Abstract
Goods identification technology after years of development have become more
mature, has been infiltrated into the commercial, storage, post and
telecommunications, transportation, library management, medical and health,
industrial production process control and military equipment, the project, such as the
national economy and people of all walks of life day-to-day life. Automatic
identification technology is based on computer technology and communication
technology based on the development of a comprehensive multi-disciplinary science
and technology. At present, the bar-code technology is the most mature, most
applications of a wide range of automatic identification technology.
Configuration software is accompanied by the rapid advances in computer
technology developed. With the popularity of personal computers and open systems
(Open system) to promote the concept, based on personal monitoring system showing
a smart, small, network-based, PC-based development trends, and gradually formed a
variety of standard network architecture, hardware norms. Configuration software in
the automation system of "horizontal" and "vertical" integration plays a role of bridge
and tie, has become an important automation system components.
The system-based software and PLC Kingview general combination of bar code
reader system of automatic identification of goods, given the structure of the system,
software design and configuration process. The use of PLC as the next-bit machine to
improve the signal and control signal acquisition accuracy, and can modify the
program site, to facilitate maintenance. The use of configuration software, users can
easily adapt to their needs the structure of the "Data Acquisition System", to achieve
real-time data monitoring and management to ensure that information flow within the
scope of the whole in order to adapt to the needs of modern production.
Key words：PLC, Bar-Code Reader, Configuration Software
