摘　　要：针对飞行设备内部各种传感器的数据传输方式为有线传输现状,无形中加大了布线安排、体积增大、成本增加以及无法实时获取数据和数据质量低等问题,设计一种基于CC3200的WiFi数据传输模块。该模块以FPGA作为主控核心单元,并辅以滤波电路、模/数转换电路,最终通过CC3200将处理好的数字信号数据发送给控制中心。经过试验,测试结果符合具体预定要求并且性能稳定、可靠,没有出现数据丢失的情况,现已成功应用于某航天测试系统中。In allusion to the problems such as increase of wiring arrangement, volume and cost, inability to obtain data in real time and low data quality with wire transmission as the data transmission mode of various sensors in flight equipment, a new WiFi data transmission module based on CC3200 is designed. The module takes FPGA as the core unit of main control, is supplemented with the filter circuit, analog-digital conversion circuit, and finally sends the processed digital signal data to the control center by means of CC3200. A test was carried out. The test results show that the system can meet the speeific pre- defined requirements, and has stable and reliable performanee without data loss. The system has been sueeesstidly applied to an aerospace test system.
