Wireless marine propulsion shafting monitoring system

The utility model discloses a wireless marine propulsion shafting monitoring system, which belongs to the field of marine propulsion shafting test. The system comprises two Hall speed-measuring sensors, two eddy current sensors, an industrial control computer, a local monitoring computer and a plurality of rectangular magnetic steels used for assisting monitoring; all rectangular magnetic steels are divided into two groups; each rectangular magnetic steel group is at equal intervals fixed around a transmission shaft close to a diesel engine end of the propulsion shafting; the distance between the two magnetic steel groups is at least 40cm; each magnetic steel group uses one Hall speed-measuring sensor for sensing and detection; the two eddy current sensors respectively detect transverse and longitudinal vibration displacement of the transmission shaft; the output ends of all sensors are connected onto the industrial control computer; and the industrial control computer is in WiFi connection with the local mon
