Working machine control device

A working machine control device capable of remotely controlling a working machine provided with an actuator, a control valve which controls activation of the actuator, a machine-side operation device which outputs a pilot pressure according to operation to the control valve, and an operation pattern switching valve which is provided in a pilot line between the machine-side operation device and the control valve and switches a machine-side operation pattern as a combination of operation of the machine-side operation device and activation of the actuator, the working machine control device comprising:

• a slave-side device which is disposed in the working machine and controls activation of the actuator by controlling a pilot pressure of the pilot line;
• and
• a master-side device which is provided outside the working machine and is radio-communicable with the slave-side device, and transmits a command for controlling activation of the actuator to the slave-side device, wherein
• the slave-side device transmits information of a machine-side operation pattern selected by the operation pattern switching valve to the master-side device, and
• the master-side device includes:
• a master-side operation device which outputs a first command according to operation of an operator;
• an operation pattern switching unit which switches a master-side operation pattern as a combination of the first command and a second command to be transmitted to the slave-side device for operating the machine-side operation device based on an instruction from an operator who refers to the information of the machine-side operation pattern, and converts the first command to the second command according to the switched master-side operation pattern;
• and
• a communication unit which transmits the second command converted by the operation pattern switching unit to the slave-side device.
