The lower end of a shell of the monitoring device is open and is coaxially fixed to a nut, and the tail end of a screw of a bolt extends into an inner cavity of the shell. An inductance coil is packaged on the side wall of an inner cavity of the shell, the RFID module is fixed to the top of the shell, and the two ends of the coil are connected into a circuit of the RFID module to form a closed loop. The electric signal change generated when the nut rotates relative to the bolt is sensed through the coil, and bolt loosening information is obtained. The RFID module is used for monitoring electric signals in real time, the upper computer is used for issuing monitoring commands and processing data, and the RFID reader is used for establishing two-way information communication between the RFID module and the upper computer. The problem of simultaneous monitoring of the connection states of a plurality of bolts under the working conditions that the bolts are relatively small in size and relatively dense in spaceflight satellites and the installation space of a monitoring device is very limited is solved.
