PendingCN122281729Aincrease information densityflexible codingComputer hardwareAlgorithm
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.

A high-voltage line suspension clamp stress monitoring and early warning system

PendingCN122282152APut an end to artificial falsification of safety recordsreduce power consumptionEarly warning systemMartensite transformation
This invention relates to a stress monitoring and early warning system for suspension clamps in high-voltage power lines, belonging to the field of intelligent monitoring of high-voltage lines. The system consists of RFID sensing tags installed on the suspension clamps and an inspection RFID reader. The RFID sensing tag integrates a force-sensitive overload memory unit, a tag chip, and an antenna. Magnetostrictive alloy microwires within the unit are connected to the force transmission path. When the tensile force exceeds a threshold, an irreversible martensitic phase transformation occurs, resulting in a permanent step decrease in magnetic permeability. The tag chip detects this change via a magnetic sensing circuit, hardware-locking and rewriting the overload flag in the non-volatile storage area. The reader reads the flag non-contactly to determine the overload history and calculates the real-time tensile force through the antenna resonant frequency deviation. The reader can be equipped with a drone or handheld terminal to automatically record overload information and generate work orders. The backend server integrates the data to achieve lifespan prediction and batch replacement planning. This system is passive, maintenance-free, and tamper-proof, combining overload memory and stress detection to improve the safety and intelligence level of line operation and maintenance.
