Abstract
A communicator in one aspect of the present disclosure includes a connector, a communication circuit, and a communication controller. The connector is electrically coupled to an electric working machine. The communication circuit performs wireless communication. The communication controller cyclically transmits operational information without specifying a recipient via the communication circuit in response to an operating mode of the communication controller being set to an operation-transmission mode. The operational information indicates an operating state of the electric working machine.
Claims17
A communication system comprising:
- a first communicating unit attached to an electric power tool;
- and
- a second communicating unit attached to a dust collector, the second communicating unit including:
- a communication circuit configured to receive and transmit a radio wave for wireless communication;
- a button configured to be pressed by a user of the second communicating unit;
- and
- a communication controller electrically connected to the communication circuit and to the button, the communication controller programmed to:
- transition to a wait-search mode;
- in response to the button being long-pressed during the communication controller being in the wait-search mode, transition to a registration-search mode;
- and
- in response to the button being long-pressed during the communication controller being in the registration-search mode, transition to a mobile-connection transmission mode,
- the wait-search mode corresponding to a setting for the communication controller to cyclically search a wait-notice via the communication circuit,
- the registration-search mode corresponding to a setting for the communication controller to cyclically search a registration-notice via the communication circuit, and
- the mobile-connection transmission mode corresponding to a setting for the communication controller to establish a connection with a mobile device via the communication circuit, the mobile device being independent from the first communicating unit.
11 more elements
A communicator comprising:
- a connector configured to be electrically connected to a first electric working machine;
- a communication circuit configured to receive and transmit a radio wave for wireless communication;
- and
- a communication controller electrically connected to the communication circuit, the communication controller configured to:
- transition to a first mode;
- and
- transition to a second mode during the communication controller being in the first mode,
- the first mode corresponding to a setting for the communication controller to establish, via the communication circuit, a connection with a second electric working machine or with an additional communicator, the additional communicator being electrically connected to the second electric working machine, and
- the second mode corresponding to a setting for the communication controller to establish a connection with a mobile device via the communication circuit, the mobile device being independent from the additional communicator.
6 more elements
An electric working machine comprising:
- a motor;
- a communication circuit configured to receive and transmit a radio wave for wireless communication;
- and
- a communication controller electrically connected to the communication circuit, the communication controller configured to:
- transition to a first mode;
- and
- transition to a second mode during the communication controller being in the first mode,
- the first mode corresponding to a setting for the communication controller to establish, via the communication circuit, a connection with an additional electric working machine or with an additional communicator, the additional communicator being electrically connected to the additional electric working machine, and
- the second mode corresponding to a setting for the communication controller to establish a connection with a mobile device via the communication circuit, the mobile device being independent from the additional electric working machine or from the additional communicator.
6 more elements
A method comprising:
- switching a first communicator to a first mode, wherein the first communicator is connected to a first electric working machine, the first mode corresponds to a setting for the first communicator to establish a connection with a second communicator, and the second communicator is connected to a second electric working machine;
- and
- switching the first communicator from the first mode to a second mode, wherein the second mode corresponds to a setting for the first communicator to establish a connection with a mobile device, and the mobile device is independent from the second electric working machine.
