摘　　要：传统有线条码扫描仪受数据线长度的影响,而市场上的无线条码扫描仪无线通信距离一般在30～100 m范围内,在使用范围和用途上造成一些限制.提出一种基于嵌入式的无线扫描系统的设计,其最大无线通信距离为800 m.该设计采用Philips公司的LPC2142 ARM嵌入式芯片和ADI公司的ADF7020无线收发芯片.LPC2142接收条码扫描仪采集的数据并进行处理,ADF7020完成无线数据发送接收.The traditional bar code scanner has influence on the length of data line, but the farthest distance of the wireless bar code scanner＇s wireless communication is generally between 30m and 100m on the market. Therefore,it causes some restrictions in terms of usage sphere and function. This paper mentions a design of embedded wireless bar code scanner which the farthest wireless communication distance is 800 m, the design adopts the LPC2142 ARM embedded chip of Philips corporation, and the ADF7020 wireless receiving/dispatch chip of ADI corporation. LPC2142 accepts the data that bar code scanner collected and handle it. ADF7020 achieves deliver acceptance of wireless data.
