Method for testing thickness of rfid tag with coupled antenna structure and application
ActiveCN121118936Brecord in timeFunctions as a thickness sensor
This invention relates to a thickness testing method for RFID tags using a coupled antenna structure and its application. The thickness testing method includes the following steps: 1) setting up an ultra-high frequency antenna and a metal circuit on both sides of the thickness of the object to be tested, forming an RFID tag with a coupled antenna structure; 2) using an RFID reader to transmit ultra-high frequency electromagnetic waves of a specific frequency to read the information of the RFID tag with the coupled antenna structure; 3) obtaining the maximum reading distance of the RFID tag with the coupled antenna structure at a specific frequency; 4) obtaining the corresponding maximum reading distance for thickness test objects of the same material but different thicknesses; 5) obtaining a linear relationship curve between the thickness of the object to be tested and the maximum reading distance of the RFID tag with the coupled antenna structure; 6) obtaining the thickness of the object to be tested corresponding to the maximum reading distance measured by the RFID reader from the linear relationship curve in step 5). This invention enables the RFID tag with the coupled antenna structure to function as a thickness sensor.

A trackside equipment data processing board
This utility model discloses a data processing board for trackside equipment, belonging to the technical field of subway trackside equipment. It includes a data processing module, a soft-start output module, a power-down voltage monitoring module, an RTC real-time clock module with a first energy storage capacitor, a power supply module with a second energy storage capacitor, and a data interface module. The data processing module is electrically connected to the other modules. The power supply module provides the operating voltage to the board, and its second energy storage capacitor temporarily supplies power to the data processing module during brief external power outages to record the voltage status data at the moment of power failure. The first energy storage capacitor of the RTC real-time clock module maintains clock operation for a preset duration after power failure. This utility model solves the problems of easy data loss and clock failure during power failures in traditional boards. It features high structural integration, stable operation, and accurate recording of power-down fault conditions, meeting the data continuity requirements of subway trackside equipment.

A method and system for monitoring sewage outlets based on unmanned aerial vehicles
ActiveCN121392674BHigh track stabilityImprove track stability
This invention relates to the field of image processing technology and discloses a method and system for monitoring sewage outlets based on unmanned aerial vehicles (UAVs). The method includes: generating a dynamic flight strategy for the UAV based on meteorological information and lighting conditions of the target area; conducting preliminary monitoring of sewage outlets in the target area based on their distribution to obtain effective sewage outlet locations and images; filtering out ineffective sewage outlet locations from the distribution; compensating for ineffective sewage outlet locations using historical pollution data and a pre-set multi-period pollution model to generate a pollution heat map; extracting sewage outlet features from the effective sewage outlet images; marking anomalies in the target area's sewage outlets to obtain abnormal sewage outlet locations; conducting centralized inspections of these abnormal locations to obtain the monitoring results for the target sewage outlets. This invention effectively improves the stability of image acquisition quality, the comprehensiveness of sewage outlet location monitoring, and the accuracy of identification under extreme weather and lighting conditions.

An out-of-box detection system and method for a communication device
ActiveCN115756995BImprove real-time performancerecord in timeDetecting faulty computer hardwareSleep stateSleep function
The application discloses a system and method for opening box detection of a communication device, which mainly comprises a switch module, a clock module, a microprocessor with a sleep function, a storage module and a power module. The method mainly comprises the following steps: judging whether there is an external power input; if yes, the microprocessor enters a sleep state and performs opening box detection in the sleep state; if no, the microprocessor enters a full-function state and performs opening box detection in the full-function state. Through the application, the real-time performance of the opening box detection result can be greatly improved. Moreover, the record of the opening box time includes both power-off conditions and normal operation conditions, so that the record of the opening box detection result is more accurate.
