Work machine system and work machine
A work machine system is provided. The system comprises: a first work machine and a second work machine, each being configured to conduct a work in a predetermined work area. The first work machine includes a first position detector to detect a position of the second work machine and a transmitter to transmit, to the second work machine, travel control information in accordance with the position of the second work machine. The second work machine includes a position indicator to display a position for the first work machine and a receiver to receive the travel control information from the first work machine, and a travel controller to control travel based on the travel control information.
1. A work machine system comprising: a first work machine; and a second work machine, each being configured to conduct a work in a predetermined work area,
the first work machine including:
a first position detector configured to detect a position of the second work machine, periodically; and
a transmitter configured to transmit, to the second work machine, travel control information in accordance with the position of the second work machine,
the second work machine including:
a position indicator configured to display a position for the first work machine; and
a receiver configured to receive the travel control information from the first work machine; and
a travel controller configured to control travel based on the travel control information in accordance with reception of the travel control information,
wherein the position indicator emits light of a predetermined pattern in response to an instruction from the first work machine, and
the first position detector detects the position of every second work machine, based on the predetermined pattern.
2. The work machine system according to claim 1 , wherein
the travel control information includes a target speed and a target turning angle of the second work machine.
3. The work machine system according to claim 1 , wherein
the first position detector optically detects a display of the position by the position indicator.
4. The work machine system according to claim 1 , wherein
the position indicator includes a marker in which a predetermined pattern is recorded.
5. The work machine system according to claim 4 , wherein
the pattern includes a unique pattern for every second work machine, and
the first position detector detects a position of every second work machine, based on the pattern.
6. The work machine system according to claim 3 , wherein
the position indicator displays toward at least one of ahead or behind the second work machine, and
the first position detector detects the display by the position indicator of the second work machine.
7. The work machine system according to claim 1 , wherein
the position indicator transmits a signal of a specific frequency to display the position, and
the first position detector detects the signal of the specific frequency, and detects the position of the second work machine, based on the signal that has been detected.
8. The work machine system according to claim 1 , wherein
the first work machine further includes:
a second position detector configured to detect a position of the first work machine; and
a travel controller configured to control travel of the first work machine, based on the position that has been detected by the second position detector.
9. The work machine system according to claim 1 , wherein
the first work machine further includes a travel controller configured to control travel in response to an operation by an operator.
10. A first work machine configured to conduct a work in a predetermined work area, the first work machine comprising:
a first position detector configured to detect a position of a second work machine, periodically; and
a transmitter configured to transmit, to the second work machine, travel control information in accordance with the position of the second work machine,
wherein the second work machine has a position indicator that emits light of a predetermined pattern in response to an instruction from the first work machine, and
the first position detector detects the position of every second work machine, based on the predetermined pattern.
11. A second work machine configured to conduct a work in a predetermined work area, the second work machine comprising:
a position indicator configured to display a position for a first work machine;
a receiver configured to receive travel control information from the first work machine; and
a travel controller configured to control travel, based on the travel control information in accordance with reception of the travel control information,
wherein the position indicator emits light of a predetermined pattern in response to an instruction from the first work machine, and
the first work machine has a first position detector that detects the position of the second work machine, based on the predetermined pattern.
