In this paper, a variable blast air conditioning system based on vpvt control method is discussed. it is two stages master - slave bus control system. the variable static pressure smart coordinated control algorithm is realized by the master
本文研究了一種基於vpvt控制的變風量空調系統，這是一種二級主從式總線控制系統，主機實現了變靜壓智能協調控制， n臺從機分別對vav實現變風量的溫度間歇式pid批量控制。 -
Design of logic control circuits, device driver and application of the high - speed data communication system based on pci bus are completed. with s5933 bus master ( dma ), bidirectional and high - speed data transmission are realized
本文完成了基於pci總線的雙機高速數據通信系統的邏輯控制電路設計、驅動程序及應用程序的開發，實現了s5933總線主控（ dma ）方式的雙向高速數據傳輸功能。 -
The third part stressed on the design of gantry control print circuit, especially on how to use am85c30 to expand serial port and to realize the master - slave mode multi - point bus serial communication system with the principle gantry control circuit and other subordinate circuits using rs - 485 bus standard. we developed an idea of more tasks and non - occupancy in programming to make sure that the circuit can complete the communication between the gantry control circuit and other circuits within the permissible minimum time in the system
論文的第三部分重點說明了pet系統機電控制部分中主機箱控制板的設計，尤其突出介紹了用串列通信控制器am85c30實現擴展串口，用rs - 485總線傳輸標準實現的以該控制板為主機，機電控制部分其餘子模塊為從機的主從式多點總線型串列通信系統，在軟體設計上引入了一種多任務非佔先式編程的思想，使得該主控制板能夠在系統允許的最小時間內完成與其餘子模塊之間的信息交換。 -
Profibus - dp is one of the international standard field buses which has been on a wider range of application, it is a protocol being in field device control system and dispersal i / o communication. at present, it has become the most popular field bus technology which develops most quickly, been on the widest range of application and own the most brilliant future. in order to keep up with the technical trends and help to spread the application of field bus technology, it is urgent for us to further research on profibus - dp characteristics, to master how to build and configure profibus - dp networks
Profibus - dp （ processfieldbus - decentralizedperiphery ）是目前應用最廣泛的國際標準現場總線技術之一，是一種用於現場設備級控制系統和分散式i / o通訊的協議，目前在工業控制領域中已成為發展速度最快、應用范圍最廣、最有發展前景的現場總線。因此，深入研究profibus - dp的技術特點，掌握網路的構建和配置方法，已經成為順應技術發展潮流，促進現場總線技術推廣應用的迫切需要。
