PURPOSE: A dredging system is provided to improve dredging efficiency by outputting optimal operation signals using signals inputted from a cutter drive unit, a generation device, and a pump. CONSTITUTION: A dredging system comprises a master control unit, a master control monitoring and controlling unit, a main control unit, and a power generation unit. The master control unit is composed of a communication interface(110), an AD converter(120), a DA converter(130), a cycle digital signal input unit, a relay digital out interface(140), and a power control unit(150). The master control monitoring and controlling unit is composed of a display unit, a pulse generation unit(210), a signal in/out check unit(220), an armature electric signal check unit(230), an amplifier(240), an armature pulse driver, an armature pulse generation unit(260), a field pulse driver(270), and a field pulse generation unit(280). The main control unit is composed of a switch unit(300) for turning on/off the master control unit and the master control monitoring and controlling unit. The power generation unit supplies power to a cutter drive unit, a ladder drive unit, and a swing unit. |
