Design of Controlling System of the Subsea Sampling Drilling Rig

In order to carry out a remote controlling of the subsea sampling,provide a communicating method which is based on RS485 to complete the communication between the onboard equipment and the subsea sampling rill;and provide a controlling method which is micro-computer to complete the adjustment of the frequency of the vibrator and the controlling of electromagnetic valve.It introduces the holistic design,and the design of hardware circuit and software.
