Device for monitoring motion gesture of rotating disk of omnibearing propeller of submersible

The invention provides a device for the monitoring motion gesture of a rotating disk of an omnibearing propeller of a submersible. Linear scales are respectively arranged on the three hydraulic cylinders of the omnibearing propeller; a microprocessor sends out a command signal to determine a linear scale signal data channel; a data conversion unit receives the output signals of the linear scales corresponding to the hydraulic cylinders in real time, wherein the determined data signals are switched to a signal processing unit after level switch; the data signals are identified and processed bythe microprocessor of the signal processing unit and then transmitted to the signal processing unit, the signal processing unit converts the displacement and channel information of the linear scales into an RS232 signal and then is accessed to an upper computer through a communication interface unit; and the upper computer displays in real time and stores the data at the same time. The monitoringdevice has the characteristics of high acquisition precision, low work voltage and power consumption, high reliability, simple structure and the like.
