Metal marker tag detection system based on eddy current technology
2015
The invention discloses a metal marker tag detection system based on an eddy current technology. The metal marker tag detection system comprises an alternating current signal generator, and the system further comprises a detection coil, a phase and amplitude detector, a direct current offset amplifier, an analogue-to-digital converter and a digital signal processor all which are sequentially connected, wherein the alternating current signal generator is respectively connected with the detection coil and the phase and amplitude detector. The beneficial effect of the system is that the metal marker tag detection system based on eddy current detection belongs to non-contact detection, is high in detection speed, and easy to realize automatic detection. The detector is high in sensitivity and the higher-density information can be recorded. The detection system is small in volume and can form portable detection equipment.
