车载超短波电台维修检测系统的设计与实现

Design and Realization of Maintenance Test System for Carrier Ultra-short-Wave Radio

针对某新型车载超短波电台原理结构复杂、自检虚警率高、故障定位困难等问题,综合采用嵌入式技术、数据库软件、电路智能检测等技术,以车载超短波电台维修检测主机+模件测试夹具的架构构建硬件平台,研制开发车载超短波电台维修检测系统;该系统能够实现对车载超短波电台整机频率误差、输出功率、接收灵敏度等参数及电台内部模件性能指标的自动化测试,测试结果与标准特征值比对,实现电台整机技术状态评估和模件级故障定位,实现电台维修信息的实时存储与查询,从而解决陆军部队车载超短波电台维修检测手段不足、维修保障困难等实际问题。

According to the complexity of new vehicle’s ultra-short-wave carrier radio’s principle and structure,the height of the rate of false alarm,the difficulty of fault location,adopting technology of embedded-system,software of database and circuit intelligent detection,develop the new on-board maintenance system of ultra-short-wave radio with the hardware platform of maintenance test computer and measurement fixture.Through the new maintenance,automatic testing of parameters such as frequency error,output power and receiving sensitivity is realized.The new maintenance system can accomplish assessment and fault location of the radio,real-time information storage and inquiry,with carrying out property detection on ultra-short-wave carrier radio and its internal modular automatically.The new maintenance system can solve the problem of lack of maintenance’s methods and the difficulty of guarantee of the army vehicle’s ultra-short-wave carrier radio.
