Embodiment Construction

[0033] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0034] Such as figure 1 As shown, the present invention includes two parts: a barcode scanning terminal and a data control program. The barcode scanning terminal communicates with the data control program through Ethernet; Module and storage module, the input of the reading module is the signal for scanning and reading the barcode information, the output is connected to the network module through the control module, and communicates with the data control program, and the storage module is respectively connected with the control module and the network module , the input terminal of the display module is connected to the control module. The barcode scanning terminal runs in an embedded real-time multitasking operating system environment, and is mainly responsible for scanning, decoding, preprocessing, sending data to the upper-level data control program and wa...

Abstract

The invention discloses a bar code recognizer based on Ethernet in the self-control domain, which consists of bar code scanning terminal and data control program, wherein the bar code scanning terminal communicates the data control program through Ethernet, which contains recognizing mode, control mode, internet mode, display mode and storage mode; the input end of recognizing mode scans and recognizes the signal of bar code information, which communicates data control program through control mode connecting internet mode; the storage mode connects the control mode, internet mode separately; the input end of display mode connects the control mode. The invention reduces the cost and improves the transmission speed, which is convenient to use.

Description

technical field [0001] The invention relates to the field of automatic control, in particular to an Ethernet-based bar code reader. Background technique [0002] Existing barcode scanning instruments only have the function of barcode scanning, but do not have the ability to control. They only send the scanned barcode information to the computer through the serial interface, and the computer is responsible for data management and sending operations. It is required to configure a computer for each barcode scanner, so the overall system cost is high, the flexibility and convenience are poor, the transmission rate of the serial interface is also very low, and it is inconvenient to network. Contents of the invention [0003] In order to overcome the shortcomings of traditional barcode scanners such as low transmission rate, high overall equipment cost, inconvenient networking and use, the purpose of the present invention is to provide a brand new barcode reader including item i...
