【摘要】 论述了雷达电源监控系统软硬件基本构成。该系统实现远程监测电源系统各项技术参数，实现电源的良好人机界面及更方便的控制指示。通过对监测数据的分析，实现电源设备故障分析、定位，实现用电设备故障分析、定位。传统的雷达电源监控的设计思想是基于好坏判定，设计者针对该要求只需简单地门限比较后给出一个逻辑电平。这种方法存在一定的局限性，不利于故障分析、定位。为满足监控任务的新要求，论文在分析了几种总线的优点后，在系统设计时充分采用新技术，例如采用隔离RS485总线与数据汇总互联、运用隔离的I~2C总线来连接多路电源内部、应用单总线来实现散热器温度采集的数字化、用PC104来实现监控数据的汇总及与顶层管理级计算机的多接口模式通讯等，这些新技术的应用提升了监控的实时性和通用性，本文对这些技术的应用进行了阐述。更多还原

【Abstract】 The hardware and software fundamental structure of the monitor and control system for power supply in radar has been introduced. This system monitors the technical parameter of power supply remotely, makes well man-machine interface and convenient control display of power supply. Through analyzing the monitor data, achieving the faults analysis and location of power supply devices, achieving the faults analysis and location of power user’s devices.The design idea of the traditional monitor and control system for power supply in radar is based on the stand or fall judgement. The designer ascertain a logical level according to the background and choose the corresponding gate to compare. There is some localization in this kind of method. It will arouse some problems such as achieving the faults analysis and location of power supply devices. By analyzing the benefits of some bus in this paper, new techniques are applied sufficiently in the process of design to meet the new requirements of monitor and control system, such as using isolated RS485 bus to connect power supply and data collection, using isolated I~2C bus to connect multiple outputs power supply inside, using one-wire bus to achieve digital temperature of radiator, using PC104 to make data collection and communicate with the top part for management of computers through multiple connection modes. The real time and generality are upgraded by applying these techniques. This paper expatiates the application of these techniques.更多还原
