on line testing meaning in English

联机检验

According to the " on board - on line testing " idea , it brings developers a high requirement to construct and design a mini & portable detection system : to power the system using dc ( direct current ) storage battery ; to develop an 110v dc power supply used for control in this system ; to design an intelligent driving loop for hybrid stepping motor based on the main - sub microprocessor group ; to provide workers a friendly interface using the lcd ( liquid crystal displaying ) technology and a mini - keyboard ; to harmonize the whole system using mcu based detection and control cell to provide a high precise platform to the data acquisition , the data analysis , as well as the data saving
基于“上车在线检修”的思想，测试系统的小型化、便携化给系统的选型及构建提出了较高要求：系统采用直流蓄电池供电；研制了内置控制用110v直流电源；设计了基于上下位单片机的智能型混合式步进电机驱动回路；应用液晶显示技术配以小键盘为系统提供了便捷的人机对话接口；以mcu为核心的检测控制单元协调整个系统运作，提供了高精度的数据采集、分析和处理平台。
