Abnormality reporting system for electric tools

A system comprising:

• a plurality of electric devices including at least a first electric tool having a first report unit and a second electric tool having a second report unit;
• and
• a communication terminal connected to the electric devices via wireless communication, the communication terminal having a third report unit,
• wherein the communication terminal includes a communication-terminal-side control unit that determines whether abnormality has occurred in any of the electric devices based on information acquired from the electric devices via the wireless communication,
• when the communication-terminal-side control unit determines that abnormality has occurred in the first electric tool, the occurrence of abnormality in the first electric tool is reported by the second report unit included in the second electric tool other than the first electric tool in which the occurrence of abnormality is determined and the third report unit included in the communication terminal,
• wherein the communication terminal includes an input unit that accepts an input of a number representing the number of the electric devices scheduled to operate, and
• wherein the communication-terminal-side control unit determines that the abnormality has occurred in the electric device when the electric devices exceeding the number of the electric devices scheduled to operate are in operation.

A system comprising:

• a plurality of electric tools each having a motor, an operation switch, a tool-side control unit, and a tool-side communication unit;
• and
• a communication terminal connected to the respective electric tools via wireless communication, and having an input unit, a display unit, a terminal-side control unit, and a terminal-side communication unit,
• wherein the terminal-side control unit is configured to control the input unit to accept registrations of the plurality of electric tools, when the plurality of electric tools are within a wireless communication range in which the plurality of electric tools can establish the wireless communication with the communication terminal,
• wherein the terminal-side control unit is configured to control the input unit to accept a selection of an electric tool scheduled to operate among the registered electric tools, when the electric tool scheduled to operate is within the wireless communication range, and
• wherein, when the electric tool scheduled to operate is brought out of the wireless communication range, the terminal-side control unit is configured to control the display unit to report an abnormality in the electric tool scheduled to operate and to display a name of the electric tool scheduled to operate.
