Abstract

The invention discloses a propeller shaft remote sensing type strain measuring system used for ship, a measuring device, and a measuring method. The propeller shaft remote sensing type strain measuring system used for the ship comprises a rotor acquisition system, a stator analysis system, and a wireless sensing power supply system. The rotor acquisition system is used for detecting micro-strain signals and rotation speed/turning signals of a transmission shaft, and is used to transmit the detected signals to the rotor analysis system by using zigbee wireless technology. The stator analysis system is used to receive, analyze, store, and display the micro-strain signals and rotation speed/turning signals. The wireless sensing power supply system adopts an OC-type coiling for wireless powersupply and power supply excitation, and is used to provide the power supply for a stress piece torque measurement bridge, rotation speed/turning sensors. The propeller shaft remote sensing type strainmeasuring system is advantageous in that by aiming at the transmission shafts having different materials such as metal and non-metal and different diameters, a brand new universal type OC-type wireless sensing power supply design is adopted to satisfy requirements on the measurement of the transmission shafts of various materials and sizes, and the real-time torque, the power, the rotation speedand the turning of the transmission shafts during the rotary working state are monitored.

Description

technical field [0001] The invention relates to the technical field of ship measurement and monitoring, in particular to a marine propulsion shaft torque / power / speed / steering remote-sensing strain measurement system, a measuring device and a measuring method thereof. Background technique [0002] Torque and shaft power are important parameters that reflect the performance of the entire power system. Especially in the field of ships, the degree of intelligence of ships is getting higher and higher, and the size of ships is getting bigger and bigger. The current transmission torque meter on the market can no longer meet the measurement of large shafting torque and shaft power like ships. Moreover, the torque meter used in the traditional industry cannot measure and calculate the shaft power, and the installation must destroy the original shafting, which cannot meet the requirements of marine use. [0003] For example, the published patent CN109341915A discloses an online moni...
