Abstract:

In order to solve the problems of scattered layout of the data acquisition system and easily attenuated and interfered signals in the HL-2M diagnostic equipment, a novel ethernet distributed data acquisition system and a management scheme are present. The acquisition module has an ethernet interface, which can be distributed in the remote distance and connected to the local area network easily. The functions of data acquisition, storage, upload and centralized management can be achieved in the centralized management system, which works in the client/server and different levels management mode, through using the technology of multi-thread socket network communication. The discharge experiment tests prove that the acquisition system has the characteristics of accurate measurement, strong anti-interference performance, fast speed data transmission, convenient deployment and management, and can satisfy the data requirement of plasma physics diagnosis system.

摘要：

针对HL-2M装置诊断设备中采集系统布局分散、信号容易衰减和被干扰的问题，提出了一种新颖的以太网分布式数据采集系统和管理方案。采集模块具有以太网接口，能够容易远距离分布式放置和接入局域网。集中管理系统运用多线程Socket网络通信技术，采用客户端/服务端双模式，分不同级别管理采集系统，实现数据采集、存储、上传与集中管理功能。在真实放电实验中测试表明，采集系统具有测量准确，抗干扰性能强，数据传输速度快，方便部署和管理的特点，能够满足等离子物理诊断系统的数据需求。
