飞利浦彩超EPIQ7C结构原理及电源故障检测

摘要

In this paper, the working principle of philips color ultrasound named by EPIQ7C and the software and hardware process of power startup were introduced in detail firstly. Then, the detection of power failure was mainly discussed in combination with the equipment failure condition. By analyzing the voltage threshold of power module interface connection diagram and power module, the isolation detection method of power failure was discussed. It provided strong data and theoretical support for the power modular maintenance of EPIQ7C.%本文首先详细介绍了超声发射前端和后端主机的各个模块构成及各个模块的功能,接着介绍了飞利浦彩超EPIQ7C开机信号工作原理及电压启动后设备开机的软硬件流程.结合设备整体故障情况分析,重点阐述电源故障的检测.通过分析其电源模块接口连接图及电源模块各组电压阈值,探讨了其电源故障的隔离检测方法,为EPIQ7C彩超电源模块化维修提供强有力的数据和理论支持.
