Description

Technical Field

[0001] The present invention relates to the field of sensor monitoring technology, and in particular to an array-type self-powered encoding and speed detection system and method. Background Art

[0002] With the rapid development of IoT technology, a coding system that enables interconnection between objects and between objects and people has become particularly important. By assigning specific identifiers to devices, coding systems enable interconnection between devices, thereby integrating and sharing information, allowing them to be accurately identified and located within the IoT. This enables the recording of key information such as the device's operating status, production and processing results, and product attributes. By collecting and analyzing this information in real time, companies can promptly identify and optimize production issues, thereby improving production efficiency and optimizing production processes. Furthermore, coding systems can also serve as intelligent sensors that monitor equipment parameters such as vibration and speed in real time. This allows for the timely detection of equipment failures and the resolution of potential maintenance issues, preventing safety incidents and extending equipment life, thereby improving overall production efficiency.

[0003] However, the current encoding and sensing systems that store and transmit IoT information operate independently, making them insufficient for large-scale applications. They are unable to cost-effectively encode devices or objects and sense their operating status. In particular, package diversion systems, which use image barcodes to provide logistics information and rely on visual image analysis and recognition algorithms, still have limitations when dealing with complex scenarios and variable factors.

[0004] For example, patent CN 108229625 A first sets the coding area and coding reference position, and then quickly locates the area where the image barcode unit array of the entire QR code is located, and then determines the reading direction of the barcode unit array and generates coding information. Patent CN 112163442 A uses a multi-angle industrial camera to capture the code pasted on the surface of the package, and uses graphic code detection technology to decode the located graphic code to obtain information about all graphic codes in the image. However, the above-mentioned patents related to IoT coding and recognition are relatively complex and the various systems are independent of each other, which will significantly affect the production process of the entire industrial production system. In addition, the visual recognition system requires high-performance cameras, image processing equipment and advanced algorithm support. The combination of these hardware and software results in slow processing speed and relatively high cost, which further limits the future development of intelligent logistics.

[0005] With the development of microelectronics and information technology, electrical sensing methods have become increasingly popular in the fields of coding and sensing due to their high sensitivity, rapid response, wide applicability, and self-propulsion. For example, patent CN 112134483A utilizes the characteristic that the relative angles of the nanofibers in the two friction layers of an anisotropic triboelectric nanogenerator produce different signal intensities to distinguish coded information and thus encrypt it. Similarly, patent CN 112216198A utilizes the invisible orientation of the nanofibers in the anisotropic triboelectric nanogenerator encoding to create an anti-counterfeiting system, enabling the application of the signal output by the anisotropic triboelectric nanogenerator at the information level. Furthermore, in the field of triboelectric sensing, patent CN 110872425 A combines a modified thermosetting resin, reinforcing fibers, and an inorganic composite filler in specific proportions to create a wear-resistant and high-temperature-resistant triboelectric material. This material is then fabricated into a vibration-type triboelectric self-propulsion sensing system for monitoring vehicle overweight, underweight, or tire pressure. Similarly, patent CN 108802426 A discloses a method for converting the acceleration of a target's vibration into a voltage signal to monitor displacement and velocity. However, these electrical sensing methods also suffer from independent encoding and sensing technologies, resulting in limited application scenarios and the inability to precisely control the electrical sensing materials used.
