便携式雷达电源检测维修系统设计

Design of Portable Radar Power Detection and Maintenance System

针对某大型相控阵雷达装备电源系统维修过程中型号多、数量大、维修周期长、检测维修难的问题,设计了一种便携式电源检测维修系统;该系统由FPGA核心板、数据采集板、ePC-K70-Lite-L一体化模组组成,集成维修人员故障维修经验,通过数据处理及故障诊断软件分析采集的电源数据,最终实现对多种类电源故障的快速检测维修;该系统可对该型雷达3大类13种电源实现在线控制、参数读取和赋值,最多同时可对7组电源参数实现在线检测,测试时间由5分钟缩短到10秒内,电源检测准确率达99%以上,不依靠外接电源可连续工作达5小时以上;本系统投入使用4年以来,运行稳定、易于操作维护,检测维修多种类电源达800余次,极大提高了装备的自主保障能力和维修效率,提升了装备的任务执行成功率。

Aiming at the characteristic of multiple models,large quantity,long maintenance cycle,difficult detection and maintenance in the testing and maintenance process of a large phased array radar,a portable power detection and maintenance system was designed to solve these problems.The system is composed of an FPGA core board,a data acquisition board and an ePC-k70-lite-L integrated module.According trouble clearing experience of maintenance,analyzing the collected data of fault diagnosis software,fast detection and maintenance of multiple kinds of power supply failure are supported.The system can realize online control,parameter reading and assignment of 13 power supplies of three types of a certain type of radar,and can realize online monitoring of up to 7 groups of power parameters at the same time.The test time is shortened from 5 minutes to less than 10 seconds,and the power detection accuracy rate is up to 99%,without relying on external power supply,work continuously for more than 5 hours.Since the system has been put into use for 4 years,it has been stable in operation and easy to operate and maintain.It has tested and repaired various types of power supplies for more than 800 times,which has greatly improved the equipment s independent support capability and maintenance efficiency,and improved the success rate of equipment mission execution.
