According to the surveys of many chinese herbal medicine manufacturing enterprises , the paper designs the production management system , and describes the functions and architecture of its six subsystems including planning management , workshop management , purchase management , inventory management , middle inventory management , equipment management , as well as the relationships among the subsystems 根据国内众多中药制造企业的生产实际，对中药生产管理系统进行了总体设计。此系统由生产计划管理、车间管理、采购管理、库存管理、中间站管理及设备管理六个子系统组成。论述了各子系统的功能以及相互之间的关系。
The functions of this automation system focus on five aspects : data acquisition 、 supervision and control 、 fault isolate and recovery 、 gis 、 data statistic and report . the design project takes the rcs - 9000 series 、 sd ? 9520 and sd - 9630 , which is a new installation that can detect the operation state of the low - voltage current breaker , and send the state to the control room . the other new installation is sd - 9860 , which is the monitor of the cable fault 设计方案中，在采用南瑞rcs - 9000系列、双电公司sd - 9520装置的同时，采用了新开发的sd - 9630塑壳开关运行状态采集装置，检测塑壳开关的运行状态，并将运行状态传回到集控中心（中间站） ；采用了新开发的sd - 9860电缆故障指示器，完成电缆故障的识别；集控中心的设计实现了整个小区配电自动化系统的集中通讯、实时监控、统计与管理功能；高、低压开关实现了自动控制、状态检测和无功补偿等。
This paper first analyzes the characteristics on train working diagram of urban rail transit , on the basis of describing property on rail line of urban rail transit , this paper puts forward theory of two stations drawing and three stations drawing which taking the setting of vehicle depots as the core of the subject designs sequence and contrary advance calculating methods to calculate the train arrival and departure time at mediate station , and builds mathematic model on the train working diagram of urban rail transit taking same interval time of train traveling as the target function 摘要在对城市轨道交通线路属性进行数学描述的基础上，以车辆段设置地点为核心，提出两站图及三站图理论，设计分层顺序和反序推点算法计算列车在中间站的到发时刻，并以分时段列车等间隔运行为目标函数，构建城市轨道交通列车运行图通用数学模型。
