It is expressly noted that all such similar substitutions and modifications will be apparent to those skilled in the art, and are deemed to be included in the present invention. While the methods and applications of this invention have been described in terms of preferred embodiments, it will be apparent to those skilled in the relevant art that variations and modifications can be made in the methods and applications described herein, and in the practice and application of the techniques of this invention, without departing from the spirit or scope of the invention.
The research of the applicant shows that: existing multi-source detection is prone to errors when the source position matches the source intensity, such as matching a's intensity data to B's source. Therefore, when the electromagnetic source with the electromagnetic intensity higher than the standard value is found, the electromagnetic source is easy to be worn on the articles, and the normal electromagnetic source is misjudged as the abnormal electromagnetic source.
Therefore, the embodiment of the invention provides an intelligent electromagnetic detection method which is applied to a signal detector, wherein the signal detector comprises three signal detection units which are arranged in a triangular manner, namely a first signal detection unit, a second signal detection unit and a third signal detection unit; as shown in fig. 1, the method includes:
step S1, acquiring three groups of electromagnetic signal intensity data, namely first electromagnetic signal intensity data, second electromagnetic signal intensity data and third electromagnetic signal intensity data, by three signal detection units of a signal detector aiming at least two electromagnetic sources in a target environment.
It should be noted that the electromagnetic source generally corresponds to an electronic device, and the location is known. The embodiment of the invention is also suitable for electromagnetic detection in a multi-electromagnetic source environment. Three groups of electromagnetic signal intensity data acquired by the signal detector at first are mixed data of electromagnetic waves emitted by each electromagnetic source, and electromagnetic intensity corresponding to a specific electromagnetic wave can be obtained through filtering.
And S2, respectively filtering the first electromagnetic signal intensity data, the second electromagnetic signal intensity data and the third electromagnetic signal intensity data at least one optional frequency.
The method comprises the steps of obtaining first electromagnetic optional frequency component intensity corresponding to an optional frequency through filtering in first electromagnetic signal intensity data, obtaining second electromagnetic optional frequency component intensity corresponding to the optional frequency through filtering in second electromagnetic signal intensity data, and obtaining third electromagnetic optional frequency component intensity corresponding to the optional frequency through filtering in third electromagnetic signal intensity data.
It should be noted that, in the embodiment of the present invention, a plurality of selectable frequencies are divided, where the selectable frequency is a frequency band, so long as the division is thin enough to ensure that each selectable frequency band corresponds to only one electromagnetic wave of the electromagnetic source. The first electromagnetic selectable frequency component intensity, the second electromagnetic selectable frequency component intensity and the third electromagnetic selectable frequency component intensity are electromagnetic intensities of electromagnetic waves corresponding to selectable frequencies in the first signal detection unit, the second signal detection unit and the third signal detection unit respectively.
0026. It should be noted that, in the embodiment of the present invention, the operations in steps S2 to S5 are performed on all the preset multiple selectable frequencies, so that the electromagnetic sources corresponding to the respective selectable frequencies are obtained for matching. The preset plurality of selectable frequencies together form an electromagnetic detection frequency band required in the target environment.
Step S3, a first track circle of the position to be determined of the electromagnetic source to be matched corresponding to the selectable frequency is obtained according to the intensity of the first electromagnetic selectable frequency component, the intensity of the second electromagnetic selectable frequency component, the first position of the first signal detection unit and the second position of the second signal detection unit; obtaining a second track circle of the position to be determined of the electromagnetic source to be matched corresponding to the selectable frequency according to the first electromagnetic selectable frequency component intensity, the third electromagnetic selectable frequency component intensity, the first position of the first signal detection unit and the third position of the third signal detection unit; and obtaining a third track circle of the position to be determined of the electromagnetic source to be matched corresponding to the selectable frequency according to the second electromagnetic selectable frequency component intensity, the third electromagnetic selectable frequency component intensity, the second position of the second signal detection unit and the third position of the third signal detection unit.
It should be noted that, the principle according to which the trajectory circle is obtained in the embodiment of the present invention is that the electromagnetic intensity of an electromagnetic source at a certain position is inversely proportional to the square of the distance. The electromagnetic sources to be matched are the electromagnetic sources corresponding to the filtered selectable frequencies, and each track circle is a possible track obtained by calculating the electromagnetic sources to be matched according to the data.
In a specific embodiment, the first signal detecting unit, the second signal detecting unit and the third signal detecting unit are arranged in an equilateral triangle, and step S3 includes:
taking the connecting line of the first signal detection unit and the second signal detection unit as an abscissa axis, taking the midpoint of the connecting line of the first signal detection unit and the second signal detection unit as an origin, taking the line perpendicular to the connecting line of the first signal detection unit and the second signal detection unit as an ordinate axis, and taking the coordinate of the first solving position as an ordinate axis

It should be noted that, the arrangement of the detection signal units by adopting the equilateral triangle can solve the track circle more easily, reduce the calculated amount and reduce the complexity.
