摘要
依据化工设备设计企业管理工作流程,建立系统的基本流程框架——以工程项目为基本单位进行管理,对项目按装置、主项、次项和设备的顺序树状逐级分解,在被分解数据的基础上建立与主项、次项和设备相对应的工作项,基于工作项进行工作安排、工作量统计及奖金分配等工作。软件由系统管理、项目管理、奖金分配、统计、文件输出及考勤管理等模块构成,实现了化工设备设计工作管理的核心业务流程。最后讨论了以菜单权限和文件权限共同作用的方式,满足不同级别用户对系统登录和文件操作的需求。
A multi-channel real-time acquisition circuit was designed for telemetry data, which takes FPGA as controller to acquire multi-channel analog signal by applying time-capture technology; meanwhile, for the dis- tortion phenomenon in analog signal sampling process, effective positioning analysis was taken for the abnormal phenomena in the analog signal transmission, and hardware circuit design for improving analog signal condi- tioning was proposed, and real-time sampling control timing was optimized for a 0.1% sampling accuracy and the stability of real-time acquisition system.
