In this paper, the RFID system and its related technologies are introduced, and the inevitable tags collision problem in RFID technology is analyzed. At the basis of an in-depth study on the popular ALOHA algorithm and binary search algorithm to solve the tags collision problem, the basic principles and a variety of improvements of the two algorithms is described in detail, and the emergence of new...
In this paper, a mechanical condition monitoring system of Molded Case Circuit Breaker (MCCB) is designed and developed. The operation principle of the monitoring system, the hardware design and the software design are introduced in detail. The three-phase voltage, the voltage between auxiliary normally closed contacts and the motor current are detected during the opening operation, closing operation...
In order to eliminate the shortcomings in apple color grading, such as the slow speed, the large error, a novel fast intelligent grading method is presented, which is based on the improved particle swarm optimization (PSO) algorithm and Support Vector Machine. The main process is to acquire the colority of apple surface by the computer vision technology and extract its features which used as the samples...
The design uses a dual CPU DSP + MCU Design AGV motion control system, DSP chips, as machine vision signal acquisition and processing core, The design of the Image Acquisition using the DSP / BIOS operating system, the preparation of the image coding chip TVP5150 driver, in the application of image conversion and recognition, and the corresponding optimization algorithm to identify the results transmitted...
Residual current protective devices play an important role in electrical safety engineering. Under normal conditions, it is discovered that there exists leakage current during power transmission and it can change dramatically due to insulation fault or electrical shocks. Possible reasons for leakage current in power system are analyzed. Efforts have been made to monitor such leakage current. A residual...
