It collects and stores data from each subsystem. However, the complexity and high coupling of the system make it vulnerable to failure. If one module malfunctions, it can cause the entire system to collapse, hindering future maintenance and expansion. To address this issue, this paper proposes a data acquisition and management system based on the PCI-1706 multi-channel synchronous data acquisition cards and the MDSPlus database, along with a data Scope program. The data acquisition system employs a multi-process design to achieve synchronization among multiple channels by using an external clock and trigger signal. Meanwhile, the data management system utilizes MDSPlus, and a client Scope program is developed to enable remote data access and analysis. The reflection memory card is employed to establish a network for data interaction between the server and the acquisition machine, enhancing storage speed. Experimental tests have confirmed the multi-card and multi-channel synchronous acquisition functions of the data acquisition system, as well as the remote data access capability of the Scope program. This system exhibits advantages such as low cost, simple structure, stable operation, and easy maintenance. It proves to be effective in Tokamak device experiments and can also serve as a reference for other data management systems.</p>","PeriodicalId":587,"journal":{"name":"Instruments and Experimental Techniques","volume":"67 5","pages":"892 - 901"},"PeriodicalIF":0.4,"publicationDate":"2025-02-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143108244","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
