The system realizes multiple serial port communication and management by way of multi - port serial board ( 2 ) use the database technology to manage and manipulate the physics information data of nc tool. the basic information management system, the nc program auto - create system, the simulation of cutter working and dnc communication program are integrated to one system. it realizes the offline programming and controls of no - punched tape, helps to cut short the supplementary cutting time and improves the efficiency of to program and machine tools and realizes the separation and seamless connection of program and manufacture
本課題以硬體為輔助手段,以軟體為主要手段實現了以下功能:以串口擴展卡來實現網路中多臺數控機床的通信和管理;使用數據庫技術對數控機床的物理信息進行管理和操作,將數控機床基礎信息管理系統、 nc程序自動生成模塊、刀具加工軌跡模擬模塊和dnc通信介面模塊集成為一體,實現了數控加工的離線編程和數控系統的無帶控制,提高了編程效率、質量,縮短加工輔助時間,提高了機床的效率,既實現了編程和加工的分離,又達到它們之間的無縫連接。Abstract : this article retrospects the development of sequence control system in thermal power plants at home and abroad , especially introduces the three developmental stages of sequence control system in china over the past 35 years , i. e. : 1. starting stage ; 2. the second stage with programmable logic controller ( plc ) as core hardwares ; and 3. the third stage with sequence control systems of main and auxiliary equipment incorporated into the distributed control system ( dcs ) and with field bus control system ( fcs ) got involved. this article also appraises the features of sequence control system composed of different configurations and looks forward to the developmental tendency of this system for the next century
文摘:回顧國內、外火電廠順序控制系統的發展,特別介紹35a來我國順序控制系統經歷的起步階段、以程序控制器( plc )為核心硬體的中期階段和主、輔機順序控制系統融入分散控制系統( dcs )階段、現場總線控制系統( fcs )介入階段,並對由不同形式組成的順序控制系統的特點進行評價,展望下一世紀該系統的發展趨勢。Secondly, the main stuctures of the software and hardware parts of the control system are introduced. principles and realization of the main functional blocks of these two parts are illuminated. on the hardware of the system, parts of control circuit and the design and debugging of peripheral circuits are discussed thoroughly. based on the hardware circuit, the software is programmed with assembly language. dual close loop vector control weth feedback of speed and current are realized. the flow charts of main programme and pwm interrupt service routines are given. the important control strategies of vector control pmsm such as current sensint and scaling, speed sensing and scaling, bector co - ordinate transformation, generation of sine and cosine, pi regulators, svpwm vector modulation and so on are all accomplished in the pwm interrupt sevice routines. in order to unite all the variables in the programme, scaling is used
硬體方面主要論述了控制電路各部分及外圍輔助電路的設計和調試。在硬體的基礎上,軟體採用匯編語言編程,實現了轉速和電流雙閉環矢量控制。給出了系統主程序和pwm下溢中斷處理程序流程圖, pmsm矢量控制的主要控制策略如電流采樣與定標、速度采樣與定標、矢量坐標變換、 sin和cos值生成、 pi調節、 svpwm波形生成等都是在pwm下溢中斷服務子程序中完成的。
