Abstract

The present invention is applicable to the technical field of medical auxiliary equipment and provides a method for acquiring and transmitting quantum magnetoencephalogram data based on a network architecture. The method comprises the following steps: step S001, signal acquisition and transmission are conducted, a signal acquisition and transmission device of a quantum magnetoencephalogram systemuses the network architecture to conduct module-based design of different types of signals and conduct the acquisition in different modules; step S002, data summarization is conducted, finally, the step S001 is summarized to be transmitted to an upper computer by an interchanger, and the upper computer distinguishes data sent by different IP addresses to differentiate signal types; and step S003,command control is conducted, instructions control detectors and at the same time monitor working states of the detectors during work of the detectors, and control units of the detectors, the upper computer and a control module conduct command transmission, and complete control functions of the quantum detectors. Thereby, an isolation circuit is designed to satisfy communication and at the same time can also ensure reliability and stability of the system.

Description

technical field [0001] The invention relates to the technical field of medical auxiliary equipment, in particular to a method for collecting and transmitting quantum magnetoencephalogram data based on a network architecture. Background technique [0002] Magnetoencephalography images the brain by recording the magnetic field generated by neural activity in real time. The quantum magnetoencephalogram composed of an atomic magnetometer that uses quantum manipulation of light to interact with alkali metal atoms is the best choice for future magnetoencephalography. Quantum magnetoencephalography requires synchronous high-frequency sampling of multi-channel detectors, and the quantum detector array also needs strict temperature monitoring and feedback. At the same time, quantum magnetoencephalography also needs to cooperate with electroencephalogram, electrooculogram, electrocardiogram and other physiological electrodes to collect synchronously, so as to achieve the purpose of re...
