The present invention discloses a space magnetic field intensity distributed synchronous detection device and method. The space magnetic field intensity distributed synchronous detection device comprises a magnet measurement node array installation panel, magnet measurement nodes and a control terminal. There are provided n rows and m columns of magnet measurement nodes arranged on the magnet measurement node array installation panel, each magnet measurement node is provided with an installation sampling holder. Control pins of all the installation sampling holders are connected with the control terminal through a control bus in such a manner to constitute a sensor array. The present invention further discloses a space magnetic field intensity distributed synchronous detection. The control terminal is configured to send a synchronous acquisition signal to all the magnet measurement nodes, the sampling holders on the magnet measurement nodes are located in the hold mode, and the control terminal is configured to acquire a magnetic field intensity of each node through a high speed roll poling method. According to the invention, the synchronous acquisition of space multi-node magnetic field intensities may be realized, the instantaneity is good and the splicing development is easy, etc. Moreover, the magnetic field detection resolution may be changed through the jump-point acquisition, and at the same time a lower sampling rate may be used for the detection of the high frequency magnetic field.
Description
technical field [0001] The invention relates to a distributed synchronous detection device and method for spatial magnetic field strength, belonging to the technical field of spatial magnetic field strength measurement. Background technique [0002] At present, almost any technical field is inseparable from magnetic field measurement. Taking wireless power transmission technology as an example, magnetic fields are now mainly used as energy transmission channels. Therefore, the measurement of the space magnetic field is of great significance to the research and development of the wireless power transmission system, especially for the magnetic resonance coupling wireless power transmission technology. [0003] Although there are many methods for measuring the magnetic field, few patents and papers introduce how to realize the simultaneous acquisition of the magnetic field at multiple points in space. Although existing patents involve distributed detection of magnetic fields, ...
