Remote intelligent monitoring system of fire hydrant

The invention relates to a fire hydrant, in particular to a remote intelligent monitoring system of the fire hydrant. A controller bracket is arranged in a top cover of the fire hydrant; a fire hydrant rotary shaft is arranged in the center of the controller bracket; a valve sensor is arranged on the fire hydrant rotary shaft in a matching mode; a printed circuit board (PCB) is arranged on one side of the fire hydrant rotary shaft; a vibration sensor and a knocking-down sensor are arranged on the PCB; a micro control unit (MCU) and a transmitting antenna are arranged on one side of the PCB; the vibration sensor, the knocking-down sensor and the valve sensor are respectively connected with the MCU through a low-pass filtering circuit; each sensor detects each piece of information of the fire hydrant and then sends the information to the MCU; the MCU sends the obtained detection information to a remote communication server through a general packet radio service (GPRS) communication module; and a buzzer sends an