In a specific embodiment, a schematic diagram of determining a common intersection point between triangularly arranged detection signal units and a locus circle of a position where an electromagnetic source to be matched is to be determined corresponding to an optional frequency is shown in fig. 3, 301 is a first signal detection unit, 302 is a second signal detection unit, 303 is a third signal detection unit, and 304 is a first solving position.
And S4, determining a first solving position of the electromagnetic source to be matched according to the common intersection point among the first track circle, the second track circle and the third track circle.
It should be noted that the first track circle, the second track circle and the third track circle are theoretical positions where the electromagnetic source to be matched may exist, which are obtained by solving according to three sets of different data. The common intersection point is thus the common solution of the three trajectory circles, thereby determining the unique solution.
Step S5, according to the recorded positions of the stored electromagnetic sources and the first solving positions of the electromagnetic sources to be matched in the target environment, the electromagnetic sources to be matched in the stored electromagnetic sources are the matched electromagnetic sources, and the first electromagnetic selectable frequency component intensity, the second electromagnetic selectable frequency component intensity and the third electromagnetic selectable frequency component intensity are matched to the matched electromagnetic sources.
The stored electromagnetic source is an electromagnetic source whose recorded position is not known about the intensity data, and the stored electromagnetic source needs to be matched with the corresponding intensity data.
In a specific embodiment, the plurality of signal detectors are provided, the selectable frequencies of the corresponding filters of each signal detector are different and jointly form a full frequency section required by electromagnetic detection in the target environment, and each signal detector and the corresponding filter work simultaneously and jointly detect electromagnetic signal intensity data of each electromagnetic source in the target environment.
It should be noted that, a plurality of detectors and filters may be used to match electromagnetic sources corresponding to different selectable frequencies at the same time, so that the matching time may be reduced, and the matching efficiency may be improved.
In one embodiment, the method further comprises:
and (5) repeating the steps S2 to S5 by adopting different selectable frequencies until all electromagnetic sources to be matched in the target environment are matched.
In this embodiment, the same detector is used to match the corresponding electromagnetic sources with different selectable frequencies, so that the structure of the corresponding device of the present invention can be simplified and the cost can be reduced.
Optionally, in step S5, matching the electromagnetic source to be matched among the stored electromagnetic sources to be the matched electromagnetic source according to the recorded position of each stored electromagnetic source and the first solving position of the electromagnetic source to be matched in the target environment, including:
and obtaining the position of the stored electromagnetic source closest to the first solving position in the recorded positions of the stored electromagnetic sources in the target environment, and determining the position of the stored electromagnetic source closest to the first solving position as the matched electromagnetic source.
It should be noted that, in the simplest matching process, a stored electromagnetic source closest to the first solving position is determined from each stored electromagnetic source, and the stored electromagnetic source is matched with the signal intensity data corresponding to the first solving position.
According to the embodiment of the invention, the electromagnetic source position is matched with the electromagnetic intensity data, so that large-scale equipment emitting out-of-standard electromagnetic radiation can be rapidly determined, and further the harm of excessive electromagnetic radiation to human bodies is avoided. Meanwhile, when the exceeding electromagnetic radiation is used as a fault index of the large-scale equipment, the embodiment of the invention can also determine the faulty large-scale equipment.
The embodiment of the invention sets the signal detection units in triangular arrangement, so as to obtain three groups of electromagnetic signal intensity data, and then carries out the same selectable frequency filtering to obtain three electromagnetic selectable frequency component intensities; according to the electromagnetic selectable frequency component intensity and the position of the signal detection unit, three track circles of the position where the electromagnetic source to be matched corresponding to the selectable frequency is to be determined are obtained, and the track circle common intersection point is determined as a first solving position of the electromagnetic source to be matched; and then matching the first solving position with the recorded electromagnetic source position, so that the electromagnetic source position and the intensity data thereof are accurately matched. According to the embodiment of the invention, the matching accuracy of the electromagnetic source position and the electromagnetic intensity data in the multi-electromagnetic source detection can be improved by solving the theoretical position of each electromagnetic source in the target environment and then matching the theoretical position with the recorded actual position.
According to the principle that the electromagnetic intensity is inversely proportional to the distance bisection, the method for solving the theoretical position of the electromagnetic source by adopting the track circle intersection point has the advantages of simplicity and high accuracy.
The embodiment of the invention can adopt a plurality of signal detectors to correspondingly and simultaneously detect electromagnetic sources with different wavelengths for position matching. Thus, the matching time can be reduced, and the matching efficiency can be increased.
The embodiment of the invention can also adopt only one signal detector to detect electromagnetic sources with different wavelengths at different times for position matching. Thus, the structure can be simplified and the cost can be reduced.
To sum up. The embodiment of the invention can effectively improve the matching accuracy of the electromagnetic source position and the electromagnetic intensity data in the multi-electromagnetic source detection environment.
