基于Android的二维码食品药品回溯系统

为便于消费者查询所需食品和药品的详细信息,提出了基于Android的二维码食品药品回溯系统。采用快速响应(QR: Quick Response)矩阵码, 对信息中汉字进行准确编码, 基于Android 4.0.3嵌入式硬件开发平台, 实现识别界面和显示界面等功能界面的设计。通过无线网络与MySQL(My Structured Query Language)数据库进行数据传输, 实现信息查询、 录入等操作。测试结果表明, 在二维码扫描过程中该系统具有良好的抗干扰性, 在以最大旋转角45°对二维码进行扫描时, 仍可对信息进行有效识别。同时依托Android系统较强的移动性, 该系统可得到更广泛的应用。

QR Code Backtracking System of Food and Medicine Based on Android

In order to meet the demand of consumers searching the information about food and medicine, a QR （Quick Response） code backtracking system of food and medicine based on Android is proposed. To realize the Chinese characters encoding, a kind of two-dimensional technology called QR code is used. The system applies Android 4. 0. 3 embedded system as its hardware development platform to implement QR code recognition interface, display interface, etc. The functions of information inquiring and inputting based on Android are achieved by realizing Language scanning. ） database When we And the system can the data transmission between wireless network and MySQL （My Structured Query Test results show that the system has a good anti-interference in the process of QR code scan a QR code with maximum rotation angle 45°, we still can get the useful information be widely used relying on the strong mobility of Android.
