Configuration Soft Applying In Building Control System

Configuration software, which is used for data acquisition and process control in the industrial special field. It works on the control layer of automatic control system,supplying software platform and development environment, provided nice development interfaces and simple use methods to users.After haveing done deep research on the status and existing problems of the existing configuration software, I further clarify the significance of this issue. This paper describes the key technology used in the building control systems and their key technology how to design, applications, and achieve in the building control configuration software system. My main work is summarized as follows:(1) Research on the current domestic and international mainstream configuration software technology; Describe the current situation and existing problems of the configuration software. After analyzeing and basis comparing between the field of PLC industrial and DCS integration technology, finding more significance on this research.(2) According to the building control system development process, preparing of related papers. Details the various functional modules to achieve the key technologies used in the process, as well as the specific design, applications, and achieve.(3) Design and develop the building monitoring control system:graphical interface module, database module, network communication module, web-side modules and scripts interpreted language modules.In this paper, I have completed the above3parts of the designment and development work. The system uses an four-layer structure:Field Data Acquisition OPC Server、 Real-Time Database> Data Management Layer. The system also completes Expand Web Access Function. The data acquisited by Field Data Acquisition uploads to the OPC Server. Real-Time Database conducts as the OPC Client, getting the latest data (the real-time status of field devices) on the OPC Server. Compared with the traditional monitoring system, OPC server shields the difference of the underlying communication protocols, so that the system may need use other different field bus technology, and ensure the collection devices plug-and-play. WEB access management greatly facilitates remote access, and efficiency of the system.
