摘要
为解决传统的条码识别器便携性差,且不支持QR二维码识别等问题,文章设计了基于Linux的无线物联QR二维码物品清点器。基于Linux内核制作嵌入式操作系统,移植开源的ZBar二维码识别库作为清点器下的二维码识别库,并采用SSH安全传输协议,以实现清点器与服务器之间数据能够安全、稳定地同步传输。结果表明,清点器可以实时、高效地识别二维码,识别结果可以清楚地展示在软件界面上。该清点器扫码效果好,实用性强,可广泛应用于物资清点等诸多物联网场合。
To solve the problem of poor portability of traditional barcode recognizer and not supporting QR two-dimensional code recognition,a wireless couplet QR two-dimensional code item counter based on Linux was designed.Embedded operating system was built based on Linux kernel.Open source ZBar two-dimensional code recognition library was transplanted as two-dimensional code recognition library under the counter,and SSH secure transmission protocol was adopted to realize data transmission between the counter and the server safely and steadily.The counter can recognize two-dimensional codes in real time and efficiently,the recognition results can be clearly displayed on the software interface.The counter has good scanner effect and practicability,and can be widely used in material inventory,and many other Internet of Things occasions.
