Ship Main Engine Rotation Rate Measured Based on Opto-elemetronic Method

Based on thorough analysis of the integrated information transmission platform, a setup is demonstrated that can measure ship main engine rotating rate based on opto-elemetronic method, which includes opto-elemetronic sensor block, data collecting terminal, display terminal and power supply module. Then, combing V.35 channel integrated information transmission platform with protothreads mutiple-thread technology, the method to configure forward and reverse V.35 transmission channel has been developed, which can effectively reduce the demodulation error caµsed by signal distortion, simplify the wiring of the system, and enhances the deployment flexibility of time code terminal.
