Detailed description of the invention
The invention will be further described with embodiment below in conjunction with the accompanying drawings, but protection scope of the present invention is not limited to the scope of embodiment statement.
Metal detector of the present invention includes by formula detector 100 or hand-held detector 200.
It is an embodiment schematic diagram of metal detector of the present invention with reference to Fig. 1, Fig. 1.Agent structure, transmitting coil 101, receiving coil 102, main frame (not shown) is included by formula detector 100.Main frame is used for controlling, and sends pumping signal and receives the signal of transmitting coil 101 to transmitting coil 101, receiving coil 102.
It is the another embodiment schematic diagram of metal detector of the present invention with reference to Fig. 2, Fig. 2.Hand-held detector 200 includes agent structure, transmitting coil 201, receiving coil 202, main frame 203.Main frame 203 is used for controlling, and sends pumping signal and receives the signal of transmitting coil 201 to transmitting coil 201, receiving coil 202.
According to Maxwell's Theory of Electromagnetic Field, launching pumping signal from transmitting coil 101, through aerial propagation, receiving coil 102 has faradic current and induction electromotive force.Particularly, when there being other metal parts can produce eddy current effect near transmitting coil 101 or receiving coil 102, thus faradic current and the induction electromotive force that receiving coil 102 produces is affected.
Refer to the method for displaying image flow chart that Fig. 3, Fig. 3 are sorting metals of the present invention.
Step S301, by the measured object induction region by the receiving coil of metal detector；
Step S302, obtains phase property value R of measured object.
Concrete, according to measured object by before the induction region of the receiving coil of metal detector and measured object by the induction region of the receiving coil of metal detector time, faradic current that receiving coil receives and induction electromotive force, can extract waveform phase difference, draw phase property value R of measured object.
Need explanation, transmitting coil pumping signal such as 5360Hz based on same hardware detection and same frequency, phase property value R is relevant to the material composition of measured object, therefore, it is fixing that special metal demarcates phase property value R of thing, but for different receiving coils, due to the difference on its analog feature, by different receiving coils, it is different that the metal measured demarcates phase property value T of thing, and embodiments of the invention only discuss the situation of the transmitting coil pumping signal of same hardware detection and same frequency.
Step S303, according to phase property value R and the demarcation thing phase property table of measured object, the corresponding metal of display demarcates the classification chart picture of thing.
Concrete, demarcate phase property value T having metal demarcation thing in thing phase property table, phase property value R of measured object is contrasted one by one with T.Judge that phase property value R of measured object and each metal demarcate the difference of phase property value T of thing within the scope of presetting, if meeting in default scope, then it is assumed that the material composition that described metal demarcates thing is most like with measured object.Measured object is classified as doubtful article and shows that described metal demarcates the classification chart picture of thing.The scope preset can be set at the needs of actually used process according to user, and the size of preset range determines tolerance degree during test measured object.Particularly, if phase property value R of measured object and multiple metals demarcate the difference of phase property value T of thing all within the scope of presetting, then can further judge that the immediate metal of phase property value R with measured object demarcates phase property value T of thing, the material composition that described immediate metal demarcates thing is regarded as most like with measured object.
Such as, the phase property value having iron weapon in demarcation thing phase property table is 60, and the scope preset is 10, when the phase property value recording measured object is 65, then shows the classification chart picture of iron weapon and reports to the police.
By the way, security staff can be allowed can quickly to know doubtful taxonomy of goods entrained with measured, it is provided that effective warning message directly perceived, improve detection efficiency, provide direct information for security staff's quadratic search.
Additionally, another kind of judgment rule can be used, specific as follows: to demarcate the phase property value scope having one or more metal demarcation thing in thing phase property table, the phase property value scope that the metal in phase property value R of measured object and demarcation thing phase property table demarcates thing is judged.Within the scope of judging the phase property value whether phase property value R of measured object demarcates thing at a certain metal, if it is, it is most like with measured object to think that this metal demarcates the material composition of thing.Measured object is classified as doubtful article and shows that described metal demarcates the classification chart picture of thing.
Such as, the phase property value having iron weapon in demarcation thing phase property table is 40-80, when the phase property value recording measured object is 65, then shows the classification chart picture of iron weapon and reports to the police.
Fig. 4 is the method for displaying image schematic diagram of sorting metals of the present invention, refer to Fig. 4.In such scheme, if measured object is classified as doubtful article, then display screen 400 can show that described metal demarcates the classification chart of thing as 401.Iron cutter shown in Fig. 4, it will be appreciated that testing result thinks that doubtful article are as 401 article with identical material composition with classification chart, rather than the prompting doubtful article of security staff determine it is iron cutter.It addition, classification chart picture can be many forms, as the classification chart picture of ferrum class article can use other iron item pictures to substitute, such as the picture of rifle, it is also possible to make visual alerts with the various ways such as word, color.Different classification chart pictures represents different metal and demarcates phase property value or the phase property value scope of thing.Its phase property value corresponding such as classification chart picture or the phase property value scope of the classification chart picture of the iron weapon of instrument, cutter or rifle, the classification chart picture of easy-to-draw tank body, the classification chart picture of tinplate tank body, the classification chart picture of copper aluminum body and mobile phone can be provided with.
By such scheme, security staff can be allowed can to know rapidly doubtful taxonomy of goods entrained with measured, it is provided that effective warning message directly perceived, improve detection efficiency, security staff can carry out quadratic search according to its degree of danger.
