That is, the adjustment of the relative positions of the first substrate 211a and the second substrate 211b corresponds to the adjustment of the positions between the first antenna 222a and the second antenna 222 b.
Specifically, for the capacitive sensor 2111, if the relative distance between the two substrates changes, the corresponding capacitance and voltage will be adjusted accordingly. The integrated radio frequency signal transmitting unit 220 and the monitoring unit 210 are arranged between the hoop structure 110 and the transportation pipeline 20, if there is a position adjustment between the hoop structure 110 and the transportation pipeline 20, there is an electrical signal change between the corresponding first substrate 211a and second substrate 211b, and then the integrated radio frequency signal transmitting unit 220 transmits the changed signal to the radio frequency read-write module 300 in a radio frequency mode, that is, the position change can be fed back according to the signal change. It should be noted that, if there is a position adjustment between the hoop structure 110 and the transport pipe 20, the hoop structure 110 is represented to adjust the bearing condition of the transport pipe 20, and capture and judge the bearing condition in time, which is beneficial to realizing the acquisition of the health performance of the hoop structure 110 by the monitoring system 10.

In this case, if the space between the hoop structure 110 and the transport pipe 20 is too small, the other side of the second antenna 222b will contact the transport pipe 20, and the space between the first substrate 211a and the second substrate 211b will be compressed according to the space between the hoop structure 110 and the transport pipe 20, the capacitance and the voltage of the capacitive sensor 211 will also change accordingly, and the rf signal transmitting unit 220 will transmit the change to the rf read/write module 300 by means of rf. Similarly, the first antenna 222a is suspended at one side and the position, the other side is in contact with the first substrate 211a, the second antenna 222b is in contact with the second substrate 211b, and the other side is in contact with the transport pipe 20.
