Industrial Control Summary: As an important component of modern machine automation, machine vision systems serve as the primary tool for perception within the entire machine system.
An embedded system is an embedded processor control board whose control program is stored in ROM; a machine vision system uses machines to replace human eyes to perform various measurements and judgments. It integrates technologies such as optics, mechanics, electronics, and computer hardware and software, and involves multiple fields such as computers, image processing, pattern recognition, artificial intelligence, signal processing, and opto-mechatronics.
National Instruments (NI) recently released a new embedded machine vision system that helps manufacturing engineers and system integrators quickly build high-speed, real-time machine vision systems for applications such as product sorting, assembly verification, and packaging inspection. The NIEVS-1464RT embedded machine vision system features a high-performance multi-core controller capable of processing images from multiple IEEE 1394 and GigE cameras. Furthermore, the EVS-1464RT's wide temperature range, real-time operating system, solid-state drive, and fanless design make it ideal for use in harsh industrial environments.
"In our industrial inspection machines, we prefer to use embedded devices with real-time operating systems, which do not require IT support because they offer better independence and reliability. By standardizing NI's embedded machine vision systems, we can achieve the multi-core performance of industrial PCs while retaining the reliability and security of real-time embedded systems."
The EVS-1464RT offers a variety of camera connectivity options, allowing engineers to use a wide range of cameras to perform simultaneous inspections from high-resolution area scanning to high-speed line scanning, and from color to infrared. The EVS-1464RT also...
It includes a variety of digital I/O and industrial communication options, enabling the system to communicate and integrate with automation equipment such as programmable automation controllers, programmable logic controllers, human-machine interfaces, sensors, and actuators, thereby achieving faster detection.
The EVS-1464RT can be configured using NI Vision Generator for Automated Inspection (VBAI), an interactive software environment that allows for the creation, benchmarking, and deployment of machine vision applications without programming. This intuitive, menu-driven software enables engineers to build complex machine vision applications that not only incorporate image processing algorithms but also utilize the built-in state graph editor for advanced decision-making with loops and branches. For more advanced applications, the EVS-1464RT can be integrated with LabVIEW graphical system design software and the NI Vision Development Module (NDM), which is essentially a comprehensive library of image processing functions. Because both software packages are compatible with all NI machine vision hardware, engineers can easily manage and maintain multiple hardware systems, select appropriate hardware for new applications, and switch between the two software packages with minimal overhead.
