A High-Speed Data Acquisition and Control System Based on LabVIEW for Long-Pulse Experiments

It is well known that energy has become one of the essential factors for the development of human civilization. As a new type of energy source, fusion energy is considered to be the most promising and effective way to solve future energy problems. With the continuous research in this field, the current types of pulse experiments have gradually developed into long-pulse experiment operation mode. This paper designs a data acquisition and control system (DACS) in order to meet the requirements of high-speed data acquisition and efficient storage in the context of long-pulse experiments. This system designs a new data transmission and storage management mode to enable the interaction between LabVIEW and MDSplus, making it suitable for multi-channel high-speed data acquisition experiments in long-pulse mode. Besides, DACS uses MDSip and HTTP network communication protocols to transmit control signals and experimental data. As for human-machine interaction, it adopts a combination of local and remote interactions to satisfy the requirements of different situations. It also devises a suitable algorithm to solve the concurrent processing problem of double platforms. The design of this system can accomplish the tasks of monitoring and control as well as real-time processing and storage of experimental data in long-pulse experiments, improving the overall level of automation of the system.
