Wireless Monitoring System of Coal and Coal Gangue Mixing Ratio Based on Mon-Hermite Technology

The invention discloses a wireless monitoring system of coal and coal gangue mixing ratio based on non-Hermite technology, which comprises a signal generation monitoring device, an excitation coil, a receiving coil and a parallel plate capacitor. The signal generation monitoring device is connected with the excitation coil; the receiving coil is connected with the parallel plate capacitor to form an LC resonance system; the receiving coil is placed in parallel with the excitation coil, and the axis of the receiving coil and the axis of the excitation coil are on the same horizontal line; the signal generation monitoring device is used for generating pulse current and collecting reflected signals. The excitation coil generates an excitation initial magnetic field based on the pulse current; the LC resonance circuit induces the electromagnetic field to generate an induction magnetic field, and at the same time, LC resonance circuit feedbacks reflected signal to generation monitoring device based on the induction magnetic field. According to the invention, a sample to be measured is placed in a parallel plate capacitor; the mixing ratio of coal and coal gangue can be adjusted in the testing process without need for manual operation and automatic and intelligent sample measurement of the mixing ratio of coal and coal gangue is realized.
