifting module 616 can lift the electromagnetic chuck 617 to a specified height. The electromagnetic chuck 617 is installed at the bottom of the lifting end of the lifting module 616. The electromagnetic chuck 617 is electrically connected to the control module 52 and is controlled by the control module 52. The electromagnetic chuck 617 can magnetically connect with the electromagnetic connector 43.

[0060] The working principle is as follows:

[0061] Step 1: The staff drives the towing vehicle 1 to pull the trailer 2 to the designated location, and controls the control console 3 to start the lifting platform 7 and the mobile robot 41. The pre-programmed program inside the mobile robot 41 controls the mobile robot 41 to move along the surface of the lifting platform 7 to the outside of the trailer 2, and moves the mobile robot 41 to the corresponding position below the IoT edge device at the designated location. The pre-programmed program inside the mobile robot 41 controls the robotic arm 42, the angle adjustment platform 44 and the detection sensor 45 to start. The robotic arm 42 drives the angle adjustment platform 44 to move to the designated height position. The angle adjustment platform 44 drives the detection sensor 45 to move in multiple angle directions, so that the detection sensor 45 is aligned with the IoT edge device. The detection sensor 45 sends the image information and network signal data to the control console 3 through the mobile robot 41 for display, so that the staff can remotely determine the cause of the IoT edge device failure.

[0062] Step 2: When the mobile robot 41 needs to cross obstacles with narrow gaps, the operator controls the console 3 to activate the control module 52. The pre-programmed program inside the control module 52 activates the drive module 51, motion sensor 53, first motor 57, electric telescopic rod 67, miniature electric telescopic rod 613, electric roller 615, lifting module 616, electromagnetic chuck 617, and electromagnetic connector 43. Guided by the motion sensor 53, the drive module 51 moves to the left and right sides of the mobile robot 41. The two first motors 57 on the left and right sides drive the corresponding pulleys 56 to rotate. Under the tensioning and limiting action of the top pulley 56, the belt 5... The robot moves in an 8-directional direction, driving the left and right side belt clamps 64 to move the corresponding mounting brackets 61 outside the guide rail frame 54 to a designated height. The left and right side electric telescopic rods 67 extend and retract, driving the first mounting rod 68 to move the telescopic rod 69 to a position above the mobile robot 41 under the limiting action of the telescopic guide rail 66. The three side miniature electric telescopic rods 613 extend and retract, driving the corresponding second mounting rods 614. Under the limiting action of the three side limiting telescopic rods 612, the three side second mounting rods 614 drive the corresponding electric rollers 615 to move synchronously inward or outward, keeping the three side electric rollers 615 in contact with the telescopic rods 614. 9. The outer wall is fitted together. The internal motor of the electric roller 615 drives the roller to rotate, moving it to the left or right along the outside of the telescopic rod 69 with the cooperation of the sleeve frame 611 and the sleeve housing 610. This aligns the lower electromagnetic chuck 617 with the electromagnetic connector 43. The lifting module 616 drives the electromagnetic chuck 617 to descend to the designated height, magnetically engaging it with the electromagnetic connector 43. With the cooperation of the electromagnetic chuck 617 and the electromagnetic connector 43, the lifting module 616 lifts the mobile robot 41 to the designated height. The electric telescopic rod 67 extends to drive the mobile robot 41 to move horizontally. After the mobile robot 41 passes over the obstacle, the lifting module 616... The mounting module 616 hoists the mobile robot 41 to the ground position and releases the electromagnetic chuck 617 from the electromagnetic connector 43. After hoisting, the preset program inside the control module 52 controls the second motor 514. The second motor 514 drives the lead screw in the lead screw assembly 513 to rotate, causing the lead screw nut in the lead screw assembly 513 to drive the upper limit roller 510 at the corresponding position to move backward in the inner cavity of the guide rail 59. The scissor folding frame 512 folds inward under the limiting action of the pivot seat 511. The scissor folding frame 512 drives the distance between the left and right drive modules 51 to narrow. The left and right drive modules 51 pass through obstacles and move with the mobile robot 41.
