Control system and control method of unmanned engineering machinery

A control method of an unmanned engineering machinery, comprising:

• receiving, by a slave computer of the unmanned engineering machinery, a first current sensing value fed back by at least one first sensing device in a working device of the unmanned engineering machinery and a second current sensing value fed back by at least one second sensing device in a slewing device of the unmanned engineering machinery;
• sending, by the slave computer, the first current sensing value and the second current sensing value to a master computer of the unmanned engineering machinery;
• generating, by the master computer, a control instruction according to the current sensing value and a predetermined target sensing value of the sensing device;
• sending, by the master computer, the control instruction to an execution device of the unmanned engineering machinery through the slave computer;
• and
• performing, by the execution device, a control operation corresponding to the control instruction on the unmanned engineering machinery.
