Linear scanning data wireless transmitting-receiving method

Abstract

The invention relates to a linear scanning data wireless transmitting-receiving apparatus and method, which can transmit the data after scanning and identifying picture, text or bar code by wireless mode. Wherein, the apparatus comprises a wireless communication device, a line scanner, and a connecting component; the connecting component includes a scanning starting drive and a power switch circuit; the scanning starting drive is connected with the GPIO1 input / output port of a main processor contained in the wireless communication device; the enablement terminal of the serial peripheral equipment interface SPI of the main processor is connected with the signal input terminal VIN of the line scanner by a power switch circuit; the synchronized clock signal CLK of the serial peripheral equipment interface SPI is directly connected with the clock port CLK of the line scanner; the line image scanning staring pulse SP from the general input / output interface GPIO2 of the main processor is directly connected with the line image scanning staring pulse signal input terminal of the line scanner; the digital line scanning output signal VOUT output by the line scanner is directly connected with the serial peripheral equipment interface SPI.

Description

technical field [0001] The present invention relates to scanning technology, in particular to a linear scanning device and method capable of wireless transmission and reception, specifically a linear scanning device capable of reading, storing, identifying or decoding graphic or barcode information and sending it through a wireless communication network. Background technique [0002] Nowadays, the application of wireless communication technology is very popular, the information exchange between users is extremely frequent, and the capacity is getting larger and larger. The existing manual input information communication and voice communication cannot meet the requirements of timeliness, high capacity and high accuracy. Currently widely used scanners are generally used in conjunction with computers, and the scanned information can only be uploaded or transferred through the computer, which brings great inconvenience to users.
