摘　　要：采用Nordic公司nRF2401高速无线收发芯片设计了无线数据传输的CCD测量系统,给出了技术解决方案。具有软硬件设计简捷、无需插卡等优点,可使外设工作于PC串口等多种模式下。此方案利用无线数据传输的方式,代替了传统的硬线介质,实现了线阵CCD测量系统与计算机之间的实时数据通信。当射频通信的速率为1Mb/s、250kb/s时,在实验室条件下,10m之内可以保证数据准确可靠的传输。在空旷地带,实现可靠通信的距离可达到40m。A CCD measurement system was designed based on the wireless data communication according to the nRF2401 chip of Nordic Corp. A technical solution was provided. This scheme has many advantages, such as succinct design for software and hardware, needn＇t insert cards etc. , and that also makes peripherals work with multimode, such as serial interface. With the scheme, the new wireless communication technique was adopted instead of traditional cable. The problem of the real-time data communication between the t systems with line-array CCD and computers was solved. The end of CCD measurement was gained in turn. When the speed of RF communication was 1Mbps or 250kbps, the data were transmitted reliably in laboratory. And in open place, the distance reached 40 meters.
