基于COTS的拖靶测控台设计

针对拖靶系统测控台多功能、高可靠、小质量、小体积、低功耗、低成本的要求，采用商用的现成产品（COTS）设计了拖靶测控台。该设备以PC/104为基础，构建了系统硬件工作平台，对CPU、I/O、GPS、数传电台、电源等模块进行了选型设计。以商用DOS系统为底层操作系统，实现了指令采集与状态显示、指令容错编码、实时大数据量接收与存储、数据下载与程序装订等功能。综合运用中断、多级缓冲等机制，实现了系统的正确可靠运行。试验表明系统功能完善，满足拖靶测控台的设计使用要求。

Design of the Control and Telemeter Device of Towed Target based on COTS

The control and telemeter device of towed target is designed based on COTS to meet the requirements of multi-function, high quality, small mess, small scale, low-power and low cost. Its hardware platform is constructed on the base of PC/104 and the unit of CPU, I/O, GPS, data transceiver, and power supply are type selected. The function of instruction collection and display, instruction fault tolerance, real-time large quantity data receiving and saving and data download and program install are realized on the base of commercial DOS operating system. The ISR and multi-grade-buffer are used to make the system work properly. The experiments show that the system functions perfectly and it meets the design and appliance requirements of the control and telemeter device of towed target.
