Through the practice of profile modeling milling machine by digital transformation, the author analyzes characteristic parameters which influences sample-mold precision of measurement. It not only employs discrete B-spline surface approximation of mathematical model for profile modeling measurements, making measurement of the geometric surface parameters orderly and digital, but also achieves a pattern-lump...
Construction of intelligent transportation system is a necessary requirement for the development of transport, and LPR(License Plate Recognition) is an important part of construction of intelligent transportation system, Therefore, the research of license plate recognition method is of importance. The license plate character is recognized by building BP artificial neural network in this paper, it...
The zero shifts caused by accumulative error of open-loop numerical controlling mechanical equipments need to be manually corrected. An optical-mechanical-electrical integration technology included image analyzer, slit image and MCU are applied to constitute of a system for auto zero shift detection and auto zero returning. Firstly we utilize optoelectronic device to detect the work zero point, then...
Pipelining technology can improve clock frequency through shortening the critical path of logic device. However, the complex algorithm of gradient adaptive lattice joint processing (GALJP ) results in its lower work clock frequency. A pipeline optimization approach based on the technology of delay leading transfer is proposed. By approximate treatment to the updated weight coefficients and errors...
In this paper, the optimal parameters of sections and step is decided by the outcome of the astringency and stability of reflectance in gradient adaptive lattice filter. An adaptive gradient lattice joint processing model of 3 sections for noise cancellation was established and simulated using a variety of EDA tools in a FPGA chip. Behavior level, register transfer level and gate level simulation...
Main subjects discussed in this dissertation focus on the tension control. The tension control accuracy has very big influence to the quantity of the finished product. As a result, the tension control in unwinding and winding processes become very important. Because of the scale that the tension request in fiber winding system is small, this paper use magnetic particle brake and magnetic particle...
