Two-dimensional code integrated sensing label system for monitoring multiple physical quantity parameters in real time and preparation method thereof

Abstract

The invention discloses a two-dimensional code integrated sensing label system for monitoring multiple physical quantity parameters in real time and a preparation method thereof, and the system comprises:, and a two-dimensional code integrated sensing label, which prints color-changing ink for sensing temperature, humidity, gas, pressure and the like on designated sub-areas of a two-dimensional code pattern respectively, and forms simultaneous sensing of multiple physical quantities, wherein the color of each sub-region of the two-dimensional code integrated sensing label is changed according to the change of the temperature, humidity, gas and pressure of the surrounding environment; and a two-dimensional code APP, wherein the two-dimensional code is scanned through intelligent equipment, color characteristics of each sub-region are obtained by using a color model, and real-time temperature, humidity, gas, pressure and other physical parameter values are identified based on region color changes. Physical parameter color information obtained during scanning is stored or analyzed and processed through a two-dimensional code APP, coding information of a two-dimensional code and real-time environment parameter values are displayed on intelligent equipment at the same time, sensing data integrated analysis and processing are conducted through the neural network technology, and the real-time prompting and early warning function is achieved.

Description

technical field [0001] The invention relates to the technical field of two-dimensional codes and sensors, in particular to a two-dimensional code integrated sensor label system for real-time monitoring of multiple physical quantity parameters and a preparation method thereof. Background technique [0002] At present, two-dimensional codes are widely used in packaging, but the two-dimensional codes on most packages only have the function of storing simple information, and managers or users cannot obtain product environmental information and information from existing packaging two-dimensional codes. change information. Therefore, how to detect and transmit changes in environmental parameters in real time during packaging storage or transportation at low cost and conveniently is crucial to the quality monitoring and safety of packaged products. The application of two-dimensional codes in anti-counterfeiting, traceability and other fields has been relatively mature. Expanding ...
