Three-dimensional near-field vector scanning method and device

Abstract

The invention provides a three-dimensional near-field vector scanning method which comprises main thread and first thread which are performed in parallel. The main thread comprises steps of: acquiring scanning information, driving a motor to a target position, and triggering the first thread which executes data collection. The invention also provides a parallel scanning device of the three-dimensional near-field vector so as to realize the above method. The device comprises: a main thread working module 100 used for acquiring the scanning information, driving the motor to the target position and triggering a first thread module to work; the first thread working module 101 used for executing data collection; and a second thread working module 102 used for executing data output. By reading points in a scanning spot queue, acquiring data and printing or outputting data in parallel, serial waiting time is minimized, and data acquisition and analysis efficiency of a near-field vector scanning system is substantially raised.

Description

【Technical field】 [0001] The invention relates to the field of electromagnetic field detection, in particular to a scanning method and device for a three-dimensional near-field vector. 【Background technique】 [0002] Magnetic fields and electromagnetic waves are widely used in various fields of modern society, such as in the field of medical equipment, and the use of excited magnetic fields to detect various diseases of the human body has achieved good results. People have a better understanding of the three-dimensional near-field vector, the distribution of magnetic field strength and direction, and the measurement of characteristics.

Problems solved by technology

[0005] like figure 2 As shown, the existing technology needs to stand still for a period of time every time it moves to a scanning point, and then continue to move after waiting for the data acquisition device to complete data acquisition, which causes the problem of too long scanning time, because when the scanning area is large, the scanning interval is small In this case, the number of scanning points is very alarming, so the total static waiting time is unacceptable, for example, each scanning point is static for 50 milliseconds, when the area of ​​scanning points is 500mm*500mm, and the scanning interval is 1mm, It takes 54 hours to wait for data collection. If the scanning interval is set to 0.1mm, the time required for the scanning task is unimaginable.
