【摘要】:随着经济全球化进程的加快,现代物流行业呈现出稳步增长的态势,,条码技术在货物管理中得到广泛应用。市场对于无线条码采集终端的需求日益凸显。就目前来说,将几种无线通信方式集中在一起的条码采集终端比较少,而且价格昂贵。另外,在传输条码数据过程中,没有对所采集待发送的条码数据进行有效的加密,容易造成条码数据的外泄。本文针对上述情况,设计和实现了一种无线条码采集终端,将GPRS和WiFi两种无线传输方式集成到一起,并对条码数据信息使用DES算法加密,有效地解决了这两个问题。 本文基于S3C6410处理器设计了核心板电路,根据具体的功能需求和实现目标,采用SIM300C GPRS模块和WM-G-MR-09WiFi模块设计了无线传输模块外围接口电路,为系统搭建了硬件开发平台。在此基础上,选用Windows CE6.0嵌入式操作系统作为软件开发平台,开发了与硬件平台相关的板级支持包(BSP),包括BootLoader、OAL和驱动程序,定制了Windows CE6.0操作系统,导出应用软件开发所需要的软件开发工具包(SDK)。之后设计与实现了相关模块的应用程序,包括串口通信模块、DES加解密模块、GPRS通信模块、WiFi通信模块和用户界面模块等。 本次开发的无线条码采集终端可以使用GPRS或者WiFi无线传输方式将采集到的条码数据传输到远端服务器,并在传输过程中实现了对条码数据的有效加密,保证传输数据的安全性,达到了预期的目标,具有较好的实用价值。
[Abstract]:With the acceleration of the process of economic globalization, the modern logistics industry has shown a steady growth, and the barcode technology has been widely used in the management of goods. The demand of the market for wireless bar code acquisition terminals is becoming more and more prominent. In the present case, the bar code acquisition terminals in which several wireless communication modes are concentrated are less, and are expensive. In addition, in the process of transmitting the bar code data, the bar code data to be transmitted is not effectively encrypted, and the leakage of the bar code data can be easily caused. In this paper, a wireless bar code acquisition terminal is designed and implemented, and the two wireless transmission modes of GPRS and WiFi are integrated, and the two problems are solved effectively by using DES algorithm to encrypt the bar code data information. The core board circuit is designed based on the S3C6410 processor. According to the specific functional requirements and the goal, the peripheral interface circuit of the wireless transmission module is designed by using the SIM300C GPRS module and the WM-G-MR-09 WiFi module, and the hardware development level is set up for the system. On the basis of this, the Windows CE6.0 embedded operating system is selected as the software development platform, and the board-level support package (BSP) related to the hardware platform is developed, including the BootLoader, the OAL and the driver, and the Windows CE6.0 operating system is customized, and the software development kit (SDK) needed for the development of the application software is derived. and then the application program of the relevant module is designed and implemented, The wireless bar code acquisition terminal developed by the invention can transmit the acquired bar code data to the remote server by using the GPRS or the WiFi wireless transmission mode, the target of the invention has the advantages of good real-time performance,
