Two-wire system electronic tag assisted order-picking system

Abstract

The invention relates to a novel electronic tag assisted order-picking system, in particular to an electronic tag order-picking assistant system based on two-wire system communication buses. The electronic tag assisted order-picking system comprises an upper computer, a plurality of controllers and a plurality of application terminals. The electronic tag assisted order-picking system is characterized in that the upper computer is used for accomplishing generation of orders and controlling the electronic tag assisted order-picking system, a TCP / IP network communication protocol is adopted between the controllers and the upper computer, three-channel output is adopted by each controller, the two-wire system communication buses serve as buses of channels, the application terminals are electronic tags, communication junction is achieved between the electronic tags and the channels of the controllers through the two-wire system communication buses, and the electronic tags analyze signals on the two-wire system communication buses, and achieve the function of fault diagnosis, the function of LED indication, the function of digital display and the function of scanning of the states of keys according to the analyzed signals. The whole electronic tag assisted order-picking system is controlled through the upper computer, and thus the picking operation becomes quite simple, labor intensity is reduced, working efficiency is improved, the accurate rate of picking is improved, and paperless operation of picking of a warehouse is achieved.

Description

technical field [0001] The invention relates to a novel electronic tag-assisted picking system, in particular to an electronic tag-assisted picking system based on a two-wire communication bus. Background technique [0002] As early as the 1970s, the western developed countries had already started to apply the logistics distribution system, and the logistics distribution system was widely used in the 1990s. In particular, the development and application of automated logistics and distribution are mainly due to the rapid development of two technologies in terms of technology: one is the development of microelectronics technology, that is, computer technology, automatic control technology, digital identification technology, photoelectric technology The second is the development of computer software technology, mainly database technology, network technology and information system technology, which constitute the so-called hardware and software support environment. [0003] The...
