摘要
为满足铁路提速列车对测速的要求,采用全天侯8 mm波长一体化传感器及新型嵌入式微处理器等关键技术,研制了一种新型列车测速雷达装置。该装置由测速雷达主机、电源、打印管理器和测速信息管理系统等组成,应用多谱勒效应、同步门控测频基本原理和方法,实现了从普速列车到高速列车准确、快捷测速的监控。经实际测试表明,该装置达到了预期功能和设计目标。
In order to meet the demand of measuring the speed of trains for speeding up railway system,by adopting weatherproof 8 mm wavelength integrated sensor and the technology of embedded microprocessor;the new type of speedo radar is researched and developed.The device is composed of main machine of speedo radar,power supply,printing management,and speed information management system.With the principle and method of Doppler effect,synchronous gate control frequency measurement,accurate and rapid speed measurement and monitoring for ordinary trains to high-speed trains are implemented.Having been tested and improved through practical operations,the device reaches predictive functions and design target.
