It should be noted that the acousto-magnetic detection access control system of the present embodiment belongs to a single-bit radio frequency identification system, and the adopted modulation method is a digital modulation method of amplitude keying. The modulation signal is a binary coding signal and consists of a single bit sequence in two states of 0 and 1, the pulse maintaining time is, the pulse turn-off time is, the pulse period is 20ms, and the required pulse amplitude is larger; the carrier signal is a 58kHz low-frequency sinusoidal signal; the modulated signal is an ASK signal having an amplitude modulation factor of 100%. When the acoustic magnetic label enters an alternating magnetic field excited by ASK and the resonance frequency of the label is consistent with the carrier frequency, a resonance phenomenon can be generated in the label due to the magnetostrictive effect. When the excited alternating magnetic field is turned off, the resonance signal can be maintained for a period of time according to the piezomagnetic effect of the tag, and damped oscillation occurs; in addition, since mechanical energy and magnetic field energy are alternately converted, the resonance signal is an acousto-magnetic composite signal, which is the meaning of an acousto-magnetic system. The resonance signal not only extends as a space of the excitation magnetic field, but also has the characteristics of an ultrasonic wave. Thus, the induction coil in the receiver easily detects the resonance signal, thereby driving the alarm device 4 of the system. The alternating magnetic field acoustomagnetic identification principle of the acoustomagnetic label is as follows: one is that the center frequency of the signal is 58kHz, the bandwidth is 57.8kHz to 58.2kHz, and the signal is the narrowest in all electronic anti-theft systems at present, so the signal is extremely unlikely to be interfered to cause false alarm. The second is the process of system judging label signal. When the transmitting signal is switched off, the receiver continuously receives the resonance signal for 6 times, and if the power and the frequency of the resonance signal are the same each time, the resonance signal is determined to be a tag signal; for example, it is impossible to generate 6 identical signals within one second for an external interference signal; the identification process is repeated, so that the label signal can be accurately judged, and the operation of almost zero false alarm is realized. Compare radio frequency entrance guard, the utility model discloses an acoustomagnetic detection entrance guard not only the wrong report rate is low and the interference killing feature far exceeds radio frequency entrance guard, but the entrance guard that general shop was used for detecting the magnetic stripe all does not take switch door 3, if need if switch door 3 then need change entrance guard overall structure, need change radio frequency identification even, the engineering is big, and is with high costs, and the entrance guard of this embodiment only needs to reform transform on original basis.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and replacements can be made without departing from the technical principle of the present invention, and these modifications and replacements should also be regarded as the protection scope of the present invention.
