Abstract:

With the widespread application of nuclear magnetic resonance (NMR) technology in fields such as food safety inspection and petroleum exploration, there is a growing demand for miniaturized and portable NMR spectrometers. In response to this demand, this paper proposes a system design framework for a palm-sized NMR spectrometer console and develops a comprehensive and flexible software architecture. The software system consists of two main components: embedded control software and host computer application software. The embedded control software is responsible for real-time control of spectrometer hardware and communication with the host computer. The host software handles user interface interaction, sequence parameter configuration, and post-processing of acquired data. Furthermore, an open and lightweight NMR data communication protocol is designed to support custom host software development based on specific user requirements, thereby significantly enhancing system flexibility and scalability. Experimental results demonstrate that the proposed palm-sized NMR spectrometer console operates reliably and offers considerable practical value.
