In order to improve the efficiency of data acquisition in large-scale scientific experiment, a web-based integrated control software platform is developed to realize the remote centralized control for various types of digital oscilloscopes. A unified hierarchical system structure is proposed to reduce the developing difficulty and increase the extensibility, which divides the system into six layers—the device layer, the hardware device driver layer, the device abstraction layer, the FEP(Front End Processor) device service layer, the application service layer and the presentation layer. The new type of digital oscilloscope can be added to the integrated control software platform easily by developing a driver interface, and it is the same to other diagnostic equipments, such as DAQ(Data Acquisition) card and scientific grade CCD(Charge coupled Device) camera. The application of this system shows that, the system integration method introduced in this paper is suitable for large-scale physics experiment data acquisition and control system, and the web-based integrated control software platform can improve the operation efficiency of experiment significantly.
