Title:
自走式作業機及び自走式作業機の制御システム
Document Type and Number:
Japanese Patent JP7201203
Kind Code:
B2
Abstract:
To provide a self-travelling work machine and a control system of the self-travelling work machine capable of performing a remote operation, reducing the number of components involved in power transmission control, and being put under an operator's control even when a radio signal is blocked.SOLUTION: A self-travelling work machine and a control system of the self-travelling work machine include a travelling unit D, a work unit K, a lifting and lowering unit F for freely lifting and lowering the work unit K, an operation unit B for remotely controlling the travelling unit D, the work unit K, and the lifting and lowering unit F, and a converter control device E for converting a signal sent from the operation unit B and outputting a signal for controlling rotations of a travelling motor 15, a work motor 51, and a lifting and lowering motor 61. When the signal from the operation unit B is blocked for a set time, the converter control device E determines that power supply of the operation unit B as a transmitter is in a cutoff state, and outputs a stop signal to the travelling motor 15, the work motor 51, and the lifting and lowering motor 61 to bring them into a stop state.SELECTED DRAWING: Figure 1
