脉冲强磁场测量数据实时远程传输系统的设计与实现

摘要

针对脉冲强磁场装置中放电磁感应强度、放电电流等重要测量数据的实时共享和跨软件平台传输的需要,设计了基于TCP/IP通信协议的脉冲强磁场测量数据实时远程传输系统.其服务器位于实验站,软件平台为LabVIEW,完成数据的本地测量、高速采集和实时传输；客户端位于控制室的主控程序,由Visual C++编写,完成实验站的录波启动、数据采集触发等控制功能,并实现服务器端传输数据的实时显示和存储.在传输系统的设计中,采用了心跳、预触发和分组传输等机制,保证在强磁场环境下实现采集数据的远程实时、可靠传输.测试表明,该系统可在2 s内将所有波形数据可靠地上传到主控程序.%A real-time remote data transmission system of a pulsed high magnetic field facility based on TCP/IP protocol was designed to provide real-time sharing and cross-platform transmission for key measurement data,such as magnetic induction intensity and discharge current.The server of the system,located at the experiment station and developed with LabVIEW,mainly performs the functions of local measurement,high-speed data acquisition and data transmission in real-time.The client of the system,located at the control room and developed with Visual C + +,was designed to perform the functions of enabling and triggering waveform record,and real-time display and storage of the data from the server.Heartbeat,pre-trigger,segment transmission and some other mechanisms are taken in the transmitting system to ensure that remote data can be transmitted reliably and in time.The tests indicate that the system is reliable and the transmission speed is fast.
