The application provides a pre-tailings discarding mode distinguishing method based on useful mineral dissemination characteristics, and relates to the field of mineral processing. The pre-tailings discarding mode distinguishing method based on useful mineral dissemination characteristics comprises the following steps: preparing a plurality of optical sections from an ore sample; analyzing the optical sections by using an optical microscope and an image analysis technology, and classifying the dissemination characteristics of useful minerals in the optical sections; calculating the average occupancy of local enrichment type in all optical sections, the average occupancy of vein type in all optical sections, and calculating a pre-enrichment proportion Pvalid; comparing the pre-enrichment proportion with a preset threshold value, and if Pvalid is greater than or equal to the preset threshold value, it is determined that the ore sample is suitable for pre-enrichment by using a pre-tailings discarding process. The prediction conclusion of the method of the application is highly consistent with actual industrial test and production data, has the advantage of high accuracy, solves the problem that the pre-discarding effect can only be detected by test, and is beneficial to improving work efficiency and reducing cost.

This invention discloses a method for encoding structured light patterns, a structured light projection module, and a three-dimensional measurement system, belonging to the field of optical measurement. Addressing the problem of fixed and inaccurate structured light encoding units in existing methods, this invention provides a method for encoding structured light patterns. The method divides the structured light pattern into multiple types of grid units, forming a grid encoding group with a predetermined number of consecutively arranged grid units. The grid encoding group is encoded based on the type of each grid unit, ensuring that each grid encoding group has a unique and non-repeating code. The code of the grid encoding group maps to its spatial position within the structured light pattern. Decoding includes acquiring the structured light pattern, determining the type of each grid unit, and matching the grid encoding group with the encoding set to obtain its position. This invention achieves flexible, high-density, and highly occlusion-resistant absolute position encoding by uniquely and non-repeating grid encoding groups composed of multiple consecutive grid units, making it suitable for high-precision three-dimensional measurement.

This invention discloses an automated reference volumetric measurement system and method for performance evaluation of a water electrolysis hydrogen production system, relating to the field of gas flow metering and performance testing. The system includes: a main inlet pipe, a main outlet pipe, multiple reference measurement units connected in parallel between the two, an intelligent fluid switching matrix for controlling gas flow and direction, and a controller electrically connected to the reference measurement units and the intelligent fluid switching matrix. The reference measurement units are used to collect temperature-time series data and pressure-time series data in real time. The controller controls the valves in the intelligent fluid switching matrix to operate according to a predetermined sequence, enabling the multiple reference measurement units to perform cyclic relay volumetric measurements within the evaluation period. The average flow rate within the evaluation period is calculated based on the temperature-time series data and pressure-time series data collected by each reference measurement unit in each cycle. This invention enables automated, high-precision measurement in high-flow-rate scenarios.
