摘　　要：针对高速列车是全封闭式的动车,介绍了基于光纤陀螺及三向加速度和Zigbee低功耗无线通信模块JN5139为基础,用于高速列车轨迹测试的无线测试仪设计,详细阐述了光纤陀螺的工作原理及特点、无线通信模块、时钟电路、大容量数据存储系统等功能模块的硬件设计以及相互之间软件逻辑控制。试验表明该测试仪能实现高速列车轨迹检测功能,特别适合于封闭的高速列车的试验,其通讯距离可以达1000米,电池可持续工作72小时,数据存储空间可达1个月,是非常有效的无线测试系统。For high--speed trains are totally enclosed trains, this paper gives an introduction for the wireless test instrument designed for the high--speed train track testing, based on the fiber optic gyroscope, the three--dimensional acceleration sensor and the low--power wire- less communication module Zigbee＇s JN5139. The paper gives detailed description and illustration on the works and the features of the fiber-- optic gyroscope and focuses on the hardware design and the software logical control of each functional module, such as the wireless communi- cation module, the clock circuit, the high--capacity data storage systems and so on. The experiments show that the detection system can a- chieve the performance of high--speed train track detection, especially for closed high--speed train track test, the communication distance up to 1000 m , the battery lasts 72 hours , the data storage space of up to one month , which is very effective wireless test system.
