PROBLEM TO BE SOLVED: To provide an air pressure monitoring device using a pressure sensor for TPMS (Tire Pressure Monitoring System) capable of monitoring always an air pressure of a pneumatic fender, and to provide its centralized control system. SOLUTION: A plurality of pressure sensors 3 with each transmitter for TPMS are installed inside the pneumatic fender 2 installed on a quay wall 1, and the pressure sensors 3 transmit an air pressure detection signal repeatedly in due order toward a receiving device 5 so as to continue each transmission state at prescribed intervals.
